Answer:

12.5%

Step-by-step explanation:

To change a fraction to o percentage , multiply by 100% , so

[tex]\frac{16}{128}[/tex] × 100%

= 0.125 × 100%

= 12.5%

Answer:

356.8 cm³

Step-by-step explanation:

Volume Sphere = [tex]\frac{4\pi r^3}{3}[/tex]

                          = [tex]\frac{4\pi *4.4^3}{3}[/tex]

                          = [tex]\frac{4\pi *85.184}{3}[/tex]

                          =  [tex]\frac{340.736\pi}{3}[/tex]

                          = 113.58π ≈ 356.8

Answer:

Is it perhaps one hundred and eighty (80)

Answer:

180

Step-by-step explanation:

180/2=90

90x2=180

180/4=45

180/5=36

180/6=30

180/9=20

the answer is 180 because it is less than 300, more than 150, and all of those numbers get whole numbers when they are divided. if you needed to know it is 2 sets of 90.

Variation can be direct, inverse or jointly

Jordan's first error is that he incorrectly calculated the value of proportionality constant

From the question, we understand that f varies directly as the square root of g.

This variation is represented as:

[tex]\mathbf{ f\ \alpha\ \frac{1}{\sqrt{g}}}[/tex]

Express as a equation

[tex]\mathbf{ f\ \ =\ k\frac{1}{\sqrt{g}}}[/tex]

When f = 4, k = 4.

So, we have:

[tex]\mathbf{ 4\ \ =\ k\frac{1}{\sqrt{4}}}[/tex]

[tex]\mathbf{ 4\ \ =\ \frac{k}{2}}[/tex]

Multiply both sides by 2

[tex]\mathbf{ k = 8}[/tex]

When g = 100, we have:

[tex]\mathbf{ f\ \ =\ k\frac{1}{\sqrt{g}}}[/tex]

[tex]\mathbf{ f\ \ =\ 8 \times \frac{1}{\sqrt{100}}}[/tex]

[tex]\mathbf{ f\ \ =\ 8 \times \frac{1}{10}}[/tex]

[tex]\mathbf{ f\ \ = 0.8}[/tex]

This means that, Jordan incorrectly calculated the value of proportionality constant

Answer:

the slope is undefined because it's a vertical line

Answer:

C

Step-by-step explanation:

To find the x- intercept let f(x) = 0 , then

3log(x - 5) + 2 = 0 ( subtract 2 from both sides )

3log(x - 5) = - 2 ( divide both sides by 3 )

log(x - 5) = - [tex]\frac{2}{3}[/tex] , then

x - 5 = [tex]10^{-\frac{2}{3} }[/tex] ( add 5 to both sides )

x = [tex]10^{-\frac{2}{3} }[/tex] + 5 → C

so this is what i think im not sure but ot will be seven dived by two . i hope this works

Answer:

n = {-1, 7}

Step-by-step explanation:

8n² - 56 = 48n

Subtract 48n from both sides

8n² - 48n - 56 = 0

Divide both sides by 8

n² - 6n - 7 = 0

Factor

alternately use the quadratic equation or complete the square

(n - 7)(n + 1) = 0

n = {-1, 7}

Answer:

The answer is A

Step-by-step explanation:

7^2=49 10^2=100

49+100 = 149

sqrt(149)

Answer:

A) [tex]\sqrt{149}[/tex]

Step-by-step explanation:

Pythagorean Theorem: [tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex]

c² = a² + b²

c² = 7² + 10²

c² = 49 + 100

c² = 149

c = [tex]\sqrt{149}[/tex]

Step-by-step explanation:

We know (Ohm second law) that [tex]R= \frac{k}{d^2}[/tex] where k inlcudes the rest of the parameters (material, lenght). In our situation we have k= [tex]0.4\cdot9 \Omega mm^2[/tex]. The moment the diameter becomes 8mm R becomes

[tex]R= {{0.4\cdot 9}\over{16}} \Omega = 0.225 \Omega[/tex]

Answer:y=10

Step-by-step explanation:u see the right side numbers increase by 7

Answer:

b) 2x=9=>x=9/2=4.5

c)x/5=7=>x=5×7=35

d)x/2=6.5=>x=6.5×2=13

Answer:

10

Step-by-step explanation:

A = 7, B = 2

7 = 2 * 3 + 1

7 mod 2 = 1

A = 8, B = 4

8 = 4 * 2 + 0

8 mod 4 = 0

A = 13, B = 5

13 = 5 * 2 + 3

13 mod 5 = 3

A = -16, B = 26

-16 = 26 * -1 + 10

-16 mod 26 = 10

Answer: x = 4,1

Step-by-step explanation:

Answer:

x = 4 or x = 1

Step-by-step explanation:

x² - 5x + 4 = 0

⇒ x² - 4x - x + 4 = 0

⇒ x (x - 4) - 1 (x - 4) = 0

⇒(x - 4)(x - 1) = 0

Therefore,

x - 4 = 0

⇒ x = 4

Again.

x - 1 = 0

⇒ x = 1

Hence, x = 4 or x = 1 :)
