Answer:Let's start with the underlying fact. Multiplication simply is not repeated addition, and telling young pupils it is inevitably leads to problems when they subsequently learn that it is not. Multiplication of natural numbers certainly gives the same result as repeated addition, but that does not make it the same.

The diameter of a circle is 3 ft. Find its area to the nearest tenth.
PLS FOLLOW THE RULES
TROLL FOR POINTS= REPORT
FIRST AND CORRECT ANSWER= BRAINLIEST
( NO LINKS )
Answer:
7.1 (7.06 rounded to the tenth)
Step-by-step explanation:
The formula for Area of a Circle is: π·r²
R = Radius
π = pi, or 3.14
As long as you know the formula, this is easy!
In class, you may have already been told that the radius is half of the diameter.
1. Half of 3 ft is 1.5 ft.
2. Plug 1.5 in for r, in your calculator
3. Do the calculation, and you should come out to get 7.06858347058
4. Round it!
Finding area for a circle is satisfying, isn't it? xD

Emma types one-third of a paper for History class in 34 hour. What part of the paper can she type in one hour?
Answer:
What part of the paper can she type in one hour. The hours cancel out, leaving us with: 1/3 x 4/3 paper/hour Multiplying the numerators and denominators, we get: 4/9 paper/hour So Emma can type 4/9 of a paper in one hour.

A rectangular city lot has an area of 1,000 square meters. If the length of the lot is 10 meters more than twice its width, find the length and width. Write the quadratic equation.
Answer:
Length of the Area = 50mtrs
Width of the Area = 20mtrs
Step-by-step explanation: Let the x be the length and y be the width of the Area. So we can write x = 2 y + 10 and x y = 1000 or ( 2 y + 10 ) y = 1000 or 2 y 2 + 10 y = 1000 or 2 y 2 + 10 y − 1000 = 0 or y 2 + 5 y − 500 = 0 or y 2 + 25 y − 20 y − 500 = 0 or y ( y + 25 ) − 20 ( y + 25 ) = 0 or ( y + 25 ) ( y − 20 ) = 0 or y + 25 = 0 or y − 20 = 0 or y = − 25 Invalid value contains negative sign or y = 20 So Width of the Area is 20 ----------Ans By plugging the value of y = 20 in the eqn x = 2 y + 10 we get Length of the Area = 2 × 20 + 10 = 50 -------------Ans
The ratio of the number of Aaliyah’s pens to the number of Mariah’s pens was 2:3 at first. After Dad gave Aaliyah another 16 pens, the ratio became 2:1.
a) How many pens did Mariah have?
b) If Mariah gave away 6 pens, what would be the new ratio of the number Aaliyah’s pens (after Dad gave her 16 pens) to the number of Mariah’s pens?
y'all better help me with this one
Answer:
(2x + 16)/3x = 2/1
2x + 16 = 6x
4x = 16
x = 4
Aaliyah's pens = 2x = 2 × 4 = 8
the number of Maria's pen = 3x = 3 × 4 = 12 -----Part A
New ratio = (8 + 16)/6
24/6 = 4/1 = 4 : 1 --------- Part B Step-by-step explanation:

If you fold a number line so that a vertical crease goes through 0, the points you label would match up. Explain why this happens.
It would happen because 5 is 5 4 is 4 3 is 3 2 is 2 1 is 1 and 0 is only one number 0.
If we fold a number line so that a vertical crease goes through 0, the points will match up for the same because of the same distance on both sides from zero.
What is a number line?A number line is a straight line representing numbers on it either vertically or horizontally.
If we fold a number line so that a vertical crease goes through 0, the points will match up for the same. this is due to the reason the points on a number line from zero are at the same distance on both sides so, the numbers will superimpose on each other when folded vertical through 0.
Since the distance of 1 and -1 is the same as zero so 1 would match -1.
Similarly for -2 and 2, -3 and 3, etc.

Solve this equation until you have the squared variable for the missing side length on one side of the equal sign and a rational number on the other.
The solution of the equation 9² + 12² = c² will be 15 and negative 15.
What is the solution to the equation?A designation of amounts to the unknown parameters that establish the equals in the formula is referred to as a result.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The equation is given below.
9² + 12² = c²
Simplify the equation, then the value of the variable c will be
c² = 81 + 144
c² = 225
c = ±√225
c = ±√(15)²
c = ± 15
Thus, the solution of the equation 9² + 12² = c² will be 15 and negative 15.

Answer:
Step-by-step explanation: Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
