Hello everyone, I have one more question. What is the formula for dividing decimals again? I reviewed this yesterday but continued to forget anyway.
Answers
Answer:
multiply the divisor by as many tens as necessary until we get a whole number, and remember to multiply the dividend by the same number of tens.

Here is trapezoid A in the coordinate plane:
If you drew Trapezoid B, the image of A after a 90\circ∘ rotation clockwise, using the origin as the center of rotation, what would be the coordinates of each of the vertices?
Answers
Answer:
(1,-2) (3,-2) (4,-4) (1,-4)
Step-by-step explanation:
First of all I noted that the origin would be the centre of rotation.
Then I chose a point of Trapezoid A: I selected the point closest to the centre of rotation which was (2,1) , since that is the easiest one to do. However, this works for any point
Then I drew a line from the point (2,1) to the centre of rotation (the origin)
From the origin I then drew another line perpendicular (at a right angle to) the line that I previously drew (between the origin and point (2,1)). I drew this line so that it was also the same length as the previously drawn line and I drew it in the direction of rotation which was clockwise i.e., to the right. This line therefore went from the origin to point (1,-2).
I have now deduced that the point (1,-2) is the same as point (2,1) but in the rotated Trapezoid B.
From there I simply just rotated shape A 90 degrees clockwise so that I knew what the shape would look like if it was rotated.
Then I just drew in the other points to make the rest of the shape.
Sorry if this is hard to understand. I would be able to explain better if I was able to draw this out for you
The required coordinate of the image of the rotation of the trapezoid (1, -2) (3, -2) (4, -4) (1, -4)
Given that,
To determine the coordinate of the given trapezoid after the 90° clockwise rotation with origin as the center of rotation.
The graph is a demonstration of curves which gives the relationship between the x and y-axis.
Here,
Intial coordinates of the trapezoid, (1,2) , (3, 2), (4, 4) and (4, 1)
After the rotation of 90° clockwise, the trapezoid is translated to the 4 quadrants and the new coordinates are (1, -2) (3, -2) (4, -4) (1, -4).
Thus, the final coordinates are, (1, -2) (3, -2) (4, -4) (1, -4).

The cost at a store for a package of pens is $3 and for a three-ring binder
is $4. Write a variable expression for the cost of buying p packages of
pens and b binders. How much would 3 packages of pens and 8 binders
cost?
Answers
Hey there! I'm happy to help!
Our question tells us that the number of packages is p and that the number of binders is b.
Each package is $3, so for every p we have, we will have 3 more dollars. So we have 3×p, which is written as 3p.
The same goes for binders. For every binder, we have 4 more dollars, so we have 4×b which is just written as 4b.
An expression is just a number sentence without an equal sign, so something like 1+1 or 7x². The variables are just the letters or symbols that represent an unknown quantity (so 7x² is a variable expression).
Our total cost is going to be the cost of our packages and our binders, so we combine the 3p and 4b we previously came up with, so our expression is 3p+4b.
Now, we can plug in our amounts of each thing into the equation. We will insert our 3 packages in plae of the p and our 8 binders in place of the b to find our cost.
In algebra, you can also write multiplication as a number outside of a number in parentheses so 4(2)=8 for example.
3(3)+4(8)
9+32
41
So, the total cost is $41.

Answers
Answer:
20%
Step-by-step explanation:
Step 1: Start by changing the fraction to a decimal by diving the numerator by the denominator (1 divided by 5). That equals 0.2.
Step 2: Change the decimal to a percent by multiplying it by 100%, or moving the decimal two places. That gives you 20%.
Another way of thinking about it is multiplying the numerator by 100%, then dividing that by the denominator (100% divided by 5). This gives you 20%.
Answer: 20%

3/2 - 5d = -1/2
calculate the difference
-5d = -2
divide both sides by -5

You can easily solve this equation by doing factoring (a fancy word for dividing)
so, factor out the Greatest Common Factor (GCF)
which is
B^5
so in parenthesis write (1+b^3) next to it, think of subtracting the two exponents, and then since theres only 1 thing left after factoring out b^5, you leave a 1 behind.
b^5(1+b^3)
from here, in the parenthesis, you have 2 perfect cubes, 1 and b^3
take the cube root of that which is (1+b)
then use (a+b) which is already done
AND (a^2-ab+b^2) where a is equal to 1, and b is equal to variable b.
so, that would be
x^5(1+x)(1-1x+x^2) ( this is what you should get once you do multiply the square root out to just get constants and coefficients.
That gives us our final answer of x^5(1+x)(1-1x+x^2) because it is in the simplest form possible.

Subtract 1 from both sides.
3(x-5)=1+x
Distribute the 3
3x-15=1+x
Add 15 to both sides.
3x=16+x
Subtract x from both sides.
2x=16
Divide both sides by 2.
x=8

The subtraction problem 11.5−7.2 can be rewritten as the addition problem _[blank]_.
Answers
The subtraction expression 11.5−7.2 in the form of addition will be 11.5 + 7.2.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression of subtraction is,
E = 11.5−7.2
The expression in the form of addition will be converted by changing the sign of 7.2.
E= 11.5 - (-7.2)
E = 11.5 + 7.2
Therefore, the subtraction expression 11.5−7.2 in the form of addition will be 11.5 + 7.2.
