40 percent of Marley's attempts were strikes, when  Marley rolled 28 strikes out of 70 attempts.

Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage. A % is a number that indicates how many out of 100 it is, and it can also be expressed as a decimal or a fraction. Put the percentage value in the numerator and 100 in the denominator to convert a percentage to a fraction.

Given,

28 strikes rolled by Marley

Total attempts = 70

For percentage,

28/ 70 × 100%

0.4 × 100%

40%

40 percent of Marley's attempts were strikes, when Marley rolled 28 strikes out of 70 attempts.

cx + cy = a² + b² is the next step to prove the theorem.

Given,

The given Pythagorean theorem was created by Todd.

With leg lengths a and b and a hypotenuse length of c, he drew right

ΔABC. The hypotenuse was then drawn with altitude C Z.

He finds that the equations c/a=a/x and c/b=b/y. He then discovers that c x=a² and c y=b².

We have to find the next step to prove the theorem;

Here,

The next step is to add cx and cy

That is,

cx + cy = a² + b²

Then,

c(x + y) =  a² + b²

c² =  a² + b²

The time the Road Runner been running is 7.3 minutes

From the question, we have the following parameters that can be used in our computation:

Roadrunner speed = 72mph

Time for repair = 15 minutes

Speed = 220mph

Represent the time the Road Runner been running with x

The speed is calculated using

Speed = Distance/Time

So, we have the following representations

Roadrunner speed = Distance/Time

Wile Coyote speed = Distance/Time

This gives

72 = Distance/(15 + x) -- for the roadrunner

220 = Distance/x for the Wile Coyote

So, we have

Distance = 72(15 + x)

Distance = 220x

Substitute the known values in the above equation, so, we have the following representation

220x = 72(15 + x)

Open the brackets

220x = 1080 + 72x

Evaluate the like terms

148x = 1080

So, we have

x = 7.3

Answer:

x = 56

y = 124

z = 56

Step-by-step explanation:

The 124° angle and y° are vertical angles. vertical angles are congruent. they have equal measures.

y = 124

Angles 124° and x° form a linear pair. Angles in a linear pair are supplementary. Their measures add to 180°.

124 + x = 180

x = 180 - 24

x = 56

Angles x° and z° are vertical angles.

z = x = 56

Answer:

x = 56

y = 124

z = 56

The total surface area of the moon is A = 79,98,258[tex]miles^{2}[/tex]

or  A =  2.07153931 × [tex]10^{13} m^{2}[/tex]

as per given in the question,

the radius of the moon ( r) is 798 miles

to find the area of the total surface area of the cylinder

Area (A) = [tex]4\pi r^{2}[/tex]  where r is radius of the sphere,

by substituting the radius in total surface area formula area,

A = [tex]4\pi (798) ^{2}[/tex]

                                    ( let [tex]\pi =3.14[/tex])

Answer: I believe it would be 55 but It would help if it says what kind of triangle it is.

Step-by-step explanation:

Answer:

The answer is 91°

Step-by-step explanation:

In any triangle, the sum of all angles is equal to 180°

So,

35° + 54° + x = 180°

x = 180 - 89

x = 91°

Thus, The third angle is 91°

The image of y which is g(x) is 3x² + 60x + 82.

Suppose we have a function f(x).

f(x) ± d = Vertical upshift/downshift by d units (x, y ±d).

f(x ± c) = Horizontal left/right shift by c units (x - + c, y).

(a)f(x) = Vertical stretch for a > 0, vertical shrink a < 0. (x, ay).

f(bx) = Horizonatal compression b > 0, horizontal stretch for b < 0. (bx , y).

f(-x) = Reflection over y axis, (-x, y).

-f(x) = Reflection over x-axis, (x, -y).

Given, y = 3x² - 24x + 2.

Now, g(x) is an image of y after a translation left 5 units and up 5 units.

∴ g(x) =  3(x + 5)² + 2 + 5.

g(x) = 3(x² + 20x + 25) + 7.

g(x) = 3x² + 60x + 75 + 7.

g(x) = 3x² + 60x + 82.

