Answer:
(set up a ratio)
54/x = 18/100
(cross multiply)
18x = 5400
(solve for x)
x = 300 miles
Step-by-step explanation:
Answer:
E. cot(90° -θ)
Step-by-step explanation:
The "cofunction" is named by adding or deleting the "co" in front of the function name. The cofunction for tangent is <em>cotangent</em>.
The tangent of an angle is the cotangent of the complement of the angle:
tan(θ) = cot(90° -θ)
2y = 12 - 5x
y = 6 - 5/2x
2 = -5/2(-3) + b
2 = 15/2 + b
2 - 15/2 = b
b = -11/2
y = 15/2x - 11/2
Answer:
32 units squared
Step-by-step explanation:
This is kind of a weird shape, so split it into smaller shapes, in this case two triangles and a rectangle.
Both of the triangles have a base of 8 and a height of 2. Multiply the base and the height together, then divide by 2. 8*2/2 equals 8, so the area of each triangle is 8.
For the rectangle, the length is 2, and the width is 8. Multiply the length and the width together to get 16.
Finally, add the areas of all those smaller shapes together to get the area of the whole shape, 32 units squared.
Answer:
The number is 30
Step-by-step explanation:
Let x be the number
2/3 x = 20
Multiply each side by 3/2 to isolate x
3/2 *2/3x = 20*3/2
x = 30
