vazorg [7]

Answer:

$\frac{1}{3} + \frac{1}{4}$

Step-by-step explanation:

We want to find an expression that has a value of

$\frac{7}{12}$

First option:

$\frac{7}{8} + 4 = \frac{7}{8} + \frac{32}{8} = \frac{39}{8} \ne \frac{7}{12}$

Second option:

$\frac{1}{3} + \frac{1}{4} = \frac{4}{12} + \frac{3}{12} = \frac{7}{12}$

Correct option

Third option

$\frac{6}{8} + \frac{1}{4} = \frac{3}{4} + \frac{1}{4} = 1$

Fourth option:

$2 \frac{1}{12} + 5 \frac{1}{12} = \frac{43}{6}$

A firecracker shoots up from a hill 160 feet high, with an initial speed of 90 feet per second. Using the formula H(t) = −16t2 +

Masja [62]

When the firecracker hits the ground, H(t) = 0.0 = -16t^2 + 90t + 160 Using the quadratic formula,t = (-90 +- sqrt(90^2 - 4(-16)(160))) / 2(-16)t = -1.42 ort = 7.04

The negative time is extraneous. Therefore,t = 7.04 s.
