Answer:
No
Step-by-step explanation:
4x+5 is not equivalent to 4(x+5) because when you solve for 4(x+5) using distributive property it equals 4x+20 which is not the same as 4x+5.
Answer:
Step-by-step explanation:
No, 4x+5 does not equal 4(x+5), because the operations are different for each expression.
4x+5 is an addition expression and 4(x+5) operation is multiplication.
You must using the distributive property to find the product: 4(x+5) = 4(x) + 4(5) = 4x +20
Therefore, 4x+5 is not equivalent to 4(x+5).
4x+5 is not equivalent to 4x+20.
The height of a cylinder is twice the radius of its base
Answer:
2πr³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ← r is the radius and h the height
Here h = 2r, hence
V = πr² × 2r = 2πr³

What is m∠1? Help me, please
Answer:
∠1 = 72°
Step-by-step explanation:
exterior ∠ = the sum of two opposite(remote) interior ∠s
∠1 = 37° + 35°
=> ∠1 = 72°
Answer:
72 degrees.
Step-by-step explanation:
Angle 1 is one of the triangle's exterior angles. The exterior angle theorem states that the measure of a triangle's exterior angle is equal to the sum of the opposite interior angles. Therefore, m<1 is equal to the sum of 35 and 37:
35+37=72
m<1 = 72 degrees

What is the measure of z?
Angles are not necessarily drown to scale.
B
156°
А
0
0
Answer:
The missing angle is 24 degrees
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
x+156 = 180
Subtract 156 from each side
x+156-156 = 180- 156
x = 24
The missing angle is 24 degrees

Answer:
92 is your answer
Step-by-step explanation:
we have
3x/4-1=x/2+7 side of square are equal
3x/4-x/2=7+1
(3x-2x)/4=8
x=8×4=32
length =3×32/4 -1=24-1=23
now
perimeter=4×length=4×23=92 units
Answer: The perimeter of the square is 92 units.
Step-by-step explanation:
All four sides of a square are equal. Set the given values 3/4x - 1 and 1/2x + 7 equal to one another. It should like this: 3/4x - 1 = 1/2x+7. The next step is solving for x. We get x = 32 as our answer. See the image of the work below if you are confused. :) Next, plug in this answer to the original equations: 3/4x-1 and 1/2x+7.
3/4(32) - 1 = 23
1/2(32) + 7 = 23
After basic substitution, we will conclude that each side of the square is 23 units long. To find perimeter use the equation 4s (let s represent sides). 4(23) = 92 units. Hope this was helpful!

At the craft store, Janice bought a bag of green and yellow marbles. She received 14 green marbles and 11 yellow marbles. What percentage of the marbles were green?
Answer: 56%
Step-by-step explanation:
Since Janice bought a bag of green and yellow marbles and she received 14 green marbles and 11 yellow marbles, the total number of marbles will be:
= 14 + 11 = 25 marbles
Number of Yellow marbles = 11
Number of Green marbles = 14
Total number of marbles = 25
The percentage of the marbles that were green will be:
= Number of Green marbles / Total marbles × 100
= 14/25 × 100
= 14 × 4
= 56%

Answer:
x = 112
Step-by-step explanation:
1/8x + 2 = 16
Subtract 2 from both sides
1/8x = 14
Multiply both sides by 8
x = 112
At a local restaurant, the amount of time that customers have to wait for their food is
normally distributed with a mean of 32 minutes and a standard deviation of 3
minutes. Using the empirical rule, determine the interval of minutes that the middle
99.7% of customers have to wait.
Answer:
.........................
Step-by-step explanation:
.................................................
Answer:
99.7% of customers have to wait between 8 minutes to 30 minutes for their food.
Step-by-step explanation:
We are given the following in the question:
Mean, μ = 18 minutes
Standard Deviation, σ = 3 minutes
We are given that the distribution of amount of time is a bell shaped distribution that is a normal distribution.
Empirical Formula:
Almost all the data lies within three standard deviation from the mean for a normally distributed data.
About 68% of data lies within one standard deviation from the mean.
About 95% of data lies within two standard deviations of the mean.
About 99.7% of data lies within three standard deviation of the mean.
Thus, 99.7% of the customers have to wait:
`
Thus, 99.7% of customers have to wait between 8 minutes to 30 minutes for their food.

The China Company offers a trade-discount rate that is 4 times the complement of the trade-discount rate. If the list price is $58.75, what is the trade discount? What is the net price?
Answer: See explanation
Step-by-step explanation:
Since the complement is the difference between 100% and discount rate. Since the China Company offers a trade-discount rate that is 4 times the complement of the trade-discount rate. Therefore, the discount rate will be 80% and the complement 20%.
Therefore, the trade discount will be:
= List price × Trade discount rate
= $58.75 × 80%
= $58.75 × 0.8
= $47
Net price = List price - Trade discount
= $58.75 - $47
= $11.75

What is the gradient of the line that passes through the points (0,0) and (3,3)?
Answer:
1
Step-by-step explanation:
the gradient is a value that indicates how much the x value increases as the y value increases. It can be written as
rise/run
or
change in y value/change in x value
or
(y1-y2)/(x1-x2), where we know two coordinates (x1,y1) and (x2,y2).
We have two coordinates (0,0) and (3,3)
Therefore,
x1 = 0, y1 = 0
x2 = 3, y2 = 3
If we plug these values into the formula, it is [tex]\frac{3-0}{3-0} = \frac{3}{3} = 1[/tex]
Here are three intersecting lines. Write an equation that represents a relationship between these angles. Describe, in words, the process you would use to find .
Answer:
[tex]w = 52[/tex]
Step-by-step explanation:
Given
See attachment for intersecting lines
Required
Find w
Using the horizontal line as a point of reference, the blank angle between w and 76 equals w.
This is so because it corresponds to angle w, at the bottom of the horizontal line.
So, to find w, we make use of:
[tex]w + w + 76 = 180[/tex] --- angle on a straight line
Collect like terms
[tex]w + w = -76 + 180[/tex]
[tex]2w = 104[/tex]
Solve for w
[tex]w = \frac{104}{2}[/tex]
[tex]w = 52[/tex]
