Answer:

441

Step-by-step explanation:

Use a proportion.

756 miles is to 12 hours as x miles is to 7 hours

756/12 = x/7

12x = 7 * 756

12x = 5292

x = 441

Answer: 441 miles

Answer:

441

Step-by-step explanation:

756 divided by 12 = 63

Jim drives 63 miles in 1 hour

Multiply 63 by 7

63 ⋅ 7 = 441

Jim will drive 441 miles in 7 hours

The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing

tester [92]

The length of pendulum is 2.485 feet

<h3><u><em>Solution:</em></u></h3>

Given that,

The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing back and forth

<u><em>Therefore, the given formula is:</em></u>

$T=2\pi \sqrt{\frac{L}{32} }$

We have to find the length of pendulum that makes one full swing in 1.75 seconds

So the modify the given equation to find "L"

$T=2\pi \sqrt{\frac{L}{32} }\\\\ \sqrt{\frac{L}{32} }=\frac{T}{2 \pi}\\\\\text{Taking square root on both sides }\\\\\frac{L}{32} = \frac{T^2}{4 \pi^2}\\\\L = \frac{T^2}{4 \pi^2} \times 32\\\\L = \frac{T^2}{\pi^2 } \times 8$

Substitute T = 1.75 seconds and $\pi = 3.14$

$L = \frac{1.75^2}{3.14 \times 3.14} \times 8\\\\L = \frac{3.0625}{9.8596} \times 8\\\\L = 2.485$

Thus length of pendulum is 2.485 feet approximately

steposvetlana [31]

Answer:

Below.

Step-by-step explanation:

The dimensions will be 10 * 12.

(each new dimension will be 4 times the original)

The new perimeter will be 4 times the original.

The new area will be 16 times the original ( 4 * 4 = 16).

The new perimeter will be 44 cm.

I believe the answer is 28/40 which is reduced to 7/10.

It says large OR blue, so i added the total of large + blue, and its out of 40 total so i got 28/40. that reduces to 7/10.

sarah is putting her sweaters in boxes to organize her closet.seven sweaters can fit in each box. sarah will fill as many boxes

Morgarella [4.7K]

Given: Sarah can fit 7 sweaters in a box

She has 38 sweaters

the remaining sweaters will stack on the shelf in the closet.

By dividing 38 by 7 we will get:

$\frac{38}{7}=\frac{35+3}{7}=\frac{5\cdot7+3}{7}=5\frac{3}{7}$

So, she will need 5 boxes, she will put 35 sweaters in 5 boxes

The remaining sweaters = 38 - 35 = 3 sweaters

So, the answer is: 3 sweaters will go in her closet
