The height of the cylinder whose surface area is given would be = 85 yards.

How to calculate the height of a cylinder?

The cylinder is a type of shape that has three sides which consists of two opposite circles that are joined by a curved surface.

To calculate the height of a cylinder, the formula that should be used is given as follows:

Surface area of cylinder = 2πrh + 2πr²

radius = 29 yards

surface area = 20,761.68 square yards

height = ?

That is ;

20,761.68 = 2×3.14× 29×h + 2×3.14× 29×29

20,761.68 =182.12h + 5281.48

182.12h = 20,761.68-5281.48

182.12h = 15480.2

h = 15480.2/182.12

From the line of scrimmage, the quarterback gets the ball and backs up 5 yards so he can see the rest of the field. Unfortunately, he has nowhere to go with the ball and falls back an additional 6 yards before being tackled. Which of the following numbers represents the yardage for that play?-1-11-5-6

Answers

We know that

• The quarterback backs yo 5 yards (negative number).

• He falls back another 6 yards more (negative number).

To know the total number of yards the quarterback felt back, we just need to sum these negative numbers.

The value of angle BAC is  43.5⁰.

The value of arc angle BC is  96⁰.

The value of angle 1 is 10⁰.

What is the value of angle BAC?

The value of angle BAC is calculated as follows;

m∠ BAC = ¹/₂ (BMC) (angle at center is half of the angle at circumference)

m∠ BAC = ¹/₂ ( 87 )

m∠ BAC = 43.5⁰

The value of arc angle BC is calculated by applying intersecting chord theorem as follows;

arc BC = 2 x m∠BAC (interior intersecting secants)

arc BC = 2 x 48⁰

arc BC = 96⁰

The value of angle 1 is calculated as follows;

m∠1 = ¹/₂ ( 85⁰ - (360 - (140 + 85 + 70) )

m∠1 = ¹/₂ (85 - 65 )

m∠1 = ¹/₂ (20)

m∠1 = 10⁰

The functions f(x) and g(x) are equal for the x = 2/3

What is a function?

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given that, are two functions, f(x) = -3x + 4 and g(x) = 2, we need to find the value of x for which both are equal,

So,  

For f(x) = g(x) we should equate the two functions to get the value of x.

f(x) = g(x)

-3x + 4 =  2

-3x + 4 - 4 = 2 - 4

-3x = -2

Dividing by -3 on both sides;

(-3x)/-3 = (-2)/-3

x = 2/3

Hence, the  functions f(x) and g(x) are equal for the x = 2/3

2 Question 3 3.1 The layout plan of the copy room at Hills Secondary is given below.
3.1 justify a reason whether or not copier is suitably placed in room (3) ​

Answers

Based on these considerations, it is necessary to assess the specific layout plan and the surrounding environment to determine whether the copier is suitably placed in room (3) at Hills Secondary.

To determine whether the copier is suitably placed in room (3) at Hills Secondary, we need to consider factors such as accessibility, noise, and convenience.

Firstly, we need to evaluate the accessibility of the copier in room (3). Is it easily accessible for all students and staff who need to use it? If the copier is located in a central position within the school or close to high-traffic areas, it would be considered suitable.

However, if it is tucked away in a corner or not easily visible, it may cause inconvenience and hinder access for users.

Secondly, we should consider noise levels. Copiers can be noisy machines, and if room (3) is located near classrooms or areas where students require a quiet environment, it may not be an ideal placement. Noise disturbances could disrupt learning activities and cause distractions.

Lastly, convenience plays an important role. Room (3) should be spacious enough to accommodate the copier and allow users to operate it comfortably. If the room is cramped or lacks proper ventilation, it may cause inconvenience for users and impact the overall workflow.

\( \sf \longrightarrow \: 5 \bigg( \: \frac{n}{1} - \frac{1}{10} \bigg) = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: 5 \bigg( \: \frac{10 \times n - 1 \times 1}{1 \times 10} \bigg) = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: 5 \bigg( \: \frac{10n - 1}{ 10} \bigg) = \frac{1}{2} \\ \)

To solve the equation \(\sf 5(n - \frac{1}{10}) = \frac{1}{2} \\\) for \(\sf n \\\), we can follow these steps:

Step 1: Distribute the 5 on the left side:

\(\sf 5n - \frac{1}{2} = \frac{1}{2} \\\)

Step 2: Add \(\sf \frac{1}{2} \\\) to both sides of the equation:

\(\sf 5n = \frac{1}{2} + \frac{1}{2} \\\)

\(\sf 5n = 1 \\\)

Step 3: Divide both sides of the equation by 5 to isolate \(\sf n \\\):

\(\sf \frac{5n}{5} = \frac{1}{5} \\\)

\(\sf n = \frac{1}{5} \\\)

Therefore, the solution to the equation \(\sf 5(n - \frac{1}{10})\ = \frac{1}{2} \\\) is \(\sf n = \frac{1}{5} \\\), which corresponds to option (d).

Pablo used a total of 5 3/4 gallons of gas while driving his car. Each hour he was driving, he used 5/6 gallons of gas. What was the total number of hours he was driving? Write your ans

Answers

Let x be the number of hours Pablo was driving.

We know that he used 5/6 gallons of gas per hour of driving.

So, the total amount of gas he used is 5/6 * x.

We also know that he used a total of 5 3/4 gallons of gas.

So, we can set up the equation:

5/6 * x = 5 3/4

To solve for x, we can first convert 5 3/4 to an improper fraction:

5 3/4 = 23/4

Then, we can multiply both sides of the equation by the reciprocal of 5/6:

x = (5 3/4) / (5/6)

x = (23/4) / (5/6)

x = (23/4) * (6/5)

x = 27.6/4

x = 6.9

Therefore, Pablo was driving for a total of 6.9 hours.

Step-by-step explanation:

when looking for a point that is 7 points away, we are looking for a difference of 7 in either the x-value or the y-value.

[remember: a point is written as (x, y) ]

We know that the x-value is -7, meaning that it is 7 units under the x-axis (meaning that it is 7 units away)

We know that our point, (2 , -7) has the same y-value as (-5, -7), so we are looking for a change in x. The difference (which is the change) between:

-5 and 2 is 7

(2 - (-5) = 2 + 5 = 7)

so, both the x-axis and the point (-5, -7) are 7 units away from (2, -7)

(the other point (-7, 7) is not near (2 , -7) at all--they have a larger difference on both the y-values, the x-values, and the length of if you made a diagonal line)

The graph of g(x) = 4x, is the translation of f(x) by subtracting 3.5 units, 2 of 3.

What is a graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The cost can be modeled by the function f(x)=4x+3.5, where x represents the number of games bowled.

As per the given question, the required solution would be as:

g(x) = 4x , is the translation of f(x) by subtracting 3.5 units, 2 of 3.

The graph of g(x) would be identical to the graph of f(x), but shifted 3.5 units downward, 3 of 3.

This is because the flat fee for the rental of bowling shoes is not present in the function g(x), so the y-intercept of the graph would be at (0,-3.5) instead of (0,0) in f(x) function.

The slope and the shape of the function will remain the same.
