Answer:

AC = 4.5 units

Step-by-step explanation:

Given question is incomplete without the figure; find the figure attached.

By applying angle bisector theorem in the given triangle ABC,

(Since, AD is the angle bisector of ∠BAC)

\frac{AC}{CD}=\frac{AB}{BD}

\frac{AC}{2.5}= \frac{6.8}{3.8}

AC = \frac{6.8\times 2.5}{3.8}

AC = 4.47

AC ≈ 4.5 units

Length of side AC in the given triangle = 4.5 units.

In one baseball season, Peter hit twice the difference of the number of home runs Alice hit and 6. Altogether, they hit 18 home
saw5 [17]
Below is the solution:

There are two equations to be solved here.  The first one we assign variables to the home runs Peter hits, P, and Alice hits, A. P=2*(A-6) The second equation is the sum of both players home runs.P + A = 18Solving for P yieldsP=18-A We substitute the solution for P into the first equation and solve for A.(18-A) = 2*(A-6)18 - A = 2A - 123A = 30A = 10 Now that A is known, we can plug it into either equations for P to find how many home runs Peter hitsP=18 - (10) = 8orP=2((10)-4) = 8

Pls help, I don’t understand how to do this
MAVERICK [17]

Answer:

5 parts are shaded and 4 parts are white so:

There are 9 parts all together.

We can then form ratio's of the white areas and the shaded areas:

White Area Ratio =

\frac{4}{9}

Shaded Area Ratio =

\frac{5}{9}

Let the area of sqaure be equated to x, which means let the entire area of the square equal to x:

x = Area of whole square

Now we can form an equation :

\frac{5}{9} x = 165

So now we just need to solve for x:

x = \frac{165}{ \frac{5}{9} }

x = 297

The area of the square is:

297 {cm}^{2}

andrew-mc [135]

Answer: 1404 cubic feet.

Step-by-step explanation:

Formula :

Volume of a rectangular prism is given by :

Volume= Area of the base x Height.

Given : Talishas bedroom is a rectangular prism.

The area of the floor = 156 square feet

The height of the floor = 9 feet

Then , the volume of Talishas bedroom =  Area of floor x Height

= 156 × 9=1404 cubic feet.

Hence, the volume of Talishas bedroom= 1404 cubic feet.
