Answer:
12.75ft²
Step-by-step explanation:
Step 1: Determine the formula for the area of a trapezoid
The formula for the area of a trapezoid is A=1/2(b1+b2)*h where b1 and b2 are the bases of the trapezoid and h is the height of the trapezoid.
Step 2: List given information
b1=8ft
b2=9ft
h=1.5ft
Step 3: Plug given variables into the formula
A=1/2(b1+b2)*h
A=1/2(8+9)*1.5
A=1/2(17)*1.5
A=8.5*1.5
A=12.75
So the area of the seat is 12.75ft²

a+(-7)+3=0
a=7-3
a= 4
Answer:
4
Step-by-step explanation:
There are two ways of going about this problem. One could simply substitute every given answer and simplify to see if it makes a true statement. Conversely, one could solve the given equation with inverse operations. In this case, it is easier to solve with inverse operations.
Undo parenthesis,
a + (-7) + 3 = 0
a - 7 + 3 = 0
Simplify,
a - 7 + 3 = 0
a - 4 = 0
Inverse operations,
a - 4 = 0

a = 4
. A solid metal cylinder of radius 5 cm and height 12 cm is melted down and recast into a
cone of base radius 10 cm.
Calculate the height of the cone.
Answers
Answer:
H = 9 cm
Step-by-step explanation:
The volume of the cylinder equal the volume
[tex]\pi\: \: {r}^{2} \times hcy = \frac{1}{3} \pi {r}^{2} \times hco \\ hco = 9 \: cm[/tex]
The height of the cone is 9 cm.
The volume of the cylinder = The volume of the Cone
This is because the exact metal cylinder was recast into a cone.
Volume of a cylinder:volume = πr²h
r = 5 cm
h = 12 cm
volume = π × 5² × 12
volume = π × 25 × 12
volume = 300π
Volume of a cone:volume = 1 / 3 πr²h
r = 10 cm
h = ?
300π = 1 / 3 × π × 10² × h
300π = 100πh / 3
900π = 100πh
h = 900π / 100π
h = 9 cm

A clothing store donated a percent of every sale to charity . The total sales were $6,380 so the store donated $319. What percent of $6,380 was donated to charity ?
Answers
5% Because when you minus them it will be 6061 and 6061/6380 converted ad a fraction will be 95% so that means that 5% is subtracted
319 / 6,380 = 0.05
Multiply your quotient by 100.
0.05 * 100
But even without the second step, it’s easy to see that your solution is 5.
The store donated 5% of their sales.
