Matthew is paid $8.50 for each acre he mows on his grandparent's estate. He mows 50% of an acre in 3/5 of an hour.

Answers

Question

At the rate, how much will Mathew be paid for two hours of moving? Round to the nearest cent.

Answer:

exact answer =$19.83

rounded answer = $20

Step-by-step explanation:

3/5 = 0.6, so in 0.6 hours he can do 50% so in 2 hours that has 3 0.6 so 150% and the remaining time is 0.2 hours thats 1/3 of 0.6 so just divide 50% by 3 you'll get around 16.7% so in 2 hours he finished 166.7%

16.7% = 1/3 of 50% = 8.50 = 8.50/3 = 2.83

so 8.50 + 8.50 + 2.83 =

$19.83

How to solve inscribed angles

If it involves an Arc, the inscribed angle is 1/2 of the measure of the are across from it. If the figure inscribed in a quadrilateral, opposite angles are supplementary (when added together equals 180 degrees) This is all I know :)

Use the table below to answer the following question.2. Do the values in the table represent a linear function? If so, what is the function rule?
(1 point)
The values do not show a linear function.
Yes, the values show a linear function: y = x + 4.
Yes, the values show a linear function: y = 2x + 2.
Yes, the values show a linear function: y = 2x.

Answers

The values in the table do represent a linear function.

Y = 2X

Plug in values from the table

Jamar has a bag that contains apple chews, lemon chews, and peach chews. He performs an experiment. Jamar randomly removes a chew from the bag, records the result, and returns the chew to the bag. Jamar performs the experiment 59 times. The results are shown below: An apple chew was selected 53 times. A lemon chew was selected 3 times. A peach chew was selected 3 times. Based on these results, express the probability that the next chew Jamar removes from the bag will be apple chew as a decimal to the nearest hundredth.​

Answers

Answer:

the answer is 0.90

Step-by-step explanation:

Answer:

The probability that the next chew Jamar removes from the bag will be an apple chew is:

P(apple) = number of times an apple chew was selected / total number of experiments

P(apple) = 53 / 59

P(apple) ≈ 0.90

Rounded to the nearest hundredth, the probability that the next chew Jamar removes from the bag will be an apple chew is 0.90.

What does 1/4 of a can of coffee cost if 4 cans of coffee cost $1.60

Answers

We know that 4 cans of coffee cost $1.60. So, if we divide that number by 4, we get

4\text{ cans of coffee} = 1.60 \iff \frac{4\text{ cans of coffee}}{4} = (1.60)/(4) \iff 1 \text{ can of coffee} = 0.4

Now we can simply repeat this process again: if we divide both sides by 4, we get

1 \text{ can of coffee} = 0.4 \iff \frac{1 \text{ can of coffee}}{4} = (0.4)/(4) \iff (1)/(4)\text{ cans of coffee} = 0.1
