What’s the pattern of 1/2,2/4, &4/8?

Answer:

x = 70°

Y = 20°

Step-by-step explanation:

We Know

x + 20° = 90°

x = 70°

Y is the vertical angle to the 20° angle, meaning y must have the same measure as the 20° angle.

So, Y = 20°

Answer:

x=70

y=20

Step-by-step explanation:

We can see that y is a vertial angle and so it is 20 and x+20=90 wich means that x=70

Therefore, the balance after 3 years of continuous compounding at an annual interest rate of 3.1% is approximately $2,701.85.

Percent is a way of expressing a number as a fraction of 100. The word "percent" means "per hundred," so when we say something is, for example, 25%, we mean it is 25 out of 100, or 0.25 as a decimal. Percentages are often used to express ratios or proportions, such as in statistics, finance, and everyday life. Some common examples include: Interest rates: A bank might advertise a 5% annual interest rate on a savings account, which means that the account balance will increase by 5% (or 0.05) each year. Discounts: A store might offer a 20% discount on a product, which means that the price will be reduced by 20% (or 0.20) of the original price. Grades: A student might receive a grade of 85% on a test, which means that they answered 85 out of 100 questions correctly. Percentages can be converted to decimals or fractions, and vice versa, using simple arithmetic operations. For example, to convert a percentage to a decimal, divide by 100. To convert a decimal to a percentage, multiply by 100 and add a percent sign (%).

Here,

The formula for continuous compounding is:

[tex]A = Pe^{rt}[/tex]

where A is the ending balance, P is the principal amount, r is the annual interest rate (as a decimal), t is the time in years, and e is the mathematical constant approximately equal to 2.71828.

Plugging in the given values, we get:

A = 2340 * [tex]e^{0.031*3}[/tex]

According to the question we can conclude that expanding the garden will increase its area by 48 square feet.

Let's call the base of the original right triangle "b" and the height "h". The area of the right triangle is given by the formula:

Area = (1/2) * base * height

So we have:

16 = (1/2) * b * h

When we factor in a single of the variables, then obtain:

b * h = 32

Now, the new triangle will have twice the base and twice the height of the original triangle, so the new base will be 2b and the new height will be 2h. The area of the new triangle is given by the formula:

(Half) * Additional Base * Increased Height = New Area

Plugging in the new values, we get:

New area = (1/2) * 2b * 2h

Simplifying:

New area = 2bh

Now we need to find by how much the area has increased, which is the difference between the new area and the old area:

Area increase = Current area minus Old area.

Area increase = 2bh - 16

Substituting bh = 32, we get:

Area increase = 2(32) - 16

Area increase = 48

Therefore, expanding the garden will increase its area by 48 square feet.

He uses 3 1/4 cups to make dinner.

3 1/4 = 13/4

How many cups of rice does Jayden have left?

We Take

53/6 - 13/4 = 212/24 - 78/24 = 134/24 = 67/12

So, Jayden has  67/12 cups of rice left.

The value of the expression is 38 when z = 17.

Given that, an algebraic expression is described as 14 more than the product of 3 and the difference of z and 9.

First, we write the expression:

The difference of z and 9 means we subtract 9 from z. We then take this result and multiply it by 3.

Finally, we add 14 to the product of 3 and the difference of z and 9.

3(z - 9) + 14

Where z represents the value that we want to substitute into the expression.

Substituting z = 17, we get:

3(z - 9) + 14

3(17 - 9) + 14

3(8) + 14

24 + 14

STANDARD FORM is [tex]3x^2 + 24x + 32y + 192 = 0[/tex] ,parabola has a maximum point at its vertex, which is (2, -3).

to write the equation for the given parabola in standard form, we need to use the vertex form of the equation of a parabola, which is:

[tex]y = a(x - h)^2 + k[/tex]

where (h, k) is the vertex of the parabola and 'a' is the coefficient that determines the shape and direction of the parabola.

We know that the x-intercepts of the parabola are -2 and 6. This means that the parabola intersects the x-axis at these two points. Therefore, the roots of the quadratic equation are -2 and 6.

We also know that the y-intercept of the parabola is -48, which means that the point (0, -48) lies on the parabola.

