An internet company randomly selected 50 of its
customers and asked them how many hours per
week they use the internet. Of those surveyed, 28
use the internet more than 15 hours per week.
Based on the data, if the company has 800
subscribers how many watch more than 10 hours
per week?
Answer:
448 subscribers
Step-by-step explanation:
First, find the percentage of people that use the internet more than 15 hours per week.
[tex]\%=\frac{28}{50}=0.56=56\%[/tex]
Now, we can use this information to find 56% of 800.
[tex]56\%*800[/tex]
Note that percentages can also be written as that number over 100.
[tex]\frac{56}{100}*800=\frac{44800}{100}=448\text{ subscribers}[/tex]

Leonardo recorded his speed while skate-
boarding and determined he was traveling
18 feet per second. How many feet could
he travel in one minute?
Answer:
Leonardo was travelling: 1080 feet per min
Step-by-step explanation:
Since we know there are 60 seconds in a minute, we can just multiply 18 by 60 and get the answer as in the problem, it states that he is travelling 18 feet per second.
So the answer would be 18*60 or 1080 feet per minute.
There is a pair of parallel sides in the following shape.
What is the area of the shape?
Answer:
21
Step-by-step explanation:
It is a Trapezium so the formula will be 1/2 * (base 1 + base 2) * height
so 1/2 * ( 9+5) * 3
= 1/2 * 14 * 3
= 1/2 * 42
= 21

Step-by-step explanation:we look at the 3 in this and it is less than 5 and we only care about what is behind 0 in the ten thousand place. the 7 and 6 cannot add any more to the 3 to make a difference. So all in all it rounds down to 500,000. Hope it helps! ^w^
The figure below shows two half-circles at the ends of a rectangle with the dimension shown.
Which is closest to the area of the figure in square inches?
A. 75
B.95
C.106
D.154
Answer:
D. 154
Step-by-step explanation:
The area of the rectangle is 15*5= 75 inches
The area of the 2 semicircles combined, which make a circle, are:
π*r², where r is 5
r²=25
π*25=78.53981633
75 + 78.53981633 is about 154

see below:-
Step-by-step explanation:
Given,
[tex] \displaystyle{5 \frac{1}{6} + 2 \frac{1}{3} - 5 \frac{11}{12} }[/tex]
Convert the mixed fractions into improper fractions.[tex] \displaystyle{ \frac{31}{6} + \frac{7}{3} \ - \frac{71}{12} }[/tex]
Take LCM of the denominators:-LCM of 6,3 and 12=3×2×1×1×2=12[tex] \therefore{\displaystyle{ \frac{31}{6} + \frac{7}{3} - \frac{71}{12} = \frac{31 \times 2 + 7 \times 4 - 71 \times 1}{12} }}[/tex]
[tex] = \displaystyle{ \frac{62 + 28 - 71}{12} }[/tex]
[tex]\displaystyle{ = \frac{90 - 71}{12} }[/tex]
[tex]\displaystyle{ = \frac{19}{12} }[/tex]
Convert the improper fractions into mixed fraction:-[tex]\displaystyle{1 \frac{7}{12} }[/tex]
[tex] \quad\hookrightarrow\quad \sf {\dfrac{19}{12}\: or \: 1\dfrac{7}{12} }[/tex]
Ⲋⲟⳑⳙⲧⳕⲟⲛ :We will solve the given mixed fraction in 2 steps :
Converting into improper fraction[tex] \implies\quad \tt {5\dfrac{1}{6}+2\dfrac{1}{3}-5\dfrac{11}{12} }[/tex]
[tex] \implies\quad \tt { \dfrac{(6\times 5)+1}{6}+\dfrac{(3\times 2)+1}{3}-\dfrac{(12\times 5)+11}{12}}[/tex]

What are the vertices of A’B’C’ is ABC is dilated by a scale factor of 1/6?
Answer:
B
Step-by-step explanation:
we need to take each value in each ordered pair and divide it by 6:
A' = (12/6, 0/6) → (2,0)
B' = (18/6, 6/6) → (3,1)
C' = (6/6, 12/6) → (1,2)
Which ordered pair is on the graph of the equation 3x + 7y = 11?
(6, –1)
(1, –2)
(0,–4)
(0, 4)
Answer: (6, -1)
Step-by-step explanation:
Plug each pair in:
3(6)+7(-1)=11
11=11
True, so the first pair works.

Dante will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $63.96 and costs an additional $0.10 per mile driven. The second plan has an initial fee of $51.96 and costs an additional $0.15 per mile driven. How many miles would Dante need to drive for the two plans to cost the same?
answer: 240 miles
Answer:
Sir it says the answer at the bottom of the question
Step-by-step explanation:
It is 240 and I also did the math (.10 * 240 = 24 + $63.96 = 87.96)
and (.15 * 240 = 36 + 51.96 = 87.96) the answer is 240!

Frank paid $22.44 I sweatshirt had been discounted by 30% what is the regular price the sweatshirt
Answer: $32.06
Step-by-step explanation:
Let the regular price of the sweatshirt be x.
Therefore,
$22.44 = x - 0.3x
22.44 = 0.7x
x = about $32.06
Answer:
Step-by-step explanation:
22.44 represent 70% of the normal price of the sweatshirt.
Why 70%?
The reason is if you take 30% of the original price and subtract that from thirty %, you will get 70% of the original price.
Original price = 70% of x
Equation
70% x = 22.44
70/100 x = 22.44 Multiply both sides by 100
70 x = 22.44 * 100
70 x = 2244 Divide both sides by 70
70x/70 = 2244 / 70
x = 32.06
Answer: The sweatshirt originally cost 32.06

Helen Ming receives a travel allowance of $180 each week from her company for time away from home. If this allowance is taxable and she has a 24 percent income tax rate, what amount will she have to pay in taxes for this employee benefit?
Answer:
She has to pay $2246.4 in taxes for this employee benefit.
Step-by-step explanation:
First find the annual travel allowance equal to weekly allowance x 52 weeks = $180 x 52 = $9,360
When you get the annual travel allowance, find the annual tax.
Annual tax =Annual travel allowance × Tax rate
=$9,360 × 0.24
=$2,246.40
