Convert foot to inches:

1 foot = 12 inches

23 feet ⇒  23 feet × 12 inches/ft = 276 inches

Divide:

276 ÷ 9 = 30 pieces with remainder

Remainder = 276 - (9×30)  ⇒  276 - 270 = 6

ANSWER: There will be 6 inches long remaining in length after cutting the string into 30 pieces equal lenght of 9 inches each.

Cameron buys 2.45 pounds of apples and 1.65 pounds of pears. Apples and pears each cost c dollars per pound. If the total cost a
Leto [7]

Answer:

2.45c + 1.65c = 4.12 + 0.75

Step-by-step explanation:

To write an equation to find the value for c, we need to declare what c is first.

c = price of fruit

2.45c + 1.65c = 4.12 + 0.75

Now we multiplied c to 2.45 and 1.65 and added them together, because whatever the value of c is will give us the equivalence of the sum of 4.12 + 0.75.

Now to check if the equation is right, let's solve for c.

2.45c + 1.65c = 4.12 + 0.75

4.1c = 4.87

Now to get the value of c, we divide both sides of the equation by 4.1.

\dfrac{4.1c}{4.1}=\dfrac{4.87}{4.1}

c = 1.19

Now let's substitute the value of c in the equation to see if we got it right.

2.45(1.19) + 1.65(1.19) = 4.12 + 0.75

2.92 + 1.96 = 4.87

4.87 = 4.87

Therefore concluding that the value of c is 1.19.

Find the equation of the tangent line at the point (1, 6). for y = 4 + 4x2 - 2x3.
Lostsunrise [7]
y = 4 + 4 x^{2}-2x^{3}  Lets \ write \ it \ y = -2 x^{3} +4 x^{2} +4

The tangential line at a certain point is just the derivative so.
y ' = -6 x^{2} +8x. At the point (1,6) we plug the x value in and get the slope at the point (y ' = 2)

The tangential line at that point is
y - 6 = 2(x - 1)     (this is the answer)

Answer: 41 vans will be needed.

Step-by-step explanation:

There are a total of 492 campers. We know that each van can hold a total of 12 passengers.

So, simply divide 492 by 12 to get the total amount of vans needed.

492/12 = 41 vans.
