The sales tax in Sandra's town is 6.5%. If she buys 2 shirts for $23.99 each and a pair of shoes for $41.99, how much sales tax does she owe?
4.68
5.84
7.85
5.12
Answer:
5.84
Step-by-step explanation:
She has two shirts and their 23.99 each
23.99 x 2 = 47.98
Then she has a pair shoes that cost 41.99
Add
47.98 + 41.99 = 89.97
6.5% = 0.065
89.97 x 0.065 = 5.84

You have twenty blankets that each take up 704 cubic inches of space. How many blankets could you pack into a 22-inch moving box?
Answer:
32
Step-by-step explanation:
i don't know if its right but i did 704 divided by 22 which equals to 22
We can pack a maximum of 15 blankets into the 22-inch moving box.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To determine how many blankets can fit in a 22-inch moving box, we first need to calculate the volume of the box.
Since the box is 22 inches in all three dimensions (length, width, and height), its volume is:
= 22 x 22 x 22
= 10,648 cubic inches
Next, we need to divide the volume of the box by the volume of one blanket to find out how many blankets can fit inside.
= 10,648 / 704
= 15.125
We can't fit a fraction of a blanket, so we can only pack a whole number of blankets.
Therefore,
We can pack a maximum of 15 blankets into the 22-inch moving box.

what is
the equation of the line that passes through the points (-6,6) and (-1,-9)
Answer:
The answer to the question provided is y = -3x - 12.
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ☟
[tex]y = mx + b[/tex]
❃Incase you also forgot, what the slope formula is ☟
[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]
➊ First: We are going to be solving for the slope.
[tex]m = \frac{ - 9 - 6}{ - 1 - ( - 6)} = \frac{ - 15}{ \: \: \: 5} = - 3[/tex]
➋Second: We find the y-intercept.
[tex]y = mx + b \\ 6 = - 3( - 6) + b \\ 6 = 18 + b \\ \frac{ - 18 = - 18 \: \: \: \: \: \: \: \: \: \: \: \: }{ - 12 = b}[/tex]

If 38% of a number, n, is 24.32, what is 20% of n?
Answer:
20 % of n would be 12.8
Step-by-step explanation:
By first finding that 24.32 is 38% of 64. To find that you would have the fractions 38/100 = 24.32/n. From there you cross multiply the 100 times 24.32 then divide that answer by 38 to get the answer 64. you take that n=64 and find 20% of that which is 12.8.
The 20% of n is 12.8
38% of number n is given as:
[tex]38\% \times n = 24.32[/tex]
Express the percentage (38%) as decimal
[tex]0.38 \times n = 24.32[/tex]
Divide both sides of the equation by 0.38
[tex]n = 64[/tex]
Multiply both sides of the equation by 20%
[tex]20\% \times n = 20\% \times 64[/tex]
Express the percentage (20%) as decimal
[tex]20\% \times n = 0.20 \times 64[/tex]
Evaluate the product
[tex]20\% \times n = 12.8[/tex]
Hence, the 20% of n is 12.8

Lisa sold 11 shirts for every 7 shirts Becky sold. If the girls sold 72 shirts in all, how many shirts did Becky sell?
Answer: 28 shirts
Step-by-step explanation:
From the question, we are informed that Lisa sold 11 shirts for every 7 shirts Becky sold. This can be expressed in a fraction as:
Lisa = 11/(11 + 7) = 11/18
Becky = 7/(11 + 7) = 7/18
If the girls sold 72 shirts in all, the number of shirts sold by Becky will be:
= 7/18 × 72
= 7 × 4
= 28

no, they are not equivalent expressions
Step-by-step explanation:
simplify: -3(6a - 5) + 4a = -3(6a) + (-3)(-5) + 4a = -18a + 15 + 4a = -14a + 15

Mai bought a television for $350. The tax rate is 8%. What is the total amount Mai paid for the television?
Answer:
378
Step-by-step explanation:
We know that she bought a television for $350 and the tax rate is 8%. This means the equation will be 350+(0.08*350). We can solve that equation using benchmark fractions since that's the quicker method of doing it.
To find 8% of 350, we can do 1% of 350 = 3.5 and we just multiply 3.5*8 which is 28. So we do 350+28.
You could also do 350*.08 but that's less efficent

The diagonal of a rectangular swimming pool measures 29 yards. If the length of the pool is 25 yards, which measurement is closest to the width of the pool?
Answer:
Width of the pool = 15 yards
Step-by-step explanation:
Given that:
Length of diagonal of swimming pool = 29 yards
Length of the pool = 25 yards
Let,
w be the width.
This will form a right angled triangle where the diagonal will be hypotenuse.
Using Pythagorean theorem;
[tex](25)^2+(w)^2 = (29)^2\\625+w^2=841\\w^2= 841 - 625\\w^2 = 216[/tex]
Taking square root on both sides
[tex]\sqrt{w^2}=\sqrt{216}\\w=14.70[/tex]
Rounding off to nearest whole number
w = 15 yards
Hence,
Width of the pool = 15 yards

What is Percentage?A percentage is a portion of a whole number which is expressed as a number between the range of 0 and 100 rather than as a fraction. All of a thing is 100 percent, half of it is 50 percent, and none of something is zero percent. To determine a percentage, we divide the portion of the whole through the whole of itself and multiply it by 100.
x × 150/100 = 12
x = 12 × 100/ 150
x = 1200/ 150
x = 8
x × 50/100 = 5
x = 5 × 100/ 50
x = 500/ 50
x = 10
x × 10/100 = 300
x = 300 × 100/ 10
x = 30000/ 10
x = 3000
x × 5/ 100 = 72
x = 72 × 100/ 5
x = 7200/ 5
x = 1,440
x × 80/ 100 = 20
x = 20 × 100/ 80
x = 2000/ 80
x = 25
Therefore, the values of unknown numbers are 8, 10, 3000, 1440, and 25, respectively.
