The length of of each edge is 5 ft.

If the edge of the cube is marked as a, the the volume can be calculated as V = a³, so here given the $a= \sqrt[3]{V} = \sqrt[3]{125}=5$ volume V, we car write that:

Answer: 5 cm

Step-by-step explanation:

Given : The volume of a cube = 125 cubic inches.

The formula for the volume of a cube is :

$V=s^3$ , where s is the side-length .

Substitute V= 125 in the above formula ,

$125=s^3$

Taking cube root on both the sides , we get

$\sqrt[3]{125}=s\\\\\Rightarrow\ s= \sqrt[3]{5^3}=5$

Hence, the side length of cube= $5\ cm$

Factor by gcf 6x2+3x+21 The 2 is supposed to be small.

nlexa [21]

Given:

The expression is:

$6x^2+3x+21$

To find:

The factor of the given expression by GCF.

Solution:

We have,

$6x^2+3x+21$

Here, 3 is the greatest common factor (GCF) of $6x^2,3x,21$ .

Taking out GCF, we get

$6x^2+3x+21=3(2x^2+x+7)$

Therefore, the required factor form of the given expression is $3(2x^2+x+7)$ .

“Your salary is $25,000 and you will be receiving a 2.5% pay increase this year. What will your new salary be?”

Naddika [18.5K]

If your current salary is the 100%, and you get a 2.5% increase, that means the new salary would be 102.5% of 25,000. This percentage could also be written as 1.025, which you would multiply to 25,000 to get your new salary.

1.025 · 25,000 = 25,625

Therefore, your new salary would be $25,625

SSSSS [86.1K]

Given:

D be the event that a randomly chosen person has seen a dermatologist.

S be the event that a randomly chosen person has had surgery for skin cancer.

To find:

The correct notation for the probability that a randomly chosen person has had surgery for skin cancer, given that the person has seen a dermatologist.

Solution:

Conditional probability: Probability of A given B is:

$P(A|B)=\dfrac{P(A\cap B)}{P(B)}$

Let D be the event that a randomly chosen person has seen a dermatologist.

Let S be the event that a randomly chosen person has had surgery for skin cancer.

Using the conditional probability, the correct notation for the probability that a randomly chosen person has had surgery for skin cancer, given that the person has seen a dermatologist is P(S|D).

Therefore, the correct option is D.
