A store has jeans on sale for 30% off. If the jeans
originally cost $40, how much will you spend on the jeans
after the discount and sales tax (8%)?
Answer:
$30.24!Step-by-step explanation:
Find the discounted price by setting up an equation
40-.3(40) AKA 30% of the original price is being taken off of the original price
Evaluate
40-12
$28 = discounted price
Sales tax is based on the reduced/discounted price* remember this
OF= multiplication (in this scenario)
.08x28
$2.24= sales tax
Add tax with discounted price
28+2.24=
$30.24!Solve for x in the diagram below.
Answer: 5x + (x + 54) = 6x + 54
So now 6x + 54 = 90 because u are solving a right angle.
90 - 54 is 36. So 6x = 36 and 36 divided by 6 is 6. Your answer for X = 6 Hope this helps you please mark brainliest

Working at a Restaurant in Downtown Charlotte:
Katie earns $77 for working 7 hours.
Matthew earns $92 for working 8 hours.
John earns $108 for working 9 hours.
Patrick earns $115 for working 10 hours.
Who has the highest hourly wage?
Answer:
John would have made the most per hour at 12$ per hour (no taxes included)

Emily wants to start a cell phone plan with AT&T. The company charges a set-up fee of
$39.99 and a monthly charge of $79.99 for the plan Emily wants to buy. Choose the
equation that models Emily's total cost C after m number of months.
C = 79.99 - 39.99m
O C = 39.99 + 79.99m
C = -79.99 - 39.99m
C = 79.99 + 39.99m
Answer:
39.99+79.99m
Step-by-step explanation:
She has to pay 39.99 and 79.99 times (m) months

Which pair of expressions is equivalent using the Associative Property of Multiplication?
Answer:
The pair of expressions in the options 'b' and 'c' is equivalent using the Associative Property of Multiplication.
Hence, options b and c are correct.
Step-by-step explanation:
The associative property of multiplication defines that when we multiply, we can group the numbers in any combination.
a × (b × c) = (a × b) × c
For example,
4 × (6 × 8) = (4 × 6) × 8
In our case, now, if we analyze the options 'b' and 'c'
5 (3a · 4) = (3a · 4) · 5
5 (3a · 4) = (5 · 3a) · 4
It is clear that both the expressions are equivalent using the Associative Property of Multiplication as we have discussed earlier.
Thus, the pair of expressions in the options 'b' and 'c' is equivalent using the Associative Property of Multiplication.
Hence, options b and c are correct.

Answer: The number is 14 , look into the steps for more explanations.
Step-by-step explanation:
Twice the sum of a number and seven is three times the number .
in this case we will represent that number by the variable x.
The sum of x and 7 is x+7
Twice that will be 2(x +7)
That has to equation three times the number which will make it
2(x+7) = 3x Now solve for x to find the number by distributing
2x + 14 = 3x Subtract 2x from both sides
2x -2x
14 = 1x Divide both sides by 1
x = 14

A 4 metre long ladder is placed against a wall. The angle between the ladder and
the ground is 75°. How far up the wall does the ladder reach?
How do you do this?
Answer:3.86 m
Step-by-step explanation:
Given
Length of ladder L=4 m
angle made by ladder and the ground is [tex]\theta=75^{\circ}[/tex]
we will use trigonometry here
from the figure, we can write
[tex]\sin 75^{\circ}=\dfrac{x}{L}\quad [\text{where, x=distance of the ladder from the ground}][/tex]
[tex]\Rightarrow x=L\sin 75^{\circ}\\\Rightarrow x=4\sin 75^{\circ}=3.86\ m[/tex]
Mike paid $32 for a sult Jacket that had been marked down 40% from its original price, What was the original price.
Answer:
The answer is $44.80
Step-by-step explanation: First, you need to find the how much 40% of $32 is:
32 x .40 = 12.80
Then, you add 12.80 to $32.
$32 + $12.80 = $44.80
Answer: 44.8$
Step-by-step explanation:
What you have to do is find 40% of 32. (it is 12.8) add 12.8 to 32. You get 44.8

is it possible for an object to have more than one input value, but only one output value
Answer:
We conclude that it is possible for an object to have more than one input value, but only one output value.
Step-by-step explanation:
Yes, it is possible for an object to have more than one input value, but only one output value.
For example, considering the table having 'name' as the 'input' and the output as 'age'.
Name of Relatives Age (years)
Mr A 13
Mr B 14
Mr C 13
Mr D 15
Here, Each input has only input. But, multiple relatives can have the same age.
Here, Mr A and Mr C have the same 13 years age. This table represents a function.
Therefore, we conclude that it is possible for an object to have more than one input value, but only one output value.

A woman begins planting her garden at 10:20 am. It takes her 5 ! "# hours to finish getting all of her flowers planted. She needs to shower and get ready for a dinner engagement at 5 pm. If her she needs 1 $ % hours to shower and get ready, will she make it on time?
Answer:
She will be ready, and she will make it on time.
Step-by-step explanation:
Given:
[tex]Start\ Time = 10:20\ am[/tex]
[tex]Planting = 5\ hours[/tex]
[tex]Shower = 1\ hour[/tex]
Required
Will she be ready by 5pm?
First, we calculate the time spent in planting and taking shower.
[tex]Time\ Spent = Planting + Shower[/tex]
[tex]Time\ Spent = 5\ hours + 1\ hour[/tex]
[tex]Time\ Spent = 6\ hours[/tex]
Next, we calculate the end time. i.e. the time she'll finish these tasks.
[tex]End\ Time=Start\ Time + Time\ Spent[/tex]
[tex]End\ Time=10:20\ am + 6\ hours[/tex]
[tex]End\ Time=04:20\ pm[/tex]
Since 04:20 pm is less than 5pm, then she will be ready, and she will make it on time.
Here is a rectangle ABCD.
A
B
20 cm
D
30 cm
The length of the rectangle is increased by 10%.
The width of the rectangle is increased by 5%.
Find the percentage increase in the perimeter of the rectangle.
answer
15.5%
Step-by-step explanation:
length = 30
30+10%=33
breadth=20
20+5%=21
area of rectangle = length × breadth
600² centimeters = 30 × 20
693² centimeters = 33 × 21
Increase = 15.5%
Sara needs to buy a gallon of milk for $3.98, a dozen eggs for $2.75, and paper towels for $3.87. Sara said she needs $10 to pay for all the items. Is her answer reasonable? *
Answer:
No
Step-by-step explanation:
$3.98 + $2.75 + $ 3.87 ≠ $10

apply the distributive property to write an equivalent expression 21b + 28c
Answer:
7(3b + 4c)
Step-by-step explanation:
21b + 28c
First, find the common factor of the coefficients (21 and 28).
GCF is 7.
Next, divide out 7 from the equation.
(21b + 28c)/7 = 3b + 4c
Now put the 7 outside of the parenthesis.
7(3b + 4c)