Since the parabola is symmetric about the vertical line passing through its vertex, the x-coordinate of the vertex is the midpoint of the x-intercepts, which is (6 - 2)/2 = 2.

Therefore, the vertex of the parabola is (2, k), where k is the y-coordinate of the vertex.

Now we can use the vertex form

[tex]y = a(x - 2)^2 + k[/tex]

We need to determine the values of 'a' and 'k' to complete the equation.

Since the parabola passes through the point (0, -48), we can substitute x = 0 and y = -48 into the equation:

[tex]-48 = a(0 - 2)^2 + k[/tex]

-48 = 4a + k

Similarly, since the x-intercepts are -2 and 6, we can substitute x = -2 and x = 6 into the equation to get:

[tex]0 = a(-2 - 2)^2 + k[/tex]

0 = 16a + k

0 = a(6 - 2)^2 + k

0 = 16a + k

Solving these three equations for 'a' and 'k', we get:

a = -3/8 and k = -3

Substituting these values into the vertex form equation, we get:

[tex]y = (-3/8)(x - 2)^2 - 3[/tex]

Therefore, the equation for the parabola in standard form is:

[tex]3x^2 + 24x + 32y + 192 = 0[/tex]

This parabola has a maximum point at its vertex, which is (2, -3).

Point A rounded to the nearest whole Number is 35, and rounded to the nearest ten is 40.

Let's analyze the vertical number line and Point A:

1. The number line is labeled 30 to 40, with tick marks every one unit.
2. Point A is slightly above the tick mark 35.

Now, we need to round Point A to the nearest whole number and the nearest ten.

To round to the nearest whole number:
1. Observe the position of Point A on the number line.
2. Since Point A is slightly above 35, it's closer to 35 than 36.
3. Therefore, Point A rounded to the nearest whole number is 35.

To round to the nearest ten:
1. Observe the position of Point A (35) in relation to the tens (30 and 40) on the number line.
2. Since 35 is exactly halfway between 30 and 40, it is equidistant from both.
3. In this case, we round up to the next ten, which is 40.
4. Therefore, Point A rounded to the nearest ten is 40.

In summary, Point A rounded to the nearest whole number is 35, and rounded to the nearest ten is 40.

the composition of transformations that map ABCD to EHGF is a reflection over the y-axis followed by a translation by (4,7).

What is axis reflection ?

An axis reflection is a transformation in geometry that involves reflecting a point, a line, or an object across a given axis. In two dimensions, there are two axes of reflection: the x-axis and the y-axis.

When reflecting over the x-axis, all points stay in the same horizontal position but change their vertical position, so a point (x,y) is reflected to (x,-y).

When reflecting over the y-axis, all points stay in the same vertical position but change their horizontal position, so a point (x,y) is reflected to (-x,y).

Axis reflections can be used to transform geometric shapes such as polygons, circles, or lines. These transformations have important applications in various fields, including physics, engineering, computer graphics, and art.

To find the composition of transformations that map ABCD to EHGF, we first need to determine the individual transformations that are needed.

Reflecting over the y-axis will change the x-coordinates of the points, but leave the y-coordinates unchanged. So, to reflect over the y-axis, we negate the x-coordinates of the points.

The translation (x+4, y+7) will move each point 4 units to the right and 7 units up.

Therefore, the composition of transformations is:

Reflect over the y-axis by negating the x-coordinates:

A'(-2, 3), B'(-4, 2), C'(-4, 0), D'(-2, -1)

Translate by (4,7):

A''(2, 10), B''(0, 9), C''(0, 7), D''(2, 6)

Therefore, the composition of transformations that map ABCD to EHGF is a reflection over the y-axis followed by a translation by (4,7).

The newspaper's claim was incorrect, as the percent error of the prediction was 0.76%, which is greater than 2%.

It is the difference between the observed value and the true value, expressed as in percentage. It is used to quantify how accurately a given measurement, prediction or other value matches the true value.

The percent error of the prediction can be calculated using the following formula:

[(Predicted Price - Actual Price) / Actual Price] × 100.

For this problem, the percent error

= [(4.10 - 4.069) / 4.069] × 100

= 0.76%.

Therefore, the newspaper's claim was incorrect since the percent error did not fall within the specified 2%.
