explain why the length of ac is 13 cm

Explain Why The Length Of Ac Is 13 Cm

Answers

Answer 1

Answer:

AC=13cm

AD=13,9cm

Step-by-step explanation:

a)Pythagoras' Theorem in ABC, right-angle triangle

AC²=AB²+BC²

AC²=144cm²+25cm²=169cm²

AC=13cm

b)ACD is right-angle triangle

AD²=AC²+CD²

AD²=169cm²+25cm²=194cm²

AD=√194cm

AD=13,9CM

Answer 2

Answer:

Step-by-step explanation:

ABC is a right triangle

So,

AC² = AB² + BC²

= (12 cm)² + (5 cm)²

= 144 cm² + 25 cm²

AC² = 169 cm²

AC = 13 cm

So you want to finance a car for $4,840. Let’s say we offer you a 4.5% interest rate on a 2-year loan and 6% on a 5-year loan. Enter this info into the calculator to see your monthly and total cost by loan term.

Answers

6% = .6

4840 x .06 = 290.4

290.4+ 4840 = 5130.4

5130.4 ÷ 24 = 213.766666667

$5130.40 is your total cost by loan term.

$213.77 is APPROXIMATELY your monthly total for 2 years.

For the 2 year loan, onthly payments is $211.26 and Total payment is $5070.12.

For the 5 year loan, Monthly payments is $93.57 and Total payment is $5614.21.

What is the monthly total cost of the loan?

Assuming the loan is compounded monthly, the total monthly payment is calculated from the amortization loan formula as follows:

[tex]A=\frac{P(i(1+i)^n)}{((1+i)^{n-1})}[/tex]

where:

A = monthly paymentP = amount borrowed = $6000i = monthly interestn = number of months

Calculating the monthly payment for the 2 year loan:

i = monthly interest = 0.045/12

n = number of months = 2 × 12 = 24 months

[tex]A = \frac{4840(0.045/12 (1 +.045/12)^{24})}{((1 +.045)^{24-1})} = \$211.26[/tex]

Monthly payments = $211.26

Total payment = $5070.12

Calculating the monthly payment for the 5 year loan:

i = monthly interest = 0.06/12

n = number of months = 5 × 12 = 60 months

[tex]A = \frac{4840(0.06/12 (1 +.006/12)^{60})}{((1 +0.06)^{60-1})} = \$93.57[/tex]

Monthly payments = $93.57

Total payment = $5614.21

Therefore, the monthly payments are calculated using the amortization loan formula.

Find the measure of the angel. n=_°

Answers

Answer:

n = 25°

Step-by-step explanation:

All interior angles of a triangle add up to 180°. We already know one of the angles is 90°, so we can build an equation:

90 + (n + 40) + n = 180.

Then we combine like-terms and subtract:

130 + 2n = 180,

2n = 50.

Then we divide by 2 to get our answer:

n = 25.

To double check, we insert 25 as our value:

90 + (40 + 25) + 25 = 180.

Step-by-step explanation:

The equation of a circle can be written as

(x-h) ^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

(x-1) ^2 + (y- -4)^2 = 2^2

The points plotted below are on the graph of a polynomial. Which of the following x-values best approximate roots of the polynomial. check all that apply ​

Answers

Answer:

The correct options are:

x= -1.1

x= 2.4

x = 6

Step-by-step explanation:

The roots of any polynomial can easily be determined by the graph. To find the roots from the graph, we just have to see the values of x, for which the value of whole polynomial becomes 0.

We can see in the graph that there are three points where the value of polynomial becomes 0. that are

At x= -1.1

At x= 2.4

At x = 6

Thus, these are the roots

Mehrine and Zaara brought an equal amount of money to the shopping mall. Mehrine spent Rs 500 on a pair of shoes and Zaara bought a dress for Rs 2000. After their shopping, Zaara has ⅔ of what Mehrine had left. How much money did Mehrine bring for shopping?​

Answers

Answer:

Rs5000

Step-by-step explanation:

Let the equal amount of money they both brought = x

Mehrine spent Rs 500 on a pair of shoes, therefore, the money Mehrine has left

= x-500

Zaara bought a dress for Rs 2000, therefore, the money Zaara has left

= x-2000

Zaara has ⅔ of what Mehrine had left.

