Answer:

I believe its 112.26?

Step-by-step explanation:

Answer:

a.) The sum of the weights of the two in insects is 0.0031 grams. (0.0031 grams)

b.) The fly is 0.0013 grams heavier than the gnat. (0.0013 grams)

Step-by-step explanation:

2.2 * 10^-3 = 2.2 * 1/1000 which is 2.2/1000.

9 * 10^-4 = 9 * 1/10000 = 9/10000

To add 9/10000 to 2.2/1000 we have to find the common denominator, which will be 10000.

So we do:

2.2/1000 * 10/10 = 22/10000

9/10000 + 22/10000 = 31/10000 = 0.0031.

The sum of the weights of the two in insects is 0.0031 grams.

To find how much heavier the fly is than the gnat we do:

22/10000 - 9/10000 = 13/10000 = 0.0013

The fly is 0.0013 grams heavier than the gnat.

Answer:

x               y

4/3            2

8/3           10/3

22/3        24/3

Step-by-step explanation:

Substitute y with 2 for the first problem

2=x+2/3

Subtract 2/3 on both sides:

4/3

Thus:

x               y

4/3            2

Now Substitute x with 8/3 for the second problem

y=8/3+2/3

Add:

y=10/3

Thus:

x               y

8/3           10/3

Now Substitute x with 8/3 for the third problem

y=22/3+2/3

Add:

y=24/3

Thus:

x               y

22/3        24/3

Thus the Full equation is:

x               y

4/3            2

8/3           10/3

22/3        24/3

Answer:

x           y

4/3        2

8/3        10/3

22/3      8

Step-by-step explanation:

y=x+2/3

2=x+2/3

2-2/3=x+2/3-2/3

6/3-2/3=x

4/3=x

y=x+2/3

y=8/3+2/3

y=10/3

y=x+2/3

y=22/3+2/3

y=24/3

Answer:

7.5 gallons

Step-by-step explanation:

2.5/5+x=0.2

This question is based on the concept of solving an  equation. Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.

Given:

5 gallons of 50% acid solution to get a 20% solution.

According to question,

Let  it be x gallons of water should be added to 5 gallons of 50% acid solution to get a 20% solution.

Now, forming the equation, we get,

 0.50 ( 5 )  =  0.20  ( x + 5 )

Simplifying the equation.

We get,

2.5 = 0.2x + 1

1.5 = 0.2 x

x = 7.5

Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.

Answer:

The distance between the 2 points is about 13.6

Step-by-step explanation:

Picture the 2 points on a graph, and then look at the distance between them as the hypotenuse of a right triangle. You can easily find the length of the legs of that triangle, and with those legs, you can use the pythagorean theorem to calculate the length between the points.

The length of one leg is the distance between the 2 x-coordinates, between -5 and 3, so that's 8.

[tex]3--5=3+5=8[/tex]

The length of the other leg is the distance between the y, between 2 and -9.

[tex]-9-2=-11[/tex]

That's just a distance of 11, as there's no such thing as negative distance.

Now we have the legs, so we can find the hypotenuse:

[tex]a^2+b^2=c^2\\8^2+11^2=c^2\\64+121=c^2\\c^2=185\\c\approx13.6[/tex]

Answer:

a. Meg needs to find the part

b. Steve needs to find the percent.

Step-by-step explanation:

A. Does Meg need to find the part, the whole, or the percent.

Meg already knows the whole and the percent.

The whole is the entire number of dogs seen: 16 dogs.

The percent is 50%.

Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.

And she can do with a simple operation:

Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.

B. Does Steve need to find the part, the whole, or the percent.

He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).

Then he needs to find the percent, which he can do using the next operation:

Percent = (part / whole) × 100 = (7/35)×100 = 20%

Step-by-step explanation:

Part 1:

Meg needs to find the whole as 50% of the dogs = 5 therefore 100% equals 10 dogs.

Part 2:

Steve saw 50% out of two dogs meaning that he only saw 1 dog that is a boxer.

Answer:

-3/x^8

Step-by-step explanation:

First, we simplify -30/10 which will be -3.

Next, we simplify x^9/x^17 which will be x^-8, since when dividing exponents, you subtract them. Sorry if this sounds confusing, but if this helps you better understand it, then here you go: I mean that y^n/y^z = y^(n-z).

x^-8 = 1/(x^8), and to find our answer, we multiply this by -3 to get an answer of:

-3/x^8
