If you split the shape right along the bottom of the first part, you get two parallelograms. If you split it like you split it the first time and then split it along the side of the bottom parallelogram you get a triangle, a parallelogram, and a trapezoid. Then, because the area of a parallelogram is A=bh, you can substitute the numbers in. 5*12=60 and 6*11=66. However, this is not all, remember to add the area together! 60+66=126 so D is also true.

Benjamin invests money in a bank account which gathers compound interest each year. After 2years there is $658.20 in the account. After 5years there is $710.89 in the account. Work out the annual interest rate of the bank account. Give your answer as a percentage to 1 d.p.
The compound interest rate of the given information for which the annual rate of the bank account is = 3.9%.
What about compound interest?
Compound interest refers to the interest that is earned not only on the principal amount of a loan or investment but also on any interest that has been previously earned. In other words, it is the interest calculated on the initial principal and on the accumulated interest of previous periods. This compounding effect can result in significant growth over time, as the interest earned in each period is added to the principal, and the interest earned in subsequent periods is calculated on the new, larger principal amount. Compound interest is often used in long-term savings and investment accounts, such as retirement funds or fixed deposits, as it can result in a higher return than simple interest over time.
According to the given information:
In this case we know that;
⇒ A = [tex]P(1 + r)^n[/tex]
⇒ A = amount
⇒ P = principal
⇒ r = rate
⇒ n = number of years
⇒ 710.89 = 658.20[tex](1 + r)^2[/tex]
⇒ 710.89/658.20 = [tex](1 + r)^2[/tex]
⇒ 1.08 = [tex](1 + r)^2[/tex]
⇒ ln(1.08) =ln [tex](1 + r)^2[/tex]
⇒ 0.077 = 2ln[tex](1 + r)[/tex]
⇒ 0.077/2 = ln(1 + r)
⇒ ln[tex](1 + r)[/tex] = 0.0385
⇒ 1 + r = 1.039
⇒ r = 1.039 - 1
⇒ r = 0.039

Answer:
Adam's thinking is not correct.
When subtracting 10 from 708, we need to borrow 1 from the hundreds digit and add it to the tens digit. This will result in a new hundreds digit of 6 and a new tens digit of 9. The ones digit remains the same. Therefore, the correct answer would be 698.
Adam's answer is also 698, but his reasoning is incorrect. He thinks that both the tens and hundreds digits change, which is not the case. In reality, only the tens digit changes while the hundreds digit decreases by 1 due to the borrowing process.

Using ratios, we can find the average weight of the adult bear to be 250 pounds and the angles of the triangles are 10°, 75° and 95°.
What are ratios?Comparing two amounts of the same unit and calculating the ratio allows us to determine how much of one quantity is included in the other. Two categories of ratios exist. The part to whole ratio is one, and the part-to-part ratio is another. The part-to-part ratio illustrates the relationship between two separate entities or groupings.
In the question given,
Ratio between birth weight and adult weight of a bear is 3:1000.
The average birth weight as given here is = 12 ounces.
Now let the average adult weight be = x
According to the ratio,
12/x = 3/1000
⇒ 3x = 12000
⇒ x = 4000 ounces.
Now 16 ounces = 1 pounds
4000 ounces
= 4000/16
= 250 pounds.
The angles are in the ratio 2:15:19
Now we know all the angles sum up to 180°
Let the angle be = x.
The equation is as follows:
2x + 15x + 19x = 180
⇒ 36x = 180
⇒ x = 180/36
⇒ x = 5
So, all the angles of the triangles are, 10°, 75° and 95°.

