Answer:
1936
Step-by-step explanation:
The sum of the first n odd numbers is n^2
This can be proven, but for 5 odd numbers, 1,3,5,7,9, the sum should be 5^2, or 25, which it is
So for the first 44 odd numbers, the sum is n^2=44^2=1936
Solve for x
3x - 2 (x - 4) = 5 (2x + 1 )
Answer:
yes
Step-by-step explanation:
Answer:
3x–2x+8 = 10x+5
=> x + 8 = 10x + 5
=> 8 – 5 = 10x – x
=> 9x = 3
=> x = 3/9
=> x = 1/3

4y + 3x = 5 solve for x
Answer:
Move all terms that don't contain x to the right side and solve.
x = 5 /3 − 4 y /3
Answer:4y+3x=5
Step 1: Add -4y to both sides.
3x+4y+−4y=5+−4y
3x=−4y+5
Step 2: Divide both sides by 3.

Juan's class is going to construct an outdoor garden. The garden will be in the shape of a square, Juan's teacher gave the class three
options for the area of the garden: 30 square feet, 40 square feet, or 50 square feet.
Part A
Without using a calculator, approximate the side length, to the nearest tenth of a foot, for the garden with an area of 30 square fet. Show
your work.
Part B
The other two garden options have approximate side lengths of 6.3 feet and 7.1 feet. Locate and graph the three points on a horizontal
number line to show the approximation of the side length for each option.
Answer:
Part A: 5.5
Part B: Kindly refer to the attached image for the number line representation.
Step-by-step explanation:
Given that:
Possible area of the first garden = 30 sq ft
Possible area of the second garden = 40 sq ft
Possible length of the second garden = 6.3 ft
Possible area of the third garden = 50 sq ft
Possible length of the third garden = 7.1 ft
To find:
Part A: Side length of the square with area 30 sq ft to the nearest tenth.
Part B: Locating and graphing the three points on a horizontal number line.
Solution:
Formula for area of a square:
[tex]Area =(Side)^2[/tex]
Part A: Given that area = 30 sq ft
Putting in the formula to find the value:
[tex]30=Side^2\\\Rightarrow Side = 5.477 \approx \bold{5.5\ ft}[/tex]
Part B:
Kindly refer to the attached image for the number line representation of the given two lengths and the length calculated for the first square.
The three lengths are 5.5, 6.3 and 7.1 respectively.
The three numbers to located on the graph are = 5.5, 6.3 and 7.1
pearl will put wire around a rectangular lot with a width of 20m and a length that is two times its width.how many mters of wire will she need?
Answer: 120m
Step-by-step explanation:
Width = 20m
Length = 2 × width
= 2 × 20m
= 40m
We've to calculate the perimeter
Perimeter = 2(length + Breadth)
= 2(20m + 40m)
= 2(60m)
= 120m

Anita to make the same amount of money?
A. 1.75
B. 121
C. 7
D. 30.25
Answer:
the answer is c
Step-by-step explanation:
hope this helpss!!
Answer:
7
Step-by-step explanation:
57000+2500x=64000+1500x
subtract 1500x from both sides
57000+1000x=64000
subtract 57000 from both sides
1000x=7000
divide both sides by 1000

What is the equation of the line that passes through the point (-2,-2) and has a
slope of 4?
Answer:
y=4x+6
Step-by-step explanation:
To find the equation of a line, use y=mx+b form. In this case, we need to find b and then find known values. When the line passes through the point (-2, -2) and has a slope of 4, we use the form to find the equation, and we will get y=4x+6.

Dante is making a necklace with 18 rows of tiny beads in which the number of beads per row is given by the series 2 + 8 + 14 + 20 + ...
a. Use sigma notation to write the series. Explain what the numbers in the sigma notation represent in this situation and how you found the expression used in the summation.
b. Find the total number of beads in the necklace. Explain your method for finding the total number of beads.
Answer:
Step-by-step explanation:
Well, first we are going to add the beads together.
2 + 8 + 14 + 20 = 44
Next, let's multiply the sum by 18 because there are 18 rows of 44 beads.
18 x 44 = 792
I hope this answer helps. I not sure how to solve the sigma notation part, but there is the solving part. ;)
Sam can make 15 pizzas in two and a half hours. At this rate, how many pizzas can Sam make in 8 hours
Answer:
Sam can make 48 pizzas.
Step-by-step explanation:
Sam is making three pizzas every thirty minutes. Since eight hours is equivalent to 16 sets of 30 minutes, you have to multiply 3x16, which equals 48.

