Answer:

b. 44/117

Step-by-step explanation:

Calculate tan(x) and tan(y) - can use calculator, or use Pythagoras' Theorem to calculate the length of the 3rd side of the right triangle (as you already have the side opposite to the angle and the hypontenuse, since sin(x) = O/A) and then determine tan(x) using tan(x) = O/A

Then use these values in the tan sum angle trig identity formula.

Eliseo pays $8.99 for a one-point canister of Georgia pecans. Write and solve a proportion to determine the cost of 4 ounces of
dlinn [17]

Answer:

The cost of 4 ounces of the pecans is <u>$2.24</u>.

Step-by-step explanation:

Given:

Eliseo pays $8.99 for a one-pound canister of Georgia pecans.

Now, to solve a proportion to determine the cost of 4 ounces of the pecans she needs for a particular recipe.

Let the cost of 4 ounces of the pecans be x.

1 pound = 16 ounces.

So, using unitary method we get cost of 1 ounces:

Cost of 16 ounces of the pecans = $8.99.

Cost of 1 ounces of the pecans = $8.99 ÷ 16 = $0.56.

According to question we set proportion:

4:x=1:0.56

So, to get by cross multiplication method:

\frac{4}{x} =\frac{1}{0.56}

<em>By cross multiplying we get:</em>

2.24=x

x=2.24

Thus, the cost of 4 ounces of the pecans is $2.24.

In the diagram, DEC is a
Leya [2.2K]

Step-by-step explanation:

This is a reflection. A reflection is a transformation involving two shapes looking the same by "bouncing it off a line without coming back.( meaning a reflection goes some where else not to it original poistion.)

Others reason why Why?

Line m is perpendicular to Line c.

B and E are equidistant from c that BC=CE.

Why the others are wrong.

While you could rotate this triangle 180 degrees, the transformation occurs about a line not a point. So using a rotation is wrong.

A translation doesnt occur about a line.

A guide reflection doesnt work since the transformations are already mapped correctly if you do the reflection. It doesnt need a translation.
