How do you solve this?

The plane needs to be about 27 meters higher to clear the tower

Step-by-step explanation:

The plane is 42 meters away from the tower.The tower is 98 meters high. Applying the Pythagorean relationship where the tower height is b and the distance of plane from tower is a, after take off, the plane reaches a flight distance of 83 meters from the ground at an angle.Finding b

a²+b²=c²

42²+b²= 83²

b²=83²-42²

b²=5125

b=√5125

b=71.59 meters

After travelling 83 meters, the plane will have cleared about 72 meters of the tower.

The remaining meters to clear the height of tower is: 98-72= 27 meters

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
