1 answer:
natali 33 [55]3 years ago
3 0

Answer: 1/3 = 33.3% or 33 ⅓%

1/9 = 11.1%

2/9 = 22.2%

8/9 = 88.9%

Step-by-step explanation:

Divide the numerator by the denominator. Multiply the quotient by 100 to change the decimal to a percentage.

All of these are repeating decimals, so it may be required to keep at least one decimal place in the percentage, depending on how precise the calculation must be.

Answer:

$2.00

Step-by-step explanation:

You can form an equation with these statements, x being the price of cheese pizza and y being the price of pepperoni. Making the equation,

3x+4y=18

3x+2y=12

Solving the equation,

3x+4y=18

6x+4y=24

-3x=-6

x=2

y=3

Solving another way,

2y=6

y=3

x=2

Therefore, the answer is $2.00

Which is the correct way to write 602, 200,000,000,000,000,000,000 in scientific notation?
scoundrel [369]
Scientific notation is
n times 10^x
where 1≤n<10 and x is the number of places the decimal place moved (if it moved to the right, x is negative, if it moved to the left, x is positive)


602, 200,000,000,000,000,000,000.0
we see we need to move decimal to the left 23 spaces to here
6.022 times 10^23

answer is 6.022*10^{23}

Find the area of the shape above ?
Juli2301 [7.4K]

Area of triangle = <em>A(t) </em>= 1/2(base x height)

Area of square = <em>A(s) = </em>base x height

<em>A(s) </em>= 2 x 2 = 4

<em>2(A(s))</em> = 2(1/2(2)(2) = 2(1/2(4)) = 2(2) = 4

Add the two areas together

4 + 4 = 8

8 units² is your answer

I need help on this question hurry!!
Natasha_Volkova [10]

Answer:

(0.4,1)

Step-by-step explanation:

I hope that this is for homework and not a quiz or test.

Since we already know the value of y which is 1, we can substitute it into the equation above it.

-5x+3=1

-5x=-2

x=2/5=0.4

So in (x,y) format (0.4,1)
