Convert to percent by multiplying by 100

18%

Answer:

6ft

Step-by-step explanation:

Lets x = the width of the path the surrounding path will add 2x to the pool dimension,therefore over all dimesion: (2x+40) by (2x+60) the overall perimeter (2x + 40) + 2(2x+60) = 248 Simplify divide by 2, result (2x+40) +(2x+60) = 124

Combine like terms 2x + 2x +40 +60 =124

4x + 100 = 124

4x=124 = 100

4x=24

x=24/4

x= 6ft is the width of the path

check this by finding the perimeter with these values; 2x = 12 ft

2 ( 12 + 40 ) + 2( 12 +60 )

2( 52 + 2(72)

104 + 144 = 248; confirms our solution of x= 6 ft

Answer:

[tex]y = 2000(1.05)^{36[/tex]

Step-by-step explanation:

Given

[tex]a = 2000[/tex] -- Initial population

[tex]r = 5\%[/tex] --- Rate (monthly)

Required

Determine the population in 3 years

The question shows an exponential distribution and the final population will be calculated using:

[tex]y = a(1 + r)^x[/tex]

Where x is the number of months.

[tex]x = 3\ years[/tex]

[tex]x = 3* 12\ months[/tex]

[tex]x = 36[/tex]

So, we have:

[tex]y = 2000(1 + 5\%)^{36[/tex]

Convert % to decimal

[tex]y = 2000(1 + 0.05)^{36[/tex]

[tex]y = 2000(1.05)^{36[/tex]

B. the absolute value of -15

Step-by-step explanation:

Ok so,

lets rewrite them for it to make sense

| 12 |  = 12

| - 15 | = 15

so now the question is "which is larger 12 or 15?" and the answer is 15 obvs lol

" | " = means absolute value

Answer:

0.3333 = 33.33% of this group likes chocolate

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

Of the friends who like sprinkles, what proportion of this group likes chocolate:

So,

Event A: Likes sprinkles

Event B: Likes chocolate

15% of your friends like sprinkles (S) topping.

This means that [tex]P(A) = 0.15[/tex]

5% of your friends like Chocolate (C) and also like sprinkles (S).

This means that [tex]P(A \cap B) = 0.05[/tex]

So

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.05}{0.15} = 0.3333[/tex]

0.3333 = 33.33% of this group likes chocolate

Answer:

y = -5/3x - 5

Step-by-step explanation:

convert -3x + 5y = -1 to slope-intercept form:

5y = 3x - 1

y = 3/5x - 1/5

slope of a line perpendicular to the above equation would be -5/3

y = mx + b

-5 = -5/3(0) + b

b = -5

y = -5/3x - 5

Answer:

Part A:  No Solution

Part B:  Distributive Property

Step-by-step explanation:

4x + 2x - 6 = 6x - 11

6x - 6 = 6x - 11

-6 ≠ -11

No Solution

Answer:

Part A. Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Part B. Distributive Property

Step-by-step explanation:

Simplifying

4x + 2(x + -3) = 4x + 2x + -11

Reorder the terms:

4x + 2(-3 + x) = 4x + 2x + -11

4x + (-3 * 2 + x * 2) = 4x + 2x + -11

4x + (-6 + 2x) = 4x + 2x + -11

Reorder the terms:

-6 + 4x + 2x = 4x + 2x + -11

Combine like terms: 4x + 2x = 6x

-6 + 6x = 4x + 2x + -11

Reorder the terms:

-6 + 6x = -11 + 4x + 2x

Combine like terms: 4x + 2x = 6x

-6 + 6x = -11 + 6x

Add '-6x' to each side of the equation.

-6 + 6x + -6x = -11 + 6x + -6x

Combine like terms: 6x + -6x = 0

-6 + 0 = -11 + 6x + -6x

-6 = -11 + 6x + -6x

Combine like terms: 6x + -6x = 0

-6 = -11 + 0

-6 = -11

Solving

-6 = -11

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Answer:

-9

Step-by-step explanation:

Khan Academy huh? Well, the answer's -9.

-7 = -9 + 2

Hope that helps!

Answer:

100 cm

Step-by-step explanation:

let x be the height of Beth

and y be the height of Beth's Brother

By 1st Condition

y = 140% * x

y = (140/100) * x

y = 1.4 x ..........................(Eq 1)

By 2nd Condition

y = 140

Put the value of y in the equation 1

140 = 1.4 *x

x = 140 / 1.4

x = 100 cm

Answer:

6w + 2a = 28

Step-by-step explanation:

the expression given, 6w + 2a, contains no variable h, so it's best to just ignore that h = 5.

first, plug in the values for w and a. you can do this in whatever order you want, but i'll start with w for this example.

plug in 4 for w.

6w + 2a

6(4) + 2a

now plug in 2 for a.

6(4) + 2a

6(4) + 2(2)

after plugging in the values, your expression is 6(4) + 2(2).

all that's left is to simplify. again, this can be done in whatever order you prefer, but i'm going to start with 6(4).

6(4) + 2(2)

24 + 2(2)

continue simplifying by multiplying 2(2).

24 + 2(2)

24 + 4

now add 24 + 4.

24 + 4 = 28

so, when w = 4 and a = 2, 6w + 2a = 28.

you can check the answer by plugging those values for a and w back into the completed equation.

6w + 2a = 28

6(4) + 2(2) = 28

24 + 4 = 28

28 = 28

since both sides of the equation are equal, that means that your answer of 28 is correct! :)

Answer:

A) is correct

Step-by-step explanation:

Answer:

d/ ( a+b) = x

Step-by-step explanation:

d=ax+bx

Factor out x

d = x( a+b)

Divide each side by (a+b)

d/ ( a+b) = x (a+b)/ (a+b)

d/ ( a+b) = x

The area of the circle {1} is 9 times greater than circle {2}.

Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -

V = ∫∫F(x, y) dx dy

Given is to find how many times greater is the area of circle 1 than the area of circle 2 if circle ones radius is 9 and circle twos radius is 3.

We can write the areas of both the circles as -

A{Ο} = πR²

A{Ο1} = π x 9 x 9

A{Ο2} = π x 3 x 3

We can write -

A{Ο1} / A{Ο2} = {π x 9 x 9} / {π x 3 x 3}

A{Ο1} / A{Ο2} = 9

A{Ο1} = 9A{Ο2}

Therefore, the area of the circle {1} is 9 times greater than circle {2}.
