Answer:

8.9

Step-by-step explanation:

1. DE:BC=AD:AB

2. AD=AB+BD, but according to the conditions AB=5, then

AD=5+BD.

3. after the substitution DE=16; BC=9; AB=5 and AD=5+BD into the formula:

16:9=(5+BD):5;

[tex]\frac{16}{9} =\frac{BD+5}{5};[/tex]

BD=80/9 - 5≈3.9.

4. if AD=AB+BD, then AD=5+3,9=8,9

8.9 is your answer to the question

Answer:

store w: c = $14

store z: c = 0.60n + 2

Step-by-step explanation:

i had a similiar question with different numbers so i just changed the numbers for ur equation :)

The equation to make for the cost to be the same at both stores would be; 14 = 0.60n + 2

An equation is an expression that shows the relationship between two or more numbers and variables.A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We are given that cost of making copies at Store W is ​$14 regardless of the number of copies. And the cost of making copies at Store Z is 60 cents per copy plus a ​$2 charge for the use of the machine.

The total​ cost, c, of making n copies at either store can be represented by an equation as;

The store w:

c = $14

The store z:

c = 0.60n + 2

Solving for n then

14 = 0.60n + 2

0.60n = 12

n = 20

Answer:

Its D (-2,-5)

Step-by-step explanation:

Point A rest in the (negative, negative) and you have to go along the x first which is -2 and down which is -5 so your answer in (-2,-5)

Also I just did this and is was correct.

Hope this helps!

The coordinates of point A is (-2,-5).

Each point can be identified by an ordered pair of numbers; that is, a number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate. Ordered pairs are written in parentheses (x-coordinate, y-coordinate). The origin is located at (0,0).

The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane.

From the given graph, we can see

Point A rest in the (negative, negative) and you have to go along the x first which is -2 and down which is -5 so your answer in (-2,-5)

Answer:

A sample of 164 is needed.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1-0.8}{2} = 0.1[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].

So it is z with a pvalue of [tex]1-0.1 = 0.9[/tex], so [tex]z = 1.28[/tex]

Now, find the margin of error M as such

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

How large of a sample is required to estimate the mean usage of water

We need a sample of n.

n is found when [tex]\sigma = 1.4, M = 0.14[/tex]. So

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

[tex]0.14 = 1.28*\frac{1.4}{\sqrt{n}}[/tex]

[tex]0.14\sqrt{n} = 1.28*1.4[/tex]

[tex]\sqrt{n} = \frac{1.28*1.4}{0.14}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.28*1.4}{0.14})^{2}[/tex]

[tex]n = 163.84[/tex]

A sample of 164 is needed.

Answer:

Step-by-step explanation:

Hey there!

We simply have to do 182/2.8, and you will get the area (65m^2).

We know that the formula for area is length x width, and the formula for volume is length x width x height. In the volume formula, we can see it can also be area x height to get volume. So, we know that area x height = volume, right? And in this equation, we are given volume and height. If          V = ha, with V = volume; h = height; a = area, we can divide "h" on both sides, and we get V/h = a, or volume divided by height is area. To solve for the above equation, we can plug the numbers in the formula: 182/2.8 = a, or 65 = a.

Answer: 2/7

Step-by-step explanation:

You take the top numbers and multiply them and then take the bottom numbers and multiply them and then you simplify.

1/3 × 6/7 = 6/21 = 2/7

To multiply fractions we'll multiply numerator with the numerator and denominator with the denominator and simplify (1/3 × 6/7) = 6/21 = 2/7.

Fractions are written in p/q form,where q ≠ 0 as it would become undefined.Fractions are of two types one is proper fraction and another one is improper fraction.

A fraction is is the form of numerator divided by the denominator.

To multiply two or more fraction we simply have to multiply numerator with the numerator and denominator with the deominator to combine them into one fraction and then we simplify the combined fraction until both the numerator and the denominator has HCF of 1.

Given (1/3 × 6/7) which is,

= 6/21.

= 2/7.

Answer:

19 boxes of tomatoes

Step-by-step explanation:

If she starts with 7 boxes of tomatoes and she picks 2 more each day for 6 days then you can multiply 2 by 6 and get 12 tomatoes then you add the 7 boxes she originally started with and you get 19 boxes of tomatoes.

The number of boxes Nancy had after 6 days is 19, the equation representing the given phrase is y = 2x + 7, and the graph is attached below.

A collection of objects is arranged in a graph, where some object pairings are conceptually "linked." Each pair of connected vertices is referred to as an edge, and the objects are represented by mathematical abstractions known as vertices.

Given:

Nancy has 7 boxes of tomatoes,

Each day, she picks another 2 boxes,

The equation which will represent the above phrase is shown below,

Total number of tomatoes = The number of tomatoes she already had + number of days × each day's tomatoes picked by Nancy,

Assume the total number is y and the number of days is x then,

y = 7 + 2 × x

y = 2x + 7

Put the value of x = 6,

y = 2 × 6 + 7

y = 12 + 7

y = 19

Thus, she has a total of 19 boxes of tomatoes after 6 days.
