Answer:
4(2x2-5y2)(2x2+5y2)
Step-by-step explanation:
Answer:
B) 20°
Step-by-step explanation:
The top half of the circle is equal to 180°...
13x + 3x + 2x = 180°
18x = 180°
x = 10°
Angle EOD is the opposite angle of 2x
2 (10) = 20°
Answer:
C
Step-by-step explanation:
Answer:115.4685yd^3
Step-by-step explanation:
Volume of cone=1/3πr2h
V=1/3×3.142×3.5yd×3.5yd×9yd
V=115.4685yd^3
Answer:
The answer is 18 cm
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- A force of 100 newtons stretches a spring 5 cm
<h3><u>To </u><u>Find</u>;</h3>
- If a force of 360 newtons then how much a spring will be stretches
Now, We need to write a proportion
Here,
Force₁ = 100 N
Length₁ = 5 cm
Force₂ = 360 N
Length₂ = x cm
Now,
Force₁ ÷ Length₁ = Force₂ ÷ Length₂
100/5 = 360/x
100x = 360 × 5
100x/100 = 360 × 5/100
x = 18 cm
Thus, If a force of 360 newtons then 18 cm a spring will be stretches.