what are coordinate ?In mathematics, a coordinate is a number or combination of numbers that represents the location of a point or object in space. Coordinates are frequently used to define a point or object's position in a certain coordinate system, such as the Cartesian or polar coordinate systems. In the Cartesian coordinate system, a point is found by its distance from the origin along the x-axis and its distance from the origin along the y-axis. These distances are represented by two integers, the x-coordinate and the y-coordinate. The point's location in the plane is specified by the two coordinates.
Using the distance formula, we can find the distances AC and CB:
[tex]AC = \sqrt((x - (-8))^2 + (y - 4)^2)\\CB = \sqrt((10 - x)^2 + (-2 - y)^2)\\[/tex]
Since AC:CB = 2:1, we have:
[tex]AC/CB = 2/1\sqrt((x - (-8))^2 + (y - 4)^2) / \sqrt((10 - x)^2 + (-2 - y)^2) = 2/1\\(x - (-8))^2 + (y - 4)^2 / ((10 - x)^2 + (-2 - y)^2) = 4\\(x - (-8))^2 + (y - 4)^2 = 4((10 - x)^2 + (-2 - y)^2)\\5x^2 + 5y^2 - 116x + 20y + 340 = 0\\(x - (-8))^2 + (y - 4)^2 = r^2\\(x - (-8))^2 + (y - 4)^2 / ((10 - x)^2 + (-2 - y)^2) = 4\\[/tex]

the angle has 4x and 6x what is the measurement of the angle
The sum of the measures of the two angles is 180 degrees, as they are angles of a straight line. The measure of the first angle is 4x = 72 degrees, and the measure of the second angle is 6x = 108 degrees.
What is angle ?
A measure of rotation of two crossing lines or planes in mathematics is called an angle. Angles are frequently defined as degrees or radians. Two lines or splines intersect at a location, known as the apex of the angle, to produce an angle. The edges of the angle are the two lines and line segments. According to its measurement, an angle can be categorized as: An acute angle is one that ranges from 0 to 90 degrees. Right arc: an angle that is 90 degrees in length. A measureable angle intermediate 90 and 180 degrees is referred to as an obtuse angle. 180 degree angle is referred to as a straight angle.
The sum of the measures of the two angles is 180 degrees, because they are angles of a straight line. Therefore:
4x + 6x = 180
Simplifying the left-hand side, we get:
10x = 180
Dividing both sides by 10, we obtain:
x = 18

Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options. The radius of the circle is 3 units. The center of the circle lies on the x-axis. The center of the circle lies on the y-axis. The standard form of the equation is (x – 1)² + y² = 3. The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
Answer:
To determine which statements are true, we can use the standard form of the equation of a circle:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center of the circle and r is the radius.
Using this form, we can rewrite the given equation as:
(x - 1)^2 + y^2 = 3^2 + 1^2 = 10
Comparing this to the standard form, we can see that the center of the circle is (1, 0), so the statement "The center of the circle lies on the x-axis" is true. However, the statement "The center of the circle lies on the y-axis" is false.
To find the radius, we can rearrange the equation as follows:
x^2 - 2x + y^2 = 8
Completing the square for x, we get:
(x - 1)^2 + y^2 = 9
This shows that the radius of the circle is 3, so the statement "The radius of the circle is 3 units" is true, as well as the statement "The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9."
Therefore, the three true statements are:
1.The radius of the circle is 3 units.
2.The center of the circle lies on the x-axis.
3.The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

Ella has an offer to buy an item with a sticker price of $12,300 by paying $420 a month for 36 months. What interest rate is Ella being offered?
Answer:
To calculate the interest rate, we can use the formula for the present value of an annuity:
PV = PMT x [(1 - (1 + r)^(-n)) / r]
where:
PV = present value
PMT = monthly payment
r = interest rate per period
n = number of periods
In this case, we have:
PV = $12,300 (the sticker price)
PMT = $420
n = 36 (36 months)
Substituting these values into the formula, we get:
12,300 = 420 x [(1 - (1 + r)^(-36)) / r]
Simplifying this equation algebraically is not possible, so we need to use numerical methods to solve for r. One way to do this is to use a financial calculator or spreadsheet program, which can find the interest rate that makes the equation true. Using Excel's RATE function, for example, we get:
=RATE(36,-420,12300)
This gives us an interest rate of approximately 3.33% per month or 39.96% per year.
Therefore, Ella is being offered an interest rate of 3.33% per month or 39.96% per year.

