Answer:

Mixed number: 8.72=8 72/100

Improper fraction: 8.72= 872/100

Step-by-step explanation:

8 is in the ones place, 7 is in the tenths place, and 2 is in the hundreths place, which makes 8.72. In fractions, that would be 8 wholes, and 72/100, which is 8 72/100. After that, you can turn it into an improper fraction by doing 8x100, which is 800, then you add 72, which is 872. That makes 872 the numerator, and 100 the denominator, which makes 872/100.

Answer:

Step-by-step explanation:

So at 55 miles per hour you go 12 miles in a little over 13 minutes.

.

Hope this helps you to understand the problem and how to use the formula to solve it.

Distance = Speed * Time

.

You might be able to understand this by thinking, "If I go at 60 miles per hour for 2 hours,

how far do I travel?" The answer is:

.

Distance = 60 miles per hour* 2 hours = 120 miles

.

In the problem you are told that the distance to be covered is 12 miles. The speed is 55 miles

per hour. Put these into the equation and you get:

.

12 miles = 55 miles per hour * Time

.

You can then solve for the Time by dividing both sides of this equation by 55 to get:

.

12/55 = Time

.

So it takes 12/55 hours to go 12 miles. The fraction 12/55 converts to a decimal by dividing

55 into 12 to get 0.218181818 of an hour. Since an hour has 60 minutes, you can convert

the answer to minutes by multiplying 60 by 0.218181818 to get about 13.09 minutes.

Answer & Step-by-step explanation:

A = 60 ft

C = 12

D = 1/2 of C

1/2 of 12 = 6

Step-by-step explanation:

1. To figure this out, you need to first convert the percentage to a decimal. To do this, you move the decimal two places back. 75.0% -> 0.75

40 * 0.75 = 30 students are present, because 75% of 40 is 30

40 - 30 = 10 students are absent, because 30 students are present.

2. To figure this out, you must do the same thing you did for number 1 above. It would look like this: 80% -> .80

250 * 0.8 = 200 euros - not sure if that's what it is but that is what I'm going with - is what she spent, because 80% of 250 is 200

250 - 200 = 50 is what she saved.

Answer:

c=2

Step-by-step explanation:

translation:

5x2-3x2=c2

10-6=4

4=c2

4/2=c2/2=c=2

When a = 5 and b = 3, the value of c is 4, based on the equation [tex]a^2 - b^2 = c^2[/tex].

Given the equation [tex]a^2 - b^2 = c^2[/tex] and the values a = 5 and b = 3, we can substitute these values into the equation and solve for c.

Substituting a = 5 and b = 3:

[tex](5)^2 - (3)^2 = c^2\\\\25 - 9 = c^2\\\\16 = c^2[/tex]

Taking the square root of both sides:

c = √16

c = 4

Therefore, when a = 5 and b = 3, the value of c is 4.

The number of hours Jeremy spent in the air is 16 hours.

He flew 8 times last week for work.

Each flight was two hours long.

Therefore, each flight, he spends two hours in the air.

Now he took this two hours flight for 8 times.

Therefore, the number of hours he spend in the air can be calculated as follows:

number of hours spent in the air = 8 × 2

number of hours spent in the air = 16 hours

Therefore, he spent 16 hours in the air.

Answer: (x+2)^2 -11

Step-by-step explanation:

X^2 +4x -7

Half the middle term, add it to x and put them into a bracket and square it

(X+2) ^2 -7

Square the second term to get 4 and then take that away from 7. (We do this because if we had the extra 4, our answer when’s we multiplied out of the brackets wouldn’t be x^2 +4x -7.)

(X+2)^2 -7 -4

Now simplify the whole numbers outside the bracket

(X+2) ^2 -11

4, 5, 6, 7 & 8 are exterior angles.

Answer:

See answers below.

Exterior angles are angles that form a linear pair with an angle of a triangle.

Remote interiors in a triangle are the angles that are not adjacent to an exterior angle of the triangle (meaning are not connected to the exterior angle)

A. Exterior angles are ∠8, ∠7, ∠5,  ∠4, and ∠6

B.   Remote interiors angles are :

      Looking at ∠6, the remote interior angles are ∠1 and ∠2

      Looking at ∠8, the remote interior angles are  ∠1 and ∠2

      Looking at  ∠5, the remote interion angles are ∠1 and ∠3

Given info:- Evaluate: [(5/6 + 2/3) - (3/4 + 1/12)] and find the Evaluated form = ?

Solution:-

Given fractional expression: [(5/6 + 2/3) - (3/4 + 1/12)]

Take the LCM of denominator 3 and 6 is 6.

Again take the LCM of denominator 4 and 12 is 12.

so,

⟼ [(5+4)/6 - (9+1)/12]

⟼ [9/6 - 10/12]

Now, take the LCM of the denominator 9 and 12 is 36.

⟼ [(54-30)/36]

Now, reduce the fraction by extracting and cancaling out with 2.

⟼ [24÷2/36÷2]
