Answer:
2.50t + 350 = 3t + 225
Step-by-step explanation:
Let t represent the number of tickets that each class needs to sell so that the total amount raised is the same for both classes.
One class is selling tickets for $2.50 each and has already raised $350. This means that the total amount that would be raised from selling t tickets is
2.5t + 350
The other class is selling tickets for $3.00 each and has already raised $225. This means that the total amount that would be raised from selling t tickets is
3t + 225
Therefore, for the total costs to be the same, the number of tickets would be
2.5t + 350 = 3t + 225
<u>1 is a rational number</u> because 1 can go into 1 when dividing. <u>Irrational numbers are mostly decimals. </u>
Answer:
5229 mm³
Step-by-step explanation:
Volume of square pyramid
b = base length = 25 mm
H = height
We have to find 'H' using Pythagorean theorem,
slant height (hypotenuse) = 28 mm
leg₁ = base length ÷ 2 = 25÷2 = 12.5
leg₂ = H
H² + (12.5)² = 28²
H² = 784 - 156.25
= 627.75
H = 25.01 mm
= 5229 mm³

Step-by-step explanation:
Answer:
Volume_stack = 214 n^3
Step-by-step explanation:
The volume of the stack is the sum of the volume of the two boxes
The rectangular box has a volume of
V_rectbox = long*wide*height
V_rectbox = 6 in * 5in * 5 in = 150 in^3
The volume of the cube is
V_cube = long*wide*height , but since all its sides are equal
V_cube = side^3 = (4 in)^3 = 64 in^3
Volume_stack = V_rectbox + V_cube = 150 in^3 + 64 in^3
Volume_stack = 214 n^3
