Around 17,225 cats could be estimated to live in the town
Answer:
z=40 degrees
x=90 degrees
y=40 degrees
Step-by-step explanation:
To solve z you know that 50+90+z= 180 degrees. So z equals 40. To solve x you subtract 90 from 180 to get 90 degrees. To solve you add 50+x+y. You know that x= 90. You would add the angles together to get 180 degrees. 50+90=140 and 180-140 equals 40. Sorry if i'm wrong.
Answer:
36 ft
Step-by-step explanation:
The pole's shadow is 6 times the length of the man's shadow, so the pole is 6 times as high as the man.
6 × 5'11" = 30'66" = 35'6" ≈ 36 ft
Answer:
D
Step-by-step explanation:
For simplify the work we can start to factorise all the possibles expressions:
2x + 8.
8 is multiple of 2, so it can became
2(x+4)
x^2 - 16 this is a difference of two squares, so it can be rewritten as:
(x+4)(x-4)
x^2 + 8x + 16
we have to find two numbers whose sum is 8 and whose product is 16
the two number are 4 and 4
it becames:
(x+4)(x+4)
x+ 4 can‘t be simplified
if we look at the expression, we can find that x-4 appears at the numerator so
x^2 - 16 must be at numerator
but the second factor (x+4) doesn’t appear, so has been simplified. This situation can be possible only in the D option
in fact
(x+4)(x-4)/2(x+4) * (x+4)/(x+4)(x+4)
it became
(x+4)(x-4)/2 * 1/(x+4)(x+4)
(x-4)/2(x+4)
The easiest way to do this is find the area of the large rectangle and subtract the two missing pieces. The length of the large rectangle is 24 and its height is 16. 24x16=384. The area is each of the two missing pieces is 2x2=4. Since there are two of them multiply by two 4x2=8. Then subtract eight from the first area calculated. 384-8=376 square meters
