We can solve it two ways, we´ll do it via physics:
We know that:
d=vt
d=770km/h*15h
d=11550km
Now at 660km/h:
t=d/v
t=11550km/660km/h
t=17,5h
Math way:
770km/h→15h
660km/h→x
So:
(770*15)/660=x
x=17,5h

mario62 [17]

Answer:

c. 32 ounces

Step-by-step explanation:

Given that:

The weight of the Spot = 12 ounces

The weight of Rascal = 9.5 ounces;  &

The weight of Socks = 10.2 ounces.

To find the litters' total weight, we will sum all the given number of the puppies.

i.e. Total weight of the litter = (12 + 9.5 + 10.2) ounces

Total weight of the litter = 31.7 ounces

Total weight of the litter \simeq 32 ounces to the correct number of significant figures.

Westkost [7]

From previously received a monthly salary of $1,375.00, Your new monthly salary increase by six percent would be $1,457.50.

What is the percentage?

A percentage is a minimum number or ratio that is measured by a fraction of 100.

You previously received a monthly salary of $1,375.00

Now by economic expansion, causing wages to increase by 6%

Increment of the salary = 6% of 1,375.00

= 6/100 × 1,375

= 0.06 × 1,375

= $82.50

So, your new monthly salary would be = $1,375.00 + $82.50

                                                               = $1,457.50

Hence, your new monthly salary would be $1,457.50.
