So you want to plug in the height for h and solve for t
36 = -16t^2+14t+36
So you get 14/16 which simplifies to
7/8 seconds
Hope this helped!
Answer:
137 m²
Formula's:
- area of rectangle: length + width
- area of triangle: 1/2 * base * height
Explanation:
⇒ area of rec + area of rec + area of rec + area of triangle
⇒ 2 * 4 + 7 * 6 + 8 * 9 + 1/2 * 6 * 5
⇒ 8 + 42 + 72 + 15
⇒ 137 m²
Answer: B: 3/8 x 1/5
Step-by-step explanation:
It is B because when you are dividing fractions you do keep, change, flip.
1. 3/8 divided by 5
2. 3/8 divided by 5/1
3. Do KCF, 3/8 (keep) x (change) 1/5 (flip)
4. Equals 3/8 x 1/5
Answer:
3 over 12
Step-by-step explanation:
3 over 12
Factorise to (5z-1)(z-4) = 0
then put 5z-1 = 0 so 5z = 1 z = 1/5
z-4=0 z = 4
z = 1/5 and 4
