If 2 eggs with bacon cost 2.70, and 1 egg with bacon costs 1.80, that means that 1 egg costs 0.90, so when we subtract once more 0.90 we get the price of the bacon alone, which is in this case 0.90.
Answer: perceived lack of anonymity
Step-by-step explanation:
The source of bias that occurs when a group of students are asked to evaluate their teacher mid-quarter is a perceived lack of anonymity.
Perceived lack of anonymity occurs when the responder is afraid that if he or she gives an honest answer, it can end up affecting them negatively.
In this case, the students may be afraid that giving an honest opinion on the teacher will affect them.
M will represent Matt and J is Jackson. M-2.25=J. You minus the difference between them and show that it equals to Jacksons. A variable is a number in math that can vary.
Answer:
80 pieces of wire.
Step-by-step explanation:
It may not come out evenly. If there is a remainder, it won't matter. Just throw it away and go with the integer answer.
Change 3 3/4 to a decimal
3.75
Change the 25 foot roll to inches.
25 feet * 12 inches / foot = 300 inches.
Now how many pieces of wire do we get.
1 piece of wire/3.75 inches = x pieces of wire / 300 inches
3.75 * x = 300
3.75 * x / 3.75 = 300 / 3.75
x = 80
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
