160 is the number i believe, hope it helps
12:4=3
9:3=3
so u multiply each side by 3 to get the second triangle..
answer: 4.5*3 =13.5
Answer:
The answer is C.
Step-by-step explanation:
Hit 'em with the Law of Sines.
sin(A)/a = sin(B)/b.
Let's say x is equal to "A", thus 5 is "a".
sin(x)/5 = sin(B)/b.
We could go for the obvious choice for "B", which would be the 90 degrees shown. To solve for the hypotenuse which will be "b", let's use the Pythagorean Theorem:
a^2 + b^2 = c^2
5^2 + 20^2 = c^2
25 + 400 = 425
sqrt(425) = about 20.6, which we can now substitute "b" with.
sin(x)/5 = sin(90)/20.6
sin(x)/5 = 1/20.6
sin(x)/5 = 0.04854...
sin(x) = 0.2427...
You can plug in sin^-1(0.2427) into your calculator, and you should end up with something like 14.047... which equates to answer choice C.
"Centi" means 100 so there are 100 centimeters in a meter. 4 times 100 equals 400 so 4 meters is equal to 400 centimeters.
Answer:
C
Step-by-step explanation:
Gallons of milk = x
Pounds of cheese = y
65 gallons will make 52 pounds of cheese. That is (65, 52)
Given that the relationship is proportion, therefore, the constant of proportionality would be y/x = 52/65
Simplify,
52/65 = ⅘ (4 pounds of cheese to 5 galloons of milk)
The graph that represents the relationship would have a unit rate of ⅘. Or in other words, would have a point (5, 4) which lies on the graph.
Graph C is the right option.
