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
Which triangle is similar to /\JKL
A. /\JKM
B. /\MKL
C. /\KML
D. /\LJK
Answer:
ΔKML Option C
Step-by-step explanation:
Given right triangle is ΔJKL
Where ∠JKL = 90°
Here KM is perpendicular to LJ.
In triangle ΔJKL & ΔKML
∠JKL ≅ ∠KML (both are right angle)
∠JLK ≅ ∠KLM (common angle in both the triangles)
So,
ΔJKL is similar to ΔKML.
That's the final answer.

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?
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?
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.

John bikes 22km per hour and starts at mile 10. Gwynn bikes 28 km per hour and starts at mile 0. Which system of linear equations represents this situation?
Answer:
[tex]d=22t+10...(1)[/tex]
[tex]d=28t...(2)[/tex]
Step-by-step explanation:
Let t represent the number of hours and d represent the total distance after t hours.
We have been given that John bikes 22 km per hour and starts at mile 10. This means that slope of line will be 22 and y-intercept will be 10. So total distance covered by John in t hours will be:
[tex]d=22t+10...(1)[/tex]
We are also told that Gwynn bikes 28 km per hour and starts at mile 0. This means that slope of line will be 28 and y-intercept will be 0. So total distance covered by Gwynn in t hours will be:
[tex]d=28t+0[/tex]
[tex]d=28t...(2)[/tex]
Therefore, our required system of linear equations will be:
[tex]d=22t+10...(1)[/tex]
[tex]d=28t...(2)[/tex]

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]

A tile factory earns money by a flat fee for delivery and sales price per tile sold. For one customer the tile factory shipped 10,000 units of retail stores at the rate of $0.25 Per tile. The total tile factory earned from that sale was 3000 which of the following equation describes the revenue of the tile from this sale in terms of tiles
Sold?
A) y=0.25x+10,000
B) y=0.25x+3,000
C) y=0.25x+500
D) y=0.25x+0.25
10,000 tiles * 0.25 = 2500
3000 -2500 = 500
so the delivery fee is 500 and the tiles cost 0.25 each
so the equation would be y = 0.25x +500
Answer is C
Solve the equation.

There are 6,657 marbles in a jar. approximately 34% are white, and the rest are black. how many black marbles are there?
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.

What is the value of k?
2k+9=7−3k
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.
