Annie and Emily are sisters. Emily’s age is 7 more than twice Annie's age, a. The sum of their ages is 45. Which equation represents this relationship?
Answer:
3x=38
Step-by-step explanation:
Given that,
Annie and Emily are sisters. Emily’s age is 7 more than twice Annie's age, a. The sum of their ages is 45.
Let Annie's age is x.
Emily's age = 7+2x
ATQ,
The sum of their ages is 45.
x+7+2x = 45
Taking like terms together,
x+2x = 45-7
3x=38
Hence, this is the relation between their ages.

You go to the park on a windy day to fly a kite. You have released 40 feet of string. The string makes an angle of 36° with the ground. How high is the kite in the air?
Answer:
68ft
Step-by-step explanation:
Sin36=o/h = opposite / hypotenuse
x=40/Sin36
x=68
The kite in the air is 23.512 feet.
What is trigonometry ?Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.
Given:
String length= 40 feet
Angle of elevation = 36
Now using concept of application of Trigonometry
sin 36= P/H
0.5878= P/40
P= 23.512 feet.
Hence, the kite in the air is 23.512 feet.

What is the solution to the trigonometric inequality sin(x)>cos(x) over the interval 0<=x<=2piradians?
ANSWER: C
Answer:
x > π/4Step-by-step explanation:
Given the inequality expression
sin(x)>cos(x)
Divide both sides by cos(x)
sin(x)/cos(x)>cos(x)/cos(x)
tan(x) > 1
x > tan⁻¹1
x > 45⁰
x > π/4
Hence the required solution is x > π/4
Brian is going camping and. is making a tent from fabric. How much fabric will he need? 6 ft. 12.5 ft. 8.5 ft.
Answer and explanation:
Depending on the type and size of tent you wish to make, an average tent should consume more than 12.5ft of fabric. You would require more than 10 yards of fabric to make a small tent that an adult human being can fit in.
1 yard = 3 ft
And so you would require about 30 ft of fabric to make your tent. Therefore the options listed may not be enough fabric to make a tent
