The given question is a typical example of mathematical puzzles. Mathematical puzzles are mathematical problem given to pupils, students for recreational experience and more.
Further ExplanationMathematical puzzles further enhance the creativity of students, as it deals with their logical reasoning.
Mathematical puzzles also has do with the practical usage of order of operations i.e. BODMAS (which is an acronym of Bracket, Of, Division, Multiplication, Addition, Subtraction) to derive solutions for existing problems.
It can be observed from the above given mathematical puzzle expression that Multiplication and Addition are in use in that order.
The two figures are multiplied and added together and then placed together to derive a final
5 + 3 = 158
5 x 3 ~ 5 + 3 = 15 ~ 8 = 158
9 + 1 = 910
9 x 1 ~ 9 + 1 = 9 ~ 10 = 910
8 + 6 = 4814
8 x 6 ~ 8 + 6 = 48 ~ 14 = 4814
4 + 4 = 168
4 x 4 ~ 4 + 4 = 16 ~ 8 = 168
Therefore,
7 + 3 = 2110
7 x 3 ~ 7 + 3 = 21 ~ 10 = 2110

Scientists believe that there is an extremely massive black hole at the center of the Milky Way. How many times more massive than the Sun would a black hole with a mass of 7.36 x 10^36 kg be? The mass of the Sun is approximately 1.99 x 10^30 kg.
A. 3.7 x 10^8
B. 3.7 x 10^6
C. 3.7 x 10^4
D. 3.7 x 10^3
Final answer:
To find out how many times more massive than the Sun a black hole with a mass of 7.36 x 10³⁶ kg is, divide its mass by the mass of the Sun which is approximately 1.99 x 10³⁰ kg. The answer is 3.7 x 10⁶ times more massive than the Sun.
Explanation:
Scientists believe that there is an extremely massive black hole at the center of the Milky Way. To find out how many times more massive than the Sun a black hole with a mass of 7.36 x 10³⁶ kg is, you can divide its mass by the mass of the Sun. So, 7.36 x 10³⁶ kg / 1.99 x 10³⁰ kg = 3.7 x 10⁶ times more massive than the Sun.

A snail moves 1/40 of a mile in 3/4 of an hour. If the snail continues at this pace, how far, in miles, does it move in one hour?
The answer is .03 or 1/30 but, Idk how to explain my answer.
A snail moves 1/40 of a mile in 3/4 of an hour. If the snail continues at this pace, how far, in miles, does it move in one hour?
In [tex] \frac{3}{4} [/tex] hour snail moves [tex] \frac{1}{40} [/tex]miles
[tex] \frac{3}{4} hour = \frac{1}{40} [/tex] miles
Let us multiply by 4 on both sides, so that we can get the distance to be traveled in 1 hour.
So, [tex] \frac{3*4}{4} hour=\frac{1*4}{40} [/tex] miles
[tex] \frac{3*1}{1} hour=\frac{4}{40} [/tex] miles
Now to get distance in 1 hour, Let us divide by 3 on both sides
[tex] \frac{3}{3} hour=\frac{1}{10*3} [/tex] miles
[tex] \frac{1}{1} hour=\frac{1}{30} [/tex] miles
In 1 hour, the snail travels [tex] \frac{1}{30} [/tex]miles

Problem Nell's mom makes chocolate milk with 30mL of chocolate syrup for every 2 ounces of milk. Nell's dad adds 65mL of chocolate syrup for every 5 ounces of milk. Whose chocolate milk is more chocolatey?
a- Nell's Mom
b-Nell's Dad
c- They're both equally chocolately
12 POINTSS
Answer:
(A) Nell's mom
Step-by-step explanation:
It is given that Nell's mom makes chocolate milk with 30mL of chocolate syrup for every 2 ounces of milk.
⇒For 1 ounce of milk, she will make chocolate milk=[tex]\frac{30}{2}=15mL[/tex]
Also, it is given that Nell's dad adds 65mL of chocolate syrup for every 5 ounces of milk.
⇒For 1 ounce of milk, he will make chocolate milk=[tex]\frac{65}{5}=13mL[/tex]
Since, Nell's mom made 15mL of chocolate milk and his dad made 13mL of chocolate milk, thus Nell's mom made chocolate milk more chocolatey.
Hence, option A is correct.

Julio is in Colorado exploring part of the Denver Zoo as shown he starts at the felines exhibit and travels 3 unit to the right and 5 units up at which exhibit is Julio located at the felines exhibit is located at (3,1) what are the coordinates of Julio's new location
To find Julio's new location at the Denver Zoo, we add his horizontal and vertical movements to his starting coordinates. After moving 3 units to the right and 5 units up from the felines exhibit at (3,1), Julio's new location is at coordinates (6,6).
Explanation:The student is asking about a basic coordinate geometry problem. Julio is at the felines exhibit at coordinates (3,1). To find Julio's new location after traveling 3 units to the right and 5 units up, we add the horizontal and vertical movements to his starting coordinates.
The movement to the right corresponds to an increase in the x-coordinate, while the movement up corresponds to an increase in the y-coordinate. Starting from the point (3,1), moving 3 units to the right means the x-coordinate changes from 3 to 3 + 3 = 6. Moving 5 units up means the y-coordinate changes from 1 to 1 + 5 = 6. Thus, Julio's new coordinates are (6,6).
How is the following decimal number read?
28.9
A. Twenty and eight-nine tenths
B. Twenty-eight and nine hundredths
C. Twenty-eight and nine tenths
D. Twenty-eight nine
Answer:
C. Twenty-eight and nine tenths.
Step-by-step explanation:
We have been given a decimal number [tex]28.9[/tex]. We are asked to choose the correct option that represents how to read our given decimal number.
Upon looking at our given decimal number we can see that it has one digit at tenth place that is 9, which represents that our number has 9 tenths.
The two digits before decimal are 2 (tens place) and 8 (ones place). These digits make 28.
Therefore, the given decimal number could be read as twenty-eight and nine tenths and option C is the correct choice.

Exponents and exponential functions unit test
1. -(10)^-1
A)-1/10
B)-1/-1^10
C)1/10
D)10
Answer:
A
Step-by-step explanation:
We can change the sign of an exponent if we change sides. This means sign of exponent changes when we move the number (along with base) from numerator to denominator or from denominator to numerator.
So 10 to the power -1 will change to 10 to the power 1 if we take the whole thing to the denominator (steps shown below):
[tex]-(10)^-1\\=-\frac{1}{10^1}\\=-\frac{1}{10}[/tex]
