Answer:
1/13 or 7.69%
Step-by-step explanation:
A standard 52 card deck has 4 queens. So the probability of being dealt a queen is:
P(Queen) = 4/52
= 1/13
The probability is 1/13. To find the percent, divide 1÷13 and then times by 100.
1÷13 = 0.0769
0.0769× 100 = 7.69
This is 7.69%
12 grams.
If it’s 25% less, that’s the same as 1/4 less.
3/4 of 16 is 12.
Answer:
Chukwu's share is of $57.
Step-by-step explanation:
This question is solved by a system of equations.
I am going to say that:
Chukwu's share is x.
Abdul's share is y.
Kunle's share is z.
Chukwu, Abdul and kunle are to share $142
This means that 
Abdul gets $11.00 less than Chukwu
This means that:
$7.00 more than Kunle.
This means that:
So
How much is Chukwu's share?
We want to find x, so:
Chukwu's share is of $57.
Answer: the height of the flagpole is 21 ft
Step-by-step explanation:
Since the angle of elevation to the top of the flagpole is 40°, a right angle triangle is formed. The height of the flagpole represents the opposite side of the right angle triangle. Your distance from the base of the flagpole represents the adjacent side of the right angle triangle. Therefore, to determine the height of the flagpole, x ,we would apply the tangent trigonometric ratio which is expressed as
Tan θ = opposite side/adjacent side
Tan 40 = x/25
x = 25tan40 = 25 × 0.8391
x = 20.98
x = 21.0 ft to the nearest tenth.
