b. Find the area of the football field when the width is 160 feet.
The area is
square feet

Answers

Answer 1

Answer:

a. area of the football field = 40ײ + 240x + 200 ft²

b. area = 57600  ft²

Step-by-step explanation:

The football field is rectangular in shape . Therefore, the area of the football field is the product of length and width.

length = 10x + 10

width = 4x + 20

area of the football field = (10x + 10)(4x + 20)

area of the football field = 40ײ + 200x + 40x + 200

area of the football field = 40ײ + 240x + 200

The standard form polynomial simply implies that the terms are ordered from the largest exponent to the smallest exponent. Therefore the standard form will be  

area of the football field = 40ײ + 240x + 200 ft²

b. area of the football field when width is 160 ft.

The width of the field = 4x + 20. Therefore

160 = 4x + 20

4x = 160 - 20

4x = 140

divide both sides by 4

x = 140/4

x = 35

area = length × width

area = (10x + 10) × 160

where

x = 35

area = (350 + 10) × 160

area = 360 × 160

area = 57600  ft²

Answer 2

a. area of the football field = 40ײ + 240x + 200 ft²

b. area = 57600  ft²

The calculation is as follows:

length = 10x + 10

width = 4x + 20

So,

area of the football field = (10x + 10)(4x + 20)

= 40ײ + 200x + 40x + 200

= 40ײ + 240x + 200

b. area of the football field when width is 160 ft.

The width of the field = 4x + 20.

So,

160 = 4x + 20

4x = 160 - 20

4x = 140

x = 35

area = length × width

= (10x + 10) × 160

= (350 + 10) × 160

= 360 × 160

= 57600  ft²

If G is the midpoint of
FH,
find FG.

Answers

Answer:

15

Step-by-step explanation:

15 is the answer because i looked it up

The required value of segment FG is 67 if G is the midpoint of FH.

What is a Line Segment?

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given below shows a line segment FH, where the length of line segment FHrefers to the distance between its endpoints, F and H.

Given that G is the midpoint of FH

FG = 14x + 25 and  GH= 73 - 2x,

To determine the value of FG

F______________G______________H

⇒ FH= FG+ GH

Since G is the midpoint of FH, SoFG = GH

⇒  FH = FG+ GH

⇒ FH = 2FG

⇒ FG = GH

Substitute the values of FG = 14x + 25 and  GH = 73 - 2x,

⇒ 14x + 25 = 73 - 2x

⇒ 14x + 2x = 73 - 25

⇒ 16x = 48

⇒ x = 48/16

⇒ x = 3

Substitute the value of x = 3 in FG,

⇒ FG = 14x + 25

⇒ FG = 14(3) +25

⇒ FG = 67

Hence, the required value of segment FG is 67 if G is the midpoint of FH.

Use substitution to solve the system of equation. 2x+2y=8 x+y=-2

Answers

Answer:

Step-by-step explanation:

find the value of y in the second equation

x + y = -2,

but y = -2-x as well

so take the value that we have found for (x) into the first equation

2x + 2(-2-x)= 8

-2x + -4-2x = 8

-4x-4=8

-4x = 12

x=-3,

now just substitute x value into either equation

x + y =-2

-3 + y = -2

y =1

The mean resting pulse rate for men is 72 beats per minute. A simple random sample of men who regularly work out at Mitch's Gym is obtained and their resting pulse rates (in beats per minute) are listed below. Use a 0.05 significance level to test the claim that these sample pulse rates come from a population with a mean less than 72 beats per minute. Assume that the standard deviation of the resting pulse rates of all men who work out at Mitch's Gym is known to be 2.6 beats per minute.

Answers

Answer:

We conclude that the mean resting pulse rate for men is 72 beats per minute.

Step-by-step explanation:

We are given that he mean resting pulse rate for men is 72 beats per minute. Assume that the standard deviation of the resting pulse rates of all men who work out at Mitch's Gym is known to be 2.6 beats per minute.

A simple random sample of men who regularly work out at Mitch's Gym is obtained and their resting pulse rates (in beats per minute) are listed below;

87, 89, 69, 63, 70, 65, 88, 84, 58, 53, 66, 70.

Let [tex]\mu[/tex] = mean resting pulse rate for men.

SO, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] = 72 beats/minute     {means that the mean resting pulse rate for men is 72 beats per minute}

Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] < 72 beats/minute      {means that the mean resting pulse rate for men is less than 72 beats per minute}

The test statistics that would be used here One-sample z-test statistics as we know about population standard deviation;

                            T.S. =  [tex]\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex]  ~ N(0,1)

where, [tex]\bar X[/tex] = sample mean mean resting pulse rate = [tex]\frac{\sum X}{n}[/tex]

                =  [tex]\frac{87+ 89+ 69 +63 +70 +65+ 88+ 84+ 58+ 53+ 66+ 70}{12}[/tex]  = 71.83 beats/minute

            [tex]\sigma[/tex] = population standard deviation = 2.6 beats per minute

            n = sample of men = 12

So, the test statistics  =  [tex]\frac{71.83 - 72}{\frac{2.6}{\sqrt{12} } }[/tex]    

                                     =  -0.23

The value of z test statistics is -0.23.

