Answer 1

Answer:

Step-by-step explanation:

4) d = 12 cm; r = 12/2 = 6cm ; h = 5 cm

S.A = 2πr(r + h)

      = 2* 3.14 * 6 * (6 + 5)

     = 2 * 3.14 * 6 *11

    = 414.48 cm²

5) d = 8 cm ; r = 8/2 = 4cm ; h = 7cm

S.A = 2πr(r + h)

      = 2 *3.14 * 4 * (4 + 7)

     = 2 * 3.14 * 4 * 11

    = 276.32 cm²

6) r = 4 cm ; h = 6cm

SA = 2πr(r +h)

     = 2 * 3.14 * 4 * 10

     = 251.2 cm²

7) Area of front and back = [tex]2*\frac{1}{2}*base * height[/tex]

                                         = base  * height

SA = (front and back) + Base + left + right

          = 4* 3 + (8*3) + (8*4) + ( 8*5)

         = 12 + 24 + 32 + 40

         = 108 cm²

8) SA =  (front and back) + Base + left + right

          =  (8 * 6) + (12*6) + (12*8) + (12*10)

         =  48 + 72 + 96 + 120

        = 336 cm²

9) SA =  (front and back) + Base + left + right

          =  (12 *5) + (8*5) + (8*12) +(8*13)

         = 60 + 40 + 96 + 104

          = 300 cm²

If lin runs 21 laps at the same rate, how long does it take her 25.6 minutes How many laps per minute is that? __ laps

Answers

Answer: 0.82 laps per minute

Step-by-step explanation:

Lin is running 21 laps in 25.6 minutes.

To find out her speed in laps per minute, divide the distance she has ran by the time it took her to run it.

= Distance / time

= 21 / 25.6

= 0.82 laps per minute

Which expression is equivalent to 7h^2-252k^2?

D. None of these

Answers

Answer:

c

Step-by-step explanation:

252 = 7 *36

36 = 6 *6 = 6²

a² -b²  = (a + b)(a - b)

7h² - 252k² =  7(h² - 36k²)

                   = 7(h² - [6k]² )

                  = 7(h  +6k)(h - 6k)

Lynn took a taxicab from the office to the airport. She paid $4 per mile plus a $6 flat fee. Her total cost was $66. How many miles was the trip?

Answers

Answer:

12

Step-by-step explanation:

Answer:

15 miles

Step-by-step explanation:

To answer this question, we must break up the question. First, we know Lynn paid a total of $66 for the trip. She had to pay $4 per mile, and the flat fee was $6, meaning that no matter how many miles they rode, she had to pay an extra $6 on top of that. So, we can subtract the total cost by the flat fee:

66 - 6 = 60

Then, we divide that number by the amount it costs to ride each mile, which is 4:

60 / 4 = 15

So, Lynn's trip was 15 miles

I need to find the measure of angle A

Answers

Answer:

∠ A = 30°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

90 + x + 67 + x + 37 = 180, that is

2x + 194 = 180 ( subtract 194 from both sides )

2x = - 14 ( divide both sides by 2 )

x = - 7

Then

∠ A = x + 37 = - 7 + 37 = 30°

0.24 as a percent. i already know that its 24% but can you show me an explanation

Answers

Explanation:

So any decimal number is the same as a percentage but take off ONE zero in front of it

So with 0.24 for example, you take off the zero in front and since there are no zeros for the decimal point to be behind, there is no need for the decimal point now, so the percentage is 24%

Russom deposits $500 into a compound interest account. The interest rate for the
account is 3.25%. Determine the account balance after 5 years.

Answers

Answer:

$581.25

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.25%/100 = 0.0325 per year,

then, solving our equation

I = 500 × 0.0325 × 5 = 81.25

I = $ 81.25

The simple interest accumulated

on a principal of $ 500.00

at a rate of 3.25% per year

for 5 years is $ 81.25.

The value of x is: x = 35.57.

Here, we have,

given that,

from the given diagram, we get,

it is a right angle triangle,

base = x

hypotenuse = 37

and angle = 16°

now, we know that,

cos θ = adjacent / hypotenuse

so, we get,

cos 16° = x/37

The value of cos 16° is equal to the x-coordinate (0.9613).

∴ cos 16° = 0.9613.

=> 0.9613 = x/37

=> x = 35.57

Hence, The value of x is: x = 35.57.

System of Equations:

8s + 7c = 211

4s + 6c = 138

I used the elimination method and multiplied the second equation by -2

-8s - 12c = -276

add the above to the first equation and get

-5c = -65

c = 13

now find s

8s + 7(13) = 211

8s + 91 = 211

8s = 120

s = 15
