There are 48 students who play the clarinet in a year group of 120.
Write this proportion as a percentage.
Answer:
40%
Step-by-step explanation:
As a Fraction your answer would be [tex]\frac{48}{120}[/tex].
However we are looking for it as a percentage.
In order to calculate, this you can simply find 10%, and 5% of 120.
10% = 12
5% = 6
48 is divisible by 12, therefore 48 / 12 = 4
Giving you your answer which is 40%.

your family went out to dinner to celebrate your grandmas 100th birthday. The total for the dinner was $208.60, so your parents left a $31.29 tip. What percent of the bill was the tip?
Answer:
[tex]\%Tip = 13.04\%[/tex]
Step-by-step explanation:
Given
[tex]Tip= \$31.29[/tex]
[tex]Bill = \$208.60[/tex]
Required
Determine the percentage of the tip
First, we calculate the amount paid
[tex]Amount = Tip + Bill[/tex]
[tex]Amount = \$31.29 + \$208.60[/tex]
[tex]Amount = \$239.89[/tex]
The percentage of the tip is then calculated using:
[tex]\%Tip = \frac{Tip}{Amount} * 100\%[/tex]
[tex]\%Tip = \frac{31.29}{239.89} * 100\%[/tex]
[tex]\%Tip = \frac{31.29* 100}{239.89} \%[/tex]
[tex]\%Tip = \frac{3129}{239.89} \%[/tex]
[tex]\%Tip = 13.04\%[/tex]

4) 4x + 3y = 56
2x + y = 24
Solve using elimination please show work
Answer:
x = 8 y = 8
Step-by-step explanation:
Multiply 2nd equation by -3 to get -6x - 3y = -72
Now 4x + 3y = 56
-6x - 3y = -72
-2x = -16
x = 8
Substitute x = 8 into the 2nd equation
2(8) + y = 24
16 + y = 24
y = 8
Check: Substitute the values into the 1st equation
4(8) + 3(8) = 32 + 24 = 56 So we have the correct values for x and y

Find the measure of the angle, θ, where 0° ≤ θ ≤ 90°.
sinθ = 1/2
Answer:
[tex]\theta = 30^{\circ}[/tex]
Step-by-step explanation:
Given:
Range: [tex]0^{\circ} \le \theta \le 90^{\circ}[/tex]
[tex]Sin \theta = \frac{1}{2}[/tex]
Required
Find [tex]\theta[/tex]
[tex]Sin \theta = \frac{1}{2}[/tex]
Take arcsin of both sides
[tex]sin^{-1}(sin\theta) = sin^{-1}(\frac{1}{2})[/tex]
[tex]\theta = sin^{-1}(\frac{1}{2})[/tex]
Using the sin table
[tex]\theta = 30^{\circ}[/tex]

What is the intercept of
y=-1/2x-1 and y=1/4x-4
Answer: The y-intercept of y = -1/2x -1 is (0,-1)
The y-intercept of y = 1/4x -4 is (0,-4)
The attachment shows the graph of these equations.
Step-by-step explanation:
Both equations are in slope-intercept form. y = mx + b
The constant, b, is the y-intercept.
The y-intercept of y = 1/2x -1 is (0,-1)
The y-intercept of y = 1/4x -4 is (0,-4)
What is y- intercept?On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.
Given:
y=-1/2x-1 and y=1/4x-4
For Finding the y- intercept put x= 0 we get
y = -1/2(0) -1
y= 0- 1
y= -1.
For Finding the y- intercept put x= 0 we get
y=1/4(0)-4
y= 0- 4
y= -4
