A, B and C
Answers
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.

Principal: $2,500, Time: 2 years; Interest: $450
Answers
Answer:
36%
Step-by-step explanation:
I/Pt = r to get your rate.
I = Interest amount paid in a specific time period (month, year etc.)
P = Principle amount (the money before interest)
t = Time period involved
r = Interest rate in decimal
$450 ÷ 2,500(2)=36%

You roll a six-sided number cube and flip a coin. What is the probability of rolling a number less than 2 and flipping heads? *
1/12
1/4
6/2
2/6
Answers
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! :)

What is Division method?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

Answers
I could figure out but I am not going to sorry:(
Answer: There are 4 tubes of paint she purchased.
Step-by-step explanation:
Since we have given that
Amount spend on tubes of paint and brushes for an art project = $16
Cost of each tube of paint = $3
Cost of each brush = $0.50
Let the price of tube of paint be 'x'.
Let the price of brush be '2x'.

A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram:
rectangle with length of x ft and width of x minus 4 ft, right triangle inside labeled stage with height of x minus 4 ft and base of 6 ft, rectangle inside labeled closet with length of 7 ft and width of 2 ft, the rest of the rectangle is labeled floor
Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).
A = x(x − 4) + 0.5(6)(x − 4) + 2(7)
A = x(x − 4) − 0.5(6)(x − 4) − 2(7)
A = x(x − 4) − (6)(x − 4) − 2(7)
A = x(x − 4) + (6)(x − 4) + 2(7)
Answers
Answer: A=x(x-4)-0.5(6)(x-4)-2(7)
Step-by-step explanation:
A=x(x-4)-(0.5(6)(x-4) + 2(7))
A=x(x-4)-0.5(6)(x-4)-2(7)
Answer:
A = x(x − 4) − 0.5(6)(x − 4) − 2(7)

A gift box has the dimensions of 16 inches by 11 inches. What is the perimeter of the box in feet?
Answers
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.

Step-by-step explanation:
At the point where the two triangle meet, the north angle is 115°, so the south one will be 115°, because they're alternate angles. This means that to get the other two angles left, you must subtract the two angles that weren't in the triangles on that point = 360° - (115 x 2) = 130°. 130° is the total of the two angles on the point in the two triangles. Then you just subtract the two angles you have for each triangle from 180° to get the last two angles
Is this supplementary, Complementary, a vertical angle, or none of the the above?
Answers
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".

Answers
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

Answers
Answer:
c
Step-by-step explanation:
The percent of discount on the shirt will be 30%.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol '%' is used to symbolize it.
The percentage is given as,
Percentage (P) = [Initial value - Final value] / Initial value x 100
A $40 shirt now selling for $28.
Then the percent of discount on the shirt will be
The final value of the shirt is $18 and the initial value of the shirt is $40.
Percentage (P) = [(40 - 28) / 40] x 100
Percentage (P) = [12 / 40] x 100
Percentage (P) = 0.30 x 100
Percentage (P) = 30%
Thus, the percent of discount on the shirt will be 30%.
