Answer:
1. First box, the missing fraction = 1/10
2. For the 2nd box
a. The missing fraction = 3/10
b. Percentage = 30%
3. For 7/10
Percentage = 70%
Step-by-step explanation:
From the question given above, the following data were obtained:
The strip is divided into 10 equal parts.
1. For the first box:
The missing fraction = 1/10
2. For the 2nd box
a. The missing fraction = 3/10
b. Percentage = 3/10 × 100 = 30%
3. For 7/10
Percentage = 7/10 × 100 = 70%
Answer:
Is this the full question?
Answer:
Step-by-step explanation:
Step 1: Sum of angles on a straight line is 180
Step 2:
2x + 25 + y = 180
2x + y = 180 - 25
2x + y = 155 (1)
Step 3:
3x - 10 + y = 180
3x + y = 180 + 10
3x + y = 190 (2)
Step 4: Substract equation 1 from 2
3x + y - 2x - y = 190 - 155
x = 35
Step 5:
Substitute x in equation 1 to find y
2x + y = 55
2(35) + y = 155
70 + y = 155
y = 155 - 70
y = 85
no it isn't. 2cos(x) is 2 multiplied by cos(x), cos (2x) is cos(2 multiplied by x) meaning 2x is the angle you're taking the cosine of. if you want to know what cos(2x) look up the double angle rule.
