Answer 1

Answer:

angle 1 = 100 degrees

angle 2 = 53 degrees

Step-by-step explanation:

diagonals of a rhombus bisect angles so angles 2 and 3 are both 53

angle 1 can be found by adding 37 and 53 and deducting that sum from 180

Sonya had 20 dollars to spend on 3 gifts. She spent 8 1 4 dollars on gift A and 4 4 5 dollars on gift B. How much money did she have left for gift C?

Answers

Answer:

6 19/20 dollars

Step-by-step explanation:

Sonya had 20 dollars to spend on 3 gifts.

She spent 8 1 4 dollars on gift A and 4 4 5 dollars on gift B.

Gift A + Gift B + Gift C = $20

Gift C = $20 - (Gift A + Gift B)

Gift A = $8 1/4

Gift B = $4 4/5

Hence:

The amount she had left for gift C is :

Gift C = $20 - ($8 1/4 + $ 4 4/5)

Gift C = $20 - $13 1/20

Gift C = $ 6 19/20

Martin is paid an hourly rate of d dollars per hour for the first 40 hours he works per week. He is paid one-and-a-half times his
hourly rate for each hour he works in excess of 40 hours per week.
If Martin was paid $770 for working 50 hours in one week, which equation can be used to calculate d, Martin's hourly rate of pay?

Answers

Answer:

40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.

Step-by-step explanation:

Given that:

Hourly rate = d

Earning to first 40 hours = 40d

Earning of more than 40 hours = 1.5d

Amount paid per week = $770

Hours worked = 50 hours

first 40 hours + 10 hours = total earned

40d + 10(1.5d) = 770

Hence,

40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.

Which equation best represents the line on

B.
-
A. y--3-4
y
-x-4
C. y ---4
D. y-r+4

Answers

Answer:

B. y=3/2x - 4

Step-by-step explanation:

As you see in the graph the y intercept was lying on -4 and you rise 3 time and run 2 time to get to your next point.

Write the equation of the line with the given slope and y Intercept.
m=0 b = -11

Answers

y=-11 As we input x and y in y=mx+b we know that slope is zero so the x drops therefore -11 remains as y-intercept and its parallel (-11,0)

Peter is folding brochures for his Dad's new company. After 1 hour, he has 330 brochures left to fold. After 4 hours, he only has 90 brochures left to fold.

(From the above statements you should be able to create two ordered pairs. I will create one for you..... (1,330). Now you create the other ordered pair and continue with the problem.)

Write an equation in slope-intercept form, y=mx+b, that represents the number of brochures Peter has left to fold, , after a given number of hours, x.

Answers

Answer:

y = -80x + 410

Step-by-step explanation:

(1,330) is the first point, the other point is (4,90)

m = y2 - y1/x2 - x1

m = 90 - 330/4 - 1

m = -240/3

m = -80/1

m = -80

y - y1 = m(x - x1)

y - 330 = -80(x - 1)

y - 330 = -80x + 80

y = -80x + 80 + 330

y = -80x + 410

26) One third of the students earned an A on the test. If 9 of the students earned an A, how many students are there in total?

Answers

There would be 27 students in total. You can find this by knowing that since 9 students got an a, and they make up 1/3 of the class, you should do 9(3) and that will give you 27. I hope I was able to help you understand better!

Answer:

Step-by-step explanation:

9 students = 1/3, 9 students = 1/2, 9 students = 1/3 so 9 x 3 =27

Find the Missing side length for #8

Answers

Answer:

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{LM}{QR}[/tex] = [tex]\frac{KL}{PQ}[/tex] , substitute values

[tex]\frac{x}{15}[/tex] = [tex]\frac{28}{21}[/tex] ( cross- multiply )

21x = 420 ( divide both sides by 21 )

x = 20 → A

Find the surface area of the pyramid to the nearest whole number.

Answers

Given:

A square base pyramid whose base length is 10 in. and height of triangular surface is 4 in.

To find:

The surface area of the pyramid to the nearest whole number.

Solution:

A square base pyramid contains square base with edge 10 in. and 4 congruent triangles with base 10 in. and height 4 in.

Area of a square is

[tex]A_1=(edge)^2[/tex]

[tex]A_1=(10)^2[/tex]

[tex]A_1=100[/tex]

So, area of square base is 100 sq. in.

Area of a triangle is

[tex]A_2=\dfrac{1}{2}\times base\times height[/tex]

[tex]A_2=\dfrac{1}{2}\times 10\times 4[/tex]

[tex]A_2=20[/tex]

So, area of each triangular surface is 20 sq. in.

Now, the total surface area of the pyramid is

Total area = Area of square base + Area of 4 congruent triangles.

[tex]A=A_1+4\times A_2[/tex]

[tex]A=100+4\times 20[/tex]

[tex]A=100+80[/tex]

[tex]A=180[/tex]

Therefore, the area of the pyramid is 180 sq. in.

What is the surface area?

Answers

Answer:

0.5 X 15 X 20 = 150m squared

150 X 2 = 300m squared (that's the two triangles done)

25 x 7 = 175m squared (front)

15 X 7 = 105m squared (base)

20 X 7 = 140m squared (back)

now add them all together

300 + 175 + 105 + 140 = 720

SA = 720cm squared

Answer:How do u find the surface area of a cube?

To determine the surface area of a cube, calculate the area of one of the square sides, then multiply by 6 because there are 6 sides. This is the same as solving using the formula SA = 6s2. If you are given the surface area, you can determine the side length by working backwards.
