A baseball diamond is 90 feet square (NOT 90 square feet!). Coach Jack Handley runs from first base to second base at 25 feet pe

OverLord2011 [107]

Answer:

dx/dt = 5√5/2

Step-by-step explanation:

Given:

dx/dt = 25 feet per second

According to Pythagoras theorem:

x² + 90² = y²

We know that x = 30 ft

So,

x² + 90² = y²

30² + 90² = y²

y = 30√10

So,

x² + 90² = y²

By taking differentiate:

2x dx/dt = 2y dy/dt

[x/y][dx/dt] = dy/dt

dx/dt = 5√5/2

Chris made hamburgers for his family and they each had a diameter of 3 in. If he made 16 hamburgers.

Alenkasestr [34]

Answer:

The total area for all 16 hamburgers is 113.04 in².

Step-by-step explanation:

Given:

Chris made hamburgers for his family and they each had a diameter of 3 in.

If he made 16 hamburgers.

Now, to find the total area for all 16 hamburgers.

So, the diameter 3 in is given and we need first to find the radius:

$Radius\ (r)=\frac{Diameter}{2} =\frac{3}{2} =1.5\ in.$

Now, to get the area of a hamburger we put formula:

(Taking the value of π = 3.14.)

$Area=\pi r^2\\\\Area=3.14\times (1.5)^2\\\\Area=3.14\times 2.25\\\\Area=7.065\ in^2.$

Now. to get the total area of 16 hamburgers by multiplying 16 by the area of a hamburger:

$7.065\times 16\\\\=113.04\ in^2.$

Therefore, the total area for all 16 hamburgers is 113.04 in².

3. Jim invests $3500, compounded annually at 12% for 3 years. What is the total

irga5000 [103]

Answer:

None of the above, it should be $4760

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 12%/100 = 0.12 per year,

then, solving our equation

I = 3500 × 0.12 × 3 = 1260

I = $ 1,260.00

The simple interest accumulated

on a principal of $ 3,500.00

at a rate of 12% per year

for 3 years is $ 1,260.00
