How do I solve this?
Snowcat [4.5K]

Answer:

Step-by-step explanation:

First, let's find the area of the triangle. The Area of a triangle can be modeled as

b x h x 1/2; base = 6 and the height equals 8. 6x8=48 then don't forget to divide by 2. 48/2= 24

To find the area of a half-circle, you first need to find the area of the whole circle. Whole circle area equation = r^2 times pi. The diameter is 8 and the radius is 1/2 times the diameter, therefore the radius = 4. 4^2= 16

16pi= approximately 50.24

50.24/2= 25.12

25.12 + 16 = 41.12

The area of the figure is approximately 41.12 ft^2

Hope this helps and please mark me brainliest, it really helps!

If SF = 5x + 2, SK = 27, and KF = 3x - 1,<br> find KF.
kondor19780726 [428]

Answer:

KF = 35

Step-by-step explanation:

Since it's a line with K in the middle, we know that the distance SF is the same as SK + KF.

(Start at S, first go to K, then continue to F. You've traveled the same distance as from S to F.)

SF = SK + KF

Let's put in the values we got.

5x + 2 = 27 + (3x -1)

Opening the parenthesis.

5x + 2 = 27 + 3x - 1

5x + 2 = 26 + 3x

Now let's subtract 3x from both sides.

2x + 2 = 26

Now, subtract 2 from both sides.

2x = 24

If we divide by 2...

x = 12

We know that...

KF = 3x -1

Since x is 12, let's put that in.

KF = 3 * 12 - 1 = 36 - 1 = 35

Answer: KF is 35 !

How is the equation on the top equivalent to 3. Show 5 steps on how you did it.
Sloan [31]

(9)^4 × (27)^3 × (81)^2 / (3)^24 = 3.

Explanation:

  • All the numbers in the numerator i.e. 9, 27, 81 are multiples of 3.
  • 9 = 3 × 3 = 3², 27 = 3 × 3 × 3 = 3³, 81 = 3 × 3 × 3 × 3 = 3^{4}.
  • 9^{4} = (3^2)^4, 27³ = (3^3)^3, 81^2 = (3^4)^2.
  • According to the power rule, (a^x)^y = a^xy.
  • So the given numbers can be written as follows                                                         9^{4} = 3^8, 27³ = 3^9 and 81² = 3^8.
  • According to the product rule, (a^x) × (a^y) = a^xy.
  • So the numerator can be written as                                                                             9^{4} × 27³ × 81² = (3^8) × (3^9) × (3^8) = 3^(8+9+8) = 3^25.
  • So the fraction becomes 3^25 / 3^24 = 3 × 3^24 / 3^24 = 3.
