Step-by-step explanation:
Given that Elijah threw a ball from a height of 4 feet. The ball reached maximum height of 16 feet after 2seconds
Let vertical component of his speed be v
When it reaches maximum height its velocity becomes 0
Hence
height reached by the ball =
When h=12(16-4) we get g=gravity =32
Hence 12 =2v-16(4)
v=38
Hence 
where h is calculated from the height of hand i.e. 4 feet
When it touches the ground h =-4
When it starts falling then distance travelled = 16 feet
Initial velocity =0 Accn due to gracity =32 feet
Using these we can write
So after 3 minutes from start the ball would reach the ground
Answer:
12
Step-by-step explanation:
We know that 1/3 of a pizza is cheese meaning that 6 pizzas are made of cheese and there are only two leaving the rest pepperoni and 12 are left if we subtract the cheese pizzas minus the 18 pizzas we have 12 which are pepperoni.
Answer:
shortest side = 15
Step-by-step explanation:
The question is a bit ambiguous. Do you mean (3/4) x or do you mean 3/(4x)?
I'll take it to be the first one.
(x + 3) + 4(x - 13) + (3/4)x = 3x + 6 Remove the brackets on the left
x + 3 + 4x - 52 + 0.75 x = 3x + 6 Combine
5.75x - 49 = 3x + 6 Subtract 3x from both sides.
2.75x - 49 = 6 Add 49 to both sides
2.75x = 55 Divide by 2.75
x = 55/ 2.75
x = 20
Now for the shortest side
x + 3 = 23
4(x - 13) = 4(20 - 13) = 4*7 = 28
(3/4)*20 = 15
The shortest side = 15
substitute x for y-1
2(y-1)-y=6 distribute
2y-2-y=6 subtract y in 2y
y-2=6 add 2 to get y by itself
y=8
Put y back into equation x=y-1
x=8-1
X=7
