Answer:
42 units^2.
Step-by-step explanation:
We are given that it is a rectangle so its area is the product of the length of adjacent sides.
Length of the horizontal line = 11 - 4 = 7 units ( from the first 2 points) and the length of an adjacent side is 9 - 3 = 6 units (from the second and third points).
Area = 7 * 6 = 42.
Answer:
Step-by-step explanation:
If we choose chairs having odd number in the row
no of chairs from which selection is made = 10
no of chairs to be selected = 5
no of ways = 10C₅
similarly if we choose hairs having even numbers only ,
similar to above , no of ways
= 10C₅
Total no of ways
= 2 x 10C₅
= 2 x 10 x 9 x 8 x 7 x 6 / 5 x 4x3 x 2 x 1
= 504 .
Answer:
t ≥ 1.5
Step-by-step explanation:
Lets take time for practicing the piano to be t
The number of hours to practice per week should be at least 6 hours
This is written as t ≥ 6
She already practiced 3 hours this week, thus the remaining hours to practice should be
t ≥ 3
The minimum remaining hours to practice for the remaining 2 days should be
t=3
If these hours are evenly divided, then in a single day she should practice
for t ≥ 1.5
The answer would be 2. As you can see on the point, you already have (-2,2) as a point. F(x) equals y in a sense. So when plugging in x into a function, you should get its respect y value. In the function graph, -2 yields 2. Therefore, your answer is 2.
Answer:
1199
Step-by-step explanation:
There are 22 terms in the sum:
23 + 26 + 29 + ... + 80 + 83 + 86 =
= (23 + 86) + (26 + 83) + ... + (53 + 56)
= 109 + 109 + ... + 109
= 11(109)
= 1199
