Answer:
i try my best to do that now just give me some time
Step-by-step explanation:
Nora's speed (5*8)m²/2h= 20 m²/h.
Zack's speed (4*9)m²/3h= 12 m²/h
Together for 1 h they paint (20+12) m²/h=32m²/h
Given area (10*12)m²=120 m²
120m² *1h/32m² = 3.75 h (3h 45 min) to paint 10m*12m together.
Answer:
Question 1: B = 0
Question 2: 23/2 or 11-1/2
Question 3: 663/6 or 110-3/6
Step-by-step explanation:
Question 1:
(-5²)+(9+4²)=5B
-25+9+16=5B
5B=-0
B=0/5=0
Question 2:
2-7/8×2-6/9×1-1/2
=23/8×24/9×3/2
=23/2
=11-1/2
Question3:
3-1/4×6-2/3×5-1/10
=13/4×20/3×51/10
=663/6
=110-3/6
Answer:
253.90

Answer: Choice D) Vertical Angles</h3>
Reason:
When two lines cross to form an X shape, the opposite pairs of angles are known as vertical angles. They are always congruent to one another.
They do not have to be vertically aligned (meaning the angles could be sitting side by side). Example: In problem 15, angle 1 and angle 3 are vertical angles that are congruent.
