Answer:
1. AB Is a tangent
2. AB is not a tangent
Explanation:
1. In the given figure
9.7^2 = 7.2^2 + 6.5^2
94.09 = 51.84+42.25
94.09 = 94.09
Hence, angle BAC is 90 degree.
Now any line that touches the circle at one point only and forms a 90 angle with the radius is a tangent
2. In the second figure
22^2 is not equal to 12^2 + 16^2
hence, AB is not a tangent
Answer:
A. Increase in the demand of computers
Explanation:
In economics, we understand that more demand translates to more supply and vice versa.
Also, it should be noted that the current generation of computer are made from computer chips.
So, the increase in the supply of computer chips (as stated in the question) is a function of an increase in the demand of computers.
Hence, option A answers the question.
How long was each sprinkler used is 30 hours.
<h3>How long was each sprinkler used </h3>
Let x represent how long each sprinkler was used
Hence:
40(x)+15(55-x)=1575
40x+825-15x=1575
Collect like terms
40x+-15x=1575-825
25x=750
Divide both side by 25x
x=750/25
x=30 hours
Therefore the Jenkins used the sprinklers for 30 hours while Green's used it for 25.
The complete question is:
The Jenkins family and the Moore family each used their sprinklers last summer. The water output rate for the Jenkins family's sprinkler was 40l per hour. The water output rate for the Moore family's sprinkler was per 15l hour. The families used their sprinklers for a combined total of 55 hours, resulting in a total water output 1575 of .
