The answer is 15

Step-by-step explanation:

She found that the area of the garden will be 127 and one-half square feet by using the equation Area = b h. If the height, h, of the parallelogram-shaped garden is 8 and one-half feet, what is the base, b, in feet? Hmm so it says that base times height equals 127 and one half square feet and the height is 8 and one half feet so you guessed it you have to divided 127 and one half square feet by 8 and one half feet which is 15.

The similarity ratio of  PQR to VXW is represented as 4 / 1

Similar triangles have the same shape but there sizes may vary. In similar triangles, corresponding sides are always in the same ratio.

The corresponding angles are congruent.

Therefore, the similarity ratio can be found as follows:

PQ / VX = PR / VW = QR / XW

Therefore,

8 / 2 = 4 / 1 = 8 / 2

4 / 1 = 4 / 1 = 4 / 1

Answer:

A. If Frank is on the toll road for 8.00 miles and then leaves the lane, how much will he have to pay total for the trip?

B. Each day, Susan has to pay a toll of $10.00 when she uses the toll lane to get to school. How many miles does Susan travel on the toll lane to get to school?

C. John started a carpool with his coworkers to save money. He and his three passengers split the cost of the toll. If each person pays about $2.31 (which includes their contribution to the toll lane entry fee), how many miles do they travel on the toll lane?

Step-by-step explanation:

the toll lane charges $0.25 fixed plus $0.75 per mile driven: fee = $0.25 + $0.75miles

a) Frank ⇒ $0.25 + (8 x $0.75) = $6.25

b) Susan ⇒ $10 - $0.25 = $9.75 / 0.75 = 13 miles

c) John ⇒ $2.31 x 3 = $6.93 - $0.25 = $6.68 / 0.75 = 8.91 ≈ 9 miles. Each passenger should pay $2.33 because the total toll lane fee is $7.

Answer:

360 pi in ^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the diameter is 12 so the radius is 1/2  the diameter

r = d/2 = 12/2 = 6

V = pi (6)^2 * 10

V = pi (36)*10

V = 360 pi in ^3

We can approximate pi by 3.14

V =1130.4 in ^3

Or we can approximate pi by using the pi button

V =1130.973355  in ^3

Answer:

Step-by-step explanation:

Considering the store in your neighborhood, price per pound of chicken is $2.89. The cost of 3 pounds is

3 × 2.89 = $8.67

Distance = 2.1 miles

The car averages about 22 miles per gallon in the city. It means that the number of gallons needed is

2.1/22 = 0.095 gallons

Cost of gas = $1.98/gallon

Cost of 0.095 gallons =

1.98 × 0.095 = $0.1881

Total cost = 8.67 + 0.1881 = $8.86

Considering the store across town, price per pound of chicken is $1.59. The cost of 3 pounds is

3 × 1.59 = $4.77

Distance = 8.6 miles

The car averages about 22 miles per gallon in the city. It means that the number of gallons needed is

8.6/22 = 0.39 gallons

Cost of gas = $1.98/gallon

Cost of 0.39 gallons =

1.98 × 0.39 = $0.77

Total cost = 4.77 + 0.77 = $5.54

Therefore, it is cheaper going to the further store. The amount that the cheaper option saves is

8.86 - 5.54 = $3.32

Let the height of cylinder be 'h'

[tex] = > Volume \: of \: cylinder = \pi {r}^{2} h \\ \\ = > 576 \cancel{\pi} = \cancel{ \pi}( {8}^{2} )h \\ \\ = > 576 = 64h \\ \\ = > 64h = 576 \\ \\ = > h = \frac{576}{64} \\ \\ = > h = 9 \: centimeters [/tex]

Height of cylinder = 9 centimeters

Answer:

The volume is 997.62 cubic units..

Step-by-step explanation:

We are given the following details:

The pyramid has a regular hexagonal base i.e. each side of hexagon is equal.

Side of hexagonal base, a = 8 units

Altitude of pyramid, h = 18 units

We have to find the volume of pyramid.

Formula:

[tex]V = \dfrac{1}{3} \times B \times h[/tex]

Where, B is the area of base of pyramid.

h is the height/altitude of pyramid

To calculate B:

Here, base is a hexagon with side 8 units.

[tex]\text{Area of hexagon, B }= 6 \times \dfrac{\sqrt{3}}{4}a^{2}[/tex]

Here, a = 8 units

[tex]\Rightarrow B = 6 \times \dfrac{\sqrt{3}}{4}\times 8^{2}\\\Rightarrow B = 166.27\text{ square units}[/tex]

Putting values of B and h in Formula of volume:

[tex]\Rightarrow V = \dfrac{1}{3} \times 166.27 \times 18\\\Rightarrow V = \dfrac{2992.89}{3} = 997.62\text{ cubic units}[/tex]

Hence, the volume is 997.62 cubic units.