Function g is defined as g(x)=kf(x). What is the value of k?
Pick an x value like x = 2
Note that f(2) = 1 and g(2) = 2. This shows we've doubled the f(x) value to get g(x). Therefore k = 2.
Or you could pick on x = 4 to see f(4) = 2 and g(4) = 4. The output of f(x) has been doubled as well.
It doesn't matter what x is since we'll have this doubling effect go on. I recommend picking x values where the points on the blue graph land perfectly on a grid location. Something like x = 5 seems a bit tricky.
Answer:
K = 2

A student saves money to buy a laptop. The student already has 307.50 saved and puts aside $100 each month to help pay for the laptop. After 5 months, the total amount saved is 75% of the total cost of the laptop. How much more does the student need to save to buy the laptop rounded to the nearest cent.
Answer:
The amount the student needs to save is approximately $269.167
Step-by-step explanation:
The amount the student already has saved for his laptop = $307.50
The amount the student puts aside each month to pay for the laptop = $100
The total amount saved after 5 months = 75% of the total cost of the laptop
Therefore, we have;
The total amount the student has after 5 months = $307.5 + 5 × $100 = $807.5
The total amount saved after 5 months = 75% of the total cost of the laptop
Therefore;
$807.5 = 75% of the total cost of the laptop
The total cost of the laptop = $807.5/75% = $807.5/75 × 100 = [tex]\$ \ 1076\frac{2}{3}[/tex]
The total cost of the laptop ≈ $1076.67
Therefore;
The amount the student needs to save = $1076.67 - $807.5 = [tex]\$ \ 269\frac{1}{6}[/tex]
The amount the student needs to save ≈ $269.167.
(4) Abdi has two electric train sets: A and B. Each train is on its own circular track. He starts both trains at the same time. Train A returns to its starting point every 12 seconds. Train B returns to its starting point every 9 seconds. If the trains continue traveling, what is the least amount of time, in seconds, that both trains will arrive at the starting points at the same time?
Answer:
The least amount of time both trains will arrive at the starting points at the same time is 36 seconds.
Step-by-step explanation:
From the question, Train A returns to its starting point every 12 seconds and Train B returns to its starting point every 9 seconds.
First, we will determine the times the trains will return to the their starting points.
For Train A,
The second time Train A will return to its starting point will be at 24 seconds,
The third time will be at 36 seconds
The fourth time will be at 48 seconds and so on.
For Train B,
The second time Train B will return to its starting point will be at 18 seconds,
The third time will be at 27 seconds
The forth time will be at 36 seconds and so on.
Since both trains arrive at their starting points at 36 seconds,
Hence, the least amount of time both trains will arrive at the starting points at the same time is 36 seconds.

Which numbers are between the numbers represented by Points A and B on the number line? Check all that apply. A number line going from negative 1 to 0. Point A is at negative 0.8. Point B is at negative 0.2. Negative StartFraction 7 Over 10 EndFraction Negative StartFraction 9 Over 10 EndFraction Negative one-half Negative one-fourth Negative two-fifths
Answer:
a,c,d,e
Step-by-step explanation:
The points A = -0.8, B = -0.2, C = -0.7, D = -0.9, E = -0.5, F = -0.25, and G = -0.4 lie between -1 and 0 on the number line.
What is the number?An arithmetic value used to indicate an amount is called a number. A number is a mathematical concept that is used for counting, measuring, and labeling. Thus, mathematics is built on numbers.
Given:
A number line going from negative 1 to 0,
the number Point A = -0.8, B = -0.2, C = -7 / 10, D = -9 / 10, E = -1 / 2, F = -1 / 4, and G = -2 / 5
Convert all the points in decimal form as shown below,
C = -7 / 10 = -0.7
D = -9 / 10 = -0.9
E = -1 / 2 = -0.5
F = -1 / 4 = -0.25
G = -2 / 5 = -0.4
As you can see that the numbers lying between -1 and 0,
Thus, all points lie on the number line between -1 and 0.
