Answer:

$34\times 65+34\times 27$

Step-by-step explanation:

We have been given an expression $34\times (65+27)$ . We are asked to expand our given expression.

We will use distributive property $a(b+c)=ab+ac$ to expand our given expression.

Using distributive property, we will distribute 34 to 65 and 27 as:

$34\times 65+34\times 27$

Therefore, the expanded form of our given expression would be $34\times 65+34\times 27$ .

36 x (65+27) is the same as 36(65+27) .. you are able to distribute the 36 ( distributive property) onto the 65 and 27 and add them. Also, you can add the numbers in between the parenthesis and multipy them by 36. Nonetheless, you would arrive at the same answers.

Ruden bought 6 new books for his collection, increasing his collection by 12%. How many books did he have before his purchase?

forsale [732]

Answer:

he had 44 books before he bought those 6

Step-by-step explanation:

If you multiply 6 times 2 it is 12, which means if you take away 12 from 100 that is 88. if you divided 88 by 2 (the same thing you did to the 6 to make it 12%) that would be 44.

What is the equation of a line perpendicular to:

Nataly [62]

Step-by-step explanation:

"perpendicular" means it creates a right angle (90°) with the original line.

a key element is the slope (the incline) of the line.

it is the factor of x (here 1/4 for the original line) and is defined as the ratio of "y coordinate change / x coordinate change" when going from one point on the line to another.

the given slope of 1/4 means that for every increase in x by 4 units y increases by 1 unit.

now if you want to draw a few random lines, and then draw lines that cross them with a right angle, you will see very quickly the relationship of the slopes of the crossing lines :

for the slope of the perpendicular line x and y of the original slope trade places (the ratio turns "upside-down") and the sign of the slope flips (if the original line goes up, then the perpendicular line goes down and vice versa. so + turns into -, and - into +).

so, our original slope 1/4 turns into -4/1 = -4.

we still have infinite possibilities to draw such a perpendicular line (more up or more down on the coordinate grid).

to finally "nail" one particular line we need to use the given point and solve for the y-intercept.

the general slope-intercept form is

y = ax + b

a is the slope, b is the y-intercept (the y value for x = 0).

so, using the slope (-4) and the point (2, 5) we have

5 = -4×2 + b = -8 + b

13 = b

so, the full equation is

y = -4x + 13

The Powerball lottery is decided every Wednesday and Saturday night by drawing five white balls out of a drum with 69 balls and

Doss [256]

Answer: a) 11,238,513 and b) 292,201,338

Step-by-step explanation:

Since we have given that

Number of white balls = 69

Number of white balls drawn = 5

Number of red balls = 26

Number of red balls drawn = 1

According to question, The Powerball jackpot is won by matching all five white balls in any order and the red Powerball.

So, a) Possible different ways of Powerball tickets can be purchased is given by

$^{69}C_5\\\\=11,238,513$

And

b) Number of possible ways of different winning Poweball tickets are there would be

$26\times ^[69}C_5\\\\=292,201,338$

Hence, a) 11,238,513 and b) 292,201,338
