kattie and matt are both flying kites on a breezy day. the string of katies kite is extended 864 feet, and her kite makes a 38 angle of elevation with the ground. the string of matt's kite is extended 725 feet, and his kite makes a 40 angle of elevation with the ground. Whose kite is flying higher in the sky
Answer:
Kattie's kite is flying higherStep-by-step explanation:
Let the height of each kite be h.
The h is opposite to angle of elevation and the sting length is hypotenuse of the formed triangle.
Kattie's kite:
h/864 = sin 38°h = 864 sin 38°h = 532 ft (rounded)Matt's kite:
h/725 = sin 40°h = 725 sin 40°h = 466 ft (rounded)Kattie's kite is flying higher as 532 ft > 466 ft

Solve for x in the diagram below.
45°
15°
4x
Answer:
15°
Step-by-step explanation:
45 + 15 = 60° (which is 4x since they're vertically opposite angles)
4x = 60°
x = 60 ÷ 4 = 15

Scott set up a volleyball net in his backyard. One of the poles, which forms a right angle with the 15) ground, is 7 feet high. To secure the pole, he attached a rope from the top of the pole to a stake 5 feet from the bottom of the pole. To the nearest tenth of a foot, find the length of the rope.
Answer:
8.6 feets
Step-by-step explanation:
From the scenario described :
The length of the rope, h is the hypotenus. From the data Given, we cannot obtain how far wthe bird will need to fly directly, we use Pythagoras rule to calculate the hypotenus of the triangle :
Hypotenus, h = sqrt(opposite² + adjacent²)
h = sqrt(7² + 5²)
h = sqrt(49 + 25)
h = sqrt(74)
h = 8.6 feet

3 : Which tank has the greater volume?
Tank A has a diameter of 10 ft and a height of 3 ft. Tank B has a diameter of 6 ft and a height of 8 ft
Answer:
1,Area = πr² Circumference = 2 πr So first we solve for r from area: 25 π = πr² 25 = r² r = 5 So we know that radius is 5 cm. Now substitute r to 5 in circumference formula: C = 2π(5) = 10π

Arnav is selling boxes of cookies.
He sells each box for $3.75.
His goal is to make more than $30.
How many boxes of cookies could he sell to reach his
goal?
Arnav needs to sell more than 8 boxes of cookies to reach his goal of making more than $30. Since the number of boxes must be a whole number, Arnav would need to sell at least 9 boxes of cookies to achieve his goal.
To determine how many boxes of cookies Arnav needs to sell to reach his goal of making more than $30, we can set up an inequality based on the selling price of each box.
Let's represent the number of boxes he sells as "x". Since each box is sold for $3.75, the total amount of money he will earn from selling "x" boxes is 3.75x.
To reach his goal of making more than $30, we can write the following inequality:
3.75x > 30
To solve for "x", we divide both sides of the inequality by 3.75:
x > 30 / 3.75
Simplifying the right side of the inequality, we get:
x > 8
To fulfil his objective of earning more than $30, Arnav must sell more than 8 boxes of cookies. Arnav would need to sell at least 9 boxes of cookies in order to reach his objective because the number of boxes must be a whole number.
