Answer:

Step-by-step explanation:

We are interested in finding out the missing angles of the rhombus . Some properties of rhombus that needs to be kept in mind are ,

[tex]\implies z = 80^o \\[/tex]

[tex]\implies x = y \\[/tex]

Now since the opposite sides are parallel, the sum of co interior angles would be 180° .

Here x and 80° are co interior angles. So their sum would be 180° . Hence,

[tex]\implies x + 80^o = 180^o \\[/tex]

[tex]\implies x = 180^o - 80^o \\[/tex]

[tex]\implies x = 100^o\\[/tex]

Now since x and y were equal , therefore,

[tex]\implies y = 100^o \\[/tex]

Therefore the value of x is 100° , z is 80° and y is 100° .

The angles of the triangle will be 5 °, 45 °, and 130 °.

The triangle is a two-dimensional geometric object with three straight sides and three angles. The lengths of the triangle's three sides can differ from the third side (isosceles triangle), be equal (equilateral triangle), or be any combination of the three (scalene triangle).

The sum of the angles in a triangle is always 180 degrees; the opposite angle of the longest side is the largest, and the opposite angle of the shortest side is the smallest.

Now,

Let x be the common factor that multiplies the ratio of 1:9:26. Then, the measures of the angles can be expressed as x, 9x, and 26x.

Since the sum of the angles in a triangle is always 180 degrees, we can set up an equation:

x + 9x + 26x = 180°

Simplifying the equation, we get:

36x = 180

Dividing both sides by 36, we get:

x = 5

Therefore, the measures of the angles are:

x = 5 degrees (the smallest angle)

9x = 45 degrees

26x = 130 degrees (the largest angle)

So the angles of the triangle are 5 degrees, 45 degrees, and 130 degrees.

Answer:

Step-by-step explanation:

Let's use the following variables:

Let F be the number of sections of Finite Math

Let A be the number of sections of Applied Calculus

Let C be the number of sections of Computer Methods

We can create a system of equations based on the given information:

F + A + C = 7 (the college wishes to offer a total of seven sections)

40F + 60A + 290C = 298000 (the college wishes to bring in $298,000 in revenues)

40F + 40A + 10C = 220 (the college wishes to accommodate 220 students)

We can solve this system of equations using any method we prefer. Here's one possible way:

Multiply the third equation by 10 to get:

400F + 400A + 100C = 2200

Subtract the third equation from the second equation to eliminate C:

20A + 280C = 76000

Multiply the first equation by 40 and subtract it from the previous equation to eliminate A:

240C = 76000 - 1600

Solve for C:

C = 290

Substitute C = 290 into the third equation to solve for F:

40F + 40A + 10(290) = 220

40F + 40A = -2680

F + A = -67

Substitute C = 290 and F + A = -67 into the first equation to solve for A:

A = 10

Substitute A = 10 and C = 290 into the first equation to solve for F:

F = -3

We have a problem here: we obtained a negative number of sections for Finite Math, which is impossible. This means that the original system of equations is inconsistent, and there is no solution that satisfies all the requirements.

Therefore, the college cannot offer the desired number of sections while accommodating the desired number of students and revenue. Some adjustments need to be made, such as changing the number of students per section or the tuition fees.

Answer: Krysti's mistake was ordering only 12 small T-shirts when she should have ordered more. To figure out how many small T-shirts she should have ordered, we can start by finding out how many classmates wanted small T-shirts:

60% of 25 classmates = 0.60 x 25 = 15 classmates

So, 15 classmates wanted small T-shirts. If Krysti had ordered one small T-shirt for each of these classmates, she would have needed 15 small T-shirts. However, Krysti only ordered 12 small T-shirts, which means she is short by 3 shirts.

To avoid this mistake, Krysti should have double-checked her calculations and made sure that the number of small T-shirts she ordered matched the number of classmates who wanted small T-shirts.

Answer:333

Step-by-step explanation:53533535

Answer:

To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where A is the amount of money accumulated, P is the principal (initial) amount, r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the number of years.

In this problem, we want to find the principal amount P that will accumulate to $12,000 in 3 years at an annual interest rate of 6% compounded monthly. First, we need to convert the annual interest rate to a monthly rate:

r = 0.06/12 = 0.005

Next, we can substitute the given values into the formula and solve for P:

12,000 = P(1 + 0.005/12)^(12*3)

12,000 = P(1.005)^36

P = 12,000/(1.005)^36

P ≈ $9,883.86

Therefore, the amount of money that should be deposited today is approximately $9,883.86.

Answer:

x = ± √((y + 2)/4)

Step-by-step explanation:

To find the inverse of a function, we need to solve for x in terms of y.

