Jeremy bakes two pans of brownies that are the same size. One pan has nuts in it and the other pan does not. He cuts the pan with nuts into 8 equal pieces. He cuts the pan without nuts into 16 equal pieces. His friends eat 2 brownies with nuts and 3 brownies without nuts. Did they eat more of the brownies with nuts or without nuts?

5. A team of mountain climbers makes camp 1.48 kilometers above sea level. They climb another 2.91
kilometers to the mountain's peak. How tall is the mountain?

Answers

Answer:

4.3068

Step-by-step explanation:

so what you do is 1.48 x 2.91

Answer:

= 4.39km

Step-by-step explanation:

Camp distance = 1.48Km

Distance travelled afterwards = 2.91km

Mountain Height = total distance travelled

So total distance = 1.48 + 2.91  

                         = 4.39km -----------> final answer

A rock is thrown from the top of a ladder. The function
h(t) = –16t2 + 120t + 10 gives the height of the rock t seconds after it is
thrown a certain number of feet.
What is the height of the rock at 5 seconds?

Answers

Answer:

h'(t)=88

Step-by-step explanation:

h'(t)=d/dt (-16t x 2 + 120t + 10

h'(t)=d/dt (-32t + 120t + 10)

h'(t)=d/dt (88t + 10)

h'(t)=d/dt (88t) + d/dt (10)

h'(t)=88 + 0
