4. Find the unit rate for 306 miles in 10 hours. (1 point)

Mathematics

viva [34]3 years ago

<span>4. Unit rate implies how much in one hour. If 306 miles is in 10 hours, in one hour, it will be just one-tenth of 306 miles. So divide 306 by 10. To divide by 10, just place a point before one digit from the right. So the answer will be 30.6 milers/hour. 5. Unit rate here implies how much in one month. If 33.6 gallons is in 6 months, in one month, it will be just one-sixth of 33.6 gallons. So divide 33.6 by 6. The answer will be 5.6 gallons/month.</span>

Out of the 25 students in Mrs. Coulter's class, 15 are girls. In the school there are 390 boys. If the ratio of boys to students
GREYUIT [131]

Answer:

975 students

Step-by-step explanation:

This is a dense question. Let's look at it piece by piece:

1. The ratio of boys to students in the class is 10/25. If there are 25 students and 15 girls, that leaves 10 boys.

2. The question says that the ratio is in proportion of boys to total students in the school. "In proportion" in this case means that if we convert 10/25 to a fraction with numerator 390, the denominator is the amount of students in school.

3. 10x39=390. What you do the numerator you must do to the denominator: 25x39=975.

4. This means 975 students go to the school.

Which expression can be used to find the surface area of the following square pyramid?
telo118 [61]

Answer:

Step-by-step explanation:

The slant height of one side of this pyramid is 5, and the base of this side is 4.  Thus, the area of one slant side is (1/2)(5)(4) = 10 units^2.

There are 4 such sides.  Thus, the total slant surface area is 4(10 units^2), or 40 units^2.  

If you also want to include the base area, the total would be

40 units^2 + 16 units^2 = 56 units^2.
