Answer:
The answer is C I have the same assignment
Step-by-step explanation:
X + (x+3) = 28
<span>2 x + 3 = 28 </span>
<span>2x = 25 </span>
<span>x = 12.5 </span>
<span>x+3 = 15.5
28-15.5= 12.5
The two lengths are 15.5 and 12.5. </span>
Answer:
Coordinates of the image point → (-2, 9)
Step-by-step explanation:
If a point (x, y) is translated by 'h' units left and 'k' units up then the rule for the translation will be,
(x, y) → (x - h, y + k)
Rule for the translation of a point (2, 7) by shifting 4 units left and 2 units up will be,
(2, 7) → (2 - 4, 7 + 2)
→ (-2, 9)
Coordinates of the image point → (-2, 9)
Answer:
C
Step-by-step explanation:
The surface area (A) of a sphere is calculated as
A = 4πr² ← r is the radius, here r = 12, hence
A = 4π × 12²
= 4π × 144 = 576π units² → C
First we have to make the fractions even so there denominator have to be equal. So 15 times 2 gets 30 and 6 times 5 gets 30 too. Ok now multiply the nominator by the corresponding number of 25/30 and 16/30. Subtract to get 9/30 now simplify to get 3/10.
