2. find the volume of a triangle with side lengths 3, 4, and 5.

v=20

Step-by-step explanation:

To calculate the volume of a pyramid we will use the formula where l and w are the length and width of the base, and h is the height.

So:

l=3

w=4

h=5

applying the values in the formula

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
