Write and solve a proportion to complete the statement. Round to the nearest hundredth if necessary.
wariber [46]

Answer:

Step-by-step explanation:

<h3>Convert kilometer to miles:</h3>

1 km = 0.62 mi

So, to convert 6 km to mi, multiply 6 by 0.62.

6km = 6* 0.62

        = 3.72 mi

<h3>Convert liter to gallon:</h3>

1 L = 0.26 gal

To convert 2.5 L to gallon, multiply 2.5 by 0.26.

2.5 L = 2.5 * 0.26

         = 0.65 gal

<h3>Convert pound to kilogram:</h3>

1 lb = 0.45 Kg

To convert 90 lb to Kg, multiply 90 by 0.45.

90 lb = 90 *0.45

        = 40.5 Kg

What is the area of the figure to the nearest hundredth renter the answer in the box 2yd 4yd
Norma-Jean [14]

Answer:

9.57 yd squared

Step-by-step explanation:

we can divide this figure into two shapes:  a rectangle and a semi-circle

since we know the length and width of the rectangle, all we ahve to do is multiply them together to find the area: <u>8 yd squared</u>

for the semi-circle, we know the area is \frac{\\\pi r^2}{2\\}

raduis is half the diameter so 1 yd

\frac{3.14(1)^2}{2}

\frac{3.14}{2}<u />

<u>1.57 yd squared</u>

lastly, add the area of the two figures together 8+1.57

Find the exponential function that satisfies the given conditions: Initial value = 64, decreasing at a rate of 0.5% per week
mrs_skeptik [129]

Answer:

Step-by-step explanation:

An exponential function is of the form

y=ab^x

where a is the initial value and b is the growth/decay rate.  Our initial value is 64.  That's easy to plug in.  It goes in for a.  So the first choice is out.  Considering b now...

If the rate is decreasing at .5% per week, this means it still retains a rate of

100% - .5% = 99.5%

which is .995 in decimal form.

b is a rate of decay when it is greater than 0 but less than 1; b is a growth rate when it is greater than 1.   .995 is less than 1 so it is a rate of decay.  The exponential function is, in terms of t,

f(t) = 64(.995)^t
