The solutions to the questions are

The number we are using is 5
The perfect square number closest to the area is 1024
The estimated side length is 32

<h3>What are areas?</h3>

The area of a shape is the amount of space on the shape

For most regular quadrilaterals, you multiply the side lengths to determine the area

<h3>The number to use</h3>

The area expression is given as

Area = ▢ × 102 + ▢ × 101 + 6

From the question, we can use any number

However, this number must be positive

Assume the number is 5

So, we have

Area = 5 × 102 + 5 × 101 + 6

<h3>The perfect square number closest to the result</h3>

In (a), we have:

Area = 5 × 102 + 5 × 101 + 6

Evaluate

Area = 1021

The perfect square number closest to this is

Closest = 1024

<h3>The estimated side length</h3>

In (b), we have

Closest = 1024

Rewrite as

Area = 1024

Take the square roots

Length = 32

Ronaldo can kick a soccer ball 35 meters per second which is about 80 mph. He kicked the ball from one end of the field to the o

professor190 [17]

Answer:

$t=3.142sec$

Step-by-step explanation:

From the question we are told that:

Speed of ball $V=35m/s\approx 80 mph$

Length of field $l=110m$

Generally the equation for Time taken $t$ is mathematically given by

$t=m/V$

$t=110/35$

$t=3.142sec$

$t \approx \frac{3.142}{60}$

$t \approx 0.05hrs$

Therefore it will take the ball to get from one end of the field to the other

$t=3.142sec$

Drag each expression to show whether it is equivalent to −2.6−(−5.9) -2.6 x - -5.9 x , −2.6+(−5.9) -2.6 x + -5.9 x , or neither.

vredina [299]

Answer:

$-2.6x-(-5.9x)$ is equivalent to $-2.6x+5.9x$ and $5.9x+(-2.6x)$

$-2.6x+(-5.9x)$ is equivalent to $-2.6x-5.9x$ and $-5.9x+(-2.6x)$ .

The expressions which are equivalent to neither:

$-5.9x+2.6x$ and $5.9x-(-2.6x)$

Step-by-step explanation:

Given the expressions:

1) $-2.6x-(-5.9x)$

2) $-2.6x+(-5.9x)$

To find:

The expressions equivalent to the given expressions.

or the expressions which are not equivalent to any of the given expressions.

Solution:

First of all, let us solve the brackets from the given expressions.

$-2.6x-(-5.9x)$ can be written as $-2.6x+5.9x$ (because when we multiply a negative sign with negative, it becomes positive.)

Similarly $-2.6x+(-5.9x)$ can be written as $-2.6x-5.9x$ (because when we multiply a positive sign with negative, it becomes negative.)

Therefore, the answer is:

$-2.6x-(-5.9x)$ is equivalent to $-2.6x+5.9x$ and $5.9x+(-2.6x)$

$-2.6x+(-5.9x)$ is equivalent to $-2.6x-5.9x$ and $-5.9x+(-2.6x)$ .

The expressions which are equivalent to neither:

$-5.9x+2.6x$ and $5.9x-(-2.6x)$

Approximately how many more job openings are expected for security guards than pharmacy technicians?

Illusion [34]

Answer: c. 21,000

Step-by-step explanation:

Since, by the given diagram,

The approximate number of security guard job opening = 39,000

And, the approximate number of pharmacy technicians job opening = 18,000

Hence, the difference of the number of security guard job opening and the number of pharmacy technicians job opening = 39,000 - 18,000 = 21,000

Thus, the job openings for security guards is approximately 21000 greater than that of pharmacy technicians.

⇒ Option C is correct.

Lena has 2 boxes of buttons A and B.In total are 1.200 buttons .She move 360 buttons from box A to B.There are now 3 times as ma

Fittoniya [83]

Answer:

660

Step-by-step explanation:

Let A = number of buttons in Box A

and B = number of buttons in Box B

We have two conditions:

(1) A + B = 1200

(2) B + 360 = 3(A – 360) Remove parentheses

B + 360 = 3A - 1080 Subtract 360 from each side

(3) B = 3A - 1440 Substitute (3) into (1)

A + 3A - 1440 = 1200 Combine like terms

4A - 1440 = 1200 Add 1440 to each side

4A = 2640 Divide each side by 4

A = 660
