Answer: x = 7
Step-by-step explanation:
sure thing! so, one angle is 34 degrees, and the other clear angle is 60 degrees. we know that because the angle on the lower shape matches that one. we then just add those, which comes out to 94 degrees. a triangle is 180 degrees, so we subtract 94 from that in order to figure out the total degrees in that last angle. that angle comes out to be 86 degrees. then, we subtract 2 in order to divide easily. we then divide 84 by 12, and we get 7. so, x = 7
Answer:
Scale factor = ½
Step-by-step explanation:
The original image is the preimage = ∆ACB
The new image is the image = ∆DFE
The scale of factor of dilation = image/preimage = DF/AC
DF = 6 cm (given)
AC = 12 cm (given)
Plug in the values into the equation to find the scale factor of dilation:
Scale factor = 6/12
Scale factor = ½
There are 63 students in the room, this is because 21 time 3 gives you 63.
5 bags with 6 flower bulbs in each equals 30.
He planted all but 3
30-3=27
Leonard planted 27 bulbs
I'm assuming your function is f(x) = -9^(x+1)
So we just have to plug in and see if the function is true.
1) -9^(0+1) = -9^1 = -9
YES
2) -9^(1+1) = -9^2 = -81
NO
3) -9^(-1+1) = -9^0 = -1
YES
