0 $25,001.00
1 $25,000.95
2 $25,000.90
3 $25,000.86
I graphed the function on the graph below and found the values of y for each value of x.
*My graph showed that the initial value of the printer was $25,001.00, instead of $25,000.00*
Answer:
All real numbers
Step-by-step explanation:
3(5x - 4) < 15x
~Distribute left side
15x - 12 < 15x
~Subtract 15x to both sides
-12 < 0
Best of Luck!
Answer:
The area of the rectangle is 1222 units²
Step-by-step explanation:
The formula of the perimeter of a rectangle is P = 2(L + W), where L is its length and W is its width
The formula of the area of a rectangle is A = L × W
∵ The length of a rectangle is 5 less than twice the width
- Assume that the width of the rectangle is x units and multiply
x by 2 and subtract 5 from the product to find its length
∴ W = x
∴ L = 2x - 5
- Use the formula of the perimeter above to find its perimeter
∵ P = 2(2x - 5 + x)
∴ P = 2(3x - 5)
- Multiply the bracket by 2
∴ P = 6x - 10
∵ The perimeter of the rectangle is 146 units
∴ P = 146
- Equate the two expression of P
∴ 6x - 10 = 146
- Add 10 to both sides
∴ 6x = 156
- Divide both sides by 6
∴ x = 26
Substitute the value of x in W and L expressions
∴ W = 26 units
∴ L = 2(26) - 5 = 52 - 5
∴ L = 47 units
Now use the formula of the area to find the area of the rectangle
∵ A = 47 × 26
∴ A = 1222 units²
∴ The area of the rectangle is 1222 units²
Question B) you want to take 0.75, divide it to both sides and you get m= 21 0.75m=15.75 m = 21 ___________ = 0.75
Answer: The actual height of train = 4.896 meters.
Step-by-step explanation:
Since we have given that
Lina has a scale model of a modern train
Model is created at a scale is given by
1:48
Height of the model train = 102 millimeters
We need to find the actual height of the train.
Since there is direct variation between model and actual height of the train.
According to question,
Hence, the actual height of train = 4.896 meters.
