Answer:
Step-by-step explanation:
length=1 m
base of triangle=10 m
height=5m
volume= 1/2×10×5×1=25 m cube.
slant height l=√(5²+5²)=√50=5√2
slant surface area=2[5√2×1]=10√2
area of front and back=2×1/2(10×5)=50
total surface area=50+10√2≈50+14.14≈64.14 m²

Step-by-step explanation:
Answer: Cost of tickets for adults = $22
Cost of tickets for children = $15
Total number of tickets sold = 732
Total receipts = $12,912
Let x be number of adult ticket's sold and y be the number of child ticket's sold.
Therefore, we have:
--------------- equation 1

Also, we have:

Now, let's substitute the value of x:






Now, let's substitute the value of y=456 in equation 1, we have:



Therefore, the number of child ticket's sold is 456 and number of adult ticket's sold is 276
Ans is 8 and -1
8 + (-1) = 7
and
8 * (-1) = -8
<span>83 – 2m = 8 + 3m
-2m -3m =</span><span> 8 - 83
-5m =</span> -<span>75
m = 15
so value of m = 15 makes the statement is true</span>
