If the side's measure is 30 centimeters, then the side of a square measures 3 decimeters, is the "if-then" form of A side of a square measures 3 decimeters if the side's measure is 30 centimeters.
A statement with an assumption and a conclusion is known as a conditional statement (also known as an if-then statement). The hypothesis is the initial clause, or "if," part of a conditional statement which is followed by the second, or "then," component of a conditional statement is the conclusion. The theory led to the conclusion.
Thus, option B is correct which is, if the side's measure is 30 centimeters, then the side of a square measures 3 decimeters.

8 yard. How many yards of material does Jack have left?
Jack has left with the 19/8 yards fraction part of material.
What is Yards?In mathematics, yard is the unit of length. we can say that yard is the one of the measurement of length. Conversion of yard in various quantities is as below:
In inches :1 yard = 36 inches
In feet :1 yard = 3 feets
In meters :1 yard = 0.914 meters
For the question given,
If we have to find the remaining material that has been left we must find the difference between the two i.e. used and purchased material by simply subtracting them.
So, Material purchased = 3 yards
Material used = 5/8 yards
now, material left = Material purchased - material used
= 3 - 5/8
= 19/8 yards
Thus, Jack has left with the 19/8 yards material.

What is the equation?An equation is a mathematical statement composed of two expressions joined by an equal sign. An equation is 3x - 5 = 16. By solving this equation, we obtain the value of the variable x as x = 7.To find the correct number of questions:
Let, 5-point questions are x and 15 marks questions are y.
So, x + y = 14. ...(1)The total points are 100 so the other equation will be:
5x + 15y = 100 ...(2)Now, multiply equation (1) by 5 and then subtract it by equation (2) as follows:
Therefore, there are 11 questions worth 5 points and 3 questions worth 15 points.
5 (x + y = 14) ⇒ 5x + 5y = 70Now,
5x + 5y - 70 - 5x - 15y + 10010y = 30y = 3So, questions worth 15 marks are 3 then, and questions worth 5 marks will be 14 - 3 that is 11.

i need it in 4 steps and what you are doing in each step.
Answer:
x = 8
Step-by-step explanation:
Solve for x:
-2 x + 16 = 4 (x/4 - 2)
Put each term in x/4 - 2 over the common denominator 4: x/4 - 2 = x/4 - 8/4:
-2 x + 16 = 4 (x/4 - 8/4)
x/4 - 8/4 = (x - 8)/4:
-2 x + 16 = 4 ((x - 8)/4)
(4 (x - 8))/4 = 4/4×(x - 8) = x - 8:
-2 x + 16 = x - 8
Subtract x from both sides:
(-2 x - x) + 16 = (x - x) - 8
-2 x - x = -3 x:
-3 x + 16 = (x - x) - 8
x - x = 0:
-3 x + 16 = -8
Subtract 16 from both sides:
(16 - 16) - 3 x = -16 - 8
16 - 16 = 0:
-3 x = -16 - 8
-16 - 8 = -24:
-3 x = -24
Divide both sides of -3 x = -24 by -3:
(-3 x)/(-3) = (-24)/(-3)
(-3)/(-3) = 1:
x = (-24)/(-3)
The gcd of -24 and -3 is -3, so (-24)/(-3) = (-3×8)/(-3×1) = (-3)/(-3)×8 = 8:

The least amount of money you can spend to buy the same number of candles and mints is $125.
The prime factorization of 12 and 15 is:
12= 2*2*3

Now the factor of both appears in both number's factorization so least common multiple is:
LCM of 12 and 15 = 2*2*3*5*5=300
It is given that candies come in packs of 12 and mints in packs of 50.
Hence, the total quantity of packs of each thing is:
Candles: 300÷12=25
Mints: 300÷50=6
The least amount of money to be spent is:
25×$3.50 + 6×$6.25= $87.5 + $37.5= $125

answers to the nearest cent if necessary.
The total amount that she will have to pay back at the end of 10 months is $11,385.864.
We have Sophia .who borrowed $11,020.
We have to determine the total amount that she will have to pay back at the end of 10 months.
What is the formula to calculate the Simple Interest ?The Simple interest can be calculated using the formula -
S.I. = (P x R x T)
where -
P = Principle amount
R = Rate of interest
T = time in years
According to the question -
P = $11020
R = 4%
T = 10 months = 0.83 years
Therefore -
Interest = (P x R x T) = (11020 x 0.04 x 0.83) = $365.864
Now -
Interest = Total amount - Principle
Total Amount = Interest + Principle = 11020 + 365.864 = $11,385.864
Hence, the total amount that she will have to pay back at the end of 10 months is $11,385.864.
