Answer:
Speed of car B is 33 km/h and speed of car A is [tex]45\,\,km/h[/tex]
Step-by-step explanation:
Let speed of car B be [tex]x[/tex] km/h
Speed of car A is 12 km/h more than car B.
Therefore,
Speed of car A = [tex](12+x)[/tex] km/h
Distance = Speed × Time
Distance travelled by car A in 4 hours = [tex]4(12+x)[/tex] km = [tex](48+4x)[/tex] km
Distance travelled by car B in 4 hours = [tex]4x[/tex] km
Also, cars A and B are 312km apart after 4 hours.
[tex]48+4x+4x=312\\48+8x=312\\8x=264\\\\x=\frac{264}{8}\\\\x=33\,\,km/h[/tex]
Speed of car B is 33 km/h and speed of car A is [tex]12+x=12+33=45\,\,km/h[/tex]

Jeremy has hit 5 home runs so
far this season. This represents
20% of his yearly goal. How many
more homeruns does he need to hit
to achieve his goal?
Answer:
20 home runs left to hit.
Step-by-step explanation:
Ok so 100%/20% is 5. Increment 5 home runs until you get to 100%. So, 20% =5, 40% = 10, 80% = 15, and 100% = 20
Answer: 25 home runs
Step-by-step explanation:
20% = 5
40% = 10
80% = 20
80% + 20% = 100%
5+10=25
The aspect ratio, the ratio of the width to the height, of various computer monitors is listed in the table below.
Answer: Monitor C is the different one.
Step-by-step explanation:
The aspect ratio is the relationship between width and height.
So we only need to see the quotients between width and height for each monitor and see which quotient is different.
Monitor A:
Quotient = 1152/864 = 1.333....
Monitor B:
Quotient = 800/600 = 1.333...
Monitor C:
Quotient = 1920/1080 = 1.777...
Monitor D:
Quotient = 1600/1200 = 1.333...
We can see that the one with a different aspect ratio is monitor C.

[tex]\frac{7^{12} * 7^{9}}{(7^{6})^{3} }[/tex] is the equation.
1. You can add the two exponents in the numerator --> [tex]7^{21}[/tex]
2. You can multiply the exponents in the denominator --> [tex]7^{18}[/tex]
(the equation is now [tex]\frac{7^{21} }{7^{18} }[/tex])
3. Subtract the exponents to get [tex]7^{3}[/tex]
[tex]7^{3}[/tex] = 343

Find x
16 ft
х
12 ft
Answer:
x = 20
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )
x = [tex]\sqrt{400}[/tex] = 20

[tex]\frac{1}{6}[/tex] + [tex]\frac{1}{4}[/tex] = finding common denominator which is 12. so multiply both sides with what makes them 12 ...... [tex]\frac{1}{6}[/tex] [tex]\frac{2}{2}[/tex] & [tex]\frac{1}{4}[/tex][tex]\frac{3}{3}[/tex] then add = [tex]\frac{5}{12}[/tex]
Joe would like to paint a rectangular shaped wall. The measures of dimensions of the wall are 8 inches by 4 inches. Every 1 inch represents 3 feet of the actual wall. If the cost of the painting is $2.50 per square feet, find the total cost of paint needed for the entire wall.
Answer:
$90
Step-by-step explanation:
8 + 4 = 12
12 x 3 (3 feet for each inch) = 36
36 x 2.50 (cost per square foot) = $90
Answer:
$240
Step-by-step explanation:
8 x 4 is 32
32 x 3 is 96
96 x 2.5 is 240
Carl rented a bounce house for his little brother's birthday party. The company charges a base rental charge of $95.25, plus a certain amount per hour. Carl's little brother's party lasted 4 hours, and costs $179.72. Carl plans to rent a bounce house for his little sister's birthday party for 6 hours for about $200. Is this a reasonable estimate? A. Yes, the estimate is reasonable. B. No, the estimate should be lower. C. No, the estimate should be higher.
Answer:
C. No, the estimate should be higher.
Step-by-step explanation:
Carl's brother party
Fixed charge = $95.25
Number of hours = 4 hours
Hourly charge = x
Total cost = $179.72
179.72 = 95.25 + 4x
179.72 - 95.25 = 4x
84.47 = 4x
x = 84.47/4
x = 21.1175
Hourly charge = $21.1175
Carl's little sister party
Estimated total charge = $200
Number of hours = 6
Fixed charge = $95.25
Hourly charge = $21.1175
Total charges = 95.25 + 6(21.1175)
= 95.25 + 126.705
= 221.955
Total charges = $221.955
C. No, the estimate should be higher

One of the legs of a right triangle measures 9 cm and the other leg
measures 4 cm. Find the measure of the hypotenuse. If necessary,
round to the nearest tenth.
Answer:
9.8cm
Step-by-step explanation:
The pythagorean theorem states that, for right triangles, [tex]a^{2}+b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.
a = 9cm
b = 4cm
c = hypotenuse
9^2 + 4^2 =c^2
81 + 16 = c^2
[tex]\sqrt{97} =c[/tex]
9.8 = c

What was the total amount of water in the tank before it was drained
450 gallons
510 gallons
560 gallons
570 gallons
Total amount of water before it was drained will be 510 gallons.
What is rate?"It is a ratio in which the two terms being compared have different units."
For given question,
We have been given a table for the number of gallons of water left in the tank after being drained for two amounts of time.
First we find the rate at which the water was drained from the tank.
[tex]r=\frac{450-330}{30-10}\\\\ r=\frac{120}{20}\\\\ r=6~gallons~per~minutes[/tex]
Let the amount of water in the tank before it was drained = 'x' gallons
And the initial time = 0
Using the rate formula,
[tex]r=\frac{x-450}{10-0}\\\\ 6=\frac{x-450}{10}\\\\ 60=x-450\\\\x=450+60\\\\x=510~gallons[/tex]
Therefore, total amount of water before it was drained will be 510 gallons.

On January 29, 2019, Australian authorities confiscated 157.7 kilograms of heroin with an estimated street value of 77 million AUD (Australian dollars). The exchange rate at the time was 1 USD = 1.42 AUD. Based on this information, what was the value in U.S. Dollars per pound for the heroin? Round your answer to the nearest thousand dollars.
Answer: $343849
Step-by-step explanation:
Since the exchange rate at the time was 1 USD = 1.42 AUD, therefore we will convert 77 million AUD to dollars which will be:
= 77 million / 1.42
= $54.225 million
Therefore, the value in U.S. Dollars per pound for the heroin will be:
= $54.225 million / 157.7
= $343849 pee pound
