Answer:
5/6
Step-by-step explanation:
We assume you want the ratio ...
(20 hr)/(24 hr) = (4·5)/(4·6) = 5/6 . . . . . factors of 4 and hours cancel
The ratio is 5/6.
Step-by-step explanation:
<h3>Part A</h3>
<u>Circumference formula:</u>
<u>Find π:</u>
- 25.12 = 8π ⇒ π = 25.12/8 ⇒ π = 3.14
- 9.42 = 3π ⇒ π = 9.42/3 ⇒ π = 3.14
<h3>Part B</h3>
<u>Area formula:</u>
<u>Find π:</u>
- 50.24 = π*8²/4 ⇒ 50.24 = 16π ⇒ π = 50.24/16 ⇒ π = 3.14
- 7.065 = π*3²/4 ⇒ 7.065 = 9π/4 ⇒ π = 4*7.065/9 ⇒ π = 3.14
<h3>Part C</h3>
- The value of π is same - 3.14 from each case we have
Y= 6/5x + 2
If you substitute the points (5,8) you get:
8 = 6/5 × 5 + 2
8 = 6 + 2
Answer:
48 inches
Step-by-step explanation:
38+10=48
48 inches
<u>Answer:</u>
(x, y) = (-2, 2)
<u>Step-by-step explanation:</u>
We are given the following two equations which we are to solve using the substitution method:
--- (1)
--- (2)
From equation (1):
Substituting this value of x in (2) to get:
![x = [tex]x - 2y = -6\\\\(y-4)-2y=-6\\\\-y=-6+4\\\\-y=-2](https://tex.z-dn.net/?f=x%20%3D%20%5Btex%5Dx%20-%202y%20%3D%20-6%5C%5C%5C%5C%28y-4%29-2y%3D-6%5C%5C%5C%5C-y%3D-6%2B4%5C%5C%5C%5C-y%3D-2)
[/tex]
y = 2
Substituting the value of y in (1) to get x:
x = -2
Therefore, (x, y) = (-2, 2).
