Answer:
No
Step-by-step explanation:
negative numbers work the opposite of how positive numbers work. Think about it like this. -12 is 12 units less than 0 and -12.5 is 12.5 units less than 0 which means that -12.5 is less than -12
145 = -16 t² + 80 t +s
s = ?
v = v0 - at
0 = 80 - at
80 = at
s = 80 t - at²/2
s = 80 t - 80t/2
s = 40 t
Finally: 145 = -16 t² + 80 t + 40 t
16 t² - 120 t + 145 = 0
We will solve this quadratic equation:
t = [120 +√ ( (-120)²- 4 · 16 · 145 )] / 32
t = [120 + √ (14400 - 9280) ] / 32
t = (120 + 71.55) / 32 = 5.98 ≈ 6 s
Answer:D) 6 seconds
It takes 250 g of pasta and 240 ml of sauce to make one batch of spaghetti and it takes 600g of pasta and 700ml of sauce to make one batch of lasagna.
Case 1: Pasta
The chef wants to make spaghetti and lasagna using more than 4000 g of pasta.
S denote the number of batches of spaghetti he makes and L the number of batches of lasagna he makes.
So the equation becomes :

Case 2: Sauce
chef wants to make spaghetti and lasagna using more than 5000 ml of sauce.
S denote the number of batches of spaghetti he makes and L the number of batches of lasagna he makes.
So the equation becomes:
Answer :
The two equations are :
For pasta: 
For sauce:
Answer:

Step-by-step explanation:
The volume of a cube is 200 cm².
We need to find the edge length of the cube.
The formula for the volume of a cube is given by :

a is the side of the cube
![a=\sqrt[3]{200} \\\\=(200)^{\dfrac{1}{3}}\\\\=(25\times 8)^{\dfrac{1}{3}}\\\\=(25)^{\dfrac{1}{3}}\times (8)^{\dfrac{1}{3}}\\\\=2(25)^{\dfrac{1}{3}}](https://tex.z-dn.net/?f=a%3D%5Csqrt%5B3%5D%7B200%7D%20%5C%5C%5C%5C%3D%28200%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C%3D%2825%5Ctimes%208%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C%3D%2825%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5Ctimes%20%288%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C%3D2%2825%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D)
So, the edge length of the cube is
