Answer: Percent of change is 70%.

Step-by-step explanation:

Since we have given that

$\frac{5}{4}\ to\ \frac{3}{8}$

We need to find the percent of change.

So, First we find the difference between them:

$\frac{5}{4}-\frac{3}{8}\\\\=\frac{10-3}{8}\\\\=\frac{7}{8}$

So, We know the formula for "Percent of change":

$\frac{Difference}{Original}\times 100\\\\=\frac{\frac{7}{8}}{\frac{5}{4}}\times 100\\\\=\frac{7\times 4}{8\times 5}\times 100\\\\=70\%$

Hence, Percent of change is 70%.

The red bus Company Charges 150+72 per hour to rent a bus The blue bus company charges 240+54 per hour for what number of hours

liraira [26]

It will take them 5 Hours to charge the same. The rental charge will be 510.

I did a manual computation per company: My computation is entirely based on trial and error.

Red Bus Co. has a fixed rental rate of 150 and additional rental of 72 per hour while Blue Bus Co. has a fixed rental rate of 240 and additional rental of 54 per hour. Both fixed rental rate are one time charges only and total rental will vary on the number of hours spent in using both vehicles.

Let's start with the Red Bus Co. I will be posting the charges per hour and its running balance. The running balance is the sum.

Fixed Rate 150 Running Balance: 150 => 150 + 0
Hr 1 72 222 => 150 + 72
Hr 2 72 294 => 222 + 72
Hr 3 72 366 => 294 + 72
Hr 4 72 438 => 366 + 72
Hr 5 72 510 => 438 + 72

I'll do the same process with Blue Bus Co.

Fixed Rate 240 Running Balanc: 240 => 240 + 0
Hr 1 54 294 => 240 + 54
Hr 2 54 348 => 294 + 54
Hr 3 54 402 => 348 + 54
Hr 4 54 456 => 402 + 54
Hr 5 54 510 => 456 + 54

Anika [276]

Answer:

The length of new ramp is 49.03 ft.

Step-by-step explanation:

It is given that 26 ft long ramp is used to reach 10 ft up a wall. The ramp covers a horizontal distance of 24 ft.

If the horizontal distance is doubled, then the horizontal distance is 48 ft. The height remains same. Therefore the height of ram is 10 ft.
