MK is the segment bisector of RS Find the length of RS.

The length of RS is?

Answers

Answer:

m(RS) = 34

Step-by-step explanation:

Since, MK is the segment bisector of RS.

Therefore, segment MK will bisect RS in two equal segments RM and MS.

RM ≅ MS

m(RM) = m(SM) = 17

m(RM) + m(SM) = m(RS)

m(RS) = 17 + 17

m(RS) = 34

A hair stylist has three colors of hair dye. She has 4 bottles of chestnut, 7 bottles of blond, and 8 bottles of cherry. What does the ratio 8:19 represent in this situation? Explain your reasoning. Include a model in your explanation. ​

Answers

Answer:

The 8:19 ratio is the bottles of cherry to the total amounts of bottles

Step-by-step explanation:

im not sure what a model would look like but here's one part of the question

The ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.

What is ratio?Ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that a hair stylist has three colors of hair dye. She has 4 bottles of chestnut, 7 bottles of blond, and 8 bottles of cherry.

Total number of bottles = 8 + 7 + 4 = 19

Total number of cherry bottles = 8

The ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.

Therefore, the ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.

At a football game
number of men : number of women : number of children = 13: 5:7
There are 4152 more men than women.
Work out the number of children at the game.

Answers

1884 i think the answer is-
The ratio of men to women at the game is 13:5. The difference between the number of men and women is 4152. Subtract 5 from 13 to work out the difference between the ratio value of men and women. 13-5=8. Divide 4152 by 8 to work out how many people 1 in the ratio represents. Then times this value (which is 519) by 7 (the ratio value for children) to work out the total number of children at the game. 519×7= 3633.

Answer:

a) t = -7

b) f = 12

c) k = -13

Step-by-step explanation:

a) t + 11 = 4

t = -7

b) f = 8+4

f = 12

c) 5 = 18 + k

-13 = k

Answer:

A= -7

B= 12

C= -13

Step-by-step explanation:

This is how I do it

A) Subtract 4 from each side, and when you do that you get 7=-t which makes the answer -7.

B) Add 8 to both sides and you get f=12.

C) Subtract 5 from each side, and when you do that you get -k=13 which makes the answer -13.
