Answer:

$2400

Step-by-step explanation:

Given data

Principal= $6000

Rate= 8%

Simple interest= ???

Time= 5 years

The expression for the simple interest is

Simple interest= PRT/100

Simple interest= 6000*8*5/100

Simple interest= 240000/100

Simple interest= $2400

Hence the simple interest after 5 years is $2400

Measure of angle V₃ in degree is,

⇒ V₃ = 120°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

Figure of a Hexagon polygon is shown in figure.

We know that;

In a polygon of 'n' sides, the sum of the interior angles is equal to,

(2n - 4) × 90°

Hence, In a polygon of '6' sides, the sum of the interior angles is equal to,

⇒ (2x6 - 4) × 90°

⇒ 8 × 90°

⇒ 720°

Hence, Each angle of polygon is,

⇒ 720°/6

⇒ 120°

Thus, Measure of angle V₃ in degree is,

⇒ V₃ = 120°

Answer:

Multiply row 1 by [tex]\frac{1}{2}[/tex].

Step-by-step explanation:

The augmented matrix of the system of linear equation is described below:

[tex]\left[\begin{array}{cccc}2&1&-1&-8\\0&2&3&-6\\-\frac{1}{2} &1&1&-4\end{array}\right][/tex]

Where [tex]a_{11} = 2[/tex], if we need to create [tex]a_{11} = 1[/tex], we need to multiply row 1 by [tex]\frac{1}{2}[/tex], that is to say:

[tex]\left[\begin{array}{cccc}1&\frac{1}{2} &-\frac{1}{2} &-4\\0&2&3&-6\\-\frac{1}{2} &1&1&-4\end{array}\right][/tex]

Hence, the correct answer is: Multiply row 1 by [tex]\frac{1}{2}[/tex].

The complete question is

The starting salary for a delivery driver is $35,000 per year with a yearly increase of 3%. which type of function best models this situation? a) exponential b) linear c) quadratic d) radical

Solution

After 1 year the salary of delivery boy will be

[tex]35000 + 35000*0.03\\35000+1050\\36050[/tex]

Salary of delivery boy after 2nd year =

Salary after 3rd year

[tex]37131.5 + (37131.5*0.03) = 38245.45[/tex]

The growth in salary is linear as depicted from the values obtained.

Hence, option B is correct

Answer and Step-by-step explanation:

1.

We are told to give the transformations needed to map the triangle ABC onto the triangle XYZ.

First off, we should move the triangle to the right. We need to have point B of triangle ABC to overlap point Y of triangle XYZ.

Once that is done, we need to do a dilation by scale 1.5. This would perfectly align triangle ABC onto triangle XYZ.

2.

To find the length of XZ, we need to find the dilation factor. Since we know that the triangles are similar, we can divide the bigger side by the little side (though only the sides that correspond).

We will divide side CB by ZY to get the dilation scale factor.

6 divided by 4 equals 1.5.

Now, to find the length, we will divide side CA by 1.5.

21 divided by 1.5 equals 14.

The length of ZY is 14.

Explanation:

Refer to the diagram below. I've added the points A, B, C, D, and E. Point A is the center of the circle while points B, C and D are along the circle's edge. The radius AC and chord BD intersect at point E.

Recall that whenever we have a radius perpendicular to a chord like this, it means that the radius bisects the chord. So that means chord BD is cut into two equal pieces BE and ED. The diagram given to you tells us that ED = x, so BE is also x units long as well. Overall, BD = BE+ED = x+x = 2x units.

Since BE = ED, the arcs formed are congruent as well. Minor arc BC is the same measure as minor arc CD. Both are 45 degrees. They combine to 90 degrees. In turn, this leads to central angle DAB to be 90 degrees.

Note how triangle DAB is an isosceles right triangle. The two equal legs are the two radii AB and AD, both which are 9 units long. The hypotenuse BD is equal to sqrt(2) times the leg length, so BD = 9*sqrt(2) units long.

Earlier I mentioned that BD = 2x also. We'll equate the two right hand side expressions and solve for x like so:

2x = 9*sqrt(2)

x = (9*sqrt(2))/2

x = (9/2)*sqrt(2)

x = 4.5*sqrt(2)

x = 6.36396103067892

That value is approximate. Rounding to the nearest tenth leads to the final answer of 6.4; therefore, the answer is choice A.

