A rectangular table is two times as long as it is wide. If the area is 50 ft2, find the length and the width of the table.
Answer:
length = 10ft
breadth = 5ft
Step-by-step explanation:
Given,
Let breadth be x.
According to the question,
length = 2x
Area = 50ft^2
we know that,
Area of rectangle ( A) = l × b
or, x × 2x = 50 ft^2
or, 2x^2 = 50ft^2
or, x^2 = 50ft^2/2
or, x^2 = 25ft^2
or, x = 5 ft
Now,
2x = 2×5ft =10ft
Therefore, length is 10ft and breadth is 5ft.

Calculate the average speed between 0 s and 20 s
Answer:
2 m/s
Step-by-step explanation:
Notice that the slope of the time period from 0s to 20s is linear. This means we can simply look at the distance traveled over the amount of time. So the distance and time both start at 0. At 20s, the distance is 40m.
So we can say the following to find the slope:
(40m - 0m) / (20s - 0s) == 40m / 20s == 2 m/s
Hence, the average speed between 0s and 20s is 2m/s.

Answer:
3.6 miles
Step-by-step explanation:
since his house is 8 inches away and 2 inches =0.9miles
we just need to multiply. Divide 8 by 2 .
4× 9 = 36 so just add the decimal
0.9× 4= 3.6 miles

A builder is building 5 new homes. Each home has a foyer measuring 9 feet by 18 feet. Laminate flooring for each foyer costs $26.91 per square yard. What is the cost of the laminate floors for the foyers in all 5 homes?
Answer: $2421.90
Step-by-step explanation:
Since a yard is 3 feet, we can say the foyer is 3 yards by 6 yards (9 feet is 3 yards and 18 feet is 6). The area of a square is x*y, so the area of each floor is 3*6 = 18 square yards. Since there are 5 homes, there are 5 * 18 = 90 total square yards to laminate. That means that the total cost is 90 * 26.91 = $2421.90.
The total cost for the foyer for the 5 homes is $ 2421.9.
Given that,
A builder is building 5 new homes. Each home has a foyer measuring 9 feet by 18 feet. Laminate flooring for each foyer costs $26.91 per square yard. What is the cost of the laminate floors for the foyers in all 5 homes is to be determined.
In mathematics, it deals with numbers of operations according to the statements.
Here,
1 yard = 3 feet
Now
The measure of foyer = 9 feet x 18 feet = 9 /3 yard x 18 / 3 yard.
Area of the foyer = 3 x 6
= 18-yard square
Area of the foyer of 5 homes = 5 * 18
= 90-yard square,
The total cost of a foyer for 5 homes = 90 * 26.91
= $2,421.9
Thus, the total cost for the foyer for the 5 homes is $ 2421.9.

1. In how many ways can a committee of eight people to be formed from a group of 6 male, 5 female and 4 students if there are no restrictions, as all members are eligible?
Answer:
The number of ways is 6435
Step-by-step explanation:
Given
[tex]Male = 6[/tex]
[tex]Female = 5[/tex]
[tex]Students = 4[/tex]
Required
Number of ways a group of 8 can be formed
Here, I'll assume each category of people are distinct:
Hence;
[tex]Total = Male + Female + Students[/tex]
[tex]Total = 6 + 5 + 4[/tex]
[tex]Total = 15[/tex]
Number of ways is then calculated as follows:
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
Where
[tex]n = 15\ and\ r = 8[/tex]
So, we have:
[tex]^{15}C_8 = \frac{15!}{(15 - 8)!8!}[/tex]
[tex]^{15}C_8 = \frac{15!}{7! * 8!}[/tex]
[tex]^{15}C_8 = \frac{15 * 14 * 13 * 12 * 11 * 10 * 9 * 8!}{7!8!}[/tex]
[tex]^{15}C_8 = \frac{15 * 14 * 13 * 12 * 11 * 10 * 9}{7!}[/tex]
[tex]^{15}C_8 = \frac{15 * 14 * 13 * 12 * 11 * 10 * 9}{7 * 6 *5 * 4 * 3 * 2 * 1}[/tex]
[tex]^{15}C_8 = \frac{32432400}{5040}[/tex]
[tex]^{15}C_8 = 6435[/tex]
Hence, the number of ways is 6435
327.8 in scientific notation
Answer:
3.278 * 10 ^ 2
Step-by-step explanation:
To change a number to scientific notation you:
Move the decimal point to the left to make the number have 1 number before the decimal point.
From there you multiply by 10 to the power 2 the number of decimal points you moved.
So the answer is 3.278 * 10^2

Which line is perpendicular to a line that has a slope of Negative one-third? line MN line AB line EF line JK
Answer:
The answer is line EF, C is the correct answer!
Step-by-step explanation:
Just took the assignment. Maybe this will help you with your other problems with slopes and angles. If you have any more questions for me, I'll answer them! :D
The perpendicular line is line EF.
What is slope?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane. Calculating the slope of a line is similar to finding the slope between two different points. In general, to find the slope of a line, we need to have the values of any two different coordinates on the line.
Slope = m = tan θ
m = (y2 - y1)/(x2 - x1)
Given:
slope = -1/3
then, the perpendicular line will have the slope = 3
Now, from the figure the line line represent the slope 3 is line EF
As, (0, -3) and (2, 3)
slope = 3+3 / 2-0
slope= 6/2
slope= 3
Hence, the perpendicular line is line EF.
