Answer:
8
Step-by-step explanation:
S= 2LW + 2LH + 2WH
solve for W
Rewrite the equation as
2lw+2lh+2wh=a.2lw+2lh+2wh=a
Subtract
2lh
from both sides of the equation.
2lw+2wh=a−2lh
Factor
2w out of 2lw+2wh.
2w(|+h)=w−2lh
Divide each term by
2(l+h)
and simplify.
.w=a−2lh2(l+h)

At a recent meeting at the American College of Asthma, Allergy, and Immunology, researchers reported that allergy vaccinations are effective in treating sinusitis (inflammation of the membrane lining the facial sinuses) in individuals predisposed to allergies. Specifically, the researchers reported that of individuals predisposed to allergies find relief from their sinusitis after allergy vaccinations. Suppose that this number is accurate and that individuals predisposed to allergies are chosen at random and given allergy vaccinations.
a. Estimate the number of individuals in the random sample who do not find relief from their sinusitis by giving the mean of the relevant distribution (that is, the expectation of the relevant random variable).
b. Quantify the uncertainty of your estimate by giving the standard deviation of the distribution.

Answer:
31 2/3
Step-by-step explanation:
No doubt you have been shown at least a couple of different strategies for multiplying mixed numbers.
1) Use the distributive property.
10(3 1/6) = 10(3) +10(1/6) = 30 +10/6 = 30 +5/3 = 30 + 1 2/3 = 31 2/3

2) Use improper fractions.
10(3 1/6) = 10(19/6) = 190/6 = 95/3 = 31 2/3

What is the algebraic inverse of the function? f(x) = 2x -6 please include steps
9514 1404 393
Answer:
f^-1(x) = (x +6)/2
Step-by-step explanation:
The inverse function is found by solving ...
x = f(y)
Here that is the solution to ...
x = 2y -6
x +6 = 2y . . . . . add 6
(x +6)/2 = y . . . divide by the coefficient of y
The inverse function is ...
f^-1(x) = (x +6)/2
To rent a certain meeting room, a college charges a reservation fee of $13 and an additional fee of $5 per hour. The chemistry club wants to spend less than
$43 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room?
Use t for the number of hours.
Write your answer as an inequality solved for t.
Answer:
2 hours or lower
Step-by-step explanation:
$13 + $5t = fee
13 + 15t = 43 --> minus 13 on both sides
15t = 30 --> divide by 15 on both sides
t = 2
Answer: t=6
Explanation:
They want to spend less than $43, 43-13=30 and 30/5=6, Therefore they could have 6 hours max, if the initial reservation fee is $13 and and additional $5 per hour.
A function f is defined by f(x) = 3x + 1. Find
a. f(0)=
c. f(2)=
F(-2)
Answer:
a) f(0)=3*0+1 =0+1= 1
b)f(2)=3*2+1=6+1=7
c)f(-2)=3*(-2)+1=-6+1=-5
Answer:
Step-by-step explanation:
f(x) = 3x+1
f(0) = 3x + 1
f(0) = 3*0+1
f(0) = 0+1
f(0) = 1
f(2) = 3x+1
f(2) = 3*2+1
f(2) = 6+1
f(2) = 7
f(-2) =3x+1
f(-2) =3*-2+1
f(-2) = -6+1
f(-2) = -5
f(-2) =
Entrance to a state park costs $6 per car, plus $2 per person in the vehicle. How might you determine the entrance cost for a bus with 50 people?
Answer: 130 dollars because 26 times 5 is 130 and 5 stands for 50 people
Assuming each family had one car, 2 people would cost $10, 4 would cost $14, 10 would cost $26.

X=
Similar triangles may or may not be congruent
The value of x that makes both triangles similar is 4.5
The equivalent ratio of both triangles is:
[tex]\mathbf{2 : 1 = 9 : x}[/tex]
Express the above equivalent ratio as a fraction
[tex]\mathbf{\frac 12= \frac x9 }[/tex]
Multiply both sides of the fraction by 9
[tex]\mathbf{\frac 12\times 9 = \frac x9 \times 9 }[/tex]
Cancel out common factors
[tex]\mathbf{\frac 12\times 9 = x}[/tex]
Divide 12 by 9
[tex]\mathbf{4.5 = x}[/tex]
Rewrite the above expression as:
