Due to global warming, over a 20-year period, many birds have extended the northern margins of
their ranges by an average of about 12 miles. Assuming global warming continues at the same
rate, by how many miles will they have extended their range in another 10 years?

Answers

I’m pretty sure it’s 16 miles.
12 divided by 2 is 6
So in another 10 years, they would have extended their range by 6 more miles in 10 years.
So 30 years would be 16 miles.

Amil took $65.00 to go shopping, and he bought 2 pair of jeans for $27.00 each. How much change will he have? Choose the expression that is a correct translation of the problem.
(2 x 27) - 65
65 – (2 x 27)
65 – (2 + 27)
65 – 2 + 27

Answers

Answer:

B) 65 – (2 x 27)

Step-by-step explanation:

65 is you total, 2 is the amount of jeans and 27 is the individual price of the jeans.

Since you want to know how much is left over, you subtract how much you spent which would be, in this case, the jeans.

You bought 2 jeans, each for 27 dollars so you multiply the two to see how much for both jeans.

Subtract that from the total.

Hope this helps! (^-^)

Answer:

65-(2 x27)

Step-by-step explanation:

You already know that Amil has 65$ so that's the first part.

And then it tells you that he bought 2 pairs of jeans and the price.

So if u multiply how many jeans he got times the price that tells you how much it cost. So it cost 54$

Last but not least you subtract 54$(the price) from 65$(how much money he had) to get the amount of change left over.

Today, everything at a store is on sale. The store offers a 20% discount.

a) The regular price of a T-shirt is $18. What is the discount price?

b) If the regular price of an item is dollars, what is the discount price in dollars? Write an expression.

c) The discount price of a hat is $18. What is the regular price?

Answers

Answer:

a. $14.4

b. $18 • .2 = $3.6

c. $21.6

Step-by-step explanation:

a. Make the 20% a decimal, and multiply by the regular price. Then, subtract that and you'll get the discounted price.

18 • .2 = 3.6

18-3.6 = $14.4

b. Use the equation multiplying the 20% as a fraction here.

c. Multiply $18 by .2 (the discount). Then, add that to the discount price ($18).

18 • .2 = 3.6

3.6 + 18 = $21.6

It helped explain some observations that Newton's idea didn't account for. It also opened our minds to amazing new possibilities. For example, taking his cue from Einstein's idea that space bends, scientist Karl Schwarzschild began to think about what would happen if a place in space were extremely distorted. His answer: light would follow the hyper-bent space, never to turn away from it. This was the first prediction of a black hole. At first, some scientists (including Einstein!) rejected Schwarzschild's ideas. Others were intrigued and began searching the skies for real black holes. Just decades later, they found the first of them. It just goes to show: sometimes, as Einstein himself once said, "Imagination is more important than knowledge."
