Answer 1
Answer:

Answer:

7)   40

8)   23

9)   63

Step-by-step explanation:

180 degrees in a triangle.  Add the 2 degrees they give you, and then subtract that from 180 to find the missing angle.

82 + 58 = 140    180 - 140 = 40

115 + 42 = 157    180 - 157 = 23

27 + 90 = 117     180 - 117 = 63

Hope this helps.

Answer 2
Answer:

Answer:

7=40, 8=23, and 9=63

Step-by-step explanation:

The key info to solve is that in a triangle there are 180 degrees

7) we add 82 and 58 and then subtract the total from 180 to find x

=82 + 58 = 140, and 180 - 140 = 40, so 40=x

We do the same for the rest

115 + 42 = 157, and 180 - 157 = 23, so 23=x

Wait whats that square in the triangle? It represents 90 degrees, a right angle!

so, 27 + 90(right angle) = 117, and 180 - 117 = 63, so 63=x

Answers

Here is an example:
Distributive property of division: (a + b) : c = a : c + b : c

96 : 6 = (90 + 6) : 6 = 90 : 6 + 6 : 6 = (60 + 30) : 6 + 1
= 60 : 6 + 30 : 6 + 1 = 10 + 5 + 1 = 16

The length of a rectangle is twice its width. The perimeter of the rectangle is no more than 174 cm. What is the greatest possible value for the width? (a) Write an inequality to model the problem. Explain why the inequality models the problem.
(b) Solve the inequality. Show your work.
(c) Answer the question.

Answers

a.2x+4x≤174 or y+x≤174 or x≤174
This is because x stands the width and that the perimeter.
b. 6x≤174
x≤29
c. The greatest possible value is 29. 

Tim is designing a logo. The logo is a polygon. Whose shape is a square attached to an equilateral triangle. The square and the equilateral triangle. The square and equilateral have side lengths of 2 centimeters, and the equilateral triangle has a height of about 1.7 cm. Find the area of the logo.

Answers

Given:
2 shapes : square and equilateral triangle
side length = 2 cm
height of equilateral triangle = 1.7 cm

Equilateral triangle means that all sides are of equal measurement.

Area of a Square = a² ⇒ (2cm)² = 4cm²
Area of an equilateral triangle = √3/4 * a² 
Area of an equilateral triangle = √3/4 * (2cm)² = 0.43 * 4cm² = 1.72 cm²

Area of the logo = 4 cm² + 1.72 cm² = 5.72 cm²

a cardboard box is open at one end and is shaped like a square prism missing one of its square bases. the volume of the prism is 810 cubic inches and its height is 10 inches. what is the length of each side of the base? how much cardboard is used for the box?

Answers

The correct answer for the question that is being presented above is this one: "9 inches; 441 in^2"

The volume of a square prism is
Volume = s^3 = lwh

Given that the volume is 810 in^3 and the height is 10 inches
810 = 10 * s^2
81 = s^2
s = 9 inches

So, the length of each side of the base is 9 inches
Then, the total area used in order to make a cardboard is that,
= 9^2 + 4 ( 10*9)
= 81 + 4(90)
= 81 + 360
= 441 square inches.

A CD makes 581/2 revolutions in 2/4 min.
Complete the unit rate.

Answers

In 2/4 minutes the number ofrevolutions a CD makes = 58 ½                                                                                       = 117/2
Then
In 1 minute the number ofrevolutions the CD will make = [(117/2)/(2/4) ] * 1                                                                                        =(117 * 4)/(2 * 2)                                                                                        = 117
So it can seen that the CD revolves at the rate of 117 revolutions per minute. I hope this is the answer you were looking for. The procedure for solving this problem is easy for you to understand i hope.

A CD makes 58 1/2 revolutions in 1/2 minutes.

A CD makes 58.5 revolutions in 0.5 minutes.

Multiply both numbers by 2.

A CD makes 117 revolution in 1 minute.
