Answer:
125
Step-by-step explanation:
divide both sides of the equation by 0.8
0.8÷0.8=0.8÷100
any expression divided by 1 is itself
x=100÷0.8
divide the numbers
100÷0.8=125
125 is your answer
Answer:
Step-by-step explanation:
Answer:
The answer is 0.2mile
Step-by-step explanation:
The vertical height of the building, which is 630ft, is opposite the angle of elevation (30°).
While the horizontal distance to the tower is adjacent to the building. So, we take the tangent of the angle of elevation in terms of this unknown distance (x) and the vertical height.
So,
Tangent = opposite ÷ adjacent
Tan30° = 630ft ÷ x
x = 630ft ÷ tan30°
x = 1091.192ft
But,
1 mile = 5,280ft
1091.192ft = (1/5280) x 1091.192
= 0.2mile
Answer:length =7⅓
Width =14⅔
Step-by-step explanation:
Take length as x
And 2x as width
Perimeter as 44
Formula to get perimeter of a rectangle is 2l+2w
X+x+2x+2x=44
6×=44
X=7⅓
Length =x and x = 7⅓ so width =7⅓ while width =14⅔
