<u>Answer (1):</u>

Coefficient of any term  means the number multiplied in that term including sign.

ab^2 is same as 1ab^2.

Hence required coefficient is 1.



<u>Answer (2):</u>

4(3-7)^2+102


=4(-4)^2+102


=4(16)+102


=64+102


=166


Hence final answer is 166


<u>Answer (3):</u>

\sqrt{\frac{49}{25}}


=\frac{\sqrt{49}}{\sqrt{25}}


=\frac{7}{5}


Hence final answer is \frac{7}{5}

<u>Answer:</u>

1. Coefficient is 1

2. 166

3. \frac{7}{5} or 1\frac{2}{5}

<u>Step-by-step explanation:</u>

1. Since there is no number mentioned before the term ab^2 therefore its coefficient is 1. (1ab^2)


2. 4(3 – 7)^2 + 102

Using the order of operations, we will start by solving in the brackets first to get:

4(-4)^2+102

4(16)+102

64+102

166


3. \sqrt{\frac{45}{25}  }

SInce both the numerator and the denominator are under the square root so we can write them as:

\frac{\sqrt{49}} \sqrt{25}

\frac{7}{5}

\frac{7}{5} is an improper fraction so we can write it in mixed form as 1\frac{2}{5}

Blain is two years older than three times Jillians age. Jillian is also 16 years younger than Blain. How old is Blain?
Ipatiy [6.2K]

The age of Blain is 23 years old

<h3><u>Solution:</u></h3>

Let the age of Blain be "a" and age of Jillian be "b"

Given that Blain is two years older than three times Jillians age

So we can frame a equation as:

age of blain = 2 + 3(age of Jillian)

a = 2 + 3b ----- eqn 1

Also given that Jillian is also 16 years younger than Blain

Age of Jillain = Age of Blain - 16

b = a - 16 ---- eqn 2

Substitute eqn 2 in eqn 1

a = 2 + 3(a - 16)

a = 2 + 3a - 48

a - 3a = -46

-2a = -46

a = 23

Thus the age of Blain is 23 years old

For safety reasons, four different alarm systems were installed in the vault containing the safety deposit boxes at a beverly hi
AleksAgata [21]
The probability any one system works is 0.99
So the probability of any one system failing is 1-0.99 = 0.01, so basically a 1% chance of failure for any one system

Multiply out the value 0.01 with itself four times
0.01*0.01*0.01*0.01 = 0.000 000 01
I'm using spaces to make the number more readable
So the probability of all four systems failing is 0.00000001
Subtract this value from 1 to get
1 - 0.00000001 = 0.99999999

The answer is 0.99999999 which is what we'd expect. The probability of at least one of the systems working is very very close to 1 (aka 100%)

One shelf will hold 45 pounds of boxes. If you have to store 270 pounds of boxes, how many shelves will you need?
arlik [135]

Hi!

We will solve this using ratios, like this:

1 shelf holds 45 pounds

x shelves hold 270 pounds

______________________

x = (270*1)/45

x = 270/45

x = 6

6 shelves will be needed to hold 270 pounds of boxes.

Hope this helps!
