If seven friends eat out and split a bill, we must first figure out how much each person would pay individually. To find this number, we need to divide the total bill by the total number of people. $100. 10/7 = 14.3, so each person payed $14.3 individually. If three friends only brought cash so they pay Henry to pay for their portion on credit card, then Henry would pay for those three friends and himself on a credit card, or just 4 times how much one of them payed. Since each of them payed 14.3, then to find out how much Henry payed on credit card, we need to multiply 14.3 by 4 which gives us our answer of $57. 12
Answer:
450 in^2
Step-by-step explanation:
Width = 15 Length is twice as much = 30 in
Area = L * W = 15 * 30 = 450 in^2

Answer:
5, 25
Step-by-step explanation:
When you multiply any two whole numbers with each other and get 125 as the answer, you can say that both the numbers will be the factors of 125. 1× 125 = 125 and 5 × 25 = 125; thus, the factors of 125 are 1, 5, 25, and 125.
There is actually a cool trick to this. When you see a and 2a, in this case 6 and 12, then the small triangle is a 60-30-90 triangle. The remaining side is
.
This value rounds down to 10, and yep, you guessed it, another 30-60-90.
This time, x =
.
This is a very difficult problem and requires knowledge of the special triangles. Hope this helps!
