Answer:
r = -6
Step-by-step explanation:
6r + 7 = 13 + 7r
-6r both sides
7 = 13 + r
-7 both sides
r + 6 = 0
-6 both sides
r = -6
The distance between the ground and the kite to the nearest foot is 64 ft.
<h3>What is a right angle triangle?</h3>
A right angle triangle is a triangle that has one of its sides as 90 degrees. The situation forms a right angle triangle.
Hence,
The length of the kite string is the hypotenuse side of the triangle formed.
The height between the ground and the kite is the opposite side of the triangle formed.
Therefore, using trigonometric ratio,
sin 40 = opposite / hypotenuse
sin 40 = h / 100
cross multiply
h = 100 sin 40
h = 100 × 0.64278760968
h = 64.2787609687
h = 64 ft
Therefore, the distance between the ground and the kite to the nearest foot is 64 ft.

Answer:The total amount of money that the school will spend for tickets is $9900
Step-by-step explanation:
Tickets to a baseball game are 20 dollars for an adult and 15 dollars for a student. A school bus tickets for 45 adults and 600 students. This means that the total amount spent by the school on adult tickets is 20 × 45 = $900
The total amount spent by the school on students tickets is 15 × 600 = $9000
The total amount of money that the school will spend for tickets will be the sum of the amount spent on adult tickets and student tickets. It becomes
900 + 9000 = $9900
The given question is incomplete. The complete question is:
A farmer sells 9.9 kg of pears and apples at the farmers market. 3/4 of this weight is pears,and the rest is apples.how many kilograms of apples did she sell at the farmers market.
Answer: The farmer sells 2.475 kg of apples.
Step-by-step explanation:
Given : Total weight of pears and apples = 9.9 Kg
of the total weight is pears
Hence, weight of pears = 
Therefore weight of apples = Total weight - weight of pears = (9.9 -7.425) = 2.475 Kg
The answer is g=13 I hope this helped
