You need to find the width of the stream. You cannot measure the width directly, so you draw a diagram showing lengths that you

can measure. Your diagram contains two similar triangles, one in the stream and one on land. Use the diagram to find the width of the stream.

I believe it is a) 22.4 feet.  I looked at the comparison between the 6 feet and the width of the lake and a) seemed to make the most sense.

You are given that the diagram contains two similar triangles.

Two similar triangles have proportional sizes of corresponding sides.

Then the ratio between smaller legs is the same as the ratio between greater legs:

\dfrac{x}{6}= \dfrac{28}{7.5},\\ \\x=\dfrac{28\cdot 6}{7.5}=22.4\ ft.

Answer: correct choice is A.

debt payments of $800 due now and $1400 due in 5 months are to be repaid by a payment of $1000 in 3 months and a final payment i
loris [4]

Answer:

$1,304.70

Step-by-step explanation:

If interest 6% annually, monthly is 0.5%.

The debt in 5 months will be 800 plus compounded interest for 5 months plus new due debt

800(1.005)^5+1400=2220.201

In 3 more months the debt will be 2220.201 plus compounded interest for 3 months minus payment

2220.201(1.005)^3-1000=1253.67

After 8 months the debt would be 1253.67 plus compounded interest for 8 months

2220.201(1.005)^3=1304.70

Then the size of the final payment would be $1,304.70
