9. A triangle has an area of 36 yd2 and a base of 3 yd, what is the height of the triangle?
Answers
Answer:
24yards
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf 24 \ yards}}[/tex]
Step-by-step explanation:
The formula for a triangle's area is:
[tex]a= \frac{1}{2} bh[/tex]
We know the area is 36 square yards and the base is 3 yards.
[tex]a= 36 \ yd^2 \\b= 3 \ yd[/tex]
Substitute the values into the formula.
[tex]36 \ yd^2 = \frac{1}{2} (3 \ yd )h[/tex]
Divide by 1/2 or multiply both sides by 2.
[tex]2 * 36 \ yd^2 = \frac{1}{2} (3 \ yd )h *2[/tex]
[tex]72 \ yd^2= (3 \ yd)h[/tex]
We are trying to solve for the height, so we must isolate that variable. h is being multiplied by 3. The inverse of multiplication is division, so we must divide both sides by 3 yd.
[tex]\frac {72 \ yd^2}{3 \ yd}= \frac{(3 yd) h}{3 \ yd}[/tex]
[tex]24 \ yd =h[/tex]
The height of the triangle is 24 yards.

The volume of a cube is 8 in^3 What is the length of one side?
2.7in3
2 in3
2.7 in
2 in
Answers
Answer:
2 in
Step-by-step explanation:
Use the cube volume formula, V = s³, where s is the side length
Plug in 8 as V and solve for s:
V = s³
8 = s³
Take the cube root of both sides:
2 = s
So, the length of one side is 2 inches.
The length of one side of cube will be 2 in i.e. option D.
What is volume ?Volume is the amount of space that something contains or fills.
Volume of the cube = side³ = a³
We have,
Volume of the cube = 8 in³
And,
Side of cube = a
So,
Volume of the cube = side³ = a³
i.e.
8 = a³
⇒ a³ = 8
a = ∛8
On solving we get,
a = 2
i.e.
Side of cube = 2 in
Hence, we can say that the length of one side of cube will be 2 in i.e. option D.

Previous 20 Item 20 The width of a rectangular room is 60% of its length. The length of the room is 10 feet. What is the area of the room
Answers
Explanation: w=10*0.6=6 ft.
A=lw
A=10*6=60 square feet.
Answer: 60 feet²
Step-by-step explanation:
The width of the rectangular room is 60% of the length which is 10 feet.
The width is therefore:
= 60% * 10
= 6 feet
The area of a rectangle is calculated by the formula:
= Length * Width
Area there is:
= 10 * 6
= 60 feet²

A city has 17391 registered Democrats and 20553 registered
Republicans. An organization wishes to survey equal proportions of
each group.
The council decides to survey 13 Republicans
How many Democrats should they survey? Democrats
Answers
Answer: The council should survey 11 Democrats.
Step-by-step explanation:
A proportional relationship is written as:
y = k*x
Where k is the constant of proportionality. y is the number of surveyed members, and x is the total number of registered members.
If we use the same proportion for each case, then we will use the same value of k.
We know that there are 20553 registered Republicans, and the council decides to survey 13 of them, then we will have the relation:
13 = k*20553
Now we can solve this for k:
13/20553 = k
Then the proportional relationship will be:
y = (13/20553)*x
The number of democrats they should survey can be found if we replace x by the number of registered Democrats, then we use x = 17391
this leads to:
y = (13/20553)*17391 = 11
The company should survey 11 Democrats.

The cost, C. of producing coolers, x, is modeled by the equation C = 0.005x2 - 0.3x + 17. How many coolers are
produced when the cost is $19. Round your answers to the nearest whole number
All work must be clearly shown, step by step, to receive full credit. Separate your work. Each new statement or
equation, must be on a new line.
Answers
Answer:
66 coolers
Step-by-step explanation:
C = 0.005x² - 0.3x + 17
When C = $19
19 = 0.005x² - 0.3x + 17
19 - 17 = 0.005x² - 0.3x
2 = 0.005x² - 0.3x
0.005x² - 0.3x - 2 = 0
x = -b ± √b² - 4ac / 2a
= -(-0.3) ± √-0.3² - 4*0.005*-2 / 2*0.005
= 0.3 ± √ 0.09 - (-0.04) / 0.01
= 0.3 ± √ 0.09 + 0.04 / 0.01
= 0.3 ± √ 0.13 / 0.01
= 0.3/0.01 ± √0.13/0.01
= 30 ± 0.36/0.01
x = 30 ± 36
x = 30 + 36 or 30 - 36
x = 66 or -6
Number of coolers can not be negative
Therefore, number of coolers produced when the cost is $19
is 66 coolers
