Ms. Hawkins wants to make awards for her students in the shape of pencils, using the design shown below. What is the area of the award to the nearest tenth of a square inch?

Answers

Answer 1

Answer:

74 in²

Step-by-step explanation:

Area of semicircle :

(πr²) ÷ 2

r = 3

(π * 9) / 2 = 14.137 in²

Area of triangle :

1/2 * base * height

Base = diameter = radius * 2 = 3 * 2 = 6

height = 4 inches

1/2 * 6 * 4 = 12in²

Area of rectangle :

Length * width

8in * 6 in

= 48 in²

Total area of pencil :

(14.137 + 12 + 48) in²

= 74.137 in²

The first platform of the Eiffel Tower is 2,280 inches above the ground. The second platform is 376 feet above the ground. How many yards separate the first platform from the second platform?​

Answers

Answer:

62.0496 yards separate the first platform from the second platform

Step-by-step explanation:

We have to make the conversion of both units to yards.

Each feet has 12 inches.

Each inch is 0.0278 yards.

The first platform of the Eiffel Tower is 2,280 inches above the ground.

So

2280*0.0278 = 63.384 yards above the ground.

The second platform is 376 feet above the ground.

So

376*12*0.0278 = 125.4336 yards above the ground

How many yards separate the first platform from the second platform?​

125.4336 - 63.384 = 62.0496

62.0496 yards separate the first platform from the second platform

The points (11, 13) and (7, 13) fall on a particular line. What is its equation in slope-intercept form?

Answers

Answer:

slope -intercept form y=mx+c

The equation of the straight line

                                 y = 0x +13

Step-by-step explanation:

Step(i):-

Given that the points

           (11 ,13) and (7,13)

The slope of the line

    [tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{13-13}{7-11} = \frac{0}{-4} =0[/tex]

Step(ii):-

Equation of the straight line passing through the point (11,13) and slope m=0

y - y₁ = m( x-x₁)

y - 13 =0(x-11)

y-13 =0

y =13

slope -intercept form y=mx+c

y = 0x +13

Which of the following is the equation of a line perpendicular to the line y =
-10x+1, passing through the point (5,7)?

Answers

Answer: The answer is C.

Step-by-step explanation: This is because when you solve you get y=1/10x+6.5 this graph runs through the point (5,7) and is perpendicular to y=-10x+1. In order for two equations to be perpendicular their slopes will be the opposite.

Step-by-step explanation:

(25m + 22) + (9m) = ?​

Answers

Answer:

Step-by-step explanation:

Simplifying

25m + 22 = 9m

Reorder the terms:

22 + 25m = 9m

Solving

22 + 25m = 9m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-9m' to each side of the equation.

22 + 25m + -9m = 9m + -9m

Combine like terms: 25m + -9m = 16m

22 + 16m = 9m + -9m

Combine like terms: 9m + -9m = 0

22 + 16m = 0

Add '-22' to each side of the equation.

22 + -22 + 16m = 0 + -22

Combine like terms: 22 + -22 = 0

0 + 16m = 0 + -22

16m = 0 + -22

Combine like terms: 0 + -22 = -22

16m = -22

Divide each side by '16'.

m = -1.375

Simplifying

m = -1.375

30 kilograms of beans costs $5. How many kilograms of beans can you buy for $20?

Answers

Answer:

120 kg

the kilograms of beans which can by for $20 are

30*(20/5) = 30.4 = 120 (kg)

Answer: 120 kilograms

Step-by-step explanation:

We can buy 30 kilograms of beans for $5 dollars. We need to find how many kilograms of beans we can buy for $20.

The first step is to divide 20 by 5. Then, using the quotient, we can multiply it by 30 to see how many kilograms of beans we can buy for $20.

20 ÷ 5 = 4.

4 x 30 = 120.

Therefore, we can buy 120 kilograms of beans for $20.

given a population mean of 27.1 with a standard deviation of 8.4 and a sample size of 10, answer these questions.
part A: what is the standard deviation of the sampling distribution of x hat? show your work.
PartB: what does the sample size need to be if you want the standard deviation of the sampling distribution of x hat to be 2.8? show your work.

Answers

Answer:

a) 2.66

b) 9

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

part A: what is the standard deviation of the sampling distribution of x hat? show your work.

We have that [tex]\sigma = 8.4, n = 10[/tex]. So

[tex]s = \frac{\sigma}{\sqrt{n}} = \frac{8.4}{\sqrt{10}} = 2.66[/tex]

PartB: what does the sample size need to be if you want the standard deviation of the sampling distribution of x hat to be 2.8?

This is n when [tex]s = 2.8[/tex]. So

[tex]s = \frac{\sigma}{\sqrt{n}}[/tex]

[tex]2.8 = \frac{8.4}{\sqrt{n}}[/tex]

[tex]2.8\sqrt{n} = 8.4[/tex]

[tex]\sqrt{n} = \frac{8.4}{2.8}[/tex]

[tex]\sqrt{n} = 3[/tex]

[tex](\sqrt{n})^2 = 3^2[/tex]

[tex]n = 9[/tex]

Given that L is a linear function, L (5) = 100 and L (9) = 150.
a. Determine the value of L (13)

Answers

Answer:

L(13) = 200

Step-by-step explanation:

Linear function:

A linear function has the following format:

[tex]y = mx + b[/tex]

In which m is the slope(how much y changes when x changes by 1) and b is the y-intercept(value of y when x = 0).

Finding the slope:

L (5) = 100 and L (9) = 150.

The slope is given by the change in the output(L, which is equals to y in the general formula) divided by the change in the input(x).

Change in the output: 150 - 100 = 50

Change in the input: 9 - 5 = 4

Slope: [tex]m = \frac{50}{4} = 12.5[/tex]

So

[tex]y = 12.5x + b[/tex]

L (5) = 100

So [tex]y(5) = 100[/tex], which means that when [tex]x = 5, y = 100[/tex], and we use this to find b.

[tex]y = 12.5x + b[/tex]

[tex]100 = 12.5*5 + b[/tex]

[tex]b = 100 - 12.5*5[/tex]

[tex]b = 37.5[/tex]

So

[tex]L(x) = 12.5x + 37.5[/tex]

a. Determine the value of L (13)

L when [tex]x = 13[/tex]. So

[tex]L(13) = 12.5*13 + 37.5 = 200[/tex]
