Dara spends $16 on tubes of paint and disposable brushes for an art project. Each tube of paint costs $3, and each disposable brush costs $.50. Kara purchases twice as many brushes as tubes of paint. Find the number of brushes and the number of tubes of paint that she purchases.
Use the equations below to find your answers. Show your work.
x = tubes of paint
y= disposable brushes
x + .5y = 16
y = 2x

Answer:

1944

Step-by-step explanation:

The volume of the box is,

⇒ V = 729 inch³

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that;

A cube-shaped box can be made from 486 square inches of cardboard.

Now, We know that;

The surface of a cube is given by the expression,

⇒ S = 6L²

Where, L is the length of the edge of the cube.

Hence, We can formulate;

⇒ S = 6L²

⇒ 486 = 6L²

⇒ L² = 81

⇒ L = 9 inch

Thus, The volume of the box is,

V = L³

V = 9³

V = 729 inch³

Answer:

A

Step-by-step explanation:

(pwease give brainliest :)

Answer:

1/12

Step-by-step explanation:

First, you should already be able to understand that the only number less than 2 on this cube is 1. So, you can understand that there is a 1/6 chance because there is a total of 6 numbers, and out of those, only 1 of those are your answer.

Then, you will note that a coin only has 2 sides, so there is a 50/50 chance of getting heads, or 50%. Now, you will turn that into a fraction, which is 1/2.

Next, you will multiply to make the denominators the same. And what you do to the denominator must happen to the numerator. (1/6 * 2--> 1/12 and 1/2 * 6 = 1/12)

Hope this helps! :)

Answer:

z=12

Step-by-step explanation:

multiply both sides of the equation by 2

12=z

swap the sides of the equation

z=12

Answer:

You move all terms to the left;

6-(1/2z)=0

Domain of the equation: 2z)!=0

z!=0/1

z!=0

You add all the numbers together, and all the variables;

-(+1/2z)+6=0

You get rid of parentheses;

-1/2z+6=0

You multiply all the terms by the denominator;

6*2z-1=0

You multiply elements;

12z-1=0

You move all terms containing z to the left, all other terms to the right;

12z=1

z=1/12

And your answer is: z=1/12

Answer:

12ft. 3in.

Step-by-step explanation:

Perimeter is W+L=P. So add 16 and 11 and you get 27. There are 12 inches in a foot so all you would do is see how many times 12 goes into 27 (twice) and put the remainder as inches. So 12 feet and 3 inches. I hope this helped and I hope I'm right.

Answer:

Supplementary Angle

Step-by-step explanation:

If you add the angles "a" and "b" together you get an angle of 180º.

A supplementary angle is an angle that adds up to 180º.

A complementary angle is an angle that adds up to 90º.

A vertical angle has two lines that intersect (like an "X".

Reciprocal is basically flipping the number!!

1) 7

2) 1/6

3) 8/9

4) 3/10

5) 4/9

6) 5/2

Answer:

a) Set up triangles where the hypotenuse is 16ft (the ladder) and one of the two edges are 1, 2, 3, 4, 5ft (the base of the ladder).  Use a^2 + b^2 = c^2 where a is the base length, c is the hypotenuse and b is the value you are trying to find.

Ex w/ 1ft base:

1^2 + b^2 = 16^2

1 + b^2 = 256

b^2 = 255

b = 15.97ft.

b) Simply take your answers from part a) and add 5.5ft (the height of the girl) to them.

Ex w/ 1ft base:

15.97ft + 5.5ft = 21.47ft

c) Using logic here think about it.  Let's take the 1ft base as the example.  Marissa standing on top of the ladder is 21.47ft.  That's clearly not high enough to reach the cat . . . but what happens if Marissa reaches upwards.  As long as her arms can reach roughly 1.53ft above her head she should be able to reach it.
