Answer:

(a) 2.27 lb/$

(b) 0.10 mi/min

Step-by-step explanation:

Pounds per dollar is found by dividing pounds by dollars:

(25 lb)/($11.00) ≈ 2.272727... lb/dollar

The digit in the thousandths place is less than 5, so that digit and all digits to its right are dropped when rounding to hundredths.

2.27 pounds per dollar

Speed in miles per minute is found by dividing miles by minutes:

(6 mi)/(58 min) ≈ 0.103448... mi/min

Rounding to hundredths is done the same way as above.

0.10 miles per minute

_____

If the digit to the right of the place you're rounding to is 5 or more, then 1 is added in the place you're rounding to when digits to its right are dropped.

Samantha has $1,290 in a savings account that pays 4% simple interest. How much interest will she earn in 9 months? How much wil

Masja [62]

Given:

Principal = $1290

Rate of simple interest = 4%

Time = 9 months

To find:

The interest and total saving in the account altogether.

Solution:

The formula for simple interest is

$I=\dfrac{P\times r\times t}{100}$ ...(i)

where, P is principal, r is rate of interest and t is time in years.

We know that,

$12\ months=1\ year$

$1\ month=\dfrac{1}{12}\ year$

$9\ months=\dfrac{9}{12}\ year$

$9\ months=0.75\ year$

Putting P=1290, r=4 and t=0.75 in (i), we get

$I=\dfrac{1290\times 4\times 0.75}{100}$

$I=\dfrac{3870}{100}$

$I=38.70$

So, the simple interest is $38.70.

Total savings is

$1290+38.70=1328.70$

Therefore, the total amount in the account altogether is $1328.70.

Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> 4e2x - 3 - 5 = 0

Deffense [45]

Answer:

Value of x will be 0.1515

Step-by-step explanation:

We have given the equation $4e^{2x}-3-5=0$

We have top fond the value of x using exponent and logarithmic property

So $4e^{2x}-3-5=0$

$4e^{2x}-8=0$

$4e^{2x}=8$

$e^{2x}=2$

Taking log both side

$lne^{2x}=ln2$

$2x=0.3010$

x = 0.1515
