A car and a truck left Washington, DC traveling in opposite directions. The car
traveled 19 miles
per hour faster than the truck, and at the end of 8 hours they were
1048 miles apart. What was the average speed of each vehicle?
Answers
Answer:
The speed of the car is 75 mph.
The speed of the truck is 56 mph.
Step-by-step explanation:
Call the speed of the truck (x) miles per hour. As per the given information, the car is (19) miles per hour faster. Thus, one can form expressions to represent the speeds of the vehicles.
car = ( x + 19 ) mph
truck = ( x ) mph
Using the formula, ( (speed) * (time) = (distance) ), one can say that the speed of the car, times the time it took plus the speed of the truck times the time will equal the distance between the two vehicles:
(( car speed )( time )) + (( truck speed )( time )) = ( distance between vehicles )
Substitute,
( ( x + 19 ) ( 8 ) ) + ( ( x ) ( 8 ) ) = 1048
Simplify,
8x + 152 + 8x = 1048
16x + 152 = 1048
-152 -152
16x = 896
/16 /16
x = 56
Add (19) to find the speed of the car:
truck speed + 19
= 56 + 19
= 75
The speed of the car is 75 mph.
The speed of the truck is 56 mph.
Answer:
The truck traveled at 81
mph. The car traveled at 100
mph.
Step-by-step explanation:
A patrol officer used radar to note the speeds of cars, in miles per hour, as
they went by on the highway
65, 66, 63, 56, 56 50, 85, 61, 73, 81
How fast will the next car need to be going to change the median speed of
the cars to 63 miles per hour?
A. 80 miles per hour
B. 75 miles per hour
C 65 miles per hour
D 61 miles per hour
Answers
Answer: 61 miles per hour.
Step-by-step explanation:
The median is the number that's placed in the middle when the given numbers are either arranged in the ascending it the descending order.
In this case we are already given the speed of the cars as 65, 66, 63, 56, 56 50, 85, 61, 73, 81. We will therefore arrange them in ascending order and this will be:
50, 56, 56, 61, 63, 65, 66, 73, 81, 85.
To change the median speed of
the cars to 63 miles per hour, the 6th number when arranged in ascending order has to be 63. Therefore, in thus case, we will need a speed lessee than 63 miles pee hour. Therefore, option D is the answer.
When we re-arrange with the new speed included. This will be:
50, 56, 56, 61, 63, 63, 65, 66, 73, 81, 85.
Therefore, we can see that the median is 63.

skateboarding ramp is 12in. high and rises at an angle of 23 degrees. How long is the base of the ramp? Round to the nearest inch.
Answers
Answer:
the length of the base of the ramp is 28.27 inches
Step-by-step explanation:
The computation of the length of the base of the ramp is shown below:
Let us assume x be the length of the base of the ramp
Now the following formula should be used
tan = opposite ÷ adjacent
tan 23 degrees = 12 ÷ x
x = 12 ÷ tan 23 degrees
= 12 ÷ 0.42447482
=28.27 inches long
Hence, the length of the base of the ramp is 28.27 inches

Write an equation that represents the total cost for pop music bundles. Write another equations to represent the total cost for rock music bundles. Identify the variables in the equations.
Answers
Answer:
Equation for the total cost for pop music bundles = $ 1200 x + 300
Where variable is the Cost.
Equation for the total cost for rock music bundles = $ 950 x + 250
Where variable is the Cost.
Step-by-step explanation:
P.S - The exact question is -
Given - The Music Express is going to buy music bundles from a
company that is going out of business. The company
charges different amounts for bundles of pop and rock
music:
Cost for each pop music bundle is $1200
Cost for each rock music bundle is $950
One - time fee for rights to the pop music is $300
One - time fee for rights to the rock music is $250.
To find - Write an equation that represents the total cost for pop
music bundles.
Write another equations to represent the total cost for rock
music bundles.
Identify the variables in the equations.
Proof -
Given that,
Cost for each pop music bundle is $1200.
Cost for each rock music bundle is $950.
One - time fee for rights to the pop music is $300.
One - time fee for rights to the rock music is $250.
Let the total music bundles buy = x
Now,
Given, Cost for 1 pop music bundle = $1200
⇒Cost for x pop music bundles = $ 1200 x
Also given,
One - time fee for rights to the pop music is $300.
∴ we get
Equation for the total cost for pop music bundles = $ 1200 x + 300
Where variable is the Cost.
Now,
Given, Cost for 1 rock music bundle = $950
⇒Cost for x pop music bundles = $ 950 x
Also given,
One - time fee for rights to the pop music is $250.
∴ we get
Equation for the total cost for rock music bundles = $ 950 x + 250
Where variable is the Cost.

Daniela fue a la florería a comprar rosas rojas para regalar a su madre el día de su cumpleaños. Si una rosa cuesta $2.550 ¿Cuánto cuesta 2 docenas?
Answers
Answer:
2 docenas cuestan $61.200.
Step-by-step explanation:
Para encontrar la respuesta, debes considerar que una docena equivale a 12 artículos, por lo cual tienes que multiplicar 12 por 2 para encontrar el número de rosas en 2 docenas:
12*2=24
Ahora, dado que sabes que una rosa cuesta $2.550 tienes que multiplicar este valor por 24 para encontrar cuanto cuestan 2 docenas:
$2.550*24=$61.200
De acuerdo a esto, la respuesta es que 2 docenas cuestan $61.200.
