The first step to solve this problem is to find the area of the rectangular piece of fabric.

A of triangle = bh/2

A = (14 cm) (6 cm) /2

A = 84 cm^2 / 2

A = 42 cm

And since there are 31 pieces of the fabric, the total area of all the pieces of fabric is:

31 pieces of fabric x 42 square centimeters per piece = 1,302 square centimeters

To computer how many congruent triangular patches can be cut, you have to divide the total area of the fabric pieces with the area of the congruent triangle:

1,302 square centimeters / 21 square centimeters = 62

Therefore, Leia can cut 62 patches.

While visiting Crimson Lake, Sally decided to go Kayaking. The rangers charge $8.50 per hour in addition to a $25.00 deposit to
salantis [7]

The total cost to rent the Kayak will be $50.50

Step-by-step explanation:

Let h be the number of hours

Given

Charges per hour = $8.50

Renting Charges = $25.00

The renting charges are constant and will be used only once while the per hour charges will be calculated as number of hours change.

The function will be written as:

f(h) = 8.50h +25.00

Here h is the number of hours.

From 11:30 AM to 02:30 PM makes three hours. So, to find the cost for 3 hours we have to put h = 3

f(h) = 8.5(3) + 25.00\\= 25.5+25.00\\= 50.5

Hence,

The total cost to rent the Kayak will be $50.50

Help please! will give brainliest! and can please explain.
storchak [24]

Answer: 150

We know that cos Ф = sin (90 - Ф)

If Ф = 150, then:

cos 150 = sin (150 - 90)

cos 150 = sin 60

Using the equation they gave us:

cos 150 = sin ( \frac{150}{3} - 10)

cos 150 = sin 60

Complete the equation to show how many thirds are equivalent to<br> 8/12 = ?/3
anygoal [31]

Answer:

\frac{2}{3}

Explanation:

What we need to do is to convert \frac{8}{12} into a new - but still equal - fraction, one with a denominator of 3. In order to convert a fraction, you either divide or multiply both the denominator and the numerator by the same number.

We know that the answer has to be a fraction with the denominator of 3. Take a look at the denominator of \frac{8}{12} - it's 12. Ask yourself: 12 divided by what number equals 3? That number would 4.

So, divide 8 by 4 as well and you would get 2. Therefore, the numerator would be 2 and the answer is \frac{2}{3}.
