Answer:
3x, 2x + 5, and x - 3
Step-by-step explanation:
Since the given figure is a 3-dimensional shape, we know that there must be three zeroes.
Our equation is:
6x³ - 3x² - 45x
First, we can factor out an x:
x (6x² - 3x - 45)
From here, we can see that by factoring out a 3:
3x (2x² - x - 15)
Now, after completing the square and factoring:
3x (2x + 5) (x - 3)
These are our three expressions.

-X^2 + 5x + 24
The x-intercepts occur where x = ... and x =...
Please help! Also please don’t comment just for points it’s not funny and I need this so I can raise my score back up.
Answer:
x = 8 and x = -3.
Step-by-step explanation:
-x^2 + 5x + 24 = 0 at the x intercepts.
Divide thru by -1:
x^2 - 5x - 24 = 0
(x - 8)(x + 3) = 0
x - 8 = 0 , x + 3 = 0
x = 8 and x = -3.
A company is going to make a water tank in the shape of a cylinder. As shown below, the tank will have a height of 4ft and a radius of 6ft. The tank will be made from metal (including its top and bottom). Suppose the total cost of the metal will be $14,318.40. How much will the metal cost per square foot? Use 3.14 for pi, and do not round your answer.
First find surface area.
I will skip the exact explanation and just go to it because well its the same concept as the prism.
π*6^2*2+6*2π*4
=72π+48π
=120π
Now we need to take 3.14 for pi getting about
120*3.14=376.8 square foot.
Now the total is 14318.4 dollars, so what's left is simple division.
14318.4/376.8=38
The metal cost 38 dollars per square feet :P

The number of people who sleep 8-8.9 hr per night is about how many times the number who sleep 6-6.9 hr a night
Answer:
3.75 times
Step-by-step explanation:
From the histogram plot of the data :
The number of people who sleep 8 - 8.9 hour per night is about 375
The number of people who sleep 6 - 6.9 hour per night is about 100
Therefore, to compare how many times the number of people who sleep 6 - 6.9 hrs and 8 - 8.9 hrs :
8 - 8.9hrs = 6 - 6.9 hrs * x
375 = 100x
x = 375 / 100
x = 3.75
Hence, the number of people who sleep 8 - 8. 9 is 3.75 times the number of people who sleep 6 - 6.9
3.5(2.25 + x) = 14
x=
Answer:
x = 1.75
Step-by-step explanation:
Given
3.5(2.25 + x) = 14 ( divide both sides by 3.5 )
2.25 + x = 4 ( subtract 2.25 from both sides )
x = 1.75

Step-by-step explanation:
Solve the following equation for x.
3x - 9 = -42
Answer:
x = -11
Step-by-step explanation:
Add 9 to both sides of the equation
3 − 9 = −42
3 − 9 + 9 = −42 + 9
Simplify
Add the numbers
3 = −33
Divide both sides of the equation by the same term
3 = −33
3/3 = −33/3
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
= −11
In ΔOPQ, q = 83 inches, p = 80 inches and ∠P=70°. Find all possible values of ∠Q, to the nearest degree
Answer:
77.12°
Step-by-step explanation:
Given that:
In triangle OPQ
∠P=70°
line q = 83 inches
line p = 80 inches
To find ∠Q; we use the since rule:
[tex]\dfrac{Sin \ Q}{q} = \dfrac{Sin \ P}{p}[/tex]
[tex]\dfrac{Sin \ Q}{83} = \dfrac{Sin \ 70}{80}[/tex]
[tex]Sin \ Q= \dfrac{Sin \ 70 \times 83}{80}[/tex]
[tex]\text{Sin \ Q= 0.9749}[/tex]
[tex]Q=Sin ^{-1}( 0.9749)[/tex]
[tex]\mathbf{Q = 77.12^0}[/tex]

1 cm
7
cm
4
2 cm
cubes
Answer:
14
Step-by-step explanation:
1 x 2 x 1 3/4 (or 1.75) = 3.50
Now, divide 3.50 by 1/4 (or 0.25) to get 14
14 1/4 centimeter cubes will fill the prism
You are in a hurry and I don't think that you really need the explanation so its 224 cubes

Rayna and Maya are playing the integer card game. The cards in Rayna's hand are shown below: What is the total score of Rayna's hand? Support your answer by showing your work.
Answer:
The total score of Rayna's hand is described below in details.
Step-by-step explanation:
Start at 0. Combining a positive integer is a simplistic addition. Add 3 to get 3.
Combining a negative integer is like deducting : 3 + (-5) = 3 - 5 = -2.
Add 9, using 9 steps ahead, on the number line, to get 7.
Add -6, by deducting 6, to get 1.
Rayna's total composition is 1.
As for part 2, Rayna obtaining two more cards, which doesn't change his final record ...
Unless he got 2 zeroes, or he got pair cards with different symbols but similar magnitudes, such as 1 and -1.
The sign of a number is whether it is negative or positive. The magnitude (total value) of a number is how far that amount is from zero. The magnitude of a product is never negative.
The 2 cards do not change Rayna's point total, because their influences eliminate each other out. For instance, a 1 would move him one move ahead, on the number line, and a -1 would produce him one move behind, on the number line.

We need to study the structure well
We can find the magnitude of the big rectangle. We will need to find the total length and total breadth of the big rectangle
Then we remove the area of the four squared cut out from the big rectangle.
Total length of the rectangle is 5+1+1=7m
Then the length of the breath of the rectangle is 2+1+1=4m
So area of rectangle is given as length × breadth
Area= l×b
Area=7×4=28m²
Area of the big rectangle is 28m²
Then the squared is made of dimension 1m by 1m
Area of a square is s²
Then, a=1m
Area of the square= 1²=1m²
There are four squared side
Then, the total area of the four squared is 4×1=4m²
Then the required area is
Area=Total area - area of four squared side
Area=28m²-4m²
Area =24m²
Area of the figure is 24m²
The correct option is A.

what percent of 82 is 9.75. Round your answer to the nearest tenth
Hi there!
8 would be the nearest ten of 7.995..
1.Multiply 82 with 0.01:
[tex]82[/tex]·[tex]0.01=0.82[/tex]
2.Multiply the terms:
[tex]0.82[/tex]·[tex]9.75=7.995[/tex]
3.Round the term:
[tex]7.995=8[/tex]
Therefore, 82% of 9.75 in nearest tenth is 8.

Convert the following equation to slope-intercept form:
5x - 15y = 105
Answer:
D
Step-by-step explanation:
You need to solve the equation so that it looks like y = mb + b
So -15y = -5x + 105, then divide both sides by -15 so y = -5/-15 x + 105/-15
y = [tex]\frac{1}{3}[/tex] x - 7
