Answer: 44 m
Step-by-step explanation:
Given
The area of the trapezium is [tex]A=480\ m^2[/tex]
Distance between parallel sides [tex]h=15\ m[/tex]
One of the parallel sides is [tex]20\ m[/tex]
Suppose the other parallel side is [tex]x[/tex]
The area of the trapezium is
[tex]A=\dfrac{1}{2}\times [\text{Sum of parallel sides}]\times h[/tex]
Put values
[tex]\Rightarrow 480=\dfrac{1}{2}\times [20+x]\times 15\\\\\Rightarrow 480\times 2=300+15x\\\Rightarrow 960-300=15x\\\Rightarrow x=44\ m[/tex]
What is the missing value?
54
30%
100%
?
Answer:
the missing value is 18.
Step-by-step explanation:
First i converted the percentage to a fraction which was 30% was 3/10 or 0.3 or 3 and 100% was 1 so i took those numbers with 54, 1, 3, and Solve for an unknown value x with this fractions calculator. Find the missing fraction variable in the proportion using cross multiplication to calculate the unknown variable x. Solve the proportion between 2 fractions and calculate the missing fraction variable in equal's.
For the equation
543=x1
The cross product is
54×1=3×x
Solving for x
x=54×13
and reducing
x=18
Solution by Proportion
Since the equation is an equality
If
3 ÷ 1 = 3
Then it is true that
54 ÷ x = 3
Solving for x
x = 54 ÷ 3
x = 18
(a) A company has 39 salespeople. A board member at the company asks for a list of the top 5
salespeople, ranked in order of effectiveness. How many such rankings are possible?
Answer:
69090840 possible rankings
Step-by-step explanation:
The number of possible ranking ordered in terms of effectiveness can be obtained using permutation
Number of salesperson = 39
Number of rank = 5
nPr = n! ÷ (n - r)!
nPr = 39P5
39P5 = 39! ÷ (39 - 5)!
39P5 = 39! ÷ 34!
39P5 = 39 * 38 * 37 * 36 * 35 = 69090840

4x - 5 + 2(x - 3) = 12x + 7
Step by step please and thank you
Answer:
x = -3
Step-by-step explanation:
4x - 5 + 2(x - 3) = 12x + 7
4x - 5 + 2x - 6 = 12x + 7
6x - 11 = 12x +7
6x - 12x = 7 + 11
-6x = 18
x = -3
The radius of the earth is 6378.1 km what is circumfrence of the earth in metres in standard form how many times can light encircle the earth per second
Answer:
Two things we need to remember:
Speed of light = c = 299,792,458 m / s
This means that the light in one second covers a distance of 299,792,458 m
And for a circle of radius R, the is:
C = 2*pi*R
where:
pi = 3.14
Then if the radius of the earth is 6,378.1 km, then the of the earth is:
C = 2*(3.14)*6,378.1 km = 40,054.468 km
And we know that 1 km = 1000m
Then the circumference of the earth is:
C = (40,054.468*1000) m = 40,054,468 m
Now we need to see how many times the light can encircle the earth per second. (we assume that the light can move in a circular path, this is not really accurate to the reality)
We know that in one second the light can cover a distance of: 299,792,458 m
And the circumference of the earth is: 40,054,468 m
The quotient between these two distances is the number of times that the light can encircle the earth:
N = (299,792,458 m)/(40,054,468 m) = 7.5
So light could encircle the earth 7.5 times per second.
You and your family go to dinner and you leave an 18% tip for the server. If the meal costs $52.50, how much should you leave for a tip?
Answer:
You should leave $9.45 for the tip!
Step-by-step explanation:
52.5 x 0.18 = 9.45
hope this helped! UwU
Answer:
You should leave a $9.45 tip.
Step-by-step explanation:
Here is a simple way to do this. Break it down into easy percentages.
$52.50 is a 100% tip.
$5.25 is a 10% tip.
$.525 is a 1% tip.
Multiply $.525 by 8 to get an 8% tip.
The answer to that will be $4.20.
Now add $4.20 and $5.25 to get an 18% tip.
Your answer is $9.45.

