Answer:
A relation is a function if... none of the x terms repeat. The y terms don't matter.
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:
86.82%
Step-by-step explanation:
A nautical mile = 6,174 feet.
Statute mile =5,360 feet
The percentage of a statute mile to a nautical mile is calculated as:
5360/6174 × 100
= 0.8681567865 × 100
= 86.81567865%
Approximately to the nearest hundredth = 86.82%
Therefore, the percent of a statute mile that is a nautical mile rounded to the nearest hundredth is 86.82%
Next two numbers -80, -160
In this geometric sequence r=2
In the given question there are numerous important information's available. using these information's the answer can be easily deduced. The total number of red roses that Grandma has is already mentioned in the question and it is 14. The total number of pink roses that grandma has is also mentioned in the question and that is 7. Now this is a simple question and the required answer can be reached by simply subtracting the number of pink roses from the number of red roses.
The number of more red roses than pink roses grandma has = 14 - 7
= 7
So Grandma has 7 more red roses than pink roses.
