Answer:
$90.38
Step-by-step explanation:
25% of $120.50 is $30.125
$120.50 - $30.125 = $90.375 rounded to $90.38
Answer:
m < ACO = 90 degrees.
Step-by-step explanation:
The line joining the center O of the circle to the point of contact of the tangent is a right angle.
Answer:
Step-by-step explanation:
Pythagorean theorem: base ² +altitude² = hypotenuse²
1) hypotenuse² = base² + altitude²
x² = 6² + 3²
= 36 + 9
= 45
x = √45
x = 6.7 cm
4) base ² +altitude² = hypotenuse²
x ² + 3.7 ² = 4.2 ²
x ² + 13.69 = 17.64
x ² = 17.64 - 13.69 = 3.95
x = √3.95
x = 1.99 cm
10)c ² = a ² + b ²
= 3 ² +4 ²
= 9 + 16
c ² = 25
c = √25 = 5
11) a ² + b ² = c ²
9 ² +b² = 13 ²
81 + b² = 169
b² = 169 - 81 = 88
b = 9.38
12) a² + b² = c²
12² + b² = 22²
144 + b² = 484
b² = 484 - 144 = 340
b =√340 = 18.44
Answer:
15 years
Step-by-step explanation:
<u>Given:</u>
- Number of trees = 167
- This year limit = 4 trees
- Yearly limit following years = 6 trees per year
- Target number of trees = 50
<u>Building inequality:</u>
- 167 - 4 - 8x < 50
- 8x > 113
- x > 113/8
- x > 14.125
Adding current year to 14 we get 15 years as answer