Show whether each value in the set {2,3,4} is a solution of the equation x + 2 = 6.
PLEASE HURRY. THIS IS DUE IN 7 MINUTES
Answer:
4
Step-by-step explanation:
Plug in each given value into the expression to see if it is true.
Set given: {2 , 3 , 4}
Equation given: x + 2 = 6
First, plug in 2 for x. When x = 2:
x + 2 = 6
(2) + 2 = 6
4 ≠ 6.
Next, plug in 3 for x. When x = 3:
x + 2 = 6
(3) + 2 =6
5 ≠ 6.
Finally, plug in 4 for x. When x = 4:
x + 2 = 6
(4) + 2 = 6
6 = 6 (True).
In the given set, only 4 complete the equation.

We just have to see what equals 22 added with 6 and 16+6=22 and 16/4=4
Answer:
x=4
Step-by-step explanation:
First, we need to get rid of the integers:
4x = 22-6
Now, we solve that part:
4x = 16
If 4x is 16, then what is x? To solve this, we divide each side of the equation by 4:
x=4

Karthik borrows 1200 from junaid for 2 years for 20% rate of interest how much karthik should play to compound annually
Answer:
1728
Step-by-step explanation:
1200 borrowed for 2 years at 20% compounded annually ;
Using the compound interest formula :
A = P(1 + r/n)^nt
P = 1200 = principal
Time, t = 2 years
Rate, r = 20% = 0.2
A = 1200(1 + 0.2)^2
A = 1200(1.2)^2
A = 1200 * 1.44
A = 1728
Final amount to be repayed = 1728

Answer:
Step-by-step explanation:
the area of a parallelogram is the same as a rectangle, well, uses the same formula. therefore it uses base × height.
for this equation we need to do 7.1 × 11.4
7.1 × 11.4 = 80.94
if you need to round the number to a whole number, it will be 81 because the first decimal digit is the number 9, and any decimal number 5 or up rounds up to the next number :D
good luck :)

A circular table top has a radius of 24 inches.
What is the area of the table top, to the nearest square inch? Use 3.14 for Pi.
75 in.2
151 in.2
1809 in.2
7235 in.2
Answer:
1809 in.2.
Step-by-step explanation:
So we know that the formula of a circle's area is r^2 * pi.
In this case, the radius is 24 inches. 24^2 = 576. They tell us to use 3.14 for pi.
576 * 3.14 = 1808.64.
The area is 1808.64, which rounds up to 1809 in.2.
Hope this helps!
Answer:

One year British columbia had 6149 police officers and a total population of 3282000 Nova scotia had 1542 police officers and a total population of 900000 which province had the greater number of people per police officer
Answer: Nova Scotia
Step-by-step explanation:
British Columbia people per police officer:
= Population number / no. Of policemen
= 3,282,000/6,149
= 534 people per policeman
Nova Scotia
= 900,000 / 1,542
= 584 people per policeman
A high-speed train travels at a speed of 200km/h. If the train sets off from Station A at 12 24 and reaches station B at 14 12, find the distance between the two stations.
Given:
Speed to train = 200km/h
The train sets off from Station A at 12:24.
Reaches station B at 14:12.
To find:
The distance between both stations.
Solution:
We have,
Speed to train = 200km/h
Time taken by the train to cover the distance between station A and station B is the difference between 14:12 and 12:24.
Time = 1 hr 48 min
Time = 1.8 hours [ 1 hr = 60 minutes]
Let d be the distance between both stations.
We know that,
[tex]Speed=\dfrac{Distance}{Time}[/tex]
[tex]200=\dfrac{d}{1.8}[/tex]
[tex]200\times 1.8=d[/tex]
[tex]360=d[/tex]
Therefore, the distance between the two stations is 360 km.
