First, you have to know the formula of finding the area of a triangle. That is bh1/2. You multiple the base and height together and multiply it by 1/2 or divide by 2. You put in the info they gave you in the formula, after that you get 105/8. That is obviously not one of the choices and it is an improper fraction. The way to make it into a whole fraction is to do 105 divided by 8. Then, you get 13, which is the second answer. Finally, the area of the triangle is 13 1/8 squared mm.
Answer:
9/8
Step-by-step explanation:
to divide by a fraction multiply by the reciprocal of the fraction
3/4×3/2
multiply the fractions
3/4×3/2
3×3=9
4×2=8
9/8 is your answer
Ana, Betty and Carol in the ratio of 2:3:5 respectively
mom cut the $600 in (2+3+5) 10 parts
and gave 3 parts to betty
so B got 600 : 10 x 3 = $180
Hey there! :)
Answer:
Choice D. V = 2184 in³.
Step-by-step explanation:
Recall that to find the volume of a rectangular prism, the following formula is used:
V = l × w × h
Plug in the given dimensions into the formula to solve for the volume:
V = 14 × 13 × 12
Multiply:
V = 2184 in³. The correct answer is D.
If you're finding diameter or radius based on circumference, use the formula C = πd. You would divide the circumference by pi to get the diameter, then divide the diameter by 2 to get the radius.
If you're finding diameter or radius based on area, use the formula A = πr^2. You would divide the area by pi, then find the square root of that value which is the radius. Just multiply the radius by 2 to find diameter.
