Answer:

The area is between 0 square units and 1 square unit.

Step-by-step explanation:

For example if you multiply 0.85 x 0.85 you would get 0.7225.

0.7225 is between 0 and 1.

Answer:

the solution set is (-infinity, -8) ∪ (-8, 1/5)

Step-by-step explanation:

x + 8 changes sign at x = -8.  

I'll assume you meant 5x - 1 (as 5x+- is meaningless).  5x - 1 changes sign at x = 1/5.

Subdivide the x-axis using the two x-values found above:

(negative infinity, -8), (-8, 1/5), (1/5, infinity.

Choose a representative value from each interval.  I'm choosing x = -10, x = 0 and x = 1.

Now test the given inequality at each of these x-values.  Is the result true or false?

 x + 8

---------- > 0

5x - 1

For x = -10:

-10 + 8

--------------- > 0 => -2/(-51) => 2/51     This is TRUE

5(-10) - 1

For x = 1:

 1 + 8

---------- > 0  =>  9/4     This is TRUE

  5 - 1

For x = 0:

     8

---------- > 0    This is FALSE

    - 1

Therefore the solution set is (-infinity, -8) ∪ (-8, 1/5)

Answer:

1.84

Step-by-step explanation:

I think you gave the wrong information because if you divided 81 by 44 you will get 1.84...

Answer:

no then can not be both

Step-by-step explanation:

vertical angles require the intersection of 2 straight lines and then they are the opposite of where they intersect

adjacent are next to each other

Answer:

no, vertical angles can never be adjacent. adjacent angles are the ones next to each other while vertical angles are opposite from each other

Answer:

We have 15 Nickels and 10 Dimes.

Step-by-step explanation:

This is a system of equations! [Literally in a class reviewing that rn}

Lets make a chart:

    Number of Coins  x  Value of Coin = Total Value

Dimes  |   d               |   10                          | 10d

Nickels |   n               |  5                           | 5n

So, When you have a System of Equations with Money, One equations is about the value of the money, and the other about the number of coins.

The First Equation [Number of Coins]:

D + N = 25

the Second Equation [Value of Money]:

10D + 5N = 175

I will use Elimination to solve this, however, graphing and substitution works too.

ELIMINATION:

Multiply First equation by -5

-5[D + N = 25] = -5D - 5N = -125

Add the Two Equations vertically.

-5D - 5N = -125

10D + 5n = 175

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

5D = 50

Divide both sides by 5.

5D/5 = 50/5

D = 10

Substitute D= 10 In any equation and solve for the other variable.

10 + N = 25

Subtract 10 from both sides.

10 - 10 + N = 25 - 10

N = 15

So, we have 15 Nickels and 10 Dimes.

Answer:

$22,200 over all

Step-by-step explanation:

The compound interest after 20 years is $22700.

Compound interest is the interest you earn on interest. Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

For the given situation,

The principle, p = $10,000

Rate of interest, r = 6.1% = 0.061

Compounded continuously, n = 1

Number of years, T = 20

The amount formula of compound interest is

[tex]A=p(1+\frac{r}{n} )^{T}[/tex]

On substituting the above values,

⇒ [tex]A=10000(1+\frac{0.061}{1} )^{20}[/tex]

⇒ [tex]A=10000(1.061)^{20}[/tex]

⇒ [tex]A=32681.9[/tex] ≈ [tex]32682[/tex]

The compound interest can be calculated as

[tex]CI=A-P[/tex]

⇒ [tex]CI=32682-10000[/tex]

⇒ [tex]CI=22682[/tex] ≈ [tex]22700[/tex]

Hence we can conclude that the compound interest after 20 years is $22700.

