Answer:
y = -52x + 480
Step-by-step explanation:
Let us assume the number of pages left be x
And, the number of hours is x
According to the question
Data given is as follows
Number of hours 1.5 and 5
Total pages 480
Left pages 402
Based on the above information,
The computation is shown below;
Pages read by Shriya in 1.5 hours is
= Total pages in the book - left pages to read
= 480 pages - 402 pages
= 78 pages
And, there is 1.5 hours
So in one hour she read
= 78 pages ÷ 1.5 hours
= 52 pages per hour
So, the equation is
y = -52x + 480
Solve for x: 8 ≥ 5 - 12x
is 85 a composite number and why
Answer It is composite number
Step-by-step explanation:
A composite number is a number that can be divided evenly by more numbers than 1 and itself. ... Since 85 cannot be divided by just 1 and 85, it is a composite number.
Hey there! :)
85 is composite.
All numbers that have more than 3 factors are composite numbers because they are 'composed' of some smaller numbers.
Hope this helps!

Round the numbers to estimate the quotient. 29 and one-fifth divided by 4 and StartFraction 6 over 7 EndFraction Which numbers should be used? 25 ÷ 5 The estimated quotient is
Answer:
The quotient is 6.
Step-by-step explanation:
Given two fractions are:
[tex]29\dfrac{1}{5}[/tex]
and
[tex]4\dfrac{6}7[/tex]
To find:
The quotient of
[tex]29\dfrac{1}{5}\div 4\dfrac{6}7[/tex]
Solution:
Formula to convert mixed fraction to a fraction:
[tex]p\dfrac{q}{r} = \dfrac{p\times r+q}{r}[/tex]
Using the above formula to rewrite the given mixed fractions:
[tex]29\dfrac{1}{5}[/tex] can be written as:
[tex]\dfrac{29\times 5+1}5\\\Rightarrow \dfrac{146}{5}[/tex]
[tex]4\dfrac{6}7[/tex] can be written as:
[tex]\dfrac{4\times 7+6}{7}\\\Rightarrow \dfrac{34}{7}[/tex]
Now dividing:
[tex]\dfrac{\frac{146}{5}}{\frac{34}{7}}\\\Rightarrow \dfrac{146\times 7}{5\times 34}\\\Rightarrow \approx 6[/tex]
Therefore the quotient is 6.

During a winter storm, a ski resort received 9 inches of snow in 12 hours. The snow fell at a steady rate. How many inches of snow fell at each hour.
Answer:
0.75 inches of snow
Step-by-step explanation:
During a winter storm, a ski resort received 9 inches of snow in 12 hours. The snow fell at a steady rate. How many inches of snow fell at each hour.
12 hours = 9 inches of snow
1 hour = x
Cross Multiply
12 hours × x = 1 hour × 9 inches
x = 9/12
x = 0.75 inches
Therefore, 0.75 inches of snow fell at each hour.

A'Reana earns a weekly allowance for doing chores around the house and for keeping all of her grades above a C. During a particular week, she gave $10 to her friend Taylor, spent half of the remaining money on a new shirt, and then spent $7.50 on a pizza. At this point, she had $37.50. How much is A'Reana's weekly allowance?
Given :
During a particular week, she gave $10 to her friend Taylor, spent half of the remaining money on a new shirt, and then spent $7.50 on a pizza. At this point, she had $37.50.
To Find :
How much is Reana's weekly allowance.
Solution :
Let, allowance is x.
Then by given conditions :
37.50 = x - ( 10 + x/2 + 7.50 )
37.50 = x/2 - 17.50
x/2 = 55
x = $110
Therefore, Reana's weekly allowance is $110.
Hence, this is the required solution.

Thurman put $90 into an account that pays 4.4% interest, compounded quarterly. According to the rule of 72, approximately how long will it take for his money to double?
Answer:
Number of Years to Double= 15.65
Step-by-step explanation:
Giving the following information:
Interest rate= 0.044/4= 0.011
Annual compound interet rate= (1.011^4) - 1= 0.4473
The rule of 72 is a means of estimating the number of years it takes for an investment or your money to double.
Number of Years to Double= 70/Annual Rate of Return
Number of Years to Double= 70/4.473
Number of Years to Double= 15.65

Three friends bought 4, 6, and 8 books.
This table shows the cost of the books.
Number of Books 4 6 8
Cost ($) 30 45 60
What is the constant of proportionality?
A. 2
B. 7.5
C. 15
D. 30
Answer:
B:7.5
Step-by-step explanation:
since 4 goes with 30, 6 goes with 45, and 8 goes with 60, you can see that 60-45 is 15 and 45-30 is 15 as well so the constant is 15, but the number of books is going up by two so the constant there is 2. So divide 15 by 2 and the answer would be C: 7.5.
Answer:
B. 7.5

Answer:
3.Joan has too many squares for an 11-foot-by-11-foot quilt and not enough squares for a 12- foot-by-12-foot quilt.
Step-by-step explanation:
Given that:
Joan sewed 115 fabrics for her new quilt and each fabric square was 12 by 12 inches, suppose no fabric square was cut or folded, the largest quilt Joan could make was an 11-foot-by-11-foot quilt but not enough squares for a 12- foot-by-12-foot quilt.
Different nerve signals travel at different speeds. Pressure and touch signals travel about 250 feet per second. Dull pain signals travel about 2 feet per second. How long does it take you to feel an ant crawling on your foot? Write your answer in a sentence using context. How much longer does it take to feel a dull ache in your foot? Write your answer in a sentence using context.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Pressure and touch signal speed = 250 feets per Second
Dull pain signal speed = 2 feets per second
Ant crawling on foot
A crawling ant on one's feet can be attributed to a touch signal, hence it will take ;
Time = Distance / speed
(Distance moved by crawling ant / 250)
(Dull ache in foot) = 250 / 2 = 125
It takes 125 times longer to feel a dull ache in foot.

Answer:
x = 16 y = 22.627 (or 16[tex]\sqrt{2[/tex])
Step-by-step explanation:
cos(45) = 16/y
y = 16/cos(45)
y = 22.627
tan(45) = 16/x
x = 16/tan(45)
x = 16
*this can also be found because we know this is a right triangle with two angles of 45 degrees. This means that both sides will be equal so x will be 16 and the diagonal will be 16 root 2 (22.627)

A circle has circumference 200 pi feet.
What is the radius of the circle?
Answer: The diameter is two times the radius, so the equation for the circumference of a circle using the radius is two times pi times the radius. If you are given the circumference but not the radius or the diameter, you can still solve for one or the other using these formulas.
Step-by-step explanation:
The radius of the circle which has a circumference of the cirlce of 200π will be 100 feet.
What is the circumference of a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. The circumference of the circle will be
C = 2πr units
The circumference of the circle is given as 200π feet. Then the radius of the circle is given as,
200π = 2πr
Simplify the equation, then the value of the variable 'r' will be given as,
200π = 2πr
r = 100 feet
The radius of the circle which has a circumference of the cirlce of 200π will be 100 feet.
