Answer:
The correct answer is A.
Step-by-step explanation:
We are given:
The measure of two complementary angles are in the ratio 1 : 5
We know that the sum of complementary angles is 90 degree
Let the first angle be x
Let the other angle be 5x
Thus the equation we get:
x+5x = 90 degree
6x=90 degree
Divide both sides by 6
6x/6= 90/6
x= 15 degree
Now put the value of x in 5x
5x = 5(15)
= 75 degree
Thus the correct option is 15 degree, 75 degree....
Answer:
y = 2x + 1
Step-by-step explanation:
A line y = ax + b that is perpendicular to the other line y = (-1/2)x + 7
=> The product of 2 slopes of these 2 lines must be -1
=> a x (-1/2) = -1
=> a = 2
This line passes (2, 5) => 5 = 2*2 + b => 5 = 4 + b => b = 1
=> The equation of the line: y = 2x + 1
Hope this helps!
Answer:
FALSE
Step-by-step explanation:
If p could equal 10, 20, 30 or 40 lets put each of them in the expression 7.4p<=74
1. 7.4 times 10 equals 74 so that work✅
2. 7.4 times 20 equals 148 so that does not work X
3. 7.4 times 30 equals 222 so that does not work X
4. 7.4 times 40 equals 296 so that does not work X
Answer:
Approximately 4.58 minutes.
Step-by-step explanation:
The diameter of hose is in centimeters, that is 2.9 cm.
Velocity is in m/s that can be converted into cm/s.
Let the velocity be 'v'.
v = 3.3 m/s= 330 cm/s
The amount of water following through the cross sectional area of the hose is.
diameter = 2.9 cm
The cross sectional are of the hose is approximately . To volume of water that flows through the hose each second, multiply its velocity by the cross sectional area of the hose.
Volume/ second =
This is approximately . There are in one liter.
Total volume
To determine the time in seconds, divide the total volume by the volume per second.
t =
This is roughly 275 seconds.
We can convert 275 seconds into minutes.
t (mins) = minutes.
So it will take 4.58 minutes to fill the wading pool.
