Number of students enrolled in Spanish = 42
Fraction of students enrolled in Spanish

Fraction of students enrolled in Spanish =
Answer:
t=0.64
Step-by-step explanation:
h = -16t^2 +4t +4
We want h =0 since it is hitting the ground
0 = -16t^2 +4t +4
Using the quadratic formula
a = -16 b = 4 c=4
-b ± sqrt( b^2 -4ac)
----------------------------
2a
-4 ± sqrt( 4^2 -4(-16)4)
----------------------------
2(-16)
-4 ± sqrt( 16+ 256)
----------------------------
-32
-4 ± sqrt( 272)
----------------------------
-32
-4 ± sqrt( 16*17)
----------------------------
-32
-4 ± sqrt( 16) sqrt(17)
----------------------------
-32
-4 ± 4 sqrt(17)
----------------------------
-32
Divide by -4
1 ± sqrt(17)
----------------------------

To the nearest hundredth
t=-0.39
t=0.64
Since time cannot be negative
t=0.64
Answer:
x=30
Step-by-step explanation:
Since the measure of an exterior angle is equal to the sum of any two angles in a triangle, the equation would be 4x-18=2x+6+36. Solve this, and we get x=30.
Hope this helped!
Number of plants = 5
Amount of soil present for 5 plants = 3/4 gallons
Now here we have to find how much soil will each plant get.
So we have to apply unitary method here to find how much would each plant get the share of soil.
Soil required by 5 plants = 3/4 gallons
Soil required by 1 plant = 3/4 divided by 5 = 3/20 gallons
Answer: Each plant will get 3/20 gallons of soil.
