Answer:
40%
Step-by-step explanation:
Step 1: We make the assumption that 675 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100\%=675.
Step 4: In the same vein, x\%=270.
Step 5: This gives us a pair of simple equations:
100\%=675(1).
x\%=270(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x% = 675/270
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100% = 270/675
x=40%
Therefore, 270 is 40% of 675

Answer:
(d) ∠AIS
Step-by-step explanation:
The tangent SF intersects the circle at one point, point I. Any angle it forms with a chord must be a chord that terminates at point I. There are two of them: AI and CI.
The angles these chords make with tangent SF are ...
Of these, only the first (∠AIS) is listed among the answer choices.
Step-by-step explanation:
such a rectangular prism is in that sense like a cube (or die) : it has 6 sides or surface areas. top, down, front, back, left, right.
to get the total surface area we need to calculate each individual side area and sum all 6 of them up.
since it is a rectangular shape, there are 3 pairs of equal side areas, so, we really need to calculate only 3 different ones :
front and back : each is
10×9 = 90 in², both together are 180 in²
left and right : each is
8×9 = 72 in², both together are 144 in²
top and bottom : each is
10×8 = 80 in², both together are 160 in²
the total surface area of the prism is
180 + 144 + 160 = 484 in²
