Answer:

6.08 kg bag unit price: $1.72

7.48 kg bag unit price: $1.86

6.08 kg bag is the better buy

Step-by-step explanation:

To find unit price, divide the price by the amount. 10.47 divided 6.08 equals 1.7203947. Round it to the nearest cent to get 1.72. So, the unit price for the first bag is $1.72. Next divide 13.88/7.48 to get 1.85561. Round it to the nearest cent to get 1.86. So, the unit price for the second bag is $1.86 per kg. The better buy is the cheaper one, so the 6.08 kg bag is a better deal. Hope this helped!

The formula for the volume of a cone is V = 1/3 b × h... b is the area of the base of the cone. The base of the cone is a circle, so we have to use the area of a circle formula... A = pi × radius^2 So first let's find the area of the base... a = pi × radius^2 a = 3.14 × 12^2 (diameter is 24 so radius is 12) a = 3.14 × 144 a = 452.16 in^2 Now we can plug that into the volume of a cone formula... v = 1/3 b × h v = 1/3×452.16 in^2 × 10 in v = 150.72in^2 × 10 in V = 1507.2 in^3

Answers

Answer:

m = -2/3; b = 13 1/3

Step-by-step explanation:

ΔX = 2 – 5 = -3

ΔY = 12 – 10 = 2

2/-3 = -2/3

Equation for b:

$10 = -(2)/(3) (5)+b\n10 = -3 (1)/(3) +b\n13 (1)/(3) =b$

Answer:

-2/3

Step-by-step explanation:

To find the slope, you use rise over run. so 12 - 10 over 2 - 5. That is 2 over negative 3. so negative two thirds. I hope this helps and please mark me brainliest!

a skateboard company is putting together boards and wheels to make skateboards. the company has a box of 36 boards. they need 4 times as many wheels as boards.wheels come in a pack of 20. how many packs of wheels should the company order ?

Answers

If you multiply 36 by four since there are 4 wheels for skateboard
you will get 144. That number is the total number of wheels you need to order and since they come in packs of 20 what you need to do is divide 144 by 20 and you will get 7.2. So obviously you can't order 7.20 packs of wheels so this means that 8 packs of wheels must be bought in order to ensure that all of the skateboards get wheels on them.
The answer is 8.

The airplane has a wingspan of a feet and a tailspan of b feet. If the tailspan in the drawing is 2 inches, and a/b = 3, what is the actual wingspan of the airplane?Scale: 1 inch = 5 feet

Answers

x/2 = 3 (x= 3*2 = 6in)

6in = 30ft

Hope I become the brainliest answer

Answer:

30 feet is correct.

Step-by-step explanation:

Since a = 3b, the wingspan is 6 inches in the drawing, so it is 6x5 = 30 feet on the plane.
