Well, 3 * 7 is 21. So 3,000 * 70 is 210,000. This is because of the zeros after 3 and 7, obviously, but more importantly, if it were only 3,000 * 7, your answer would be 210,000.

Ok we know that 3 times 7 is 21 right so all you do is do 3 times 7 in your head then add all the zeros up and you get 
210,000

Find the slope of the line through the given points.(-4,7) and (-1,-3)Is the slope increasing or decreasing?
galina1969 [7]

• The following formula can be used to find the slope of a line:

m=\frac{y_2-y_1}{x_2-x_1}

These points are on the line:

(x_1,y_1);(x_2,y_2)

Given the following points:

\mleft(-4,7\mright);(-1,-3)

Then, you can set up that:

\begin{gathered} y_2=-3_{} \\ y_1=7 \\ x_2=-1 \\ x_1=-4 \end{gathered}

Therefore, substituting values into the formula and evaluating, you get:

\begin{gathered} m=\frac{-3-7}{-1-(-4)} \\  \\ m=\frac{-10}{-1+4} \\  \\ m=-\frac{10}{3} \end{gathered}

• As you can notice, the slope is negative. Therefore, you can determine that it is decreasing.

Therefore, the answers are:

• Slope of the line:

m=-\frac{10}{3}

• It is decreasing.

You want to distribute 7 candies to 4 kids. If every kid must receive at least one candy, in how many ways can you do this?
puteri [66]

Answer:

15

Step-by-step explanation:

lets begin to set up this question. i personally find questions like these easiest when i begin to set up ideas to help my brain process it better, for example:

person a

person b

person c

person d

we know that each (person) must receive at least 1 candy. we also know that we have 7 candies. therefore if we want do draw this out :

person a- 1

person b- 1

person c- 1

person d -1

notice that we now have given away 4 of the 7 candies. now we have 3 candies left. we can simply:

person a- 2

person b-2

person c-2

person d- 1

but, keep in mind that there are still many more ways that we can distribute the candies to other kids. the question we are asked is how may ways can we do this. since i have already illustrated the question, you can either learn how to put this into an equation, or experiment how many variations there are. the answer, either way is 15.

the area of a square garden is 267 ft^2 what is the side length of each side? round your answer to the nearest hundredth place.
aksik [14]

Answer:

  • Side Length=16.34 ft
  • No

Step-by-step explanation:

The area of the square garden=267$ ft^2

Area of a Square of Side length s =s^2

Therefore:

s^2=267$ ft^2\\$Take the square root of both sides\\s=\sqrt{267} \\$Side Lenght, s=16.34 ft (to the nearest hundredth place)

<u>Perimeter</u>

Perimeter of a Square of Side length s=4s

Therefore, the perimeter of the garden =4*16.34=65.36 ft

Since 65 ft < 65.36 ft

Therefore, if you had 65 ft of fencing, it will not be enough to go around and cover the garden.
