Answer: great adventure theme park is more expensive
Step-by-step explanation:
The temperature was recorded at the same time each day,
a)
Which temperature was the warmest?
b)
Which temperature was the coldest?
c)
How much colder was it on Thursday than on Saturday?
d)
On Sunday the temperature was 5°C lower than on Saturday.
What was the temperature on Sunday?
Answers
Answer:
a) The warmest temperature will be the one where the value of the temperature is the largest, in the table we can see that the largest temperature is 3°C on Saturday.
Then the largest temperature was on Saturday, and it was 3°C
b) Which temperature was the coldest?
Now we need to look at the smallest temperature (or the largest negative temperature). In the table we can see that the smallest temperature is -6°C on Friday.
Then the smallest temperature is -6°C.
c) On Thursday the temperature was -1°C
On Saturday the temperature was 3°C
The difference between the temperatures is:
-1°C - (3°C) = -4°C
This means that Thursday was -4°C colder than on Saturday.
d) On Sunday, the temperature was 5°C lower than on Saturday.
On Saturday the temperature was 3°C, then the temperature on Sunday is:
T = 3°C - 5°C = -2°C
The temperature on Sunday is -3°C.
Find 9079 + 1232 + 9786.

Jamal needs to purchase a countertop for his kitchen. Jamal measured the countertop as 5 ft. The actual measurement is 4.5 ft. What is Jamal’s percent error?
A) 5%
B) 11%
C) 45%
D) 50%
Answers
Answer:
percent error is 11.1% (which agrees with answer B)
Step-by-step explanation:
The discrepancy (difference) between the measurement and the real length was: 5 - 4.5 = 0.5 ft
Then the percent difference is calculated as:
(difference / real value) * 100 = ( 0.5 / 4.5ft ) * 100 = 11.1%

Michael drove from home to work at an average speed of 50 mph. His return trip home took 30 minutes longer because he could only drive at 40 mph. Find the distance from his home to his work. A. [3 pts) Define variables to represent the unknowns and setup the necessary equations to answer the question. B. [4 pts) Algebraically solve the equation you created and express your final answer using a complete sentence and appropriate units. (You will not receive full credit if a trial and error method is used in place of an algebraic method.)
Answers
Answer:
100 miles
Step-by-step explanation:
Given :
To work :
speed = 50mph
Let time taken = x
From work :
speed = 40mph
30 minutes = 30/60 = 0.5
Time taken = x + 0.5
Distance from home to work :
Distance = speed * time
To work distance = from work distance
This can be algebraically expressed as :
50 * x = 40(x + 0.5)
50x = 40x + 20
50x - 40x = 20
10x = 20
x = 20/10
x = 2
Hence,
Distance = 50 * 2 = 100
The the distance from home to work = 100 miles
The distance from Michael home to work is 100 miles
SpeedSpeed is the ratio of the total distance travelled to the total time taken. It is given by:
Speed = distance / time
Let d represent the distance from Michael home to work. Hence:
50 = d/tt = d / 50He took 30 minutes (0.5 hours) longer when driving at 40 mph, hence:
40 = d/(t + 0.5)t = (d - 20)/40d/50 = (d - 20) / 40
40d = 50d - 1000
10d = 1000
d = 100 miles
The distance from Michael home to work is 100 miles

Answer:
(2/5)√5
Step-by-step explanation:
from the sine rule (see attached for reference), we can construct the following relationship
12/sinθ = (6√5) / sin 90°
recall that sin 90° = 1, hence our equation becomes:
12/sinθ = (6√5) / 1
12/sinθ = (6√5) (rearranging)
12 ÷ (6√5) = sin θ
sin θ = 12 / (6√5)
sin θ = 2 / √5 (moving radical to numerator by multiplying by √5/√5)
= 2 / √5 x √5/√5
= 2√5 / 5
= (2/5)√5

Mary has 200ml of hand sanitizer that is 15% alcohol. She mixes it with 200ml of a
hand sanitizer that is x% alcohol,
How many milliliters of water is in the resulting mixture of hand sanitizers?
Answers
Answer:
(370-2x)ml
Step-by-step explanation:
We are given that
In first hand sanitizer
Total solution=200ml
Alcohol=15% of 200ml
Alcohol=[tex]\frac{15}{100}\times 200=30ml[/tex]
In second hand sanitizer
Solution=200 ml
Alcohol=x% of 200 ml
Alcohol=[tex]\frac{x}{100}\times 200=2x ml[/tex]
We have to find the water in the resulting mixture of hand sanitizers.
Total solution of two hand sanitizers=200+200=400ml
Total alcohol in two hand sanitizers=(30+2x)ml
Water in two hand sanitizers=400-(30+2x) ml
Water in two hand sanitizers=400-30-2x ml
Water in two hand sanitizers=(370-2x)ml
Hence, water in the resulting mixture of hand sanitizers=(370-2x)ml

24.6 Nm north67.7 Nm westStep-by-step explanation:
In x-y coordinates, the direction is 70° CCW from 90° (north), so is 160° from the +x axis. In 4 hours at 18 Nm/h, the ship will travel 4×18 Nm = 72 Nm.
The coordinates in the x-y plane can be found to be ...
72(cos(160°), sin(160°)) ≈ (-67.7, 24.6)
The ship traveled 67.7 nautical miles west and 24.6 nautical miles north from the port.

At a basketball game, a team made 53 successful shots. They were a combination of 1- and
2-point shots. The team scored 90 points in all. Write and solve a system of equations to find the
number of each type of shot.
There were
2-point shots and 1-point shots.
Answers
Answer:
Let x be the number of 1 point shots, and y be the number of 2 point shots.
So the system is:
x+y=53
1x+2y=90
We can solve this system by substitution.
x+y=53, x=53-y
x+2y=90
53-y+2y=90
53+y=90
y=37
That means, the team made 37 two point shots.
If the team made 37 two point shots, the team scored 37 x 2, or 74 points from 2 point shots, meaning that it made 16 one point shots.
So the correct answer is: 16 one point shots, 37 two point shots.
