Kobe,A’mari and DJ are raising money for the football team to take a trip to San Diego.kobe collected $24.55 more than A‘Mari, A
Novay_Z [31]

Answer:

DJ= $39.58

Step-by-step explanation:

KOBE (K)

DJ (DJ)

A'MARI (A)

K= $24.55 + A

DJ= K –$15.60

Total Amount= $125.40

(24.55 + A) + (K – 15.60 + A) + A= 125.40

2A + K + 8.95 = $125.40

2A + K = $116.45

2A + (24.55 + A) = $116.45

3A = $91.90

A= 91.90 ÷ 3

A= $30.63

Therefore,

K= 24.55 + 30.63

K= $55.18

DJ= $55.18 – 15.60

DJ= $39.58

Joe makes belts. He has 9 buckles. He uses 12 rivets on each of 4 belts and 15 rivets on each of 2 belts. He has 22 rivets left
Lerok [7]

Answers:

1. There are rivets on the belts.

2. Extra information given in the problem:

a. He has 9 buckles.

b. He has 22 rivets left over.


Solution:

1. Total rivets on the belts=(12 rivets/belt)(4 belts)+(15 rivets/belt)(2 belts)

Total rivets on the belts=48 rivets+30 rivets

Total rivets on the belts=78 rivets


2. The extra information given in the problem is the information that we didn't use to solve it. In this case:

a. He has 9 buckles.

b. He has 22 rivets left over.

The height 'h' (in feet) of a ball in a baseball game can be modeled by h = -16t² + 28t + 8 , where 't' is the time (in seconds)
lidiya [134]

Answer:

  a)  No. t < 0 is not part of the useful domain of the function

  b) 2.0 seconds

Step-by-step explanation:

a) A graph of the function is shown below. It shows t-intercepts at t=-0.25 and t=2.0. We presume that t is measured forward from some event such as the ball being thrown or hit. The model's predicted ball location has no meaning prior to that event, when values of t are negative.

__

b) It is convenient to use a graphing calculator to find the t-intercepts. Or, the equation can be solved for h=0 any of several ways algebraically. One is by factoring.

  h = 0 = -16t² +28t +8 . . . . . . . . . . . . the ball hits the ground when h = 0

  0 = -4(4t² -7t -2) = -4(4t +1)(t -2)

This has t-intercepts where the factors are zero, at t=-1/4 and t=2.

The ball will hit the ground after 2 seconds.
