190 is the answer of the equation.
Step-by-step explanation:
a(b + c) × 2
Now putting the values of a,b and c.
5(7+12)×2
= 5(19)×2
= 95×2
= 190
A line passes through the points (0, –5) and (8, –10). What is its equation in slope-intercept form?
Answer:
y=-[tex]\frac{5}{8}[/tex]x-5
Step-by-step explanation:
Start with the slope equation [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex].
[tex]\frac{-10-(-5)}{8-0}=\frac{-5}{8}[/tex]
This is the slope of your equation
Now rearrange the slope-intercept equation to get your y-intercept
y=mx+b
y-mx=b
Now substitute either of your two points to find your y-intercept
-10-(-[tex]\frac{5}{8}[/tex](8))=b
-10-(-5)=b
-10+5=b
b=-5
Now that you have slope and the y-intercept you can write your equation:
y=-[tex]\frac{5}{8}[/tex]x-5
what is 4-1/4 help please
Answer:
It lets me add one now! The answer is 3.75
Step-by-step explanation:
1/4 of a unit is 25%
When converted to a decimal, 25% = .25
4 - .25 = 3.75
We can check this by using reversive property:
4 - .25 = 3.75
3.75 + .25 = 4
Mr. Webster is buying carpet for an exercise room in his basement. The room will have an area of 230 square feet. The width of the room with have 12&1/2 feet. What is the length?
PLEASE DO NOT JUST GIVE THE ANSWER, (I could have done that myself) PLEASE SHOW WORK ON HOW YOU GOT THE ANSWER.
Thanks!
Answer: 18.4 ft
Step-by-step explanation:
Area= L x W
230= 12.5 x L (Divide both sides by 12.5 to get L)
L= 18.4 ft
Answer:
The length of the room is 18 2/5 feet.
Step-by-step explanation:
The formula for finding the area of rectangles is A = l · w
Since the area and width is given to you, we can substitute that in the formula:
230 = l · 12 1/2
Now we convert the 12 1/2 to an improper fraction so it is easier to solve.
Here's how you convert a mixed number to an improper fraction:
12 · 2 = 24
24 + 1 = 25
and put 25 over the original denominator
= 25/2
Now you can add that to the equation...
l · 25/2 = 230 (I put 230 on the right side because that is how I am used to solving equations, but you can leave it on the right side as well. It is up to you)
To get rid of fractions, multiply by the reciprocal (Basically you flip the fraction so that the numerator becomes the denominator and the denominator becomes the numerator) on both sides
25/2 · 2/25 cancels itself out
and
230/1 · 2/25...
230 · 2 = 460
1 · 25 = 25
So you would get 460/25
Thus, we end up with:
l = 460/25
Divide 460 by 25 and you get 18.4...
Technically 18.4 is the answer but in decimal form.
If you want it in fraction form, just take 0.4 and put it over 10 because 0.4 is in the tenths place. 4/10 simplifies down to 2/5...
Therefore, the answer is 18 2/5 feet.
I hope this is helpful! Let me know if you have any further questions :D

A truck can be rented from Company A for $90 a day plus $0.20 per mile. Company B charges $30 a day plus $0.60 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answer: 150 miles
Step-by-step explanation:
Let A stand for Company A's Total Price, and B for Company B. Let x be the number of miles driven.
A = $90 + ($0.20/mile)*x
B = $30 + ($0.60/mile)*x
We want to know for what x does A = B
$90 + ($0.20/mile)*x = $30 + ($0.60/mile)*x
$60 + ($0.20/mile)*x - ($0.60/mile)*x = 0
$60 + x*($0.20/mile) - ($0.60/mile)) = 0
$60 + x*(- ($0.40/mile)) = 0
x*(- ($0.40/mile)) = -$60
x = -$60/(-$0.40/mile)
x = 150 miles
Company A, 1 day, 150 miles = $120
Company B, 1 day, 150 miles = $120
At 150 miles, and just 1 day, both companies will charge a total of $120 for the rental.

