Shannon is making three different sizes of blankets from the same material. The first measures 2.5 feet by 2 feet. She wants to
Arada [10]

Answer:

<h2>The dimensions of the third blanket are 7.5 feet by 6 feet.</h2><h2>All the blankets are similar.</h2>

Step-by-step explanation:

The size of the first blanket is 2.5 feet by 2 feet.

Shannon  wants to enlarge the first blanket by scale factor 2 to make the second blanket.

Hence, the size of the second blanket will be (2.5\times2) = 5 feet by 2\times2 = 4 feet.

Again she enlarged the second blanket by a scale factor 1.5 to make the third blanket.

Hence, the size of the second blanket will be 5\times1.5 = 7.5 feet by 4\times1.5 = 6 feet.

Enlargement only changes the size of the blanket, it does not change the shape of the blanket. Hence, all the blankets will be similar.

The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. Find the number.
Monica [59]

Equation to find number: \frac{1}{n} - 3 = \frac{20}{n}

Number's value: n = -\frac{19}{3}



Step-by-step explanation:

Let n be the unknown number.

The reciprocal basically makes the number (n in this case) a fraction. So, that being said, the reciprocal of n would be \frac{1}{n}.

The difference of three and the reciprocal of a number (\frac{1}{n}) would be \frac{1}{n} - 3.

The quotient of 20 and the number (n) would be \frac{20}{n}.

So, with this information we've gathered so far, we can come up with an equation to find what the number equals.

Equation: \frac{1}{n} - 3 = \frac{20}{n}

To find what the number equals we must solve the equation.
