There are 30 tickets numbered as 1, 2, 3, 4, 30 respectively. One random. What is the probability that the number on the ticket

Anna007 [38]

Answer:

2/3 or 66.66%

Step-by-step explanation:

Out of 30 numbers, half is multiple of 2 and the third is multiple of 3.

We have 15 even numbers and 10 multiples of 3. Out of 10, half is even numbers and therefore counted twice.

<u>So we subtract 5 to get:</u>

15 + 10 - 5 = 20 numbers

<u>If we chose one ticket at random the probability is:</u>

P(2x or 3x) = 20/30 = 2/3 or 66.66%

12-packs of Skwunch apple juice cost $3.00 after a 40% discount. Which equation would allow you to find the original price of th

GaryK [48]

Let x be the original price.

Discount percentage = 40%

Price after discount = $3

So, x - $\frac{40}{100} x$ = 3

$\frac{100x-40x}{100}$ = 3

$\frac{60x}{100}$ = 3

$x = 3(\frac{100}{60} )$

$x=\frac{100}{20}$

x = 5

Hence, the equation that would allow us to find the original price is 0.6x = 3.

Ming has a goal to jog 4 1/2 mile each day. On Monday she jogged 5 9/16 miles. By how much did she exceed her goal for that day?

Darya [45]

5 9/16 - 4 1/2= 1 1/16

I got this because you have make the fractions denomenators equal to subtract them. Once you find how to make them equal you need to mutiply the top numbers the same as the bottom so you can make the new fractions that are equal to the ones before. Then you subtract them and the wholes as well. LOOK BELOW.....

A restaurant used 8 1/4 pounds of carrots to make 6 carrot cakes. Frank wants to use the same recipe. How many pounds of carrots

snow_tiger [21]

Answer:

To make one carrot cake 1 pound(approximately) carrot needed.

Step-by-step explanation:

Given:

8 1/4=33/4 pounds of carrots used to make 6 carrot cakes.

So, to get one carrot cake:

6 carrot cakes need = $\frac{33}{4}$

1 carrot cake need = $\frac{33}{4}$ ÷ $6$

= $\frac{33}{24}$

= $1.375\ pound$

Therefore, to make one carrot cake 1 pound(approximately) carrot needed.
