There are 10 circles and 2 triangles. What is the simplest ratio of triangles to total shapes?
barxatty [35]

Answer:

1:6

Step-by-step explanation:

Given that there are 10 circles and 2 triangles, the total number of shapes is equal to 10+2.

10+2=12

Because there are 2 triangles, the ratio of triangles to total shapes is equal to 2:12.

However, this ratio can be simplified because both sides are multiples of 2. Divide both sides of the ratio by 2 to simplify the ratio.

2:12

1:6

Therefore, the simplest ratio of triangles to total shapes is 1:6.

I hope this helps!

There are 140 legs on a planet zids have 5 legs and zods have 7 legs h=how many soulutions are there
abruzzese [7]
Number of zids=x
number of zods=y
number of zid legs=5x
number of zod legs=7y

so
5x+7y=140
try to get it into slope intercept from so you can graph is (y=mx+b)
5x+7y=140
subtract 5x from both sides
7y=140-5x
divide both sides by 7
y=20-5/7x
y=-5/7x+20

plug in numbers for x and get numbers for y (you can only plug in multiples of 7 for x so that there are a whole number of zids and since you are counting, x and y must never be negative)

lets try 0 for x

y=-5/7(0)+20
y=20
 so x=0 and y=20 is an answer (if you can have only one of that species)


lets try 7 for x
y=-5/7(7)+20
y=-5+20
y=15

so x=7 and y=15 is an answer


lets try 14 for x

y=-5/7(14)+20
y=-10+20
y=10

so x=14 and y=10 is another answer


lets try 21 for x
y=-5/7(21)+20
y=-15+20
y=5

so x=21 and y=5 is another answer


lets try 28 for x
y=-5/7(28)-20
y=-20+20
y=0

so x=28 and y=0 is an answer (if there can be only one of a species)


if we go further, then y will be negative so the answers are

(x,y)
(0,20)
(7,15)
(14,10)
(21,5)
(28,0)

if it is allowed that only one species exists then there are 5 possible answers
if both must exist simultaneously, then there are only 3 answers

Answer:

A) p(male)=20/30=2/3

b) p(female) = 10/30=1/3

c) p(11th grade) = 12/30=2/5

d) p(12th grade) = 18/30 = 3/5

e) p( girl and in 11th grade) =4/30=2/15

F) p(12 th grade and female) = 6/30 = 1/5

g) p(male and in 12th grade) = 12/30 = 2/5

h) p(male and if we know the student is female) = 0 if we know the student is male then she can't be male again. these are mutuallyinclusive event and they can't occur at once.FOR more details and solutions,clarification and more explanation contact me via my g mail at [email protected] and I will keep in touch....please leave your comment in thisg mail which is my tutor g mail account please.

18. How can you tell if a fraction will have a repeating decimal
GaryK [48]
Terminating and Repeating Decimals. Any rational number (that is, a fraction in lowest terms) can be written as either a terminating decimal or a repeating decimal . Just divide the numerator by the denominator . If you end up with a remainder of , then you have a terminating decimal.
