laila [671]

Answer:

Rate of change  =  4,06 f/min

Step-by-step explanation:

The ascendent length  28 9/10   =  289/ 10

The time for that ascendent maneuver is total time 17 1/8 minutes  - spended time in the elevation 10 minutes, then

17 1/8  =  137/8

137/8  - 10   =  ( 137 - 80 ) /8   =  57/8 minutes

The rate of change in the diver´s elevation is

289 / 10 / 57/8

Rate of change  =  289*8/ 57*10

Rate of change  =  2312 / 570 ft/min

Rate of change  =  4,06 f/min

padilas [110]

Answer:

The perimeter of the basketball court is <u>276 feet²</u>.

Step-by-step explanation:

Given:

The basketball court at Johnson Elementary School is the shape of a rectangle.

It is 92 feet long and 46 feet wide.

Now, to find the perimeter of the basketball court.

Length = 92 feet.

Width = 46 feet.

So, to get the perimeter we put formula:

Perimeter=2(length+width)

Perimeter=2(92+46)

Perimeter=2\times 138

Perimeter=276\ feet^2.

Therefore, the perimeter of the basketball court is 276 feet².

Provide answers for part a,b, and c. Show work for part c.
schepotkina [342]

Answer:

Step-by-step explanation:

PART A

The Pythagoras theorem is expressed as

Hypotenuse^2 = opposite side^2 + adjacent side^2

PART 2

The hypotenuse is the longest side of the triangle. Looking at the given triangle, the longest side is the side with the length of 7. Therefore, hypotenuse = 7

PART C

To determine x, we will apply the Pythagoras theorem as stated above.

Opposite side = √14

Adjacent side = x

Therefore

7^2 = x^2 + (√14)^2

49 = x^2 + 14

x^2 = 49-14 = 35

Taking square root of both sides of the equation, it becomes

x = √35

x = 5.92
