Answer:
There are 24 right handed students
Step-by-step explanation:
This is a ratio question so it would be represented as 1:4.
First you would do 1 + 4 which is 5.
Then do 30 ÷ 5 which is 6.
Finally multiply 6 by 4 and 1.
So 6 × 4 × 1 is 24.
So there are 24 students who are right handed.
Hope this makes sense!
What is the unit rate if the candy is $7.80 for 2 pounds?
Answer:
= 3.9 candy per pound
Step-by-step explanation:
This is a fraction equal to
7.8 candy ÷ 2 pounds
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2
7.8 candy ÷ 2
________
2 pounds ÷ 2
=
3.9 candy
_______
1 pound
=
3.9 candy

If b^2=a then b is what of a?
Answer:
[tex]\huge\boxed{b = \sqrt{a}}[/tex]
Step-by-step explanation:
If we have an equation [tex]b^2 = a[/tex] and we want to find what b is in relation to a, we can change the equation so that we have b on one side and whatever is on the other side is what b is.
[tex]b^2 = a[/tex]
To isolate b, we can take the square root of both sides as taking the square root of something squared results in the base.
[tex]\sqrt{b^2} = \sqrt{a}[/tex]
[tex]b = \sqrt{a}[/tex]
So b is the square root of a.
Hope this helped!

X intercepts are when y = 0, set the equation equal to zero and solve:
0 = -x^3 +x^2 + x -1
-x^3 + x^2 = -x
-x + x = 0
0-1 = -1
The first one is (-1,0)
Because the equation contains squares the answer could also be opposite, so the other answer would be (1,0)
The two answers are (-1,0) (1,0)
When you calculate In (100), you would be finding the value of which of the following expressions?
log(100)
loge (100)
log100 (e)
log10(100)
Given the log function ln(100), this can therefore be written as loge(100)

The graph shows the proportional relationship between the number of sodas you buy and the cost of the sodas. Explain what the constant of proportionality (k), means in the context of the situation.
A: 4 sodas cost $6
B: One soda cost $7
C: One soda cost $2
D: One soda cost $4
E: 3 sodas cost $1
Answer:
C: One soda cost $2
Step-by-step explanation:
One soda costs $2. As you can see, which each soda you buy, X and Y go up by two. The relationship of X and Y is x=2y, with X being sodas and Y being dollars

Answer:

Step-by-step explanation:
If two adjacent angle formed a straight line, then the two angles formed a pair of linear anglesThe sum of the measures of the linear angles is 180°From the given figure
∵ The angles of measures (9x - 7)° and (4x - 8)° are adjacent angles
∵ The angles of measures (9x - 7)° and (4x - 8)° formed a line
∴ They formed a pair of linear angles
∵ The sum of the measures of the linear angles is 180°
→ That means add them and equate the sum by 180
∴ (9x - 7) + (4x - 8) = 180
→ Add the like terms
∵ (9x + 4x) + (-7 + -8) = 180
∴ 13x + (-15) = 180
→ Remember (+)(-) = (-)
∴ 13x - 15 = 180
→ Add 15 to both sides
∴ 13x - 15 + 15 = 180 + 15
∴ 13x = 195
→ Divide both sides by 13
∵ [tex]\frac{13x}{13}[/tex] = [tex]\frac{195}{13}[/tex]
∴ x = 15
∵ Lines m and n are parallels
∵ A line intersected them
∵ The angles of measures (2y + 2), (9x - 7) are interior alternate angles
∵ The interior alternate angles are equal in measures
∴ 2y + 2 = 9x - 7
∵ x = 15
→ Substitute the value of x
∴ 2y + 2 = 9(15) - 7
∴ 2y + 2 = 135 - 7
∴ 2y + 2 = 128
→ Subtract 2 from both sides
∴ 2y + 2 - 2 = 128 - 2
∴ 2y = 126
→ Divide both sides by 2
∴ [tex]\frac{2y}{2}[/tex] = [tex]\frac{126}{2}[/tex]
∴ y = 63
The values of x and y are 15 and 63, respectively
The angles in the figure are: (9x - 7)° and (4x - 8)°
These angles are adjacent angles.
So, we have:
[tex]\mathbf{9x - 7 + 4x - 8 = 180}[/tex]
Collect like terms
[tex]\mathbf{9x + 4x = 180 + 8 + 7}[/tex]
[tex]\mathbf{13x = 195}[/tex]
Divide both sides by 13
[tex]\mathbf{x = \frac{195}{13}}[/tex]
[tex]\mathbf{x = 15}[/tex]
Also, we have:
[tex]\mathbf{2y + 2 = 9x - 7}[/tex] -- interior angles
Subtract 2 from both sides
[tex]\mathbf{2y = 9x - 9}[/tex]
Substitute 15 for x
[tex]\mathbf{2y = 9\times 15 - 9}[/tex]
[tex]\mathbf{2y = 126}[/tex]
Divide both sides by 2
[tex]\mathbf{y = 63}[/tex]
Hence, the values of x and y are 15 and 63, respectively

The ratio of soccer balls to basketballs at Andrew’s school is shown on the ratio table. What number completes the ratio table to make an equivalent ratio? [Type your answer as a number.]
soccer balls 30 __?
basket balls 25 5
Answer:
Step-by-step explanation:
You can set this up as a proportion
30/25 = x/5
Cross multiply
25*x = 30*5
25*x = 150
x = 150/25
x = 6
Answer:
30 to 150
25 to 5
Step-by-step explanation:
if there are 25 basketballs for every 5 soccer balls, that means that there is 1 soccer ball for every 5 basketballs. so to get how many soccer balls to basket balls, you would multiply 30 by 5 to get 150. For every 30 soccer balls there are 150 basketballs.

the length of a rectangle is five times its width. if the perimeter of the rectangle is 96 ft, find its area.
Answer:
lets say that the length is L and the width is W. With the given info, we can say that L=5W.
We know that the perimeter is all four sides added, so..
5W*4=20W
20W=96
W=4.8
L= 5*4.8=24
Area is equal to 24*4.8, which is 115.2
Voila! Your answer is 115.2 sq. ft!

A test is worth 60 points. Multiple-choice questions are worth 2 points, and
short-answer questions are worth 5 points. If the test has 15 questions, how
many multiple-choice questions are there?
O A. 2m+ 5s = 60
B. m + s = 60
O C. 2m + 5s +15 = 60
O D. 2m + 5s = 15
Answer:
Step-by-step explanation:
Let the number of MC questions = x
Let the number of SA questions = y
x + y = 15
2x + 5y = 60
Multiply the top equation by 2
2x + 2y = 30
Put this underneath the second equation and subtract
2x + 5y = 60
2x + 2y = 30 Subtract
3y = 30
y = 10 Subtract
2y = 20
y = 10
x + y = 15
x + 10 = 15
x = 5
