Answer:

a. $160

b. $894

Step-by-step explanation:

according the the info we have, each square is 1/4 of an inch. so 4 squares would equal one inch (1/4 x 4 = 1). and one inch is a scale of 16 feet. to find the length of one square:

1 inch = 4 squares

4 squares = 16 feet

1 square = 1/4 of an inch

1/4 of an inch = 1/4 of 4 squares

1 square = 1/4 of 16 feet    {1 square = 1/4 of an inch and 4 squares = 16 feet}

1 square = 4 square feet

a. count the number of squares: 8

now find the number of square feet 8 squares are using the conversion:

8 x 4 = 32

the bathroom is 32 square feet

one square foot of tile costs $5

now find the cost of 32 square feet:

$5 x 32 = $160

b. the square feet of the bathroom in 32 sqft

now do the same thing before for the living room:

28 square, so the living room is 112 (because 1 square = 4 square feet)

the find the cost of carpet per square foot, divide the cost per yard by 3 (1 yard = 3 feet)

18/3 = 6

so one square foot of carpet costs $6

now find the cost to carpet the bathroom and living room:

$6 x 32 = $192

$6 x 112 = $672

the total cost is

$672 + $192 = $894

the total cost to carpet the bathroom and living room is $894

p.s. who carpets their bathroom? lol

We want to see which expression does not belong, the one that has a difference with the others is the third one, so that is the one that does not belong.

Here you need to remember the rules:

[tex]a^x*a^y = a^{x + y}\\\\(a^x)^y = a^{x*y}\\\\\frac{a^x}{a^y} = a^{x - y}[/tex]

Now we can use these to rewrite the given expressions as:

[tex]\frac{2^8}{2^5} = 2^{8 - 5} = 2^3 = 8[/tex]

[tex](\frac{3}{4} )^{-5}*(\frac{3}{4})^8 = (\frac{3}{4})^{-5 + 8}= (\frac{3}{4} )^3[/tex]

[tex](4^{-5})^8 = 4^{-5*8} = 4^{-40}[/tex]

[tex]\frac{10^8}{5^5} = \frac{2^8*5^8}{5^5} = (2^8)*(5^{8-5}) = 2^8*5^3[/tex]

So you can see that in the first, second, and fourth expressions we have positive exponents and there always appears the exponent 3, while on the third one that does not happen, so the one that does not belong is the third expression.

Step-by-step explanation:

Answer:

sin(0) = opposite/hypotenuse = (3√3)/√31

cos(0) = adjacent/hypotenuse = 2/√31

tan(0) = opposite/adjacent = (3√3)/2

cot(0) = 2/(3√3)

sec(0) = 1/cos(0) = 1/(2/√31) = √31/2

Step-by-step explanation:

Hypertenuse = √[2^2 + (3√3)^2] = √[4 + 27] = √31

sin(0) = opposite/hypotenuse = (3√3)/√31

cos(0) = adjacent/hypotenuse = 2/√31

tan(0) = opposite/adjacent = (3√3)/2

cot(0) = 2/(3√3)

sec(0) = 1/cos(0) = 1/(2/√31) = √31/2

Answer: Choice A

Point A is plotted 4 units to the right and 3 units above the origin. Point B is plotted 2 units to the right of and 1 unit above the origin. Point C is plotted 3 units to the right and 4 units above the origin

====================================================

Explanation:

The point A(4,3) means we start at the origin and move 4 units to the right and 3 units up. The x and y axis are separate number lines to mark a location

B(2,1) means we move 2 units to the right and 1 unit up

C(3,4) means we move 3 units to the right and 4 units up

Each time we plot a new point, we always start at the origin.

Answer:(4, 3)

Step-by-step explanation: A. A coordinate plane has an x-axis from 0 to 7 in increments of 1 and a y-axis from 0 to 7 in increments of 1. Point A is plotted 4 units to the right and 3 units above the origin. Point B is plotted 2 units to the right of and 1 unit above the origin. Point C is plotted 3 units to the right and 4 units above the origin.

