Answer:

\frac{1cm}{4 meters}

Step-by-step explanation:

To find the scale, we write a ratio of \frac{map}{real world} and simplify.

Assuming the 40 meter side corresponds to 10 cm, we know \frac{map}{real world}=\frac{10cm}{40 meters}. We simplify to \frac{1cm}{4 meters}

Answer:

XQ = 12

Step-by-step explanation:

In this question it asks for XQ instead of x, but you need to find x first.

1. Find x.

XQ is half of MQ so this statement is true: 3x - 3 = 2(2x - 6)

Solve for x.

3x - 3 = 2(2x - 6)

Distribute 2.

3x - 3 = 4x - 12

Isolate x.

3x = 4x - 9

-x = -9

Divide -1 out.

x = 9

Now solve for XQ, which the equation is given.

XQ = 2(9) - 6

XQ = 18 - 6

XQ = 12

PLS HELP ASAP!! WILL MARK BRAINLYIST
Murljashka [212]

Answer:

After 5 years, savings account = $241.00

After 8 years, savings account = $269.53

Step-by-step explanation:

If the savings account increases by 3.8% per year, this means it will be 103.8% of the previous year's value since 100% + 3.8% = 103.8%

103.8% in decimal form = 103.8/100 = 1.038

Therefore, the exponential function is:

y = 200 \cdot 1.038^x, where x is the number of years

So when x=5,  

y = 200 \cdot 1.038^5=240.99984...

After 5 years, savings account = $241.00

After 8 years, savings account = $269.53
