5 5/6 divided by 2 1/3

Answers

Answer:

2[tex]\frac{1}{2}[/tex] or 2.5

Step-by-step explanation:

5 5/6 = 35/6

2 1/3 = 7/3 = 14/6

multiply by the reciprocal of 14/6

35/6 * 6/14 = 210/84 = 5/2

Answer:

2.5

Step-by-step explanation:

[tex]5\frac{5}{6}[/tex] ÷ [tex]2\frac{1}{3}[/tex]

First, convert both fractions into the form of an improper fraction. This can be done by multiply the "number" outside of the fraction by the denominator of the fraction, that is the number underneath the fraction bar. Then, add the result to the numerator, the number over the fraction bar.

[tex]\frac{35}{6}[/tex] ÷ [tex]\frac{7}{3}[/tex]

Now, one must reciprocate the second fraction, in other words, switch the places of the denominator and the numerator on the second fraction, then change the division sign to a multiplication sign. Remember, dividing two fractions is the same as multiplying by their reciprocal.

[tex]\frac{35}{6} * \frac{3}{7}[/tex]

Now multiply the two fractions, multiply the numerator by the numerator, and the denominator by the denominator, then simplify.

[tex]\frac{105}{42}\\\\= 2.5[/tex]

A.45 cm2

B.40 cm2

C.36 cm2

D.32 cm2

Answers

Answer:

40 cm2

Step-by-step explanation:

b. 40 cm² approximately.

What is Rectangle?

A rectangle is a two-dimensional closed geometry with four sides, four corners, and four 90° right angles. The opposite sides of a rectangle are equal and parallel. The area of a rectangle is the multiplication of length and width.

Given the length of the rectangle is 8.18 cm and its width is 4.83 cm. From that

area = length * width

area = 8.18* 4.83

area = 39.5094 cm²

Therefore, the closest estimate of the area of the rectangle MNPQ is 40 cm².

Gerard concluded that the triangle with sides StartRoot 95 EndRoot feet, 8 feet, and StartRoot 150 EndRoot cannot be used as a building frame support on the house because it is not a right triangle. How did Gerard come to that conclusion? Explain.

ANSWER: Gerard came to that conclusion because 95 + 8 equals 159. In order for the triangle to be a right triangle the sum of the two shorter lengths must equal the length of the hypotenuse. 150 does not equal 159.

Answer:  so it is 150
