Answer:

Esmerelda did not use the reciprocal of the divisor.

Step-by-step explanation:

A complex fraction is another way to show division of two fractions.  In this case, we are dividing -5 1/4 by 3/2.

We first convert -5 1/4 to an improper fraction.  To do this, multiply the whole number by the denominator; this gives us -5(4) = -20.  Then add the -1 (negative since the fraction is negative); this gives us -21/4.

This means we are dividing -21/4 by 3/2.

To divide fractions, we multiply by the reciprocal; this means we flip the second fraction and multiply.  We would then multiply -21/4 by 2/3.  This is the step Esmerelda did not do.

A circle is cut from a square piece of cloth, as shown: How many square inches of cloth are cut from the square? (π = 3.14)
Vinil7 [7]

Answer:

2122.64 in^2

Step-by-step explanation:

Use the formula for the area of a circle: A=πr^2

The radius will be half the width of the cloth so 52÷2=26

26^2=676

Multiply by π given as 3.14

676×3.14=2122.64 square inches.

The symbol (carat) ^ is used to indicate an exponent when the keyboard doesn't have superscript.

An Eurasian lynx travled 46 miles. It took the
Eddi Din [679]

Answer:

A Eurasian lynx covered 1.07 miles per day.

Step-by-step explanation:

The distance traveled by a Eurasian lynx = 46 miles

The days to cover the 46 miles distance = 43 days

Divide the total distance miles by the total number of days to determine the miles per day.

Thus,

Miles per day = Tota distance / Totdal days

                       = 46 / 43

                       = 1.07 miles per day

Thus, An Eurasian lynx covered 1.07 miles per day.

Will mark brainliest! Would also really appreciate it if someone could explain it as well!
guapka [62]

Answer:

sin (x) ≥ 0, between 0° and 180° or 0 and π,

sin(x) ≥ 1/2, between 30° and 150° or π/6 and 5π/6

Step-by-step explanation:

This is how I would do it. Subtract sin(x) from both sides

2sin^{2} (x) - sin(x) ≥ 0 , then factor out sin(x)

sin(x) [2 sin(x) - 1] ≥0, then set each factor ≥ 0

sin(x) ≥ 0 and 2 sin(x) - 1 ≥ 0

sin (x) ≥ 0, between 0° and 180° or 0 and π

2 sin(x) ≥ 1

sin(x) ≥ 1/2, between 30° and 150° or π/6 and 5π/6
