Katy and Jane construct a four-sided wall to surround their castle. The wall has a perimeter of

PilotLPTM [1.2K]

Answer:

The correct length is 34 feet.

Step-by-step explanation:

Let us assume that the wall created is a rectangle ABCD as shown in the attached image.

We know that opposite sides of a rectangle are equal.

Perimeter of a closed figure is calculated by adding all the sides of the figure.

Here, from the figure, the perimeter is : AB + BC + CD + DA

AB and CD are equal to length.

BC and DA are equal to width.

So,

$Perimeter = 2 \times (length + width) ....... (1)$

Here, we are given that perimeter is 100 feet and width = 16 feet

Putting values in equation (1):

$100 = 2 \times (16 + length)\\\Rightarrow 50 = 16 + length \\\Rightarrow length = 34 feet$

Hence, length is 34 feet.

Choose the fraction that has not been reduced to simplest form 19/3810/1921/3415/18

lozanna [386]

19/38 and 15/18

Explanation:

19/38 can be reduced as there is a factor other than 1 that can divide without a remainder. Factor is 19

It can still be reduced because 19*2 = 38

19/38 = 1/2

10/19 cannot be reduced as there is no factor other than one to divide without a remainder

21/34 cannot be reduced as there is no factor other than one to divide without a remainder

15/18 can be reduced as there is a factor other than 1 that can divide without a remainder.

The factor is 3

15/18 = 5/6

Fraction that has not been reduced to simplest form are 19/38 and 15/18

A=63°

bekas [8.4K]

Answer:

B. 7.35 inches

Step-by-step explanation:

In the triangle:

A=63°
c = 7.75 inch
B = 47°

Now we know that:

$\angle A+\angle B+\angle C=180^\circ$ (Sum of angles in a \triangle)\\63^\circ+47^\circ+\angle C=180^\circ\\\angle C=180^\circ-(63^\circ+47^\circ)\\\angle C=70^\circ$

Using the Law of Sines

$\dfrac{a}{\sin A} =\dfrac{c}{\sin C}\\\\\dfrac{a}{\sin 63^\circ} =\dfrac{7.75}{\sin 70^\circ} \\\\a=\dfrac{7.75}{\sin 70^\circ} \times \sin 63^\circ\\\\a=7.35$ inches (to the nearest hundredth of an inch)$
