PLEASE HELP! THANKS!

If you add everything up then
14x-2=180
14x=182
x= 13

So the angles would equal
2(13)+1= 27
3(13)-3= 36
9(13)= 117
The angles are 27 36 and 117
Which makes the smallest angle 27 which is B.

Andrew fish tank holds 144 gallons of water. To clean the tank, he drains the water at a rate the water at a rate of 6 gallons p

Kobotan [32]

Answer:

8 minutes

Step-by-step explanation:

Since the level of the tank needs to be at two-thirds its original level, then this means that Andrew needs to drain only one-third of the fish tank. Therefore the amount of time it would take can easily be solved with this 2-step equation...

6t = 144 * $\frac{1}{3}$ .... first multiply the right side of the equation

6t = 48 ... next divide both sides by 6

t = 8

Finally, we can see that it will take Andrew 8 minutes to drain the tank to two-thirds of its original level.

A monk crossbred plants which can have purple or white flowers and obtained 511 plants with white flowers and 337 plants with pu

Zepler [3.9K]

Answer:

For purple;

P(p) = 337/848 = 0.40

For white;

P(w) = 511/848 = 0.60

Step-by-step explanation:

Given;

Number of plants with purple flowers P = 337

Number of plants with white flowers W = 511

Total T = 337 + 511 = 848

For purple;

the empirical Probability that a plant had purple flowers P(p) is

P(p) = Number of plants with purple flowers/total number of plants

P(p) = P/T

Substituting the values, we have;

P(p) = 337/848 = 0.40

For white;

the empirical Probability that a plant had white flowers P(w) is

P(w) = Number of plants with white flowers/total number of plants

P(w) = W/T

Substituting the values, we have;

P(w) = 511/848 = 0.60

HELP PLEASE Write the inequality that models the number granola bars (12) you need to buy.

Goshia [24]

The correct question in the attached figure

Let
x-------------> the number of granola bars
y-------------> the pounds of fruit

we know that

if 12 bars------------> cost $12
1 bars--------------> X
X=12/12---> x=$1
1 bar---------> cost $1

if 9 pounds of fruit----------> cost $36
1 pound-------------------> X
X=36/9--------> x=$4
1 pound -------> cost $4

expression for the total cost=(1)*x+(4)*y----------> x+4y
x=12
y=9
then
the total cost=12+4*9----- $48

an inequality that compares
the total cost with the amount you have to spend is
x+4y<=48

using a graph tool see the attached figure

the inequality that models the number of granola bars you need to buy is

x<=12 the solution for the number of granola bars is the interval [0,12]