Answer:

We can use the point-slope formula to find the equation of the tangent line. The point-slope formula is given by:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line, and m is the slope of the line. To find the equation of the tangent line, we need to find the slope of the line and a point on the line.

To find the slope of the line, we can use the definition of derivative. The derivative of a function f(x) at a point x0 is defined as:

f'(x0) = lim(h->0) (f(x0 + h) - f(x0))/h

In our case, the function f(x) is given by f(x) = x^2 - 5, and the point x0 is -2, so we have:

f'(-2) = lim(h->0) (f(-2 + h) - f(-2))/h

Substituting the value of the function f(x) = x^2 - 5, we get:

f'(-2) = lim(h->0) (((-2 + h)^2 - 5) - ((-2)^2 - 5))/h

Simplifying the expression, we get:

f'(-2) = lim(h->0) (h^2 - 4h)/h

Since the limit is defined as h approaches 0, we can drop the h from the denominator since it will become insignificant in the limit:

f'(-2) = lim(h->0) (h^2 - 4h)

Now we can evaluate the limit as h approaches 0:

f'(-2) = lim(h->0) h^2 - 4h

In the limit, h^2 becomes 0, so we are left with:

f'(-2) = lim(h->0) - 4h

Since the limit is defined as h approaches 0, the value of the limit is simply -4 times 0, which is 0. Therefore, the slope of the tangent line is 0.

Now that we know the slope of the tangent line, we need to find a point on the line. We are told that the line passes through the point (-2, f(-2)) on the function f(x) = x^2 - 5. Substituting the value of the function, we get:

(-2, f(-2)) = (-2, (-2)^2 - 5) = (-2, -9)

So the point on the line is (-2, -9).

We now have the slope and a point on the line, so we can use the point-slope formula to find the equation of the line. Substituting the values into the point-slope formula, we get:

y - (-9) = 0(x - (-2))

Simplifying, we get:

y = -9

Therefore, the equation of the tangent line that passes through the point (-2, -9) with a slope of 0 is given by y = -9.

The probability that the next customer pays with a debit card or a credit card will be 0.28.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

Step-by-step explanation:

its B because the price goes up $40 every 500 KW's so

40 divided by 500 = 0.08

The expression used to calculate Naomi's electricity cost after using x kilowatt hours is 0.08x+20. Therefore, option B is the correct answer.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

From the graph we have, (500, 60), (1000, 100), (1500, 140) and (2000, 180).

We know that, slope of a line is Slope=(y2-y1)/(x2-x1)

= (100-60)/500

= 40/500

= 0.08

Substitute m=0.08 and (x, y)=(500, 60) in y=mx+c, we get

60=0.08(500)+c

60=40+c

c=20

Substitute m=0.08 and c=20 in y=mx+c, we get

y=0.08x+20

The expression used to calculate Naomi's electricity cost after using x kilowatt hours is 0.08x+20. Therefore, option B is the correct answer.

The vertex and range of y = |x + 1| + 3 will be (−1, 3); 3 ≤ y < ∞ respectively.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

You may get the vertex of y = |x + 1| + 3 as follows.

Where the absolute values are zeros are the vertex points of the absolute value function.

|x + 1| = 0

x + 1 = 0

x = -1

Substitute the value into an original function,

y = |-1 + 1| + 3

y= 0 + 3

y = 3

As a result, the vertex is at (-1, 3)

Remember that the domain is specified in the range of (-∞, ∞) while determining the range.

Given that |x + 1| ≥ 0 , (absolute value is always 0 or positive)

The result of adding 3 to the inequality's two sides is

|x + 1| + 3 ≥ 3

But since |x+1| + 3 is identical to f(x) = y, we have y = f(x) 3, which means that the range is specified for all values larger than 3.

So the range is 3 ≤ y < ∞

Thus,the vertex and range of y = |x + 1| + 3 will be (−1, 3); 3 ≤ y < ∞ respectively.
