The ratio of girls to boys in a sports club is 3: 5
There are 27 girls in the club. How many boys are there?
Answer:
45 boys
Step-by-step explanation:
The 3 part of the ratio refers to the number of girls.
Divide number of girls by 3 to find the value of one part of the ratio
27 ÷ 3 = 9 ← value of 1 part of the ratio, then
5 parts = 5 × 9 = 45 ← number of boys
Answer:
Their are 45 boys.
Step-by-step explanation:
Let's represent Girls by G,and Boys by B
so G = 27 and B = ? and G/B = 3:5 or 3/5
3 = 27
5. B
3B = 135
3. 3
B = 45
FIND THE equation of the linear function represented by the table below in slope intercept form
Answer:
y= -2x - 1
Step-by-step explanation:
Take two of the points given by the data in the table.
Using the x-values 1 and 2, they have a y-value of -3 and -5, respectively.
Therefore, we can write these out as coordinate points: (1, -3) and (2, -5).
The equation to find the slope of a line is:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]Substitute these points into this formula to find the slope of this linear function.
[tex]\displaystyle m= \frac{-5-(-3)}{2-1}[/tex]Simplify and solve for the slope m.
[tex]\displaystyle m=\frac{-2}{1} =-2[/tex]The slope of this linear function is -2. Now, we can use this slope and substitute it into the point-slope equation along with another one of the points on the function.
Point-slope equation:
[tex]y-y_1=m(x-x_1)[/tex]Substitute m = -2 and the point (1, -3) into this equation.
[tex]y-(-3)=-2(x-1)[/tex]Simplify this equation and put it into slope-intercept form: [tex]y=mx+b[/tex].
[tex]y+3=-2x+2[/tex] [tex]y=-2x-1[/tex]The equation of the linear function represented by the table is y = -2x - 1.
Answer:
y= -2x - 1
Step-by-step explanation:
Take two of the points given by the data in the table.
Using the x-values 1 and 2, they have a y-value of -3 and -5, respectively.
Therefore, we can write these out as coordinate points: (1, -3) and (2, -5).
The equation to find the slope of a line is:
Substitute these points into this formula to find the slope of this linear function.
Simplify and solve for the slope m.
The slope of this linear function is -2. Now, we can use this slope and substitute it into the point-slope equation along with another one of the points on the function.

Substitute m = -2 and the point (1, -3) into this equation.
Simplify this equation and put it into slope-intercept form: .
The equation of the linear function represented by the table is y = -2x - 1.

Answer:
the measure of the angle is 72
x=36
Step-by-step explanation:
we can make an algebraic equation using the info given
2x+80=152
2x=72
x=36
the measure of the angle is 72
Answer:
x = 36, the measure of the angle is 72
Step-by-step explanation:
We can see this because Angle 2x and Angle 72 are verticle angles. Based on this information we know that verticle angles are congruent to each other, meaning the are the same. So that leaves us with an equation to figure out x.
2x = 72
[tex]\frac{2x}{2}[/tex] = [tex]\frac{72}{2}[/tex]
x = 36

What is the slope of the line on the graph?
Answer:
5
Step-by-step explanation:
the slope is the change in y divided by the change in x
as y goes up 5 x goes up 1
5/1=5 so the slope is 5
Answer:
6
Step-by-step explanation:
To find the slope you use rise over run.
Count how far each of the dots are from each other and you should get 6. That is your rise. See how far it goes to the right or left and you should get 1, which is your run.
Since it is rise over run, it would be 6/1, which makes your answer 6

How to Simplify a Ratio A : B when A and B are both whole numbers:
List the factors of AList the factors of BFind the greatest common factor of A and B, GCF(A, B)Divide A and B each by the GCFUse the whole number results to rewrite the ratio in simplest formTry to reduce the ratio further with the greatest common factor (GCF).
The GCF of 14 and 4 is 2
Divide both terms by the GCF, 2:
14 ÷ 2 = 7
4 ÷ 2 = 2
The ratio 14 : 4 can be reduced to lowest terms by dividing both terms by the GCF = 2 :
14 : 4 = 7 : 2

How many times bigger is 315 compared to 312?
Do not include units (times bigger) in your answer.
Answer:
105/104
Step-by-step explanation:
you divide 315 divided by 312 and you get 105/104.
to check it you do 312 times 105/104 and you get 315 to be your answer! Hope this helps ;)
105/104 times the number 315 bigger than the number 312.
What is multiplication?Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.
The given numbers are 315 and 312.
Number of times 315 is bigger compared to 312 is
315/312
= 105/104
Hence, 105/104 times the number 315 bigger than the number 312.
