Answer 1

Answer:

Answer:

7/12 of an hour

Step-by-step explanation:

you add them, by finding the common denominator.

1/3=4/12

1/4=3/12

3/12+4/12=7/12

Arrow is launched upward at 256 feet per second from top of 85 foot building. What is maximum height of arrow?

Answers

As arrow rises to its maximum height, its velocity decreases from 256 ft/s to 0 ft/s at the rate of 32 ft/s each second. Use the following equation to determine the distance it rises.

vf^2 = vi^2 + 2 * a * d, vf = 0, a = -32
0 = 256^2 + 2 * -32 * d
64 * d = 65,536
d = 65,536 ÷ 64 = 1024 ft
Maximum height = 85 + 1024 = 1109 ft

The arrow's maximum height above the ground can be calculated using maximum height. The maximum height reached from the launch point is 1024 feet. Adding the height of the building, the overall maximum height of the arrow is 1,109 feet.

To find the maximum height of the arrow, you can use the following formula:

Maximum Height = Initial Height + (InitialVelocity^2 / (2 * Acceleration due to gravity))

In this case:

Initial Height = 85 feet

Initial Velocity = 256 feet per second

Acceleration due to gravity (approximated as 32 feet per second squared)

Maximum Height = 85 + (256^2 / (2 * 32))

Maximum Height = 85 + (65536 / 64)

Maximum Height = 85 + 1024

Maximum Height = 1109 feet

So, the maximum height the arrow reaches above the ground is 1,109 feet.

Answer:

$w \leq \: 26$

Step-by-step explanation:

$(9w - 4)/(5) \leq (7w + 2)/(4)$

First of all cross multiply

That's

$4(9w - 4) \leq5(7w + 2)$

Expand the terms

$36w - 16 \leq \: 35w + 10$

Add 16 to both sides

That's

$36w + 16 - 16 \leq \: 35w + 10 + 16 \n 36w \leq35w + 26$

Subtract 35w from both sides

We have

$36w - 35w \leq35w - 35w + 26 \n$

We have the final answer as

$w \leq \: 26$

Instead of having a cake, Ruben wants to make ice cream sundaes at his next birthday party.He thinks each person will eat 2 cups of ice cream, and there will be 24 people at his party.
How many 1-gallon tubs of ice cream should he buy?
tubs

Answers

Final answer:

Ruben should buy 3 tubs of ice cream for his party.

Explanation:

To find the number of 1-gallon tubs of ice cream Ruben should buy, we need to determine the total amount of ice cream needed and then divide by the capacity of each tub. Since each person will eat 2 cups of ice cream and there will be 24 people at the party, the total amount of ice cream needed is 2 cups/person x 24 people = 48 cups. To convert cups to gallons, we divide by the number of cups in a gallon, which is 16. So, 48 cups ÷ 16 cups/gallon = 3 gallons. Therefore, Ruben should buy 3 tubs of ice cream for his party.
