Answer:

45 cookies

Step-by-step explanation:

Use a unit rate.

With a unit rate, we find the number of cookies that are baked using 1 scoop.

(30 cookies)/(6 scoops) = 5 cookies/scoop

The rate of 30 cookies to 6 scoops is the same as the unit rate of 5 cookies/scoop.

Now we multiply the unit rate by 9 scoops.

9 scoops * 5 cookies/scoop = 45 cookies

Answer: 45 cookies

Lelu [443]

Answer:

840 cubic inches

Step-by-step explanation:

Given:

The wooden steps have two parts.

Both of which are rectangular prisms.

The top part is 6 inches tall, 5 inches wide and 10 inches long.

The bottom part is 6 inches tall, 9 inches wide and 10 inches long.

Question asked:

What is the volume of the steps?

Solution:

For top part

Length = 10 inches

Width = 5 inches

Height = 6 inches

As we know:

$Volume\ of\ rectangular\ prism =length\times width\times height$

$=10\times5\times6=300\ cubic\ inches$

For bottom part

Length = 10 inches

Width = 9 inches

Height = 6 inches

Similarly

$Volume\ of\ rectangular\ prism =length\times width\times height$

$=10\times9\times6=540\ cubic\ inches$

Volume of two steps = 300 + 540 = 840 cubic inches

Therefore, the volume of the steps are 840 cubic inches.

A large university accepts 60% of the students who apply. Of the students the university accepts, 50% actually enroll. If 10,

prisoha [69]

we need to find 1% of 10000 first

so we divide 10000:100= 100 (that's 1%)

to find the 60% which will be accepted we multiply 100 × 60 = 6000 students accepted

of those 6000 we need to find 50% which is ½ so we basically just divide by 2, aka 6000 : 2 = 3000 people which will be enrolled
