15. Explain how you can calculate each square
root mentally.
a) 31 x 31
b) 431 X 431
c) 17 squared
d) 432 squared
Final answer:
Mentally calculating square roots for perfect squares like 31 x 31 or 17 squared is identifying the number that was squared, for instance, 31 or 17 respectively. Larger numbers may require a calculator.
Explanation:
The question is asking how to mentally calculate the square roots of certain numbers. For perfect squares, such as 31 x 31 or 17 squared (which is 17 x 17), the process is straightforward because the square root of a perfect square is the number that was squared.
For instance, the square root of 31 x 31 is 31, and the square root of 17 squared is 17. However, for large numbers like 431 x 431 or 432 squared, while they are also perfect squares, mental calculation might be impractical due to their magnitude, and a calculator would typically be used.

nalia worked 3.5 hours more than lisa together they worked a total of 18 hours lisa worked h hours
Answer:
7.25 and 10.75 Hours
Step-by-step explanation:
Total hours Nalia and Lisa worked = 18 Hours
Nalia worked 3.5 hours then Lisa which is [tex]h[/tex] hours
⇒[tex]h + (h + 3.5) = 18[/tex]
[tex]2h + 3.5 = 18\\2h = 18 - 3.5\\2h = 14.5\\h = \frac{14.5}{2} \\h = 7.25[/tex]
Lisa has worked for 7.25 hours
Nalia has worked for = 7.25 + 3.5 = 10.75 hours
What decimal is equal 35%
Answer: 0.35
Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100. We can think of 35% as the ratio 35 to 100 or 35 ÷ 100. Remember that dividing by 100 moves the decimal point 2 places to the left. Therefore, 82 ÷ 100 would move the decimal point 2 places to the left which would give us .35 or 0.35.
35% can be written as the decimal 0.35.
The decimal equivalent of 35% is 0.35 .
Given,
35%
Now,
To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100. We can think of 35% as the ratio 35 to 100 or 35 ÷ 100. Remember that dividing by 100 moves the decimal point 2 places to the left.
Therefore, 35 ÷ 100 would move the decimal point 2 places to the left which would give us .35 or 0.35.
Hence,
35% can be written as the decimal 0.35.

Sarah is making strings of beads in the first string she uses 3 beads and she triples the number of beads in each of the next strings identify the number of beads she uses in 5th string.
Answer:
She uses 243 beads for the 5th string.
Step-by-step explanation:
In this problem, we can see a pattern. If she triples the number of beads in each of the next strings, that means that we just take the last number and multiply by 3. If the first string uses 3, then:
The second uses 9, 3 * 3 = 9
The third uses 27, 9 * 3 = 27
The fourth uses 81, 27 * 3 = 81
And the 5th uses 243, 81 * 3 = 243.
The great factory makes 6,793 toys each day. It makes 257 more toys than the super toy factory. How many toys does the super toy factory make each day?
Final answer:
The super toy factory makes 6,536 toys each day, which is calculated by subtracting the 257 additional toys made by the great factory from its total production of 6,793 toys.
Explanation:
To determine how many toys the super toy factory makes each day, we need to subtract the number of additional toys made by the great factory from its total daily production. The great factory makes 6,793 toys each day and it makes 257 more toys than the super toy factory. So:
Number of toys made by the super toy factory = Number of toys made by the great factory - Extra toys made by the great factory
Number of toys made by the super toy factory = 6,793 - 257
After performing the subtraction:
Number of toys made by the super toy factory = 6,536
Therefore, the super toy factory makes 6,536 toys each day.

