when you are adding with decimals, where do you put the decimal?
Answer: hope this helps
Step-by-step explanation:
Write down the numbers, one under the other, with the decimal points lined up.
Put in zeros so the numbers have the same length (see below for why that is OK)
Then add, using column addition, remembering to put the decimal point in the answer.

Answer:
1.) 471.24
2.) 1231.5
3.) 113.1
Step-by-step explanation: A = pi x r^2 + pi x r x ^2
1.) a = 3.14 x (5)^2 + 3.14 x 5 x ^2
a = 3.14 x 25 + 3.14 x 5 x 25
a = 78.54 + 392.70
a ≈ 471.24
2.) A = 3.14 (7)^2 + 3.14 x (7) x ^2
a = 3.14 x 49 + 3.14 x 7 x 49
a = 153.93 + 1077.57
a ≈ 1231.5
3.) a = 3.14 (3)^2 + 3.14 x 3 x ^2
a = 3.14 x 9 + 3.14 x 3 x 9
a = 28.27 + 84.82
a ≈ 113.1

Calculate the Area of the square
Answer: 80 cm ^2
Step-by-step explanation:
Largest square = 11 by 11
Smallest square = 8 by 8
Side of triangle =
a^2 + b^2 = c^2
you can only use this formula for right angled triangles. it's called the pythagorean theory
in this case you are looking for a^2
a^2 + 8^2 = 11^2
a^2 + 64 = 144
a^2 = 144 - 64
a^2 = 80
in this case. the number isn't going to be friendly.
a = 8.9443
a is just that one side of that triangle though.
but in the end
Area of medium square = 80
because
8.9443 x 8.9443 = 80

What is the difference between a linear solid line and a set of unconnected points? I don't understand. (Giving 15 points!)
Answer:
A connected, solid, graph is called a continuous graph. A disconnected graph, made of separate dots, is called a discrete graph.
Step-by-step explanation:
A discrete graph shows us that there are no data values between the whole numbers on which the points are plotted. This generally means no decimal portions. However, when representing time, we can have a decimal portion of a year; this means the graph would have values between the whole numbers and would be continuous, or solid.

A farmer's land is separated into sections of size 3 3/4 acres. Suppose there are 2 1/5 such sections. How many acres of land does the farmer own?
Write your answer as a mixed number in simplest form.
Answer:
This is simple multiplication of fractions, not too bad!
we have 2 7/9 sections of farmland, each 2 1/5 acres large. To find the total acreage, multiply 2 1/5 by 2 7/9. The first step here is to convert to improper fractions.
To convert to improper fractions, multiply the denominator of the mixed number by the "whole number" portion of it. Then, add the numerator of the mixed number. For example, for 2 1/5, I would multiply 5 * 2 to get 10, then add 1 to get 11. Then, I keep the original denominator, so 11/5.
Let's do the same for 2 7/9. 9 * 2 = 18, then add 7 to get 25. The improper fraction is 25/9.
Now, we multiply the two fractions. This is just multiplying both numerators and both denominators, straight across.
(11*25)/(9*5) = 275/45 => 55/9, so that's the total acreage, or in decimal form, about 6.11 acres.
Jada’s dog was 5 1/2 inches tall when it was a puppy. Now her dog is 14 1/2 inches taller than that. How tall is Jada’s dog now?
Answer:
20 inches tall
Step-by-step explanation:
To find the dog's current height, add 14.5 to 5.5
5.5 + 14.5
= 20
So, Jada's dog is now 20 inches tall

⦁ Let x = 4.7 and solve both inequalities below. Show your work.
A: × + 6.2 ≥10.9 B: x - 6.2 ≤ - 5
⦁ Look at your answers to question #4. Which inequality is true or false given x = 4.7. Explain your answer.
Answer:
A is true and B is false.
Step-by-step explanation:
x + 6.2 ≥ 10.9
Replace x for 4.7...
4.7 + 6.2 ≥ 10.9
10. ≥ 10.9 ( So this is true!)
x - 6.2 ≤ - 5
Replace x for 4.7...
4.7 - 6.2 ≤ -5
-1.2 is not ≤ -5 (So this is false!)
How is solving a two-step equation similar to solving a one-step equation?
Answer:
Because it is the same concept, now u have to do more work.
For example
1+1 would be a one step equation
and
1+1(5) would be a two step equation
it's just a bit more.
Each step in solving an equation is like solving a one-step equation so solving a two-step equation is similar to solving a one-step equation
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 9 is an equation
We have,
Two steps equation.
Example:
2 + 3 - (3 x 4)
Step 1:
2 + 3 - 12
Step 2:
5 - 12
-7
One-step equation.
Example:
2 + 4
Step 1:
2 + 4
6
We see that,
Solving a two-step equation is similar to solving a one-step equation because, in the two-step equation, each of the two steps is like one step individually.
Thus,
Solving a two-step equation is similar to solving a one-step equation.

Martha has two jobs. One pays $15 per hour, and she works at that job 10 hours per week. The other job pays $13 per hour, and she works at that job 30 hours per week. How much money does she make per year?
Answer:
28,080$
Step-by-step explanation:
One year - 52 weeks.
First job - 15$/h - 10h/w => Income = 15$/h * 10h/w * 52w = 7800$
Second job - 13$/h - 30 h/w => Income = 13$/h * 30h/w * 52w = 20 280$
Total income 7800$ + 20,280$ = 28 080$

Reflect (2.5,4.5) in the x-axis.
What is the equation of the graph obtained by reflecting y=3^x In the x axis
Answer:
y=-3x
Step-by-step explanation:
Shows the original equation reflected arcoss x axis
The equation of the graph obtained by reflecting y = 3ˣ in the x-axis is y = -3ˣ .
To reflect a function in the x-axis, we change the sign of the y-values of each point on the graph. In this case, we are reflecting the function y = 3ˣ .
When we reflect y = 3ˣ in the x-axis, the equation becomes y = -3ˣ. The negative sign in front of the 3ˣ term indicates the reflection in the x-axis .
Therefore, the equation of the graph obtained by reflecting y = 3ˣ in the x-axis is y = -3ˣ .
