The diameter of a cylindrical construction pipe is 4ft If the pipe is 17ft long, what is its volume? Use the value 3.14 for /pi, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.
Answer:
214 ft^3
Step-by-step explanation:
Here, we are asked to calculate the volume of the cylindrical construction pipe.
Mathematically, the volume V
V = pi * r^2 * h
r is radius = diameter/2 = 4/2 = 2 ft
h = 17ft
pi = 3.14
Putting these values, we have;
V = 3.14 * 2^2 * 17 = 213.52 which is 214 ft^3 to the nearest whole number

URGENT!!LAST QUESTION!!!! PLS JUST TAKE A LOOK! EASY BUT I AM DUMB!!!!!! WILL GIVE BRANLIEST!! The following two triangles are similar. Find the missing side length represented by x. A) 25.2 in B) 26.25 in C) 24 in
Answer:
[tex]x = 26.25[/tex] inches
Step-by-step explanation:
Since we know the triangles are similar, we can simply set up ratios to find the length of side length 'x'.
[tex]\frac{15.75}{x} = \frac{9}{15}[/tex]
Cross multiply:
[tex]236.25 = 9x[/tex]
Divide both sides by '9' to solve for 'x':
[tex]\frac{236.25}{9} = \frac{9x}{9}[/tex]
[tex]x = 26.25[/tex]
Therefore, side length 'x' equals 26.25 in.

solve for d
Answer:
d =±2sqrt(7) i
Step-by-step explanation:
d^2 = -28
Take the square root of each side
sqrt(d^2) = ±sqrt(-28)
d = ±sqrt(-28)
d = ±sqrt(-1)sqrt(28)
We know that sqrt(-1) = i
d =±i*sqrt(4)sqrt(7)
d =±i 2sqrt(7)
d =±2sqrt(7) i

Answer:
(a) Increased by %
(b) Increased by %
(c) Decreased by %
(d) Decreased by %
(e) Increased by %
(f) Decreased by %
GRADE ANSWER
Answer:
(a) Increased by 100%
(b) Increased by 50%
(c) Decreased by 33.33%
(d) Decreased by 50%
(e) Increased by 200%
(f) Decreased by 66.67%
Step-by-step explanation:
To calculate percentage change, we can use the following formula:
[tex]\text{Percentage Change =} \dfrac{\text{New value - Old Value}}{\text{Old Value}} \times 100[/tex]
Positive value of percentage change means increase and
Negative value of percentage change means decrease.
Solution a)
Old Value = 1
New Value = 2
[tex]\text{Percentage Change =} \dfrac{\text{2 - 1}}{\text{1}} \times 100\\\Rightarrow 100\%[/tex]
Increase of 100%
Solution b)
Old Value = 2
New Value = 3
[tex]\text{Percentage Change =} \dfrac{\text{3 - 2}}{\text{2}} \times 100\\\Rightarrow 50\%[/tex]
Increase of 50%.
Solution c)
Old Value = 3
New Value = 2
[tex]\text{Percentage Change =} \dfrac{\text{2 - 3}}{\text{3}} \times 100\\\Rightarrow -33.33\%[/tex]
Decrease of 33.33%.
Solution d)
Old Value = 2
New Value = 1
[tex]\text{Percentage Change =} \dfrac{\text{1 - 2}}{\text{2}} \times 100\\\Rightarrow -50\%[/tex]
Decrease of 50%.
Solution e)
Old Value = 1
New Value = 3
[tex]\text{Percentage Change =} \dfrac{\text{3 - 1}}{\text{1}} \times 100\\\Rightarrow 200\%[/tex]
Increase of 200%.
Solution f)
Old Value = 3
New Value = 1
[tex]\text{Percentage Change =} \dfrac{\text{1 - 3}}{\text{3}} \times 100\\\Rightarrow -66.67\%[/tex]
Decrease of 66.67%.
So, the answer is:
(a) Increased by 100%
(b) Increased by 50%
(c) Decreased by 33.33%
(d) Decreased by 50%
(e) Increased by 200%
(f) Decreased by 66.67%

