x beats -------------- 1 min.

Find the percent of change round to the nearest percent original: 50 new: 70
kykrilka [37]

The percent change is 40%

Step-by-step explanation:

The percent change is given by the formula

Percent\ change=\frac{New\ value-Original\ value}{Original} * 100

Here

New value = 70

Original value = 50

Putting the values in the formula

Percent\ change=\frac{70-50}{50}*100\\=\frac{20}{50}*100\\=0.4*100\\=40\%

The percent change is 40%

A country has a total biocapacity of 6.21 ha/person, a biocapacity of grazing land of 0.85 ha/person, and a biocapacity of fores
leonid [27]

Answer:

44.8 %  

Step-by-step explanation:

Let p = the number of people. Then

Total biocapacity     = 6.21p  ha

Grazing biocapacity = 0.85p ha

Forest biocapacity    = <u>2.53p      </u>

Grazing + forest        = 2.78p ha

\text{Percent grazing + forest} = \dfrac{\text{grazing + forest}}{\text{Total}} \times 100 \, \% \\\\= \dfrac{\text{2.78p ha}}{\text{6.21p ha}} \times 100 \, \% = \mathbf{44.8 \,\%}

The order in which you perform operations matters in a numerical expression.
elena-14-01-66 [18.8K]

Answer:

False ( I think )

Step-by-step explanation:

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Pete has the option of borrowing $380 for one week at an APR of 600% or borrowing the $380 for one week with a fee of $45. Which
GarryVolchara [31]
APR = annual percentage rate.

Since Pete is borrowing the money for one week, the APR must be divided into a daily interest rate before we can figure out how much he'll pay for the loan.

There are 365 days in a year. Divide the APR by 365 to find the daily interest rate.

\frac{600}{365} = 1.643

The daily interest rate of the loan will be 1.643%.

The following equation is used to find the total interest payment:

A = P(1+ \frac{r}{365})^{t} - P

A represents the total amount paid in interest. P represents the amount borrowed for the loan. r represents the daily interest rate. t represents the amount of days the loan will last.

Plug in your values into the equation.

P = 380, r = 1.643, t = 7

380(1+ \frac{1.643}{365})^{7} - 380 = 12.136

Rounded to the nearest hundredths value, the total interest paid will be $12.14.

Compare the total amounts paid for both loans.

$12.14 < $45

The better deal is the loan with the 600% APR.
