timurjin [86]

Answer:

$g(t) = -16t^2+80t$ .

Step-by-step explanation:

We are given that $v=80$ and $h=0$ (because that's the ground), so substituting that into $g(t) = -16t^2+vt+h$ gives $g(t) = -16t^2+80t$ .

There are 7/8 kilograms of salt in the kitchen. Mrs. Jackson used 2/15 of salt when preparing dinner . How much salt did she use

neonofarm [45]

so since Mrs Jackson used 2/15 of 7/8, the amount she used is simply their product.

$\bf \stackrel{\textit{how much is }\frac{2}{15}\textit{ of }\frac{7}{8}?}{\cfrac{7}{8}\cdot \cfrac{2}{15}}\implies \cfrac{7}{15}\cdot \cfrac{2}{8}\implies \cfrac{7}{15}\cdot \cfrac{1}{4}\implies \cfrac{7}{60}$
