In the problem, 'X' denotes the cost to rent each pair of skates. Setting up and solving the equation, 9 + 7X = 30, we find 'X', the cost per pair, is $3.

In this problem, 'X' represents the cost to rent each pair of skates. The problem refers to a situation where a skating rink charges $9 for a group rate and an additional fee for every pair of skates rented. According to the provided information, a family who rents 7 pairs of skates pays a total of $30. We can set up an equation to solve for 'X.'

The equation is 9 + 7X = 30, where X is the cost per pair of skates.

To solve this equation, you have to subtract 9 from both sides, getting 7X = 21. Afterward, you divide both sides by 7, and you get X = 3. Therefore, 'X' corresponds to $3, the cost per pair of skates.

Answer:

C)

Step-by-step explanation:

100/2 = 50 goes in the fifth position of the list

50/2 = 25 goes in the sixth position of the list

And the complete pattern is: 800, 400, 200, 100, 50, 25

Then, every number in the pattern will have a 0 or a 5 in its ones place.

An expression that has the same value as (-14) - 8 is (-14) + (-8), both of which equal -22.

The question is about finding an expression that is equivalent to (-14) - 8. When we subtract a positive number from a negative number, we move further to the left on the number line, making the number more negative. Therefore, (-14) - 8 is the same as adding the opposite of 8, which is -8, to -14, giving us -22. Another way to see it is moving 8 units to the left from -14 on a number line.

Thus, an equivalent expression might be the subtraction of the negative of 8, which is (-14) + (-8). We add the two negative numbers together following the rule that adding two negative numbers results in a negative sum. In this case, (-14) + (-8) is also -22.

Answer: The city will need 33 trees.

Step-by-step explanation:

Hi, to answer this question we simply have to divide the length of the path (5 1/2 miles) distance between trees (1/6).

Mathematically speaking:

5 1/2 ÷ 1/6 = (5x2+1) /2 ÷1/6 = 11/2 ÷1/6 = (11x6) /(2x1) = 66/2 =33 trees

The city will need 33 trees.

Feel free to ask for more if needed or if you did not understand something.  

Final answer:

To determine the number of trees needed for a roadway with trees spaced every 1/6 mile along a 5 1/2-mile path, divide the total distance by the spacing distance to find 33 trees required.

Explanation:

Roadway:

To find the number of trees needed, we first calculate the distance between trees: 1/6 mile. The total length of the road is 5 1/2 miles, so we divide the total length by the distance between trees to find the number of trees needed:
5 1/2 miles ÷ 1/6 mile = 5.5 ÷ 1/6 = 5.5 * 6 = 33 trees

Answer:

The ball will return to the ground after 1.25 seconds

Step-by-step explanation:

Given

f(t) = -16t² + 20t

Required

After what time (in seconds) does the ball return to the ground?

Function f(t) is a function of time and it represents the displacement of the ball.

For the ball to return to the ground, it means the displacement is 0.

So, we have f(t) = 0.

Substitute 0 for f(t) in the above, we have

0 = -16t² + 20t ---- Factorize

0 = -4t(4t - 5) ---- Reorder

-4t(4t - 5) = 0

This above expression can be splitted to;

-4t = 0 or 4t - 5 = 0

For -4t = 0,

divide through by -4

This will give t = 0

For 4t - 5 = 0,

Collect like terms

4t = 5 + 0

4t = 5

Divide through by 4

t = 5/4

t = 1.25

So, we have that

t = 0 or t = 1.25

But t can't be 0 because the ball has already traveled some distance.

So, t = 1.25

Hence, the ball will return to the ground after 1.25 seconds

Given the value of rectangular prism are 9 and 10 in respectively.

Area of rectangular prism = 2(lw+ wh+ lh)

2(d10 + 10×9+d9) = 2(19d+90) = 38d+180 = 674

38d = 674-180 = 494

d = 494/38 = 13in

The probability of spinning 'green' on the first spinner and 'blue' on the second spinner can be calculated by multiplying the individual probabilities assuming that they are independent events.

The probability of getting 'green' on the first spinner and 'blue' on the second spinner can be calculated by multiplying the individual probabilities if the two events are independent. If the first spinner has 'g' green out of 't' total possible outcomes and the second spinner has 'b' blue out of 's' total outcomes, the first probability would be 'g/t' and the second one 'b/s'. Hence, the probability of spinning 'green' on the first and 'blue' on the second would be (g/t) * (b/s).

For instance, if the first spinner has 2 green areas out of 10 total (2/10=0.2) and the second spinner has 3 blue areas out of 10 (3/10=0.3), then the probability of spinning 'green' first and 'blue' second would be 0.2*0.3=0.06 or 6%. Remember that the aforementioned explanation assumes that the outcomes from the two spinners are independent, that is, the result from the first does not affect the result from the second.

The probability of spinning green on the first spinner and blue on the second spinner is 1/9.

To calculate the probability of independent events, we need to multiply the probabilities of each event occurring separately.

Assume the first spinner has equal sections for each color: red, blue, and green.

Thus, the probability of spinning green is 1/3.

Similarly, assume the second spinner has equal sections for each color: red, blue, and green.

Thus, the probability of spinning blue is 1/3.

Since the spins are independent events, the overall probability is calculated by multiplying these probabilities:

P(Green on first) * P(Blue on second) = 1/3 * 1/3 = 1/9

The equation for the given line in slope-intercept form is y = (-3/5)x - 1.

Option D is the correct answer.

We have,

The slope-intercept form of a linear equation,

y = mx + b

where m represents the slope of the line and b represents the y-intercept.

The slope (m) of the line using the two given points (0, -1) and (5, -4):

m = (y₂ - y₁) / (x₂ - x₁)

m = (-4 - (-1)) / (5 - 0)

m = (-4 + 1) / 5

m = -3 / 5

Substitute it into the slope-intercept form, along with one of the given points (0, -1), to find the value of b:

-1 = (-3/5)(0) + b

-1 = b

The y-intercept (b) is -1.

The equation of the line using the slope-intercept form:

y = (-3/5)x - 1

Thus,

The equation for the given line in slope-intercept form is y = (-3/5)x - 1.

Answer:

The volume of the square pyramid is 766.3 in³ approximately.

Step-by-step explanation:

To find the volume of the square pyramid whose perimeter of the base is 44 in and a height of 19 in, we will follow the steps below:

Write down the formula for calculating volume of the square pyramid

v=A(h/3)

where v is the volume, A is the area of the base and h is the height.

From the question given, the perimeter of the base is 44.

If the perimeter of the base is 44, then we can say;

4l = 44

Dividing both-side by 4

l = 11

The length of the base = 11

Area of the base = l² =11² = 121 in²

Als from the question given, height is 19 in.

we can now proceed to plug in our values into the formula

v=A(h/3)

v = 121 (19/3)

v≈766.3 in³ to the nearest tenth.

Therefore, the volume of the square pyramid is 766.3 in³ approximately.

Step-by-step explanation:

The function is g(x) = 4^((1/2)*x)

For A, the value is -2.  Plug this into the equation.

g(-2) = 4^((1/2)*-2)

g(-2) = 4^(-1)

g(-2) = 1/4

For B, the value is 0.  Plug it into the equaiton.

g(0) = 4^((1/2)*0)

g(0) = 4^(0)

g(0) = 1

For C, the value is 2.  Plug it into the equation.

g(2) = 4^((1/2)*2)

g(2) = 4^1

g(2) = 4
