Answer: m∠F=67°
Step-by-step explanation:
Given the right triangle FHG and the lengths of all its sides:
You can calculate the measure of the angle identified as m∠F with:
Where the opposite side is 12, the adjacent side is 5 and the angle is m∠F.
Then, substituting values into :
To the nearest degree:
m∠F=67°
1.) 1 3/4 || 14/8 || 1 21/28
2.) 21/36 || 140/240
3.) 3 || 1 24/12 || 75/25 ||2 15/15
Answer:
Surface area of 5 sides = 51.2 cm²
Step-by-step explanation:
Given:
Side of cube = 3.2 cm
Find:
Surface area of 5 sides
Computation:
Surface area of 5 sides = Surface area of cube - Surface area 1 side
Surface area of 5 sides = 6a² - a²
Surface area of 5 sides = 6(3.2)² - (3.2)²
Surface area of 5 sides = 6(10.24) - 10.24
Surface area of 5 sides = 6a² - a²
Surface area of 5 sides = 61.44 - 10.24
Surface area of 5 sides = 51.2 cm²
Answer:
60mph
Step-by-step explanation:
Let d be the distance. Let v be the speed of car a. That means the speed of car b is v + 15. Now we can set up 2 equations using the v = d/t:
Car a: v = d / 2 --> d = 2v
Car b: v + 15 = d / 1.5
We can solve for v by substituting the first equation (rearranged to isolate d) into the second:
v + 15 = 2v / 1.5
1.5v + 22.5 = 2v
0.5v = 22.5
v = 45
We're looking for the speed of car b, which was v + 15 = 45 + 15 = 60.
A. The graph is decreasing. For every time the x gets bigger the y value decreases.
