Answer:

It is -6.

Step-by-step explanation:

7 + 12 is 19

b + (7 + 12) = 13

b + (19) = 13

-6 + 19 = 13

The answer you are looking for is b = -6.

There are 2 ways to find this. You could use...

  1. Add together 7 and 12 to get 19, then subtract 19 from both sides to get b = -6. OR...
  2. Subtract 12 from both sides to get b + 7 = 1, then subtract 7 from both sides to get b = -6.

Either way, you will get the same answer of b = -6. One method is just longer than the other. I hope this helps!

liraira [26]

Answer:

  39 cups

Step-by-step explanation:

If we assume that the 3.5 cups of concentrate make 3.5+3 = 6.5 cups of tea, we can use the proportion ...

  6.5/3.5 = x/21

to find the x cups of tea Ahab can make with 21 cups of concentrate.

Multiplying by 21, we get ...

  x = 21(6.5/3.5) = 39

Ahab can make 39 cups of tea.

The volume inside of a sphere is V=4πr33 where r is the radius of the sphere. Your group has been asked to rearrange the formula
Semmy [17]

Answer:

Therefore,

r=\sqrt[3]{\frac{3V}{4\pi }}

is the required r

Step-by-step explanation:

Given:

Volume of inside of the sphere is given as

V=\frac{4}{3} \pi r^{3}

where r is the radius of the sphere

To Find:

r =?

Solution:

We have

V=\frac{4}{3} \pi r^{3}   ......Given

3\times V=4\pi r^{3} \\\\\therefore r^{3}=\frac{3V}{4\pi } \\\\\therefore r=\sqrt[3]{\frac{3V}{4\pi }} \textrm{which is the expression for r}

Therefore,

r=\sqrt[3]{\frac{3V}{4\pi }}

is the required r

: A marker in the shape of a cylinder has a diameter of 14 mm and a height of 136 mm. Find the volume of the figure described. U
Lerok [7]

Answer:

The volume of the figure is 20,925.0mm^3.

Step-by-step explanation:

Firstly we know that the Diameter = 14mm and Height = 136mm.

Area of Circle = 3.14xR^2    Radius = Diameter / 2

Area of Circle = 3.14x7mm^2 = 153.86mm

Volume = 153.86 x 136 = 20,924.96

Then round, to get 20,925.0

Let me know if this is helpful
