2.5+105sin40 t -16 t^2 = 0
t = (-105sin(40) + sqrt(105^2sin^2(40)-4(-16)(2.5))) /2(2.5)
t = .235 seconds if i entered those right
Answer:
Sara's number is 28
Step-by-step explanation:
Let's assign Sara's number the variable x and solve this equation using the information provided.
"If you subtract 14 from my number"
x - 14
"and multiply the difference by - 3"
-3(x - 14)
"the result is – 42."
-3(x - 14) = -42
Now we can solve from here for x.
-3(x - 14) = -42
x - 14 = 14
x = 28
Answer:
Hence the each cheese piece weight equal to 0.3125 pounds
Step-by-step explanation:
Given;
5 pound of cheese block cut down into 16 pieces
To Find:
How much does each wedge of each cheese weigh
Solution:
Now each cheese weigh as follows:
<em>16 cheese pieces of ideal size are considered here so</em>
<em>16 piece equally contribute the the total weight of 5 pounds.</em>
So 5 pound in divided into 16 pieces
i.e 5/16=0.3125 pound per pieces
Hence the each cheese piece weight equal to 0.3125 pounds
i.e Each cheese piece is about 6.25 % of total weight i.e (6.25*16=100 %)
