2. Solve this equation for x:<br> 0.17k - 0.43 = 0.25k + 0.05
stepan [7]

Answer:

k = 6

Step-by-step explanation:

im guessing you meant solve for k

0.17k - 0.43 = 0.25k + 0.05

-0.17k             -0.17k

-0.43 = 0.08k + 0.05

-0.05               -0.05

-0.48 = 0.08k

divide both sides of the equal sign by 0.08

6 = k

your planning to build a boat. you have a sample board of wood that you want to use . the board has an area of 1/3 ft squared an
frosja888 [35]
Given:
Area of sample board: 1/3 square ft.
Weight of sample board: 1/5 lbs

We need to get the weight of the whole square foot.

1/3 square foot is only a part of the whole square foot. Its corresponding weight is 1/5 pounds. We need to divide the area by its corresponding weight to get the total weight per square foot.

1/3 ÷ 1/5 

Rules of dividing fractions:
1st fraction: 1/3 ; 2nd fraction: 1/5

1) Get the reciprocal of the 2nd fraction. 1/5 ⇒ 5/1

2) Multiply 1st fraction to the reciprocal of the 2nd fraction
1/3 * 5/1 = 5/3

3) Simplify fraction.
5/3 is an improper fraction. To simplify it, it needs to become a mixed fraction.

5/3 = 1 2/3 pounds.

A teacher wants to award prizes for 1st, 2nd, 3rd, 4th and 5th in the class of
antoniya [11.8K]

Answer:

2,052,086,400.

Step-by-step explanation:

Permutation

Pr = n! / (n-r)!

30P5 = 30! / (30-5)

30P5 = 30x29x28x27x26x25! / 25!

(Just cancel the 25! on the numerator and denominator for easier solving.)

30P5 = 30x29x28x27x26

30P5 = 17,100,720.It is not the final answer because we can still arrange the 5 winners.

5! = 5×4×3×2×1 = 12017,100,720 × 120 = 2,052,086,400
