The required percentage that Cortney got correct on the test will be; 85.33%.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
We have been given that Cortney got 64 out of 75 correct on a test.
We Need to determine the best estimate of the percentage Courtney got correct.
Here,
The Total question = 75
The correct question = 64
Then Percentage = 64 / 75 × 100
Percentage = 85.33%
Thus, the required percentage that Cortney got correct on the test will be; 85.33%.

Answer:
8) Onaje is correct
9a) answers could be: 3(6y) or 4y + 6y + 8y or 2(2y + 3y + 4y)
b) all answers simplify to be 18y
Step-by-step explanation:
Paula is not correct because 16t + 9t ≠ 16 + 9 + 2t
16t + 9t only equals 25t
Answer:
8. Onaje's expression is correct.
Step-by-step explanation:
The price, t, of the medium T-shirts can be represented as 16t, or 16 × t.
The price, t, of the large T-shirts can be represented as 9t, or 9 × t.
16t + 9t = (16 + 9) × t = 25t
Answer:
9. Part a: The expression could be 9y - 3y + 12y.
9. Part b: 9y - 3y = 6y
6y + 12y = 18y

A regular octagonal pyramid. Each side of the base is 6 cm long. it has a height of 10cm. Find the surface area of the pyramid
9514 1404 393
Answer:
470.16 cm²
Step-by-step explanation:
The apothem of the base is used for two purposes: to find the area of the base, and to find the slant height of each face.
The apothem of the base for side length s is ...
s/2 = a·tan(π/8)
a = s/(2·tan(π/8)) ≈ 7.24 cm
The slant height of a triangular face is found using the Pythagorean theorem. The apothem of the base and the height are legs of the right triangle whose hypotenuse is the slant height. For slant height x, we have ...
x² = 10² + a² = 100 +52.46
x ≈ √152.46 ≈ 12.35
__
The area of the 8 triangular faces will be ...
A = 1/2Px . . . . where P is the perimeter of the pyramid
The area of the base will be ...
A = 1/2Pa
So, the total surface area is ...
A = 1/2P(a + x) = (1/2)(8)(6 cm)(7.24 +12.35 cm) ≈ 470.16 cm²
The answer is 470.16 cm²

Which statements are true?
Select each correct answer.
Since −6 is 6 units to the left of 0, |−6|=6 .
The absolute value of −6 is negative.
The absolute value of −6 is less than the absolute value of 6.
−6 is closer to zero on the number line than −7 , so |−6|<|−7| .
Answer:
The first one and the last one are true (Since −6 is 6 units to the left of 0, |−6|=6 and −6 is closer to zero on the number line than −7, so |−6|<|−7|.)
Step-by-step explanation:
Absolute value is the distance to zero, and it is always positive. That means the positive and negative versions of a number have the same absolute value. That means the first one is true, and the second and third ones are false. For the last one, -6 is closer to zero, so that means it would be true (The absolute value of -6 is 6, and the absolute value of -7 is 7).
Find the slope and the -intercept of the line. y=-1/5x+7 plz i need help

Identify the x- and y-intercepts of the equation
4x - y = 8
[tex]\boxed{\boxed{\pink{\sf \leadsto The \ x - intercept \ is \ (2,0) \ \& \ the \ y \ intercept \ is \ (-8,0) }}}[/tex]
Step-by-step explanation:A linear equation is given to us and we are required to find x and y Intercepts to it. So the given linear equation to us is ,
[tex]\bf \implies 4x - y = 8 \\\\\bf\implies \dfrac{1}{8} \bigg( 4x -y\bigg) =\frac{1}{8}\times 8 \\\\\bf\implies \dfrac{4x}{8}-\dfrac{y}{8} = \dfrac{8}{8} \\\\\bf\implies \dfrac{x}{2}-\dfrac{y}{8}=1 \\\\\bf\implies\boxed{\red{\bf \dfrac{x}{2}+\dfrac{y}{-8}=1 }}[/tex]
Hence on comparing to standard form we get
x intercept as (2 , 0 )y intercept as (0,-8) Hence the x - intercept is ( 2 , 0 ) and the y - intercept is ( 0 , -8 ) .Answer:
x = (2,0)
y = (0,-8)
Step-by-step explanation:
Remember than an intercept always has the other number as 0.
Let's put this in standard form of a linear equation, or y = mx + b
4x - y = 8
-y = -4x + 8
y = 4x - 8
"b" is the y intercept. The y intercept is -8, or (0,-8)
Now, to find the x intercept, all we have to do is substitute 0 for y.
0 = 4x -8
8 = 4x
2 = x
The x intercept is 2, or (2,0)
