Answer:
7
Step-by-step explanation:
48 * 56 = 3 * 7 * 2^ c
2688 = 21 * 2 ^ c
2688 / 21 = 2^c
128 = 2^c
2^7 = 2^c
c = 7
Explaination: 48•56=2688, 21+2665

The width of a triangle is represented by 5 +2y. The length is twice as long as the width. What is the perimeter of the rectangle? Select all correct expressions.
Answers
Answer:
6(5+2y)
Step-by-step explanation:
We have width = w = 5+2y
L = length of the rectangle
Length has been give to be 2 x width
Width = w
So l = 2w
Perimeter of a rectangle = 2(l+w)
Since l = 2w, we have
2(2w+w)
= 2(3w)
= 6w
So since we already know w = 5+2y
We put this value into 6w
Then we will have this expression:
P = 6(5+2y)

If the measure of angle 2 is 92 degrees and the measure of angle 4 is (one-half x) degrees, what is the value of x?
Answers
Answer: x = 184°
Step-by-step explanation: As we can see in the figure below, angles 2 and 4 are Vertical Angles, i.e., they are angles opposite each other when two lines cross. Vertical angles are always congruent.
Then,
m∠2 = m∠4
[tex]92=x.(\frac{1}{2})[/tex]
[tex]92=\frac{x}{2}[/tex]
Value of x is
[tex]x=92(2)[/tex]
x = 184
The value of x is 184°.

= (-9 - -4)/(-3 - 22)
= (-9+4)/(-25)
= -5/ -25

A piece of rope is 15.6 meters long. It is cut into 16 equal pieces. How long is each piece? Round your answer to the nearest tenth.
Answers
Answer:
1 m
Step-by-step explanation:
Given thta,
Length of a piece of rope = 15.6 m
It is cut into 16 equal pieces.
We need to find the length of each piece of rope.
Let the length of each piece is y m.
ATQ,
16 y = 15.6
⇒ y = 0.975
or
⇒ y = 1 m
Hence, the length of each piece is 1 m.

25 yd
37 yd
Answers
Answer:
27.3 yards
Step-by-step explanation:
Since this triangle is a right triangle, this can be solved using the equation:
a^2 + b^2 = c^2
c^2 is the side opposite to the right angle (37)
So, you need to change the equation to where it is set equal to b^2.
Subtract a^2 on both sides.
b^2 = c^2 - a^2
Now, plug in the numbers you have.
b^2 = 37^2 - 25^2
Simplify.
b^2 = 1369 - 625
b^2 = 744
Now, to find b, take the square root of 744.
√744 = 27.3
