Answer:

21%, 0.21, 11/50, 2/9

Step-by-step explanation:

To arrange from least to greatest, we need to first express all as percemtage;

2/9 = 2/9 * 100 = 200/9 = 22.2%

21% = 0.21

0.21 = 0.21 * 100 = 21%

11/50 = 11/50 * 100 = 11*12 = 22%

Hence the values from least to greatest is 21%, 0.21, 11/50, 2/9

Scenario B: Analysts at an energy research institute compare the frequency of power outages caused by snowfall in different states over the past decade.

This is an example of observation.

Scenario C: To determine and compare the accuracies of pedometer X and pedometer Y, researchers randomly ask consumers to use one of the two pedometers and then analyze the results.

This is an example of experiment.

Scenario D: At a coffee shop, ten customers are randomly selected each day and asked how many times in a week they visit the shop.

This is an example of survey.

Step-by-step explanation:

Answer:

13

Step-by-step explanation:

To find the diameter, use the diameter formula.

d = 2r (r = radius)

In this case, we don't have a radius so to find the radius, use the radius formula.

r = [tex]\sqrt{A/\pi }[/tex] (A = area)

So, r = square root of 132.7/pi

r is approximately 6.5

Now we have the radius so we can find the diameter:

d = 2(6.5)

d = 13

Diameter is 13

The diameter of the circle is 13 cm.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The formula for the area of a circle is A = πr², where A is the area and r is the radius.

We are given the area of the circle, A = 132.7 cm²

Let's solve for the radius first:

A = πr²

132.7 = πr²

Divide both sides by π:

r² = 42.2

Take the square root of both sides:

r = 6.5

So the radius of the circle is approximately 6.5 cm.

Finally, the diameter is twice the radius:

d = 2r

= 13 cm.

Therefore, the diameter of the circle is approximately 13 cm.

Step-by-step explanation:

1. Formula for simple interest,

[tex]a = p(1 + rt)[/tex]

where

a = Final amount

p = Principal amount

r = annual interest rate

t = time in years

given p = 1250

r = 4.25/100 (r is a raw number, not percentage, so we need to divide 100 here to get the raw number)

t=4

Substitute values into formula to get a.

[tex]a = 1250(1 + (\frac{4.25}{100})(4)) \\ = 1250(1 + 0.17) \\ = 1250(1.17) \\ = 1462.50dollars[/tex]

Let's use the simple interest to calculate Henry's final amount first.

p = 5000

r = 4.2/100

t = 4

[tex]a = 5000(1 + ( \frac{4.2}{100} )(4)) \\ = 5000(1 + 0.168) \\ = 5000(1 .168) \\ = 5840 \: dollars[/tex]

To calculate the interest paid, just use the final amount minus the principal amount

[tex]a - p = 5840 - 5000 \\ = 840dollars[/tex]

Now we will do the exact same method for Ingrid.

p = 5,000

r = 3.9/100

t = 6

[tex]a = 5000(1 + ( \frac{3.9}{100} )(6)) \\ = 5000(1 + 0.234) \\ = 5000(1.234) \\ = 6170 \: dollars[/tex]

[tex]a - p = 6170 - 5000 \\ = 1170dollars[/tex]

Difference in interest between 2 of them =

Interest of Ingrid Loan - Interest of Henry Loan

= 1170 - 840

= $330

Given:

The function is

[tex]f(x+2)=2x+3[/tex]

To find:

The value f'(4).

Solution:

We have,

[tex]f(x+2)=2x+3[/tex]

Putting [tex]x+2=t[/tex] and [tex]x=t-2[/tex] we get

[tex]f(t)=2(t-2)+3[/tex]

[tex]f(t)=2t-4+3[/tex]

[tex]f(t)=2t-1[/tex]

Differentiate with respect to t.

[tex]f'(t)=2(1)-0[/tex]

[tex]f'(t)=2[/tex]

At [tex]t=4[/tex], we get

[tex]f'(4)=2[/tex]

Therefore, the value of f'(4) is 2.

Answer:

56 and 43

Step-by-step explanation:

(x+13)+x = 99

2x+13 = 99

2x = 99-13

2x = 86

x = 86/2

x = 43

Smaller number = 43

Larger number is 56

Check

56-43 = 13

56+43 = 99

Answer:

The two numbers are 43 and 56.

Step-by-step explanation:

Represent the numbers by x and y.

Then, according to the given information,

x + y = 99 and x - y = 13

Rewrite these two equations in a column:

x + y = 99

x -  y = 13

Solve this system of linear equations through elimination by addition/subtraction:

x + y = 99

x -  y = 13

---------------

2x = 112, so that x = 56

Next, find y by substituting 56 for x in either of the two equations:

56 - y = 13

This reduces to 43 - y = 0, or y = 43

The two numbers are 43 and 56.

Check:  Is the difference between 56 and 43 equal to 13?  YES

Is the sum of the numbers 56 and 43 equal to 99?  YES

Step-by-step explanation:

The slope of the line passing through two given points:  [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

(0, 5)   ⇒   x₁ = 0,  y₁ = 5

So, the slope:

                     [tex]m_1=\dfrac{2-5}{8-0}=\dfrac{-3}{8}=-\dfrac38[/tex]

(2, -1)   ⇒   x₁ = 2,  y₁ = -1

(6, 1)   ⇒     x₂ = 6,  y₂ = 1

The slope:

                     [tex]m_2=\dfrac{1-(-1)}{6-2}=\dfrac{2}{4}=\dfrac12[/tex]

(-3, -2)   ⇒   x₁ = -3,  y₁ = -2

(-1, -5)   ⇒     x₂ = -1,  y₂ = -5

The slope:

Answer and Step-by-step explanation:

The value of x is 75.

This is because we are given an Isosceles Triangle. Isosceles Triangles always have 2 legs/sides that are the same length, and because those two sides have the same length, it means their base angles have the same value as well.

So, Since the we have an Isosceles Triangle, the angle containing 75 is equal to the angle containing x.

Step-by-step explanation:

say S= shirt and P=pants

S+P=455

S= 95+P

95+P+P= 455

2P + 95 = 455

2P= 360

Answer:

1) m<RAS = 126

2) x = 144

Step-by-step explanation:

1)

10x + 36 + 6x = 180

16x + 36 = 180

16x = 144

x = 9

<RAS:

10x + 36

10(9) + 36 = 126

2)

54 + 90 + y = 180

y + 144 = 180

y = 36

x + y = 180

x + 36 = 180

x = 144
