Answer:
E. The new volume is 27 times the old volume.
Step-by-step explanation:
A rectangular prism has dimensions width w, height h and length l. It's volume is given by:
[tex]V = wdl[/tex]
Edges of a rectangular prism are increased by a scale factor of 3
Each dimensions is multiplied by 3, and the volume is:
[tex]V_m = 3w(3d)(3l) = 3*3*3wdl = 27wdl[/tex]
How will the volume change?
[tex]\frac{V_m}{V} = \frac{27wdl}{wdl} = 27[/tex]
Thus, the volume is multiplied by 27, that is, it is 27 times the old volume, and the correct answer is given by option E.

Which Which value of x makes this equation true? -3x+10=5x-8
value of x makes this equation true? -3x+10=5x-8
Answer:
9/4
Step-by-step explanation:
-3x+10=5x-8
or, -3x-5x = -8-10
or, -8x=-18
or, 8x=18 (i.e. - is cancelled)
or, x=18/8
i.e. x=9/4
Hence, the value of x is 9/4
Answer:
The value of x is 9/4
Step-by-step explanation:
-3x+ 10 = 5x - 8
Add 3x both side
-3x + 3x + 10 = 5x + 3x - 8
10 = 8x - 8
Now, Add 8 both side
10 + 8 = 8x - 8 + 8
18 = 8x
8x = 18
Now, Divide by 8 from both side
8x/8 = 18/8
x = 9/4
Thus, The value of x is 9/4
FOR VERIFICATION ONLY:-3x + 10 = 5x - 8
-3(9/4) + 10 = 5(9/4) - 8
-27/4 + 10 = 45/4 - 8
-27 + 4 × 10/4 = 45 - 8 × 4/4
-27 + 40/4 = 45 - 32/4
13/4 = 13/4
Hence, L.HS = R.H.S

Find the radius of a sphere with a surface area of $4\pi$ square feet.
Answer:
r = 1 feet
Step-by-step explanation:
Given that,
The surface area of the sphere, A = 4π feet²
We need to find the radius of the sphere.
The formula for the surface area of the sphere is given by :
[tex]A=4\pi r^2[/tex]
Where
r is the radius of the sphere
Put all the values,
[tex]4\pi = 4\pi \times r^2\\\\r=1[/tex]
So, the radius of the sphere is equal to 1 feet.

Step-by-step explanation: 1/2 chance it shows heads if you do it once so: 1/2 times 1/2
Answer:
[tex]$\frac{1}{4}[/tex]
Step-by-step explanation:
Each time you a flip a coin, there is a [tex]\frac{1}{2}[/tex] chance it lands on heads. Therefore, after flipping a coin twice, the probability that it lands on heads both times is:

Answer:
144 - 36pi
Step-by-step explanation:
1) Since the side lengths of the square are 12 units, the midpoints divide each side into two 6 unit lengths.
2) Those 6 unit lengths are radii of a quarter of a circle.
3) We can use the equation pi × r^2 to calculate the area of the four quarter circles.
4) pi × 6^2
5) 36pi
6) The area of the original square is 12 × 12, which is 144.
7) 144 - 36pi is your answer.

A pollster believes that 20% of the voters in a certain area favor a bond issue. If 49 voters are randomly sampled from the large number of voters in this area, approximate the probability that the sampled fraction of voters favoring the bond issue will not differ from the true fraction by more than 0.08. (Round your answer to four decimal places.)
Answer:
The probability that the sampled fraction of voters favoring the bond issue will not differ from the true fraction by more than 0.08 is 0.7698
Step-by-step explanation:
Given
n = 64
p = 0.20
X/n -p < 0.06
x-np <0.06n
x-np <0.06 * 64
x-np <3.84
Z score
= (x-np)/sqrt (np(1-p))
= -3.84/ sqrt (64*0.20*0.80)
= -1.20
P (x/n-p<0.06) = P(-1.2<z<1.20) = 1-2*0.1151 = 0.7698
What linear equation is represented by the table?
Please hurry!
Best answer gets Brainliest!!!!
A) Y= 2x
B) y= 4x
C) y= 4x -2
D) y= 2x - 2
Answer:
y = 4x - 2
Step-by-step explanation:
linear equation - y = mx + b
where m = slope and b = y intercept
The y intercept is the y value of the coordinate where x = 0
Looking at the table, we notice that when x = 0, y = -2
Which means that the y intercept ( b ) = -2
Slope = change in y over change in x
As y goes up 4 x goes up 1
Thus, slope ( m ) = 4
Now we plug in the identified slope and y intercept into " y = mx + b "
we get that the equation is y = 4x - 2
A researcher collected data on years spent in college and yearly income. He found that the longer someone is in college, the lower his/her income is. Which of the following is true based on this research? Select all that apply.
The line of best fit for this data would be increasing from left to right on the scatter plot.
The slope of the line of best fit for this data would be negative.
The -intercept for the line of best fit for this data would be zero.
The line of best fit for this data is horizontal because the variables are not related.
If you divided the data into two groups and found the average years of college and average yearly income from each of the two groups, you could find the estimated slope of the line of best fit by using the slope formula on those representative points.

