Sean got 4 over 5 pound of honey from a hive. He calculated the quotient of 4 over 5 ÷ 3 over 8 . Which statement shows the quotient and gives the most likely explanation of what Sean was trying to determine? (5 points)

He can make 2 2/15 bottles of honey with 3/8 pound of honey in each bottle.
He can make 12/40 of a bottle of honey with 3/8 pound of honey in each bottle.
He can get 2 2/15 pounds of honey if he divides the honey into 3/8 -pound portions.
He can get 12/40 pound of honey if he divides the honey into 3/8 -pound portions.

Answers

Answer:

The answer is A

Step-by-step explanation:

Writing the equation, it would look like (4/5) divided by (3/8) which gives you the answer 2 2/15 which is a mixed number btw. Only two of the answers uses this number, either A or C. C doesn't make any sense because the question already states that Sean has 4/5 pounds of honey. A makes sense because technically what you are doing is dividing the amount of honey Sean got into groups each holding 3/8 pounds.

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.

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.

Answer:

5x+15 = 45

5x =      30

30/5 = 6

x=6

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

-15 -15

——————

5x/5=30/5

x=6
