Answer:

9 bookcases

Step-by-step explanation:

(6 1/4) divide by 2/3 convert the first one to a mixed fraction, 6*4 =24 +1 = 25/4

and then common denominator 2/3 = 8/12 and 25/4 = 75/12 and then 75 / 8 = 9.----- but you can only paint 9.

Answer:

(a+2) (a-18)

Step-by-step explanation:

Factoring a2-16a-36

The first term is, a2 its coefficient is 1 .

The middle term is, -16a its coefficient is -16 .

The last term, "the constant", is -36

Step-1 : Multiply the coefficient of the first term by the constant 1 • -36 = -36

Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -16 .

-36 + 1 = -35

-18 + 2 = -16 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 2

a2 - 18a + 2a - 36

Step-4 : Add up the first 2 terms, pulling out like factors :

a • (a-18)

Add up the last 2 terms, pulling out common factors :

2 • (a-18)

Step-5 : Add up the four terms of step 4 :

(a+2) • (a-18)

Which is the desired factorization

Answer:

m=1/2, b=1

Step-by-step explanation:

y=1/2x+1

y=mx+b

y is the y coordinate

m is the slope

x is the x coordinate

b is the y-intercept

You would identify that 1/2 is substituted into the equation as m aka the slope and 1 substituted for the b value aka y-intercept

Answer:

Washing machines usually cost between $1.25 and $1.75 per load. Prices for dryers are a whole different ball of wax. Some dryers will charge you between $1 and $2 per load, while other dryers charge you by the minute — say, $0.25 for the first 15 minutes, then an additional $0.25 for every 10 minutes after that.Jul 17, 2019

Answer:

900

Step-by-step explanation:

The equivalent degree measure of 5π ard is 900°.

We have I, II, III, IV quadrants.

In quadrant I the referece angle Ф is Ф.

In quadrant II the referece angle Ф is (π - Ф).

In quadrant III the referece angle Ф is (π + Ф).

In quadrant IV the referece angle Ф is (2π - Ф).

We know π is equal to 180°.

The conversion of radian to degrees is we multiply the radian value by 180°/π.

Given, The radian measure is 5π.

Therefore, the equivalent degree measure is,

= (5π)×(180/π).

= (5×180)°.

= 900°.

Answer:

29.5r - 33.65s

Step-by-step explanation:

Answer:

The correct answer is Option B: $39000

Step-by-step explanation:

Given that

Price of House = P = $650000

Rate of commission = r= 6%

In order to calculate the commission amount of Kathy, we only have to calculate 6% of $650000 or by simply multiplying the price by 0.06

So,

[tex]Commission = 6\%\ of\ 650000\\=0.06*650000\\=39000[/tex]

The commission is: $39000

Hence,

The correct answer is Option B: $39000

Answer:

[tex]\frac{25}{10x-1}[/tex]

Step-by-step explanation:

The multiplicative inverse of "a" is " [tex]\frac{1}{a}[/tex] "

a × [tex]\frac{1}{a}[/tex] = 1

~~~~~~~~~~~

[tex]\frac{1}{5}[/tex] ( 2x - [tex]\frac{1}{5}[/tex] ) = [tex]\frac{2}{5}[/tex] x - [tex]\frac{1}{25}[/tex]

1 ÷ ( [tex]\frac{2}{5}[/tex] x - [tex]\frac{1}{25}[/tex] ) = 1 ÷ ( [tex]\frac{10x}{25}[/tex] - [tex]\frac{1}{25}[/tex] ) = 1 ÷ ( [tex]\frac{10x - 1}{25}[/tex] ) = [tex]\frac{25}{10x-1}[/tex]

The multiplicative inverse of the product is  [tex]\frac{25}{10x-1}[/tex]

Answer:

B>18

Step-by-step explanation:

I like to rewrite it like this:

b-8>10

Now solve:

b>18

Answer: b >18

Step-by-step explanation: add 8 to both sides .( 8+10 < b - 8+8) now you get 18 < b .But variable must go first so you put b and then flip the inequality sign to > and put 18.So now you have b >18 as your inequality.

Answer:  the answer is C 52

Step-by-step explanation:

The length of the fencing needed is given by the lengths of the lines

that goes around the space she wants to fence shown in the graph.

Correct response:

The coordinates of the vertices of the fenced area are presented as

follows;

A(-7, 7), B(4, 7), C(6, -7), and D(-7, -7)

Therefore, by finding the distance between the given points, we have;

Length of AB = 4 - (-7) = 11

Length of AD = 7 - (-7) = 14

Length of CD = 6 - (-7) = 13

Length of BC = √((6 - 4)² + (-7 - 7)²) = [tex]\sqrt{200}[/tex] = 10·√2

Length of fencing needed, L = AB + AD + CD + BC

Which gives;

L = 11 + 14 + 13 + 10·√2 = 38 + 10·√2
