Step-by-step explanation:
Notice that the transformation from to
involves a reflection around the
axis.
Therefore we should draw a similar semicircle starting at (0,0) and ending at (4,0) and with radius 2 as seen in the attached image.

6 sisters ... 4 sandwiches
1 girl ... x sandwiches = ?
6 * x = 4 * 1
6 * x = 4 /6
x = 4/6
x = 2/3
The correct result would be 2/3 of a sandwich.

Answer:
13 units
Step-by-step explanation:
Use the pythagorean theorem and find the hypotenuse.
a^2 + b^2 =c^2
Draw the triangle by connecting the dots so you can see the legs.
one leg is 8 units and one leg is 10 units
8^2 + 10^2 = c^2
64 +100= c^2
164 = c^2
Find the square root of 164 which is 12.8. Round to 13

What is division?
Division is the process by which value of single unit can be calculated from the value of multiple unit.
The number to be divided is known as dividend, the number by which the dividend is divided is the divisor, the result obtained is the quotient and the remaining part is the remainder.
There is a well known formula for division
Divisor x Quotient + Remainder = Dividend.
Here,
Total number of problems given on Monday = 45
Number of days from Monday to Friday = 5
Number of problems Helen solve on Friday = = 9

Option A is the correct answer.
What is a chemical reaction?
A chemicalreaction is a process that leads to the transformation of one set of chemical substances into another.
In other words, it is the process of breaking and forming chemical bonds between atoms to create new compounds with different properties than the original substances.
We have,
An endothermicreaction is a type of chemical reaction that absorbs heat from the surrounding environment, resulting in a decrease in temperature.
In this case,
The chemicalreaction that occurred in the test tube absorbed heat from the surroundings, including the air and the test tube itself.
As a result, the temperature of the test tube decreased, making it feel cold to the touch.
Thus,
The testtube is cold best describes what is felt.

Final answer:
In an endothermic reaction, the test tube will feel cold because heat is absorbed by the system from the surroundings.
Explanation:
A chemical reaction or physical change is endothermic if heat is absorbed by the system from the surroundings. In the course of an endothermic process, the system gains heat from the surroundings, and so the temperature of the surroundings decreases.
The quantity of heat for a process is represented by the letter q. The sign of q for an endothermic process is positive because the system is gaining heat.
A chemical reaction or physical change is exothermic if heat is released by the system into the surroundings. Because the surroundings are gaining heat from the system, the temperature of the surroundings increases.
The sign of q for an exothermic process is negative because the system is losing heat.
