Answer:

Weight on the moon = 43.60 l b

Step-by-step explanation:

Let the weight of the object on the moon be M.

Let the weight of the object on the earth be E.

M α E

M = kE (where k = constant)

Make k the subject of the formula.

k = M/E

When M = 25.46 l b and E = 149.76 l b

k = 25.46/149.76

k = 0.17

Put k = 0.17 into the equation M = kE

Therefore;

M = 0.17E ( This shows the relationship between M and E)

When E = 256.47 l b

M = 0.17 * 256.47

M = 43.60 l b

Avery deposited $400 in an account that earned 2.47% interest compounded annually. She did not make additional deposits or withd
aev [14]

Answer:

Amount ($451.9), Interest ($51.9)

Step-by-step explanation:

We need to use the formula of A = P(1 + \frac{r}{n})^n*t

A = Total Amount

P = Principle/Deposited money

R = Annual Interest Rate

N = Number of times compounder per year

T = time in years

We have P = $400, r = 2.47%, n = 1 and t = 5 years.

Now lets plug it all in!

A = 400 (1 + \frac{0.0247}{1})^{1*5}

A = 400 * 1.0247^5

A = 400 * 1.129753

A = 451.9

Now we need to find the interest...

We will use A = P + I since A is 451.9 and P = 400

451.9 = 400 + I

I = 451.9 - 400

I = 51.9

Please help, answer and show me the work. Thanks also solve for x
vova2212 [387]

3.  x+100 = 90   alternate interior angles are equal

subtract 100 from each side

x+100 - 100 = 90-100

x = -10


4.  17x+1 = 120    alternate exterior angles are equal

subtract 1 from each side

17x+ 1 -1 = 120 -1

17x = 119

divide each side by 17

17x/17 = 119

x =7
