Answer:
360 square meters.
Step-by-step explanation:
You can split the polygon into three rectangles. Then you just have to figure out the area of each rectangle and add them together. The first rectangle has length of 12 and height of 10 so area of 120. The second rectangle has length of 32 and height of 6 so area of 192. The third rectangle has length of 8 and height of 6 so are of 48. 120 + 192 + 48 = 360

Amanda pours 3/4 of her water into Barbara’s empty bottle. Barbara then pours 3/5 of her water into Charlie’s empty bottle. Charlie then pours 1/2 of his water into David’s empty bottle. If David now has 18 ounces of water, how many ounces does Amanda still have?
Answer:
20 ounces of water
Step-by-step explanation:
Work backwards. David has 18 ounces, which is half of Charlie's. So, Charlie had 18•2=36 ounces. That was 3/5 of Barbara's water, so Barbara had 60 ounces. That is 3/4 of Amanda's water, so Amanda had 80 ounces. To find how much Amanda had left subtract 60 from 80 to get 20.

please help!!
Answer:
13
Step-by-step explanation:
Answer:
c=13
Step-by-step explanation:
Hey There!
c+11=24
When looking at this problem you want to get the variable on one side (c) and the constant on the other ( any whole number)
as you can see we need to get rid of the 11 on the left side
to do that we subtract 11 but whatever you do to one side you have to do to the other side
11-11 cancels out
24-11=13
so we can conclude that
c=13

how to calculate the quotient of 286 and 11
Answer:
Answer: (286/11) ÷ 2 = 13
Step-by-step explanation:
The quotient of 286 and 11 is given by the equation A = 26
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first number be represented as x
Now , the value of x = 286
Let the second number be represented as y
The value of y = 11
Let the quotient be represented as A
The value of A is given by the equation ,
A = x/y
Substituting the values in the equation , we get
A = 286/11
The value of A = 26
Therefore , the value of A is 26
Hence , the equation is A = 26

A box has a length of 7 centimeter so,a width of 2 centimeters, and a height of 4 centimeters.The bottom layer of the box is filled with 14 unit cubes that measure one centimeter on each side.which expression represents the volume of the box in cubic centimeters
Answer:
V = (14)(4) V = 56cm³
Step-by-step explanation:
The Volume is Base times Height
We are given that the base is 7cm by 2cm.
That is 14 cm² (The cubes each have volume of 1 cm³, so the volume of that bottom row is 14cm³, technically, but ignore that for now.)
To find the volume, multiply the base times the height.
V = 14cm² × 4cm
V = 56cm³
A map has a scale of 2 inches : 5 miles. What is the actual distance if the map is 1 ft 2 in?
===========================================================
Work Shown:
1 ft = 12 inches
1 ft, 2 inches = 12 inches + 2 inches .... add 2 inches to both sides
1 ft 2 inches = 14 inches
Now we'll use the scale ratio to help find the answer
(2 inches)/(5 miles) = (14 inches)/(x miles)
2/5 = 14/x
2x = 5*14
2x = 70
x = 70/2
x = 35
The distance between the two locations is 35 miles.

Answer:
Vertex: (-1, 4)
Maximum: f(-1) = 4
Increasing: (-∞, -1)
Decreasing: (-1, ∞)
Step-by-step explanation:
The equation can be written in vertex form by "completing the square."
First factor out the leading coefficient from the x-terms.
f(x) = -(x² +2x) +3
Then add the square of half the x-coefficient inside parentheses. Add the opposite of that amount outside parentheses.
f(x) = -(x² +2x +1) +3 +1
Write in vertex form.
f(x) = -(x +1)² +4 . . . . . . . compare to a(x -h)² +k
You can see that the vertex is (h, k) = (-1, 4), and that the vertical scale factor 'a' is negative. This means the vertex is the maximum and the parabola opens downward.
The function will be increasing to the left of the maximum, decreasing to its right.

Vertex: (-1, 4)
Maximum: f(-1) = 4

Answer:
x = 16
m<R = 34°
Step-by-step explanation:
▪︎Its an isoceles triangle, so the two opposite angles are equal. m<S = <T.
▪︎So, you write them equal to each other and solve the linear equation to find x.
▪︎Substitute the x value into any of the angles and multiply by 2, (as they are equal) to find the sum, which is 146°.
▪︎Sum of all angles in a triangle is 180°,so
146° + m< R =180°
▪︎than minus 146° from 180°.
▪︎And you will have your answer.
