1. Dennis made a 500 km trip in five hours. For the first two hours, Dennis had an average speed of 150 km/h. For the last two hours, Dennis had an average speed of 100 km/h. Which of the following is true about Dennis' trip? (25 Points) Dennis must have maintained a constant velocity throughout his trip. Dennis must have maintained a constant speed throughout his trip. O Dennis must have stopped for an hour in the middle of this trip Wich statemeent correctly discribes the locaton and Dennis must have driven without stopping during his trip
Answer:
The correct option is;
Dennis must have stopped for an hour in the middle of this trip
Step-by-step explanation:
The given parameters are;
The distance Dennis covered in 5 hours = 500 km
Dennis's average speed in the first two hours = 150 km/h
Dennis's average speed in the last two hours = 100 km/h
Therefore;
Dennis traveled 150 km/h × 2 h = 300 km in the first two hours
Dennis traveled 100 km/h × 2 h = 200 km in the last two hours
Which gives, Dennis traveled 300 km + 200 km in 2h + 2h = 4h
Therefore, Dennis traveled 500 km in 4 hours and Dennis must have stopped for an hour in the middle of this trip.

Sharon drives 1/3 of the total distance to big bend on the first day. On the second day, she travels 1/3 of the total distance in the morning and 1/6 of the total distance in the afternoon. How much of the total distance has sharon driven by the end of the day?
Answer:
5/6
Step-by-step explanation:
Given that :
Fraction of total distance driven on first day = 1/3
Second day :
Fraction driven in the morning = 1/3
Fraction driven in the afternoon = 1/6
Total distance driven by the end of the day :
1/3 + 1/3 + 1/6
Take the L. C. M
(2 + 2 + 1) / 6
= 5 /6
5/6 of the total distance

How many times will you roll a number less than 4 on a number cube if you rolled it 250 times ?
A) 100
B) 90
C) 125
D) 85
Answer:
C. 125
Step-by-step explanation:
The ratio for one time is 3:6. It is 3:6 because there are 3 numbers less than 4 on a number cube. You can now compare the two ratios.
3:6 = x/250.
This is a ratio, so both numbers would have to be multiplied by the same number. 6 * 41 = 250.
3 * 41 = 123.
(41 was rounded from 41.6666667. This is why it comes out to 123.)

A company paid $391 for 15 bushes and 8 bonsai trees. They had to purchase 9 more bushes and 5 more bonsai trees for $241. What is the cost of each bush and bonsai tree? Enter your answers in the
boxes below.
Bushes:
Bonsai Tree:
Answer:
The cost of each bushes is $9.00
The cost of each bonsai trees is $32.00
Step-by-step explanation:
The given parameters are
The amount the company paid for 15 bushes and 8 bonsai trees = $391
The amount for which the company purchased 9 more bushes and 5 more bonsai trees = $241
Let x represent the cost of each bushes and let y represent the cost of each Bonsai Trees, we have;
15 × x + 8 × y = 391...(1)
9 × x + 5 × y = 241...(2)
We make y the subject of both equations to get;
For equation (1), we have;
15·x + 8·y = 391
15·x + 8·y = 391
8·y = 391 - 15·x
y = 391/8 - 15/8·x
For equation (2), we have;
9 × x + 5 × y = 241
5·y = 241 - 9·x
y = 241/5 - 9/5·x
Equating both equations, gives;
391/8 - 15/8·x = 241/5 - 9/5·x
391/8 - 241/5 = 15/8·x - 9/5·x = 0.075·x
0.675 = 0.075·x
x = 0.675/0.075 = 9
x = 9
Therefore, the cost of each bushes = x = $9.00
From, y = 241/5 - 9/5·x, we have;
y = 241/5 - 9/5×9 = 32
y = 32
Therefore, the cost of each bonsai trees = y = $32.00
Kiley is measuring the change in length of a blade of grass each day. Which are the best units for Kiley to report her findings?
THE BEST UNITS FOR KILEY TO REPORT HER FINDINGS IS CENTIMETRE
Unit conversion is a way of converting some common units into another without changing their real value. The best unit for Kiley to report her findings is cms per day.
What is Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
Given that Kiley is measuring the change in length of a blade of grass each day. Now, since the length of the blade of grass is too minute, therefore, it can be measured in either cm, mm, or inches.
But, mm is too small for this measurement, while inches are too big to measure the significant change in the length.
Hence, the best unit for Kiley to report her findings is cms per day.

Greg is making accessories for the soccer team. He uses 813.44 inches of fabric on headbands for 37 players and 4 coaches. He also uses 358.16 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Total number of people including players and coach is, T = 37 + 4 = 41.
Total fabric used for making headbands is, h = 813.44 inches.
So, amount of fabric used for each person is :
[tex]F_h = \dfrac{813.44}{41}\\\\F_h = 19.84\ inches[/tex]
Total fabric used for making wristband is : w = 358.16 inches.
Amount of fabric used for each person is :
[tex]F_w = \dfrac{358.16}{41}\\\\F_w = 8.74 \ inches[/tex]
Hence, this is the required solution.

Mary bought a car priced at $23,500. If the value of the car decreases every year by 9%, approximately what will be the value of the car after 10 years?
Answer:
$4626.548
Step-by-step explanation:
Given that :
Cost of car = $23,500
Value of car decreases by 9% every year
Value of car after 10 years =?
Using the formula :
A = p(1 + r/n)^nt
A = final amount
P = cost of car = principal
r = Depreciation = - 15%
t = number of years
A = 23500(1 + - 0.15/1)^10
A = 23500(0.85)^10
A = $4626.548
