Let

c-------> the number of chores

we know that

3+2c \geq 13 --------> inequality

Solve for c

3+2c \geq 13\\2c \geq 13-3\\ 2c\geq10 \\ c\geq5

therefore

<u>the answer is</u>

The minimum number of chores that Janie must do is 5\ chores

Answer:

  1. the range of f^-1(x) is {10, 20, 30}.

  2. the graph of f^-1(x) will include the point (0, 3)

  3. n = 8

Step-by-step explanation:

1. The domain of a function is the range of its inverse, and vice versa. The range of f^-1(x) is {10, 20, 30}.

__

2. See above. The domain and range are swapped between a function and its inverse. That means function point (3, 0) will correspond to inverse function point (0, 3).

__

3. The n-th term of an arithmetic sequence is given by ...

  an = a1 +d(n -1)

You are given a1 = 2, a12 = 211, so ...

  211 = 2 + d(12 -1)

  209/11 = d = 19 . . . . . solve the above equation for the common difference

Now, we can use the same equation to find n for an = 135.

  135 = 2 + 19(n -1)

  133/19 = n -1 . . . . . . . subtract 2, divide by 19

  7 +1 = n = 8 . . . . . . . . add 1

135 is the 8th term of the sequence.

In triangle ABC, (angle A) is a right angle and (m angle B) = 45deg.
Ratling [72]
We can use the ratios for special triangles (see the attachment below). We'll be using the 45-45-90 triangle. We notice that side BC is equal to x \sqrt{2}, and side AC (x using the special right triangle) is equal to 16. We can therefore say that side BC is equal to 16 \sqrt{2} ft

A baseball team played 154 regular season games. The ratio of the number of games they won to the number of games they lost was
ELEN [110]

Answer:

Number of games won = 110

Step-by-step explanation:

Given:

Total games played = 154

The ratio of number of games won to number of games lost = \frac{5}{2}

Solution:

Let the number of games won be = 5x

Thus, number of games lost = 2x

The total games played can be given as = 5x+2x=7x

Thus, we have:

7x=154

Dividing both sides by 7.

\frac{7x}{7}=\frac{154}{7}

∴ x=22

So, number of games won  = 5\times 22 = 110
