3 friends share the cost of a gift. The gift costs $70, but the store manager takes $10 off the market price. What amount should

My name is Ann [436]

Answer:

Amount each friend pays for the gift = $20

Step-by-step explanation:

Market price of a gift = $70

The store manager takes $10 off the market price.

Marked down amount = $10

New cost price = Marked price - Marked down amount $=\$70-\$10=\$60$

The cost of the gift is divided among three friends.

This means that the cost of gift which is $60 is divided by three to get each one's contribution in the gift.

∴ Amount each friend pays for the gift $=\frac{60}{3}=\$20$

What is the area of a sector with a central angle of 2π/9 radians and a radius of 16.7 ft?

Y_Kistochka [10]

Answer:

Area of the sector is 97.30 square feet.

Step-by-step explanation:

The area of the sector is given by

$A=(\frac{\theta}{2})r^2$

Plugging the known values in this formula to find the area of the sector

$A=(\frac{2\pi/9}{2})(16.7)^2\\\\A=\frac{2\pi}{18}\cdot16.7^2$

Use the value of π as 3.14

$A=\frac{2\cdot3.14}{18}\cdot16.7^2$

Simplifying, we get

$A=97.3016$

Rounded to the nearest hundredth, we get

$A=97.30$

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 50 pounds each, and the small boxes

skad [1K]

So this is how we are going to solve for the given problem above.
Given that x = number of large boxes
and 120-x = number of small boxes.
So here is the solution:
50x + (120-x)20 = 4050
50x + 2400 - 20x = 4050
30x + 2400 = 4050
30x = 4050 - 2400
30x = 1650 <<divide both sides by 30
x = 55.
Therefore, there are 55 large boxes
120 - x = small boxes
120 - 55 = 65 small boxes.
Hope this is the answer that you are looking for.
Let me know if you need more help next time!
