Answer:

2 hours

Step-by-step explanation:

given that the calorie burn rates are:

swimming: 400 cal / hour

rollerblading: 600 cal / hour

If he swims for 3 hours, he will burn:

400 cal / hour x 3 hours

= 1200 cal

Since his goal is 2400 calories, the number of calories that he has left to burn after swimming is:

2400 - 1200

= 1200 calories.

Number of hours of rollerblading to burn 1200 calories

= 1200 calories ÷ 600 calories per hour

= 2 hours

Gre4nikov [31]

Answer:

18 inches and 9 inches

Step-by-step explanation:

Given, The base of a triangle is twice of the height.

Area = 81 sq inches

Let, Base (b) = 2x

Height (h) = x

Mai's younger brother tells her that 10/7 is equal to square root of 2. Mai knows this can't be right,
Kryger [21]

Answer:

10/7 is a simple fraction, and √2 cannot be written as a simple fraction. So, they are not the same.

Step-by-step explanation:

10/7 is a number that has a numerator and a denominator.

Suppose √2 = 10/7, then √2 can also be written as a number that has a numerator and a denominator.

Since this is not the case, 10/7 cannot be the same as √2.
