Use the order of operations to simplify 5*3 to the second power-15/5

ASHA 777 [7]

Assuming the question reads:

$5 \cdot 3^2 - 15 \div 5$

The order of operations is as follows:

Parentheses

Exponents

Multiplication/Division

Addition/Subtraction

There are no parentheses in the equation.

There is an exponent in the equation. Solve this term first:

$3^2 = 9$

The equation should now read:

$5 \cdot 9 - 15 \div 5$

There are two multiplication/division operations in the equation. Solve them individually:

$5 \cdot 9 = 45$

$15 \div 5 = 3$

The equation should now read:

$45 - 3$

There is one subtraction operation. Solve this term for your answer:

$45 - 3 = \boxed{42}$

Lilly is a pizza driver. Lilly has to make 4 deliveries.

Veronika [31]

Answer:

23 min 30 sec

Step-by-step explanation:

First, you add 35 + 14 + 18 + 27 which is 94.
Next, you divide 94 by the number of deliveries there were. Which is 4.
94/4 = 23.5.
So your answer would be 23 minutes and 30 seconds.

A nature museum has 2008 specimens of early birds, some with 222 wings and some with 444 wings. The specimens have a total of 40

ludmilkaskok [199]

Let's assume

number of birds with 2 wings is x

number of birds with 4 wings is y

A nature museum has 2008 specimens of early birds

so,

$x+y=2008$

Total of wings of 2 wings bird =2x

Total of wings of 4 wings bird =4y

The specimens have a total of 4384 wings

so, we get

$2x+4y=4384$

we can divide both sides by 2

$x+2y=2192$

so, we get system of equations as

$x+y=2008$

$x+2y=2192$

we can solve for x and y

We can subtract both equations

$2008-y+2y=2192$

$y=184$

$x=2008-184$

$x=1824$

$y=184,\:x=1824$

so,

number of birds with 2 wings is 1824

number of birds with 4 wings is 184.............Answer

5. Choose the fragment which best completes the following sentence. Finance charges on a credit card Include (2 points)

lisabon 2012 [21]

Finance charges on a credit card Include "all of the above".

Option: D

Explanation:

Practically, a finance charge is any expense shown in the borrowing money costs, such as accrued interest and loan fees, including transaction fees. Finance charges are usually synonymous with "interest charges" even though they may contain late fees or other costs in some situations.

With credit cards, the interest that has accrued over the amount one owe throughout that particular billing cycle is an individual's finance fee. For every day of the month, the regular balance approach sums up an individual's financing fee. One need to know the precise credit card balance every day of the billing cycle to do that estimate correctly.
