Step-by-step explanation:
b = √c2 - a2
= √102 - 52
= √75
= 8.66025 = 5√3
Answer: D
Step-by-step explanation:
Using Pythagoras’ theorem
H^2= O^2 + A^2
H= 10
O= 5
A= x
A^2= H^2 - O^2
x^2= 10^2 - 5^2
x^2= 100 - 25
x^2= 75
x= 75^(1/2)
x= 5(3^(1/2))
x= 5 √3

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
Answers
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.

pleaseee CAN YALL HALP ME
Answers
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

A=62 degrees
B= 45 degrees
C=45 degrees

(1/2y - 50)(3/5y + 10)
Answers
Answer:
-24 7/10y - 500
Step-by-step explanation:
Use the distributive property to solve this question.
Distribute the 1/2y and the -50 over the next bracket.
(1/2y - 50)(3/5y + 10) = 1/2y(3/5y) + 1/2y(10) + - 50(3/5y) + - 50(10)
= 3/10y + 5y - 30y - 500

How many gallons each of 20% alcohol and 10% alcohol should be mixed to obtain 10gal of 11% alcohol?
Answers
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

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.
Answers
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
