A bookstore pays $28 for a copy of a
textbook. The bookstore sells the textbook
for $42. What is the percent markup on the
textbook?
F 14%
G 33%
H 50%
3 67%
Answer: H - 50%
Step-by-step explanation:
The percentage markup on the textbook on the given percentage will be 50%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost of a textbook = $28
Selling price = $42
% markup = (42 - 28)/28 x 100 = 50%
Hence "The percentage markup on the textbook on the given percentage will be 50%".

A drawing has a scale of 1:40 on the drawing a bedroom is a rectangle measuring 10 cm x 18 cm a kitchen has an actual area of 300,000 cm² which has the bigger actual area of the kitchen or the bedroom
Answer:
The kitchen has a bigger actual area than the bedroom
Step-by-step explanation:
Here, we want to know the compartment with the bigger area
Since the bedroom has a drawing measure of 1 to 40; compared to the actual measurement;
The real dimensions will be;
10 * 40 and 18 * 40
= 400 by 720
So, its area which is length * width will be;
400 cm * 720 cm = 288,000 cm^2
we can see that the kitchen with an area of 300,000 cm^2 is bigger than this area of the bedroom

What is m<XYZ? I don't know how to solve
Answer:
<XYZ = 83
Step-by-step explanation:
we can see that the line XY is tangent to point Y
we can also the see that <XYZ intersects the line that forms arc 166
when a tangent line intersect the line that forms an arc, the angle formed by the tangent will be equal to half of the arc
so in other words angle XYZ is 0.5 of Arc 166
so <XYZ = 83

2. What is the slope of the line that passes through the points M(-5,0) and N (6,8)?
Answer:
Hi how are you doing today Jasmine
The slope of the line that passes through the given points M(-5, 0) and N (6, 8) is [tex]\frac{8}{11}[/tex]
Given the following points:
Points on the x-axis = (-5, 6) Points on the y-axis = (0, 8)To calculate the slope of the line that passes through the given points M(-5, 0) and N (6, 8), we would use the following formula;
The slope of a line can be defined as the gradient of a line.
Hence, a slope is typically used to describe both the direction and steepness of an equation of a straight line.
Mathematically, the slope of a line is given by the following formula;
[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substituting the given points into the formula, we have;
[tex]Slope. \;m = \frac{8 - 0}{6 - [-5]}\\\\Slope. \;m = \frac{8}{11}\\\\Slope. \;m = \frac{8}{11}[/tex]

Reba used 12 centimeters of tape to wrap 3 presents.How much tape will Reba need in all if she has wrap 6 presents?
Answer:
24
Step-by-step explanation: We have to find out how much centimeters of tape we need to wrap one present, so you have to divide 12 by 3=4
so you need 4 centimeters of tape to wrap one present. Now we have to find out how much tape we need for 6 presents, so we do 4x6=24.
What is the sum of first k+1 even numbers
Answer:
[tex]Sum = (k+1)(k+2)[/tex]
Step-by-step explanation:
Given
k + 1 even numbers
Required
Their sum
This question will be solved using the sum of nth term of an AP
[tex]S_n = \frac{n}{2}(2a + (n - 1)d)[/tex]
Where
a = the first even number
[tex]a = 2[/tex]
n = number of terms
[tex]n =k +1[/tex]
d = difference between consecutive even numbers
[tex]d = 2[/tex]
So, the expression becomes:
[tex]Sum = \frac{k+1}{2}(2 * 2 + (k + 1 - 1) * 2)[/tex]
[tex]Sum = \frac{k+1}{2}(2 * 2 + (k) * 2)[/tex]
[tex]Sum = \frac{k+1}{2}(4 + 2k)[/tex]
[tex]Sum = \frac{(k+1)(4 + 2k)}{2}[/tex]
Factorize 4 + 2k
[tex]Sum = \frac{(k+1)*2*(2 + k)}{2}[/tex]
[tex]Sum = (k+1)*(2 + k)[/tex]
[tex]Sum = (k+1)*(k+2)[/tex]
[tex]Sum = (k+1)(k+2)[/tex]

On Thursday, 300 adults and children attended a show. The ratio of adults to children was 4 to 1. How many children attended the show?
Answer:
plz make it brainlisted
Step-by-step explanation:
Since the total is 300 and the ratio is 4:1,
Let us suppose the number of adults be 4x and children be x;
According to the question,
4x+x=300
or,5x=300
or,x=(300/5)
or,x=60
So, 60 students attended the show.
Answer:
75
Step-by-step explanation:
4:1 children meaning 1/4 of the population of 300 is 75

Answer:
B The equation is 4x = -48. Ben's point total is -12.
Step-by-step explanation:
Ben's total + Olive's total = -48
x + 3x = -48
4x = -48
x = -48 ÷ 4
Ben's total (x) = -12
Answer:
D
Step-by-step explanation:
If the Olive's is 3 times x, this can be written as 3x. Ben's score is just x. Combine those to get the equation 4x=-48. Divide to get x=-12

Mr. Lin writes the expressions
-20 - 8 and 8 - (-20) on the board.
He asks his class which result is greater. How can his class decide without finding
the value of each difference?
Answer:
Just see that the first expression has all negative, meaning the total will be a negative, but the second expression the subtraction sign and the negative sign are together, there's a rule when two negative sign's are together/next to each other, they turn into a addition sign, so it basically 8 + 20 for the second expression, so 8-(-20) has a higher result
Step-by-step explanation:
There's no work needed to be done :P
The first one will be all negative and the second one will be all positive
Which statement accurately describes the vector shown?
magnitude of StartRoot 11 EndRoot and direction angle equal to approximately 40°
magnitude of StartRoot 11 EndRoot and direction angle equal to approximately 50°
magnitude of StartRoot 61 EndRoot and direction angle equal to approximately 40°
magnitude of StartRoot 61 EndRoot and direction angle equal to approximately 50°
Answer:
The magnitude is definitely sqrt 61
Step-by-step explanation:
I am unsure how to mathematically solve for the direction angle but my educated guess would be C magnitude of sqrt 61 and direction angle equal to approximately 40° because the vector is below halfway of the 90 degree angle.
The magnitude and the direction of vector a are √61 and 40°. Then the correct option is C.
What is a vector?The quantity which has magnitude, direction and follows the law of vector addition is called a vector.
From the graph, we can see that the coordinate points of the vector that is given as (0, 0) and (5, 6)
Let a be the vector.
Then the magnitude of the vector will be
[tex]\rm \overrightarrow{a} =\sqrt{(6-0)^2 + (5-0)^2 } \\\\\overrightarrow{a} =\sqrt{6^2 + 5^2 }\\\\\overrightarrow{a} =\sqrt{36 + 25}\\\\\overrightarrow{a} =\sqrt{61}[/tex]
The direction will be
[tex]\rm \theta = tan^{-1} \dfrac{5}{6}\\\\\theta = tan^{-1} 0.833\\\\\theta = 39.80 \approx 40^o[/tex]
The magnitude and the direction of vector a are √61 and 40°. Then the correct option is C.

Sharon kicks a ball from the ground into the air with an upward velocity of 64 feet per second. The function h = -16t2 + 64t models the height h, in feet, of the ball at time t, in seconds. When will the ball reach the ground again?
Step-by-step explanation:
h = 64t - 16t².
When the ball reaches the ground, h = 0.
Therefore 64t - 16t² = 0, 16t(4 - t) = 0, t = 0 or t = 4.
Therefore the ball reaches the ground 'again' at t = 4.
