If the band is earning $1,500 on ticket sales, that is equal to 2/3 aka 6/15. (found by multiplying the fraction by 3/3 aka 1) 1/5 aka 3/15 is earned on merchandise. Since 3/15 is half of 6/15, that means that merchandise makes half of $1,500, (1500÷2) or $750.
So, the band earns $750 from merchandise :)
Answer:
66
Step-by-step explanation:
This was the formula that I used V=14h √(a+b+c)(b+c−a)(c+a−b)(a+b−c)
Hope this helps! :)
Answer:
12 meters
Step-by-step explanation:
Looking at the problem we can see that it typifies a right angled triangle. The rope running from the top of the flagpole to the hook on the ground is the hypotenuse of the triangle. Let us call this hypotenuse c. Let the distance between the hook and the foot of the flagpole be b. Let the height of the flagpole be a.
From Pythagoras theorem;
c^2 = a^2 + b^2
a^2= c^2 - b^2
a= √c^2-b^2
From the question
c= 13 metres
b= 5 metres
a= the unknown
a= √c^2-b^2
a= √(13)^2 - (5)^2
a= √169 - 25
a= √144
a= 12 meters
In mathematics, a proof is a deductive agruement for a mathematical statement.In the argument,other prevoiusly establised statements, such as theroms, an be used. In principle, a proof can be traced back to self-evident or assumed statements, known as axioms, along with accepted rules of inference.
