Select all the expressions that can be used to find the price of a $400 telescope after a 32% markup. A)400 • 0.32 B) 400 • 3.2 C)400 • 1.32 D)400 + 400(0.32) E)400 • 400(1.32)
Answer:
(D) 400 + 400(0.32)
Step-by-step explanation:
We need to find the price of a $400 telescope after a 32% markup.
32% markup means increase in the cost of telescope by 32%. It can be calculated as follows :
[tex]P=400+32\% \ of\ 400\\\\=400+\dfrac{32}{100}\times 400\\\\=400+0.32(400)[/tex]
Hence, the correct expression is option (d).
Answer:
(D) 400 + 400(0.32)
Step-by-step explanation:
We need to find the price of a $400 telescope after a 32% markup.
32% markup means increase in the cost of telescope by 32%. It can be calculated as follows :

It took everly 55 minutes to run a 10-kilometer race last weekend. If you know that 1 kilometer equals 0.621 mile, how many mintues did it take everly to run 1 mile during the race?
Answer:
8.9 minutes
Step-by-step explanation:
Converting Everly Kilometer race to miles
1 km = 0.621 miles
10 km =
10 × 0.621 miles
= 6.21 miles
Hence,
6.21 miles = 55 minutes
1 mile = x minutes
Cross Multiply
6.21 × x = 55 × 1
x = 55 minutes/6.21
x = 8.8566827697 minutes
Approximately = 8.9 minutes

is a 4 sided polygon a rectangle
Answer: A rectangle is a 4-sided polygon where all four of its angles are right angles. Normally, the longer side is called the length and the shorter side is called the width. If all the sides are of equal length then it will be called a square. Area of rectangle = length × width.
Exlpination: A polygon is a closed figure with three or more straight sides. For example, a triangle is a polygon with three sides, a rectangle is a polygon with four sides, and a pentagon is a polygon with five sides.
Answer:
its a rectangle yea have a nice time

Write an equation in standard form of the line that passes through the given point
and has the given slope.
1. (2,-4), m= 2/3
2. (5, -3); m = 2
3. (6,0); m = 3/4
4. (-1, 2); m = 7
5. (-3,-5)m= 1/3
6. (4,0); m = -5
Answer:
y=2/3x-16/3
Step-by-step explanation:
ok ill show you how to do one question since the rest will take too long so what you do is
equation is y=mx+b right
so you have slope and these points (2,-4) and m=2/3
y=2/3x +b right
now all you do is sub in x and y which are ur given points
-4=2/3 (2) +b
now you solve for b
-4 = 4/3 + b
-4-4/3 = b
-12/3 - 4/3 = b
-16/3=b so therefore
y=2/3x-16/3
The price of a television was reduced $250 to $200. By the percentage was the price of the television reduced?
A. 20%
B. 25%
C. 80%
D. 50%
please help I'm not good at math!!
Answer:
B. 25%Step-by-step explanation:
The price decreased by 50, and that is 25% of 200.
Answer:
The answer is 20%
Step-by-step explanation:
I'm not amazing at percentages so this is what I did. Search up 20 percent of 250. Then it says 50. 250 minus 200 is 50, so the answer is 20%

is y=x/4 a proportional relationship
Answer:
yes
Step-by-step explanation:
The function f(x) = x/4 represents a proportional relationship.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. A straight line represents a proportional relationship. Mathematically -
y = mx + b
(y - b)/x = m [m is constant]
or
y = mx
m = y/x [m is constant]
Given is the following function -
y = x/4
We have -
f(x) = x/4
Now, we know a straight line represents a proportional relationship. The general form of equation representing the proportional relationship is -
y = mx
where - [m] is constant
y = x/4
y = (1/4)x
On comparing, we get -
m = 1/4
Hence, the function f(x) = x/4 represents a proportional relationship.
Therefore, the function f(x) = x/4 represents a proportional relationship.

2(x2 + 6) – 3 vy when x = 3 and y = 64.
Answer:
73
Step-by-step explanation:
you would do distributive property we know x= 3 so on the inside would be 32 now since we are doing distributive property you multiply 32x2 and 6x2
then you add them together and after you subtract 3 from 76 which = 73
PLEASE HELP! ILL GIVE YOU BRAINLIEST
Answer:
In the first picture is B
In the second is C
Step-by-step explanation:
Answer:
the first one is A. 2n + 2 and the second is C. 3(y + 2)
Step-by-step explanation:
So for the first one, 5n + 2 - 3n, is basically combining the factors with the variable n, so you subtract 3n from 5n, giving you 2n + 2, or A.
The second one is kinda reverse. You have to find the one that makes the most sense via Distributive Property. So what you do is separate 3 from the others and put y + 6 in parentheses, like this:
3(y + 6)
But this isn't the answer, as if you do the distributive property with this answer, you would get 3y + 18, and that's not what we want to get. So what we have to do is divide 6 by 3, giving us 2, thus giving us our answer of C.
Hope I helped! ^w^

Answer: Sam wrote 99 digits
Step-by-step explanation: Take the highest number minus the lowest number and that his how many numbers are between 12 and 111.
use the function below to find f(-2).
f(x)=3^x
hi
f(x) = 3^(x) so (f-2) = 3^(-2) = 1/ 3² = 1/9
Answer: 1/9
Step-by-step explanation:
slope intercept
y= 1/2x + 2
Don't know exactly what you're asking, but I think you're asking what the slope and what the y-intercept is.
1/2x is the slope
Positive 2 is the y-intercept
it y because of the equation mx +b and b is y
