Answer:
x-35.75=40.00
Step-by-step explanation:
Let's use m as our variable.
So Marlen went to the mall and spent $35.75 on shoes. When she got home she had $40.00 in her purse.
An equation to represent this is : x-35.75=40.00
If you are interested in the value of x it is $75.75

1+n/7=3
A. Do the reciprocal of 1/7
B. Divide both sides by 7
C. Multiply both sides by 7 for the inverse
D. Subtract 1 on both sides for the inverse
Answer:
C.
Step-by-step explanation:
I'm assuming that the equation is (1+n) / 7 = 3, where 1+n is the numerator and 7 is the denominator.
In this case, to isolate for n, you have to multiply both sides by 7.
then you get 1+n = 3/7, and then you can get n = 3/7 - 1

A piece of string is 3-5 m long. Joe cuts three pieces from it,
each 70 cm long. How much of the original piece is left?
Note: It seems you mean a piece of string is 3.5 long. So, I am assuming that a piece of string is 3.5 cm long.
Answer:
140 cm of the original piece is left after Joe cuts three pieces.
Step-by-step explanation:
Given the piece of string
3.5mAs we know that
3.5m = 350 cmso the length of a piece of string = 350 cm
As joe cuts three pieces from it, and each 70 cm long.
so the total length of three pieces which were
cut by joe = 70cm + 70cm + 70cm = 210 cm
So, subtracting the total length of the three pieces that were cut from the total length of the string:
350 cm - 210 cm = 140 cm
Therefore, 140 cm of the original piece is left after Joe cuts three pieces from it.

Step-by-step explanation:
For a standard normal distribution, find:______. P(z < -0.34) Express the probability as a decimal rounded to 4 decimal places.
Answer:
36.69%
Step-by-step explanation:
Given a standard normal distribution :
P(Z < - 0.34) :
Using the Z distribution table :
Look up the value - 0.3 down the row and 0.04 a cross the column. The value at the intersection of the two points gives the required proportion:
P(Z < - 0.34) = 0.3669
0.3669 as a percentage = 0.3669 * 100% = 36.69%
The value can also be obtained using the Z probability calculator.

month. At CellCoB, Paul can purchase the same phone for $350 and get an unlimited calling plan for $30 per month. In how many months
will both plans cost the same?
These equations, which are graphed below, represent the situation.

Answer:

13. $988,881.23
14. $7,762.93
15. $8,686.16
16. $967,647.66
Step-by-step explanation:
The annuity and amortization formulas are used for problems like this.
sum of monthly payments = P((1 +r/12)^(12t) -1)/(r/12)
monthly amount available = P(r/12)/(1 -(1 +r/12)^(-12t))
__
12. The sum of monthly payments of 74, accumulated at 9% compounded monthly for 52 years is ...
A = ($74)((1 +.09/12)^(12·52) -1)/(.09/12) = $1,035,057.23
__
13. The total of payments is ...
$74×12×52 = $46,176
So, the interest earned is ...
$1,035,057.23 -46,176 = $988,881.23
__
14. The amount available in perpetuity is the monthly interest on this account balance.
$1,035,057.23 × .09/12 = $7,762.93
__
15. The monthly amount available for 25 years is found from the amortization formula:
A = $1,035,057.23(.09/12)/(1 -(1 +.09/12)^(-12·25)) = $8686.16
__
16. The amortization formula is used for this, too.
8066 = P(.094/12)/(1 -(1 +.094/12)^(-12·30)) = 0.00833568P
P = $8066/0.00833568 = $967,647.66
Find the total amount given the original price, tax rate and tip rate. Round to the nearest hundredth if necessary.
Original price: $101.33
Tax rate: 6.7%
Tip: 18%
Answer:
The total cost would be $126.36
Step-by-step explanation:
18% plus 6.7% is 24.7%. 24.7% of 101.33 is 25.028. Add $101.33 and $25.03
The total amount including tax rate and tip rate is $127.58.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The original price is $101.33.
Now, Tax rate is 6.7%.
Price with tax is,
= (106.7/100)×101.33.
= $108.12.
The price with tip is,
= (118/100)×108.12.
= $127.58.
So, The total price is $127.58.

Anthony drew a picture of the front view of a doghouse using two congruent triangles and a rectangle, as shown in the diagram. 3 in. 4 in. 12 in. What is the area of the picture of the doghouse in square inches?
Answer:
66 in.
Step-by-step explanation:
the rectangle has an area of 48in. because 4x11 = 48. The triangles have a base of 6 because 12 ÷ 2=6. the formula for area of a triangle is BxHx1/2 and the height is 3in so 6x3= 18 and 18x1/2=9 and there is two triangles and the other has the same area. Then you add up the area of everything so 48+9+9 = 66

Suppose the class sizes in high schools in a major public school district are normally distributed with an unknown population mean and standard deviation. If a random sample of 28 high school classes is taken to estimate the mean class size, use a calculator to find the t-score that should be used to find a 90% confidence interval estimate for the population mean.
Answer:
1.703
Step-by-step explanation:
The reason we try to find t score is because the sample size is below 30, meaning the sample size is small
Hence:
Step 1
We find the degree of freedom
The Degrees of freedom = Number of samples - 1
The random number of samples = 28
= 28 - 1
= 27
Step 2
Using a t score table or t score calculator, we can obtain the t score value for a 90% confidence interval and degree of freedom of 27
90% confidence interval =
10% significance level = 0.10 for two tails or 0.1/2 = 0.05 for one tail
Hence: t90 = 1.703
A local grocery store received a new shipment of apples. The apples arrived in 8 crates with 20 apples in each crate. If the store pays $0.21 per apple and sells each apple for $0.79, what would the profit be after selling all of the apples?
A.
$16.24
B.
$22.12
C.
$92.80
D.
$126.40
The correct answer is C. $92.80
Explanation:
The first step is to calculate the profit for each apple, this can be found by subtracting the cost the store pays from the selling price.
$0.79 - $0.21 = $0.58
This means for each apple the store sold, the profit (amount of money earned) is $0.58. Now, let's find the total apples the store received, and therefore the total of apples the store can sell.
8 creates each with 20 apples
8 x 20 = 160 apples
Finally, multiply the profit for selling one unit by the total apples
160 x 0.58 = $92.8
Alfonso made a scale drawing of a tower. The actaul height of a tower is 25 feet. The scale Alfonso used in his drawing is 1 in.:10 ft. What is the height of the tower in Alfonso's drawing?
Answer:
2.5 inches
Step-by-step explanation:
Using Alfonso's scale of the drawing, which is 1in=10 ft, we can conclude the height of the tower to be 2.5 inches because
the actual height of the tower is 25 feet
10+10=20, which by following the scale, is 2 inches
we then have 5 left, 5 being half of 10, and .5 being half an inch.
Therefore the height of the tower using Alfonso's scale is 2.5 inches.
Hope this helps and take care
