The constant variation of y=15x is 15 and the constant variation of y=8x is 8 :)
Step-by-step explanation:
2*10+((4+10)x8)/2
=20+14*8/2
=76 sq meters
This is a bit of a tricky one since we are working with thousandths as the denominator. First, we want the common denominator, so we can multiply 8/10 by 100 to get 1000 as that denominator. This gives 800/1000. Next, let's solve the whole numbers. You must add a negative number to a negative number if you want a smaller answer, so we add -5, which means we now have -14 and 800/1000. Now, we subtract absolute value of the larger negative, or our goal, -15 and 465/1000, minus 14 and 800/1000. This yields 665/1000. Now we can add this value to our previous subtraction of 5.
So, the answer is 5 and 665/1000.
Answer:
7/25
Step-by-step explanation:
Probability = # of favorable outcomes / # of possible outcomes
Favorable outcomes = # of blue and yellow marbles
There are 3 yellow marbles and 4 blue marbles
There are 7 blue and yellow marbles so the favorable outcome is 7
Possible outcomes = total number of marbles
12 + 3 + 6 + 4 = 25
There are a total of 25 marbles
So possible outcomes = 25
If probability= favorable outcomes / possible outcomes then the probability of pulling a blue or yellow marble is 7/25
