Benjamin has enough icing to cover a 12-square-foot cake. He wants to use the icing to cover 2 equal-sized cakes. Which expressi
nirvana33 [79]

Answer:

       x^2=6ft^2\\\\x=\sqrt{6ft^2} \\\\x=\sqrt{6}ft

Explanation:

The area of each of the 2 equal-sized cakes shall be half of 12 ft²:

  • 12 ft² / 2 = 6 ft²

The area of a square shape is equal to the side length squared. Naming x the side length, you have the expression for the side length:

       area=x^2\\\\x^2=6ft^2\\\\x=\sqrt{6ft^2} \\\\x=\sqrt{6}ft

Factor the expression. x2 – 2x + 1 A. (x – 1)2 B. (x + 1)2 C. (x + 1)(x – 1)
Naddika [18.5K]

ANSWER

A.

{(x - 1)}^{2}

EXPLANATION

The given expression is

{x}^{2}  - 2x + 1

We split the middle term to obtain,

{x}^{2}  - x - x + 1

Factor to obtain

x(x - 1) - 1(x - 1)

Factor further to get,

(x - 1)(x - 1)

This is the same as;

{(x - 1)}^{2}

The correct choice is A

Answer:

Jack has to sell the old computers worth $8000

Step-by-step explanation:

Jack is paid for selling used computers = $15 per hour plus 5% commission

Let the revenue generated from selling the computers by him = $x

He will be paid for 40 hours = $(40×15) = $600

Commission earned by selling x computers = $0.05x

Total amount earned by him in 40 hours week = 600 + 0.05x

If this amount is $1000,

$1000 = $(600 + 0.05x)

0.05x = 1000 - 600

0.05x = 400

x = \frac{400}{0.05}

x = $8000

Therefore, Jack has to sell the old computers worth $8000.

Find the experimental probability that exactly 3 of 4
otez555 [7]

Answer:

4 / 20 (1 / 5)

20%

Step-by-step explanation:

The experimental probability is what actually happens in an experiment (as opposed to an authentic probability calculated from genetics).

In this experiment, there are 3 outcomes with :

3 tails and 1 head

(tails represent female, head represent male)

So, 4 / 20 of the time, this coin flip was what we call a "success" (meaning that it matches the guidelines that we want)

4 / 20 = 20% of the time

So, the probability of a group of 4 puppies being 3 females and 1 male is :

4 / 20 (1 / 5)

20%
