Note:

You missed adding the answer options.

But, I am solving the given expression to determine its equivalent so that you could get an idea and could easily determine all the options which would be equivalent to the result we would get.

Answer:

[tex]5^{\frac{1}{3}}\:\times 25^{\frac{1}{3}}=5[/tex]

Step-by-step explanation:

Given the expression

[tex]5^{\frac{1}{3}}\times \:25^{\frac{1}{3}}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^mb^m=\left(ab\right)^m[/tex]

[tex]5^{\frac{1}{3}}\times \:25^{\frac{1}{3}}=\left(5\times \:25\right)^{\frac{1}{3}}[/tex]

               [tex]=125^{\frac{1}{3}}[/tex]

[tex]\mathrm{Factor\:the\:number:\:}\:125=5^3[/tex]

               [tex]=\left(5^3\right)^{\frac{1}{3}}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc}[/tex]

               [tex]=\left(5^3\right)^{\frac{1}{3}}=5^{3\times \frac{1}{3}}=5[/tex]

Thus,

[tex]5^{\frac{1}{3}}\:\times 25^{\frac{1}{3}}=5[/tex]

What is the surface area and volume of an rectangular prism with sides 6

Answers

The surface area and volume of the rectangular prism are equal to 216 square units and 216 cubic units, respectively.

What are the surface area and the volume of a rectangular prism?

Despite the brevity of the statement, we can find the answer by considering the rectangular prism as a cube, that is, every side has a measure of 6 units. The volume is equal to the product of the base area and the height of the prism and the surface area is equal to the sum of the areas of the six faces:

V = 6³

V = 216

A = 6 · 6²

A = 6³

A = 216

The surface area and volume of the rectangular prism are equal to 216 square units and 216 cubic units, respectively.

Happy holiday seasons!

Answer:

the water level decreases by 5 feet per hour

Step-by-step explanation:

firstly the bar is going downwards, hence ,making a loss, decrease etc

so 1st and 3rd are out

initially we had 30ft of water

after

1 hr = 25 ft

2hrs = 20 ft

- 5 ft decreased again from the previous time checked

3hrs = 15 ft

- 5 ft decreased 1 hr ago

hence the water level decreases by 5 feet per hour

Mia lives on a farm and has 21 bulls and 21 cows. What percentage of the bovine population is bulls? Please explain how to get your answer as simple as possible! Thank you :)

Answers

Answer:

50%

Step-by-step explanation:

To find the percentage of something, you need to put the thing over the total as a fraction, then multiply that fraction by 100%.

Percentage of the bulls = [tex]\frac{21}{21+21}[/tex] × 100%

                                       = [tex]\frac{21}{42}[/tex] × 100%

                                       = 50%

manuel has $15 to spend.on apps and music. Apps cost $2 each and songs cost $1 each. If x represents the number of apps purchased and y represents the number of songs purchased, write a linear equation that represents the combination of apps and songs manuel can purchase.

Answers

Answer:

2x + y = 15

Step-by-step explanation:

Total amount with Manuel = $15

Cost of apps = $2

Cost of song = $1

x = number of apps purchased

y = number of songs purchased

Cost of apps × number of apps purchased + Cost of song × number of songs purchased = Total amount with Manuel

2*x + 1*y = 15

2x + y = 15

The linear equation that represents the combination of apps and songs manuel can purchase is 2x + y = 15

i require help (why this stuff so hard)

Answers

Answer:

x should be -3

Step-by-step explanation:

f(x) = 5/3x + 10

f(-3) = (5*-3)/3 + 10

f(-3) = -15/3 + 10

f(-3) = -5 + 10

f(-3) = 5

g(x) = -2x - 1

g(-3) = -2(-3) - 1

Negatives cancel out

g(-3) = 2(3) - 1

g(-3) = 6 - 1

g(-3) = 5

5 is equal to 5, so x should be -3 in this case.
