Answer:
27.15
Step-by-step explanation:
Let us name the vertices as shown below
A(- 1, 6)
B(5, 1)
C(- 4, - 3)
We would calculate the distance between each vertex by applying the formula for calculating distance between 2 points. It is expressed as
The perimeter of the triangle is the sum of the length of each side. Thus,
Perimeter = 7.81 + 9.85 + 9.49
Perimeter = The perimeter of the triangle is the sum of the length of each side. Thus,
Perimeter = 27.15
Answer:
2
Step-by-step explanation:
The input would be 7
You do the number machine ‘in reverse’ to figure it out from output to input.
17 - 3 = 14
14 / 2 = 7
Surface area=2A + BH
where A is the area of the base, B the perimeter of the base and H the height.
S.A=2*4.5*6 +2(4.5+6)*12
S.A=54+252
S.A= 306 sq. inches
<u>For W, </u><u>W = 28B.</u>
Given that one concrete block is 28 pounds, and that B is the number of blocks, we can multiply both values to get the amount of pounds, or weight, of the quantity of B blocks. So <em>W = 28B.</em>
<u>For B, </u><u>B = W ÷ 28</u>
Now that we know the equation for the weight, W = 28B, we can divide both sides by 28 to isolate the variable, B. The equation now becomes <em>B = W ÷ 28. </em>
