I'll do 1 and 8, and you should then be able to do 2 and 9!

For 1, we can multiply these separately - 3*4*9=108 and 5+7+2=13 (exponent multiplication is adding them!), so we have 108b^13

For 8, we can again add the exponents up to get (5/7)^8

At a local preschool there is a ratio of 3 boys to every 4 girls if there are 245 total preschoolers enrolled how many boys

JulsSmile [24]

Answer:

The total number of boys = 105

Step-by-step explanation:

The ratio of boys to girls = 3: 4

⇒ For every 3 boys, there are 4 girls.

Now, total number of students = 245

Let the common ratio of boys to girls is k.

So, 3k + 4k = 245

or , 7k = 245

⇒ k = 245/7 = 35

⇒ k = 35

Hence, the number of boys = 3k = 3 x 35 = 105

and number of girls = 4k = 4 x 35 = 140

suppose Tomas buys a total of 30 baseball and football cards in week 5 . how many of each would he have to buy to keep the same

Charra [1.4K]

Answer:

18 baseball cards
12 football cards

Step-by-step explanation:

The only relationship shown in the table is in week 1, where the ratio of baseball to football cards is ...

baseball : football = 9 : 6

In week 1, the total of these numbers is 15. You want the total in week 5 to be 30, double the total in week 1. So, Thomas needs to purchase double the numbers he purchased in week 1:

18 baseball cards
12 football cards

This table came from another question you posted, a question with no content other than the table. The blue numbers are blanks in the original table that have been filled in so as to keep the same 3:2 proportion in each week. They appear to have no bearing on this question.