Also, P-value of the test statistics is given by;

            P(Z < -0.23) = 1 - P(Z [tex]\leq[/tex] 0.23)

                                 = 1 - 0.59095 = 0.40905

Now, at 0.05 significance level the z table gives critical value of -1.645 for left-tailed test.

Since our test statistic is more than the critical value of z as -0.23 > -1.645, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region due to which we fail to reject our null hypothesis.

Therefore, we conclude that the mean resting pulse rate for men is 72 beats per minute.

Answer:

The given equation is

[tex]y=4x+3[/tex]

To graph this equation, we need to create a table for all the coordinates pairs.

 X      Y

 0      3

-3/4    0

So, we have two points, (0,3) and (-3/4, 0). Now, we graph them to draw a straight line as the image attached shows.

To find the slope, we use those points.

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{0-3}{-\frac{3}{4} -0} =\frac{-3}{-\frac{3}{4} }\\ m=4[/tex]

So, the slope is 4.

The angle of inclination is found by the formula

[tex]tan \theta = m[/tex]

Where [tex]\theta[/tex] is the angle and [tex]m[/tex] is the slope.

[tex]\theta = tan^{-1}(4) \approx 76\°[/tex]

Therefore, the angle of inclination is 76°, approximately.

Unfortunately I can't read your answer options properly. The copied text is just too messed up. But hopefully the step-by-step calculation will help you.

Lemme know if it worked for you and if you have further questions.

Step-by-step explanation:

3x - 2y = -6

can be rewritten as

2y = 3x + 6

or simpler

y = 1.5x + 3

we know that it's parallel to this line, but we don't know how much lower or higher the new line will be, so let's set "+3" as an unknown variable.

y = 1.5x + b

(the letter b is now what we try to solve for)

now let's plug in the x-/y-Informations of the given point

2 = 1.5 * 4 + b

2 = 6 + b

-4 = b

so the new line is

y = 1.5x -4

(the given point lies on that line and it's parallel to the other line)

let's multiply everything by two to get closer to the original format

2y = 3x -8

it could also be expressed as

2y = -(-3x+8)

B. 31.4cm2
C. 565cm2
D. 15.7 cm2

Answers

Answer:

Option A. 283 cm²

Step-by-step explanation:

to find the area of the shaded sector, we use the formula:

 [tex]\frac{\text{angle given}}{360^\circ}\times \text{area of the circle}[/tex]

where area of the circle = πr²

∴ for the given circle,

[tex]\text{Area of the sector}=\frac{\text{given angle}}{360^\circ} \times \pi r^2[/tex]

                            =  [tex]\frac{100}{360}\times 3.14\times 18\times 18[/tex]

                            = [tex]\frac{100}{360}\times 1017.36[/tex]

                            = 282.6

                            ≈ 283 cm²

The approximate area of the shaded sector is 283 cm².

» Which expression is not equal to 30?

|(120 : 20) x (2+3)

(9 x 10) : (4 + 1) +12

(2 x 60 : 30) x (24 + 2)

2 + (30 - 8:4)

Answers

Answer:

Only expression that's not equal to 30 is option 3 which is; (2 x 60 : 30) x (24 + 2)

Step-by-step explanation:

We want to find which of the expression is not equal to 30.

1) (120 : 20) x (2+3)

Using BODMAS, we will solve the brackets first. So, we have;

(120/20) × 5

Note that a ratio implies division.

So, we have;

6 x 5 = 30

2) (9 x 10) : (4 + 1) + 12

Again, using BODMAS, solve the brackets first.

90 : 5 + 12

Ratio symbol is division and so it come before addition in BODMAS.

So, we have;

(90/5) + 12 = 18 + 12 = 30

3) (2 x 60 : 30) x (24 + 2)

Again, using BODMAS, solve the brackets first.

In the first bracket, we'll use division first before multiplication.

(2 x 60/30) x (26) =

2 x 2 x 26 = 104

4) 2 + (30 - 8:4)

Again, using BODMAS, solve the brackets first.

In the second bracket, division goes first. So,

2 + (30 - 8/4) = 2 + (30 - 2) = 2 + 28 = 30

So the only expression that's not equal to 30 is option 3 which is; (2 x 60 : 30) x (24 + 2)
