The ratio of girls to boys in Liza's classroom is 5 to 4.
How many girls are in her classroom if there is a total of 27 students?
Hi!
The answer is: 15 girls.
__________________________________________________________
Let
x-----> the number of girls
y-----> the number of boys
we know that
- x+y=27, Which is equation A.
- x/y = 5/4
- isolate the variable y
- y=4/5x, Which is equation B.
- 9/5x=27
- x=5x27/9
- 15 Girls.

Find the value of x that makes m ∥ n.
Answer:
x=60
Step-by-step explanation:
X+2x=180degree because it is co interior angle
3x=180
X=180/3
X=60.
Verification
X+2x=180
60+2(60)=180
60+120=180

Answer:
Wal-mart.
Step-by-step explanation
20% of 225 is 45, therefore we subtract 45 from 225 and get 180.
180x4=$720
$720 is the least amount of money spent on 4 tires :)

Select the correct answer from each drop-down menu. The velocity, v, in meters/second, of an object with a mass of m, in kilograms, and kinetic energy of K, in joules, is given by this equation. Use the equation to complete this statement. The kinetic energy of a ball with a mass of 2 kilograms that is rolling at a velocity of 5 meters/second is joules.
Answer:
25
Step-by-step explanation:
The kinetic energy of a ball with a mass of 2 kg that is rolling at a velocity of 5 m/s is 5 Joules
Calculating Kinetic energyFrom the question, we are to determine the kinetic energy of the ball
From the given equation for the velocity,
[tex]v = \sqrt{\frac{2K}{m} }[/tex]
We will make K the subject of the equation
[tex]v = \sqrt{\frac{2K}{m} }[/tex]
Take the squares of both sides
[tex]v^{2} ={\frac{2K}{m} }[/tex]
Multiply both sides by m
[tex]mv^{2} ={\frac{2K}{m} } \times m[/tex]
[tex]mv^{2} =2K[/tex]
∴ [tex]K = \frac{1}{2} mv^{2}[/tex]
Now, for the kinetic energy of a ball with a mass of 2 kilograms that is rolling at a velocity of 5 meters/second
That is,
m = 2 kg
and v = 5 m/s
Putting the parameters into the equation, we get
[tex]K = \frac{1}{2} \times 2 \times 5^{2}[/tex]
K = 25 J
Hence, the kinetic energy of a ball with a mass of 2 kg that is rolling at a velocity of 5 m/s is 5 Joules

Find the Error A student graphs the relationship y = x on a coordinate plane. She says the slope is O because there is no coefficient. Find her
mistake and correct it.
Answer:
y=x times factor of 12 abstracted by -93
Step-by-step explanation:
The slope is the ratio of y's coordinate to x's coordinate thus the slope of y = x will be y/x = 1.
What is the slope?A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
A linear equation or function is given as ;
y = mx + b
Now,
At x = 0 ⇒ y = b so it will be a y-intercept.
As per the given, y = x
The x's coefficient is 1 thus slope will be 1.
Or, y/x = 1
Hence "The slope is the ratio of y's coordinate to x's coordinate thus the slope of y = x will be y/x = 1".

What is the equation of the line that passes through the point (5,6) and has a slope of 2 ?
Answer:
y = 2x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation
To find c substitute (5, 6) into the partial equation
6 = 10 + c ⇒ c = 6 - 10 = - 4
y = 2x - 4 ← equation of line

A square root function, that is stretched by a factor of 3, and shifted 4 units left and 6 units up.
Answer:
The square root function will turn to;
y = 3 √(x + 4) + 6
Step-by-step explanation:
Let the square root function be ;
y = √x
Now, let’s stretch this by a factor of 3
This means we are dilating by a factor of 3
Mathematically, this will be
y = 3 * √x = 3 √x
Shifting this 4 units up means that we are extending the x-axis value by 4 units
That will be ;
y = 3 √x + 4)
Now shifting this 6 units up, we finally will have;
y = 3 √(x + 4) + 6
