In 3 hours she will ride 22 1/2 miles. And in 1/3 of an hour she will ride 2 1/2 miles. 

Explanation: Since you already know how much she can ride in one hour, but you need to know three hours, you multiply how many miles she can bike in one hour by three. 
7 1/2 x 3 = 15/2 x 1/3 = 45/2 = 22 1/2

Then to find how much she can bike in 1/3 of an hour, you multiply 7 1/2, the amount of one hour, by 1/3, the amount of time. 
7 1/2 x 1/3 = 15/2 x 1/3 = 15/6= 2 3/6 = 2 1/2 

(And in case you don't know how to multiply fractions, whole, and mixed numbers then here: make all numbers into fractions [both proper and improper], and then just multiply across or cross cancel if possible. Simplify if necessary.)

Use the net to find the lateral area of the prism.
Gnesinka [82]

Answer:

The lateral area = 450 mm²

Step-by-step explanation:

The lateral area of any prism is equal to the areas of the sides faces

∵ The base of the prism is triangle

∴ It has 3 side faces

∵ The lengths of the side faces are 5 , 12 , 13 and their height is 15

∴ The lateral area = (5 × 15) + (12 × 15) + (13 × 15)

                              = 75 + 180 + 195 = 450 mm²

Find the value of the variables please please help me out I will mark you the brainly! Please please
RSB [31]

Answer:

m = 54

Step-by-step explanation:

The secant- secant angle 20° is half the difference of the intercepted arcs, that is

\frac{1}{2} (160 - 2m - 12) = 20° ( multiply both sides by 2 to clear the fraction )

- 2m + 148 = 40° ( subtract 148 from both sides )

- 2m = - 108 ( divide both sides by - 2 )

m = 54
