Can someone please explain this to me??

Answer:

the answer to your question is 9.73

Answer:

A

Step-by-step explanation:

Because according to my calculations there are supposed to be 5 digits and for the answers for the question A is the only letter with an answer with 5 digits.

My answer was 9.7325(even though the answers is different they still have the same number of digits) and for A it is 9.7324 which is another 5 digits.

Here is why I got 5 digits.

4.0125

5.7200

_______

When we add these we have to add 0er's to 5.72 because it doesn't have enough digits to add so you add zero's to it.

So 5 +0=5  2 +0=2  1 +2=3  0 +7=7  and for our last number 4 + 5=9 and so our answer is ?

9.7325

and the 9 = 1 digit 7=2 digit 3= 3 digits 2= 4 digits and last 5 = 5 digits.

Hope this helps have a great day:)

Answer:

1362

Step-by-step explanation:

so

A=1600(1-0.02)^8

A = total population after 8 years

1600 = initial amount of people

0.02 = percent in decimal

8 = years after 2000

1- = decay

Answer:

none of these

Step-by-step explanation:

none of these is the correct answer because if this is pemdas it would be 24.818

and if it is not pemdas it would still be 3.818.

The way pemdas would be solved is 62 divided by 22 first which is 2.818

and then 2.818 + 22 which= 24.818.

But if your just doing it in order and it isn't pemdas than you would do 22 + 62 which=84 and then 84 divided by 22=3.818

So your answers are wrong I wanted to let you know that is there an option od none of theres or is there more to the question I can help you with.

I hope I can help and that this helps have a awesome day:)

Answer:

 10x+7y = -8

Step-by-step explanation:

Standard form is Ax + By + C = 0 or Ax + By = C.

The first step is everything is multipled by 7, witch gives you 7y=-10x-8.

To solve that, 10x to both sides must be added, to get 10x+7y-8

Explanation:

First we multiply everything by 7 to clear out the denominators.

We get to 7y = -10x - 8

Then add 10x to both sides to arrive at 10x+7y = -8

Standard form is Ax+By = C where A,B,C are integers

In this case we have: A = 10, B = 7, C = -8

Some math textbooks insist that A > 0.

Answer:

[tex]m=1[/tex]

Step-by-step explanation:

Given the following question:

Point A = (-7, -8) = (x1, y1)
Point B = (-5, -6) = (x2, y2)

To find the answer we are going to have to use the formula for slope or rise over run.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{-6--8}{-5--7} =\frac{2}{2}[/tex]
[tex]\frac{2}{2} =1[/tex]
[tex]m=1[/tex]

Which means the slope of the line that passes through the points (-7, -8), (-5, -6) is "1."

Hope this helps.

Step-by-step explanation:

here is the answer. I just took th test

The area of the quilt that will be striped fabric is,

⇒ 420 cm²

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

This figure represents a design being added to a quilt square.

And, Malcolm wants to add this design in a striped fabric to 12 quilt squares.

Now, The figure contain a triangle and a square shape.

Hence, We get;

Area of triangle = 1/2 (Base x Height)

                         = 1/2 (5 x 4)

And, Area of square = side²

                               = 5²

Hence, Total area of figure is,

⇒ 5 × 5 + 1/2 (5 × 4)

⇒ 25 + 10

⇒ 35 square units

Hence, The area of the quilt that will be striped fabric is,

⇒ 35 × 12

⇒ 420 cm²

Answer:

Step-by-step explanation:

When we say "y varies jointly as x and z", we mean that y is proportional to x with some constant of proportionality, and also y is proportional to z with some constant of proportionality. The joint variation means that each "constant" of proportionality will depend on the other variable:

  y = k·x·z

This can be solved for the different variables:

  k = y/(x·z)

  x = y/(k·z)

  z = y/(k·x)

__

  k = y/(x·z) = 30/(3·5) = 2; the equation is y = 2·x·z

  k = 2 (read from the equation); x = y/(k·z) = 80/(2·4) = 10

  y = k·x·z = 4·6·8 = 192; the equation is y = 4·x·z

  k = 3 (read from the equation); z = y/(k·x) = 60/(3·10) = 2

  k = 3/4 (read from the equation); x = y/(k·z) = 48/(3/4·12) = 48/9

[tex]\stackrel{\textit{x-intercept occurs when y = 0}}{\stackrel{y}{0}=\cfrac{x^2-5x+6}{x-2}}\implies 0=x^2-5x+6\implies 0=(x-3)(x-2) \\\\\\ x= \begin{cases} 3\\ 2 \end{cases}\qquad \qquad \stackrel{coordinates}{(3~~,~~0)\qquad (2~~,~~0)}[/tex]

Answer:

7/18

Step-by-step explanation:

If 1/3 of the counters are green that means that 60 counters are 1/3 of the total number of counters. We can multiply 60 by 3 to find the total number (3/3) of counters: 60 × 3 = 180

Next, we can find out how many counters are blue and green by subtracting 60 from 180: 180 - 60 = 120

If there are 20 more red counters than blue counters, we can write this algebraically as x + (x + 20) = 120. x + 20 is the number of red counters and x is the number of blue counters

To find x, simplify the equation:

2x + 20 = 120

2x = 100

x = 50

There are fifty blue counters, therefore there are 70 red counters. The probability of picking a red counter is 70/180 or 7/18.

if Tim has read 10% of the book, that means he still hasn't read 90% of it yet, and we know that that 90% is 45 pages, so say the book has a total amount of pages of "x", which is 100%.

[tex]\begin{array}{ccll} pages&\%\\ \cline{1-2} 45&90\\ x&100 \end{array}\implies \cfrac{45}{x}=\cfrac{90}{100}\implies \cfrac{45}{x}=\cfrac{9}{10} \\\\\\ 450=9x\implies \cfrac{450}{9}=x\implies 50=x[/tex]

A pyramid is a three-dimensional object have one common point at the top. The pyramid will have 34 faces.

A pyramid's base form determines how many faces it has. Since the bases of the prism and the pyramid in this problem are identical, we may utilise the knowledge of the prism to ascertain the number of faces on the pyramid.

Three faces of a prism meet at each vertex. Since there are 99 edges on the prism in this instance, we can divide that number by 3 to get how many vertices there are.

99 ÷ 3 = 33

The pyramid has the same number of edges as the prism since its base is identical to that of the latter. The pyramid does, however, have a second face, which is the base itself.

Therefore, the pyramid has 33 + 1 = 34 faces.
