Natalka [10]3 years ago

Answer:

Solution:-

(106)³ - (94)³

(100+6)³ - (90 + 4)³

(100 + 6)³ = (100)³ + 3 × (100)² × 6 + 3 × 100 × (6²) + (6)³ [By using the identity (x+y)³ = x³+3x²y+3xy²+y³]

= 1191016

(90 + 4)³ = (90)³ + 3 × (90)² × 4 + 3 × 90 × (4)² + (4)³ [By using the same identity] = 830584

1191016 - 830584

= 360432  Answer.

Tickets to a school play cost $2 if bought in advance and $3 at the door. By selling all 400 tickets, $1030 was collected. First
Marrrta [24]

Answer:

170 tickets.

Step-by-step explanation:

Write formulas for the question.

N_2+N_3=400

2N_2+3N_3=1030

Then use substitution.

N_2=-N_3+400

2(-N_3+400)+3N_3=1030

-2N_3+800+3N_3=1030

N_3=230

So number of $3 tickets sold is 230. But they ask for the tickets bought in advance (i.e. the tickets sold for $2). Use substitution again.

N_2+230=400\\N_2=400-230\\N_2=170

An airplane flies 2700 miles to Los Angeles to NYC. When the plane flies back to LA, is it flying in a negative direction? use a
dolphi86 [110]

Answer:

Distance = abs(-1700)

Distance = 1700 miles

Step-by-step explanation:

NYC is located East of Los Angels.

The Airplane flies from Los Angeles to the left direction from NYC.

Which is negative direction.

Therefore, distance = -1700

Here the distance cannot be negative even though if it flies in negative direction.

Therefore, we use the absolute value.

The absolute value of a number is always positive.

So, distace = abs( -1700)

Distance = 1700 miles.

Hope this will help you understand the concept.

Thank you.
