Answer:
1.12 pounds
Step-by-step explanation:
3.5 - 2.38 = 1.12
Answer:
56°
Step-by-step explanation:
Because the two lines are parallel, the corresponding angles are equal. The two corresponding ∠s are ∠A and ∠B. ∠A=∠B
∠A=4x
∠B=2(x+14)
4x = 2 (x+14)
the right side requires the distributive property
a) 4x = 2x+28
2x = 28
x = 14
b) now plug in x for both ∠s to find ∠A and ∠B
∠A = 4x = 4(14) = 56°
∠B = 2(x+14) = 2(14+14) = 2(28) = 56°
I just did both angles to show that they are equal and it is a way to check your work

Answer:
7
Step-by-step explanation:
the legs of a 45°- 45°- 90° triangle are congruent , then
one leg = 7
the other leg = 7
The answer is 250 cm³
We need to calculate V = Vr - Vp
V - the <span>volume of the space outside the pyramid but inside the prism
Vr - the volume of the rectangular prism.
</span>Vp - the volume of the pyramid<span>
Vr = w * l * h
w = l = 5 cm
h1 = 12 cm
Vr = 5 * 5 * 12 = 300 cm</span>³<span>
Vp = w * l * h / 3
w = l = 5 cm
h2 = h1/2 = 12/2 = 6 cm
Vp = 5 * 5 * 6 / 3 = 50 cm</span>³
V = Vr - Vp = 300 cm³ - 50 cm³ = 250 cm³
