Answer: She needs 10 1/2 hours to read the book.
Step-by-step explanation:I day = 1 3/4 hours
6 days = 1 3/4 x 6
6 days = 7/4 x 6
6 days = 42/4
6 days = 10 1/2 hours
The perimeter of a parallelogram must be no less than 40 feet. The length of the rectangle is 6 feet. What are the
possible measurements of the width?
a. Write an inequality to represent this problem. Use w to represent the width of the parallelogram. (Hint: The formula
for finding the perimeter of a parallelogram is P = 21 + 2 w.
b. What is the smallest possible measurement of the width? Justify your answer by showing all your work.
Step-by-step explanation:
If you know that your perimeter must be no less than 40 feet, you can say that P >= 40 ft. Since P is given by P=2l+2w, you can combine the two equations into a single inequality:
2l+2w >= 40
If the length is given by 6 feet, then you can further simplify the inequality to be
12+2w >= 40 --> w >=14

Step-by-step explanation:
The sum of two numbers is 72, and their difference is 40. Find the numbers.
Answer:
56 and 16
Step-by-step explanation:
Set up equations!
x+y=72
x-y=40
You can solve for this by crossing out y as it becomes eliminated. You are left with 2x= 112. Then solve, so x= 56. Take 56 for x and plug it into one of the equations and solve for y. 56-y=40-----> y= 16. The numbers are 16 and 56.
Using a system of equations, it is found that the numbers are 16 and 56.
The numbers are unknown, so we are going to call them x and y.Their sum is of 72, thus:
[tex]x + y = 72 \rightarrow y = 72 - x[/tex]
Their difference is of 40, thus:
[tex]x - y = 40[/tex]
Since [tex]y = 72 - x[/tex]
[tex]x - (72 - x) = 40[/tex]
[tex]2x = 112[/tex]
[tex]x = \frac{112}{2}[/tex]
[tex]x = 56[/tex]
Then:
[tex]y = 72 - x = 72 - 56 = 16[/tex]
The numbers are 16 and 56.

Whitney deposits $9,000 for two years. She compares two different banks. State Banks will pay her 4.1% interest, compounded monthly. Kings Savings will pay her 4.01% interest, compounded continuously.
Answer:
1)state bank
2)$16.21
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW
Whitney deposits $9,000 for two years. She compares two different banks. State Banks will pay her 4.1% interest, compounded monthly. Kings Savings will pay her 4.01% interest, compounded continuously.Which bank pays higher interest? How much higher?
The Amount in the formula for compound interest is
A= P(1+r)^2
P = principal amount,
r = rate per periods,
t = number of periods,
To know the interest she got from the State bank, we say
P = $ 9000, r = 4.1% = 0.041, t = 2 years,
A= 9000(1+0.041)^2
A= 9000(1.041)^2
= 9767.74
Then interest earned = A - P
= 9767.74 - 9000
= $ 767.74
To know the interest she got from the State bank, we say
P = $ 9000, r = 4.01% = 0.0401, t = 2 years,
A= 9000(1+0.0401)^2
A= 9000(1.0401)^2
= 9751.53
Then interest earned = A - P
= 9767.74 - 9000
= $ 751.53
The difference between the two interest is ($ 767.74 - $ 751.53)
=$16.21
Hence state bank will have $16.21 higher interest
A chef makes a fruit salad using pears and mangos. Pears and mangos each cost $2.25 per fruit. The chef buys x pears and y mangos. Which two expressions represent the chef's cost of making the fruit salad?
Answer:
P=2.25x-----------1
M=2.25y----------2
Step-by-step explanation:
Step one:
given data
we are told that the cost of pears= $2.25 each
and cost of mango= $2.25 each
Step two:
the chef bought x pears and y mangoes
let the total cost of pears be P
and for mango be M

An airplane cuts through the morning sky for every 1,000 feet that he climbs the outside temperature drops 20° f what is the rate of the temperature change in degrees Fahrenheit per foot complete the steps below to answer the question
Given :
An airplane cuts through the morning sky for every 1,000 feet that he climbs the outside temperature drops 20° F.
To Find :
The rate of the temperature change in degrees Fahrenheit per foot.
Solution :
Let, rate of the temperature change in degrees Fahrenheit per foot is x.
So,
[tex]x = \dfrac{20}{1000}\ ^oF/foot\\\\x = 0.02 ^oF/foot[/tex]
Therefore, rate of the temperature change in degrees Fahrenheit per foot is 0.02.
Hence, this is the required solution.
Answer:
this is really late, but for the people who need it now the real answer is
Step-by-step explanation:
The airplane is rising, so the change in elevation is +1,000 feet. The temperature is dropping, so the change in temperature is -20 degrees Fahrenheit.

A sport shop has 30 employees. 80% of the employees work part time. How many part-time employees does the sports shop have?
Answer:
they have 24 part time employees
Step-by-step explanation:
multiply 30 by .8 (which is 80% in decimal form) and you get 24. subtract that from 30 and you get 6 extra employees. 24 is the answer.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
100% = 30
80% = 24
The number of employees who work part-time is 24.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of employees = 30
80% of the employees work part-time.
This means,
80% of 30
= 80/100 x 30
= 24
Thus,
The number of employees who work part-time is 24.

Answer:
La oferta 2 oferce el mayor valor final. Es la que debería ser aceptada.
Step-by-step explanation:
Dada la siguiente información:
Oferta 1:
$150.000 hoy y $200.000 dentro de 10 años.
Oferta 2:
$30.000 al final de cada uno de los próximos 10 años.

Para decidir cuál de las dos ofertas es mejor, debemos calcular el valor final:
Oferta 1:
VF= VP*(1+i)^n
VF= 150.000*(1,14^10) + 200.000
VF= $2.261.523,48

The equation that represents the canned goods order is
24x + 4y = 384, where x = number of minutes spent
producing fruit cans, and y = number of minutes
producing vegetable cans.
If the vegetable assembly line runs for 3 minutes, how
many minutes would the fruit assembly line need to run to
complete the order of 384 cans? Explain
Answer:
8 minutes.
Step-by-step explanation:
24x + 64y = 384, that represents the canned goods order .
where x = number of minutes spent producing fruit cans,
and y = number of minutes producing vegetable cans.
If the vegetable assembly line runs for 3 minutes, then put y=3 in equation we get
Therefore, the fruit assembly line need to run to complete the order of 384 cans in 18 minutes.
Answer:
Substitute 3 into the equation for y. Solve for x and find that x = 8. So if cans of vegetables are processed for 3 minutes, fruit needs to be processed for 8 minutes to complete the 384-can order.
