The population of the US at the first census in 1790 was 3,929 people. By 2000 the population had increased to 284,000,000! What
OleMash [197]

Answer:

7,228,202%

Step-by-step explanation:

Population at first census in 1979 was 3929

If the Population had increased to 284,000,000 by 2000, the population increase will be;

284,000,000-3929

= 283,996,071

%increase in population = increment/initial population×100%

= 283,996,071/3929×100%

= 7,228,202%

This means that the population has increased by 7,228,202%

Solve -x/6 ≥ 3<br><br> A. x ≤ 18<br> B. x ≥ -18<br> C. x ≥ 18<br> D. x ≤ -18
Amiraneli [1.4K]

Answer:

D. x ≤ -18

Step-by-step explanation:

-x/6 ≥ 3

Multiply both sides by 6.

-x ≥ 3 × 6

-x ≥ 18

Multiply both sides by -1 and reverse the inequality.

x ≤ 18 × -1

x ≤ -18

5−4+7+1= 5 - 4 + 7 x + 1 = how is it no solution
laila [671]

Answer:

There is a solution. Here's how:

Step-by-step explanation:

So, you work out the problem, and you lay it out here:

5-4+7+1=5-4+7x+1.

First, you start by subtracting 5 from both sides, which cancels both of the 5s. Here's your equation now:

-4+7+1=-4+7x+1

Next, you add 4 to both sides, which makes you identify the identity.

Here's your equation now:

7+1=7x+1

Now, you subtract 1 from both sides.

Here's your equation now:

7=7x

Finally, divide both sides by 7, while identifying the identity.

x=1.

A cashier is unsure whether a group of customers ordered and ate a large or a medium pizza. Medium pizzas have a diameter of 12
Vinvika [58]
Answer: large pizza

Work:


1) You can determine the arc of a slice that is 1/12 of the whole pizza using the diameter.

2) First, calculate the total circumference of each pizza.

Formula for the circumference: 2π×radius

radius = diameter / 2

medium pizza: 2π (12 / 2) = 12π ≈ 37.70 in

large pizza: 2π (16/2) = 16π ≈ 50.27 in

3) arc of a 1/12 sector

arc of a 1/12 sector = circumferece × 1/12

medium pizza: 37.70 in / 12 = 3.14 in


large pizza: 50.27 in / 12 = 4.19 ↔ this is pretty close to 4.25


So, at the end we have found that the sector of 4.25 in left belongs to a large pizza.
