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 :)

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

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

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

Answer:
y=6x+30
Step-by-step explanation:
y is the total temperature
6x is the increase of temperature by 6° per x hours
30 is the y-intercept, you start with this number
9514 1404 393
Answer:
y = 30 + 6xsee below for a graphStep-by-step explanation:
The increase in temperature is the product of the increase per hour and the number of hours: 6x.
The temperature at any time is the sum of the initial temperature (30°) and the increase (6x).
y = 30 + 6x . . . . . temperature equation
__
This is graphed as a line with an initial value of 30 and a slope of 6. (Note the attached graph has different grid line spacing vertically than horizontally.)

x = 90 - 54 = 36
Answer:
x = 36
Step-by-step explanation:
The sum of all the angles in a triangle is 180
Add the known angles together
54 + 90 = 144
then subtract 180 and 144 to find x
180 - 144 =36

find the value of x
Answer:
6x = 360-138
x= 222/6
x= 37°
Answer:
x = 42˚
Step-by-step explanation:
1) Find the angle shared by 138˚. 180-138 = 42˚.
2) Now we know that one of the angles in the pentagon is 42˚.
3) the other opposite angle is 138˚ as well.
Hopefully this makes sense! I attached a picture below.
What seems to cause an Input value to be circled?
Answer:
For inequalities, the dot would be circled in because the value is greater than or EQUAL TO or less than or EQUAL TO.
Step-by-step explanation:
For example, x > 2 would have an open circle and you are NOT including the 2 that is inputted.
For x [tex]\leq[/tex] 6, it would have a closed circle and you ARE including the 6 that is inputted.

A plant is already 43 centimeters tall, it will grow one centimeter every month. The plants height H (in centimeters) , after m month is given by the following. H=43+m , What is the height after 31 months?
Answer:
H=74 cm
Step-by-step explanation:
it grows 1 cm every month, so after 31 months, it will have grown 31 more cm.
add the 31 cm to the 43 cm it was before, and you get 74 cm

H = 43 + m
m = 31 × 1
= 31
H = 43 + 31
H = 74
