Answer:

6 hours

Step-by-step explanation:

We can use ratios to solve

10 hours           x hours

-------------- = -------------

15 logs            9 logs

Using cross products

90 = 15x

Divide by 15

90/15 = 15x/15

6 = x

6 hours

Answer:

Below

Step-by-step explanation:

Jovie has maintained the fire burning with 15 logs for 10 hours.

● 15 => 10

Let's find how many hours do 9 logs keep the fire burning.

Let x be that time

● 9 => x

■■■■■■■■■■■■■■■■■■■■■■■■■■

● 15 => 10

● 9 => x

● 15 * x = 9×10

● 15x = 90

● x = 90/15

● x = 6

So the time that the fire will keep burning is 6 hours.

Stephanie wants to buy s tomato plants.
max2010maxim [7]

Answer:

Required Expression : 7·(s + d) - 25

Step-by-step explanation :

Cost of each plant both buys = $7

No. of plants Stephanie wants to buy = s

Total cost of plants bought by Stephanie = 7·s

No. of plants Diego wants to buy = d

Total cost of plants bought by Diego = 7·d

Total cost = 7·s + 7·d

                 = 7·(s + d)

Discount applied through coupon = $25

So, Total cost of all their plants with discount = 7·(s + d) - 25

Which point on the number line best represents√57?
Cerrena [4.2K]

Answer:

8.

Step-by-step explanation:

\sqrt{57} =\sqrt{3 * 19}

Since this cannot be further simplified, we will calculate the square root of 57 with our calculators.

We find that the square root of 57 is 7.549834435, and since the tenths place is a 5, we will round up to the next whole number. So, the point on the number line that best represents the square root of 57 is 8.

Hope this helps!
