I’m sorry I’m on a time crunch I wish I could help you with all of them! But I check the first 3 ones and they are correct amazing job have a wonderful day ☺️❤️
It’s A, Because if you do KCF (Keep Change Flip) It would be 1/6 X 7/5.
First, subtract to get the difference.
2.85 – 2.78 = 0.07
Next, divide 2.78 by 100
2.78 ÷ 100 = 0.0278
So, 0.0278 is 1%. Divide 0.07 by 0.0278 to get the answer.
0.07 ÷ 0.0278 ≈ 2.518
2.518 ≈2.5
Therefore, the percentage increase is approximately 2.5% (that's the answer).
Hope this helps!
Answer:
72,220 inches per minute
Step-by-step explanation:
A car's wheels spins at 1000 revolutions per minute. The diameter of the wheels is 23 inches.
1 revolution = 
radians
Speed 
r is the radius , theta is the angle and t is the time
We know diameter = 23 , then radius = 23/2
Speed 
Value of pi = 3.14
speed = 23000* 3.14= 72220 inches/ minute
Answer:
10x² + 6x + 3xy + 3y - y²
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, as shown
(2x + y)(5x - y + 3)
= 2x(5x - y + 3) + y(5x - y + 3) ← distributing
= 10x² - 2xy + 6x + 5xy - y² + 3y ( collect like terms )
= 10x² + 6x + 3xy + 3y - y²
