What we can find here first is the rate of the increase of the salary of the workers. We can use the equation

We are looking for the value of r. We have to derive an equation solving for r. We have

Now, we solve for the value of r given y = 29.59, y0 = 6.70, and t = 15 years. We get

The doubling time is computed as

Substitute the value of r on the equation above and solve, we get

Hence, the doubling time for this problem is equal to 7 years.

Answer: 7 years

Answer:

14

Step-by-step explanation:

well, the logic is simply that the sum of the parts must be the same as the whole.

so,

8 + (x + 2) = 4x - 2

10 + x = 4x - 2

12 = 3x

x = 4

therefore,

MK = 4x - 2 = 4×4 - 2 = 16 - 2 = 14

⇒Plug in the given values of the variables in order and then simplify the expression

Given that a= 3 and b=4

⇒[tex]=(3)^{3} -(4)+7\\=27-4+7\\=23+7\\=30[/tex]

⇒The expression evaluated at the given known variables gives 30.

The area of the walkway in square yards is 22.77 yards²

The cost of painting the walkway will be $85.37.

The square yards of the walkway can be determined by adding the areas of the two rectangles and the area of the quarter of a circle together.

Area of a rectangle = length x width

Area of the first rectangle = 9.5 x 1.5 = 14.25 yards²

Area of the second rectangle = 4.5 x 1.5 = 6.75 yards²

Area of a circle = πr²

Area of quarter of a circle = 1/4 ×  πr²

Where:

π = pi = 3.14

r = radius

1/4 x (3.14 x 1.5²) = 1.77 yards²

Area of the walkway = 1.77 yards² + 6.75 yards² +  14.25 yards² = 22.77 yards²

The cost of the painting can be determined by multiplying the area of the walkway by the cost per square yard.

Total cost = 22.77 yards² x 3.75 = $85.37

It is important the order we write the vertices of a triangle in a congruent statement as

B. The order tells us what sides are congruent.

D. The order tells us what angles are congruent.

A vertex (plural vertices) in geometry is the intersection of two straight lines. Three line segments come together to form a triangle. The ends of a triangle's three sides meet at three separate points in a plane to form the triangle, which has three sides with two endpoints each. The vertices of a triangle are the three distinct intersecting points or corners.

Congruent triangles are triangles that are precisely the same size and shape. The word congruent has the sign. When the three sides and three angles of one triangle match the same dimensions as the three sides and three angles of another triangle, two triangles are said to be congruent.

The vertices of a triangle in a congruent statement are important for the ordering. In conclusion, the correct options are B and D.

Answer:

1 Greatest Common Factor

We have to find out the greatest common factor, of the given polynomial to factorise it. This process is nothing but a type of reverse procedure of distributive law.

2. Grouping

This method is also said to be factoring by pairs. Here, the given polynomial is distributed in pairs or grouped in pairs to find the zeros.

3. Using Identities

The factorisation can be done also by using algebraic identities. The most common identities used in terms of the factorisation are:

(a + b)2 = a2 + 2ab + b2

(a – b)2 = a2 – 2ab + b2

a2 – b2= (a + b)(a – b)

4. Zero Factor Property :The Zero Factor Property (also called the Zero Product Property) says that if the product of two quantities is zero, then at least one of those quantities is zero. The only way to get a product equal to zero is to multiply by zero itself.

5. Greatest Common Factor (GCF) Method:

This is almost always the first method applied to factoring polynomials. Look at all of the terms and see if they all have something in common that can be removed.

Step-by-step explanation:

The probability of a gorilla living less than 23.9 years is 0.84 (84%) if the lifespans of gorillas in a particular zoo are normally distributed.

A probability is also called as a numerical representation of the likelihood or chance that any kind of specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities. Probability refers to potential.

Any random event's occurrence is the exact subject of this area of mathematics. The range of the value varies from 0 to 1. Mathematics has been incorporated probability to forecast the likelihood of various types of events.

The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas.

We need to find the z-score herein of 23.9 years in the kind of standard normal distribution of the lifespans of gorillas in this particular zoo.

z score can be further be calculated using the equation

z = (X-M)/s

and it has been given that X is 23.9 years

M is also called the average gorilla life (20.8 years)

s is given as the standard deviation (3.1 years)

Thus, putting up the values, we have

Z = 1

The Empirical rule that is present here states that 68% of the total lifespans lie within 1 standard deviation from the other mean.

Then Half of it, 68/2 = 34 % lies right side of 1 standard span of the mean.

Since this lifespan is less than mean is 50%, 50%+34% =84% lies less than total z-score 1, that is the probability of a gorilla living less than 23.9 years.

When in triangle ABC, angle B is one quarter off angle B and angle C is two fifth of angle A and the angle A is (x-10)  degrees, then the ∠A, ∠B  and ∠C  are 109 degrees, 27 degrees and 44 degrees respectively  

The ∠A = (x-10) degrees

Angle B is one-quarter of angle A

∠B = (1/4)×(x-10)

= (1/4)x - (5/2)

= 0.25x-2.5

The angle C is two fifth of angle A

∠C = (2/5)(x-10)

= (2/5)x - 4

= 0.4x-4

We know sum of the angles in a triangle is 180 degrees

Then,

∠A + ∠B + ∠C = 180

Substitute the values in the equation

(x-10) + 0.25x-2.5 +0.4x-4 = 180

1.65x-16.5 = 180

1.65x = 196.5

x ≈ 119

∠A = (x-10)

= 119-10

= 109 degrees

∠B = 0.25x-2.5

= 0.25×119-2.5

≈ 27 degrees

∠C = 0.4x-4

= 0.4×119-4

≈ 44 degrees

Hence, when in triangle ABC, angle B is one quarter off angle B and angle C is two fifth of angle A and the angle A is (x-10)  degrees, then the ∠A, ∠B  and ∠C  are 109 degrees, 27 degrees and 44 degrees respectively

The addition of the fraction 1/10 + 11/20 based on the computation will be 13/20.

In mathematics, a fraction is defined as a portion of the whole. If a pizza is cut into four equal pieces, each slice is represented by ¼.

It should be noted that a fraction simply means a part of a whole number. It should be noted that it's usually expressed as a/b where a is the numerator and b is the denominator.

In this case, we want to add 1/10 + 11/20. This will be illustrated thus:

= 1/10 + 11/20

= 2/20 + 11/20