Answer:

Median: 25

Upper quartile: 30

Lower quartile: 20

IQR: 10

Step-by-step explanation:

The nice thing here is they already put them in order :)

16, 18, 20, 22, 24,    26, 28, 30, 32, 34

For the median, it's the middle number of the ordered data set. Unfortunately here, there is an even number of entries. In that case, we average the middle two numbers, 24 and 26. 24 + 26 = 50/2 = 25

For lower quartile/Q1, you take the middle number of the bottom half of the data set. Bottom half: 16, 18, 20, 22, 24...so the middle is 20

For the upper quartile/Q3, you take the middle number of the top half of the data set. Upper half: 26, 28, 30, 32, 34...so the middle is 30

For interquartile range/IQR, you calculate the range from third to first quartile: 30-20 = 10

Answer:

about 48%

Step-by-step explanation:

I just took the quiz

The percentage of the Cherry Hill residents polled supported Zhang is 51.61%.

A percentage is a number or ratio that can be expressed as a fraction of 100. Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

For the given situation,

The relative frequency table shows a survey of two communities asked residents which candidate they supported for a local election.

Candidates supported Zhang in Cherry hill = 0.32

Total candidates in Cherry hill = 0.62

Percentage of the Cherry Hill residents polled supported Zhang is

⇒ [tex]\frac{0.32}{0.62}(100)[/tex]

⇒ [tex]0.5161(100)[/tex]

⇒ [tex]51.61\%[/tex]

Hence we can conclude that the percentage of the Cherry Hill residents polled supported Zhang is 51.61%.

Answer:

pi 50 x^4

Step-by-step explanation:

The volume of a cylinder is

V = pi r^2 h

Answer:

D. 132,651 cubes

Step-by-step explanation:

You're looking for how many cubes fit in the box. Remember cubic means 3 dimensions and squared means 2 dimensions.

Use length x width x height and converting the 4.25 feet to inches...

4.25×12=51

51×51×51=132,651

Meaning 132,651 one inch cubes would fit.

Answer:

132,651 cubes

Step-by-step explanation:

4.25 ft = 51 inches

51 x 51 x51 = 132,651 inches

1 x 1 x 1 = 1 inch cubes

so

132,651 divided by 1 = 132,651.

Answer:

[tex]26.68\ \text{feet}[/tex]

Step-by-step explanation:

a = 100 feet

[tex]\angle B=20^{\circ}[/tex]

[tex]\angle C=45^{\circ}[/tex]

[tex]\angle A=180-(20+45)=115^{\circ}[/tex]

From sine rule we have

[tex]\dfrac{\sin B}{b}=\dfrac{\sin A}{a}\\\Rightarrow b=\dfrac{\sin B}{\sin A}a\\\Rightarrow b=\dfrac{\sin 20^{\circ}}{\sin 115^{\circ}}\times 100\\\Rightarrow b=37.73\ \text{feet}[/tex]

[tex]\sin C=\dfrac{h}{b}\\\Rightarrow h=b\sin C\\\Rightarrow h=37.73\times \sin 45^{\circ}\\\Rightarrow h=26.68\ \text{feet}[/tex]

Answer:

[tex]t_{7}[/tex] = 22   is the answer to the first question

d = 4 is the answer to the second question

Step-by-step explanation:

use the formula [tex]a_{n} = a + (n - 1)d[/tex]

6 - 2 = 4 = d  a = -2  n = 7

[tex]t_{7}[/tex] = -2 + (7 - 1)4

   = -2 + 6(4)

   = -2 + 24

   = 22

use the formula [tex]a_{n} = a + (n - 1)d[/tex]

a = 7

n = 4    

[tex]a_{4} = 28[/tex]

28 = 7 + (7 - 1)d

     = 4 + 6d

24 = 6d

d = 4

Answer:

b

Step-by-step explanation:

A  pyramid is a three-dimensional object. The base of a pyramid is a polygon. the top and the base of a polygon forms a triangle

The volume of a pyramid = 1/3 × (area of base x height)

volume = 36.67 m3

area = 10.0 m2,

height = ?

36.67 = 1/3 x (10 x h)

multiply both sides of the equation by 3

110.01 = 10h

divide both sides by 10

h = 11.0001 m

what they are saying is n is 3 so 3+11=14
