Brand X costs $2.70 for 10 ounces. Brand Y costs 4 cents more per ounces. What is the cost of 11 ounces of brand Y?

Ksju [112]

Well you have to first find the constant of Brand X which would be 2.70/10 = .27. Brand Y is .4 more so that would be .31 per ounce. So then .31 x 11 = 3.41. The cost of 11 ounces of brand Y is $3.41.

Convert 39°C to degrees Fahrenheit.

posledela

Given a temperature C in celsius, you can convert it to Fahrenheit by using the formula

$F=32 + \dfrac{9C}{5}$

In your case C=39, so you have

$F = 32 + \dfrac{9\cdot 39}{5} = 32+70.2=102.2$

Two planes just took off from St. Louis, MO. The first plane is traveling 3.5 times as fast as the second plane. After Traveling

Yanka [14]

Answer:

Speed of first plane is 350 miles per hour

Speed of second plane is 100 miles per hour

Step-by-step explanation:

Let the speed of the second plane be X

Then the speed of the first plane will be 3.5 X

Distance travelled by first plane is 9.5 *X

Distance travelled by second plane is 9.5 * 3.5 X

Difference of distance between the two plane is

$9.5 * 3.5 X - 9.5 *X = 2375\\23.75 X = 2375\\X = 100$ miles per hour

Speed of first plane is 3.5 *100 = 350 miles per hour

Speed of second plane is 100 miles per hour
