Danny bought 8 rolls of paper towels. He has 204.8 meters of paper towels in all. How many meters of paper towels are on each roll? A) 21.52 B) 25.12 C) 25.60 D) 26.52​

Answer:

3 - 3 = 0 units There is no distance, the points are in the same place.

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

15x2 = 30

30+25 = 55

Answer:

Step-by-step explanation:

Note all operations:

Create an equation, and make the unknown number be x. 25 is added to x multiplied by 2, which, in all, equals 55:

[tex]2x+25=55[/tex]

Now solve for x. Subtract 25 from both sides:

[tex]2x+25-25=55-25\\\\2x=30[/tex]

Divide both sides by 2:

[tex]\frac{2x}{2}=\frac{30}{2} \\\\x=15[/tex]

The number is equal to 15.

:Done

CHECK:

Insert the value of x to see if it is true:

[tex]2(15)+25=55\\\\30+25=55\\\\55=55[/tex]

This is true, so the value of x is also true.

Answer:

y = - 4x + 38

Step-by-step explanation:

A(3, 9)

B(5, 1)

[tex]m_{AB}[/tex] = [tex]\frac{1-9}{5-3}[/tex] = - 4

CD║AB

C(9, 2)

y - 2 = - 4(x - 9)

y = - 4x + 38

Answer:

A) [tex]f^{-1}(n)= (n+2)^3[/tex]

Step-by-step explanation:

[tex]f(n) = \sqrt[3]{n} -2[/tex]

[tex]y = \sqrt[3]{n} -2[/tex]

[tex]y = n^{1/3}-2[/tex]

[tex]n = y^{1/3} -2[/tex]

[tex]n + 2 = y^{1/3}[/tex]

[tex]y = (n + 2) ^3[/tex]

[tex]f^{-1}(n) = (n + 2)^3[/tex]

Hope this helps!

Answer:

Option A

Step-by-step explanation:

f(n) =∛n-2

y= ∛n-2

Interchange y and n

n =∛y-2

Subtract -2 on both sides

n+2 = ∛y

both  both sides  to the 3rd power:

(n+2) to the 3rd power = y

Inverse :

f-1(n) =     (n+2) to the 3rd power  (option A)

5 is your answer because if you plot these on a graph you would know how many points there are in between them and there are 5

Answer:

1,035,600

Step-by-step explanation:

since the rate sales increased 2.5% per year 8*2.5=20/100=0.2*863,000=172,600 and since we already are earning 863,000 so 863,000+172,600=1,035,600

its good to know if a number is positive or negative because something as simple as forgetting the signs such as - + could drastically change your answer

Answer:

-19.38

Step-by-step explanation:

E(x)=4,980*1/25000+1,980*2/25,000+980*3/25,000+480*5/25,000+80*10/25,000-20*24,979/25,000

E(x)=0.1992+0.1584+0.1176+0.096+0.032-19.9832

E(x)= -19.38

Answer:

x=2

Step-by-step explanation:

In order to solve the inequality, first simplify it. -8 (5x -7) can be simplified be distributing. Multiply -8 to each term.

-24 = -40x + 56  now you can solve it start by subtracting 56 on both sides

-80 = -40x now divide -40 on both sides

2=x

I hope this helps :)

have a nice day

wow how in the heck did you do that 0-o your rich dude pls explain how u did it T-T

Answer:

the answer would be 27.6.

Step-by-step explanation:

sorry for the horrible handwriting, hopefully u can understand this!!

log₃(-2 tan(x)) = 1/2

Write both sides as powers of 3, and use the property [tex]b^{\log_ba}=a[/tex]:

[tex]3^{\log_3(-2\tan x)}=3^{\frac12}[/tex]

-2 tan(x) = √3

Then solve for x :

tan(x) = -√3 / 2

x = arctan(-√3 / 2) + nπ

x = -arctan(√3 / 2) + nπ

where n is any integer.

Kindly check explanation

Step-by-step explanation:

Given that:

Percentage of insured home owners = 40% p = 0.4

Selecting 4 home owners (x) ;

x = 0, 1, 2, 3, 4

Using bernoulli;

nCx * p^x * (1 - p)^(n-x)

For X = 0

4C0 * 0.4^0 * 0.6^(4-0) = 0.1296

X = 1

4C1 * 0.4^1 * 0.6^(4-1) = 0.3456

X = 2

4C2 * 0.4^2 * 0.6^(4-2) = 0.3456

X = 3

4C3 * 0.4^3 * 0.6^(4-3) = 0.1536

X = 4

4C4 * 0.4^4 * 0.6^(4-4) = 0.0256

B.) The most likely value for X are 1 and 2 with probabilities of 0.3456 respectively.

C.) probability that atleast 2 of the 4 selected have earthquake insurance ;

P(X ≥ 2) = p(2) + p(3) + p(4)

P(X ≥ 2) = 0.3456 + 0.1536 + 0.0256

P(X ≥ 2) = 0.5248

Think of the order of operations or PEMDAS: Parentheses, exponents and roots, multiplication, addition, and subtraction. When solving an equation you use the order of PEMDAS.

Answer:

option A) is correct.

Step-by-step explanation:

As we know that when we reflect across the line [tex]y=-x[/tex], the x-coordinate and y-coordinate would change places and be negated.

So the formula about the reflection across [tex]y=-x[/tex] will be:

(x, y) ⇒ (-y, -x)

From the graph, the vertices of the triangle are:

As the rule of reflection across [tex]y=-x[/tex] will produce the image with the vertices T', U' and V' which are as follows:

(x, y) ⇒ (-y, -x)

So, the vertices of U', T' and V' will be:

Therefore, option A) is correct.

Answer:

X = 8, y = 8

Step-by-step explanation:

This question is an optimization problem. Two equations are going to be needed here

n = x+y

P = xy

Such that 64 = xy

When we divide through by x we get:

y = 64/x

So that n becomes:

n = x + 64/x

n = x+64x^-1

We take derivative

n' = 1-64x^-2

When n' = 0 then a min|max occurs

0 = 1-64x^-2

Such that:

64/x² = 1

Divide through by x²

64 = x²

x = √64

x = 8

Remember y = 64/x

So,

Y = 64/8

Y = 8.

X = 8, y = 8

Thank you!

Answer:

Domain: All real numbers greater than or equal to 1.

Step-by-step explanation:

Answer 1: -14 is not in the domain

Answer 2: 4 is included in the domain

Here is the set up:

Side 1 is 4x.

Side 2 is 5x + 3

Side 3 is 5x + 1

The perimeter is 102.

Perimeter = side 1 + side 2 + side 3

102 = 4x + 5x + 3 + 5x + 1

102 = 14x + 4

Take it from here.

Answer:

b = 2

Step-by-step explanation:

Since the two lines are parallel, their slope is the same.

Slope = -1

The function: y = -x + b

Plug in the coordinate values to solve for b.

-6 = -8 + b

-6 + 8 = b

2 = b

b = 2
