Answer:
59.6 square units
Step-by-step explanation:
The area is given by the formula ...
area = (1/2)ac·sin(B)
Fill in the given numbers and do the arithmetic.
area = (1/2)(11)(11)(sin(100°)) ≈ 59.6 . . . . square units
Answer:
Step-by-step explanation:
Just translate the words to numbers. Twice the number of dimes is 2d . Five less means subtract 5 from that. thats the nunber of nickels: n
So your first equation is n = 2d- 5
you know that the value of a nickel is 5 and the value of a dime is 10 and the total value is 115. (skip the decimals for now!) It's all cents. (that should make sense!)
The second equation is 5n + 10d = 115
Substitute the value of n (2d-5) from the first equation into the place of n in the second equation.
5(2d -5) + 10d = 115 now Distribute
10d -25 + 10d =115 and solve for d (add 25 to both sides abd combine d's)
10d + 10d = 115 + 25
20d = 140 divide both sides by 20
d = 7 Put that value in place of d in the first equation and solve for n
n= 2(7) -5 That's 14-5 so n=9
Check values in either equation: 5n + 10d= 115
5(9) + 10(7) = 115
45 + 70 = 115 TRUE! so Jon has 9 nickels and 10 dimes.
First if you know all the fractions and it will be really easy for you to figure this out all you have do is add all the numbers that you have and you will get it good luck!
Answer: -42
Step-by-step explanation:
-4(n-6)+m
and then they give you the values of each
basically what you do is put the value of m into where it shows on the equation as well as the n.
-4(-5-6)+2 and then you should get
-42
