An inequality can be formed by simply translating the problem statement to numerical expressions.
From the problem we know that

added with

hours should be equal or greater than

(helpful insight from the keyword "at least"). Therefore, it's inequality would look like:

(>= is used instead of ≥ for constraints in formatting)
The inequality above best models the situation.
For this case we have to by definition:
1 kilojoule equals 0.239006 kilocalorie.
1 kilocalorie equals 1000 calories
Then, if we have:
Now:

Answer:

Question 11a)
We are given side BC equals to side CE and angle CBA equals to angle CED
We also know that angle ACB equals to angle ECD are equal (opposite angles properties)
We have enough information to deduce that triangle ABC and triangle CDE are equal by postulate Angle-Side-Angle (ASA)
---------------------------------------------------------------------------------------------------------------
Question 11b)
We are given side AB equal to side ED, side BC equals to side EF, and side AC equals to side DF
We have enough information to deduce that triangle ABC and triangle DEF congruent by postulate Side-Side-Side (SSS)
----------------------------------------------------------------------------------------------------------------
Question 11c)
We are given side AC equals to side DF, angle ABC equals to angle DEF, and angle BAC equals to angle EDF
We have enough information to deduce that triangle ABC congruent to triangle DEF by postulate Angle-Side-Angle (ASA)
-----------------------------------------------------------------------------------------------------------------
Question 11d)
We do not have enough information to tell whether this shape congruent or not
Hello!
<h2>Answer: </h2>
23. 138 people voted for Nyemi, 69 people voted for Luke, and 23 people voted for Natalie.
24. Reina did not ride 11/16 of the rides.
<h2>
Explanation:</h2>
23:
3 ÷ 5 = 0.6
230 × 0.6 = 138
230 × 0.3 = 69
230 × 0.1 = 23
24:
We know that Alberto rode 5/8 of the rides at the park, and Reina rode half of this.
5/8 × 1/2 = 5/16
16 - 5 = 11
