Answer:

1 day

Step-by-step explanation:

Cuz if 15 bears are made in 10 min you multiply by 60 cuz 60 min = 1 hour, so 15 times 60=900 then if the work 8 hr a day then u multiply 900 by 8 to get 7200 bears

The number 16 must be added to the equation for making it a perfect square.

We must have the idea of algebraic identities to solve this problem. The identity of the sum of square of two variables is given below.

We know that [tex](a+b)^{2}= a^{2} +2ab+b^{2}[/tex].

So make a perfect square the equation must be of the form of [tex]a^{2} +2ab+b^{2}[/tex]

Given, [tex]x^{2} +8x=4[/tex]

     ⇒ [tex]x^{2} +2*4*x+ 4^{2}=4+4^{2}[/tex]

     ⇒  [tex](x+4)^{2}=20[/tex]

So, to complete the square we have added 16 to both the sides of the equation and now it is in the form of [tex](a+b)^{2}[/tex].

The required number to be added is 16.

The ordering of the numbers from the smallest to the biggest will be -3, -✓5, -1.5, 7/2, ✓16.

It should be noted that we have to arrange the numbers from.the smallest to the biggest.

The numbers include:

-√5 = -2.24

-, 3,

-1.5,

√16 = 4

7/2 = 3.5

Therefore, the ordering of the numbers will be -3, -✓5, -1.5, 7/2, ✓16.

Answer:

r = -25

Step-by-step explanation:

slope is change in "y" over change in "x"

so whatever your change in "x" is between the two points, the change in "y" needs to be in proportion to the slope of -3.

Here the change in "x" is +10, and to make the proportion of the slope equal to -3, the change in "y" needs to be -30.

Starting from the "y" coordinate of 5, a change in "y" of -30 will give you r = -25

So the two points are (-5, 5) and (5, -25)

Answer:

84%

Step-by-step explanation:

In order to calculate this, we first need to calculate the total weight of the puppy on the last visit. We do this by adding the weight that the puppy gained each visit like so...

19oz + 9oz + 7oz = 35oz

Now that we have the final weight we simply divide the final weight by the initial weight of the puppy in the first visit. Then we subtract 1 from that value and multiply by 100 to get the percentage increase.

35oz / 19oz = 1.84

1.84 - 1 = 0.84

0.84 * 100 = 84%

Finally, we can see that the puppy had an 84% increase since the first visit.

step-by-step explanation:

it's a lot of work

because the question said they are all positive numbers and if it has the sign of minus and minus is a negative sign.

√ 3 can be classified as a non negative square root of the number 3 which is also a real and irrational number.

We are given a number √ 3.

We need to classify the number.

First we can see that, this is the non negative square root of the number 3.

That is when we multiply √ 3 two times, we get the number 3.

Also, we can see that, it will be an irrational number as it will be non terminating and non repeating number.

That is it will be a real irrational number.

Therefore, we get that, √ 3 can be classified as a non negative square root of the number 3 which is also a real and irrational number.
