Answer:

The answer for number 4 is 40:1

Step-by-step explanation:

The answer is 40:1 because we have to change values to whole numbers.

Convert the whole number 20 to a fraction with 1 in the denominator.

When we do that, we should then have:

20 : 1/2 = 20/1 : 1/2

We also have to convert fractions to integers by eliminating the denominators.

Our two fractions have unlike denominators so we find the Least Common Denominator and rewrite our fractions as necessary with the common denominator  

LCD(20/1, 1/2) = 2

We now have:

20 : 1/2 = 40/2 : 1/2

Our two fractions now have common denominators so we can multiply both by 2 to eliminate the denominators.

We then have:

20 : 1/2 = 40 : 1

Try to reduce the ratio further with the greatest common factor (GCF).  

The GCF of 40 and 1 is 1

Divide both terms by the GCF, 1:

40 ÷ 1 = 40

1 ÷ 1 = 1  

The ratio 40 : 1 cannot be reduced further by dividing both terms by the GCF = 1 :  

Therefore:

20 : 1/2 = 40 : 1 is the answer.

*PLEASE HELP MEEEEEE* You throw a dart at the board shown. Your dart is equally likely to hit any point inside the square board.
yawa3891 [41]

Answer:

19.63%

Step-by-step explanation:

The probability of scoring 8 points is the probability of getting a dart into the green circle.

That probability is equivalent to the area of the circle divided by the total area of the square board.

The area of the circle according to A=\pi*r^2, is 25\pi cm squared

The area of the whole square board is one side squared: 20 squared = 400 cm squared

The probability is therefore equal to 25\pi/400 = \pi/16=0.19634=19.63%%

A triangle has one angle that measures 40 and another that measures 38. What is the measure of the triangles third angle
mr_godi [17]

Answer:

102°

Step-by-step explanation:

that's the answer because 40+ 38 = 78. then 180- 78 = 102. Remember that in tringles, all three angles should add up to 180°

james tailoring service charges a flat rate of $20 and charges an additional $12 per hour when making a tailored suit. how much
jeka94

Answer:

It will cost Mr. Smith $68 to make his suit.

Step-by-step explanation:

Since the charge $12 per hour, and it takes 4 hours to make the suit, then we need to multiply 12 by 4.

12 × 4 = 48

Now we need to add the flat rate since that is the initial charge for service.

48 + 20 = 68

This means it will cost Mr. Smith a total of $68 for his suit.