Bernard is two years older than his sister Therese and four years younger than his sister
Josephine. The product of his sisters' ages is the age of his mother, 40.
A. If x is Bernard's age, write his two sisters' ages in terms of x.
Answer:
B. Write Bernard's mother's age in terms in terms of x and solve this quadratic equation.
Answer:
C. What is Bernard's age?
Answer:
Please show working out
Firstly Bernard = x
A) lets focus on Therese first. Bernard id two years older than her so for Therese’s equation in terms of x it would be x+2. Now for Josephine Bernard is 4 years younger than HER so it would be 4-x.
B) The mother is the PRODUCT of the sisters’ ages so (multiplication)
It would be like this: (x+2)(4-x)= 40 This is all in terms of x.
Solving for the equation (using distributive property) we get:
4x-x+8-2x=40
(Reorganize to group like terms, remember to go in order from the numeral numbers with variables, to variables only then numbers only): 4x-2x-x+8=40 (now combine like terms and simplify): x+8=40 this is his mom’s age in terms of x
C) HERE we can solve for x:
Isolating x to get the answer we move the 8 to the other side of the equation and it becomes a negative 8 so:
x=40-8
x=32
Therefore Bernard is 32 years old.

The quotient obtained by dividing the expression (3x³+10x²+10x+4) divided by (x+2) is 3x²+4x+2
What is Division?A division is a process of splitting a specific amount into equal parts.
We are asked to find the quotient obtained by dividing the expression
(3x³+10x²+10x+4) divided by (x+2)
We can also write this expression as i.e. we are asked to find the value of the expression:
3x³+10x²+10x+4/x+2
We can write the expression on the numerator as:
3x³+10x²+10x+4=(3x²+4x+2)(x+2)
Divide both sides by x+2
3x³+10x²+10x+4/x+2=3x²+4x+2(x+2)/x+2
3x³+10x²+10x+4/(x+2)=3x²+4x+2
Hence, the quotient obtained by dividing the expression (3x³+10x²+10x+4) divided by (x+2) is 3x²+4x+2

Amanda used 24 grams of paint to paint a wooden cube. When it dried, she cut the cube into 8 equal cubes. How many more grams of paint does Amanda need to paint the unpainted surfaces of the 8 cubes?
Answer:
Amanda needs 72 grams of paintStep-by-step explanation:
Notice that she already painted one face of each cube, that is, 8 faces in total, and she used 24 grams for that.
Now, there remain 3 faces per cube to be painted, which means there are 24 faces.
Then, we use the rule of three, if she used 24 grams of paint for 8 faces, how much grams of paint she would need to paint 24 faces?
[tex]24 \times \frac{24}{8}= 72 \ grams[/tex]
Therefore, Amanda needs 72 grams of paint for the unpainted surfaces.
When Cara drives to work, it takes her 30 minutes to drive 15 miles. On her days off, she likes to drive to her favorite donut shop. It takes Cara 6 minutes to drive to The Dreamy Donut Shop at the same rate. How many miles away is The Dreamy Donut Shop?
Answer:
3 miles
Step-by-step explanation:
First, we find the rate at which she drives, that is her speed.
Speed is given as:
speed = distance / time
When Cara drives to work, it takes her 30 minutes to drive 15 miles. Her speed is:
s = 15 / 30 = 0.5 miles per minute.
She drives at the same rate to The Dreamy Donut Shop and it takes her 6 minutes.
From the formula of speed, distance is given as:
distance = speed * time
Therefore, the distance of The Dreamy Donut Shop is:
distance = 0.5 * 6 = 3 miles
The Dreamy Donut Shop is 3 miles away.

Answer:
4096
Step-by-step explanation:
Lets start by applying a basic exponent rule. (a*b)^n is equal to a^n * b^n
Therefore,
((9(3/16)^-2)^3/2 = 9^3/2 * ((3/16)^-2)^3/2
Now lets focus on ((3/16)^-2)^3/2
(3/16)^-2 = 1/(3/16)^2 = (16^2/3^2)^3/2.
We can quickly eliminate the fractional exponent by plugging it into the numerator and the denominator and we get, 16^3/3^3 = 4096/27
So now we have, 9^3/2 * 4096/27
We can easily compute 9^3/2, which is (sqrt(9))^3, which is equal to 27.
Therefore, you have, 27*4096/27. The 27 cancels to give us a final answer of 4096
