Answer:

6. 19 candles

7. 6 pills

Step-by-step explanation:

6.  If a particular candle burns for 2 3/4 hours (=2.75) and you want to use similar candles to burn one at a time over 10 days for 5 hours each day, find the total number of hours:  10 x 5 = 50 hours.  Then, divide by the amount of time it takes for one candle to burn: 10÷2.75 = 18.18.  Since the answer is a decimal, you will need to round to the next whole number = 19 candles.

7.  Given the rules that no more than three pills may be taken in a four-hour period and each pill must be taken 1 1/2 hours (=1.5) apart, you can take the total number of hours (10) and divide by the time between each pill (1.5):

10 ÷ 1.5 = 6.7

Since you won't take part of a pill, the most you can take is 6 and because the intervals are 1.5 hours, 1.5 + 1.5 + 1.5 = 4.5, you will not have taken more than 3 in any four hour period.

A, first find the slope of the line shown, which is 2x+1
slope is rise/over run, with the y-intercept being on 1

When looking at rate of change, it's really just telling you to look at the slope and how steep it is. The more steeper it is, the higher the rate of change. (as close as it is to being a vertical line). Since the slope here is 2. Look for one that has a slope greater than 2, which is 3. Therefore the answer

A. 3x-1

Hope this helps!

Jocelyn is 1.75 meters tall. At 1 p.m., she measures the length of a tree's shadow to be
bija089 [108]

The height of the tree = 15.34m

What is height?

Height is a way to measure someone or something from base to top or head to toe. In other words, height tells how tall someone or something is.

Given,

the height of Jocelyn = 1.75m

At 1 pm = 43.85

She is sway from tree = 38.6

therefore, 43.85 - 38.6 = 5.25

Therefore, height

1.75/5.25 = h/43.35

5.25h = 76.73

therefore, height = 15.34

What is the resulting equation when the expression for y in the second equation is substituted into the first equation? 3x y = 1
Natali5045456 [20]

After putting the value of y from the second equation to the first equation, the resultant equation is x=5.

GIven:

The equations are:

3x + y = 1\\&#10;y = 6 - 4x

It is required to put the value of y from second equation to the first equation.

<h3>How to solve equations?</h3>

The value of y from the second equation is,

&#10;y = 6 - 4x

Now, put this value of y in the first equation as,

3x + y = 1\\&#10;3x+(6 - 4x)=1\\&#10;3x+6-4x=1\\&#10;-x=-5\\&#10;x=5

Therefore, after putting the value of y from the second equation to the first equation, the resultant equation is x=5.
