Answer:
Correct option: second one -> Andy and Donald do not collide.
Step-by-step explanation:
To find if the boys collide, we need to find if there is a common value of t where the their x position are equal and their y position are equal. To do this, we make x(t) of Andy equal to x(t) of Donald, , then if there is a value for t, we do the same for y(t) and check if the values of t are equal:
24 + 23t = 12 + t
22t = -12
t = -0.5455 seconds
As the time is negative, it will not occur, so the boys will never collide.
Correct option: second one
You want to subtract 400,000 - 275,650.
400,000 - 275,650 = 124,350
124,350 more corn stalks were planted this year than last year.
Answer:
1.8 cm to the nearest tenth.
Step-by-step explanation:
The angle opposite side a = 180 - 105 - 15 = 60 degrees.
By the Sine Rule:
a / sin 60 = 2 / sin 105
a = 2 * sin60/ sin 105
= 1.79315
Answer:
Both are correct
Step-by-step explanation:
A store is having a 20% off sale. Micheal says that he can find the sale price of an item that has a regular price of "p" by evaluating the expression 0.8"p". Susan says that she can find the sale price for the same item by evaluating the expression "p"-0.2"p"
Store is having 20% off sale. Discount is 20%
LEt the regular price is 'p'
The discount price is 20% of p that is 0.2p
Sale price is original price - discount price
that is p - 0.2p . So Suna is correct
p - 0.2 p = 1p- 0.2p = 0.8p
So Michel is also correct
Hence, Both are correct
