Answer:
75
Step-by-step explanation:
Scores for his first tests were 65, 67, 69.
Rate of change: +2
y=2x+63; 63 is the 0th test he took, his first test was 65, so 65-2=63. 2x is the rate of change, his tests scores increase by 2 each time.
x=6, 6th test score
y=2(6)+63
y=12+63
y=75
So, on his 6th test he will get a score of 75

When a farmer harvests apples he expects 6% of the apples to be rotten how many apples would the farmer expect to be rotting when harvesting apples
The question is incomplete had the number of harvested apples isn't given.
Answer:
0.06n
Step-by-step explanation:
When a farmer harvests apples he expects 6% of the apples to be rotten how many apples would the farmer expect to be rotting when harvesting apples
The expected percentage of rotten apples when harvesting = 6%
The expected number of rotten apples can be obtained by taking the product of the expected percentage and the number of apples to be harvested.
Since the number of harvested apples isn't given,
Let the number of harvested apples = n
Therefore, the expected number of rotten apples will be :
6% * n
0.06n
Note : you can easily substitute the actual number of harvested apples for n in the equto get the actual answer

Answer: E
Step-by-step explanation:
You have to add 2 to the other side and shade to the left because it’s less than 18.
Answer:
Letter E
Step-by-step explanation:
To solve this, all you need to do is add two to both sides to isolate the x, and that will result in x ≤ 18. In a number line, it is a closed circle (because it has the line below the sign), and it points to the left because it is less than or equal to.

Which of the following polynomials does not have real roots?
A. x2 + x-2
B. 12x2 - 17x- 7
C. x + 5x + 6
D. x2 + x + 2
Which set of side lengths or angle measures can be used to construct a triangle A. 50 inches, 90 inches, 35 inches B. 60 inches, 25 inches, 95 Inches C. 45,45,80 D. 60, 45,75
Answer:
D. 60, 45,75
Step-by-step explanation:
For options C and D
For a triangle the sum of the angles must always be equal to 180 degrees
So 180 ≠45+45+80
and
60 +45+ 75= 180
For option A and B
The length of the longer side is equal to the square root of the sum of squares of the other two sides in a triangle.
According to Pythagorus theorem
hypotenuse²= base² + perpendicular²
c²= a²+ b²
90²= 50² + 35²
8100= 2500+1225
8100≠3725
95²= 60²+ 25²
9025= 3600+ 625
9025≠4225
Therefore only D is the correct option

Mackenzie made 38 of 50 free throws. What is the
experimental probability that Mackenzie will NOT
make the next free throw she attempts?
A- 6/25
B- 12/25
C- 19/25
D- 21/25
A I believe because Against the odds of 38/50 would be 12/50 that is not an option so split in half this would be A cause its an equivalent fraction
Fuel for an outboard motor has a gas to oil ratio of 50:1. How much oil is needed for 25.5L of gas?
Answer:
The oil needed is 0.51.
Step-by-step explanation:
Since you know that the gas to oil ratio is 50:1 and you have to find the oil needed for 25.5L of gas, you can write the numbers in the ratio as a fraction and let's consider that x is the amount of oil needed:
[tex]\frac{50}{1} = \frac{25.5}{x}[/tex]
Now, you have to solve this using cross multiplication:
50*x=25.5*1
50x=25.5
Finally, your have to isolate the variable x:
x=25.5/50
x=0.51
According to this, the answer is that the oil needed is 0.51.

Step-by-step explanation:
Answer:
∠A= 111.75°
Step-by-step explanation:
Please see the attached picture.
∠B +∠C= 180° (adj ∠s on a str. line)
(x +35)° +∠C= 180°
∠C= 180° -(x +35)°
∠C= 145° -x°
∠A= ∠C (corr. ∠s)
∠A= 145° -x°
Given that ∠A is (3x +12)°, equate this expression to the expression we found.
145° -x°= 3x° +12°
3x° +x°= 145° -12°
4x°= 133°
x°= 133° ÷4 (÷4 on both sides)
x°= 33.25°
Substitute the value of x back into the expression for ∠A:
∴∠A= 3(33.25°) +12°
∠A= 111.75°

When three squares are joined at their vertices to form a right triangle, the combined area of the two smaller squares is the same as the area of the largest square. Which three squares will support this statement?
Answer:
J
Step-by-step explanation:
Area of a square = L x W
F:
(5 x 5) + (4 x 4) = 81
25 + 16 = 81
41 = 81 INCORRECT =( X
H:
64 + (5 x 5) = (13 x 13)
64 + 25 = 169
89 = 169 INCORRECT =( X
G:
(6 x 6) + (5 x 5) = (7 x 7)
36 + 25 = 49
61 = 49 INCORRECT =( X
J:
144 + (5 x 5) = 169
144 + 25 = 169
169 = 169 CORRECT =)

Answer:

Step-by-step explanation:
When you see things that move at a non linear rate, it means that it is not a straight line. Automatically, you can eliminate A and D because the lines there between those numbers are straight. Now we have two non linear lines left and there is only one that is decreasing (going down and it is the line between -2 and 0.
