Answer:
Θ ≈ 67.38°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosΘ = 
= 
= 
, then
Θ = 
( ) ≈ 67.38° ( to 2 dec. places )
Answer:
C. 8 miles per hour
Step-by-step explanation:
1/24th of an hour is 2.5 minutes, taking Diego 2.5 minutes to ride 1/3rd of a mile
2.5 x 3 (to signify how long it would take Diego to ride a mile) = 7.5 minutes
60 divided by 7.5 = 8
<em>Therefore, Diego's speed in MPH is </em><em>8.</em>
The answer is 10.6 cubic inches.
The formula for a volume of the cone is V = 1/3 π r² h,
where:
V - the volume of the cone,
<span>r - radius of the cone base,
</span>h - height of the cone.
It is given:
h = 4.5 in
r = 1.5 in.
π = 3.14
If:
<span>V = 1/3 π r² h,
</span>Then:
V = 1/3 × 3.14 × (1.5 in)² × 4.5 in
V = 1/3 × 3.14 × 2.25 × 4.5 in³
V = 10.6 in³
Therefore, Judy's sugar cone can hold 10.6 <span> in³.</span>
The answer to this sum is negative seven
