Answer:
x = 1
Step-by-step explanation:
Set up a proportion
x/0.25 = 6/1.5
1.5x = 1.5
x = 1
Thus, x = 1
The answer is 18…………………..
Answer:
Her brothers pulse rate is 76.
Step-by-step explanation:
95% of 80 is 76. That only means that her brother's pulse rate must be 76 beats per minute.
Answer:
x = 29°
The angles are 137° , 116° , 96° , 44° and 147°
Step-by-step explanation:
The sum of the angles of the polygon is given as 540°. The angles are given as 5x – 8°, 4x°
, 96° , 44°, 5x + 2. Therefore, the value of x can be found as follows
5x – 8° + 4x° + 96° + 44° + 5x + 2° = 540°
collect like terms
5x + 4x + 5x - 8 + 96 + 44 + 2 = 540°
14x + 134 = 540°
14x = 540 - 134
14x = 406
divide both sides by 14
x = 406/14
x = 29°
Therefore, the angles are as follows
29 × 5 - 8 = 137°
29 × 4 = 116°
96°
44°
5 × 29 + 2 = 147°
Step-by-step explanation:
so the correct answer is 3³
