William has a 26-liter glass tank. First, he wants to put some marbles in it, all of the same volume. Then, he wants to fill the tank with water until it's completely full. If he uses 85 marbles, he will have to add 20.9 liters of of water.

What is the volume of each marble?
How much water is necessary if William uses 200 marbles?

Answer: 0.06/marble | 14 liters

Answers

Answer 1

The volume of the marbles is   26-20.9 = 5.1 l      and there ar e85 marbles

5.1/85 = .06 l/marble

 

then 200 marbles would requrie    .06 l/marble x 200 marbles = 12 liters

so he would only need  26-12= 14 liters of water to fill the tank !

Answer 2

Answer:

14 marbles

Laura is training to run a race. She keeps track of the number of miles she runs. She has been training for 7 weeks, and she has run a total of 63 miles. At what rate has she been running, in miles per week?

Answers

Answer:  9 miles per week

Explanation:

You divide the two values given to get 63/7 = 9.

We can think of it as if it was a ratio 63 miles: 7 weeks. Dividing both parts of that ratio by 7 will turn the "7 weeks" into "1 week".

You can check the answer by multiplying the 9 miles per week with the 7 weeks to get 9*7 = 63 miles total.

9 because when you divide 63 by 7 you get 9 and to check you do 7 multiple by 9

Natalia is moving into a new house. All together, her furniture weighs 2,896 pounds. If it takes 2 trucks to carry all of Natalia's furniture, what is the average weight load on each truck?

Answers

Answer:

If you haven't learned long division yet, try breaking up the number and dividing it by 2 like this:

2000/2=1000

800/2=400

90/2=45

6/2=3

Then, add them up and solve from there: 1000+400+45+3=1400+48=1448

Green is with C, Blue is with A, Orange is with D, Purple is with B

Step-by-step explanation:

Hi!

So, it's been a while since I've done math like this, so the way I solved this was simply by doing the equations themselves and seeing which one matches. I'm sure there is an algebraic way to find which ones match, but this is all I know how to do :)

(By the way...I got the decimals by doing the fraction itself. 1 divided by 4(1/4th)=.25, as an example)

1(left)-7/1/4 is the same as 7/ .25. This is 28.

2(left) 2/3/ 4/5 is the same as .6666666/ .8. This is .83333repeating

3(left) 4/5 / 3/2 is the same as .8/1.5. This is .53333repeating

4(left) 1/4 / 1/7 is the same as .25/.143. This is 1.74(approx.)

1(right) 2/3 x 5/4 is the same as .66666 x 1.25 This is .8333 approx.

2(right) 1/4 x 7 is the same as .25*7. This is 1.75

3(right) 7*4 is 28.

4(right) 4/5 x 2/3 is the same as .8x.66666. This is .533

Now, we can match.

Green is with C.

Blue is with A

Orange is with D

Purple is with B

The first term is, 2d2 its coefficient is 2 .
The middle term is, -3d its coefficient is -3 .
The last term, "the constant", is -2

Step-1 : Multiply the coefficient of the first term by the constant 2 • -2 = -4

Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -3 .

-4 + 1 = -3 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1

Step-4 : Add up the first 2 terms, pulling out like factors :

Step-5 : Add up the four terms of step 4 :

We have,

To simplify the expression [tex]4(3x^2y^4)^3 / (2x^3y^5)^4,[/tex] we can simplify each part separately and then divide.

Let's simplify the numerator first:

[tex](3x^2y^4)^3 = 3^3 * (x^2)^3 * (y^4)^3 = 27x^6y^{12}[/tex]

Now, let's simplify the denominator:

[tex](2x^3y^5)^4 = 2^4 * (x^3)^4 * (y^5)^4 = 16x^{12}y^{20}[/tex]

Now we can divide the numerator by the denominator:

[tex](27x^6y^{12}) / (16x^{12}y^{20})[/tex]

To divide the variables with the same base, we subtract their exponents:

[tex]27/16 * x^{6-12} * y^{12-20}[/tex]

Simplifying further:

[tex]27/16 * x^{-6} * y^{-8}[/tex]

To make the exponents positive, we can move the variables with negative exponents to the denominator:

The simplified expression is [tex]27/(16x^6y^8).[/tex]

4x = 3      divide by 4

x = 3/4 dollars = $.75 per pound

Lucy wants to decorate the curved surface of a trash can that has a radius of 4 in. and a height of 12 in.

What is the area of the curved surface of the trash can she will need to decorate?


A trash can with radius 4 inches and height 12 inches.

Answers

12 in =30 cm

4 in = 10 cm

area of 1 circle= 3.14×10×10= 314 cm²

area of 2 circle= 314×2= 628 cm²

if u unfold the trash can the biggest surface(not the circle) will become a rectangle with two circles(628 cm²)

length of rectangle = circle circumference

= 2×3.14×10

=62.8 cm

area of rectangle= 62.8 × 30 = 1884 cm²
