Answer: 34 in^3
Step-by-step explanation:
Surface area of triangle = 1/2 x 3.4 x 2.5 = 4.25
To find the volume of the prism, multiply the surface area of the triangle by length.
So 4.25 x 8 = 34 in^3
Answer:
X= 35/6
Y= -14/3
Step-by-step explanation:
To solve for X:
Replace Y by 0:
12y=70
X=35/6
To solve for Y:
Replace X by 0:
-15y=70
Y= -14/3
Answer:
25 mL
Step-by-step explanation:
You subtract the amount of water in the cylinder with the rock, from the amount of water in the cylinder without the rock. The equation is 75mL - 50 mL
To find the amount needed to build the fence you would first need to find the perimeter of the rectangle. Which the formula is P=2(l+w).
Then you plug in your numbers into the formula and you’ll get P=2(90.66+45.5)
Then you can do the math or type it into a calculator and you’ll get 272.32................Then just leave the numbers after the decimal out and 272 should be your estimated answer
