Answer:
n=14/9
Step-by-step explanation:
3/4n+2/3=11/6
3/4n=11/6-2/3
3/4n=11/6-4/6
3/4n=7/6
n=(7/6)/(3/4)
n=(7/6)(4/3)
n=28/18
simplify
n=14/9
Answer:
The answer is B.
Step-by-step explanation:
Given that each box has 9 pineapples. So if there are 6 boxes, there will be 54 pineapples :
6 × 9 = 54 pineapples
Y = -2x - 3
When I put this into y2-y1/x2-x1 (equation to find slope) I did the coordinate pairs (3,-9) and (4,-11). When you plug it in it’s -11+9/4-3. This gets you -2/1, which is -2. That’s your slope. Then, in order to get the y-intercept, you can use any of those pairs. I did -9 = 3(-2) + b. -9=-6 + b and in the end this gets you -3 = b. So the full equation is y = -2x - 3.
Answer:
At time t = 2.03 s height of ball = 93 feet
Step-by-step explanation:
We have h(t) = − 16 t² + v₀ t + h₀
A baseball is thrown vertically upward at a rate of 65 feet per second from an initial height of 4 feet.
Initial speed, v₀ = 65 ft/s
Initial height, h₀ = 4 ft
Substituting
h(t) = − 16 t² + 65 t + 4
Now we need to find time when h(t) = 93 ft
93 = − 16 t² + 65 t + 4
16 t² - 65 t + 89 = 0
t = 2.03 s or t = 2.03 s
At time t = 2.03 s height of ball = 93 feet
