Concept: Mathematical Analysis

(5 × 10^5) (13 × 10^6) (500000) * ( 13000000)Take 13 * 5 = 65 Hence 65000000000000Or 6.5 × 10^ 12x^m/x^n = x^(m-n)(8^-8)(8^3) alike bases so we just add the exponents Hence (8^-8+3)= (8^(-5))

There are 4 breakfast choices in a school cafeteria: Cereal, Granola Bar, Breakfast Sandwich, and Fruit. The percentage of students that chose cereal is 20%. If 60 students chose cereal, what is the total number of students that ate breakfast?GIVING BRAINLIEST
A.
120
B.
300
C.
320
D.
360

Answers

Answer:

B. 300

60 · 5 = 300

Answer:

300 students

Step-by-step explanation:

So just to summarize the question we know that 20% of students = 60 students. and we know that there are five 20 percents in 100% if that makes sense the example below explains it much clearer:

 1          2         3          4        5

20% + 20% + 20% + 20% + 20% = 100%

So to figure out how many students are in 100% we have to multiply it by 5 since there are 5 20 percents in 100%

So 60 students times 5 = 300

So, in conclusion, 300 students ate breakfast.

Answers

Answer:

C

Step-by-step explanation:

Let's see if this makes sense and applies to all of the pairs.

1. y will be 2

x will be 6

2=1/3(6)

1/3 times 6 is 2.

2. y will be 1

x will be 3

1=1/3(3)

1/3 times 3 is 1.

3. y will be 0

x will be 0

0=1/3(0)

1/3 times 0 is 0.

4. y will be -1

x will be -3

-1=1/3(-3)

1/3 times -3 is -1.

They all apply to C meaning that C is the right answer.

Answer:

1) A. y= 3x

2)B.

3) C

4) B. 38mm (This answer MAY be wrong, it may be right aswell though.)

they are complementary angles!

Answer:

These are complementary angles, meaning together they equal 90 degrees!

x=6

Step-by-step explanation:

Step 1: Find what 5x+15 should equal. Since together the angles equal 90, you must subtract 45 from 90.

90-45=45

Step 2: Set 5x+15 equal to 45

5x+15=45

Step 3: Solve

5x+15=45

The slope of the graph of the equation y= 2x-2 is 2. What is the y-Intercept?

Y-intercept:

Answers

Answer:

The y-intercept is 2

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

The way this graph is written in is called slope-intercept form.

It is written as y=ax+b, where

a=the slope

b=the y intercept

In this case b is -2, so that is the y intercept.

This makes sense because the slope is how much the line has incline and the y intercept is how high the line is.