You want a1 for the geometric series that has r = 2/5, an = 120, and Sn = 3045.
Series relationsThe n-th term of the geometric series with first term a1 and common ratio r is ...
an = a1·r^(n-1)
The sum of the first n terms of the geometric series is ...
Sn = a1·(r^n -1)/(r -1)
ApplicationWe can use the expression for an to substitute for r^n in the sum equation:
[tex]a_n=a_1(r^n)(r^{-1})\\\\r^n=\dfrac{a_n}{a_1r^{-1}}=\dfrac{a_nr}{a_1}\\\\S_n=a_1\dfrac{r_n-1}{r-1}=a1\dfrac{\dfrac{a_nr}{a_1}-1}{r-1}\\\\S_n=\dfrac{a_nr-a_1}{r-1}\\\\a_1=a_nr-S_n(r-1)=a_nr+(1-r)S_n\\\\a_1=(120)\dfrac{2}{5}+(1-\dfrac{2}{5})(3045)=\dfrac{2\cdot120+3\cdot3045}{5}\\\\\boxed{a_1=1875}[/tex]

Additional comment
The sum is of the first four terms:
1875 +750 +300 +120 = 3045
We can also find this by working backward. The previous term is 5/2 times the current term. We need to find the terms that have a sum of 3045.
120 +300 +750 +1875 +4687.5 +...
Clearly, 5 terms is too many. The sum of the first 4 terms of the backward series is 3045, so we know n=4 and the first term is 1875—the last term of our 4-term backward series.

Write an equation to determine the length (l)(l)left parenthesis, l, right parenthesis of the rectangle.
The length of the rectangle is 10.5 units.
What is perimeter?
Perimeter is the distance of a two-dimensional shape. It is equal to the sum of the lengths of all the sides of the shape. The perimeter is measured in units, such as centimeters, meters, feet, or inches, depending on the unit of measurement used for the dimensions of the shape.
The perimeter of a rectangle is given by the formula:
P = 2l + 2w
where P is the perimeter, l is the length, and w is the width.
In this case, we know that the perimeter is 34 units, and the width is 6.5 units. So we can substitute these values into the formula and solve for the length:
34 = 2l + 2(6.5)
Simplifying, we get:
34 = 2l + 13
Subtracting 13 from both sides, we get:
21 = 2l
Dividing both sides by 2, we get:
l = 10.5
So the equation to determine the length of the rectangle is:
2l + 2w = P
Substituting the known values, we get:
2l + 2(6.5) = 34
Simplifying and solving for l, we get:
2l + 13 = 34
2l = 21
l = 10.5
Therefore, the length of the rectangle is 10.5 units.

Describe Decomposition of numbers?Decomposition of numbers involves breaking a number down into its constituent parts or smaller numbers that add up to the original number. This can be done in different ways depending on the purpose and context of the problem.
For example, one common way of decomposing a number is by place value. In this case, the number is broken down into its digits, which represent different powers of ten. For instance, the number 562 can be decomposed into 500 + 60 + 2.
Another way of decomposing numbers is by factoring. In this case, the number is expressed as a product of its factors. For example, the number 12 can be decomposed as 2 x 2 x 3.
Decomposing numbers is a useful skill in many areas of mathematics, including arithmetic, algebra, and geometry. It is often used to simplify problems, make computations easier, and facilitate further analysis.
To decompose 29 to make a new 10, we can break it into 9 and 20. Then, to decompose 14 to make a new 10, we can break it into 6 and 8.
So, we have:
29 + 14 = (9 + 20) + (6 + 8)
Now, we can regroup the numbers to make a new 10:
= (9 + 1) + (20 + 6) + 8
= 10 + 26 + 8

