Answer:
3, 7, 11, 15, 19 is an arithmetic sequence
Step-by-step explanation:
they go up by 4
7.95 + 1.5 = 9.45
6/100 =?/9.45 ?=.567. =10.017
20/100 = ?/10.017 =2.0034 =12.0204
12.0204 = total cost
2.0034 = tip
Answer:
Step-by-step explanation:
In a parallelogram, the opposite sides are equal and parallel.
Also, consecutive angles in a parallelogram are supplementary. This means that the sum of the consecutive angles is 180 degrees.
Angle 2m and angle n are supplementary angles. Therefore,
2m + n = 180 - - - - - - - - - - - -1
Also, the opposite angle in a parallelogram are equal. This means that
2m = 70
m = 70/2
m = 35 degrees
Substituting m = 35 into equation 1, it becomes
2 × 35 + n = 180
70 + n = 180
n = 180 - 70
n = 110 degrees
Given that the two angles form a linear pair, let second angle be x, the first angle will be 3x because it is 3 times the second angle. But linear angles add up to 180, thus
x+3x=180
4x=180
hence
x=180/4
x=45°
thus the measure of the first angle will be :
3x=3*45=135°
the second angle is 45°
