Answer:

Step-by-step explanation:

The 2 figures are similar so corresponding sides are in the same ratio.

The factor is the value that you have to multiply a side in the first rectangle to get the corresponding side in the second rectangle.

12 ----> 9

So:

12 * f = 9 where f is the factor

f = 9/12 = 3/4.

One pound of swordfish costs as much as 1.5 pounds of salmon. Mrs. O pays $39 for 2 pounds of salmon and 3 pounds of swordfish.

Dimas [21]

Answer:

The ratio of the amount for swordfish to the amount of salmon is 6:4

Step-by-step explanation:

Given as :

The price for 1 pound of swordfish = The price of 1.5 pound of salmon

So, On this relation

The price for ( 1 × 2 ) pound of swordfish = The price of ( 1.5× 2 ) pound of salmon

i.e The price for 2 pound of swordfish = The price of 3 pound of salmon

Now According to question

Mrs. O pay the total money for 2 pounds of swordfish and 3 pound of salmon = $ 39

Let the money she pay for swordfish = 2 sw

And The money she pay for salmon = 3 sa

∵, The total money she pay for both = $ 39

I.e 2 sw + 3 sa = 39

As 2 sw = 3 sa

So, 3 sa + 3 sa = 39

Or, 6 sa = 39

or, sa = $\frac{39}{6}$ = $\frac{13}{2}$

∴ sw = $\frac{13}{2}$ × $\frac{3}{2}$

or, sw = $\frac{39}{4}$

Now, the ratio of the amount for swordfish to the amount of salmon = $\frac{\frac{39}{4}}{\frac{13}{2}}$

I.e The ratio = $\frac{6}{4}$

Hence The ratio of the amount for swordfish to the amount of salmon is 6:4

Select the correct answer. What is the range of this data? (3,3, 0, 8, 7, 10, 2, 6, 12, 0}

Natasha2012 [34]

Answer:

D: 12

Step-by-step explanation:

The range is the difference between the largest value in the date minus the smallest value in the data.

In this set of numbers given, the largest value is 12 and the smallest value is 0

so: 12-0 = 12

The range of this data is 12

A tour group with 44 people in it is getting rooms in a motel to stay in for the night. no more than 5 people can stay in each r

Anna11 [10]

Hello!

Since we want to find out how many rooms will be needed for 44 people, we must use division.

44 ÷ 5 = 8.8

Check by multiplying:

5 × 8 = 40

Because 40 is less than the amount of people (44), we'll need to multiply by the next number in line (9):

5 × 9 = 45 (1 extra person, no biggie!)

The tour group will need 9 rooms.
