In order to find the number of hats, multiply all the choices together, disregarding size:
4 * 4 * 7 <-- 4 styles * 4 stitches * 7 yarns
= 16 * 7 = 112
112 different hats can be made.
When a number is followed by an exclamation point (!) it means that number gets multiplied by all the numbers below it.
So 7! = 7*6*5*4*3*2*1 = 5040
4! = 4*3*2*1 = 24
6! = 6*5*4*3*2*1 = 720
Now the equation is:
5040 * 24 -720
5040 *24 = 120960
120960 - 720 = 120240
The answer is A.
Answer:
1.B. angles 3 and 4 are supplementary (they add up to make 180)
2. B x+90+63=180
Step-by-step explanation:
anything on a straight line add up to equal 180
Answer:
ok for the first one the lines only cross once 2. lines dont cross 3. its just one line
Step-by-step explanation:
im pretty sure thats right
Answer:
x = 20
Step-by-step explanation:
This isn't too difficult once you understand it.
The bottom left angle of the left triangle (on the other side of 110), that angle is congruent to the 70 degrees angle. that angle is 70 degrees. y = 90 degrees, 90 + 70 = 160
180 - 160 = 20
