A train travels 43 miles in 1/6 hour. How many miles does the train travel in 7 hours? (To form the unlock code, write your answer backward. For example: 2893 --> 3982)
Answer:
6081 (original 1806)
Step-by-step explanation:
to get from 1/6 to 7 you must multiply by 42
then you multiply 42 by 43
42 * 43 = 1806
the answer is 1806 but the unlock code is backwards so its 6081
Last year, the average number of absences in schools was 9 students per day. This year the average number is 6 students per day. What is the percent of decrease in student absences this year?
Answer:
The percent of decrease is 33.3... percent
Step-by-step explanation:
9 - 6 = 3
3 ÷ 9 = 0.3...
0.3... x 100 = 33.3...
The percent of decrease in student absences this year is 33.33%
What is percentage?The percentage is a fraction or a ratio in which the value of the whole denominator is always 100.
Given that the average number of absences in schools was 9 students per day.
This year the average number is 6 students per day.
We need to find the percent of decrease in student absences this year,
So, the percentage of decrease = 9 - 6 / 9 × 100%
= 1/3 × 100
= 33.33%
Hence the percent of decrease in student absences this year is 33.33%

PLEASE HELP!! 50 POINTS! 6TH GRADE MATH- picture- PLEASE EXPLAIN!
Answer:
59.6 ft²
Step-by-step explanation:
The surface area of the pillow is the total area of the net.
The net is made up of 3 rectangles and 2 congruent triangles.
Area of a rectangle = width × length
Area of a triangle = 1/2 × base × height
Rectangle 1 (left)
area = 4 × 5 = 20 ft²
Rectangle 2 (middle)
area = 4 × 5.4 = 21.6 ft²
Rectangle 3 (right)
area = 2 × 4 = 8 ft²
Triangle
area = 1/2 × 5 × 2 = 5 ft²
(Be careful here, as it is easy to use the wrong length for the base of the triangle. The base and height of the triangle are perpendicular, so at right angles to each other. Therefore, the base is 5ft and the height is 2ft)
Total area = rectangle 1 + rectangle 2 + rectangle 3 + 2 × triangle
= 20 + 21.6 + 8 + (2 × 5)
= 49.6 + 10
= 59.6 ft²

suppose 10% of the flights arriving at an airport arrive early, 60% arrive on time, and 30% arrive late. Valerie used the random number table to find the experimental probability that of 5 flights, at least 2 will arrive late. the digit 0 repersents flights arriving early. the digits 1,2,3,4,5, and 6 represents flights arriving on time. the digits 7,8 and 9 represent flights arriving late. Find the experimental probability that of 5 flights at least 2 will arrive late.
First, we need to have a random number table.
Next, we randomly choose numbers from the table and consider the first five digits.
After, the corresponding flight arrival is determined based on the given rules in the problem.
Then, the probability that at least 2 will arrive late is determined by taking the average.

Answer:
Vertical angles are congruent, so the
equation 3x-6 = 114 can be used to find x.
The value of x is 40.
Convince Me!
Why can you use an equation when solving for x in
the diagram?
You can use the eqution because they are equal to each other. When they are equal to each other, you can find x by using the equation to simplify and get x alone.

The distance from Charlotte to Asheville is about 120 miles. If R.C. has two hours to make the trip, but drives 50 mph for the first 60 miles, how fast must R.C. go on the second half of the trip to reach Asheville in time?
A. 70 mph
B. 75 mph
C. 77.2 mph
D. none of these
Answer:
B. 75 mph
Step-by-step explanation:
d - distance
v - velocity
t - time
d = 120 miles
t = 2 hrs
1st 60 miles :
[tex]v = \frac{d}{t} [/tex]
[tex]t = \frac{d}{v} [/tex]
[tex]t = \frac{60}{50} [/tex]
[tex]t = 1.2 \: hrs[/tex]
[tex]t = 1.2 \times 60[/tex]
[tex]t = 72 \: minutes[/tex]
2nd 60 miles:
It took 72 minutes for him to travel the first 60 miles. To get the remaining time:
[tex]t = 120 - 72[/tex]
[tex]t = 48 \: minutes[/tex]
[tex]t = 0.8 \: hrs[/tex]
For the Velocity:
[tex]v = \frac{d}{t} [/tex]
[tex]v = \frac{60}{0.8} [/tex]
[tex]v = 75 \: mph[/tex]

How do you do this I don't understand
Answer:
x = 6 units
Step-by-step explanation:
To solve this you can use Pythagorean Theorem;
A² + B² = C²
Where A and B are the legs of the triangle and C is the hypotenuse which always the diagonal line
So now that we know;
A = 8
B = x
C = 10
We can substitute and solve;
A² + B² = C²
(8)² + (x)² = (10)²
64 + (x)² = 100
(x)² = 36
x = √36
x = 6
Hope this helps!
