Okay. I'll use a formula that my math teacher taught me.

3400(1-0.07)^15
3400(0.93)^15
3400(0.33670086205)
1144.78293098 ( which rounds to about 1145 square km )

Answer:

1144.78 Km^2

Step-by-step explanation:

If the forest covers an area of  3400 km^2 and it decreased by 7%, the new area covered after a year will be equal to 3400 less the product of 3400 and 7%

= 3400 - 7% * 3400

= 3400 (1 - 0.07)

After the second year, the area becomes

= 3400 (1 - 0.07) - 7% * 3400 (1 - 0.07)

= 3400 (1 - 0.07)(1 - 0.07)

= 3400 (1 - 0.07)²

Following this pattern, the area after 15 years

= 3400 (1 - 0.07)^15

= 1144.782931  km^2

Dominic is signing up for a gym membership with a one-time fee to join and then a monthly fee to remain a member. The monthly fe
insens350 [35]

The equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t

<h3>Equation</h3>

There are three basic types of equation in mathematics. Namely:

  • Linear equations
  • Quadratic equations
  • Simultaneous equations

  • Monthly fee = $50
  • One-time joining fee = $150
  • Total cost = C
  • Number of months = t

C = 150 + 50t

Therefore, the equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t

(-6,20) \\&#10;x=-6 \\ y=20 \\ \Downarrow \\&#10;20 \stackrel{?}{=} (-6)^2+2 \times (-6)-4 \\&#10;20 \stackrel{?}{=} 36-12-4 \\&#10;20 \stackrel{?}{=} 20 \\&#10;20 = 20 \\&#10;\hbox{the point is on the graph}

(-4,4) \\&#10;x=-4 \\ y=4 \\ \Downarrow \\&#10;4 \stackrel{?}{=} (-4)^2+2 \times (-4)-4 \\&#10;4 \stackrel{?}{=} 16-8-4 \\&#10;4 \stackrel{?}{=} 4 \\&#10;4 = 4 \\&#10;\hbox{the point is on the graph}

Nancy is making lemonade for her birthday party. She made 6 batches. Each batch of lemonade uses 24 fluid ounces of lemon juice
Goryan [66]

Answer:

Step-by-step explanation:

1 Us pint = 16 Us fluid ounces

It means that 8 pints of water would be

8 × 16 = 128 fluid ounces

Each batch of lemonade uses 24 fluid ounces of lemon juice and 8 pints of water. The total number of fluid ounces in each batch is

128 + 24 = 152 fluid ounces

Also,

1 fluid ounce = 0.125 Us cups

Therefore, the number of cups made is

152 × 0.125 = 19 cups

If each serving is 1 cup, then the number of servings that she made from each batch of lemonade is 19

servings. The number of batches made is 6. Therefore, the number of servings made altogether is

6 × 19 = 114

If her brother came and spilled half of it on the floor, then the number of servings that she have left after that for her party is

114/2 = 57 servings