A large pool has a faucet to allow water to enter the pool and a drain to allow water to leave the pool.
Each minute, the faucet allows 10 3/4 gallons of water to enter the pool, and the drain allows 12 1/3 gallons to leave the pool.
What is the change in the amount of water in the pool after 112 minutes?
Enter your answer as a simplified mixed number by filling in the boxes.
The change in the amount of water in the pool is the difference between the amount of water that enters and leaves the pool
Change in volume of water in the pool after 112 minutes is [tex]\underline{-117\frac{1}{3}}[/tex] gallons
Reason:
The given parameters are;
The volume volume of entering the pool = 10 3/4 gallons per minute
The volume of water leaving the pool = 12 1/3 gallons per minute
Required:
The change in the amount of water in the pool after 112 minute
Solution:
The volume of water, V₁, that enters the pool in 112 minute is given as follows;
V₁ = 10 3/4 × 112 = 1,204The volume of water, that enters the pool, V₁ = 1,204 gallons
The volume of water, V₂, that leaves the pool in 112 minute is given as follows;
V₂ = 12 1/3 × 112 = 1,381[tex].\overline 3[/tex]The volume of water, that that leaves the pool, V₂ = 1,381[tex].\overline 3[/tex] gallons
The change in the amount of water in the pool after 112 minutes, ΔV, is given as follows;
ΔV = V₁ - V₂
ΔV = 1,204 - 1,381[tex].\overline 3[/tex] = -177[tex].\overline 3[/tex] = -(117 1/3)Change in volume of water in the pool after 112 minutes, ΔV = [tex]\underline{-117\frac{1}{3}}[/tex] gallons

3x - 2y = 8
2x + 2y = -8
Answer:
(0, - 4 )
Step-by-step explanation:
3x - 2y = 8 → (1)
2x + 2y = - 8 → (2)
Adding (1) and (2) term by term will eliminate the y- term
5x + 0 = 0
5x = 0 , then
x = 0
Substitute x = 0 into either of the 2 equations and solve for y
Substituting into (2)
2(0) + 2y = - 8
0 + 2y = - 8
2y = - 8 ( divide both sides by 2 )
y = - 4
solution is (0, - 4 )

use the model to solve for X.
Answer:
X=3
Step-by-step explanation:
First you subtract 3x from both sides to keep x on one side.
5x minus 3x is 2x.
Then you subtract 1 from both sides to keep the variable alone.
7 minus 1 is 6.
Then you divided both sides by 2.
2x divided by 2 is x and 6 divided by 2 is three.
Then all you have left is x=3

Watching a Helicopter Take Off At a distance of 58 ft from the pad, a man observes a helicopter taking off from a heliport. If the helicopter lifts off vertically and is rising at a speed of 55 ft/sec when it is at an altitude of 113 ft, how fast is the distance between the helicopter and the man changing at that instant? (Round your answer to one decimal place.)
The Pythagora´s Theorem, tell us that in a right triangle, the square of the hypothenuse (L²) is equal to :
L² = x² + y²
x and y are the legs.
The solution is
dy/dt = 48.9 ft/s
We know that in a right triangle:
L² = x² + y² (1)
If the helicopter lifts off vertically, that means x ( the horizontal distance between the observing man and the helicopter, maintains constant).
According to that, if we get derivatives with respect to time on both sides of equation (1) we get:
2×L× dL/dt = 0 + 2×y×dy/dt (2)
And
L = √ ( 58)² + ( 113)² = √12769 + 3364 = 127.02 ft
L = 127.02 ft when y = 113 ft
Now in equation (2) we know:
y = 113 ft dy/dt = 55 ft/s L = 127.02 we look for dL/dt
Then by substitution
2×127.02 × dL/dt = 2×113×55
254.04× dL/dt = 12430
dL/dt = 48.92
dL/dt = 48.9 ft/s

Airfare from Atlanta, GA to Nashville,TN was decreased from $250 to $180. By what percentage did the cost of the airfare change?
Answer:A decrease of 28%
Step-by-step explanation: the question says decreased so you can mark out A and B then 250-180 is 70, 70% of 250 is 28%
The percentage is the indicating hundredth thus the percentage change from $250 to $180 is 28%.
What is the percentage?
The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
As per the given question,
Initial price of Airfare = $250
Final price of Airfare = $180
The percentage = change/initial × 100
Percentage decrease = (250 - 180)/250 × 100
⇒ 0.28 × 100 = 28%
Hence "The percentage is the indicating hundredth thus the percentage change from $250 to $180 is 28%".
