Answer:
1. Increase £92 by 40% = £128.8
2. Increase £150 by 13% = £169.5
3. Decrease £75 by 80% = £15
4. Decrease £440 by 18% = £360.8
Step-by-step explanation:
1. Increase £92 by 40%
40/100 + 92
0.4X92
36.8
92+36.8
£128.8
2. Increase £150 by 13%
13/100 X 150
0.13X150
19.5
150+19.5
£169.5
3. Decrease £75 by 80%
80/100 X 75
0.8X75
60
75-60
£15
4. Decrease £440 by 18%
18/100 X 440
0.18X440
79.2
440-79.2
£360.8
Answer:
D
Step-by-step explanation:
Using trigonometric ratios in the right triangle
tan45° = 1 and cos45° =
tan45° = =
Multiply both sides by 7
7 × tan45° = b, that is
b = 7 × 1 = 7
--------------------------------------------------------
cos45° = =
Multiply both sides by a
a × cos45° = 7, that is
a × = 7
Multiply both sides by
a = 7
Answer:
y = (y2 -y1)/(x2 -x1)x +(y1 -(y2 -y1)/(x2 -x1)x1)
Step-by-step explanation:
You can use two points (x1, y1) and (x2, y2) from the table to make the following computations:
The slope (m) is ...
m = (y2 -y1)/(x2 -x1)
and the y-intercept (b) can be computed from ...
b = y1 -m(x1)
Then put these into your equation ...
y = mx +b
