Answer:

20

Step-by-step explanation:

When two numbers vary inversely, they always multiply to the same product, in this case, it is 80, because it is 8 x 10(product of two known values of p and q). This means, for q = 4, we can write:

p * 4 = 80

This means that p is equal to 20.

The value of p is 20 when q=4

Let there are two variables p and q

Then, p and q are said to be directly proportional to each other if

p = kq

where k is some constant number called constant of proportionality.

When two numbers vary inversely, then the will always multiply to the same product,

Here it is 80, because it is 8 x 10

Then product of two known values of p and q).

This means, for q = 4, we can write:

p x 4 = 80

This means that p is 20.

Answer:

$13,648.14

Step-by-step explanation:

Cost of a used car = $13420

Sale discount = 10%

Sales tax = 13%

Amount of discount = 10% of $13420

= 10/100 * $13420

= $1,342

Amount of sales = Cost of a used car - Amount of discount

= $13420 - $1,342

= $12,078

Amount of tax = 13% of sale amount

= 13/100 * $12,078

= 0.13 * $12,078

= $1,570.14

Total sale price = Amount of sales + Amount of tax

= $12,078 + $1,570.14

= $13,648.14

Answer:

-4/3

Step-by-step explanation:

Before we can get the slope of AD, we need to get the coordinate of point D.

D(X, Y) = (5-3/2, 5-1/2)

D(X, Y) = (2/2, 4/2)

D(X, Y) = (1, 2)

Next is to get the slope of line AD

Slope = y2-y1/x2-x1

Slope= -2-2/4-1

Slope of AD = -4/3

Hence the slope of AD is -4/3

Answer:

33/4

Step-by-step explanation:

Let n = number

2/3 * n = 11

Multiply each side by 3/2

3/2 * 2/3 n = 11 * 3/2

n = 33/2

We want to find 1/2 of n

1/2 * 33/2 = 33/4

Answer:

Saturday.

Step-by-step explanation:

To answer the above question, we must recognise that Tuesday appears once every 7 days.

If today is Tuesday, 31 days ago will be obtained as follow:

31/7 = 4 remainder 3

Thus

31 = (7 × 4) + 3

31 = (28) + 3

Thus, the 28th day is Tuesday. If we count 3 days back from Tuesday, the day will be Saturday.

Therefore, the magician made his wife disappear on Saturday.

Answer:

65.7

Step-by-step explanation:

Given the population of West Algebra can be modeled by the equation

P = 30. 1.04^T

If T is the number of years since 2000 and P is  the population in millions, in 2020, T = 2020 - 2000 = 20

Substitute T = 20 into the expression and get T

P = 30. 1.04^20

P = 30(2.1911)

P = 65.73

Hence the amount of people that will be there in 2020 is 65.7million people

Answer:

k is the smallest number such that 2(to the k)>n

Step-by-step explanation:

Frequency distribution is defined as the number of times the value occurs. It contains the class interval as well as the corresponding frequencies. A pivot table is used to represent the frequency distribution.

The "2 to the k" rule states that 2 to the power k should be less than equal n, where n is the number of the given data points. It should be the smallest number.

Thus the answer is : k is the smallest number such that 2(to the k)>n.

p(x) × q(x)

= (3x² - x + 1) × (2x² + 3x - 2)

= 6x⁴ + 9x³ - 6x² - 2x³ - 3x² + 2x + 2x² + 3x - 2

= 6x⁴ + 7x³ - 7x² + 5x - 2

Answer:

x=15

Step-by-step explanation:

The Consecutive Interior Angles Theorem basically states that two interior angles (neither adjacent nor opposite) are supplementary, which means they add up to 180 degrees. That means that ∠2+∠4=180. ∠2=2x+10 and ∠4=4x=80. Using the Substitution Property, we get 2x+10+4x+80=180. Do some fun algebra:

6x+90=180

6x=90

x=15

Remember and know your properties and theorems. They will help you and will make proofs a LOT easier (and a LOT more fun).

Answer:

m = -1/3

Step-by-step explanation:

To get the slope of the line, we identify two points on the line and use the slope formula

We can have the points (-2,3) and (1,2)

We have the slope formula as;

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

m = (2-3)/(1 + 2) = -1/3
