Milo recorded the number of hours he worked and the total amount he earned, including tips. Let h be the number of hours he worked, and let y be the total amount he earned, including tips. The equation of a line of best fit of his data is y = 12.5h +3.85. Based on the equation of the line of best fit, how much money should Milo expect to earn if he works a 5-hour shift?
Answer:
$66.35
Step-by-step explanation:
To find this answer with y=mx+b, we should first explain what it is. Y is our output or answer. M is our variable and x is the slope of our variable or how often it occurs. B, is our y intercept, our initial starting amount. Knowing this, we must figure out y. To do this we must multiply his hourly wage by the hours he works which is $12.50x5. This will get us $62.50. Now that we know how much he makes hourly, we add his initial wage of $3.85 to get us $66.35
This means he will make $66.35 if he works a full 5 hour shift.

There is a triangle with sides measuring 30in, 30in and 25in. Is this a right triangle? Why or why not?
Answer:
No. In order to be a right triangle, the lengths of the 2 smaller sides must equal the length of the longest side.
In other words, these 3 sides must work with the Pythagorean theorem.
A^2 + B^2 = C^2
25^2 + 30^2 is NOT 30^2
This is a triangle, just not a right triangle.

24 – (-14) = ______
-9 · -5 = ______
31 + x = 15 x = ______
2 x + 5 = 15 x = ______
Step-by-step explanation: (Answers in bold )
24-(-14) using the keep change change rule you get 24 +14 = 38
-9*-5 =45 (negative times a negative = a positive )
31+x=15x subtract x from both sides
31=14x divide by 14
31/16 ---or---> 2.21
2x+5= 15x subtract 2x from both sides
5=13x divide by 13

In a quadratic function, recall that the discriminant D = b2 - 4ac. For which function is it true that a < 0 and D = 0?
Answer:
If D = 0, then the quadratic equation has 1 solution x = − b/2a
Step-by-step explanation:
If we have a quadratic equation x² +3x-4= 0
Then the corresponding values of a= 1, b=3, c= -4
Finding the discriminant gives
D= b2 - 4ac.
D= 3²- 4(1) (-4)
D= 9 + 16
D= 25
Here a> 0
But if a< 0 e.g a= -1
D= b2 - 4ac.
D= 3²- 4(-1) (-4)
D= 9 - 16
D= -7
Here a < 0 so we get the answer -7 < 0
D= b2 - 4ac.
D= 4²- 4(-1) (-4)
D= 16 - 16
D= 0
Here a< 0 and b= - c so that D= 0
When D < 0 roots do not exist.
If D = 0, then the quadratic equation has 1 solution x = − b/2a
This can be found out by using the quadratic formula
x= -b±√b²- 4ac/ 2a
But D= 0
x= -b±0/ 2a
x= -b/2a

What is the perimeter of the rectangle?
Answer:
10 feet
Step-by-step explanation:
Perimeter of rectangle = 2l+2b
Area of the rectangle = l x b
Area of the rectangle = 4 square feet
possible factors of 4 = 2x2/4x1
So sides of the rectangle are 4 & 1 as 2&2 would make it a square
So perimeter= 2x4+2x1
= 8+2
= 10 feet

A rectangle has a perimeter of 72 millimeters and a width of 8 millimeters. What is the length of this rectangle?
Answer:
28
Step-by-step explanation:
Since the perimeter is the width + width + length + length, we know that there 2 of the 8 millimeter width in the perimeter. So multiply 8 by 2, which is 16. So 16 of the 72 represents both widths. So subtract 16 from 72. You're left with 56, which represents 2 of the length. So divide 56 by 2, and you get one of the length, which is 28.
Answer:
28 ^^
