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?
Answers
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]
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
Answers
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!

Step-by-step explanation:
We can solve this question by using the method of finding the square root.
The given equation is:
[tex]8x ^ { 2 } -3=2[/tex]
Add 3 to both the sides of the equation.
[tex]8x^{2}=2+3[/tex]
Now, add 2 & 3 to get 5.
[tex]8x^{2}=5[/tex]
Dividing both the sides of the equation by 8, we get...
[tex]x^{2}=\frac{5}{8}[/tex]
Now, take the square root of both the sides of the equation...
[tex]x =\sqrt{ \frac{ 5 }{ 8 } } \\x = \frac{\sqrt{5}}{\sqrt{8}} \\[/tex]
Rationalize the denominator.
[tex]x = \frac{\sqrt{5}}{2\sqrt{2}} \\x = \frac{\sqrt{5}\sqrt{2}}{2\left(\sqrt{2}\right)^{2}} \\x = \frac{\sqrt{5}\sqrt{2}}{2\times 2} \\x = \frac{\sqrt{10}}{2\times 2} \\x = \boxed{ \frac{\sqrt{10}}{4} , - \frac{\sqrt{10}}{4} }[/tex]
[tex]\rule{200}{3}[/tex]
The value of x = [tex]\boxed{ \frac{\sqrt{10}}{4} , - \frac{\sqrt{10}}{4} }[/tex][tex]\rule{200}{3}[/tex]

VI) You finally purchased a backup oxygen tank needed for the base which originally cost
$50,000 on sale for $18,000. (3 points)
a) How much did you save?
b) What fraction of the original price was this?
c) What % of the original price was this?
Answers
Answer:
a) $32,000
b) 9/25
c) 36%
Step-by-step explanation:
Hello!
A) How much did you save?
Let's see. In order to find the savings, we must subtract the new price from the original.
50,000 - 18,000 = 32,000You saved $32,000 (a pretty good deal!)
B) What fraction of the original price was this?
To find the fraction, we must divide the new price from the original.
18,000/50,0009,000/25,000 => SImplify9/25 => SimplifyIt's 9 twenty-fifths of the original price.
C) What fraction of the original price was this?
Convert the fraction to percent

When you get the annual travel allowance, find the annual tax.
Annual tax =Annual travel allowance × Tax rate
=$9,360 × 0.24

Dana is given the total surface area of a rectangular pyramid. She is asked for the lateral surface area. Describe how Dana can use the given information to determine the lateral surface area.
Answers
To get the lateral surface area, dana will subtract the two base area from the total surface area.
Total surface area of rectangular prism
The total surface area of a rectangular prism is the sum of the areas of all of the faces or surfaces that enclose the solid. Therefore,
2lw + 2wh + 2lhwhere
l = length
w = width
h = height
Lateral surface area of a rectangular prismThe lateral surface area of a rectangular prism is the surface area of the solid without the bases.
Therefore,
LA = 2 ( l + w ) hTotal surface area = Lateral surface area + 2 (Base Area)
Total surface area = 2 (l + w) h + 2 (l x w) = 2lh + 2wh + 2lw
Therefore,
Lateral surface area = Total surface area - 2 (Base Area)
To get the lateral surface area, dana will subtract the two base area from the total surface area.
