The picture shows that a line crosses a pair of parallel lines ( or 2 lines are cut by a transversal ).
The angles with special names are:
- corresponding angles,
- interior angles,
- alternate exterior angles.
Corresponding angles are congruent ( here: ∠ 4 and ∠ 8 ).
Answer: ∠ 4 corresponds to ∠ 8.

Lin has picked 1 ½ cups of raspberries, which is enough for ¾ of a cake. How many cups does she need for the whole cake?

Llana [10]

Okay. So, based off of that, if you divide 1 1/2 (3/2) by 3/4, 3/2 * 4/3 is 12/6 or 2. 1/2 cups of raspberries is needed for each fourth of the cake. 1/2 * 4 = 2. Lin will need 2 cups of raspberries for the whole cake.

Jennifer has a taco stand.she found that her daily costs can be modeled by C(x)=x^2-40x+610. if she wants to keep her daily cost

Svetllana [295]

Plug in 300 for C(x), to get:
300= $x^{2} -40x=610$
Then subtract to get: 0= $0= x^{2} -40x+310$
Then use the quadratic formula and plug everything in. Use a calculator to simplify.

You'll get two answers: 29.486 and -0.513.
Since you can't sell "negative" tacos, use the positive solution
Around 29-30 tacos.

blsea [12.9K]

Answer:5r2+2

Step-by-step explanation:

Distribute the Negative Sign:

=4r2−3r+2+−1(−r2−3r)

=4r2+−3r+2+−1(−r2)+−1(−3r)

=4r2+−3r+2+r2+3r

Combine Like Terms:

=4r2+−3r+2+r2+3r

=(4r2+r2)+(−3r+3r)+(2)

=5r2+2
