Calculate the area of each figure.
Answer:
230cm²
Step-by-step explanation:
We can split the shape into 2 parts - the triangle and the rectangle.
The area of the retangle is 10*17cm = 170cm²
The area of the triangle = 1/2 * (22-10) * (17-7)
= 1/2 * 12 * 10 = 60
Therefore the total area is equal to 170+60 = 230cm²
A display case of glitter stickers are marked 15 for $2. If Cathy wants to buy 30 glitter stickers, how much will Cathy spend?
Answer:
$4, 15 x 2=30
2 x 2=4
Answer:
4 dollars
Step-by-step explanation:
We can write a ratio to solve
15 stickers 30 stickers
----------------- = -------------
2 dollars x stickers
Using cross products
15x = 2*30
15x = 60
Divide by 15
15x/15 = 60/15
x = 4
Find the perimeter of the shape shown below.
Answer:
22 cubes
Step-by-step explanation:
Hi! I'm happy to help!
Perimeter is the total length of all the sides.
Let's start out with the top left corner and work our way counterclockwise.
For our first segment, we start from the top left corner and go to the bottom left corner, this is a length of 3, let's start our equation:
3+
Next, we are at the bottom left corner, let's go to the bottom right corner. This is a length of 5. Let's expand our equation:
3+5+
Now we are at the bottom right corner, let's go to the top right corner. This is also a length of 3. Let's add that to our equation:
3+5+3+
Now we are at the top right corner, lets go to the top middle right corner, which is to the left one unit. Let's add this:
3+5+3+1+
Now, let's head down 2 units to the inside of our shape.
3+5+3+1+2+
Move toward the center one unit:
3+5+3+1+2+1+
Move up one unit:
3+5+3+1+2+1+1+
Move left one unit:
3+5+3+1+2+1+1+1+
Move down one unit:
3+5+3+1+2+1+1+1+1+
Move left another unit:
3+5+3+1+2+1+1+1+1+1+
Start heading back up 2 units towards the top left corner:
3+5+3+1+2+1+1+1+1+1+2+
Finally, reach back 1 unit to the top left corner:
3+5+3+1+2+1+1+1+1+1+2+1=
Let's solve:
3+5+3+1+2+1+1+1+1+1+2+1=
8+3+1+2+1+1+1+1+1+2+1=
11+1+2+1+1+1+1+1+2+1=
12+2+1+1+1+1+1+2+1=
14+1+1+1+1+1+2+1=
15+1+1+1+1+2+1=
16+1+1+1+2+1=
17+1+1+2+1=
18+1+2+1=
19+2+1=
21+1=
22
Our perimeter is 22.

Use the graph to find out over what interval f(x) is less than or equal to 0. PLEASE HELP ASAP!!!
Answer:
[-5, 2]
Step-by-step explanation:
We have to find the interval for which f(x) <= 0, the interval is [-5, 2].
You move left 4 units. You end at (-5, -5). Where did you start?
Answer:
(-1,-5)
Step-by-step explanation:
To understand where this point was before the transformation you must first understand the transformation itself. Shifting left is a horizontal translation, this means that it will affect the x-coordinate. The x-coordinate is the first digit in the pair. Therefore, in the case of (3,5), 3 would be the x-coordinate. Additionally, moving left is moving towards the negative, so it is the same as subtracting. Thus, to find where you started, work backward. Do this by adding 4 to the x-coordinate. This means the beginning coordinate was (-1,-5).

On a scatter plot, what is the difference between a positive and a negative correlation
Answer:
Positive correlation means that as the first variable increases, the second variable increases as well. ... Negative correlation would mean that as one variable increases, the second variable decreases. Negative correlation corresponds to points that move down as you go from left to right on your scatter plot

Find the value of x.
9514 1404 393
Answer:
C) 41
Step-by-step explanation:
The angles of the linear pair are supplementary, so you have ...
(x +16)° +123° = 180°
x = 41 . . . . . . . . . . . . . . divide by °, subtract 139
Answer:
x = 41
Step-by-step explanation:
The angles shown are supplementary
Supplementary angles add up to equal 180
This means that x + 16 + 123 = 180
x + 16 + 123 = 180
Solve for x
Combine like terms ( add 16 and 123 )
x + 139 = 180
Subtract 139 from both sides
x = 41

