Answer: 24
Step-by-step explanation:
The other information regarding the question is that the Medium pizza cost $9 while the Large pizza cost $15.
The number of medium sized pizza that Wright sold will be represented by x.
(5 × $15) + ($9 × x) = $291
$75 + 9x = $291
9x = $291 - $75
9x = $216
x = $216/9
x = 24
He sold 24 medium pizza

*see below regarding significant digits
Step-by-step explanation:
Set up a grid to help you to know whether to divide or multiply. Stack equivalent values one on top of the other in your grid. Arrange them so that the units will cancel out. This helps you to change the units. See image.
*if you are also learning about "significant digits" then you will have to alter the answer to only include the same number of significant digits as in the question.
The exact calculated answer is 2494.756, but there are only two significant digits in the question, so the answer maybe 2500kg instead. If your teacher hasn't taught sig figs then go with the exact answer.
2494.756kg
Answer:
45
Step-by-step explanation:
45 = 3*3*5
180 = 2*2*3*3*5 <---- so the other number had to contain a factor of 2*2 or 4
also, let the other number has to be of the form 3k and it must contain a factor of 4, how about 12 ?
check: lcf of 12 and 45 is 3,
the lcm of 12 and 45 is ...
12 = 2*2*3
45 = 3*3*5
so we need: 2*2*3*3*5 = 180
Answer:
1/15
Step-by-step explanation:
First you must figure out your total outcomes, int the problem it said ten. Than take the number of students and put the number of students over the number of outcomes. This will tell you the probability of drawing one student. Next you must subtract 1 student and one member from your original equation. This is because you have assumed that the first drawing had a favorable outcome. So that leaves you with 2/9. Next you must multiply both the first fraction (3/10) and the second fraction (2/9) to come up with the total probability of the event occurring.
Hope that helped.
