Answer:
find the area of the base which is as circle
Base area = pi * R^2 = 3.14 * 400 = 1256
now find the volume by multiplying the base and the height of the tank
Volume = 1256*35= 43960
The height of your scale model will be 37.8cm.
1.26 x 30
Answer:
$165, 5 months total, 4 more months
Step-by-step explanation:
First find 30% of 550 by converting 30% into a decimal to get 0.30. Then multiply 550 by 0.3 to get 165 as her savings each month. To find how ling she has to save, divide 825/165 to get 5 month. She must save for 5 month total or 4 more months to get the bike
Answer:
D.f(x) = −4x + 105
D.f(x) = −4x + 105
Step-by-step explanation:
Since the function in linear, we know it has a slope.
We know 2 points
(5,85) and (10,65) are 2 points on the line
m = (y2-y1)/(x2-x1)
= (65-85)/(10-5)
=-20/5
=-4
We know a point and the slope, we can use point slope form to write the equation
y-y1 =m(x-x1)
y-85 = -4(x-5)
Distribute
y-85 = -4x+20
Add 85 to each side
y-85+85 = -4x+20+85
y = -4x+105
Changing this to function form
f(x) =-4x+105