Solve the following problems using equations. Show your working steps clearly.
1. Four years ago, the age of Paul was twice that of John. John is 18 years old now. How old is Paul now?
2. Five bottles of milk cost $4.4 more than four bottles of juice. If one bottle of milk costs $3.2, find the cost of one bottle of juice.
3. Miss Cheung spends 1/8 of her savings on personal ornaments and 5/6 on clothing. If her savings still has $130 left, find the original amount of her savings.
1.
Paul's present age = x
John's present age = 18
Paul's age 4 years ago = x - 4
John's age 4 years ago = 18 - 4 = 14
Also,
Paul's age four years ago was twice that of John's age four years ago.
Therefore,
Paul's age 4 years ago = 2(14)
= 28
Paul's age 4 years ago = x - 4 = 28
x - 4 = 28
x = 28 + 4
x = 32
Therefore, the present age of Paul is 32.
2.
Cost of one bottle of milk = $3.2
Cost of five bottles of milk = $3.2 × 5 = $15
Cost of four bottles of juice = $15 - $4.4
= $10.6
Cost of one bottle of juice = x
= Cost of four bottles of juice
4
= 10.6
4
= 2.56
Therefore, one bottle of juice costs $2.56.
3.
Savings spent on personal ornaments = 1/8
Savings spent on clothing = 5/6
Total savings spent = 1/8 + 5/6
= 3/24 + 20/24
= (3+20)/24
= 23/24
Savings left = 1/24 = $130
Total amount of savings = x
As 130 is one part of the total savings,
Total amount of savings =
x = 130 × 24
x = 3120
Therefore, original amount of savings is $3120.
When solving the given equation, what is the first step?
(a)
Given: x - 3=8
А
Add 3 to both sides
B
Subtract 3 from both sides
C
Multiply -3 to both sides
D
Divide -3 from both sides
(b) What is the solution to the give equation?
Given: 1 - 3 = 8
Answer:
A
Step-by-step explanation:
You are given that x - 3 = 8
It's an equation. The first thing you do is add or subtract when you are learning how to handle equations. This is a level 1 equation. That means that the solution is just to add or subtract something.
In this case, x has 3 taken away from it. So you have to get x by itself. The way to do that is to add 3. Then the -3 on the left disappears.
x - 3 + 3 = 8+3
x = 11
The answer is A
Answer:
don't know actually but I can elaborate the solution
Step-by-step explanation:
x-3=8
x=8+3

Answer:
(3)
x = 0
y = 3/7
(4)
x = 6
y = -11
Step-by-step explanation:
the beginning was right, but get mistake was then to add the 2 equations but the parts with the y terms she suddenly subtracted.
no, one operation for everything. and then maybe another operation (and again for everything present).
so, some would multiply by -2 and then truly add.
or, as we will do it now to refuse as much as possible from your friend's work, we multiply by 2 and then SUBTRACT !
5x + 7y = 3
3x + 14y = 6
multiply the first equation by 2 and then subtract the second one.
10x + 14y = 6
- 3x + 14y = 6
-----------------------
7x + 0 = 0
=>
x = 0
then we use this e.g. in the first equation to get y :
5×0 + 7y = 3
7y = 3
y = 3/7
10x + 3y = 27
3x - 5y = 73
let's go e.g. for 15y (multiply the fits by 5 and the second by 3)
50x + 15y = 135
+ 9x - 15y = 219
------------------------
59x + 0. = 354
59x = 354
x = 6
10×6 + 3y = 27
60 + 3y = 27
3y = -33
y = -11

1= a-13/-6
Show your work in details if you can, I have a hard time understanding this.
Answer: 7
Step-by-step explanation:
1. multiply both sides by -6 so the -6 on the right side could cancel out and the left side would be -6: 1= a-13/-6 ==> -6=a-13
2. add both sides by 13 so -13 on the right side could cancel out and the left side would be -6+13: -6=a-13 ==> -6+13=a-13+13
3. you know -6+13 equals 7 right? so the answer is a=7
Hey there! I'm happy to help!
We want to get the a all by itself. For me, I always like to have the variable on the left side, so first, let's just flip this around.
[tex]\frac{a-13}{-6} =1[/tex]
What we want to do is get all of the constants (numbers without variables) on the right side. This will leave a all on its own.
We see that the quantity a-13 is being divided by -6. To undo this, we will just multiply both sides by -6. This will cancel out that -6 and get us closer to having the a isolated.
[tex]\frac{a-13}{-6} *-6=1*-6\\\frac{a-13}{1}=-6\\a-13=-6[/tex]
Now we add 13 to both sides to undo the -13 on the left side.
[tex]a-13+13=-6+13[/tex]
[tex]a+0=7\\a=7[/tex]
