Answer:
r=7
Step-by-step explanation:
6r-7+90+55=180
6r+138=180 ----- 6r=180-138
6r=42 ----- divide both sides by 6
r=7
(We get the 90 from the 90degrees in the middle of this supplementary angle and the total, 180, from the straight angle made from all three angles.)
hope this helps!
Answer:
Yes, women better at multitasking than men.
Step-by-step explanation:
Given
--- Men
--- Women
--- Women with greater average speed
Required
Does women better at multitasking?
When making comparison between two variables that are subjected to the same conditions;
If both variables have different mean values; the variable with the greater mean value performs better.
So, in this case:
means that women perform better than men, at multitasking.
Your answer to this would be:
A) ∠3, ∠6, ∠7
∠3 is congruent to ∠2 because of the vertical angles theorem. This theorem states vertical angles (angles opposite each other) are congruent.
∠6 is congruent to ∠2 because of the corresponding angles theorem. This theorem states corresponding angles (angles that are in the same position as their correspondent) are congruent.
∠7 is congruent to ∠2 because of the alternate exterior angles theorem. This theorem states that alternate exterior angles (angles on opposite sides of the transversal and outside the two parallel lines) are congruent.
Answer:
10
Step-by-step explanation:
(f + g)(x) = f (x) + g(x)
(f + g)(2) = f (2) + g(2)
= (-4) x 2 + (3 x 2 + 12)
= -8 + 18 = 10
3/8 + 1/12
LCD is 24
9/24 + 2/24
= 11/24 or 0.46
