A store charges $414 for a small refrigerator, the price consists of the refrigerator's original cost to the store plus a profit 15% what was the refrigerator's original cost to the store?
Step one:
given data
we are told that the price of the small refrigerator contains both the original price and 15% profit
mathematically
$414= original price + 15% profit
Step two:
let us solve for 15% of 414
=(15/100)*414
=0.15*414
=$62.1
This shows that the profit is $62.1
let the original price be x
$414= x + 62.1
solve for x
x=414-62.1
x=351.9
The refrigerator's original cost to the store $351.9
A linear function has the same y-intercept as x + 4y = 8 and its graph contains the point (5,3). Find the slope of the linear function. Write the slope in fraction form.
Answer:
x - 5y = - 10
Step-by-step explanation:
y = mx + b (b is y-intercept)
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
~~~~~~~~~~~~
x + 4y = 8 ⇔ y = [tex]-\frac{1}{4}[/tex] x + 2 ⇒ y-intercept is 2 and coordinates of y-intercept are (0, 2)
(5, 3)
m = [tex]\frac{3-2}{5-0}[/tex] = [tex]\frac{1}{5}[/tex]
y = [tex]\frac{1}{5}[/tex] x + 2 (slope-intercept form)
x - 5y = - 10 (standard form)

Markups The depth of water in a pond increases by 3% after a heavy rain. If the average depth of the water was 8.3 feet, what is the new depth?
Answer: 8.55 feet
Step-by-step explanation:
We should equal the average depth to 1, so if it raises 3%, it raises 0.03. Simply add the original (1) plus what it rose (0.03) and multiply the original by that, so 8.3 × 1.03 = new depth. The result is 8.549 feets.

9. m and 2m are like terms, 3³ and 2 are like terms
10. 6³ and 6² are like terms, y³ and 5y³ are like terms
Step-by-step explanation:
The like terms are the terms that have the same variable with the same powerAll numerical rational terms are like termsThe numerical terms with the same radical are like termsLet us solve from No. 7 to No. 10
#7
∵ The terms are 2b, [tex]b^{6}[/tex], b, [tex]x^{4}[/tex], 3[tex]b^{6}[/tex], 2x²

∴ 2b and b are like terms
∵ [tex]b^{6}[/tex] and 3[tex]b^{6}[/tex] have same variable b and same power 6
∴ [tex]b^{6}[/tex] and 3[tex]b^{6}[/tex] are like terms
#8
∵ The terms are 6, 2n, 3n², 6m², [tex]\frac{n}{4}[/tex], 7
∵ 6 and 7 are numerical rational terms
∴ 6 and 7 are like terms
∵ 2n and [tex]\frac{n}{4}[/tex] have the same variable and the same power
∴ 2n and [tex]\frac{n}{4}[/tex] are like terms
#9
∵ The terms are 10k², m, 3³, [tex]\frac{p}{6}[/tex], 2m, 2
∵ m and 3m have the same variable and the same power
∴ m and 2m are like terms
∵ 3³ and 2 are numerical rational terms
∴ 3³ and 2 are like terms
#10
∵ The terms are 6³, y³, 3y², 6², y, 5y³
∵ 6³ and 6² are numerical rational terms
∴ 6³ and 6² are like terms
∵ y³ and 5y³ have the same variable and the same power
∴ y³ and 5y³ are like terms
Put the following equation of a line into slope-intercept form, simplifying all fractions. 3x+4y=-4
Answer:
Don't come at me if I'm wrong, but I think it's y=-3/4x-1 1/3
Step-by-step explanation:
1) you have to subtract 3x from both sides (this makes it 4y=-3x-4)
2) you then divide by 4 on both sides (it will become y=-3/4=4/3)
3) then you simplify the fractions (it becomes y=-3/4x-1 1/3)

Answer:
C y=2x-6
Step-by-step explanation:
the diffrence in each one is two by using two as slope you get -6 as y intercept.
Answer:
y = 2x - 6 (Third option)
Step-by-step explanation:
(-6, -18), (-1, -8)
m = (-8 - (-18)) / (-1 - (-6))
m = (-8 + 18) / (-1 + 6)
m = 10 / 5
m = 2
-8 = 2(-1) + b
-8 = -2 + b
b = -6
y = 2x - 6

Marshall is writing an equivalent equation to solve for x. What should be his next step? 5 x + 4 y = 8. 5 x + 4 y minus 4 y = 8 minus 4 y. 5 x = 8 minus 4 y.
Answer:
d)Divide both sides of the equation by 5.
Step-by-step explanation:
Marshall is writing an equivalent equation to solve for x. What should be his next step?
