Answer: A = 100 square unit

Step-by-step explanation:

The formula for calculating the area of a square when the diagonal is given is :

Area = d^{2} / 2

That is :

A = \frac{(10\sqrt{2})^{2}}{2}

A = \frac{100(2)}{2}

A = 100 square unit

Katherine invested $86,000 in an account paying an interest rate of 52%
earnstyle [38]

Answer: $4,331‬

Step-by-step explanation:

I will assume that the question meant 5.2% not 52% as this is quite excessive.

Katherine after 13 years.

Convert the variables;

n = 13 years = 13 * 365 = ‭4,745‬ days

r = 5.2% = 5.2/365 = 5.2/365%

Future value = P * ( 1 + r)^n

= 86,000 * (1 + 5.2/365%)⁴⁷⁴⁵

= $169,068

Michael after 13 years;

If compounded continuously, the formula is;

Future value = Pe^rt

= 86,000 * e⁰.⁰⁵ ˣ ¹³

= $164,737

Difference = 169,068 - 164,737

= $4,331‬

The ratio of Mike buying fish to Millie buying fish was 8 to 2. If in total they bought 150 pounds of fish. How many pounds did
Lady bird [3.3K]

Answer: Mike bought 120 pounds of fish and Millie bought 30 pounds  of fish.

Step-by-step explanation:

If the ratio is 8 to 2 then  8/10 will be the probability of Mike buying fist and 2/10 will be the probability of Millie buying fish.

Now multiply each fraction by the total number of pounds to find how many pounds each bought.

8/10 * 150 = 1200/10 = 120

2/10 * 150 = 300/10 = 30  

In this case, Mike bought 120 pounds of fish and Millie bought 30 pounds  of fish.
