The diagram shows a cone of the height of 5 cm and a base radius of 12 cm
What is the total surface area of the side and base?
Use 3.14 as an approximation for IT

Answers

Answer:

radius r = 12 m

height h = 5 m

slant height s = 13 m

volume V = 753.982237 m ³

lateral surface area L = 490.088454 m²

base surface area B = 452.389342 m²

total surface area A = 942.477796 m²

The total surface area of cone is 942 cm².

What is Total surface area of Cone?

Total surface area is the sum of the area of the circular base and the area of the curved part of the cone.

The total surface area of a cone is the sum of the area of the base and the lateral area:

  SA = πr² + πrl

where, r is radius

           l is slant height

Now, for finding the slant height of the given cone is

         l² = r² + h²

         l² = 12² + 5²

         l² = 144 + 25

        l² = 169

        l = 13 cm

Now, SA = π X 12² + π X 12 X 13

              = 144π + 156π

              = 300π

              = 300 X 3.14

              = 942 cm²

Thus, the total surface area of cone is 942 cm².

5x + 2y = 8
-4x + 10y = 40

Answers

Answer:

(0, 4 )

Step-by-step explanation:

5x + 2y = 8 → (1)

- 4x + 10y = 40 → (2)

multiplying (1) by - 5 and adding to (2) will eliminate y

- 25x - 10y = - 40 → (3)

add (2) and (3) term by term to eliminate y

- 29x = 0 , then

x = 0

substitute x = 0 into (1) and solve for y

5(0) + 2y = 8

0 + 2y = 8

2y = 8 ( divide both sides by 2 )

y = 4

solution is (0, 4 )

The $23 rd term in a certain geometric sequence is 16 and the $28th term in the sequence is 24. What is the $43 rd term?

Step-by-step explanation:

Geometric sequence formula:  [tex]a_n=ar^{n-1}[/tex]

Given:

[tex]a_{23}=ar^{22}=16[/tex][tex]a_{28}=ar^{27}=24[/tex]

Find common ratio (r):

[tex]\begin{aligned}\implies \dfrac{a_{28}}{a_{23}} =\dfrac{ar^{27}}{ar^{22}} & =\dfrac{24}{16}\\ \implies r^5 & =\dfrac32\\ \implies r & = \sqrt[5]{\frac32} \end{aligned}[/tex]

Find initial term (a):

[tex]\implies ar^{22}=16[/tex]

[tex]\implies a(\sqrt[5]{\frac32} )^{22}=16[/tex]

[tex]\implies a(\frac32} )^{\frac{22}{5}}=16[/tex]

[tex]\implies a=\dfrac{16}{(\frac32)^{\frac{22}{5}}}[/tex]

Find the 43rd term:

[tex]\implies a_{43}=ar^{42}[/tex]

[tex]\implies a_{43}= \left(\dfrac{16}{(\frac32)^{\frac{22}{5}}}\right)(\sqrt[5]{\frac32} )^{42}[/tex]

[tex]\implies a_{43}=16 \cdot (\frac32)^{-\frac{22}{5}} \cdot (\frac32)^{\frac{42}{5}}[/tex]

Step-by-step explanation:

     The solution is the point of intersection.

Here, the lines intersect at the point (0, 9) in the format of (x, y) so we can pull out the answers x = 0 and y = 9.

Answer:

(0, 9)

Step-by-step explanation:

First we need to find the equations of each line!What I'd do is use the equation:gradient (m) = change in y ÷ change in xStarting with the left line, let's pick two coordinates that are on the lineI've picked: (-2, 5), (-3, 3)gradient (m) = (3 - 5) ÷ (-3 - -2) = -2 ÷ -1 = 2We can then use the equation y = mx + c  (m is gradient)y = 2x + cWe know we have the point (-3, 3) on this line(-3, 3) = (x, y)  so  x = -3  and  y = 3y = 2x       + c3 = 2 × -3 + c3 = -6 + cc = 9Finally, we can say y = 2x + 9

Doing the exact same steps for the other line...

y = -3x + 9Since we now have two  y = ... equationsWe can say y = yWhich is the same as2x + 9 = -3x + 9We rearrange to find x...5x = 0x = 0That gives us the x-coordinate of where the lines meet (the solution of the system of equations)We can then pick either equation to find the y-coordinate:y = -3x + 9y = -3 × 0 + 9 = 9So the solution we have is at the point (0, 9)!

The total remaining bank balance in the account of Omar after reducing all the debit and adding the paycheck is $761.25.

What do you mean by debit and credit amount?

The money which is paid from an account is called the debit amount and the money which is paid into an account is called the credit amount.

To know the remaining balance of the account, all the debit amount is subtracted from it and all the credit amount is added to it.

The data given in the table is,

Pharmacy       - $15.20-Debited

Rent                - $425.00-Debited

Dinner             - $22.30-Debited

Movie Ticket  - $26.70-Debited

Pay Check     - $1015.50-Credited

Initial Balance- $219.80

The initial balance is $219.80, and a paycheck of $1015.50 is credited to his account. Thus, the total balance in his account without any debit is,

[tex]\rm A_i=1015.50+219.80\\\\A_i=1253.30[/tex]

The total amount debited from their account of Omar is,

[tex]\rm A_d=15.20+425+22.30+26.70\\\\A_d=474.05[/tex]

Thus, the total remaining amount in his account is,

[tex]\rm A= 1253.3-474.05\\\\A=761.25[/tex]

Hence, the total remaining bank balance in the account of Omar after reducing all the debit and adding the paycheck is $761.25.

A theater group made appearances in two cities. The hotel charge before tax in the second city was $1000 lower than in the first. The tax in the first city was 3. 5% and the tax in the second city was 7%. The total hotel tax paid for the two cities was $455. How much was the hotel charger in each city before tax?

Answers

By solving a system of equations we will see that the charge on the first city was $5,000, and on the second city, $4,000.

How much was the hotel charge in each city?

Let's define the variables:

C₁ = charge in the first city.C₂ = charge on the second city.

We know that:

C₂ = C₁ - $1000

And we also know that the total tax is $455, then we can write:

0.035*C₁ + 0.07*C₂ = $455

(this says that the total tax is $455)

So we have a system of equations:

C₂ = C₁ - $1000

0.035*C₁ + 0.07*C₂ = $455

We can replace the first one into the second to get:

0.035*C₁ + 0.07*(C₁ - $1000) = $455

0.105*C₁ - $70 = $455

C₁ = ($455 + $70)/0.105 = $5,000

And:

C₂ = C₁ - $1000 = $5,000 - $1,000 = $4,000

The charge in the first city is $5,000 and in the second city was $4,000.

The probability that Aiko can drive to work without having to stop at a red light is 0.125. The odds against Aiko driving to work without seeing a red light are _[blank]_. What odds best complete the sentence?

Answers

The probability that Aiko drives without seeing a red light is the likelihood of not seeing the red light

The odds against Aiko driving to work without seeing a red light is 7 : 1

How to determine the odd against Aiko?

The probability of not having to stop at a red light is given as:

P(Not Stop) = 0.125

The probability that he would stop at a traffic light is calculated using:

P(Stop) = 1  - 0.125

Evaluate

P(Stop) = 0.875

The odds against Aiko driving to work without seeing a red light is calculated using:

Odd = P(Stop) : P(Not stop)

So, we have:

Odd = 0.875 : 0.125

Odd = 7 : 1

Hence, the odds against Aiko driving to work without seeing a red light is 7 : 1
