What is 2.54 as a mixed number?
What is 3.750 as a mixed number?

Answers

Answer 1
Answer: 2.54=2+0.54=2+(54)/(100)=2(54:2)/(100:2)=\boxed{2(27)/(50)}\n\n3.750=3.75=3+0.75=3+(75)/(100)=3(75:25)/(100:25)=\boxed{3(3)/(4)}
Answer 2
Answer: 2.54 is pronounced two and fifty four hundredths so u would write it exactly as u hear it. 2, and 52 over 100. So, 2.54 is 2 and 54/100. This can be simplified to 2 and 27/50. 3.750 is the same as 3.75 so it is pronounced three and seventy five hundredths. Same as the other example, this is 3 and 75/100. This can be simplified to 3 and 3/4 because both 75 and 100 can be divided by 25.

6) You have a bag of candy. You eat half of the candy after lunch and a quarterof what you have left after dinner. Now you have 3 pieces left. How many
candies did you start with?

Answers

Answer:

you started with 6 candies

Step-by-step explanation:

find the sum if 1/2 and 1/4 of the remaining half

1/2+1/4=3/4

therefore 3/4 of the candies has been eaten remaining 1/4 of the candies.

total fractions of candies =1

if 1/4 : 3

then 1: ?

if more, less divides

1÷1/4×3

1×4/1×3

12

there fore the total candies are 12 and since the question asked his much you started with, and you know you started with half of the total, find half of the total

1/2×12=6

What is the discriminant of the quadratic equation 3 - 4x = -6x^2-68
-56
76
88

Answers

Answer: B) -56

Step-by-step explanation:  In a quadratic equation, the discriminant helps tell you the number of real solutions and it is:

b^(2) -4ac

To calculate the discriminant of the given equation, we need to write it in the standard form (we equal it to zero):

6x^(2) -4x+3=0

here we can see that a=6;  b=-4; and c=3

so the discriminant would be:

(-4)^(2) -4*6*3=

16-72=-56
The discriminant is -56.

The discriminant is found using

b²-4ac, after the quadratic is in standard form.  First, we will add 6x² to both sides to write it in standard form:
3-4x=-6x²
3-4x+6x²=-6x²+6x²
6x²-4x+3=0

We can now see that b=-4, a=6 and c=3:

(-4)²-4(6)(3)
16-72
-56

Step-by-step explanation:

The distance from home plate to second base is about 127.3 ft.  1.  How would you find the distance between the bases.
2.  Estimate the distance between the bases to the nearest foot.
3.  When you hit home run how far do you run?

Answers

1. The distance between the bases is 37.3 feet.

2. The distance between the bases to the nearest foot is 37.

3. You ran 360 feet.

1. To find the distance between the bases, you would subtract the length of one base (typically 90 feet) from the total distance from home plate to second base. So, the distance between the bases would be 127.3 ft - 90 ft = 37.3 ft.

2. To estimate the distance between the bases to the nearest foot, you would round the calculated distance between the bases (37.3 ft) to the nearest whole number. In this case, it would be 37 feet.

3. When you hit a home run, you run around all the bases, including home plate. Therefore, to determine the distance you run when hitting a home run, you would add up the lengths of all the base paths. The total distance to run would be the sum of the distances from home plate to first base, first base to second base, second base to third base, and third base back to home plate. In a standard baseball field, each base path is typically 90 feet long, so the total distance to run would be 4 x 90 ft = 360 feet.
