30% off
theh shirt is 22.40 after discount
original=100%
 original-discount=22.40
100-30=70%
22.40=70%
percent means parts out of 100
22.40=70/100 of original
multiply both sides by 100/70 to clear fraction
2240/70=original
32=original


original=$32.00

The price of the shirt is $22.40.
Since it is 30% off, you would need to add back on the 30%
22.40*100% is 22.40, So you would do 22.40*130% to bring back the thirty.
The answer is $29.12
To check the answer, you can do 29.12*70% because 100-30=70

A bowl of fruit is on the table. It contains 5 apples, 2 oranges, and 2 bananas. Christian and Aaron come home from school and r
Sholpan [36]

The probability that both grab oranges would be = \frac{1}{36}

Step-by-step explanation:

Given,

A bowl contains,

Apples = a = 5

Oranges = o = 2

bananas = b = 2

Total fruits in bowl = x = a + o + b = 5 + 2 + 2 = 9

Now, Christian and Aaron come home from school and randomly grab one fruit each.

The probability of first selecting orange would be = \frac{o}{b} = \frac{2}{9}

Now, the oranges left would be 2 - 1 = 1

and total fruits would be = 9 - 1 = 8

Hence, the probability of selecting second orange would be = \frac{1}{8}

Therefore, the probability that both grab oranges would be = \frac{1}{8} * \frac{2}{9} = \frac{1}{36}

g100num [7]
So you are using Volume...

V=1/3(pi)r^2h
as you go thu this equation

15 x 15 =225
12 x12= 144
225-144= 81
81/9=9

which your piece would be 1/3 pi r^2h answer is 1356.48
and you round it to the nearest tenth. So

myrzilka [38]

Answer:

Shawn

Step-by-step explanation:

We can find the amount of vehicles sold in one week by dividing the total vehicles sold by the number of weeks

Shawn:

36 vehicles / 4 weeks

9 vehicles/week

Brett:

56 vehicles / 7 weeks

8 vehicles/week

9 is greater than 8 so Shawn sells more vehicles per week
