Answer:

d = 90

e = 39

f = 141

Step-by-step explanation:

<u>D</u>

d is 90 degrees because you see on the other side of d, there is the right angle symbol. This causes d to also equal 90.

<u>E</u>

e is 39 because of vertical angles theorem.

<u>F</u>

e + f = 180 because of supplementary angles theorem.

39 + f = 180

f = 180-39

f = 141

Hope this helped! If not, please let me know! <3

Natasha2012 [34]

Answer: 18 gallons.

Step-by-step explanation:

Let's call the total gallons that the container can hold <em>x.</em>

<em> </em>Then, based on the information given in the problem, you can write the following expression:

\frac{4}{9}x+4=\frac{2}{3}x

Now, you must solve for x, as you can see below. Therefore, you obtain the following result:

\frac{4}{9}x+4=\frac{2}{3}x\\\\4=\frac{2}{3}x-\frac{4}{9}x\\\\4=\frac{2}{9}x\\\\4*9=2x\\\\36=2x\\\\x=18\ gallons

Answer:

287.1 inches of the canvas.

Step-by-step explanation:

To solve this, we need to first figure out the total area of the canvas. To do that, multiply width by height.

29*33=957

Now set up your equation for solving for the area of the canvas that the rose covers.

x/957=30/100

We did it where: x is the area of the rose covers, 957 is the amount of inches that the canvas takes up, and the right side of the equation is the percent.

Now cross multiply.

100x=28,710

Now divide both sides by 100.

x=287.1

The red rose covers 287.1 inches of the canvas.