Therefore:

[tex]x-2000=\dfrac{2}{3} (x-500)[/tex]

Cross multiply

3(x-2000)=2(x-500)

3x-6000=2x-1000

3x-2x=6000-1000

x=5000

Therefore, Mehrine brought Rs5000 for shopping.

The average of an electrician's hourly wage and a plumber's hourly wage is $33. One day a contractor hires an electrician for 9hr of work and the plumber for 6hr of work and pays a total of $468 in wages. Find the hourly wage for the electrician and for the plumber. Electrician makes $___ and Plumber makes $___

Answers

Answer:

Plumer : $198

Electrition : $270

Step-by-step explanation:

The Electrician makes $ 216 and Plumber makes $ 252

The hourly wage of the electrician = $ 24

The hourly wage of the plumber = $ 42

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the hourly wage of electrician be = $ x

Let the hourly wage of plumber be = $ y

The average of hourly wage of an electrician and plumber = $ 33

So , ( x + y ) / 2 = 33

Multiply by 2 on both sides , we get

x + y = 66   be equation (1)

And , One day a contractor hires an electrician for 9hr of work and the plumber for 6hr of work

So , total wages =
9 hours of work by electrician + 6 hours of work by plumber

9x + 6y = $ 468   be equation (2)

Now , we have 2 equations

Multiply equation (1) by 6 , we get

6x + 6y = 396   be equation (3)

And ,

equation (2) - equation (3) , we get

3x = 72

Divide by 3 on both sides , we get

x = 24

Substituting the value of x in equation (1) , we get

y + 24 = 66

Subtracting 24 on both sides, we get

y = 42

So , the hourly wage of electrician is $ 24 and the hourly wage of plumber is $ 42

Now , wage of electrician for 9 hours = 24 x 9

                                                              = $ 216

Wage of plumber for 6 hours = 42 x 6

                                                 = $ 252

So total wage = 216 + 252 = $ 468

Hence , the electrician makes $ 216 and plumber makes $ 252

literally a free 50 points, just need the answer, What is the solution to the equation fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n?

Answers

Answer:

n = 1/2

Step-by-step explanation:

So the equation is 4/5n - 1/5 = 2/5n.

So, the first thing that we need to do is get the variable on one side.

So, to do that we need to subtract 4/5n on both sides.

Now our equation is -1/5 = -2/5n

Now the last step is to simplify.

To do that, we need to multiply by the reciprocal of 2/5 on both sides.

That leaves us with 1/2 = n

Answer:

n = 2

Step-by-step explanation:

=> [tex]\frac{4}{5n} - \frac{1}{5} = \frac{2}{5n}[/tex]

Combining like terms

=> [tex]\frac{4}{5n } - \frac{2}{5n} = \frac{1}{5}[/tex]

=> [tex]\frac{4-2}{5n} = \frac{1}{5}[/tex]

=> [tex]\frac{2}{5n}= \frac{1}{5}[/tex]

Cross Multiplying

=> 5n = 2*5

=> 5n = 10

Dividing both sides by 5

=> n = 2

Step-by-step explanation:

c = $30.24

g = 16

Divide c/g

Answer:

g gallon = $1.89 g

Step-by-step explanation:

Gallon = g

16 gallons = 16 g

Cost = $30.24

So,

16 gallons = $30.24

1 gallon = $30.24/16

1 gallon = $1.89

g gallon = $1.89 g

What is Transformation?

Transformation is changing the graph to a new one by Rotation, Reflection, Translation, and Dilation.

Reflection is to create a mirror image of the coordinate or the figure.

After reflection along any axis, the coordinate of the other axis changes to its additive inverse.

(x,y) ----> when reflected along y axis ----> ( -x , y)

The domain is all the values a function can have as input and the range is all the values that a function can have.

The original coordinate changes to  (-1,3),(2,1),(5,-1)and(-1,-2).

When reflected along the y-axis, the coordinates of the x-axis change and there is no change in the y-axis.

So the value of the domain changes while the range remains the same.

The range is { -2 ≤y≤3}
