Answer:
The answer is 7.4 × 10³ ( or 0.74 × 10⁴).
Step-by-step explanation:
The steps are :
(1.5 × 10⁴) - (7.6 × 10³)
= (15 × 10³) - (7.6 × 10³)
= (15 - 7.6) × 10³
= 7.4 × 10³
Answer:
15
Step-by-step explanation:
2x3x15 equals to 90
Answer:
the first one.
Step-by-step explanation:
DJ and decorations are one time flat costs. they are constant. so, together, they are $300.
that is what decreases the profit.
on the other side, $5 per student = 5n in total increases our profit.
so, in total the sum of both (the decreasing amount has a negative sign, if course) :
5n - 300 = 1,500
is the right equation to calculate how many students are needed to make that much profit.
the solution, but the way :
5n - 300 = 1500
5n = 1800
n = 1800/5 = 360 students
The hypotenuse is always the longest side, and it is always opposite the right angle.
"Leg" is not a mathematical term. If it is being used to refer to one of the sides forming a right angle, the hypotenuse is not a "leg".
Answer: 110
The 3 figures showed the same pattern by multiplying 2 consecutive whole numbers starting from one. Multiplying 1 by 2 gets 2, 2 by 3 gets 6, 3by 4 results to 12 and so on. If this pattern continues, then 4 will be multiplied by 5, 5 by 6, 6 by 7, 7 by 8, 8 by 9, 9 by 10, and lastly the 10th figure 10 by 11 which is equal to 110.
