What is the relationship between segments?
Answer:
When you have intersecting segments such as these, the relationship is that the product of the segment pieces of one segment is equal to the product of the segment pieces of the other. You can use this relationship to help you solve problems that ask you find the length of a missing segment piece.
The ratio of boys to girls in the ninth grade is 6:5. If there are 185 girls in the class, how many boys are there?
Answer:
[tex]222[/tex] boys
Step-by-step explanation:
Let [tex]x[/tex] = total number of ninth graders. By knowing how many students there are in the grade, we can find for the number of boys.
[tex]\frac{5}{6+5}x = 185[/tex] (number of girls in ninth grade)
[tex]\frac{5}{11}x = 185[/tex]
[tex]x=407[/tex]
To find for the number of boys, we can use substitution:
[tex]\frac{6}{6+5}x = \frac{6}{11}(407)[/tex]
[tex]=222[/tex]
∴ There are [tex]222[/tex] boys in the class.
Hope this helps :)

Visitors to a cinema are either children, adults or pensioners the ratio of children to adult visitors is 1 : 2 the ratio of adults to pensioners is 3 : 4 a stratified sample is to be taken from the cinema visitors how many pensioners should be in the sample?
Answer:
the number of pensioners in the sample is 40
Step-by-step explanation:
The computation of the number of pensioners in the sample is shown below:
Given that
The Ratio of children to adult visitors is 1:2
The ratio of adults to pensioners is 3:4
And, the total number of seats is 85
Based on the above information,
The common ratios we could write as
1.5 : 3 : 4
Now we doubled it
3 : 6 : 8
So, the number of pensioners in the sample is
= 85 × 8 ÷ (3 + 6 +8)
= 40
Hence, the number of pensioners in the sample is 40

Find the slope when given the following points.
(2, 1) and (5, 3)
Answer:
2/3
Step-by-step explanation:
We can find the slope using
m = ( y2-y1)/(x2-x1)
= ( 3-1)/(5-2)
= 2/3
Answer:
2/3
Step-by-step explanation:
Use the equation y2-y1/x2-x1
So, 3-1/5-2
2/3

12x-9=10x-15 Help me answer this please
Answer:
x = -3
Step-by-step explanation:
Given:
12x - 9 = 10x - 15
Now, let's add 15 to both sides of the equation.
12x + 6 = 10x
Now, let's subtract 12x from both sides of the equation.
6 = -2x
Now, let's divide both sides by -2.
-3 = x
A rectangle has the are of 60 inch2. What can be its dimensions? Copy and fill in the chart.
Answer:
In order of the blanks from left to right, 30; 6; 2; 1/2; 20; 12; 12; 3/5
Step-by-step explanation:
So the rectangle has an area of 60 inches squared & the equation for the area of a rectangle is width * height. So, you can find the missing term if you just take 60 & divide it by the given number.
60/2 = 30
60/10 = 6
60/30 = 2
60/120 = 1/2
60/3 = 20
60/5 = 12
60/5 = 12
60/100 = 3/5
