Answers
To be 80% yellow, the new color will be (100%-80%=) 20% blue.
2 pints is 20% of (2 pints/0.20=) 10 pints.
With 4 pints in the bucket, to make 10 pints you should add
(10 pints-4 pints=) 6 more pints of yellow paint.

Find the average rate of change for f(x) = x2 + 9x + 18 from x = −8 to x = −2.
A)−1
B)−3
C)1
D)3
Answers
f(-8) = -8² +9(-8) + 18
f(-8) = 10
f(-2) = -2² + 9(-2) + 18
f(-2) =4 -18 +18
f(-2) = 4
f(-8) =10 and f(-2)=4
if a line was drawn between the two points (-8,10) and (-2,4) the slope (rise/run) would be -6/6, since the line would go down 6 units from 10 to 4, and over 6 units from x=-8 to x=-2.
The average rate of change, therefore, is -6/6, or

An Uber driver carries riders to and from a local airport and a neighboring suburb. Due to traffic and the time of day the driver works, the trip to the airport takes 60 minutes longer than the trip to the suburb. The car’s average speed in traffic is 30 miles per hour. Without traffic, the car travels 15 miles per hour. The equation can be used to determine how many miles apart the two locations are shown. What is the value of m, the distances between the two locations?
A) 0.5 miles
B) 22.5 miles
C) 30 miles
D) 90 miles
Answers
--------------------------------------------
--------------------------------------------
To find that answer, we simply solve for m
m/(30-15) = m/(30+15) + 1
m/15 = m/45 + 1
45*m/15 = 45*(m/45 + 1) ... multiply both sides by the LCD to clear out fractions
3m = 45*(m/45) + 45*(1)
3m = m+45
3m-m = m+45-m
2m = 45
2m/2 = 45/2
m = 45/2 <--- answer as a fraction
m = 22.5 <--- answer in decimal form

Seventy-five times an integer, minus 36, equals 21 times the square of the integer. Which equation could be used to solve for the unknown integer?
Answers
The equation: [tex]\( 21x^2 - 75x + 36 = 0 \)[/tex] represents "75 times an integer minus 36 equals 21 times the square of the integer."
To solve this problem, let's represent the unknown integer with the variable [tex]\( x \)[/tex]. Then we can set up the equation based on the given information.
The problem states: "Seventy-five times an integer, minus 36, equals 21 times the square of the integer."
Mathematically, this can be represented as:
[tex]\[ 75x - 36 = 21x^2 \][/tex]
So, the equation that could be used to solve for the unknown integer is:
[tex]\[ 21x^2 - 75x + 36 = 0 \][/tex]

Slope is 3, and (1,4) is on the line
Answers
3 is equal to 3/1, and you can use that to find the Y intercept. Start at the point that they game you and go up 3 and over 1. But this makes you further away from the Y axis, so you want to do the opposite. Go down 3 and over 1.\
This makes you end up on the Y intercept at (0,1)
Making the equation y=3x+1
Formular: y = mx + c
Where, m = slope
Given that m = 3,
Substitude 3 into m
y = 3x + c
Then add the coordinates (1, 4)
Where 1 being x and 4 being y
4 = 3(1) + c
Solve for C next
c = 1
Substitude m and c into the formular
y = 3x + 1

There are 6,657 marbles in a jar. approximately 34% are white, and the rest are black. how many black marbles are there?
Answers
If 100% = 1.00, then 66% = 0.66.
Now, you just need to multiply the total by this decimal in order to find the number of black marbles:
6657 x 0.66 = 4393.62, which can be rounded to 4394
Therefore, there are about 4394 black marbles in the jar.
I hope this helps!
To find the number of black marbles, calculate the percentage of white marbles first and then subtract it from the total marbles, there are 4,394 black marbles in the jar.
To find the number of black marbles:
Calculate the number of white marbles: 34% of 6,657 = 0.34 x 6,657 = 2,263.Subtract the number of white marbles from the total marbles to find the number of black marbles: 6,657 - 2,263 = 4,394.Therefore, there are 4,394 black marbles in the jar.

b. y+4=4(x-4)
c. y-4=4(x+4)

Answers
y - y1 = m(x-x1)
where,
m = slope
x1 = x coordinate of point the line goes through
y1 = y coordinate of point the line goes through
In this case,
m = 4
x1 = 4
y1 = -4
So,
y - y1 = m(x - x1)
y - y1 = 4(x - x1) ... replace m with 4
y - y1 = 4(x - 4) ... replace x1 with 4
y - (-4) = 4(x - 4) ... replace y1 with -4
y + 4 = 4(x - 4) ... rewrite y-(-4) as y+4

Answers
10,000 tiles * 0.25 = 2500
3000 -2500 = 500
so the delivery fee is 500 and the tiles cost 0.25 each

