Answer:
A
Step-by-step explanation:
Okay cool, so basically the formula is a^2 + 2a square root a square over 4 + h square.
We have to us e the Pythagorus theorem to find the height.
3^2 + h^2 = 36
9 + h^2 = 36
h^2 = 27
h ~ 5
Let's plug in the values from the formula.
The closet answer should be A
Y=-5/2+13
Graphing it out is probably the easiest way to learn
Answer:
Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.
Step-by-step explanation:
Boxers = b
Spaniels = s
Now you have two equations - one that tells you the number of boxers in relation to spaniels and one telling you the number of each breed in relation to the total number of dogs. Solve using substitution.
There are
6 spaniels.
