Answer: There are 41 dimes and 11 pennies in the cup.
Step-by-step explanation:
We know that 1 dime = 0.1 dollars
1 penny = 0.01 dollars
Let p be the number of pennies and d be the number of dimes.
Then we have the following equations :_
Substitute the value of d from (1) in equation (2), we get
Then , Put value of p in (1), we get
Hence, there are 41 dimes and 11 pennies in the cup.
Answer:
Step-by-step explanation:
14) since this is a square each side is going to be the same length; all sides will be 9 ft long
x + 2 = 9 9 - 2 = 7 X = 7
to get the area of the square you must find the length of one side.... we know it is 9.... then we multiply the length by itself.... in this case 9 x 9
9 x 9 = 81 ft
15) formula to find the area of a right triangle is: A = ab/2
In this case a = 8cm and b = (x + 1) cm
In order to meet the requirement of ≤ 44 ab must = ≤ 88
since we multiply ab then x has to be 10 or less since 10+1=11
and 11 x8 = 88 and 88 divided by 2 = 44
Answer: 18
Step-by-step explanation: 16/2 = 8 - 6 = 2 x 10 = 20 - 2 = 18, sorry if i'm incorrect.
