Answer:

36. m^7

37. x^3 y

38. 6v^5

Step-by-step explanation:

Divide the exponents by the number in the radical sign,

so, If no number is given then divide exponents by 2 eg. question 38

<h3>Explanation </h3>

36. 7√m^49 means m^(49/7) = m^7

37. 3√x^9y^3 means x^(9/3) y^(3/3) = x^3 y

38. √36v^10 means (√36) v^(10/2) = 6v^5 (√36 = 6)

Find the total cost of these items, including tax. Round
solniwko [45]

Answer:

Flashlight ;  = $2.99

Water bottle = $1.50

Toothbrush = $1.29

Compass = $3.29

Step-by-step explanation:

Sales tax = 7%

Item: _____ price

Flashlight ;  = $3.20

Water bottle = $1.61

Toothbrush = $1.38

Compass = $3.52

Total cost = price of item + sales tax

Sales tax = 7%

Total cost = (1 + 7%) * price of item

Total cost = (1 + 0.07) * price of item.

Total cost = 1.07* price

Flashlight = 1.07*1.29 = $3.20

Water bottle = 1.07*1.50 = $1.61

Toothbrush = 1.07*1.29 = $1.38

Compass = 1.07*3.29 = $3.52

a lamp post has half of its length in mud,1 by 3 of its length in water and 3 whole 1by3m above water. find the whole length of
xxMikexx [17]

Answer:

20 m

Step-by-step explanation:

Given:

  • Length in mud = ¹/₂ its length
  • Length in water = ¹/₃ its length
  • Length above water = 3 ¹/₃ m

Let x be the length of the lamp post.

Convert 3 ¹/₃ to an improper fraction:

\sf \implies 3 \frac{1}{3}=\dfrac{3 \times 3+1}{3}=\dfrac{10}{3}

The total length of the lamp post (x) is the sum of the three given lengths:

\implies \sf mud+water+above\: water=x

\sf \implies \dfrac{x}{2}+\dfrac{x}{3}+\dfrac{10}{3}=x

Multiply both sides by 6:

\sf \implies \dfrac{6x}{2}+\dfrac{6x}{3}+\dfrac{6 \cdot 10}{3}=6x

\sf \implies 3x+2x+20=6x

\sf \implies 5x+20=6x

Isolate x:

\sf \implies 20=6x-5x

\implies \sf x=20

Therefore, the whole length of the post is 20 m.
