Answer:
6. 175/125=x/100
Cross products equal 125x=17500
Solve for x and you get 140%
7. 20% of 720 is 144. You need to find 120% so add the full 720 (100%) to the 144 and you get 864 (120%)
Step-by-step explanation:
The long way would be adding 10+10+10+...+10, 44 times. Or we can do it the fast way and multiply 44 by 10 since there are 44 tens.
44 * 10 = 440
Answer:
40.2
Step-by-step explanation:
law of cosines
x^2=40^2+28^2-2*28*40*cos(70)
put in calculator and square root the answer
40.222.... is approximately 40.2
Answer:
4021.2 cm³
Step-by-step explanation:
you start by getting the radius, the radius is half the diameter which in this case half of 16 is 8 so 8 is your radius and you already know the height which is 20, now that we have the radius and the height we can start
the formula for finding the volume of a cylinder is πr² · h
so are formula would be π8² · 20 which turns into π64 · 20 which then turns into 1280π or 4021.238...
which you then said we need to round the nearest tenth so 4021.238 to the nearest tenth is 4021.2 cm³
