Answer:
100% means like everything, the total
Step-by-step explanation:
percent is like "out of a hundred"
so 100/100
is everything
The total
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
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.
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.
