For the first one:

You take the number of plain chips and divide it by 3, then multiply by four. You do this because there is a 4 to 3 ratio of hot to plain chips.

42 / 3 = 14, 14 x 4 = 56.

Second one:

Birds (usually) have two wings for each beak. Why? I don't know, ask Darwin. There is a 2:1 (two to one) ratio of wings to beaks.

Third:

50 flaps per second, 60 seconds in a minute. 50 x 60 = 3000.

45,000 / 3000 = 15 minutes.

Fourth:

56 + 120 + 24 = 200

56 / 200 = 28% of the students ate pasta

A)46. Take 42 and divide it by 3. Then multiply 14 by 4.
b)2:1. There are 2 wings for every 1 beak on a bird.
c)15 minutes. multiply 50 times 60 and that's how many times it beats per minute. Then divide 45000 by that number and that's how many minutes it should take.
d) 28%. You have to add all the students together, and you get 200. Then you divide 56 by 200.

a circuit overloads at 1800 watts of electricity you plug a microwave oven that uses 1100 watts into the circuit write and solve
Bogdan [553]
Let w be the additional watts you can add on the circuit.

1100 + w < 1800 (write the inequality)
-1100 -1100 ( - 1100 from each side)

w < 700 (simplify)


ANSWER:
You can add up to 700 watts to the circuit, which means that you can also plug in the clock radio and the blender.


LOOK BACK:
You can check that your answer is correct by adding the numbers of watts used by the microwave oven, clock radio and blender.

1100 + 50 + 300 = 1450

The circuit will not overload because the total wattage is less than 1800 watts.

If fixed cost of 20 article is 500 and variable cost for each article is 40. Find the total cost function? Also ,find the total
Deffense [45]

Answer:

Cost function = 40a + 500

Cost of 90 articles = $4,100

Step-by-step explanation:

The fixed cost is $500 and it will.not change regardless of production level.

The Variable cost is $40 and increases by every additional unit produced.

Assume the number of articles produced is a.

Cost function would be:

Total cost = Variable cost * Number of articles + Fixed cost

TC = 40a + 500

Using this, the cost of 90 articles is:

= 40 * 90 + 500

= $4,100
