egoroff_w [7]

First group rate is x+10, Second is x
First group made 160, Second made 120
Time the first group will take is 160/x+10, and second is 120/x
Equation is: 160/x+10 + 4 = 120/x
x=10, x=-30
The second group made 10 suits everyday.

ASAP ILL GIVE BRAINLIEST IF UR RIGHT!!! The radius of the cone is 5 in and y = 13 in. What is the volume of the cone in terms of

Blababa [14]

Answer: V = $100\pi$ $in^{3}$ (third option)

Given Information:

V = $\frac{1}{3}\pi r^{2} h$ <-- volume formula.
r = 5
y = 13
<em>h = ?</em>

To find h...

h, r, and y make a right triangle.
h and r are the two legs, y is the hyptenuse.
$h^{2} + r^{2} = y^{2}$
$h^{2} + 5^{2} = 13^{2}$
$h^{2} + 25 = 169$
$h^{2} = 144$
h = 12

Use formula:

V = $\frac{1}{3}\pi r^{2} h$
V = $\frac{1}{3} \pi (5)^{2} (12)$
V = $\frac{1}{3} \pi (25)(12)$
V = $\frac{1}{3} \pi (300)$
V = $100\pi$

monitta

Answer: $1.663\times 10^{30}\ gm$

Step-by-step explanation:

Given

Population of dust particle doubles every 30 minutes

If the initial sample is 21 grams

The model to predict the population will be

$\Rightarrow P=21\cdot 2^{2t}$

Where t=time in hours

A day has 24 hours . So, for 2 days time is 48 hours

Population is given by

$\Rightarrow P=21\cdot 2^{2\times 48}\\\\\Rightarrow P=21\times 2^{96}\\\\\Rightarrow P=1.663\times 10^{30}\ gm$
