Answer:
Step-by-step explanation:
Let x be last year's salary.
100%x + 8/100 x = 40120
100x/(100) + 8/100x = 40120
108x/100 = 40120
1.08x = 40120
x = 40120/1.08
x = 37148.14
Now if you take 8% of 37148.14 = 2971.85
And add it to 37148.14
You should get the current earning 40119.99
You are within a penny of the same answer. This question will not work out evenly because 1.08 does not divide evenly into 40120.

n is an integer and - 2<n+3<4, write down the possible values of n from smallest to largest
Answer:
- 4, - 3, - 2, - 1, 0
Step-by-step explanation:
Given
- 2 < n + 3 < 4 ( subtract 3 from each interval )
- 5 < n < 1
This indicates that n ≠ - 5, 1 but all values in between, that is
n = - 4, - 3, - 2, - 1, 0 ← possible values of n

1. The length of a rectangle is 4 meters less than
twice its width. The area of the rectangle is
70 m2. Find the dimensions of the rectangle.
Answer:
length is 10, width is 7
Step-by-step explanation:
Area of a rectangle = length * width = lw
Area is known to be 70
length = twice width - 4 = 2w-4 = l
width=w
so A = lw = (2w-4)w = 70
(2w-4)w=70
2w^2-4w=70
2w^2-4w-70=0, divide by 2
w^2 - 2w - 35 = 0, not sure how your class solves these, I see visually
(w-7)(w+5)=0
w=7 or w=-5, -5 makes no sense in the real world (negative length), so w=7
l = 2w-4 = 2(7)-4 = 14-4 = 10

What is the proportion of 36 / x equals 8/7
Answer:
Step-by-step explanation:
Multiply all terms by the same value to eliminate fraction denominators
36/x=8/7
x times 36/x=x times 8/7
Cancel multiplied terms that are in the denominator
cancel both x’s for you should have 36=x times 8/7
Combine multiplied terms into a single fraction
36=8x/7
Multiply all terms by the same value to eliminate fraction denominators
36=8x/7 so you multiply 7 times 36=7 times 8x/7
so you simplify so you get 252=8x
then you Divide both sides of the equation by the same term
252=8x 252/8=8x/8 so you get 63/2
so your final answer is x=63/2

Answer:
Try adding the percent of 5.
Step-by-step explanation:
(5 percent off 19.00 is 18.05 The difference is 0.95)
It might be ADDING in the situation
cause 19.00 + (5percent) = 19.95
Why: I think its adding a percent of 5
Because clue content.. And the clue was (total cost with service fee)
(total) is one of the context clues for addition or adding.
and it adding service fee.
so it wants an addition of the total cost with service fee.

Answer:
the total amount collected is 2,665
Step-by-step explanation:
The computation of the total amount collected is shown below:
= price × number of tickets sold × price + number of tickets sold × price + price
= 14 × 15 × 10 + 56 × 10 + 5
= 2,100 + 560 + 5
= 2,665
Hence, the total amount collected is 2,665

Petrov ran 7 laps around a track.Each lap around the track is a distance of 1/4 mile. What is the total distance Petrov ran in feet?
Answer:
9240 feet
Step-by-step explanation:
Petrov ran 7 laps around a track.Each lap around the track is a distance of 1/4 mile.
Step 1
The total distance Petrov ran in miles is calculated as:
1 lap = 1/4 mile
7 laps = x mile
Cross Multiply
x = 7 × 1/4 mile
x = 1.75 miles
Step 2
What is the total distance Petrov ran in feet?
1 mile = 5280 feet
1.75 miles = x
Cross Multiply
x = 1.75 × 5280 feet
x = 9240 feet
Therefore, the total distance Petrov ran in feet is 9240 feet

Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .

Ron works 8 hours a day, 5 days a week, $15 dollars an hour, for 12 weeks.
What is his gross pay?
Answer:
If Ron works 8 hours a day and get's paid $15 an hour
for 5 days a week and works for 12 weeks
1 hour = $15
8 hours = $120
So Ron get's paid $120 a day
So if he works 5 days a week then
120 x 5 = $600
Ron get's paid $600 a week
So if Ron works for 12 weeks then
600 x 12 = $7,200
Ron's gross pay is $7,200

The temperature was -2°F in the afternoon and is now -30°F. How many degrees did it drop?
Answer:
28°
Step-by-step explanation:
Let's take 'x' as the number of how much degrees it dropped. So this is how the equation will look like:
-2 - x = -30
It is '-x' since the temperature 'decreased', so you must a subtract.
Take -30 to the other side and substitute it with '-x'. Since both the terms are shifted, -30 will be +30 and -x will be +x (which is equivalent to x).
x = -2 + 30
x = 28°
∴ There was a 28° drop.

What is the perimeter of the triangle?
Answer:
The answer is 36
Step-by-step explanation:
First, suppose that each square is the unit length, and from it the length of the hall can be calculated and we find that it is equal to 10, then to find the value of the other two we drop a column of the vertex of the triangle on the base and find that its length is 12 units and it divides the base into two equal halves, so we determine that each side equals 13 units using Pythagoras and it will be The lengths of the sides of the triangle are 10, 13, 13
Then the perimeter is
[tex]10 + 13 + 13 = 36[/tex]
1. The amount paid for different weights of oranges at a farmer’s market are shown below. Oranges (lb) Price ($) 2 3 3 4.50 5 7.50 ? 12 (a) Is the relationship between the price and the weight of the oranges proportional? Use the first three rows of data to answer this question. Show your work and explain. How many pounds of oranges cost $12? Show your work.
due today.
Answer:
Relationship is proportional ;
8 oranges
Step-by-step explanation:
Oranges (lb) 2 ___ 3 ____5 ___?
Price ($) __ 3 ___4.50___7.50_12
For proportionality :
Oranges = k * price
Where, k = constant of proportionality
2 = 3k
k = 2 /3
k = 0.666666
Using k :
Number of oranges at price = 4.50 should be:
0.66666 * 4.50 = 3
Number of oranges at price = 7.50 should be:
0.66666 * 7.50 = 5
Hence, relationship is proportional
Number of oranges at $12
0.66666 * 12 = 8
