<h3>Hello There!!</h3>

<h3><u>Given</u>:-</h3>

Altitude (AB) = 9cm

Base (BC) = 12cm

Hypotenuse (AC) = ?

$\fbox \text{According To Pythagoras Theorem = }$

$\text{(Hypotenuse)² = (Altitude)² + (Base)²}$

Inserting The Values

$\text{(Hypotenuse)²} =( {9})^{2} + (12) {}^{2} \\ \\ \implies \text{(AC)} {}^{2} = 81 + 144 \\ \\ \implies \text{(AC}) {}^{2} = 225 \\ \\ \implies \text{AC} = \sqrt{225} \\ \\ \implies \text{AC} = 15$

$\therefore \text{Hypotenuse \: (AC)} = 15 \text{cm}$

Option B= <em>15cm</em> is the <u>correct answer</u>

There are 12 cans of soup in a carton. Each can has a

pickupchik [31]

Answer:

The required amount of paper is 2715.23 $cm^{2}$ .

Step-by-step explanation:

The cans of soup has a shape of a cylinder, so that;

The surface area around a cylinder = 2 $\pi$ rh

Where: r is the radius of the can, and h is its height.

From the given question, diameter = 8 cm, then;

radius = $\frac{diameter}{2}$

= $\frac{8}{2}$

r = 4 cm

Surface area around one of the cans = 2 x $\frac{22}{7}$ x 4 x 9

= 226.2857

Surface area around one of the cans = 226.28 $cm^{2}$

So that, the total amount of paper required to make labels around each of the 12 cans can be determined by:

12 x 226.2857 = 2715.4284

The required amount of paper is 2715.23 $cm^{2}$ .

A rectangular exercise mat has a perimeter of 36 feet. The length of the mat is twice the width. Write and solve an equation to

denpristay [2]

Answer:

Part a) The length of the mat is $12\ ft$

Part b) The area of the mat is $72\ ft^{2}$

Step-by-step explanation:

step 1

Find the length

Let

L-----> the length of the rectangle

W---> the width of the rectangle

we know that

The perimeter of rectangle is

$P=2(L+W)$

$P=36\ ft$

$36=2(L+W)$

$18=(L+W)$ ----> equation A

$L=2W$ -----> equation B

substitute equation B in equation A

$18=(2W+W)$

solve for W

$18=3W$

$W=18/3=6\ ft$

Find the value of L

$L=2(6)=12\ ft$

step 2

Find the area

The area of rectangle is equal to

$A=LW$

substitute the values

$A=(12)(6)=72\ ft^{2}$