Answer:

-14x + 21

Step-by-step explanation:

Use the distributive property to solve. Multiply -7 by each number in parentheses. -7 times 2x is -14 x and -7 time -3 is 21 (a negative times a negative is a positive). You should get -14x + 21 as an answer. You are no longer able to simplify any farther from there.

Answer:

Adrian is 13ft. Sofi is 9.33ft.

Step-by-step explanation:

There are two right triangles here. We use Pythagorean theorem. 12^2 plus 5^2=c^2. 144 plus 25= 169. Square root of 169 is 13. He is 13ft from the top which is the hypotenuse. She is 8^2 plus 5^2=c^2. This is 64 plus 25. C= the √89. This is 9.33ft.

Answer:

b = -4

According to the discrete distribution given, the salesman is expected to send 3.65 texts each day.

The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.

Considering the discrete distribution given in the model, we have that:

E(X) = 0.05(0) + 0.05(1) + 0.1(2) + 0.1(3) + 0.4(4) + 0.3(5) = 3.65

Answer:

C. y = -5x + 4

Step-by-step explanation:

segment with endpoints (–5, 3) and (5, 5)

Slope m = (y2-y1)/(x2-x1)

m = (5 - 3)/(5 - -5) = 2/10 = 1/5

Perpendicular lines have slopes that are negative reciprocals of one another. So slope of bisector is -5

Bisector intersects the segment at midpoints so

x = (Xa + Xb)/2 = (-5 + 5)/2 = 0/2 = 0

y = (Ya + Yb)/2 = (3 + 5)/2 = 8/2 = 4

so midpoint is (0,4)

using slope = -5

y = mx + b

4 = -5(0) + b

b = 4

then y = -5x + 4

Step-by-step explanation:

we have to simplify it as much a possible.

that means we divide top and bottom by the same whole number, until we cannot find any other number except for 1, where there is no remainder for these divisions.

so, usually if we don't see the solution right away, we go along the prime numbers starting with 2 :

can we divide 48 and 54 by 2 without remainder ?

yes, and the result is then

24/27

can we divide 24 and 27 by 2 without remainder ?

no. going to the next prime number : 3

can we divide 24 and 27 by 3 without remainder ?

yes, and the result is

8/9

can we divide 8 and 9 by 3 without remainder ?

no. and there is no other prime number I can divide both numbers with.

so, 8/9 is the lowest or simplest form.

or, z + 106° = 180° ( being straight angle )

or, z = 180°- 106°

•°• z = 74°

Now,

or, z + y = 180° ( being co-interior angle )

or, 74° + y = 180°

or, y = 180° - 74°

•°• y = 106°

~nightmare 5474~

The value of x is 74.

The value of y is 106.

The sum of angles on a straight line is 180. In order to determine the value of x, subtract 106 from 180.

x = 180 - 106 = 74

In order to determine the value of y, subtract 180 from 74

180 - 74 = 106.

for the first dealer, it would take 7.5 months and the second one would be 12 months so basically a whole year

The inequality that describes the problem is x - 30 ≤ 15

Let x represent how much money Michael expects to spend on sports wear

If Michael just started middle school this year, and his grandmother will give him some money to buy new spirit wear and buys hoodie for $30, the balance remaining will be x - 30

If Michael figures he'll need at most $15 more to buy a T-shirt, hence the resulting inequality will be:

x - 30 ≤ 15

Add 30 to both sides

x - 30 + 30  ≤ 15 + 30

x  ≤ 45

Hence the inequality that describes the problem is x - 30 ≤ 15 and Michael expects to spend at most $45 on sports wear.

Answer:

d = 363/8

Step-by-step explanation:

Let's write this as a fraction:

   8 1/4          2

------------- = -------

      d            11

One way in which this could be approached would be to interchange 'd' and '2:'

   8 1/4          d                   33             d

------------- = -------      or    -------- =  ---------

      2            11                   4(2)          11

Multiplying both sides by 11 isolates d:

33(11)                     363

-------- = d, or d = ----------
