Chad has a bag with 2 mint sticks, 11 jelly treats, and 7 fruit tart chews. If he eats one piece every 4 minutes, what is the pr

scoray [572]

Answer:

first you add all the candies together to get 20 in the bag

2+11+7=20

jelly treat:

now we divide 11 by 20 to get a decimal

11/20= .55

multiply .55 by 100 to change it to a percentage

.55*100=55

first part of answer: He has a 55% chance of getting a jelly treat

mint stick:

divide 2 by 20 to get a decimal

2/20=.1

change .1 to a percent by multiplying by 100

.1*100=10

second part of answer: he has a 10% chance of getting a mint stick

astraxan [27]

Answer:

Approximately 87 minutes

Step-by-step explanation:

So first see how much of the reading 41 minutes is. It is 47%.

So now to find out how much 100% is, first find out how much 1% is.

Just divide by 47.

1% = $\frac{41}{47}$

And then multiply by 100 to get 100%

$\frac{4100}{47}$

That is 87.2340425532

Which is 87

Find an equation for the line that passes through the points (-1,2) and (5,5)

sesenic [268]

Answer:

-The equation for the problem:

$y = \frac{1}{2}x + \frac{5}{2}$

Step-by-step explanation:

-First, you need determine the slope of a line:

$m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ (where $(x_{1},y_{1})$ is the first coordinate and $(x_{2},y_{2})$ is the second coordinate).

-Use both points $(-1,2)$ and $(5,5)$ for the formula:

$m = \frac{5-2}{5+1}$

$m = \frac{3}{6}$

$m = \frac{1}{2}$

-After you have found the slope, use the point-slope formula and use the slope $\frac{1}{2}$ and the first coordinate, which is $(-1,2)$ , to solve the equation and put it in slope-intercept form:

$y-y_{1} = m (x-x_{1})$

$y-2 = \frac{1}{2} (x+1)$

-Solve:

$y-2 = \frac{1}{2} (x+1)$

$y-2 = \frac{1}{2}x + \frac{1}{2}$

$y = \frac{1}{2}x + \frac{5}{2}$

So, therefore the equation is $y = \frac{1}{2}x + \frac{5}{2}$ .
