Answer:

no real solutions

see below

Step-by-step explanation:

It looks like a quadratic formula

t= -2.74 + sqrt(2.74^(2)-4*-4.9*(-10)) -: 2*-4.9

t = \frac{-2.74 +\sqrt{2.74^2 - 4*(-4.9)*(-10)} }{2*(-4.9)}

t = \frac{-2.74 + \sqrt{7.5076 -196} }{-9.8} = \frac{-2.74 + \sqrt{-188.4924} }{-9.8}

t = \frac{-2.74 + 13.73i}{-9.8 }

i = \sqrt{-1}

Answer:

Step-by-step explanation:

t=(-2.74 + sqrt(2.74^(2)-4*-4.9*(-10))) / -2*-4.9

t=(-2.74 + sqrt(7.5076-4*+49))/9.8

t=(-2.74 + sqrt(7.5076+45))/9.8

t=(-2.74 + sqrt(52.5076))/9.8

t=(-2.74/9.8)+(sqrt(52.5076))/9.8

this is simplest form, next will be rounded answers

t=0.45981763305

Solnce55 [7]

Answer:

3 chocolate bars, and 2 graham crackers

Someone forgot the marshmallows...... :P

Step-by-step explanation:

Chocolate bars = 8 pack

Graham Crackers = 12pack

To have no crackers or chocolate left over, we need to find LCM

Factors of 8:

8, 16, 24, 32, 40, 48, 56, 72....

Factors of 12:

12, 24, 36, 48, 60, 72

The smallest LCM is 24

Chocolate bars:

24/8 = 3

Graham Crackers:

24/12 = 2

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
