What did my teacher do to get the answer to this question?
Step-by-step explanation:
since perimeter is adding all around she took the all the values and added them as above. as you can see 3√2 and 4√2 has the same square root so she added 3+4 which gave us 7√2 and then added the 2√5 but since they don't have the same square root we can't add them like we did in the other so we'll just put 7√2+2√5

15 units
O
20 units
R
Х
Q
0
24 units
Answer:
C. 20 units
Step-by-step explanation:
x > 16 because the hypotenuse is always the longest side
9 + 16 = 25
25 > x
that leaves you with 20 units and 24 units but 24 units is too long, so C. 20 units is the answer
Tthe value of x is 20 u
To get the value of x from the diagram, we will use the triangle altitude theorem as shown below;
From the diagram;
9/RT = RT/16
RT^2 = 9*16
RT^2= 144
RT = 12
Get the value of x using the pythagoras theorm;
x^2 = 16^2 + 12^2
x^2 = 256 + 144
x^2 = 400
x = 20
Hence the value of x is 20 units

what conjecture can you make about the sum of firs 52 positive even numbers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. However, the available details is enough to work out a solution.
Considering the first even number: 2
In this case, n = 1
The sum of the first even term is 2.
Represent the sum as a product:
[tex]2 = 1 * 2[/tex]
Considering the first two even numbers: 2 and 4
In this case, n = 2
The sum of the first two even terms is 6
Represent the sum as a product:
[tex]6 = 2 * 3[/tex]
Considering the first three even numbers: 2, 4 and 6
In this case, n = 3
The sum of the first two even terms is 12
Represent the sum as a product:
[tex]12 = 3 * 4[/tex]
Notice the pattern from n = 1 to 3
[tex]2 = 1 * 2[/tex] --- n = 1
[tex]6 = 2 * 3[/tex] --- n = 2
[tex]12 = 3 * 4[/tex] --- n = 3
------------------------------------
It follows that, the sum when represented as a product is: [tex]n * (n + 1)[/tex]
So, the sum of the first 52 even terms would be:
[tex]52 * (52 + 1)[/tex]
Where n = 52
[tex]52 * (52 + 1) = 52 * 53[/tex]
[tex]52 * (52 + 1) = 2756[/tex]
Hence, the sum of the first 52 even terms is 52 * 53 or 2756

Brendan worked 7 11/12 hours on Saturday, on Sunday he worked 84% of the hours he worked on Saturday. How many total hours do he work last weekend?
Answer:
[tex]14\frac{17}{30}[/tex]hrs
Step-by-step explanation:
Given parameters:
Time worked on Saturday = [tex]7\frac{11}{12}[/tex]
Unknown:
Total hours he worked last weekend = ?
Solution:
Since Brendan worked 84% of the time he worked on Saturday on Sunday;
Time worked on Sunday = [tex]\frac{84}{100}[/tex] x [tex]\frac{95}{12}[/tex] = [tex]\frac{133}{20}[/tex]
Total time worked last weekend = Time worked on Saturday + Time worked on Sunday;
Total time worked = [tex]\frac{95}{12}[/tex] + [tex]\frac{133}{20}[/tex]
Total time worked = [tex]\frac{475 + 399}{60}[/tex]
Total time worked = [tex]\frac{874}{60}[/tex]
Total time worked = [tex]\frac{437}{30}[/tex] = [tex]14\frac{17}{30}[/tex]hrs

So, perimeter = 35x+18
Option F is correct.
2. Square Perimeter
Side of square = 4x-8
The formula used is:[tex]Perimeter=4a[/tex]
where a is side of square
Putting values in formula
[tex]Perimeter=4a\\Perimeter=4(4x-8)\\Perimeter=16x-32[/tex]
So, perimeter of square = 16x-32
Option C is correct.
3. Pentagons perimeter
Side of pentagon= 2x-4

When a decimal is written in word form, what indicates whether the number can be written as a mixed number or as a fraction less than 1
9514 1404 393
Answer:
"and"
Step-by-step explanation:
Properly written, the word "and" separates the integer portion from the fractional portion of the number. If there is no "and", then there is no integer portion, so the number is a fraction less than 1.