If it takes 1/3 of a can of frosting to cover a small cake, how many cakes can you frost with 4 cans of frosting?
a. Solve the problem. Show your work.
b. Write the equation to represent the problem and the answer.
Answer:
Hello answer: 1 1/3
work: 1/3 × 4 = 1 1/3
equation: 1/3 × 4 = 1 1/3
Answer:
see explanation
Step-by-step explanation:
(a)
[tex]\frac{1}{3}[/tex] can → 1 cake
Number of thirds in 1 can = 3, then
Number of thirds in 4 cans = 3 × 4 = 12
Thus 12 cakes can be frosted with 4 cans
(b)
number of cakes = 4 ÷ [tex]\frac{1}{3}[/tex] = 4 × [tex]\frac{3}{1}[/tex] = 12

Hope it helps thx#CARRYONLEARNING!What is 6 1/3 yards in feet with explication
Answer:
6 1/3 yards = 19 feet
Step-by-step explanation:
1 yard = 3 feet
So we'll take the number of yards and multiply that by 3
6 yards x 3 feet/yard = 18 feet
for the 1/3 of a yard, you can either ask, "what's 1/3 of 3?" (= 1) or you can multiply 1/3 yard x 3 feet/yard = 1 foot.
Add up the parts, 18 + 1 = 19 feet

explanation process with problem = branliest and more points
Answer:
B
Step-by-step explanation:
So, this is a inequality.
The inequality is 2x+2 >= 10
Lets completly ignore the graphs for the moment, and just solve this inequawlity as we would like a normal equation.
So first, subtract 2 from both sides:
2x+2>=10
=
2x>=8
Now, divide by 2 to get x alone:
2x>=8
=
x>=4
So, we now know that x is greater than or equal to 4.
In a normal inequality, we would have to remember the following:
When it is greater than/less than or equal to the dot that marks the inequalities value is filled in.
When it is greater than/less than the dot that marks the inequalities value is open, kind of like a "o".
Also, recall that the dark black line that goes either left or right of the dot also varies:
If x is less than the dot that marks the inequalities value, then the dark black line with go left.
If x is greater than the dot that marks the inequalities value, then the dark black lne will go right.
So for our x>=4, since there is a equals sign, its a filled in dot.
So four our x>=4, since there is a greater than sign, the dakr black lines goes to the right.
Now, lets look at the graphs
There is only one that has the filled in dot on 4, and a black line that goes to the right. Thats B
So B is your answer!
Hope this helps! :)
Answer:
B
Step-by-step explanation:
In order to graph we must first isolate the variable.
We can do this by using inverse operations
2x + 2 ≥ 10
To get rid of the + 2 we subtract 2 because the expression is adding 2 and the inverse of addition is subtraction. But remember whatever we do to one side we have to do to the other so we subtract 2 from each side
2 - 2 cancels out
10 - 2 = 8
we now have 2x ≥ 8
Now we want to get rid of the 2 on "2x". 2x is the same as 2 times x and the inverse of multiplication is division, so we divide each side by 2
2x / 2 = x
8 / 2 = 4
we're left with x ≥ 4
To graph we place a point on "4" and fill in the point ( when the inequality sign is ≤ or ≥ we fill in the point )
When the inequality sign is facing the variable ( x ) the line will be going in the direction of right.
Hence, the answer is B