A service station checks Mr. Gittleboro's radiator and finds it contains only 30% antifreeze. If the radiator holds 10 quarts and is full, how much must be drained off and replaced with pure antifreeze in order to bring it up to a required 50% antifreeze?
Answers
Answer:
2.86 quarts ( approx )
Step-by-step explanation:
Given,
The initial quantity of the Mr. Gittleboro's radiator that contains 30% antifreeze = 10 quarts,
Let x quarts of pure antifreeze replaced x quarts of Mr. Gittleboro's radiator to bring it up to a required 50% antifreeze,
So, the quantity of 30% antifreeze radiator after drained off x quarts = (10-x) quarts
Also, the quantity of final antifreeze radiator 50% antifreeze = 10 quarts
Thus, we can write,
30% of (10-x) + 100% of x = 50% of 10
30(10-x) + 100x = 500
300 - 30x + 100x = 500
300 + 70x = 500
70x = 200
x = 2.85714285714 quarts ≈ 2.86 quarts
[tex]\boxed{{\mathbf{2}}{\mathbf{.86 quartz}}}[/tex] of [tex]30\%[/tex] antifreeze replaced by pure antifreeze to maintain [tex]50\%[/tex] antifreeze in the radiator.
Further explanation:
Given:
It is given that radiator contains [tex]30\%[/tex] antifreeze and the radiator holds 10 quartz.
Step by step explanation:
Step 1:
Consider [tex]x[/tex] as the number of quartz of pure antifreeze that is replaced by [tex]x[/tex] number of quartz of Mr. Gittleboro’s radiator to maintain the level of [tex]50\%[/tex] antifreeze in the radiator.
It is given that radiator contains [tex]30\%[/tex] antifreeze and the radiator holds 10 quartz.
The amount of [tex]30\%[/tex] antifreeze radiator after drained off [tex]x{\text{ quartz}}[/tex] is [tex]\left({10-x}\right){\text{quartz}}[/tex] .
The radiator only holds [tex]{\text{10 quartz}}[/tex] .
The amount of final antifreeze radiator [tex]50\%[/tex] antifreeze is [tex]{\text{10 quartz}}[/tex] .
Step 2:
The equation for maintain the level of [tex]50\%[/tex] antifreeze in the radiator by replacing the [tex]x[/tex] number of quartz of [tex]30\%[/tex] antifreeze by pure antifreeze as,
[tex]\begin{aligned}30\%{\text{ of}}\left({10-x}\right)+100\% {\text{ of }}x&=50\% {\text{ of 10}}\\\frac{{30}}{{100}}\times\left({10-x}\right)+\frac{{100}}{{100}}{\text{}}\times{\text{}}x&=\frac{{50{\text{ }}}}{{100}}\times{\text{10}}\\{\text{30}}\left({10-x}\right)+100x&=500\\\end{aligned}[/tex]
Now simplify the further equation using the distributive property.
[tex]\begin{aligned}{\text{30}}\left({10-x}\right)+100x&=500\\300-30x+100x&=500\\300+70x&=500\\70x&=500-300\\\end{aligned}[/tex]
Now simplify the further equation to obtain the value of [tex]x[/tex] .
[tex]\begin{aligned}70x&=500-300\hfill\\70x&=200\hfill\\x&=\frac{{200}}{{70}}\hfill\\x&=2.85714\approx 2.86{\text{ quartz}}\hfill\\\end{aligned}[/tex]
Therefore, [tex]2.86{\text{ quartz}}[/tex] of [tex]30\%[/tex] antifreeze replaced by pure antifreeze to maintain [tex]50\%[/tex] antifreeze in the radiator.

A fish swims at a speed of 12 miles per hour. A boy swims at a speed of 4.4 feet per second.
3 ft = 1 yd
5280 ft = 1 mi
How much faster does the fish swim than the boy in yards per minute?
Answers
The Boy: 4.4 x 60 = 264ft per minute. 264 / 3 = 88yrds Per minute
The Fish: 12 x 5280 = 63360ft hr. 5280 / 60 = 1056ft minute 1056 / 3 = 352yrds
352 - 88 = 44 yards quicker then the boy.
44 x 3 = 132 feet quicker then the boy.
21120 yards per hour.
Then you convert 4.4 feet per second into yards per second:
1.47 yards per second.
Then convert 1.47 yards per second into yards per hour:
5292 yards per hour.
Subtract 5292 from 21120:
15828 yards per hour.
Then convert that into minutes:
263.8 yards per minute.
The fish is 263.8 yards per minute faster than the boy.

What is the value of k?
2k+9=7−3k
Answers
To find the value of k in the equation 2k+9=7−3k, we rearrange and simplify to isolate k, resulting in k = -2/5.
To solve for the value of k in the equation 2k+9=7−3k, we must isolate the variable on one side of the equation. Let's start by adding 3k to both sides to get all the k terms on one side:
2k + 3k + 9 = 7 − 3k + 3k
5k + 9 = 7
Next, subtract 9 from both sides to get:
5k = 7 − 9
5k = −2
Now, to find the value of k, divide both sides by 5:
k = −2/5
Therefore, the value of k is −2/5.
