KATRIN_1 [288]3 years ago
7 0

Answer:

Step-by-step explanation: first write it as an equation f(x)=15(x) +45 and then plug in 3 because you are finding for 3 hours. It would look like this f(3)=15(3) + 45. Then you solve it, 15 times 3 equals 45. f(3) =45+45 and then add f(3)=45+45. And the answer is f(3)=90. HOPE THAT HELPS.

The sum of two numbers is 80 . The ratio of those two numbers is 3:5 find the larger Number
Oksana_A [137]

Answer:

the larger number is 50

Step-by-step explanation:

Notice there are two unknown numbers. Let's address the smaller one as x and the larger one as y. now we can write two equations from translating the phrases given into algebraic expressions:

"the sum of two numbers is 80" can be written as:

x+y=80

Now the second phrase:

"The ratio of those two numbers is 3/5"

Notice here that in our ratio we need to use our small number (x) in the numerator of the quotient, and the larger number (y) in the denominator to make it in agreement with the small and larger numbers of the ratio \frac{3}{5}, and solve for x:

\frac{x}{y} = \frac{3}{5} \\x= \frac{3}{5}y

Replace the value of x we just obtained in the first equation we wrote, so we obtain one equation with only one unknown hat we should be able to solve:

x+y=80\\\frac{3}{5} y+y=80\\\frac{3}{5} y+\frac{5}{5} y=80\\\frac{8}{5}y=80 \\8y=80*5\\8y=400\\y=\frac{400}{8} \\y=50

Therefore the larger number (y) equals 50.

Mr. Hoya brought 5 watermelons from his grocery store. The watermelons weighed 8.25 pounds, 9.25 pounds, 8.875 pounds, 9.625 pou
Ronch [10]
The first thing we must do for this case is to find the total weight of the watermelons.
 We have then:
 W = 8.25 + 9.25 + 8.875 + 9.625 + 10.75

 W = 46.75 pounds
 We now look for the amount of watermelons that people ate.
 We have then:
 (0.25) * (153) = 38.25 pounds

 Therefore, the amount of watermelon remaining is:
 46.75 - 38.25 = 8.5 pounds

 We note that the amount of watermelon remaining is equal to 8.5 pounds.
 Answer:
 
the amount of leftover watermelon is: equal to 8.5 pounds