A box contains 24 oranges. Mr. Lee ordered 8 boxes for his store and 12 boxes for his restaurant.
a. Write an expression to show how to find the total number of oranges ordered.
b. Next week, Mr. Lee will double the number of boxes he orders. Write a new expression to represent the number of oranges in next week’s order.
c. Evaluate your expression from Part (b) to find the total number of oranges ordered in both weeks.
Answer:
a)480
b)960
c)1440
Step-by-step explanation:
We are given the following information:
Number of oranges in a box = 24
a)Boxes ordered by Lee for his store = 8
Number of boxes ordered by Lee for his restaurant = 12
Total number of oranges ordered = Total number of boxes ordered × Number of oranges in 1 box
[tex]= (8+12)\times 24 = 20\times 24 = 480[/tex]
b) Now Mr. Lee doubled his order for next week.
Boxes ordered by Lee for his store = 16
Number of boxes ordered by Lee for his restaurant = 24
Total number of oranges ordered = Total number of boxes ordered × Number of oranges in 1 box
[tex]= (16+24)\times 24 = 40\times 24 = 960[/tex]
c) Total number of oranges ordered =
[tex](20\times 24) + (40\times 24) = (20+40)\times 24 = 1440[/tex]
Therefore, total 1440 oranges were ordered by Mr. Lee.

A dog is standing on a cliff 20 feet above sea level. A dolphin is swimming 6 feet below sea level. An octopus is moving along the seabed, 30 feet below sea level. What is the elevation of the dog, dolphin and octopus?
Plz help!!!!
Answer:
Dog: 20
Dolphin: -6
Octopus: -30
Step-by-step explanation:
The dog is at 20 because it is above sea level meaning it is above the zero, meaning it is plus +
The dolphin is at -6 because it is below sea level meaning it is below zero meaning its a negative -
The octopus is at -30 because it is below sea level meaning it is below zero meaning its a negative -
(Any Thing Below Zero is a Negative & Anything Above Zero is a Positive)
The elevation of the dog is 20 feet.
The elevation of the dolphin is -6 feet.
The elevation of the octopus is -30 feet.
Given,
A dog is standing on a cliff 20 feet above sea level.
A dolphin is swimming 6 feet below sea level.
An octopus is moving along the seabed, 30 feet below sea level.
We need to find out what is the elevation of the dog, dolphin, and octopus.
How do we describe elevation?When we measure the distance we always measure it from the sea level.
The distance measured below the sea level is always described as a negative value.
The distance measured above sea level is always described as a positive value.
We have,
A dog is standing on a cliff 20 feet above sea level.
This is above sea level so we can describe it as:
The elevation of the dog is 20 feet.
A dolphin is swimming 6 feet below sea level.
This is below sea level so we can describe it as:
The elevation of the dolphin is -6 feet.
An octopus is moving along the seabed, 30 feet below sea level.
This is below sea level so we can describe it as:
The elevation of the octopus is -30 feet.
Thus,
The elevation of the dog is 20 feet.
The elevation of the dolphin is -6 feet.
The elevation of the octopus is -30 feet.

The shape described is a square, having four sides, two pairs of parallel sides, and four right angles, making it two sides fewer than a hexagon.
The shape you are referring to is one with four sides, two pairs of parallel sides, and four right angles. A hexagon has six sides, so a shape with two fewer sides would have four sides. This description matches that of a rectangle. However, since all angles are right angles, which is 90 degrees, this particular rectangle is also a square. Therefore, the pattern block shape you are asking about is a square, which fits the criteria of having two fewer sides than a hexagon, two pairs of parallel sides, and four right angles.

After dilated by a scale factor of 3 using the origin as the centre the point P(6, 2) become P'(18, 6) option (D) is correct.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have an angle PQR is dilated by a scale factor of 3 using the origin as the centre.
Here the point P is not given, so we are assuming the point P is (6, 2)
After dilated by a scale factor of 3 using the origin as the centre:
P' = (6×3, 2×3)
P' = (18, 6)
Thus, after dilated by a scale factor of 3 using the origin as the centre the point P(6, 2) become P'(18, 6) option (D) is correct.

SV is an angle bisector of ∠RST. If m∠RSV = (2x + 8)° and m∠RST = (6x − 26)°, find x.
Answer:
x = 21
Step-by-step explanation:
Given that SV is the angle bisector of ∠RST, then
∠RSV = ∠TSV, thus
∠RSV + ∠TSV = ∠RST ← substitute values
2x + 8 + 2x + 8 = 6x - 26, that is
4x + 16 = 6x - 26 ( subtract 6x from both sides )
- 2x + 16 = - 26 ( subtract 16 from both sides )
- 2x = - 42 ( divide both sides by - 2 )