From inspection of the given right triangle, we can see that the interior angles are 45°, 45° and 90°. Therefore, this triangle is a 45-45-90 triangle.
A 45-45-90 triangle is a special right triangle where the measures of its sides are in the ratio 1 : 1 : √2. Therefore, the formula for the ratio of the sides is b: b : b√2 where:
b is the measure of the legs opposite the 45° angles.b√2 is the longest side (hypotenuse) opposite the right angle.We have been given the hypotenuse, so:
[tex]\implies b\sqrt{2}=5[/tex]
Solve for b:
[tex]\implies \dfrac{b\sqrt{2}}{\sqrt{2}}=\dfrac{5}{\sqrt{2}}[/tex]
[tex]\implies b=\dfrac{5}{\sqrt{2}}[/tex]
The side labelled "x" is one of the sides opposite the 45° angles, so:
[tex]\implies x=b[/tex]
Substitute the found value of b into the equation for x:
[tex]\implies x=\dfrac{5}{\sqrt{2}}[/tex]
[tex]\implies x=3.5355339...[/tex]
[tex]\implies x=3.5\;\sf(nearest\;tenth)[/tex]
Therefore, the length of side x to the nearest tenth is 3.5.

Lyla invests $2,500 into a savings account
which earns 5% per year. In 15 years, how
much will Lyla's investment be worth if interest
is compounded semiannually (twice a year)?
Round to the nearest dollar.
Answer:
We can use the formula for compound interest to find the future value of Lyla's investment:
A = P(1 + r/n)^(nt)
where A is the future value, P is the principal (initial investment), r is the annual interest rate as a decimal, n is the number of times interest is compounded per year, and t is the time in years.
Substituting the given values, we get:
A = $2,500(1 + 0.05/2)^(2*15)
Simplifying, we get:
A = $2,500(1.025)^30
Using a calculator, we get:
A ≈ $5,016.35
Therefore, Lyla's investment will be worth approximately $5,016.35 in 15 years if interest is compounded semiannually. Rounded to the nearest dollar, the answer is $5,016.
June is driving from Brookline, Massachusetts, to Brooklyn, New York. The cities are 200 miles apart. Pretend June lives in a world in which she encounters no traffic jams and can drive at a constant speed of 50 mph the entire way. The distance June has traveled, c, is a function of her driving time, t Write a formula that describes this function.
This function's definition is given by the formula [tex]c = 50t + 200[/tex].
What pace is it moving at?Consider how many individuals and gadgets will be utilizing the network at once as well as how it will be utilized before choosing the "optimal" speed for your home. As a general rule, anything that can connect many devices simultaneously and is above 200 Mbps is regarded as "fast" internet.
What would you define speed as?Speed, which is a scalar number, is the "speed at which an item is moving." The pace at which an item travels a distance may be referred of as its speed. A fast-moving item travels at a great velocity and completes a significant distance in a brief period of time.
[tex]y = mx + b[/tex]
Where [tex]y,x[/tex] are variables, m is the rate of change and [tex]b[/tex] is the y intercept.
Let [tex]c[/tex] represent the distance June has traveled after time [tex]t[/tex].
Since the cities are [tex]200[/tex]miles apart, hence [tex]b = 200[/tex]. Also the speed is [tex]50[/tex]mph, hence [tex]m = 50[/tex]:
[tex]c = 50t + 200[/tex]
The formula that describes this function is [tex]c = 50t + 200[/tex]

Solve the following quadratic by completing the square
f(x) = x^2 + 2x-12
The quadratic equation f(x) = x² + 2x - 12 can be rewritten as f(x) = (x + 1)²- 13 using the completing square method.
What is completing squares method?Completing the square is a strategy used in algebra to solve quadratic equations of the type ax² + bx + c = 0, where a, b, and c are constants and x is the variable. By converting the quadratic equation into a perfect square trinomial, the square roots of both sides of the equation may be used to quickly solve the problem. This is the core notion behind the completion of the square. The quadratic expression becomes a perfect square when we add and subtract a specific number from it to complete the square. Half of the x-term squared coefficient is equal to the sum of the numbers we add and remove.
The given function is f(x) = x² + 2x-12.
Now, group the x terms together:
f(x) = (x² + 2x) - 12
Between the parenthesis, add and remove the square of the x-half-coefficient: term's:
f(x) = (x² + 2x + (2/2)² - (2/2)²) - 12
f(x) = (x + 1)² - 1 - 12
f(x) = (x + 1)² - 13
Hence, the quadratic equation f(x) = x² + 2x - 12 can be rewritten as f(x) = (x + 1)² - 13.
