Answer:
Volume= 216 cubic yards
Surface area: 276 square yards
Step-by-step explanation:
Find volume of rectangular prism:
V= lxwxh
V= 3x18x4
= 216 cubic yards
Find surface area:
SA= 2 x (front/back area) + 2 x (right/left area) and 2 x ( bottom/top area)
Front and Back Area:
A= l x w
A = 18 x 3
= 54 square yards
Right/ left Area:
4 x 3
= 12 square yards
Top/ Bottom Area:
18 x 4
= 72 square yards
54^2+12^2+72^2
= 108+24+144
=276 square yards
‘Translated two units upwards’. This means that the y-value of every point wil raise with 2 units. That’s why answer D is the right one.
Answer:
5/6
Step-by-step explanation:
Find the lowest common denominator between the 10 and 12.
10 and 12 have the lowest common denominator of 2
10/2=5
12/2=6
So 5/6 is the lowest term of 10/12
Answer: There were 7 children
Step-by-step explanation:
Let's use <em>x </em>to represent the children and <em>y </em>to represent the adults.
We know they combine to make a group of 25 people so x+y=25
We also know that they paid $201 and that there is $3 per child and $10 for adults so 3x+10y=201
I will solve by substitution.
Solve for y in the first equation
Sub in our value for y into the other equation and solve for x
Step 1) Simplify
Step 2) Subtract 250 from both sides
Step 3) Divide both sides by -7
