Step-by-step explanation:
Taking value of x= 4
16. 4 + 8 = <u>12</u>
17. 24 ÷ 4 = <u>6</u>
18. 3(4+4) = 3 × 8 = <u>24</u>
19. 5 × 4 = <u>20</u>
20. 30 - (5 × 4) = 30 - 20 = <u>10</u>
21.( 2 × 4 )+ 5 = 8 + 5 = <u>13</u>
22. 4 + 1 = <u>5</u>
23. 25 × 4 = <u>100</u>
24. 60 × 4 = <u>240</u>
25. (25×4) + 10 = 100 + 10 = <u>110</u>
Answer:
B.56
Step-by-step explanation:
80x0.70 is 56
Answer:
A) 75%
B) 76
Step-by-step explanation:
A) 39/52=0.75=75%
B)80x0.95=76
1/4 + 1/3 + 1/6 + 1/8 + 1/8
Must have same denominators
6/24 + 8/24 + 4/24 + 3/24(2)
Answer: 1
Answer:
A 2√2(cos 7π/4 + i sin 7π/4)
Step-by-step explanation:
A. 2√2(cos 7π/4 + i sin 7π/4)
2 sqrt(2) ( sqrt(2)/2 - sqrt(2)/2 i)
Distribute
2-2i
This is in the fourth quadrant
B. 2√2(cos 150° + i sin 150°)
2 sqrt(2) (-sqrt(3)/2 +1/2i)
-sqrt(6) +sqrt(2) i
This is in the third quadrant (NO)
C. 2(cos 7π/4 + i sin 7π/4)
2( ( sqrt(2)/2 - sqrt(2)/2 i))
sqrt(2) - sqrt(2) i
This is the fourth quadrant
D. 2(cos 90° + i sin 90°)
2(0+i)
2i
This is on the positive y axis NO
Now we need to decide between the two in the fourth quadrant.
The point has an x coordinate of 2 and a y coordinate of -2
This aligns with point A
