P=2(L+W)
100≥P

L is 4 times W
L=4W
sub 4W for L

100≥2(4W+W)
100≥2(5W)
100≥10W
divide both sides by 10
10≥W

the greatest possible width is 10cm

What is the relation between the variables in the equation x^4/y=7?

makkiz [27]

Answer:

So, the relation between variables are

$y=\frac{x^4}{7}$

Step-by-step explanation:

We are given

$\frac{x^4}{y}=7$

Since, we have to find relation between variables

so, we can solve for y

$\frac{x^4}{y}=7$

Firstly, we will multiply both sides by y

$\frac{x^4}{y}\times y=7\times y$

we can simplify it

$x^4=7\times y$

we can isolate y

so, we can divide both sides by 7

so, we get

$y=\frac{x^4}{7}$

In a certain region, the number of children who have been vaccinated against rubella is twice the number who have been vaccinate

MatroZZZ [7]

Answer:

C. 10 000

Step-by-step explanation:

If we called:

x = children who have been vacinated against rubella only

2x = children who have been vaccinated against mumps

y = children who have been vaccinated agains both

Children who have been vaccinated against mumps only = x - y

And we know that y = 2*(x-y)

=> 2y = 3x

y = 5000

There fore x = 7500

The number of children who have been vaccinated against rubella

= 2x - y = 2*7500 - 5000 = 15 000 - 5000 = 10 000

An olympic hurdler accelerates at a rate of 15.5 m/s2 . what is the rate in miles/min2 ? 1. 6.89 miles/min2 2. 31.8 miles/min2 3

Tom [10]

For this case we have to take into account the following conversions:
$1 mile = 1609.34 meters

1 minute = 60 seconds$
Let's first transform the expression to miles per seconds squared:
$(15.5) * (1 / 1609.34) = 0.009631277 mi / s ^ 2
$
Then, we transform the result to miles per minute squared.
We have then:
$(0.009631277) * (60) ^ 2 = 34.7 mi / min ^ 2
$
Answer:
the rate in miles/min^2 is:
$34.7 mi / min ^ 2$
