Answer:

Step-by-step explanation:

Depending on what type of fraction you're trying to simplify there are different ways.

One subtraction example would be:

6-3/7-4 you minus the numerator and denominator to get 3/3 since we have 3 on both top and bottom our simplified answer would be 1

Answer:

Divide the numerator and denominator by their greatest common divisor.

Step-by-step explanation:

Example:

38/57 = (2·19)/(3·19)

Dividing numerator and denominator by the factor 19 that is common to both, we have the simplest form:

38/57 = 2/3

___

The process is aided immensely by you having mastery of your multiplication tables through at least 12×12, and by having a good feeling for the factorization of all numbers less than 100.

Some calculators work well with fractions, so can simplify them for you. If you don't have either of the above, then you need to have a good understanding of how to find the greatest common divisor of two numbers. Euclid's algorithm is a useful tool for this.

Landon welded three pieces of metal together to form a triangle with side lengths that measure 8 inches, 9 inches and 17 inches.

Ray Of Light [21]

Answer:

<h3>No, it is not a right triangle</h3>

Step-by-step explanation:

In order to know whether the triangle is a right angle, we need to show that the square of the longest side is equal to the sum of the square of the other two sides

Longest side = 17in

other two sides = 8in and 9in

Check:

17² = 289

Sum of the square of other two sides

= 8² +9²

= 64 + 81

= 145

Since 17² ≠ 8² +9², hence the triangle that Landon created is not a right triangle

Jenn went shopping and spent $112. She bought a book for $24 and CD's that cost $8 each. What equation would you use to find out

slavikrds [6]

I would use the equation
24 + 8x = 112

let x = the amount of CDs she bought.

Hope this helps!!

To assess the accuracy of a laboratory scale, a standard weight that is known to weigh 1 gram is repeatedly weighed 4 times. The

zhannawk [14.2K]

Answer:

(0.9464,1.034)

Step-by-step explanation:

First find the mean μ of all values as;

(0.95+1.02+ 1.01+ 0.98 ) /4 =0.99

μ=0.99

Find the standard deviation as;

-For each value subtract the mean and square the results

0.95-0.99 = -0.04 , -0.04² = 0.0016

1.02-0.99= 0.03, 0.03²=0.0009

1.01-0.99= 0.02, 0.02²= 0.0004

0.98-0.99 = -0.01, -0.01²=0.0001

Find mean of squared deviations as;

(0.0016+0.0009+0.0004+0.0001)/4 =0.00075 ----variance

Standard deviation = √0.00075 = 0.0274

δ = 0.0274

n=4

Thus n< 30 , confidence interval for μ = x ± t*δ/√n ---------(i)

Degree of freedom (df) = n-1 =4-1 =3

The t value for 95% confidence with df= 3 is t=3.182

Substituting the values in equation (i)

0.99 ± 3.182 * 0.0274/√4

0.99 ± 3.182 * 0.0274/2

0.99 ± 3.182 * 0.0137

0.99 ± 0.0436

(0.9464,1.034)

A baseball coach bought some bats and gloves for the school's baseball team.the bats cost $20 to $35,and gloves cost $30 to $60.

arlik [135]

Max cost of 15 bats = 15 x 35 = $535

Min cost of 15 bats = 15 x 20 = $300

Max cost of 12 gloves = 12 x 60 = $720

Mix cost of 12 gloves = 12 x 30 = $360

Min total cost = 360 + 300 = $660

Max total cost = 535 + 720 = $1255

The range is from $660 to $1255

=============> Answer (A) is out of the range
