3:5 (or 3/5)

Step-by-step explanation:

The ratio of area is equal to (ratio of perimeters)^2

That means...

(18:50) = (a:b)^2

This simplifies to:

(9:25) = (a:b)^2

Which means...

3:5 = a:b

Answer:

y= -6x^3

Step-by-step explanation:

Look at the points on the graph and plug into the equations

when x = -1, y must equal 6

(-1)^3 = -1

(-1) x (-6) = 6

y= -6x^3, equation represents the transformed function.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

Here, we have,

Look at the points on the graph and plug into the equations

when x = -1, y must equal 6

(-1)^3 = -1

(-1) x (-6) = 6

Hence, y= -6x^3, equation represents the transformed function.

Answer:

80 ways

Step-by-step explanation:

The first thing is to apply the Fundamental Counting Principle with two groups of items, in this case the multiplication rule is used.

In this case, what we should do is that, for every 1 main course there are 8 appetizers, but there are 10 main courses therefore:

8 * 10 = 80

There are 80 ways to combine appetizers and the main course

Final answer:

A person can order from a restaurant 120 different two-course meals using the Fundamental Counting Principle, as there are 10 appetizers and 12 main courses to choose from.

Explanation:

The question is asking how many different two-course meals can be ordered if a restaurant offers 10 appetizers and 12 main courses. According to the Fundamental Counting Principle, if there are separate events and the first event can occur in 'm' ways and the second in 'n' ways, then the events together can occur in a total of m x n ways.

Using this principle:

Number of ways to select an appetizer = 10

Number of ways to select a main course = 12

Therefore, the total number of two-course meal combinations = 10 appetizers x 12 main courses = 120 combinations

So, a person can order 120 different two-course meals from this restaurant.

Answer:

210

Step-by-step explanation:

Multiply 150 by 40% (0.4) and then add that to the initial value (150)

150x0.4=60

150+60=210

I did the math and it ended up being 210. You just take 40 percent of 150 and add it to 150.

The circumference of a circle is calculated based on its diameter using the formula C = πd. Replace 'd' with the value of the circle's diameter to obtain an expression representing the circumference.

The formula for the circumference C of a circle with a diameter d is given by C = πd, where π (Pi) is approximately 3.14. To write an expression to represent the circumference of a specific circle, simply replace the term 'd' with the actual diameter of the circle. For example, if the diameter of the circle is 10 units, then the expression for the circumference would be C = π * 10 or C = 3.14 * 10, hence the circumference C of the circle would be about 31.4 units.

ed2022

Final answer:

The 'n' in the annuity formula stands for Option C. the total number of payments or periods, essential for calculating the present value of equally spaced payments over time.

Explanation:

The letter 'n' in the Present Value of an Ordinary Annuity formula represents the total number of payments or periods over which the payments are made. When calculating the present value of an annuity, the formula accounts for each payment being discounted by the interest rate per period. Therefore, the present value of an annuity is calculated by summing up the values of all the payments, each discounted back to their present value.

An example of using the formula could relate to calculating the present value of a series of fixed mortgage payments over time. If the monthly interest rate is 'r', and there are 'n' total payments (for instance, 360 payments for a 30-year mortgage), the present value would account for each payment by discounting it over the number of periods to reflect the time value of money.

The solution is as follows

First, put both expression in different brackets

[tex](3x-9)(6x^2-2x+5)[/tex]

Expand [tex](6x^2-2x+5)[/tex] bracket by [tex](3x-9)[/tex]

To do that. we first multiply [tex](6x^2-2x+5)[/tex] by 3x then by -9. This is done as follows

[tex]3x (6x^2-2x+5) - 9(6x^2-2x+5)[/tex]

Now, we proceed to opening the bracket

[tex](3x * 6x^2-3x * 2x+3x *5) - (9* 6x^2-9* 2x+9* 5)[/tex]

[tex](18x^3 -6x^2+ 15x) - (54x^2 - 18x +45)[/tex]

Open both brackets

[tex]18x^3 -6x^2+ 15x -54x^2 + 18x -45[/tex]

Collect like terms

[tex]18x^3 -6x^2 -54x^2 + 15x + 18x -45[/tex]

[tex]18x^3 -60x^2 + 33x - 45[/tex]

Hence, the product of [tex]3x-9[/tex] and [tex]6x^2-2x+5[/tex] is [tex]18x^3 -60x^2 + 33x - 45[/tex]

b. Given

Are their products equal?

