How many years will it take for the area of the glacier to decrease to 15 square kilometers

Mathematics
1 answer:
atroni [7]3 years ago
5 0

Answer:

  20ln(3)

Step-by-step explanation:

Put 15 for A and solve for t.

  15 = 45e^(-.05t)

  15/45 = 1/3 = e^(-.05t) . . . . divide by 45

  ln(1/3) = -.05t . . . . . . . . . . . take natural logs

  20ln(3) = t . . . . . . . . . . . . . . multiply by 20, simplify

It will take 20·ln(3) years for the area to decrease to 15 km^2.

Count by five from 135 to 175 .write these numbers and describe the pattern
melomori [17]
<span>Count by five from 135 to 175 means you will increase the number by 5 each time.
The pattern will be as follows:
135
135 + 5 = 140
140 + 5 = 145
</span>145 + 5 = 150
150 + 5 = 155
155 + 5 = 160
160 + 5 = 165
165 + 5 = 170
170 + 5 = 175

The pattern is n+5 where n is the previous number in the pattern.

Mr Teo wants to buy an oven. Which shop sells the oven at a lower price? Show your working clearly.​
Oliga [24]

Answer:

Shop B

Step-by-step explanation:

Hi there!

To solve this question, we can find the new prices of each oven and identify which one is cheaper.

<u>Shop A</u>

Usual price: $190

Discount: 15%

First, we must subtract the discount percent from 100:

100 - 15 = 85

Therefore, the new price of the product will be 85% of the original price. Find 85% of $190:

190 × 0.85

Therefore, the new price is $161.50.

<u>Shop B</u>

Usual price: $200

Discount: 20%

Again, subtract 20 from 100:

100 - 20 = 80

This means that the new price of the oven is 80% of the original price:

200 × 0.8 = 160

Therefore, the new price is $160.

Because a $160 oven is cheaper than a $161.50 oven, Shop B sells the oven at a lower price.

I hope this helps!
