Every hour, a machine makes the same number of tennis racquets. If on the 3rd hour of running, the machine has made 240 racquets, and on the 5th hour of running it has made 400 racquets, what is machines production rate?
A
80 racquets per hour
B
100 racquets per hour
C
120 racquets per hour
D
140 racquets per hour
Answer:
80 racquets per hour.
Step-by-step explanation:
Divide 240 by 3, and you'll get 80. To double check, divide 400 by 5 and you'll still get 80. Hope that helps.

Jessica used Fraction 2 over 3 yard of fabric to make a scarf. Can she make 2 of these scarves with Fraction 1 and 3 over 4 yards of fabric, and why?
A. Yes, because the quotient of Fraction 1 and 3 over 4 ÷ fraction 2 over 3 is 2 and 5 over 8
B. No, because the quotient of Fraction 2 over 3 ÷ Fraction 1 and 3 over 4 is 1 and 2 over 12
C. No, because the quotient of Fraction 1 and 3 over 4 ÷ fraction 2 over 3 is 1 and 2 over 12
D. Yes, because the quotient of Fraction 2 over 3 ÷ Fraction 1 and 3 over 4 is 2 and 5 over 8
Please help, and thanks so much!
2/3 yard of fabric = 2 feet of this fabric = which is used to make 1 scarf
1 3/4 yards = ?
1 yard = 3 feet = 36 inches
3/4 of 36
36 /4 = 9
9 * 3 = 27
36 + 27 = 63
63 inches of fabric would mean that she can 2 scarves as 2 scarves would use 48 inches or 4 feet as 1 scarf uses 2 feet. She will also have 15 inches of extra fabric.

Find the measures of the interior angles of the triangle.
Answer:
X = 45
Step-by-step explanation:
Answer:
m∠A = 45 degrees
m∠B = 110 degrees
m∠C= 25 degrees
Step-by-step explanation:
In a triangle, all interior angles add up to 180, which means:
x + x+65 + 25 = 180
2x + 90 = 180
2x = 90
x = 45
m∠A = 45
m∠B = (45+65) = 110
m∠C= 25
Jane has $55 to buy gifts and to pay for lunch. Each gift costs $12 and lunch costs $7. Write an inequality that can be used to determine how many gifts, g, Jane can buy.
Answer:

Step-by-step explanation:
help please!!! ty ;D
Answer:
Jane is 52 7/40 inches tall
Step-by-step explanation:
What you do is you subtract 1 3/8 from 54 3/4 which gives you Carl's height, which is 53 3/8.
Lastly, you subtract 1 1/5 from 53 3/8 which is 52 7/40.
Answer: 52 7/40

18/20
15/20
20/20=1 help please
Answer:
20/20: D
Step-by-step explanation:
First turn both the fractions into twentieths.
3/5 = 12/20
8/20
Then add 12/20+8/20=20/20
20/20 = 1

solve for x: 5x - 2 = 3x + 8
Answer:
x = 5
Step-by-step explanation:
To solve for x in 5x - 2 = 3x + 8 start by getting the variables on the same side. To do this, subtract 3x from 5x. (you always do the opposite of the term's operation)
2x - 2 = 8 now add 2 to 8
2x = 10 now divide 2
x = 5

Answer:
A and D are functions
Step-by-step explanation:
A is a function because each output is going down the same amount each time, in this case, going down by 4. (the function here is y = -x + 11)
B is not a function because there isn't a constant for y.
C isn't a function either because two x's are 0 with different y values, and you can't have that in a function.
D is also a function because of the equation on the right side.
The red line of the attachment below in A's function graphed, and the lime curve represents D's function graphed.

What is the equation of the line that has a slope of m = 2 and passes through the point (-5, -6)?
Answer:
[tex]y=2x+4[/tex]
Step-by-step explanation:
You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, or insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)
Point-slope form:
[tex]y-y_{1}=m(x-x_{1})[/tex]
Where:
[tex]m[/tex] is the slope[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are corresponding coordinate points [tex](x,y)[/tex]Insert the given values:
[tex]m=2\\\\(-5_{x_{1}},-6_{y_{1}})\\\\y-(-6)=2(x-(-5))\\\\y+6=2(x+5)[/tex]
Solve for y. Expand the right sie using the distributive property:
[tex]y+6=2(x)+2(5)\\\\y+6=2x+10[/tex]
Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:
[tex]y+6-6=2x+10-6\\\\y=2x+4[/tex]
OR
Slope-intercept form:
[tex]y=mx+b[/tex]
Where:
[tex]m[/tex] is the slope[tex]b[/tex] is the y-intercept[tex]x[/tex] and [tex]y[/tex] are corresponding coordinate points [tex](x,y)[/tex]Insert the given values:
[tex]m=2\\\\(-5_{x},-6_{y})\\\\-6=2(-5)+b[/tex]
Simplify the multiplication:
[tex]-6=-10+b[/tex]
Solve for b. Add 10 to both sides, canceling out the 10 on the right:
[tex]-6+10=-10+10+b\\\\4=b[/tex]
The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:
[tex]y=2x+4[/tex]
:Done
