When you buy the bond the exchange rate is $1.50 = pound1. You pay pound45 ($67.50) for the British bond. You sell the bond

natka813 [3]

Answer:

The gain is of $17.50

Step-by-step explanation:

When you buy the bond the exchange rate is $1.50 = £1.

You pay £45 = $1.50\times45$ =$67.50 for the British bond.

No, you sell the bond for £50 and the exchange rate is $1.70 = £1.

So, you earned $50\times1.70=85$ dollars

Your gain is $85-67.50$ = $17.50

Use the coordinate plane to plot the points (6, 0) and (0, 5). Which statement is true? (0, 5) is located on the x-axis. (0, 5)

m_a_m_a [10]

Answer:

(6, 0) is located on the x-axis

Explanation:

For a point to be on the x-axis, its y-value must equal 0. (6, 0) has an x-value of 6 and a y-value of 0.

"(0, 5) is located at the origin" is not true because the origin is at (0, 0).

"(0, 5) is located on the x-axis" is not true because its y-value is 5, not 0.

"(6, 0) is located at the origin" is not true because the origin is at (0, 0).
