ROCKET SLED On a track at an Air Force base in New Mexico, a rocket sled
travels 3 miles in 6 seconds. What is the average speed in miles per hour?
Answers
Answer:
Answer: Rocket distance (rocket sled) =3 mil Time Taken=6seconds
Average Speed=Total Distance ÷ Time Taken. Average speed= 3÷ 6=1/2. So therefore average speed in miles per seconds= Average in miles/seconds
Average speed in miles per seconds=1/2
Average in miles/hour = Average speed in miles per seconds/hour.
Average in miles/hour=1/2÷60=30
Therefore Average speed in miles per hour =30 miles per hour

[tex]6x - 8 = 2x + 4 \\ 6x - 2x = 4 + 8 \\ 4x = 12 \\ x = 3[/tex]
Answer:
C.) x = 3
Step-by-step explanation:
The diagonals of a rectangle are equal, and QM and PM are both half of the two diagonals. You can now say that 2 * (6x - 8) = 2 * (2x + 4), meaning that 12x - 16 = 4x + 8, where you can add 16 on both sides, then subtract by 4x on both sides to get that 8x = 24. Now divide by 8 on both sides to get that x = 3.
Amela put 15x- 4 gallons of gas in her car at the beginning of the week. She used 7x-3 gallons driving to work. Which of the following choices represents the
number of gallons left in her car?
A) 22x+7
B) 22x-7
C) 8x+1
D) 8x-1
Answers
Answer:
D) 8x - 1
Step-by-step explanation:
Let's say that x = 5. That would mean Amelia put 15(5) - 4 gallons of gas in her car, which equals 71 gallons. She used 7(5) - 3 gallons driving to work, which is 32 gallons used. 71 - 32 = 39 gallons left.
What else equals 39, you might ask?

Berny bought a soft drink for 2 dollars
and 6 candy bars. He spent a total of
20 dollars. How much did each candy bar cost
bar cost?
Answers
Answer:
3
Step-by-step explanation:
Given:
Berny spent 20 dollars total
He spent 2 dollars on a soft drink
He bought 6 candy bars
Solution:
Amount spent on candy bars = total amount spent - amount spent on soft drink.
Amount spent on candy bars = 20 - 2 = 18
Cost of each candy bar = total amount spent on candy bars / # of candy bars bought
Cost of each candy bar = 18/6 = 3
Answer: Each candy bar costs $3
Step-by-step explanation:
Set variables
Soft drink = $2
Candy bars = $6x
Let x be the cost for each candy bar.Total cost = $20
Set equation
2 + 6x = 20
Subtract 2 on both sides
2 + 6x - 2 = 20 - 2
6x = 18
Divide 6 on both sides
6x / 6 = 18 / 6
x = 3

HELP ME PLS THIS NEEDS TO BE DONE TONIGHT AND TURNED IN TOMORROW The Hamiltons are paving their driveway. They are paving a rectangular area and an area in the shape of a parallelogram to make it easier to turn around and pull out of the driveway. A sketch of the plan for their driveway uses a scale of 1 in. for every 3 ft. What is the actual area of the entire driveway they want to pave?
Answers
Answer:
1350 ft²
Step-by-step explanation:
First off, I notice that the triangle at the bottom can fit the slant at the top to make a perfect rectangle.
This will leave us with a rectangle. We can add up 4 and 5 for the sum of 9, making one side 9 inches.
5 + 4 = 9 in
We multiply 9 by 3 to get the actual length of that side
9 x 3 = 27 ft.
We multiply 16 and two-thirds by 3 to get the actual length of the other side
[tex]16\frac{2}{3}[/tex] x 3 = 50 ft.
To find the area of this rectangle we multiply length and width
50 x 27 = 1350 ft²
Jaulas father throws Kayla a graduation party that costs $773. He pays the DJ $250, $75 for the cake, and $4 per party guest for food. How many guests were at the party?
Answers
Answer:
112 guests
Step-by-step explanation:
I. If her total cost is 773$
When Total = DJ + Cake + Guest
773 = 250 + 75 + 4(x)
773 = 325 + 4(x)
773 - 325 = 4(x)
448 = 4x
x = 448/4
x = 112
That makes guests are 112
