Jillian sold 12% of the candy bars the class sold to raise money for a new water cooler in the school. If she sold 36 candy bars

Len [333]

Answer:

So we can write an equation to solve this:

12/100 = 36/x

And then we are going to solve for x

x(12/100) = 36

36 x (100/12) = 300

The total number of candy bars was 300

1. Use the expression 10 x ? where? represents a factor between 1 and 9. What is true about the digit in the ones place of each

marishachu [46]

We want to study a general product, and find information about the ones place.

We will see that the ones place is always zero.

We have the expression:

10×?

Where ? can be any number between 1 and 9 (only whole ones)

What is true about the digit of the ones place (the first digit at the left of the decimal point) in each product?

Let's give ? some different values and see what happens:

10×1 = 10

10×2 = 20

10×3 = 30

etc...

We can see that the ones place will always be equal to zero.

From base camp, a hiker walks 3.5 miles west and 1.5 miles north. Another hiker walks 2 miles east and 0.5 miles south. To the n

levacccp [35]

Answer:

The hikers are 5.9 miles apart.

Step-by-step explanation:

Let O represents the base camp,

Suppose after walking 3.5 miles west, first hiker's position is A, then after going 1.5 miles north from A his final position is B,

Similarly, after walking 2 miles east, second hiker's position is C then going towards 0.5 miles south his final position is D.

By making the diagram of this situation,

Let D' is the point in the line AB,

Such that, AD' = CD

In triangle BD'D,

BD' = AB + AD' = 1.5 + 0.5 = 2 miles,

DD' = AC = AO + OC = 3.5 + 2 = 5.5 miles,

By Pythagoras theorem,

$BD^2 = BD'^2 + DD'^2$

$BD = \sqrt{2^2 + 5.5^2}=\sqrt{4+30.25}=\sqrt{34.25}\approx 5.9$

Hence, the hikers are 5.9 miles apart.
