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

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

Serena is hitting golf balls at the driving range. When she hit a ball with her 9-iron, it stopped x yards in front of the 100-yard marker. She knows she can hit a ball twice that far if she uses her driver. Complete the steps below to see how far Serena can hit a golf ball with her driver.
Write an expression in terms of x that represents the distance Serena hit the golf ball using her 9-iron.
Serena knows she can hit a golf ball two times as far with her driver as with her 9-iron. Write an expression in terms of x to represent how far Serena can hit a ball using her driver.
Use the Distributive Property to expand the expression you obtained in part B.
Let’s try something a bit different. Serena hit a ball 2x yards past the 150-yard marker with her 3-iron. Write an expression in terms of x that represents this distance.
Now use the Distributive Property to factor the expression you obtained in part D.
Why do you think the operation that you performed on the expression in part E is called factoring? Use what you know about factoring numbers.

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

Jennifer borrowed $720 for a new TV. She has paid 3/4 of the debt. how much does she still owe?
Answer: yes the answer is 2:5 it isn’t right in just saying sum things
Step-by-step explanation:
The Quick Ship company uses the function C(w) to calculate the cost in dollars, C, for shipping an item
weighing w ounces.
5 0.450 if 0
C(w) =
0.35W + 1.6 if w > 16
Which statement about the shipping rate is true?
Shipping at the second rate will always cost $1.60 more than shipping
at the first rate.
If the weight is greater than 16 ounces, the shipping rate is $0.35 per
ounce, plus $1.60.
It is possible that an item weighing less than 16 ounces could cost the
same as an item weighing more than 16 ounces.

Answer:
A: Shipping at the second rate will always cost 1.60 more than shipping at the first rate.
Step-by-step explanation:
The following points for the function C(w) can be concluded as
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that the Quick Ship company uses the function C(w) to calculate the cost in dollars {C} for shipping an item weighing {w} ounces as
C(w) = 0.35W + 1.6 if {w > 16}
The given function is -
C(w) = 0.35w + 1.6 if {w > 16}
We can conclude the following points for the function C(w) -
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.Therefore, the following points for the function C(w) can be concluded as

Find each unknown number. a. 12 is 150% of what number? b. 5 is 50% of what number? c. 10% of what number is 300? d. 5% of what number is 72? e. 20 is 80% of what number?
The unknown values of number for each of the expression is 8, 10, 3000, 1440, and 25.
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.
