Answer:
It may be wrong but complementary angles are 90 degrees so the answer is 44. It may be wrong.
Step-by-step explanation:
As far as I remember, we learned a lot about ratios and fractions, such as adding, subtracting, multiplying, and dividing them, as well as finding LCM and GCF.
Hi there!
To solve this problem you will need to use the cross product method:
1 U.S. dollar → 1.09 euros
x U.S. dollar → 157 euros
To find x, divide 157 by 1.09 :
157 ÷ 1.09 = x
144.036697 = x
144.04 ≅x (You need to round to the hundredths because our answer is in money)
Your answer : If you were to exchange 157 euros you would recieve 144.04 U.S. dollar.
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
212 children, and 265 adults
Step-by-step explanation:
To find the number of children and adults, we can set up a systems of equations.
x= number of children
y= number of adults
Equation 1: Price
1.50x+2.25y=914.25
Equation 2: Total number of people
x+y=477
Now, let's solve the equation using substitution.
Rearrange the second equation to solve for one variable.
x+y=477
x=477-y
Now plug x equals into the first equation, and solve for y.
1.50x+2.25y=914.25
1.50(477-y)+2.25y=914.25
715.5-1.50y+2.25y=914.25
715.5+0.75y=914.25
0.75y=198.75
y=265
We just solved for the number of adults. Now let's plug y equals into the second equation to find the number of children.
x+y=477
x+265=477
x=212
