Sara has $150 in her savings account. The amount in her account increases by %6 every year. If she does not put more money into

strojnjashka [21]

Answer:

$159

Step-by-step explanation:

we know that

The equation of a exponential growth function is equal to

$y=a(1+r)^x$

where

y is the balance in the saving account

x is the number of years

a is the initial amount

r is the percent rate of change

we have

$a=\$150\\r=6\%=6/100=0.06$

substitute

$y=150(1+0.06)^x$

$y=150(1.06)^x$

For x= 1 year

substitute

$y=150(1.06)^1=\$159$

Dale says the ratios 3:5 and 2:10 are equivalent. Is He correct? Explain

Mnenie [13.5K]

Answer:

No, Dale Isn't correct because 3:5 is greater than 2:10

Step-by-step explanation:

3:5 and 2:10 is the same as in $\frac{3}{5}$ and $\frac{2}{10}$

First Find the least common denominator or LCM of the two denominators:

LCM of 5 and 10 is 10

Next, find the equivalent fraction of both fractional numbers with denominator 10

For the 1st fraction, since 5 × 2 = 10,

$\frac{3}{5} =\frac{3*2}{5*2} =\frac{6}{10}$

Likewise, for the 2nd fraction, since 10 × 1 = 10,

$\frac{2}{10} =\frac{2*1}{10*1} =\frac{2}{10}$

Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

$\frac{6}{10} >\frac{2}{10} Or\frac{3}{5} >\frac{2}{10}$

Hence, $\frac{3}{5}$ is <u>Greater than </u> $\frac{2}{10}$

Hence, 3:5 is <u>Greater than </u>2:10
