Answer:

Step-by-step explanation:
we know that
The area of the right triangle ABC is equal to

the formula to calculate the distance between two points is equal to

we have
A(10, 7), B(5, 9), and C(3, 4)
step 1
Find the distance AB
A(10, 7), B(5, 9)
substitute in the formula



step 2
Find the distance BC
B(5, 9),C(3, 4)
substitute in the formula



step 3
Find the area
substitute the values


Answer:
The boxes of kazoos Mr. Jackson needs to order (26 + 24 + 30) ÷ 8.
We have given that,
There are 26-second graders, 24 third graders, and 30 fourth graders.
What is the expression?
An expression, in math, is a sentence with a minimum of two numbers and at least one math operation contain in it.
The amount of kazoos needed is 1 for every student
26 + 24 + 30
Since 8 come in each box, you divide by 8
To get your answer of (26 + 24 + 30) ÷ 8.
Divide 8 by 9
8 / 9 = 0.888
0.88 is greater than 0.60 so it is not between 0.45 - 0.60