Steps to find the inverse of y = 4x^2 - 2:

Replace y with x and x with y:

x = 4y^2 - 2

Solve for y:

x + 2 = 4y^2

(x + 2)/4 = y^2

± √((x + 2)/4) = y

Note that we have a ± sign because the square root of a positive number can have two values, one positive and one negative.

Therefore, the inverse of y = 4x^2 - 2 is:

x = ± √((y + 2)/4)

Answer:

y=±([tex]\sqrt{x+2}/2[/tex])

Because of the isosceles triangle.

The triangle whose two sides are equal length is called an isosceles triangle. The third side, known as the base, may or may not be a different length from the other two sides. An isosceles triangle also has two angles that are equal in measure, which are opposite the two equal sides.

Given that in ΔMQN: MQ=MN,

therefore, ∠MQP=60°=∠MNO (isosceles triangle )

also given in ΔMPO: MP=MO,

therefore, ∠MPO=80°=∠MOP (isosceles triangle )

For the straight line PON,

∠POM + ∠MON = 180° (straight line angle)

The theorem that justifies the similarity of the two triangles is given as follows:

A: AA.

The Angle-Angle (AA) Congruence Theorem states that if two pairs of corresponding angles are congruent, then the triangles are similar.

In other words, if two angles of one triangle are equal in measure to two angles of another triangle, then the third angle in each triangle must also be equal in measure, and the two triangles are therefore congruent.

The two pairs of corresponding angles that are congruent in this problem are given as follows:

Hence the third angle will also have the same measure for both triangles.

The minimum clearance required for safety of fitting 95% of men is approximately 18.7 inches.

What is percentage ?

Percentage is a way of expressing a proportion or a ratio as a fraction of 100. It is often represented by the symbol % and is used to compare values, make comparisons, and analyze data. For example, if there are 25 red marbles and 75 green marbles in a jar, the percentage of red marbles is 25% (25/100), while the percentage of green marbles is 75% (75/100). Percentages are commonly used in many fields, including finance, business, statistics, and science.

To determine the minimum clearance required for safety of fitting 95% of men, we need to find the value of the sitting knee height at the 95th percentile for men.

Using the formula for a normal distribution, we can calculate that the sitting knee height at the 95th percentile for men is approximately 23.2 inches.

Therefore, the minimum clearance required for safety of fitting 95% of men would be the difference between the sitting knee height at the 95th percentile for men (23.2 inches) and the height of the work table.

Therefore, the minimum clearance required for safety of fitting 95% of men is approximately 18.7 inches.

Therefore, the scale factor used in the drawing is 4000/3.

In mathematics, a factor refers to a number or algebraic expression that divides another number or expression without leaving a remainder. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12, because each of these numbers can be multiplied by another whole number to produce 12 (1 × 12, 2 × 6, 3 × 4). Factors play an important role in many areas of mathematics, including algebra, number theory, and geometry, and are used to simplify expressions, solve equations, and factorize polynomials.

Given by the question.

The scale factor is the ratio of the length of an object on the drawing to the actual length of the object.

Since 6 millimeters on the drawing represents 8 meters in reality, the scale factor can be expressed as:

Scale factor = Actual length / Length on drawing

Scale factor = 8 meters / (6 millimeters)

To simplify this fraction, we need to convert meters to millimeters by multiplying by 1000:

Scale factor = (8 meters * 1000) / 6 millimeters

Scale factor = 8000 / 6

Answer:

Cindy's time was 5 2/5 minutes, or 5.4 minutes to the nearest tenth.

Step-by-step explanation:

To find Cindy's time, we need to use the information given about the total time and the times of the other three runners.

Let's first convert all the times to fractions of a minute:

Barbara: 3 3/10 = 3 + 3/10 = 3.3 minutes

Donna: 2 4/5 = 2 + 4/5 = 2.8 minutes

Cindy: x minutes

Nicole: 2 1/10 = 2 + 1/10 = 2.1 minutes

Now, we can set up an equation to represent the total time of the team:

Barbara's time + Donna's time + Cindy's time + Nicole's time = 11 3/5 minutes

Substituting the values we know:

3.3 + 2.8 + x + 2.1 = 11 3/5

Simplifying and converting mixed numbers to fractions:

8/5 + 14/5 + x + 11/5 = 116/10 + 3/5

Multiplying both sides by 10 to eliminate the denominators:

16 + 28 + 10x + 22 = 116 + 6

Simplifying:

10x = 54

Dividing by 10:

x = 5.4

Therefore, Cindy's time was 5 2/5 minutes, or 5.4 minutes to the nearest tenth.