5x+4y=8
5x+4y-4y=8-4y
5x=8-4y
a)Add 5x to both sides of the equation.
b)Subtract 5x from both sides of the equation.
c)Multiply both sides of the equation by 5.
d)Divide both sides of the equation by 5.
5x + 4y = 8
Subtract 4y from both sides
5x + 4y - 4y = 8 - 4y
5x = 8- 4y
Divide both sides by 5
5x / 5 = (8 - 4y) / 5
x = (8 - 4y) / 5
Marshall's next step should be to divide both sides of the equation by 5
Answer: D)Divide both sides of the equation by 5.

On Wednesday Mr. Miles walked in right at 9/10 of the trail then he walked one eights of the trail back and you stop to rest what fraction of the course with Mr. Miles from the beginning of the trail when he stopped
Answer:
31/40
Step-by-step explanation:
Given that:
Fraction of the trail walked intulally = 9/10
Fraction of the trail walked back = 1/8 before stopping to rest
His current distance from the beginning :
Distance walked initially - distance walked back
9/10 - 1/8
The L. C. M of 10 and 8 = 80
Hence,
9/10 - 1/8
= (72 - 10) / 80
= 62 / 80
= 31 / 40
Hence, his rest point or position is 31/40 from the beginning of the trail

Jason traveled 26 miles. The first 2 hours his speed was 4 mph, and the rest of the way his speed was 3mph. How long was he traveling?
Answer: 8 hours
Step-by-step explanation: You would first multiply 2 hours by 4 mph, and get 8 miles. You would then subtract 8 miles from 26 miles, and have 18 miles left. You would now divide 18 miles by 3, as he is now traveling 3 miles per hour and needs to travel 18 miles. You would get 6 hours. You would now add 6 hours by the 2 hours initially traveled at 4 mph, and get 8 hours.

4. A bottle contains 68 teaspoons of solution. The solution drops out of the bottle
at a constant rate during a 102-minute experiment. The bottle is completely empty
just as the experiment ends. At what rate does the number of teaspoons of
solution in the bottle change?
Answer:
The rate of solution change is 2/3 teaspoons per minute
Step-by-step explanation:
Here, we want to calculate rate
From what we have in the question,
68 teaspoons of solution dropped out entirely within 102 minutes
So the rate is takes to drop out per minute will be:
68/102 = 2/3 teaspoon per minute

In the equation, y = 8.5x the variable y represents time and x represents the distance in miles.
What is a linear equation?The linear equation is defined as the equation having a degree of one or the power of the variable will be one. It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that John ran 3 miles in 25.5 min the equation y = 8.5x. The equation is satisfying the answers. The solution will be calculated as follows:-
y = 8.5x
Here, the y variable is the total time and x is the distance in miles.
y = 8.5x
For 3 miles the time will be calculated as follows:-
y = 8.5 x 3
y = 25.5 minutes
Therefore, in the equation, y = 8.5x the variable y represents time and x represents the distance in miles.

Where will the lines y= -2/5x + 1 and y= -2/5x - 2 intersect?
Answer:
Never
Step-by-step explanation:
Their slope is the same so they will go down the same distance every time, and since the first one touches the y-intercept at 1 and the other one touches the y-intercept at -2, it is completely impossible for them to ever intersect

Last year's computer models were priced at $1,850. They are now discounted 20%. What is the new retail price to the nearest dollar of that computer? $370 $1,480 $1,510 $1,830
Answer:
$1480Step-by-step explanation:
Step one:
Given that the price last year was $1850
and now the discount is 20%
we first need to solve for 20% of $1850
=20/100*$1850
=0.2*$1850
=$370
This means that the price was reduced by $370
so the new retail price is calculated as
=$1850-$370
=$1480

For a segment of a radio show a disc jockey can play 8 records. If there are 10 records to select from, in how many ways can the program for thid segment be arragned
Answer:
45 ways
Step-by-step explanation:
Combination method is appropriate for this question since it deals with arrangement.
i.e [tex]^{n}C_{r}[/tex] = [tex]\frac{n!}{(n - r)!r!}[/tex]
Since 8 records are to be selected from 10 available records. Then, the number of ways for the arrangement of the records can be determined as;
Let n = 10 and r = 8
[tex]^{10}C_{8} }[/tex] = [tex]\frac{10!}{(10 - 8)!8!}[/tex]
= [tex]\frac{10!}{2!8!}[/tex]
= [tex]\frac{10*9*8*7*6*5*4*3*2!}{2!8*7*6*5*4*3*2!}[/tex]
= [tex]\frac{10*9}{2}[/tex]
= 45
Therefore, the number of ways by which the records can be arranged is 45.
