4. A drawing of the top of a desk iS shown.

KATRIN_1 [288]

The area of the top of a desk which is shown and the dimensions of the top is 5 feet and 2 feet, is 10 squared feet.

<h3>What is the area of a rectangle?</h3>

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

$A=a\times b$

Here, (a)is the length of rectangle and (b) is the width of the rectangle

A drawing of the top of a desk is shown.

5 feet
2 feet

The image of drawing ins not given in the problem. Here, the length of the desk is 5 feet and the width of the desk is 2 feet according to the data.

$a=5\rm\; feet\\b=2\rm\; feet$

Put the values in the above written formula as,

$A=5\times 2A=10\rm\; ft^2$

Thus, the area of the top of a desk which is shown and the dimensions of the top is 5 feet and 2 feet, is 10 squared feet.

Write out the steps in solving 3/4 x 2 2/5

max2010maxim [7]

3/4 × 2 2/5

Turn 2 2/5 into an improper fraction.

2 2/5 = (5 × 2) + 2 = 12

So, 2 2/5 = 12/5

So, our new question is : 3/4 × 12/5

Multiply the numerators (top numbers) with one another.

Numerators : (3 × 12) = 36

Multiply the denominators (bottom numbers) with one another.

Denominators : (4 × 5) = 20

So, our answer is 36/20

However, we need this to be a mixed number.

So, how many times does 20 go into 36? Once!

So, Multiply 20 with 1, and then subtract that number from 36! :)

20 × 1 = 20

36 - 20 = 16

So, our answer is :

1 16/20

Then, you simplify it once more.

Divide the numerator and denominator by 4.

16 ÷ 4 = 4

20 ÷ 4 = 5

So, our final answer is 1 4/5

Answer:

Step-by-step explanation:

Find the common ratio r of the geometric sequence then multiply a term by r to obtain the next term

r = $\frac{a_{2} }{a_{1} }$ = $\frac{6}{-36}$ = - $\frac{1}{6}$
