Answer:
<u>∠J = 31.06°</u>
Step-by-step explanation:
Taking the inverse sin function :
- sin ∠J = 1.6/3.1
- J = sin⁻¹ (0.516)
- <u>∠J = 31.06°</u>
A
to calculate the slope m , use the ' gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (5, 4)
m = 
= 
→ A
Answer:
The number of dimes is represented by x = 90
Step-by-step explanation:
Given that:
The number of dimes is represented by x
Number of quarters = 6 + 2x
Total number of coins in the bag = 276
To find x, we have:
x + 6 + 2x = 276
3x + 6 = 276
3x = 276 - 6
3x = 270
x = 270/3
x = 90
Answer:
-64 1/3 is the simplest form
Step-by-step explanation:
<h2>
Answer: C. 72 in.</h2>
Step-by-step explanation:
- Since the perimeter is 22, take out 10, or (5 × 2) to get 12
- Now divide 12 by 2 to get 6.
- Since the answer is in inches, multiply by 12 to get 72 inches.
Proof:
P = 2L + 2W
22 = 2(5) + 2(6)
22 = 10 + 12
22 = 22
