Answer:

48 plastic bandages.

Step-by-step explanation:

The ratio 3 to 9 entails that for every 3 fabric bandages there should be 9 plastic bandages. For 16 fabric bandages, there should be...

[tex]16 \: \times \: \frac{9}{3} \: = \: 16 \: \times \: 3 \: = \: 48[/tex]

... plastic bandages.

Step-by-step explanation:

The percent of change in the price of a cellphone from 2010

to today is 58.33%

The price of cellphone was $240 in 2010.

While the price of cellphone presently is $380.

The percent of change in the price of a cellphone from 2010  to today is:

Percent change in price = [(380 - 240)/240] * 100%

Percent change in price = 58.33%

Hence, The percent of change in the price of a cellphone from 2010

to today is 58.33%

Sorry i dont know but need the points

Step-by-step explanation:

Answer:

fg(x)=f(g(x)

=f(x-5)

But ;f(x)=x+2

f(x-5)=(x-5)+2

=x-5+2

fg =x-3

gf(x)=g(f(x))

=g(x+2)

But ;

g(x)=x-5

g(x+2)=(x+2)-5

=x+2-5

=x-3

g(g)=g(x-5)

g(x-5)=(x-5)-5

=x-5-5

=x-1

Step-by-step explanation:

divide 37 by 600 and you'll get 222

Answer:

Step-by-step explanation:

a.Changing f with -f does not change its domain, it just flips the image across the x axis. Adding 6 to the result, just shifts everything towards the positive y by 6 units. Domains stays the same, from -4 to +8. Range instead goes up, the lowest value is -2+6 = 4 and the highest value is 2+6 = 8.

So domain remains the same [-4; 8] and range goes to [4;8]

a. This time we're shifting everything on the horizontal axis, one unit to the left (the way to remember it is that f(x) has a minimum at x=4, while after the shift the new value happens at x=3) multiplying the value by 3 means that every value gets scaled up. It means the minimum becomes -2*3= -6 and the maximum happens at 2*3= 6. The shift brings the domain to [-5;7] and the range to [-6,6]

Answer: the slope is -1, and the y-intercept is 5.

Step-by-step explanation:

To find the slope and y-intercept, we change the equation to y = mx + b form, where m is the slope and b is the y-intercept.

3y + 3x = 15  (Minus 3x to both side)

        3y = -3x + 15  (Divide 3 from the both side, to get in term of y)

          y = - x + 5

Using y = mx + b form, in this case, the slope is -1, and the y-intercept is 5.

Step-by-step explanation:

Distance formula: (see attached file) pythogorean rule

is the squared coordinates x added to squared coordinates of y

X- coordinates: -5 & -9

Y- coordinates: -5 & -2

Substitute into equation:

[tex]distance = \sqrt{ ( - 5- - 9)^{2} + ( - 5 - - 2)^{2} } = 5[/tex]

Answer:

[tex]m=-1[/tex]

Step-by-step explanation:

Basically, the equation is written in a slope-intercept form which is

[tex]y=mx+b[/tex]

So we know that any variable that by its self always has a 1 in front of it

Meaning that the equation written with 1 would look like

[tex]y=-1x+4[/tex]

Step-by-step explanation:

25 = 50%

x = 30%

y = 20%

1% = 0.5 because 25/50= 0.5

0.5 x 30 = 15 and 0.5 x 20 = 10
