Answer:

1.D , 2.G, 3. a. 4.f

Step-by-step explanation:

1. We have five x bars so we will represent that as

$5x$

We have 8 -1 boxes so that add up to be

$- 8$

On the right side we have 10 1 boxes so the right side value is 10.

Set up an equation.

$5x - 8 = 10$

Add 8 on both sides

$5x = 18$

Divide 5 by both sides

$x = 3.6$

2.Plug in 22 for g in all the answer choices to see if it correct or isolate g and see if it equal to 22.

G is the right answer , I'll do it both ways.

Plug in 22 for g

$2(22 - 6) = 32$

$2(16) = 32$

$32 = 32$

Isolate g

$2(g - 6) = 32$

$2g - 12 = 32$

$2g = 44$

$g = 22$

3.Llyod has 126 ounces of water. He spilled 36 ounces of water. We are trying to find the maximum number of cups he can fill after he spilled 36 ounces. This is represented by

$6c \leqslant126 - 36$

$6c \leqslant 90$

$c \leqslant 15$

so the answer is A

4.Plug in 18 and also any number greater than 18 and make sure the inequality true

F is true so F is the answer.

How do you figure out tax percentages?

Grace [21]

Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.
Make sure you put the sales tax into decimal form. You do this by taking the percentage and sliding the decimal point two places to the left:
7.5% sales tax becomes .075 in decimal form
3.4% sales tax becomes .034 in decimal form
5% sales tax becomes .05 in decimal form
Example: $60 (item cost) x .075 (sales tax) = $4.5 total sales tax

Question 1

777dan777 [17]

Answer:

There would be 94 tiles.

Step-by-step explanation:

The number of tiles is given by the following equation:

$n = 6 + 4p$

In which p is the current position.

How many tiles would there be in position 22?

This is n when $p = 22$ . So

$n = 6 + 4*22 = 6 + 88 = 94$

There would be 94 tiles.

Assume there are 365 days in a year.

Dahasolnce [82]

The chance of student 1's birthday being individual is 365/365 or 100%.
Then the chance of student 2's birthday being different is 364/365.
Then it's narrowed down to 363/365 for student 3 and so on until you get all 10 students.
If you multiply all these values together, the probability would come out at around 0.88305182223 or 0.88.

To get all the same birthday you'd have to the chance of one birthday, 1/365 and multiply this by itself 10 times. This will produce a very tiny number. In standard form this would be 2.3827x10'-26 or in normal terms: 0.23827109210000000000000000, so very small.

A softball fits snuggly inside a cubical box that is 4 inches on each side. What is the volume of the softball that fits snuggly

Natali5045456 [20]

Answer:

33.5 cubic inches.

Step-by-step explanation:

If the softball fits perfectly inside the cubical box, the softball is a sphere with diameter of 4 inches (radius os 2 inches).

The volume of a sphere is given by:

$V= \frac{4}{3}\pi r^3$

For r = 2 inches:

$V= \frac{4}{3}*3.14* 2^3\\V=33.5\ in^3$

The volume of the softball is 33.5 cubic inches.
