63 students choose to attend one of three after school activities: football, tennis or running.
There are 24 boys.
20 students choose football, of which 12 are girls.
17 students choose tennis.
22 girls choose running.
A student is selected at random.
What is the probability this student chose running?
Give your answer in its simplest form.
Answer:
the probability of the student chose running is 26 ÷ 63
Step-by-step explanation:
The computation of the probability of the student chose running is shown below:
= (Total students - football selected - tennis selected) ÷ (Total students)
= (63 - 20 - 17) ÷ 63
= 26 ÷ 63
Hence, the probability of the student chose running is 26 ÷ 63

How many gallons each of 20% alcohol and 10% alcohol should be mixed to obtain 10gal of 11% alcohol?
Answer:
20% alcohol = 1 gal
10% alcohol = 9 gal
Step-by-step explanation:
Let
x = 20% alcohol
y = 10% alcohol
x + y = 10 (1)
0.20x + 0.10y = 10*0.11
0.20x + 0.10y = 1.1 (2)
From (1)
x = 10 - y
Substitute x = 10 - y into (2)
0.20x + 0.10y = 1.1
0.20(10 - y) + 0.10y = 1.1
2 - 0.20y + 0.10y = 1.1
- 0.20y + 0.10y = 1.1 - 2
-0.10y = -0.9
y = -0.9/-0.10
y = 9 gal
substitute y = 9 into (1)
x + y = 10
x + 9 = 10
x = 10 - 9
x = 1 gal
20% alcohol = 1 gal
10% alcohol = 9 gal

a cruise ship travels at a constant speed. in 3 hours,the ship travels 72 nautical miles if the ship continues to travel at the same rate, how far would it travel in 11 hours
Based on the speed of the ship, after 11 hours, it would have travelled a distance of 264 nautical miles.
First find the speed of the ship:
= Distance / Time
= 72 / 3
= 24 nautical miles per hour
The distance in 11 hours is therefore:
= Time x Speed
= 11 x 24
= 264 nautical miles.
In conclusion, the ship would have travelled 264 nautical miles.

Evaluate the expression 6 + 4 x {3+7}.
Answer:
46
Step-by-step explanation:
6 + 4 x {3+7} [B.O.D.M.A.S rule] (First bracket)
= 6 + 4 × 10. (Then Multiplication)
= 6 + 40. ( At last addition)
= 46 (Ans)
The simplified value of the expression 6 + 4 × {3 + 7} is 100.
What is PEMDAS rule?PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.
Given, An expression 6 + 4 × {3 + 7}.
First, we'll add 6 and 4 as 3 and 7 are inside curly brackets,
not in parentheses.
Therefore,
6 + 4 × {3 + 7}.
= 10 × {3 + 7}.
Now, we can either distribute the terms or take the addition and multiply.
= 10 × 10.
= 100.

(2) Explain how the product of 3 and 65 could be used to find (0.03) - (0.65).*
Answer:
See Explanation
Step-by-step explanation:
Required
Explain how 3 * 65 could be used for (0.03) * (0.65)
0.03 is to 2 decimal places and 0.65 is also to 2 decimal places
In total, we have: [tex]2 + 2 = 4[/tex]
So, to get (0.03) * (0.65) from 3 * 65.
Simply calculate the product: 3 * 65
Then divide by 10 to the power of the sum of the decimal places i.e. 4
This is shown below
(0.03) * (0.65)
Express as fraction
[tex](0.03) * (0.65) = \frac{3}{100} * \frac{65}{100}[/tex]
[tex](0.03) * (0.65) = \frac{3*65}{100*100}[/tex]
[tex](0.03) * (0.65) = \frac{3*65}{10^2*10^2}[/tex]
[tex](0.03) * (0.65) = \frac{3*65}{10^4}[/tex]

Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
a = 180 - (90 + 28) = 180 - 118 = 62
b = a = 62 ( vertically opposite angles )
c = 180 - (90 + 62) = 180 - 152 = 28
Since a = b = 62 and c = 28
Then the triangles are similar by the AA postulate
Answer:
A=62 degrees
B= 45 degrees
C=45 degrees

The diagonals of square DEFG intersect at H. Given that EH = 5, find the indicated measure
Answer:
3. m<GHF= 90 degrees
4. m<DGH= 45 degrees
5. HF=5
6. DE=50
Step-by-step explanation:
3. The measure of angle DGF and EFG are 45 degrees each and 45+45 is 90 degrees. When you subtract 90 from 180, you get 90.
4. A square is also a rectangle and a rectangle has four right angles and it is a rhombus and the diagonals bisect the angles. This means that angle DGH is half of angle DGF and 90/2=45.
5. The diagonals of a square are congruent so it is also 5.
6. You use the Pythagorean Theorem and 5^2 + 5^2=50
The diagonals of square DEFG intersect at H. The measure of the following option; 3. m∠GHF= 90 degrees. 4. m∠DGH= 45 degrees 5. HF=5 6. DE=50
What is the property of a square?That rectangle whose all sides are equal is called a square.
A square is always a rectangle, parallelogram, a rhombus, and a quadrilateral but its reverse statement may or may not be true.
(ie it is not always necessary that a rectangle is a square or a parallelogram is a square or a rhombus is a square).
The diagonals of square DEFG intersect at H.
Given that EH = 5, we need to find the measure of the following option;
3. The measure of ∠DGF and ∠EFG are 45 degrees each .
The sum of the angle of the bisector of diagonal 45 + 45 = 90 degrees.
When you subtract 90 from 180, you get 90.
4. A square is also a rectangle and a rectangle has four right angles and it is a rhombus and the diagonals bisect the angles.
This means that ∠DGH is half of ∠DGF
90/2 = 45.
5. The diagonals of a square are congruent so HF is 5.
