Question:

Simplify the following expression:

[tex]4^{-\frac{11}{3}[/tex]÷[tex]4^{-\frac{2}{3} }[/tex]

A.1/12

B. 1/64

C.12

D.64

Answer:

B. 1/64

Answer:

[tex]increase = 9149840 - 8863052 \\ = 286788 \\ \% \: increase = \frac{286788}{8863052} \times 100\% \\ = 3.24\%[/tex]

Answer:

=3.23577% increase

Step-by-step explanation:

1) subtract final value minus starting value

2) divide that amount by the absolute value of the starting value

3) multiply by 100 to get the percent increase

4) if the percentage bis negative, it means there was a decrease and not an increase

Answer:

0.9

Step-by-step explanation:

His sample had a mean thickness of 148 microns and a standard deviation of 3.3 microns with a 95% confidence interval for the mean thickness.

Solution:

The z score shows by how many standard deviations the raw score is above or below the mean.

Given that:

The mean (μ) = 148 microns, standard deviation (σ) = 3.3 microns, sample size (n) = 50 and confidence interval (C) = 95%

α = 1 - C = 1 - 0.95 = 0.05

α/2 = 0.05/2 = 0.025

The z score of α/2 is the same as the z score of 0.475 (1 - 0.025) which is equal to 1.96

The margin of error (E) is given by:

[tex]E=z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } \\\\E=1.96*\frac{3.3}{\sqrt{50} } \\\\E=0.9\ microns[/tex]

Answer:

75cents for the fudge while the bubble gum are .50 cents

Step-by-step explanation:

because we got that 75 cents is for the fudge so they we multiple 75cents w 2 and when you sum it up if it makes the amount they spent then its right

Answer:

The horizontal shift depends on the value of h . When h>0 , the horizontal shift is described as: g(x)=f(x+h) g ( x ) = f ( x + h ) - The graph is shifted to the left h units. g(x)=f(x−h) g ( x ) = f ( x - h ) - The graph is shifted to the right h units.

Answer:

25.000

Step-by-step explanation:

75.000(2/3) = 50.000

75.000-50.000= 25.000

Answer:

I don't get it what is the question ❓

Answer:

Square root of 77.44 = height and length of gray squares = 8.8 cm

Since there are 3 squares that make up the height of that object 8.8 cm * 3 =

26.4 cm (the height of  3 gray squares

Square root of 4.84 = 2.2 cm

So the total height = 26.4 + 2.2 = 28.6 cm

Answer:

A. 7/2      B.y - 0 = 7/2(x + 2)

Step-by-step explanation:

y2 - y1 / x2 - x1

7 - 0 / 0 - (-2)

7 / 2

= 7/2

y - 0 = 7/2(x + 2)

Answer:

1. 3, 9, 19, 33

Step-by-step explanation:

2(4)²+1 = 2(16)+1 = 32+1 = 33

Answer:

D.

Step-by-step explanation:

In order to eliminate, the numbers must eliminate. If the second equation is multiplied by 3, then the 3 and the -3 can be eliminated. Since it is multiple choice, we can plug in x = 12 and y = 10 to see if they are correct. 12 + 30 = 42 and 24 - 10 = 14, so D is correct.

The value of x is 88° enjoy

Answer:

r = √3V/√πh

Step-by-step explanation:

V = 1/3πr²h

where,

V = volume of the cone

r = radius of the cone and

h = height of the cone.

Rewrite the formula to solve for the positive value of r in terms of h and V.

V = 1/3πr²h

V = 1/3 * π * r² * h

r² = V ÷ 1/3 * π * h

r² = V ÷ πh/3

r² = V × 3/πh

r² = 3V / πh

find the square root of both sides

√r² = √3V / πh

r = √3V/πh

Also written as

r = √3V/√πh

Answer:

-2

Step-by-step explanation:

(fxg)(0)

= f(0) x g(0)

so (fxg)(0) = -2

Answer:

B:34

Step-by-step explanation:

16² + 30² = c²

256 + 900= 1156

square root of 1156 is 34

Answer:

x = 13 , y = 7

Step-by-step explanation:

x + 2y = 27 => x = 27 - 2y ---------( 1 )

2x - y = 19 ------------ ( 2 )

Substitute ( 1 ) in ( 2 ) :

                         2x - y = 19

                         2(27 - 2y) - y = 19

                         54 - 4y - y = 19

                             -5y = 19 - 54

                             -5y = -35

                                y = 7

Substitute y = 7 in ( 1 ) :

                            x = 27 - 2y

                            x = 27 - 2( 7 )

                           x = 27 - 14

                          x = 13

Answer:

x = 20

Step-by-step explanation:

The triangles are similar

3          (3+5)

----- = ----------

12        (12+x)

Using cross products

3(12+x) = 12*(3+5)

3(12+x) = 12*8

3(12+x) = 96

Divide by 3

3(12+x)/3 = 96/3

12+x = 32

Subtract 12

12+x-12 =32-12

x = 32-12

x =20

Answer:

see explanation

Step-by-step explanation:

A linear pair of angles sum to 180° , then

3x + 10 + 4x - 5 = 180

7x + 5 = 180 ( subtract 5 from both sides )

7x = 175 ( divide both sides by 7 )

x = 25

Then

3x + 10 = 3(25) + 10 = 75 + 10 = 85°

4x - 5 = 4(25) - 5 = 100 - 5 = 95°

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

3x - 3 + 5x + 7 = 180

8x + 4 = 180 ( subtract 4 from both sides )

8x = 176 ( divide both sides by 8 )

x = 22

Then

3x - 3 = 3(22) - 3 = 66 - 3 = 63°

5x + 7 = 5(22) + 7 = 110 + 7 = 117°

Answer:

see explanation

Step-by-step explanation:

A linear pair of angles sum to 180° , then

3x + 10 + 4x - 5 = 180

7x + 5 = 180 ( subtract 5 from both sides )

7x = 175 ( divide both sides by 7 )

x = 25

Then

3x + 10 = 3(25) + 10 = 75 + 10 = 85°

4x - 5 = 4(25) - 5 = 100 - 5 = 95°

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

3x - 3 + 5x + 7 = 180

8x + 4 = 180 ( subtract 4 from both sides )

8x = 176 ( divide both sides by 8 )

x = 22

Then

3x - 3 = 3(22) - 3 = 66 - 3 = 63°

5x + 7 = 5(22) + 7 = 110 + 7 = 117°
