The required percentage that Cortney got correct on the test will be; 85.33%.

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:

8×8×8 =512

Step-by-step explanation:

prove me wrong

Answer:

512 cm

Step-by-step explanation:

the formula to find volume is length × width + height (L×W×H) and since it is a cube all of the sides are equal so simply multiple 8 × 8 × 8 to get 512

Answer:

n=7

Step-by-step explanation:

6(n-3)-2n=10

Distributive Property

6n-18-2n=10

Combine like terms

4n-18=10

Addition property of equality with -18; add -18 to both sides

4n=28

Division property of equality; divide 4 from both sides

n=7

[tex]1\frac{1}{9}[/tex]

Answer:

105

Step-by-step explanation:

all angles inside a triangle add up to equal 180, the inside angle at R is 75 degrees, the TP line is obviously a 180 degree angle, because it's just a straight line, so you subtract 75 from 180 to get 105

the answer is the last one or D

Step-by-step explanation:

Answer:

x=3

y=1

Step-by-step explanation:

We know that y is basically two less than x, so we can plug that into the second equation:

x+ (x-2) = 4

We can now simplify:

2x-2=4

2x=6

x=3

After finding x we can now find y with any equation (both work):

y= 3-2

y=1

Hope this helped!

Answer:

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Point Form:

(  3 , 1 )

Answer:

y = - x + 4

Step-by-step explanation:

The first step is to find the slope-intercept form, which is:

y=x-6.

Then, y=x+6

y=-x+4 should be the answer since it passes through the point (-1, 5)

Answer:

y=x+6

Answer:

[tex]\huge\boxed{a =\frac{s-t}{m-r}}[/tex]

Step-by-step explanation:

In order to convert an equation to solve for another variable, we need to algebraically manipulate the problem until we're left with a isolated on one side.

Step 1: Subtract [tex]t[/tex] from both sides

Step 2: Divide both sides by [tex]m- r[/tex]

Hope this helped!

Answer:

i think its 75

Step-by-step explanation:

bend your head to the right and compare to a 90 degree square

it's acute

Answer: 75°

Step-by-step explanation:

m∠BGC + m∠AGB + m∠AGE = 180°

m∠BGC + 31 + 74 = 180°

m∠BGC + 105 = 180°

m∠BGC = 75°

Answer:

-95/87

Step-by-step explanation:

Formula to find slope: (y2-y1) / (x2-x1)

In this problem y2 is -3 and y1 is 92. x2 is 97 and x1 is 10.

We substitute these numbers into the equation.

(-3-92) / (97-10)

Then we simplify this by subtracting.

-95/87 is our final answer.

Answer:

[tex]\dfrac{6x+2}5}[/tex]

Step-by-step explanation:

The given expression is :

[tex]\dfrac{3x}{5}+\dfrac{2}{5}+\dfrac{3x}{5}[/tex]

We need to write the equivalent expression for the above expression.

Taking like terms together,

[tex]=(\dfrac{3x}{5}+\dfrac{3x}{5})+\dfrac{2}{5}\\\\=\dfrac{3x+3x}{5}+\dfrac{2}{5}\\\\=\dfrac{6x}{5}+\dfrac{2}{5}\\\\=\dfrac{6x+2}5}[/tex]

So, the equivalent expression is [tex]\dfrac{6x+2}5}[/tex].

Answer:

b = 5.2

c = 3.5

Step-by-step explanation:

By 45°- 45° - 90° triangle theorem:

[tex]c = \frac{1}{ \sqrt{2} } \times 5 \\ \\ c = \frac{1}{ 2} \times 5 \sqrt{2} \\ \\ c = 2.5 \times 1.414\\ \\ c = 3.535 \\ \\ c \approx \: 3.5[/tex]

By 30°- 60° - 90° triangle theorem:

[tex] b = \frac{ \sqrt{3} }{2} \times (2 \times 3) \\ \\ b = 3 \sqrt{3} \\ \\ b = 3 \times 1.732 \\ \\ b = 5.196 \\ \\ b \approx 5.2[/tex]

Answer:

7.5