Move numbers with (x) on one side turning it into (-)

x = 6/5

Step-by-step explanation:

Rearrange unknown terms to the left side of the equation:

 7x − 2x = −1 + 7

Combine like terms:

 5x = −1 + 7

Calculate the sum or difference:

 5x = 6

Divide both sides of the equation by the coefficient of variable: 

x = 6 ÷ 5

Calculate the product or quotient: 

x = 1.2

Express the number in fractions:

 x= 6/5

Step-by-step explanation:

Luke listens to the three most popular songs on the radio this week. The length of each song is shown. #1 song: 3 1/2 minutes #2 song: 2 57 /60 minutes #3 song: 4 3/4 minutes. What is the length of the three songs all together?

song 1: 3 1/2 minutes

song 2: 2 57 /60 minutes

song 3: 4 3/4 minutes

Total length of the three songs = song 1 + song 2 + song 3

= (3 1/2 + 2 57/60 + 4 3/4) minutes

= 7/2 + 177/60 + 19/4

= (210+177+285) / 60

= 672/60

= 56/5

= 11 1/5 minutes

Total length of the three songs = 11 1/5 minutes

Answer:

Part A

The system of equations are;

x = y/18

x + 1/6 = y/13

Part B

13/30 hours

Step-by-step explanation:

The path on which Anita is riding = The path on which Brad is riding

The point at which Anita starts riding = The start of the park

The rate at which Anita is riding = 18 miles per hour

The time at which Bras began = 10 minutes ahead of Anita

The rate at which Brad is riding = 13 miles per hour

Part A

Let 'x' represent the number of hours it takes Anita and Brad to travel 'y' miles along the path, we have;

The 'x' number of hours it takes Anita to travel 'y' miles is given as follows;

x = y/18

For Brad, we have;

10 minutes = 1/6 of an hour

The 'x'' number of hours it takes Brad to travel 'y' miles is given as follows;

x' = y/13

The duration Brad has traveled, when Anita has traveled for 'x'' hours = x + 1/6 hour

x' = x + 1/6

∴ x + 1/6 = y/13

Part B

Therefore, to travel the same 'y' mile as Anita , we have;

x + 1/6 = y/13

y = 13 × (x + 1/6) = 13·x + 13/6

y = 13·x + 13/6

For Anita, we had; x = y/18

∴ y = x × 18 = 18·x

Equating both y-values gives;

y = y

∴ 13·x + 13/6 = 18·x

18·x - 13·x = 5·x = 13/6

x = 13/(5 × 6) = 13/30 hours

The number of hours it will take Anita and Brad to meet on the path = 13/30 hours (equivalent to 13/30 hour × 60 minutes/hour = 26 minutes)

Answer:

x = 6

Step-by-step explanation:

using the Pythagorean theorem:

(4 + x)² = 8² + x²

16 + 8x + x² = 64 + x²

subtract x² and 16 from each side of the equation:

8x = 48

divide both sides by 8:

x = 6

Answer: a) no. The p value of the appropriate test is greater than 0.05

Step-by-step explanation:

The statement "No. The p-value of the appropriate test is greater than 0.05." is a correct option (A) is correct.

It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.

We have:

Sample size n = 400 teachers

Sample mean X = 12.5 hours

Standard deviation S = 6.5 hours

Population mean u = 13 hours

Null hypothesis H0: u = 13

Alternativ hypothesis u <13

T-test:

[tex]\rm t = \frac{x-u}{\frac{s}{\sqrt{n} } }[/tex]

[tex]\rm t = \frac{12.5-13}{\frac{6.5}{\sqrt{400} } }[/tex]

t = -1.5385

Now degree freedom df = n -1  = 400 - 1

df = 399,  α = 0.05

P-value = p[1+t<-1.5385]

P-value = 0.0624

∴ P-value is greater than α because of this the null hypothesis failed.

Thus, the statement "No. The p-value of the appropriate test is greater than 0.05." is a correct option (A) is correct.
