Answer 1

Answer: you have to make the fraction into an integer. the simplest version of a ratio involves the smallest possible integers. therefore, 5:2.5 will equal 10:5 (you multiply both sides by 2). 10:5 cancels down to 2:1. hope this helped :)

A leatherback sea turtle can travel at a speed of 48 miles in 8 hours. How many miles can this turtle travel in 10 hours?

Answers

Answer:

60 miles can leatherback sea turtle travel in 10 hours .

Step-by-step explanation:

As given

A leatherback sea turtle can travel at a speed of 48 miles in 8 hours.

i.e

48 miles = 8 hours

A leatherback sea turtle can travel in one hour.

$1\ hour = (48)/(8)\ miles$

1hour = 6 miles

Now calculate for the 10 hours .

A leatherback sea turtle travel distance in 10 hours = 6 × 10

= 60 miles

Therefore 60 miles can leatherback sea turtle travel in 10 hours .

Evaluate and simplify cos 2pi/3. The options for answers are in the picture attachment, but I have NO idea how to get any of them? Please, Any help is appreciated (:

Answers

when pi is inside the trigonometric function you can subs. it by 180 degree
so cos(2*180/3) = cos(120) = -0.5

Are the triangles similar? If they are, identify the similarity ratio.A) Yes; the similarity ratio is 3:4.
B) Yes; the similarity ratio is 2:3.
C) Yes; the similarity ratio is 1:2.
D) No; the triangles are not similar.

Answers

A, because if you match the left triangle's sides to the right triangle's sides and simplify the fractions the ratio is 3/4. 6/8= 3/4, 9/12=3/4. and 12/16=3/4

mike drove to a frineds house at the rage of 40 mph. he returned hoke by the dsne route at 45 mph the driving time for the round trip was four hours how long did it take mike to get home

Answers

Let the distance be x miles

Time = Distance / speed

Time taken by Mike to go to his friend's house = x / 40 hours

Time taken by him to return = x / 45 hours

Total time = x / 40 + x / 45 = 4 hours

= 9x + 8x = 1440 miles

17x = 1440

= x = 1440 ÷ 7

= x = 84.706

Time taken to return home = 84.706 /45= 1.882 hours .

Therefore , Mike took1.882hoursto reach home .
