Answer:

We are expected to find 1,080,000 right handed people in that group of people

Step-by-step explanation:

In this question, we are given the ratio of right handed to left handed people and we are asked to calculate the number of right handed people we can find in a given population.

First, we check the ratio given.

The ratio is said to be that of left handed individuals to right handed individuals and this sits at 2 to 9.

Thus out of 1,320,000 people , the number of right handed individuals will be ;

9/(2+9) * 1,320,000

9/11 * 1,320,000

= 1,080,000 people

What does y=? Also if you cant read that bright red number its 60
Elena L [17]

Answer:

y = 13.9

Step-by-step explanation:

The triangle is a 30-60-90 triangle, so x is 16 (double 8). Use the pythagorean theorum to find y. 256 - 64 =192. \sqrt{192} is about 13.9

A rectangular garden has a perimeter of 48cm and an area of 140 sq. cm. what is the width of this garden
swat32
A) 2L + 2W = 48
B) L * W = 140
B) W = 140 / L
Inputting this to equation A)
A) 2L + 2*(140 /L) = 48
L + 140/L = 24
Multiplying both sides by "L"
L² + 140 = 24L
L² -24L +140 = 0
(L -10) * (L-14) = 0
L= 10
L = 14
If length = 10 then width =14
If length = 14 then width = 10

Evaluate the surface integral. S xz ds, s is the part of the plane 2x 2y z = 4 that lies in the first octant
maksim [4K]

The value of the given surface integral is 4.

The given plane intercepts the coordinate axes at (2, 0, 0), (0, 2, 0), and (4, 0, 0). These point are the coordinates of a triangular region that we can parameterize using.

S(u,v)=(1-u)((1-u)(2,0,0)+u(0,2,0)+u(4,0,0)\\S(u,v)=(2(1-u)(1-v),2u(1-v),4v)

<h3>What is the surface integral?</h3>

A surface integral is a generalization of multiple integrals to integration over surfaces. It can be thought of as the double integral analog of the line integral. Given a surface, one may integrate a scalar field over the surface or a vector field.

with 0≤u≤1 and  0≤v≤1. Then the surface element ds  is equivalent to

ds=\||\:\left(s_u\times \:\:S_v\right)||dudv=12\left(1-v\right)dudv

The surface integral is then

\int \:\int \:_Sxzds=12\int _0^1\:\int _0^1\:\left(2\left(1-u\right)\left(1-v\right),2u\left(1-v\right),4v\right)dvdu=4

Therefore the value of the given surface integral is 4.

PLZ HELP
Ludmilka [50]

Answer: No, 40 months isn’t reasonable.

Step-by-step explanation:

For Shellie: 40*3 = 120 cm in 40 months

For Carley: 40*2 = 80cm in 40 months

Next we add the amount of hair they have already to the amount of centimeters would grow.

Shellie: 120+10 = 130cm

Carley: 80+20 = 100cm

So if the girls wanted to cut their hair at the exact length, 40 months isn’t a reasonable solution.
