Answer:
A. 2
Step-by-step explanation:
The computation is shown below:
As we know that
The Volume of a right circular cylinder is
[tex]V = \pi r^h\\\\[/tex]
Here r is the radius
And h is the height
Now it is mentioned that the height of the right circular cylinder P is double to the height of the right circular cylinder Q
Now let us assume h be the height of cylinder p
And, H be the height of cylinder Q
So the equation is
h = 2H ........(1)
Also
The radius of both the cylinders would be the similar length
So
we assume the r be the radius of both cylinders
Now
The Volume of cylinder Q = [tex]V_Q = \pi r^2H[/tex]
And for P it is [tex]V_p = \pi r^2 h[/tex]
Now substitute equation 1
[tex]V_p = \pi r^2(2H)\\\\V_p= 2 \pi r^2hH\\\\V_p = 2(\pi r^2H)\\\\V_p = 2(V_Q)[/tex]
Hence, the correct option is A.
Find X (30,60,90) need help asap asap
Answer:
The correct answer will be X = 4
Step-by-step explanation:
Using Pythagoras
AB^2 + BC^2 = AC^2
2^2 + (2√3)^2 = AC^2
4 + (4*3) = AC^2
4+12 = AC ^ 2
AC ^2 = 16
AC = √16 = 4
What percent of 4 is 7?
7 is the number 175 percent of 4.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Let n be the required percentage.
So,
n percent of 4 is 7.
That means,
4 x n/100 = 7
n = 700/4
n = 175%
Therefore, 175% is the required percentage.

Which expression is equivalent to 8-(6r+2)?
-6r+6
2r+2
6r+10
-6r+10
Answer:
-6r+6
Step-by-step explanation:
Let us expand the expression:
8-(6r+2)=
8-6r-2=
6-6r
OR
-6r+6
I hope this helps! :)
Answer:
6r+6
Step-by-step explanation:
we dont know the variable's number value yet so you can't solve anything with the 6r. We use distribbutive property and solve 8-2 since the 8 is just subtracting everything in the parenthesis. 8-2=6 and you can't do anything with the 6r so the expression would end up as 6r+6.

Anne is choosing a contractor. She has narrowed down her selection to two
companies and will base her decision on the likelihood that the job is done on
time and on budget. She uses online reviews to estimate the probabilities.
Which contractor should Anne choose to maximize the probability that the job will be done on time and on budget? Assume all events are independent.
Answer: A. Contractor A. The probability that both conditions are met is 0.93
Step-by-step explanation:
Probability of two independent events happening can be found by multiplying them.
Probability of A doing the job on time and on budget:
= Probability that job is done on time * Probability it is done on budget
= 0.97 * 0.96
= 0.93
Probability of B doing the job on time and on budget:
= 0.93 * 0.98
= 0.91
Contractor A has the better probability at 0.93 so should be chosen.

Answer: mannn i dunno either i’m tryna figure out the same thing
Step-by-step explanation:
The value of k in the expression is equal to 2.
What is cubic polynomial?The expression is in the form of Cubic polynomial. A cubic polynomial is the one which can be written in the form y = ax³ + bx² + cx + d where a, b, c and d are coefficients and x, and y are independent and dependent variables respectively.
here, we have,
given that,
The cubic polynomial,
f(x) = 2x^4 + 6x^3 – 10x^2 + kx – 10 ,has a factor equal to (x-1).
If it is the factor, then x = 1 is the solution of cubic polynomial
and at x = 1 the value of f(x) = 0.
2x^4 + 6x^3 – 10x^2 + kx – 10 = 0
2(1)^4 + 6(1)^3 – 10(1)^2 + k(1) – 10 = 0
2 + 6 -10 + k = 0
k - 2 = 0
=> k = 2, which is the required value.
Hence, The value of k in the expression is equal to 2.

The mean (average) of 4 numbers is 88.
What is the fourth number if three of the numbers are 80, 95, and 85?
A. 92
B. 54
C. 75
D. 99
E. None of these
Step-by-step explanation:
Add up the four test scores (80, 95, 85, x) then divide by 4 and set that result equal to 88. The equation you get is (80+95+85+x)/4 = 88. Now solve for x.
(80+95+85+x)/4 = 88
(260+x)/4 = 88
4*(260+x)/4 = 4*88
260+x = 352
x+260 = 352
x+260-260 = 352-260
x = 92
The fourth missing number is 92
b) y= 5/x What happens to the value of y if the value of x triples? Select your answer. A. x2 B. x3 C. /2 D. /3
Answer:
D.)
Step-by-step explanation:
y = 5/x
so when the value of x triples, the new X becomes;
X = 3x
So,
Y = 5/ X
=> Y = 5/3x
=> Y = 1/3 . 5/x
=> Y = 1/3 . y
so the new value of y ( Y ) is 1/3 times original y.
Hence, D. is the answer

Answer:
The table will be:
x 0 1 2 -1 3 1/3
y=3x-1 -1 2 5 -4 8 0
Step-by-step explanation:
We are given the equation: y = 3x-1 and we need to fill the table.
We have to put value of x and find value of y
When x = 0
y= 3(0)-1 = 0-1 = -1
So, x=0, y=-1
When x = 1
y=3(1)-1=3-1 = 2
So, x=1, y=2
When x = 2
y=3(2)-1=6-1 = 5
So, x=2, y=5
Now, we are given y=-4 and we need to find x
y=3x-1
-4=3x-1
-4+1=3x
3x=-3
x=-3/3 = -1
So, y = -4, x = -1
Now, we are given y=8 and we need to find x
y=3x-1
8=3x-1
8+1=3x
3x=9
x=9/3 = 3
So, y = 8, x = 3
Now, we are given y=0 and we need to find x
y=3x-1
0=3x-1
0+1=3x
3x=1
x=1/3
So, y = 0, x = 1/3
The table will be:
x 0 1 2 -1 3 1/3
y=3x-1 -1 2 5 -4 8 0

28/23 rounded to nearest tenth?
Answer:
1.22
Step-by-step explanation:
28/23=1.21739130435.
rounded to the nearest tenth would be:
1.22
The given number 28/23 is rounded to the nearest mile as 1.2.
The given fraction is 28/23.
The decimal number for the given fraction is 1.217
Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.
Here, in 1.217 digit in the hundredths place is 1, which is less than 5.
So, the digit in the tens place remain same and digits after tens place becomes zero.
That is, 1.2
Therefore, the given number 28/23 is rounded to the nearest mile as 1.2.
