Five pounds of birdseed is used to fill 4 identical bird feeders.

enyata [817]

Answer:

a. We need 1/4 for each feeder

b. To fill each feeder we need 1.25 pounds

c. We need 60 ounces to fill three bird feeders

Step-by-step explanation:

Five pounds of birdseed is used to fill 4 identical bird feeders,

a. We divide all the birdseed in 4 feeders, so, we need 1/4 for each feeder.

b. If we use 5 pounds for the 4 feeders, so each feeders will take 1/4 of the 5 pounds

=1/4 x 5=1.25 pounds

c. To fill three bird feeders we have to multiply the amount of pounds by feeder by 3 feeders

=1.25 pounds x 3

= 3,75 pounds

If 16 ounces are a pound

so, 16 x 3.75 = 60 ounces

A new car costs $8000 at full price. With a sales tax of 5.75%, how much will the car cost in total?

ioda

Answer:

$8460

Step-by-step explanation:

So for this problem we will use the base price of $8000 and add the additional cost of the 5.75% to find the total cost for the car.

So, to find the 5.75%, we simply multiply 8000 by .0575 to get 460.

So 8000 + 460 = 8460.

Thus, the total price of the car would be $8460.

Cheers.

The cheetah is 7/6 the Perigen falcon is 10/3

The answer is $2 \frac{1}{6}$ .

Explanation:

In order to subtract the fractions, we must make them like fractions. To do this, the denominators must be the same by multiplying (only). Since the first fraction is $\frac{10}{3}$ , 3 can be multiplied by 2 to get 6, which is the other fraction, we can multiply it. Whatever you do to the denominator you must do to the numerator. Now multiply 2 by the numerator (10) to get $\frac{20}{6}$ . Now we can subtract the fractions $\frac{20}{6}$ and $\frac{7}{6}$ to get 13/6. Since this fraction is not in mixed fraction form yet, we must do that first. goes into 13 twice, so the whole number is 2 and there is still 1 left, making the fraction $\frac{1}{6}$ . Therefore, the difference is 2 $\frac{1}{6}$ .
