On the Mercator map, the continental U.S. looks much larger than Australia. In reality, the continental U.S. is only about 200 miles wider than Australia. Describe how you would change the map to reflect this fact.

Answers

Due to the fact that the Earth has the shape of a geoid, and if you look at it from space, it will seem that the continents that are on two sides of the earth are smaller than those that are in the middle, and a flat map is a cut of one of the sides of the geoid. That's why there is such an optical illusion.

What is Distance Formula?

If there are two point A(x, y) and B( a, b) then distance between a and B is

d = √(a- x)² + (b -y)²

Given:

The coordinates are:

A(0, 2), B(-1, -3), C(5, -4) and D(6, 1)

Then, AB = √(-1- 0)² + (-3 +2)²

AB= √1 + 1

AB= √2

BC= √(5+1)² + (-4 + 3)²

BC= √36 + 1

BC= √37

CD= √(6-5)² + (1+4)²

CD= √1 + 25

CD= √26

DA= √(6-0)² + (1-2)²

DA= √36+ 1

DA= √37

No, the given Quadrilateral is not a rectangle because opposites sides measurement is not equal.

Answers

Answer:

No, Trey is not correct.

Step-by-step explanation:

3^4 = 3 • 3 • 3 • 3 = 81

4^3 = 4 • 4 • 4 = 64

81 is not equal to 64, so 3^4 is not equal to 4^3.

So basically this problem is asking if exponents can use the commutative property. The commutative property basically tells us that in addition and multiplication numbers can be switched to make it easier for us to solve. That doesn’t go for exponents though. 3 to the 4th power would be 81 and 4 to the 3rd power would be 64. So basically you can only use the commutative property in addition or multiplication problems. Not exponents, subtraction, or division. I hope I explained it well.

For Home economics class, Sandra has 5 cups of flour. She made 3 batches of cookies that each used 1.5 cups of flour. Write and solve an expression to find the amount of flour Sandra has left after making the 3 batches?

Answers

Answer:   .5 cups of flour

Step-by-step explanation:   So, Sandra made 3 batches of cookies that each used 1.5 cups of flour. The key word is “each”. So, 3 x 1.5 = 4.5. Sandra uses 4.5 cups of flour. She has 5 cups of flour. 5 - 4.5 = .5

Answer:

Sandra has 0.5 cups of flour left after making the 3 batches.

Step-by-step explanation:

1 batch = 1.5 cup

3 batch = ?

1.5*3 = 4.5

1.5+1.5+1.5 = 3+1.5 = 4.5

5-4.5 = 0.5

Jalissa's mom purchased coffee from the local coffee shop. The first cup of coffee was $4.15. Each refill is $1.25. She also decided to get a bagel for $3.50. If Jalissa's mom had 2 refills and a $0.50 discount as part of the rewards program, how much did she spend at the coffee shop?

Answers

Answer is $9.65
1.25 x 2 = 2.50
4.15 + 3.50 = 7.65
7.65 + 2.50 = 10.15
10.15 - 0.50 = 9.65

Answer:

$9.65

Step-by-step explanation:

1.25 * 2 = 2.5 + 4.15 + 3.5 - 0.5 = $9.65
