Hi,
First calculate how much chocolate for 1 dollar.
\frac{2}{3} = 0.67 \\ 0.67 \div 5 = 0.134
Then multiply by four to get amount of chocolate for four dollars.
0.134 \times 4 = 0.536
Answer: 0.536
Hope this helps.
Answer:
Domain: (-4, ∞)
Range: (-∞,∞)
Step-by-step explanation:
Domain is all of your possible x values and range is all of the possible y values. I may have wrote the brackets wrong but the values are wright.
Answer:
The width is 50 yards and the length is 141 yards.
Step-by-step explanation:
Let's call: L the length of the field and W the width of the field.
From the sentence, the perimeter of the rectangular playing field is 382 yards we can formulate the following equation:
2L + 2W = 382
Because the perimeter of a rectangle is the sum of two times the length with two times the width.
Then, from the sentence, the length of the field is 9 yards less than triple the width, we can formulate the following equation:
L = 3W - 9
So, replacing this last equation on the first one and solving for W, we get:
2L + 2W = 382
2(3W - 9) + 2W = 382
6W -18 +2W = 382
8W - 18 = 382
8W = 382 + 18
8W = 400
W = 400/8
W = 50
Replacing W by 50 on the following equation, we get:
L = 3W - 9
L = 3(50) - 9
L = 141
So, the width of the rectangular field is 50 yards and the length is 141 yards.
3.10+1.40= 4.50 nearest tenth
