What i did is used Pythagorean theorem and did A2+B2=C2

so 336squared+45squared=Csquared

112896+2025=114921
C=114921
the square root of C=339
so diagonally from her house to the point of 45south and 336east is 339meters  <span />

Candice deposited $3,587.39 into a savings account with an interest rate of 4.2% compounded twice a year. About how long will it
Ratling [72]
Time taken for the amount deposited to grow to $5000 will be found as follows:
A=P(1+r/100*n)^nt
where:
A=amount
P=principle
r=rate
n=number of terms
t=time
thus plugging in our values we have:
5000=3587.39=(1+4.2/200)^2t
solving for t we have:
1.393771=1.021^2t
2t=ln1.393771/ln1.021
2t=16.111
t=8.055685 years~8 years

Mary drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 7 hours. When Mary drove h
ELEN [110]
There are two separate equations for this question that use the same variable.

Mary took 7 hours to complete a trip with traffic. This would use the following expression:

7x

Mary took 4 hours to complete the same trip without traffic. The average rate of speed was 27 mph faster than the trip with traffic. This uses the following expression:

4(x+27)

Both trips had the same distance. From the information provided, we can set up the following equation:

7x = 4(x+27)

x represents the average rate of speed on both trips.

Distribute 4 to each term in parentheses:

4 \times x = 4x
4 \times 27 = 108

7x = 4x + 108

Subtract 4x from both sides:

3x = 108

Divide both sides by 3 to get x by itself:

x = 36

The average speed for the slower trip is 36 mph.

We can plug this value into the first equation:

7(36) = 7 \times 36 = 252

Mary lives 252 miles away from the mountains.

Simplify 5/96 - 7/54
Jobisdone [24]

Answer:

The answer is

<h2>- \frac{67}{864}</h2>

Step-by-step explanation:

<h3>\frac{5}{96}  -  \frac{7}{54}</h3>

To solve first find the LCM of the denominators

That's

The LCM of 96 and 54 is 864

So we have

<h3>\frac{5}{96}  -  \frac{7}{54}  =  \frac{5(9)  - 7(16)}{864}</h3><h3>=  \frac{45 - 112}{864}</h3><h3 />

We have the final answer as

<h3>=  -  \frac{67}{112}</h3>

Hope this helps you
