(30 POINTS + BRAINLIEST)A 102​-inch pipe is cut into two pieces. One piece is five times the length of the other. Find the length of the shorter piece!

Answers

Answer 1
Answer: The pipe is 17 inches long
Answer 2
Answer:

Answer:

shorter = 17 longer = 85

Step-by-step explanation:

x = longer y = shorter

102 = x + y              (whole pipe length, 102, = sum of the 2 pieces, x + y )

x = 5y                      (longer piece = 5 times length of shorter piece)

102 = 5y + y            (substitute for x)

102 = 6y                  (solve for y)

y = 17

102 = x + 17             (sub what you got for y back into original equation + solve)

x = 85

When he starts his shift, the water level shows 4 gallons, or 128 cups of water. As the shift progresses, he records the level of the water every 10 minutes. After 2 hours, he uses a regression calculator to compute an equation for the decrease in water. His equation is W –0.414t + 129.549, where t is the number of minutes and W is the level of water. According to the equation, after about how many minutes would the water level be less than or equal to 64 cups? 150 minutes 160 minutes 170 minutes 180 minutes

HELP NOW PLLLLLZZZZZ!A hybrid car can travel 40 miles per gallon. Approximately how many gallons of fuel will the car need to travel 20 km? [1 mile = 1.6 km]

A. 0.3

B. 0.8

C. 2.5

D. 3.2

Answers

Answer:

In 0.3 gallon of fuel, the car will travel 20 km.

A is the correct option.

Step-by-step explanation:

We have been given that in 1 gallon of fuel the car can travel 40 miles.

Now, 1 mile = 1.6 km.

Hence, in 1 gallon the car travel 40×1.6 = 64 km

Let the car will consume x gallons of fuel to travel 20 km.

Thus, we have the equation

(1)/(64)=(x)/(20)

ON solving for x

x=(20)/(64)\n\nx=0.3

Therefore, in 0.3 gallon of fuel, the car will travel 20 km.

A is the correct option.

Answer: The car would need 0.3 gallons of fuel to travel 20km.

Step-by-step explanation: 40mile x 1.6km = 64km

                                           1 gallon     1 mile    1 gallon

20km ÷ 64km = 0.3125

Kirk's grandparents are really enjoying their portable music players and have downloaded many more albums. Maude now has 225 albums, 135 of which are heavy metal. Claude now has 420 albums, 270 of which are heavy metal. Which of Kirk's grandparents has a higher probability of listening to heavy metal?

Answers

To find who has a higher probability, we need to find the percentage of each grandparent's music that is metal.

Maude:
135/225 = 0.6 = 60%

Claude:
270/420 = 0.64 = 64%

Assuming each album has the same number of tracks, Claude has a higher probability of listening to heavy metal.
