Answer:

The cost is $45 per hour.

Step-by-step explanation:

(h = hours)

1. The equation is 4.5h + 155 = 357.5.

2. Subtract 155 from both sides of the equal sign. The equation is 4.5h = 202.5.

3. Divide both sides by 4.5. The answer is h = 45.

Answer:

The answer is 10

Step-by-step explanation:

You will want to do 1/2B×h

Which is 1/2×4×5

Answer: Angles 4 and 5

Step-by-step explanation:

Supplementary angles are angles that add up to 180. The only angle pairs the add up to 180 (you can tell by seeing if two angles are the only two on a straight line) are angles 4 and 5, and angles 3 and 4. Angles 3 and 4 isn’t an option, so it’s 4 and 5.

Answer:

i believe that its angle 4 and 5 since they would sum up to 180 degrees

Step-by-step explanation:

When the numerator and denominator is same the answer will be always 1

For example:

[tex]\ \dfrac{3}{3} }[/tex], Here the numerator(3) and denominator(3) is same and equals to 1.

Radical example:

[tex]\ \dfrac{\sqrt{4} }{\sqrt{4} } }[/tex], Here the numerator(√4) and denominator(√4) is same and equals to 1.

Algebra example:

[tex]\dfrac{pq^2}{q^2p}[/tex] ,Here the numerator(pq²) and denominator(q²p) is same and equals to 1.

Answer:

The ~ numerator ~ represents the total number of parts taken into account. Now the ~ denominator ~ represents the total number of equal parts in a fraction!

Answer:

b = 33.9925 whatever unit is required

Step-by-step explanation:

Sides:

a = 66 m

b = 33.9925 m

c = 56.573 m

Angles:

A = 90 °

B = 31 °

C = 59 °

Other:

P = 156.566 m

s = 78.2828 m

K = 961.53 m2

r = 12.2828 m

R = 33 m

Agenda:

C = angle C

a = side a

b = side b

c = side c

P = perimeter

s = semi-perimeter

K = area

r = radius of inscribed circle

R = radius of circumscribed circle

Formula: AAS is Angle, Angle, Side

Given the size of 2 angles and 1 side opposite one of the given angles, you can calculate the sizes of the remaining 1 angle and 2 sides.

Use the Sum of Angles Rule to find the other angle, then

use The Law of Sines to solve for each of the other two sides.

The production cost is an illustration of a quadratic function

The equation of the production cost is [tex]y = ax^2 + bx - c[/tex]

From the complete question, we have the following parameters:

Using the instructions in the complete question, the equation of the production cost would be:

[tex]y = ax^2 + bx -c[/tex]

Hence, the production cost is [tex]y = ax^2 + bx - c[/tex]

When the production cost is less than 123,505;

The equation becomes

[tex]ax^2 + bx - c < 123,505[/tex]

The solution to the given algebraic equation is [tex]\mathbf{z = \dfrac{59+pd}{(p+2)}}[/tex]

Algebraic equations are mathematical expressions with variables, coefficients, and arithmetic operations. To solve algebraic expressions with two or more variables, the required variable to be solved must be the subject of the formula:

From the given information, we have:

[tex]\mathbf{-p\cdot(d+z) = -2z+59}[/tex]

-pd +pz = -2z + 59

pz + 2z = 59 + pd

z(p+2) = 59 + pd

In a triangle, the 3 angles add up to 180 degrees

Using the probability concept, it is found that an employee is more likely to choose swimming, with a 0.4236 = 42.36% probability, compared to a 0.3073 = 30.73% probability for playing games.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

For playing games, the probability is:

p = 169/550 = 0.3073.

For swimming, the probability is:

p = 233/550 = 0.4236.

Hence, an employee is more likely to choose swimming, with a 0.4236 = 42.36% probability, compared to a 0.3073 = 30.73% probability for playing games.

Answer:

feets of green fabric - 2feets = answer

Step-by-step explanation:

the inch of the total fabric wasn't given but the path given was that given to her sister

being 24inch

we are supposed to turn the inch to feet to find the answer

so, if

1 inch = 1 feets

12

therefore,

24inch = 1\12 * 24 = 2

let total feet of the fabric = f and

let part left of the fabric = p

therefore, p = f - 2

where p = part left

f = total fabric

This is because y is a factor of 5y and it's also a factor of y^2 = y*y

The total fabric Morgan needs to cover the cushions will be 19.64 square feet.

It is given that each cushion has a circumference of 7.85 feet.

It is known that the circumference of a circle = 2πr, where 'r' is the radius of the circle.

2πr = 7.85

r = 1.25

area of a circle is πr².

now, we can calculate the area = π× 1.25² = 4.91 square feet

since each circular cushion has two circular faces so the total number of faces Morgan needs to cover will be 4.

Therefore, the total fabric needed= 4×4.91 = 19.64 square feet.

This is Linda's commission

Answer:

60

Step-by-step explanation:

100% of the num is 40

150%=1.5

So multiply 40 by 1.5

=60

Other way (confusing)

50x3=150

20x3=60

The required 150% of the number is 60.

Given that,
Kai knows that 50% of a number is 20, how could he use the information to determine what 150% of the number is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

the percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Let the number be x,
It's 50 % is 20. i.e.
50% of  x = 20
50 / 100 * x = 20
x / 2 = 20    (50 / 100 = 1 / 2)
x = 40

Now its 150%
= 150% of 40
= 150 / 100 * 40
= 15 / 10 * 40
= 15 * 4
= 60

Thus, the required 150% of the number is 60.
