Answer:

x = -232

Step-by-step explanation:

Ronu's present age is "x “years and her sister Shaani's present age is twice  of Ronu's age.

(a) Ronu's present age = x years

(b) Ronu's age after 2 years = (x+2) years

(c) Shaani's present age = 2x years

(d) Shaani's age after 2 years = (2x+2) years

Let x should be added to 100 to get -132.

x+100 = -132

x = -100-132

x = -232

Hence, -232 must be added to 100 to get -132.

Answer:

Width = 10 inches

Step-by-step explanation:

Given the perimeter of a rectangle of 68 inches, and a length that is 14 inches longer than its width.

We can establish the following values to help us solve for the width of a rectangle:

Perimeter (P) = 68 inches

Length (L) = 14 + W inches

Width (W) = unknown

P =  2(L + W)  ⇒ This is the same as P = 2L + 2W, except that 2 is factored out from the right-hand side.

Divide both sides by 2:

\(\displaystyle\mathsf{\frac{P}{2}\:=\:\frac{2(L\:+\:W)}{2}}\)

\(\displaystyle\mathsf{\frac{P}{2}\:=L\:+\:W}\)

Substitute the value of the Perimeter and the length (L) into the formula:

\(\displaystyle\mathsf{\frac{68}{2}\:=14\:+W\:+\:W}\)

Combine like terms on the right-hand side, and simplify the left-hand side of the equation:

\(\displaystyle\mathsf{34\:=14\:+2W}\)

Subtract 14 from both sides:

34 - 14 = 14 - 14 + 2W

20 = 2W

Divide both sides by 2 to solve for the width (W):

\(\displaystyle\mathsf{\frac{20}{2}\:=\:\frac{2W}{2}}\)

W = 10 inches

Therefore, the width of the rectangle is 10 inches.

Verify whether the derived value for the width is correct:

P = 2L + 2W

68 = 2(14 + 10) + 2(10)

68 = 2(34) + 20

68 = 48 + 20

68 = 68 (True statement).  

Thus, the length of the rectangle is 34 inches, and the width is 10 inches.

We want to find the value of \(f(g(x)).\) To do this, we plug in \(g(x)\) into the expression for \(f(x).\) This gives us:

\(f(g(x)) = (x^2-9)^2+7(x^2-9)+12 = x^4-18x^2+81+7x^2-63+12 = \boxed{x^4-11x^2+30}.\)

Based on the method of solutions of equations, the number of Trucks carrying the fruits are as follows:

The solution of an equation makes the equation true.

From the data provided:

36 trucks went out carrying early peaches:

62 carried late peaches;

57 carried extra late peaches,

23 carried early and late,

30 carried late and extra late,

13 carried early and extra late,

4 carried all three:

7 carried only figs (no peaches at all).

The number of trucks that carry only late variety peaches:

Late Peach only = 63 - (30 - 4) - (24 - 4)

Number of Trucks that carried only extra late variety peach:

Extra late Peach only = 57 - (30 - 4) - (13 - 4)

Number of Trucks that carried only one type of peach?

Early Peach only = 36 - (13 - 4) - (23 - 4)

Early Peach only = 8 trucks

Then;

Number of Trucks that carried only one type of peach = 17 + 22 + 8

Total number of trucks that went out during the week:

Total number of Trucks = 47 + (13 - 4) + (23 - 4) + (30 - 4) + 7

The main difference between the random walk of a gas molecule and that of a protein molecule in water is that the gas molecule will have a lower random walk.

When there is a high frequency of molecules, as is the case in a liquid, there will be more random walks because molecules will keep bumping into each other. In gas however, the random walk will be less because molecules are more spaced out.

In conclusion, the gas molecule will have less random walk.

They may bake 20 additional bags of cookies. The problem is represented by the inequality x < 80.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given, A bakery wants to bag at most 100 cookies into cookie packs. Each cookie pack has 4 cookies. They have already bagged 20 cookies.

Since each cookie pack can hold 4 cookies

Thus, 100 cookies will require = 100/4 packs

100 cookies will required = 25 packs

Since They have already bagged 20 cookies.

Thus,

The total pack they used = 20/4

The total pack they used = 5

Inequality:

let "x" be the number of cookies they can make

80 > x

Therefore, 20 more bags of cookies they could make. the inequality that represents the situation is x< 80.

The approximate population in 2016 is 91, 604 population

The exponential equation representing the statement is \(P=P_0e^t\)

Substituting into the formula will give:

If by 2012 the population had increased to 81,000, then:

81000 =  56000e^12k

81000/56000 = e^12k

1.4464 = e^12k

ln1.4464 = 12k

0.3691 = 12k

k = 0.3690/12

k = 0.03076

Get the prediction of the population in 2016.

\(P = 56000e^{16(0.03076)}\\P=56000e^{0.49213}\\P = 56000(1.6357)\\P = 91,603.70\)

Answer:

\(A_{shaded} = 106\ m^2\)

Step-by-step explanation:

Step 1:  Get the area of the inside box

\(A=l*w\)

\(A_{inside\ box} = 7\ m* 2\ m\)

\(A_{inside\ box} = 14\ m^2\)

Step 2:  Get the area of the outside box

\(A = l * w\)

\(A_{outside\ box} = 12\ m * 10\ m\)

\(A_{outside\ box} = 120\ m^2\)

Step 3:  Subtract the inside box from the outside box

\(A_{shaded} = A_{outside\ box} - A_{inside\ box}\)

\(A_{shaded} = 120\ m^2 - 14\ m^2\)
