Answer:
w = width
h = height
2(w+h) < 200
w + h < 100
since w = 36, then
36 + h < 100
h < 100 - 36
h < 64
Step-by-step explanation:
The perimeter of the rectangular picture frame can be calculated by the equation,
2h + 2w = P
where h and w are height and width , respectively. Substituting the known values and the condition for the inequality,
2h + 2(36 in) < 200
The inequality gives h as,
h < 64
Thus, the answer is letter A.
Answer:
Object will reach the max height in 10 seconds.
Max. height is 1817.
It will hit the ground in 20 seconds.
Step-by-step explanation:
In order to find the x value which makes the function take its greatest value, you need to take the derivative of the function and equalize the result to 0.
h'(t)=-12t+120=0
t=10
The object will reach its maximum height in 10 seconds.
h(10) (maximum height) = 6.10.10+120.10+17= 600+1200+17=1817
Considering this is a parabola, time in total is two times more than the time passed until reaching the max. height.
10.2=20
Answer:
Step-by-step explanation:
y = 3x+4 and y = x-2
3x+4 = x-2
2x+4 = -2
2x = -6
x = -3
y = -3 -2 = -5
Each 7 inches of the tv are equal to one inch of the phone. Therefore Divide 56 by 7 you get 8 56/7=8
Answer:
Scale = 5ft/in
Step-by-step explanation:
Given
Scale Measurement = 6in.
Actual Width = 30ft
Required
Scale Ratio.
The scale ratio can be calculated as thus:
Scale Ratio = Actual Measurements ÷ Scale Measurements
Scale Ratio = 30ft ÷ 6in
Scale Ratio = 30ft/6in
Simplify to lowest terms
Scale Ratio = 5 ft/1 in
Scale Ratio = 5ft/in
This can also be represented as follows;
Scale Ratio = 5ft : 1in
This means that 5 ft on the actual measurements is represented by 1inch on the scale.
