4. Muthu had 4 times as many stamps as

RSB [31]

Answer:

20 stamps

Step-by-step explanation:

Let x be Muthu's original count

Let y be Sangeetha's original count

x = 4y

x - 12 = y + 12

y = x - 24

x = 4(x - 24)

x = 4x - 96

3x = 96

x = 32

so 32 - 12 = 20

Can someone please help me with this problem!

Anna71 [15]

Answer:

11 yards

Step-by-step explanation:

The volume of a cone formula is:

$V=\frac{1}{3}\pi r^2 h$

Where V is the volume,

r is the radius (half of diameter)

h is the height

Given,

h = 15

V = 475.17

We find the radius (r) first by substituting given values:

$V=\frac{1}{3}\pi r^2 h\\475.17=\frac{1}{3}\pi r^2 (15)\\475.17=5\pi r^2\\r^2=30.25\\r=5.5$

The radius (r) is 5.5 yards

We need the diameter, which is DOUBLE THE RADIUS, so diameter would be:

Diameter = 5.5 * 2 = 11 yards

Find the area of the blue shape below. Use 3.14 for π

Anika [276]

Answer:

1413.86 ft^2.

Step-by-step explanation:

The diameter of the circle = 50 - 2(18)

= 50-36

= 14 ft.

So its radius is 7 ft.

The total area of the blue shape

= 2(35 * 18) + 3.14*7^2

= 1413.86 ft^2.

I need this for my Homework for Labor Day

fomenos

If both containers of orange juice are being sold at the same unit rate, the ratio of ounces to dollars would be the same for the two.

solve the equation by making an inequality:

96 oz. is to $4.80, as 128 oz. is to x

96/ 4.80 = 128/ x

cross multiply 128 and 4.80 to get 614.4

next divide the 614.4 by 96

to get an answer of 6.4

answer: $6.40
