Answer:
a. 
b. 
Step-by-step explanation:
The formula for calculate the area of a rectangle is:
Where "l" is the lenght and "w" is the width
a. We know that the kitchen measures 3.75 meters by 4.2 meters; then we can say that:
Therefore, substituting these values into the formula, we get that the area of the kitchen is:
b. The area of the living room is one and a half times (1.5 times) that of the kitchen, this is:
Therefore, the total of the living room and the kitchen is:
Answer: B
Explanation: ONE triangle can be formed.
According to the triangle inequality theorem, the sum of any two sides must be greater or equal than the length of the third side.
Here, the sides are 1 m, 2 m, and 2m. 1m + 2m = 3m > 2m (theorem followed) 2m + 2m = 4m > 1m (theorem followed)
Since, the triangle inequality theorem is followed, Hence, ONE triangle can be formed.
Answer: I assume this ques was formatted like this originally. 4/10 = 2. If so the answer is 5 making the second fraction 2/5. Let me know if this is not the case. Hope this helps!
The answer is A, 2x represents two times the number minus 25% is 0.25 as a decimal answer.
Answer: C, D
<u>Explanation:</u>
Length: L = x + 3
width: x ≥ y + 2 ⇒ y ≤ x - 2
wheels: y
0.50(L * x) + 4(2.25y) ≤ 50
0.50(x + 3)(x) + 4(2.25y) ≤ 50
0.50(x² + 3x) + 9y ≤ 50
9y ≤ 50 - 0.50(x² + 3x)
<u>9y</u> ≤ <u>50 - 0.50x² - 1.5x</u>
÷9 ÷9
y ≤

15 per person is the rate
22 is the constant
y = 15x + 22
<em>divide that by the number of people (x) to get:</em>
y =
