concert cost $75 each, and tickets to sit on the lawn
during the concert cost $40 each. Organizers of the
concert announced that 350 tickets had been sold
and that $19,250 had been raised through ticket sales
alone. Which of the following systems of equations
could be used to find the number of tickets for bench
seats, B, and the number of tickets for lawn seats, L,
that were sold for the concert?
Answer:
BENCH:150
LAWN:200
Step-by-step explanation:
B+L=350
75B+40L=19250
75B+40(350-B)=19250
75B+14000-40B=19250
75B-40B=5250
35B=5250
B=150
L=200
Answer: the answer is 40 units squared
Step-by-step explanation:
the SA with a rectangular and square base is 2*s²+4*s*h
2*s²= the surface area
4*s*h= sideways (lateral)
s= 2 and h=4
so then plug it into "2*s²+4*s*h" and you get 2*2²+4*2*4
2*2²+4*2*4
2(4)+32
40
Answer:
b = 12
Step-by-step explanation:
The mistake Megan has made is that she has squared the lengths and then added it instead of taking away the squared length's. The method she used was to work out the hypotenuse, so the correct method would be as follows:
a² + b² = c²
→ Substitute in the values
5² + b² = 13²
→ Simplify the equation
25 + b² = 169
→ Minus 25 from both sides to isolate b²
b² = 144
→ Square root both sides to find the value of b
b = 12
People were invited to a party. 5 people were Invited but only 2 people came (2/5). Then , apparently, half of the people (1/2) invited from a different party came to that one. 2 lots of that 1/2.2/5 x 1/2. I hope this helps.
