first put them into standared form.

33000+770000

then add.

803000

then put back into scientific notation.

8.03x10^5

Answer:

8.03 x 10^6

(3.3 x 10^4) + (7.7 x 10^5)= 803000 and move the decimals 6 places to get it behind the 8

Answer:

p*15%

p*15%*6%

Step-by-step explanation:

Answer:

Part A: 0.85p

Part B: 0.901p

Step-by-step explanation:

The phone's original price: 100%

The phone's sale price: 15% off the original price

p = original price of the phone

Part A:

100% - 15% = 85%

85% = 0.85

The expression: 0.85p

Part B:

6% = 0.06

0.06 * 0.85p ==> (the sales tax * the discounted price of the phone)

0.051p

0.85p + 0.051p

0.901p

Hope this helps!

Answer: 84

Step-by-step explanation:

We have, 25% × x = 21
or,

25
--------   × x = 21
100  

Multiplying both sides by 100 and dividing both sides by 25,

we have x = 21 ×

100

25

x = 84

If you are using a calculator, simply enter 21×100÷25, which will give you the answer.

Answer:you gotta divide

Step-by-step explanation:

Answer:

1. 333.2 N

2. 19

Step-by-step explanation:

1. So first lets write what we have :

Mass= 34g

Acceleration=9.8m/s^2

Force= x

Formula: Force= Mass * Acceleration

Force= 34 * 9.8

Force = 333.2N

So the force is equal to mass * acceleration

The answer then becomes 333.2N

2. Mass = 57gm

Volume= 3cm^3

Density= x

Density = mass / volume

The density is equal to the mass divided by the vilume thus 57 / 3 = 19

Density = 19

Answer:

16 = 2x

Step-by-step explanation:

The pattern for a direct variation equation is y = kx

y is the "output" or result

k is the "constant" a number that doesn't change in the equation.

x is the "unknown" variable that makes the output of the equation true when found.

Here x=8

16 = 2(8)

Answer:

16 = 2x

Answer:

-66/15

Step-by-step explanation:

Convert all of them to improper fractions:

26/3 - 19/5 + 139/15

Using the rule of BODMAS;

We will add first before we subtract.

26/3 - (19/5 + 139/15)

L.C.M of 5 and 15 is 15

26/3 - (13×19)+(1×139)/15

{26/3 - 196/15}

Now we will subtract

LCM of 3 and 5 is 15

(5×26) - (1×96)/15

=130 - 96/15 = -66/15.

(150, 7) is wrong because its at the 6 hour line, not 7

(12.5, 1) doesn't even exist!

(75, 3) is at the 75 mile line and 3 hour line, so it would be the answer

Step-by-step explanation:

Answer:

 56 % of original price or 44 % off

Step-by-step explanation:

x times 0.7 times 0.8 = .56x    

The total percent discount is 42.88%.

A ratio or value that may be stated as a fraction of 100 is called a percentage. Moreover, it is indicated by the symbol "%."

Let's assume that the original price of an item is 100 dollars.

After the first discount of 32%, the price of the item becomes:

100 - (32% of 100) = 68 dollars

After the second discount of 16%, the price of the item becomes:

68 - (16% of 68) = 57.12 dollars

So the final discount on the original price is:

100 - 57.12 = 42.88 dollars

To find the total percent discount, we need to calculate what percentage 42.88 dollars is of the original price of 100 dollars:

(42.88 / 100) x 100% = 42.88%

Therefore, the total discount is 42.88%.
