In the diagram shown, m <AOC =124 and OA=10 cm. Which of the following is closest to the length of
arc ABC?

(1) 20.6
(2) 21.6
(3) 40.4
(4) 41.2
​

Answers

Answer 1

Answer:

(2) 21.6

Step-by-step explanation:

The segment OA is the radius of the circle

The arc of the complete circle is equivalent to its perimeter

perimeter = 2*π*radius = 2*π*10 = 62.83 cm

This arc is proportional to 360°. So, for 124°:

360°/124° = 62.83 cm/ x cm

x = 124*62.83/360

x = 21.6 cm

Without looking it up- what is -2317 - (-5294)?

Answers

Answer:

=2977

Step-by-step explanation:

-2317 - (-5294)

-2317 + 5294

2977

-2317 - (-5294)
you must make subtraction addition and then change the second number to its opposite. in this case, the opposite would be a positive number.
Since we are adding a negative and positive and the positive is a larger number, (if you find the absolute value of -2317) you would subtract these two.
This would give you: 2977.
you determine whether it’s positive or negative by looking at the largest absolute value of the number and taking that sign.
the largest absolute value is 5294 and right now they have a positive sign so you’d leave the number as is.
your answer being:
2977

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there

Answers

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

I think it’s x= 114 because it’s a straight line so it’s 180 so you subtract 66 from both sides so both 66s cancel so your let with 180 - 66 and it’s equal to 114 so there’s nothing to divided by so it’s just x= 114

If you put 34% over 100 multiply 34 and 450 then you will have 15,300. Then divide 15,300 and 100.

A can is a cylinder.

Surface area of a cylinder = 2πrh + 2πr²

Thus:

Amount of metal used to make the can = surface area of the can

r = 4/2 = 2 in.

h = 3 in.

Surface area = 2×π×2×3 + 2×π×2²

Alan used the expression StartFraction 5 over 9 EndFraction (F minus 32), where F is a temperature in degrees Fahrenheit, to convert a temperature from Fahrenheit to Celsius. He evaluated the expression as shown below and found that 45 degrees Fahrenheit was equivalent to –7 degrees Celsius.

StartFraction 5 over 9 EndFraction (F minus 32) = StartFraction 5 over 9 (45 minus 32) = 25 minus 32 = negative 7

What error did Alan make?
He substituted 45 for F instead of –7 and should have found the answer to be Negative 21 and two-thirds degrees Celsius.
He did not combine within the parentheses first before multiplying and should have found the answer to be 7 and StartFraction 2 over 9 EndFraction degrees Celsius.

The pharmacist has a 2.8 L bottle of cough syrup. If she fills a bottle that is 1,200 ml, how many ml of cough syrup does the pharmacist have left?

160 ml
400 ml
1,600 ml
4,000 ml

Answers

Answer: 1,600 ml

Step-by-step explanation:

You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).

2,800 ml - 1,200 ml = 1,600 ml

I hope this helps :)

Answer: 1,600 mL

Step-by-step explanation:

1. convert the 1,200 mL to L, which is 1.2 L.

2. Subtract that value from 2.8 L, equaling 1.6 L

3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.
