6th grade math , help pleasee:)

C

Step-by-step explanation:

15 mins to 50 mins(part/whole) and divide everything by 5

B. 1 : 2

Step-by-step explanation:

Add up how much time he spent doing each exercise to find the total number of minutes for his workout.

10 + 25 + 15 = 50 minutes

He spent 25 minutes lifting weights. So, the ratio is:

25 : 50

Now simplify by dividing each side by 25.

25 : 50

= 1 : 2

The ratio of the number of minutes he lifted weights to the total number of minutes of his entire workout is 1 : 2.

Hope that helps.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
