1/4(12k-4) ''simplify''

Answer:

a)A=4B

b)A=20

c)B=9

If it is directly proportional it means that A=kB.

you can substitute the numbers to find k.

12=k3

k=4

so the formula is A=kB.

For part b and c it is just substitution

Considering the expression in this problem, it is found that:

a) The part of the expression that gives the amount of taxes that has to be paid is: 0.096(14f).

b) The expression would be of: C(f) = 15f + 0.096(15f).

The expression for the total cost in this problem is presented as follows:

C(f) = 14f + 0.096(14f).

The meaning of each term is given as follows:

If the cost per square foot was of $15 instead of $14, the complete expression would be as follows:

C(f) = 15f + 0.096(15f).

That is, the two instances of 14 in the equation were replaced by 15.

As RS=TU and ST=UR by distance formula, The given quadrilateral RSTU is rectangle and The diagonals RT=US so they are equal and bisect each other at right angle.

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason. Rectangles can also be referred to as parallelograms because their opposite sides are equal and parallel. An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposite sides. A rectangle has two dimensions—length and width—because it is a two-dimensional shape. The rectangle's longer side is its length, and its shorter side is its width.

Here,

Calculate the length of sides by distance formula.

RS=√(y2-y1)²+(x2-x1)²

=√(2-4)²+(-2-2)²

=√4+8

=√(12

=2√3 units

ST=√(y2-y1)²+(x2-x1)²

=√(0-2)²+(-1-(-2))²

=√(4+1)

=√5 units

TU=√(y2-y1)²+(x2-x1)²

=√(2-0)²+(3-(-1))²

=√(4+8)

=√12

=2√3 units

UR=√(y2-y1)²+(x2-x1)²

=√(4-2)²+(3-2)²

=√(4+1)

=√5 units

RT=√(y2-y1)²+(x2-x1)²

=√(0-4)²+(-1-2)²

=√(16+9)

=√25

=5 units

US=√(y2-y1)²+(x2-x1)²

=√(2-2)²+(-2-3)²

=√(0+25)

=√25

=5 units

Because the given quadrilaterals, RS=TU and ST=UR, are rectangles and the diagonals, RT=US, are equal and at right angles to one another, according to the distance formula.

Answer:31.2

Step-by-step explanation:

According to the statistics presented in the bar graph of responders of four locations per 40 potential customers, the average number of places chosen per potential client is 2.5.

We are given;

Total number of potential customers =40

From the bar graph number of respondents are following;

At grocery stores = 40

At drugstores respondents = 32

At health food stores = 8

At big box stores = 20

So,

The average number = Total number of respondents / Total number of potential customers

The average number = (40 + 32 + 8 + 20) / 40

The average number = (100) / 40

The average number = 2.5

Thus, according to the statistics presented in the bar graph of responders of four locations per 40 potential customers, the average number of places chosen per potential client is 2.5.

Answer:

Step-by-step explanation:

You want the cost of a shirt when the cost of 21 shirts plus a $40 setup fee is $187.

The total cost of the order is the sum of the setup fee and the extended cost of the shirts.

  cost = (setup fee) + (number of shirts) × (cost per shirt)

  187 = 40 + 21 × (cost per shirt)

Subtracting 40 gives ...

  147 = 21(cost per shirt)

Dividing by 21, we have ...

  7 = cost per shirt

Each T-shirt costs $7.

Out of the next 5 visitors, 2 will be asked to attempt the survey. (A) yes, because 2 out of 5 is equal to 40%.

It is given the probability that the randomly selected person is asked to participate in an online survey is 0.4

This means that there is a 40% chance of a visitor being asked to join the survey.

Probability of an event = no. of favorable outcomes / total no of outcomes

P(E) = n(E) / n

Therefore, if the number of visitors to the website is 5,

n = 5

P(E) = 0.4

Hence,

n(E) / 5 = 0.4

or, n(E) = 0.4  X  5

or, n(E) = 2

Therefore, out of the next 5 visitors, 2 will be asked to participate in the survey.

The total number of points scored by the other 7 team members in Euclid high school's last basketball game is 11.

For the given question.

Let 't' be the total points scored.

Alexa = 1/4 t.

Brittany = 2/7 t

Chelsea = 15

Let 'x' be the points scored by remaining 7 team.

Thus, the two variable equation becomes.

1/4 t +  2/7 t + 15 + x = t   .....eq 1

Where, x ≤ 14 ( for 7 terams)

Simplifying eq 1.

15 + x = 13/ 28 t

28x + 28 = 13 t

Now, t must be divisible by 28.

Let t = 28 u, u ≥ 0 and divisible by 28.

Thus,

x + 15 = 13u.

Then, u = 2( t = 56) has been the only candidates for which x = 11.
