Answer:

3√512 = 8

Step-by-step explanation:

Step 1: Find the prime factors of 512

512 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2

Step 2: Pair the factors of 512 in a group of three, such that they form cubes.

512 = (2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2)

512 = 23 × 23 × 23

Using the law of exponent, we get;

512 = 29 [am.an = (a)m+n]

Or

512 = (23)3 [(am)n = amn]

512 = 83

Step 3: Now, we will apply cube root on both the sides to take out the factor (in cubes) as a single term.

3√512 = 3√(83)

So, here the cube root is eliminated by the cube of 8.

Hence, 3√512 = 8

are you sure those are all the options because it is -82

Answer:

D-$4,900

Step-by-step explanation:

Answer:

The answer is D. $4,900

Step-by-step explanation:

$196 in commissions  => a = 196

s = a / 0.04 = 196 / 0.04 = $4900 = Ann's sales

so the answer for Ann's sales is $4,900

Answer:

50+12x≥158

Step-by-step explanation:

starting with $50, adding $12 for every car washed (x), must be at least, but can be greater than, $158.

The required inequality for Silvio to earn more than $158 in one day is, $50 + 12x ≥ 158.

Given that,
Silvio works at a car wash. He earns $50 per day and $12 per car washed. Silvio wants to earn at least $158 in 1 day.
To determine the inequality represents the number of cars (C) Silvio must wash to reach his goal.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
Let the number of cars washed by Silvio be x,
According to the question,
Silvio works at a car wash. He earns $50 per day and $12 per car washed.
Total earning of the day = $50 + 12x
Silvio wants to earn at least $158 in 1 day. So, his total earnings of the day must be greater equal to $158.
$50 + 12x ≥ 158.

Thus, the required inequality for Silvio to earn more than $158 in one day is, $50 + 12x ≥ 158.

Answer:

Step-by-step explanation: 30%

Answer:

280

Step-by-step explanation:

160 divided by 4 is 40 then times that by 7 and u get 280

Answer:

280 miles

Step-by-step explanation:

First you have to find how many miles a car travels in 1 hour. (160 ÷ 4 = 40).

Then, once you find that, you multiply 40 by 7. (280)

Answer:

Part A: S^2= 3V/H

Part B: S =[tex]\sqrt{3\frac{v}{h} }[/tex]

Part C: s=√3* 2,433,400 /138=230 metres

Part D: This website says that the length of Khufu's Pyramid is about 230 meters. My calculation was correct.  

Part E: S = √3*2,115,072/ 136 =216 metres

Part F: The length of Khafre's pyramid is about 215.5  My calculation was a little off, but not by much.

Part G: 14 meters longer

Step-by-step explanation:

Part A:

I am going to solve:

So,

V=1/3 [tex]HS^{2}[/tex]

Then, multiply both sides by 3:

V x 3= 1/3 [tex]HS^{2}[/tex] x 3

So,

3V=[tex]HS^{2}[/tex]

Then, we divide by H:

[tex]\frac{3V}{H}[/tex]=[tex]\frac{HSs^{2} }{H}[/tex]

So,

[tex]\frac{3V}{H}[/tex]= [tex]s^{2}[/tex]

Then switch sides:

[tex]s^{2}[/tex]= [tex]\frac{3V}{H}[/tex]

Answer:

x has the values -4 and -3

Step-by-step explanation:

x² + 7x + 12 = 0

x² + 3x + 4x + 12 = 0

x(x + 3) + 4(x + 3) = 0

(x + 4)(x + 3) = 0

Answer:

2676 students

Step-by-step explanation:

Total number of students =. 40,140

During study:

Sample size = 210

Number of samples who speak 3 or more languages = 14

Proportion who speak 3 or more languages :

14 / 210 = 0.0666666

Applying the proportion to the total. Population :

0.0666666 * total number of students

0.0666666 * 40140

= 2675.997324

= approximately 2676 students

Complete Question:

The amount of money, y, pizzeria W makes by selling x pizzas can be modeled by the equation y = 15x. The relationship of the amount of money pizzeria L makes is shown in the following graph.

Which pizzeria makes more money per pizza?

A. Pizzeria L makes more money per pizza.

B. Pizzeria W makes more money per pizza.

C. They make the same amount per pizza.

Answer:

B. Pizzeria W makes more money per pizza.

Step-by-step explanation:

The proportional relationship showing how amount of money made(y) is related to the amount of pizzas sold (x) for pizzeria W is given by the equation y = 15x.

the constant of proportionality/unit rate, k = 15.

This represents the amount in dollars, made per pizza.

So, Pizzeria W makes $15 per pizza.

For Pizzeria L, using any point on the line, say, (2, 24),

k = y/x = 24/2 = 12.

This represents the unit rate, which is the amount Pizzeria L makes per pizza.

Thus, Pizzeria L makes $12 per pizza.

We can conclude that, Pizzeria W makes more money per pizza.