Answer:

[tex]P(X<31)=P(\frac{X-\mu}{\sigma}<\frac{31-\mu}{\sigma})=P(Z<\frac{31-24.8}{6.2})=P(z<1)[/tex]

And we can find this probability using the normal standard distribution or excel and we got:

[tex]P(z<1)= 0.84[/tex]

And if we convert this into % we got 84% so then the best solution would be:

84%

Step-by-step explanation:

Let X the random variable that represent the size of gasoline tanks of a population, and for this case we know the distribution for X is given by:

[tex]X \sim N(24.8,6.2)[/tex]  

Where [tex]\mu=24.8[/tex] and [tex]\sigma=6.2[/tex]

We are interested on this probability

[tex]P(X<31)[/tex]

And we can use the z score formula given by:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

Using the last formula we got:

[tex]P(X<31)=P(\frac{X-\mu}{\sigma}<\frac{31-\mu}{\sigma})=P(Z<\frac{31-24.8}{6.2})=P(z<1)[/tex]

And we can find this probability using the normal standard distribution or excel and we got:

[tex]P(z<1)= 0.84[/tex]

And if we convert this into % we got 84% so then the best solution would be:

84%

Answer:

[tex]z=\frac{0.64 -0.5}{\sqrt{\frac{0.5(1-0.5)}{75}}}=2.43[/tex]  

Now we can calculate the p value with the following probability:

[tex]p_v =P(z>2.43)=0.0075 \approx 0.008[/tex]  

Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true proportion for this case is higher than 0.5

Step-by-step explanation:

Data given and notation

n=75 represent the random sample taken

[tex]\hat p=0.64[/tex] estimated proportion of interest

[tex]p_o=0.5[/tex] is the value that we want to test

[tex]\alpha=0.05[/tex] represent the significance level

Confidence=95% or 0.95

z would represent the statistic

[tex]p_v[/tex] represent the p value

System of hypothesis

We want to verify if the true proportion is higher than 0.5:  

Null hypothesis:[tex]p =0.5[/tex]  

Alternative hypothesis:[tex]p > 0.5[/tex]  

The statistic is given by:

[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)  

Replacing the info given we got:

[tex]z=\frac{0.64 -0.5}{\sqrt{\frac{0.5(1-0.5)}{75}}}=2.43[/tex]  

Now we can calculate the p value with the following probability:

[tex]p_v =P(z>2.43)=0.0075 \approx 0.008[/tex]  

Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true proportion for this case is higher than 0.5

Testing the hypothesis, it is found that:

The null hypothesis is:

[tex]H_0: p = 0.5[/tex]

The alternative hypothesis is:

[tex]H_0: p > 0.5[/tex].

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

For this problem, the parameters are: [tex]\overline{p} = 0.64, p = 0.5, n = 75[/tex].

The value of the test statistic is:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.64 - 0.5}{\sqrt{\frac{0.5(0.5)}{75}}}[/tex]

[tex]z = 2.42[/tex]

The p-value is the probability of finding a sample proportion above 0.64, which is 1 subtracted by the p-value of z = 2.42.

Looking at the z-table, z = 2.42 has a p-value of 0.992.

1 - 0.992 = 0.008, hence, the p-value is of 0.008.

Since the p-value of the test is 0.008 < 0.05, there is significant evidence to conclude that the proportion is greater than 0.5.

Answer:

Height = (x² + 10x + 25)

Step-by-step explanation:

We are given;

volume of cylinder; v = (x+5)•(x² + 10x + 25)π

Diameter = 2x + 10

So radius;r = diameter/2 = (2x + 10)/2 = x + 5

Now,formula for volume of cylinder is;

V = πr²h

Where r is radius and h is height

Plugging in the relevant values, we have;

(x+5)•(x² + 10x + 25)π = π(x + 5)*h

Dividing both sides by π(x + 5) gives us;

h = (x² + 10x + 25)

Answer:

The equation of the hyperbola is:

[tex]\frac{x^{2}}{76} - \frac{y^{2}}{12} = 1[/tex]

Step-by-step explanation:

The equation of a hyperbola centered in the origin in standard form is:

[tex]\frac{x^{2}}{a^{2}}-\frac{y^{2}}{b^{2}} = 1[/tex]

The distance between both vertexes is equal to:

[tex]2\cdot b = \sqrt{(0-0)^{2}+(\sqrt{12}+\sqrt{12})^{2}}[/tex]

[tex]2\cdot b = 2\cdot \sqrt{12}[/tex]

[tex]b = \sqrt{12}[/tex]

Now, the distance between any of the vertexes and origin is:

[tex]c = \sqrt{(0-0)^{2}+[(4-(-4)]^{2}}[/tex]

[tex]c = 8[/tex]

The remaining parameter of the hyperbola is determined by the following Pythagorean expression:

[tex]c^{2} = a^{2} - b^{2}[/tex]

[tex]a = \sqrt{c^{2}+b^{2}}[/tex]

[tex]a = \sqrt{64+12}[/tex]

[tex]a = \sqrt{76}[/tex]

The equation of the hyperbola is:

[tex]\frac{x^{2}}{76} - \frac{y^{2}}{12} = 1[/tex]

Answer:

The equation of the hyperbola is:

x²/76 - y²/12 = 1

Step-by-step explanation:

The standard for of an equation of a hyperbola centered in the origin is given as:

x²/a² - y²/b² = 1

The distance between both vertexes is:

2b, where b = √12

The distance between any of the vertexes and origin is:

c = 8

But a² = b² + c² (Pythagoras rule)

c² = a² - b²

8² = a² - 12

a² = 64 + 12 = 76

a = √76

Therefore, the equation of the hyperbola is:

x²/76 - y²/12 = 1
