Find the sum of integers from 33 to 47:
Answer:
Step-by-step explanation:There are formulas to work this out, but you can also suss out an answer by a liberal application of critical thinking.
Okay, you want to add 51 + 52 + 53 + … + 99 + 100, right? (The … represents all the numbers in between, in case you were wondering.)
Well, that’s a total of 50 numbers. And if you know anything about addition, you know that it doesn’t matter what order you add them.
So you could also say 51 + 100 + 52 + 99 + 53 + 98 + … and so on.
Let’s see what happens. 51 + 100 = 151. So far so good.
Then, 52 + 99 also equals 151. And 53 + 98 also equals 151. Since there are 50 numbers, that’s 25 pairs that are going to add up to 151.
151 + 151 + 151 + 151 + … (21 more instances of 151).
So we can simplify our workload a bit. Instead of adding up all the numbers by hand, we can just multiply 151 by 25.
151 x 25 = 3775
From that, we can work out a generic formula that will allow you to add any sequence of numbers…without actually adding.
Let a be the first number in the sequence, and let n be the last number in the sequence. The number of numbers is (n - a) + 1. (You have to add 1, because if you just subtract, it’s like you’re losing the lowest number in the sequence).
So…you get the sum by adding the first and last number in the sequence, and then multiplying that result by half of the total number of numbers.
(a+n)((n−a)+12)
an−a2+a+n2−an+n2
−a2+a+n2+n2
−a(a−1)+n(n+1)2
Let’s check to see if it works!
−51(51–1)+100(100+1)2
−51(50)+100(101)2
−2550+10,1002
75502
3775
Note that if the starting number were 1, the formula would simplify to n(n+1)2
Following are the calculation to the sum of integers:
Given:
33 to 47
To find:
Sum of integers=?
Solution:
Given numbers:
33 to 47
[tex]\to \bold{33,34,35,36,37,38,39,40,41,42,43,44,45,46,47}[/tex]
Using formula:
[tex]\bold{S = \frac{n(a + l)}{2}}[/tex]
[tex]n=15\\\\a=33\\\\l=47 \\\\ \bold{S = \frac{15(33 + 47)}{2}}\\\\[/tex]
[tex]\bold{= \frac{15(80)}{2}}\\\\\bold{= \frac{1200}{2}}\\\\\bold{= 600}[/tex]
Therefore, the sum of the integers "600".

Consider a square and a regular hexagon (a six sided figure with sides of equal length). One side of the square is 8 feet longer than a side of the hexagon, and the two figures have the same perimeter. What are the lengths of the sides of each figure?
Answer:
The hexagon has sides of 8 feet and the square 's sides are 16 feet long..
Step-by-step explanation:
If the side of the hexagon is x feet then the side of the square = x+8 feet.
So as the perimeters are equal:
8x = 4(x + 8)
8x = 4x + 32
8x - 4x = 32
4x = 32
x = 8 = side of hexagon so the square side = 16 feet.

A sandwich is 2 12 feet long. You decide to cut the sandwich into pieces that are 1 14 feet long. How many pieces will you cut?
Answer:
Im assuming you meant 2 1/2 and 1 1/4, so the answer would be 2 pieces
Step-by-step explanation:
2 1/2-1 1/4=1 1/4, so 2
Using the division operation, the number of pieces of sandwich that can be cut is 2
Given the Parameters :
Length of sandwich = 2.5 feets Length per piece cut = 1.25 feetsThe number of pieces that can be cut out of the sandwich can be calculated thus :
Length of sandwich ÷ Length per piece cutNumber of pieces = (2.5 ÷ 1.25) = 2
Therefore, there are 2 pieces of sandwich that can be cut.

Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise. How much will she earn each hour after the raise?
Answer:
28.75
Step-by-step explanation:
We can do 15% of 25 which is 3.75. Add this on to 25, and get 28.75.
The amount she is earning each hour after the raise is $28.75 if Sanya currently earns $25.00 an hour at her job.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise.
The raise = 15 % of 25 = 3.75
Total after raise = 25.00 + 3.75 = $28.7
Thus, the amount she is earning each hour after the raise is $28.75 if Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise.

In the diagram, m || n. Find the value of x. Explain how you obtained your answer.
Answer:
x = 67°
Step-by-step explanation:
It's given that m║n.
Construction done: A line 't' parallel to the given lines 'm' and 'n'.
Since, m║t and a transversal line is intersecting these lines.
m∠a = 35° [Alternate interior angles]
m∠c = 180° - 148° [∠c and angle measuring 148° are the linear pair of angles]
= 32°
n║t and a transversal line is intersecting these lines.
Since, ∠b ≅ ∠c [Alternate interior angles]
m∠a + m∠b = m∠x [Angle addition postulate]
x = 32° + 35°
x = 67°
Therefore, measure of angle x is 67°.

What is the value of the x-intercept?
What is the value of the y-intercept?
Remember when finding the x-intercept you cover up the y (put 0 in for y) and solve for the x value.
Answer:
see below
Step-by-step explanation:
−x+y=−5
To find the x intercept, let y=0 and solve for x
-x +0 = -5
-x = -5
x=5
The x intercept is 5
To find the y intercept, let x=0 and solve for y
0 +y = -5
y = -5
The y intercept is -5

lin makes sparkling orange juice by mixing 3 liters of orange juice with 4 liters of soda water. Noah makes sparkling orange juice by mixing 4 liters of orange juice with 5 liters of soda water. How do the two mixtures compare in taste explain your reasoning
Answer:
Step-by-step explanation:
Lin makes sparkling OJ using the ratio
3:4. Meaning 3L orange juice for every 4L sparkling water.
Noah makes sparkling OJ using the ratio 4:5. Meaning 4L orange juice for 5L sparkling water.
If we said that they both used 12L of orange juice,
Lin would have to use 16L of sparkling water
Noah would have to use 15L of sparkling water
So for the same 12L of orange juice, Lin uses more sparkling water.
Therefore her sparkling OJ would be more diluted (less orange flavour since you added more water) and more bubbly than Noah's.
