Answer:
48 questions.
Step-by-step explanation:
x is for the unknown variable, the number you are trying to figure out.
12= 25%x
if you convert to a fraction, 12 is 1/4 of x. if you then multiply your answer by 4, 12 is 25% of 48.
to figure this out you can also ask, 12 is 25% of what number?
A = 30
B = 41
C = 70
A < B + C
30 < 41+70 ==> 30 < 111 (TRUE)
B < A + C ==>
41 < 30 + 70 ==> 41 < 100 (TRUE)
C < A+B
70 < 30 + 41 ==> 70 < 71 (TRUE)
Yes, can!
if a=3,for example, and B=2, and we plug it in:
p=(3)(2) which is p=6
q=(2)(3) which is also =6
the factor order wont change the product
Answer:
31 pennies
Step-by-step explanation:
Given that:
Breaking the number of pennies into 2 groups, there is 1 penny left over.
Breaking the pennies into 3 groups, there is 1 penny left over.
Breaking the pennies into 5 groups, there is 1 penny left over.
Breaking the pennies into groups implies that the same number of pennies are in each group for each case. Since there is no restriction to the number of pennies in the groups for all cases, then the total number of pennies would be 31.
So that;
31 = 15 + 15 + 1 = 2 groups + 1
31 = 10 + 10 + 10 + 1 = 3 groups + 1
31 = 6 + 6 + 6 + 6 + 6 + 1 = 5 groups + 1
There are 31 pennies.
For this question you should know that 5 hours is equal to 300 minutes so the ratio of 300 minutes to 100 minutes is 300/100 which is equal to 3/1 or 3 :)))
i hope this is helpful
have a nice day