To check if they are equal or not, we find the product of both and compare the solutions

We've already solved for [tex]3x-9[/tex] and [tex]6x^2-2x+5[/tex] in the (a) part of this exercise, so we move to the product of [tex]9x-3[/tex] and [tex]6x^2-2x+5[/tex]

The solution is as follows

First, put both expression in different brackets

[tex](9x-3)(6x^2-2x+5)[/tex]

Expand [tex](6x^2-2x+5)[/tex] bracket by [tex](9x-3)[/tex]

To do that. we first multiply [tex](6x^2-2x+5)[/tex] by 9x then by -3. This is done as follows

[tex]9x (6x^2-2x+5) - 3(6x^2-2x+5)[/tex]

Now, we proceed to opening the bracket

[tex](9x * 6x^2 - 9x * 2x + 9x *5) - (3* 6x^2 - 3 * 2x + 3* 5)[/tex]

[tex](54x^3 - 18x^2+ 45x) - (18x^2 - 6x +15)[/tex]

Open both brackets

[tex]54x^3 - 18x^2+ 45x -18x^2 + 6x -15[/tex]

Collect like terms

[tex]54x^3 - 18x^2 -18x^2 + 45x + 6x -15[/tex]

[tex]54x^3 - 36x^2 + 51x -15[/tex]

Now, we compare both answers

Is

[tex]18x^3 -60x^2 + 33x - 45[/tex]

equal to

[tex]54x^3 - 36x^2 + 51x -15[/tex]

No, they're not.

Reason is that, for both expressions to be equal, we must have the same expression after expanding both of them

Answer:

105 = (w+8) *w

w = 7 cm

l = 15 cm

Step-by-step explanation:

Area of a rectangle is

A = l*w

l = w+8

105 = (w+8) *w

Distribute

105 = w^2 +8w

Subtract 105 from each side

105-105 = w^2 +8w -105

0 =w^2 +8w -105

Factor

What 2 number multiply to 105 and add to 8

15*-7 = -105

15-7 = 8

(w+15) (w-7) =0

Using the zero product property

w+15 =0               w-7 =0

w=-15                      w=7

impossible

not negative

w =7

l = 15

Answer:

Width: w

Length: w + 8

w(w + 8) = 105

w² + 8w - 105 = 0

w² + 15w - 7w - 105 = 0

w(w + 15) - 7(w + 15) = 0

(w + 15)(w - 7) = 0

w = -15, 7

width = 7cm

length = 7+8 = 15cm

Answer:

the above images shows the answer to the question

The probability that both Jim and Sue will pass the driving test is 0.42. The probability that only one of them (either Jim or Sue) will pass the driving test is 0.46.

This question falls under probability in Mathematics. To solve for these probabilities, we multiply the individual probabilities together.

a) The probability that both Jim and Sue will pass the driving test is found by multiplying the two probabilities together: 0.7 (Jim's probability) * 0.6 (Sue's probability) = 0.42. So, the probability that both will pass is 0.42.

b) The probability that only one of them will pass the driving test is found by adding the probability of the two independent events: Jim passes and Sue fails, or Sue passes and Jim fails. Jim passing and Sue failing would be 0.7 * (1 - 0.6) = 0.28. Sue passing and Jim failing would be 0.6 * (1 - 0.7) = 0.18. Adding these together, the probability that only one of them will pass is 0.28 + 0.18 = 0.46.
