Since you're told that the airfare cost is 737 we know that this is a number that will not be varied in any way and that this number will be added to the number of nights that he pays for to stay at a hotel. We are also told that the cost per night is 164 and that x represents the number of nights that he stays. We can then have the following

y = 164x + 737

for the second package we are told that it cost 249 for the round trip and 531 per night at a hotel. Moreover, once again x represents the number of nights that he will be staying at the hotel, giving the equation

y = 531x + 249

therefore, option C is the correct answer.

Match the formula to the correct figure.
ss7ja [257]
It is asking you to move the right formula with its match.

Formula for a cylinder: π*R^2*H
So the first option goes to the first shape.

Example: 
Radius=5
Length=10
π≈3.14
3.14*5²*10
=725 cm³ for the answer. 

Formula for a square: l*w*h

So the 4th option goes with the 2nd shape. 

Example: l=5 w=5 h=5
(Length * Width * Hieght) 

5*5*5=125 for the answer.

Formula for a cone is: 1/3π*r^2*h
So the second option goes to the 3rd shape. 

Example: r=3 h=11 
π≈3.14
\frac{1}{3} *3 ^{2} *11=33
33 is your answer. 

Formula for the pyramid would be: 1/3*b*h
So the 3rd option would go to the 4th shape.

Example: 
b=2 h=10
\frac{1}{3} *2*10=6.666667
Rounded: 6.6

Hope this helps!~

Please help me with my math
Taya2010 [7]
3x + 22 is the equation that represents the perimeter of the triangle.  4x + 10 is the perimeter of the rectangle.  Setting the two equal:

3x + 22 = 4x + 10

and collecting like terms:

x=11

We find that the perimeter of both shapes is equal to 11 units.

lorasvet [3.4K]
If you take the numerator and the denominator from flour and multiply both by 10, you'll get 40/100. then, add 40/100 to 12/100. your answer should be 52/100. if not, look back through your math. hope that helped.

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 7.5 parts
DochEvi [55]

Answer:

We accept  H₀   with the information we have, we can say level of ozone is under the major limit

Step-by-step explanation:

Normal Distribution

population mean  =   μ₀   =  7.5   ppm

Sample size     n   =  16      df  =  n  -  1  df  =  15

Sample mean      =    μ   =  7.8  ppm

Sample standard deviation   =  s  =  0.8

We want to find out if ozono level, is above normal level that is bigger than 7.5

1.- Hypothesis Test

null hypothesis                          H₀         μ₀   =  7.5

alternative hypothesis             Hₐ          μ₀  >  7.5  

2.-Significance level    α  =  0.01   we will develop one tail-test (right)

then   for   df  =  15    and    α =  0,01   from t -student table we get

t(c)  = 2.624

3.-Compute  t(s)

t(s)  =  (  μ -  μ₀ ) / s /√n            ⇒   t(s)  = ( 7.8  -  7.5 )*4/0.8

t(s)  = 0.3*4/0.8

t(s)  = 1.5

4.-Compare   t(s)   and  t(c)

t(s)  <  t(c)       1.5  <  2.64

Then  t(s) is inside the acceptance region. We accept  H₀
