The ribbon is 66, why?

Do it the hard/easy way.

Add 5 twelve times and you get 60 right? But then half of 12 is 6, so then add 6 to 60. Meaning 66

The ribbon would be 66 inches. This is because there is 12 inches in every foot.

Answer:

1 Roll = $2.50

1 Battery = $1.50

Step-by-step explanation:

From the question we know that,

8 Rolls + 2 Batteries = $23, and

6 Rolls + 2 Batteries = $18

We can subtract the two equations to obtain a third equation,

(8 Rolls + 2 Batteries) - (6 Rolls + 2 Batteries) = $23 - $18

(8 - 6) Rolls + (2 - 2) Batteries = $23 - $18

2 Rolls = $5

Divide RHS and LHS by 2, to obtain the cost of a roll,

2 Rolls / 2 = $5 / 2

1 Roll = $2.50

If one roll costs $2.50 then 6 rolls cost $15,

6 x $2.50 = $15

We plug in this value into the second equation,

$15 + 2 Batteries = $18

Subtract both sides by $15,

$15 + 2 Batteries - $15 = $18 - $15

2 Batteries = $3

Divide RHS and LHS by 2 to obtain the final answer,

2 Batteries / 2 = $3 / 2

1 Battery = $1.50

10. Daniels goes to the shopping center. He has a bank account with a

Savatey [412]

Answer:

-$36

Step-by-step explanation:

Daniel has a starting balance of $259, so anything he spends will be deducted by this amount. To find out how much he spent, we need to add up everything he bought.

He spent $45 + $150 + $100, adding to a grad total of $295.

To find out how much money Daniel has left, we need to subtract his purchases from his funds. This would be $259 - $295. This leaves you with a final answer of -$36 in Daniel's bank account.

An airplane, flying at an altitude of 6 miles, is on a flight path that goes directly over you. If θ is the angle of elevation,

wariber [46]

Answer:

Distance between the person and the plane is 12 miles

Step-by-step explanation:

From the figure attached,

An airplane is flying at an altitude AB = 6 miles.

An observer is standing at point C from where he observes the plane at an angle of elevation θ

Therefore, sinθ = $\frac{\text{\text{Opposite side}}}{\text{Hypotenuse}}$