David is having a cookout. Hot dogs and buns are sold based on the following quantities per package.
Item
Amount Per Package
Hot dog buns
12
Hot dogs
10
A
David thought that he would have to buy 12 packages of hot dog buns and 10 packages of hot dogs to have one bun for each hot dog.
What is the LEAST amount of each David would need to buy to have an equal number of hot dogs and buns?
David should buy 2 packages of buns and 2 packages of hot dogs,
David should buy 6 packages of buns and 5 packages of hot dogs.
с David should buy 5 packages of buns and 6 packages of hot dogs,
D David should buy 22 packages of buns and 22 packages of hot dogs
B
Answer: Choice C) David should buy 5 packages of buns and 6 packages of hot dogs.
========================================================
Explanation:
Focus on the hot dog buns for now
1 package = 12 hot dog buns
2 packages = 24 hot dog buns (multiply both sides by 2)
3 packages = 36 hot dog buns (multiply original equation by 3)
We can see that the multiples of 12 are being listed. So we have
12, 24, 36, 48, 60, 72, 84, ...
as the possible number of hot dog buns we could get if we buy 1,2,3... packages.
The possible number of hot dogs we can get are
10, 20, 30, 40, 50, 60, 70, 80, ...
which are multiples of 10. Simply add 10 to each item to get the next one.
--------------------------------
Considering these two sets
12, 24, 36, 48, 60, 72, 84, ...
10, 20, 30, 40, 50, 60, 70, 80, ...
what is the lowest common multiple? That would be 60 since it is found in both lists and it is the smallest in common.
The LCM of 12 and 10 is 60.
If he wanted 60 hot dog buns, then 60/12 = 5 packages of buns is what he needs.
If he wanted 60 hot dogs, then he needs 60/10 = 6 packages of hot dogs.
Therefore, David should buy 5 packages of buns and 6 packages of hot dogs. The answer is choice C.
--------------------------------
Side note: a different way to find the LCM is to multiply 10 and 12 to get 10*12 = 120. Then we divide by the GCF 2 getting 120/2 = 60.

1. Tia cut a 4-meter 8-centimeter wire into 10 equal pieces. Marta cut a 540-centimeter wire into 9 equal pieces. How much longer is one of Marta’s wires than one of Tia’s?
2. Jay needs 19 quarts more paint for the outside of his barn than for the inside. If he uses 107 quarts in all, how many gallons of paint will be used to paint the inside of the barn?
3. String A is 35 centimeters long. String B is 5 times as long as String A. Both are necessary to create a decorative bottle. Find the total length of string needed for 17 identical decorative bottles. Express your answer in meters.
Answer:
Tia cut a 4-meter 8-centimeter wire into 10 equal pieces. for Jay 10 quarts would be the answer. Step-by-step explanation: He needs x quarts for the inside painting and x + 19 quarts for the outside. These two measures add up to 2x + 19, which equals 107 (quarts) total. The last one is tring A is 35 cm long, string B is 5 times as long as string A, then string B is 35·5=175 cm long. In total both strings have length 35+175=210 cm. The total length of string needed for 17 identical decirative bottes is cm that is 35.7 m.

Haleigh split 4/9 of a gallon of juice into 8 cups. How much juice was in each cup?
━━━━━━━☆☆━━━━━━━
▹ Answer
1/18 of a gallon of juice in each cup.
▹ Step-by-Step Explanation
Since we have 4/9 of a gallon of juice for 8 cups, we will divide to find the amount of juice in each cup.
[tex]\frac{4}{9} / 8[/tex]
Since this operation is division, we have to change 8 to it's reciprocal which is 1/8:
[tex]\frac{4}{9}/ \frac{1}{8} = \frac{4}{72} = \frac{1}{18}[/tex]
Our final answer will be 1/18 of a gallon of juice in each cup.
Hope this helps!
