Given is -

The variables y and x have a proportional relationship, and y = 5 when x = 4.

\frac{y}{x}=\frac{5}{4}

As we have to find the value of x when y= 8 so putting y = 8 in the above relationship, we get :

\frac{8}{x}=\frac{5}{4}

5x=32

x=6.4

Hence, the answer is 6.4

Which describes the graph of fx=[x]-2 on [0, 3)?
marissa [1.9K]

Answer:

Step-by-step explanation:

Find the absolute value vertex. In this case, the vertex for  

y = |x − 2 | + 1 is  ( 2 , 1 ) .

To find the  x  coordinate of the vertex, set the inside of the absolute value  

x − 2  equal to  0 . In this case,  

x − 2 = 0. x−2 = 0

Add  2  to both sides of the equation.

x = 2

Replace the variable  x  with  2  in the expression.

y = | ( 2 ) − 2 | + 1

Simplify  

| ( 2 ) − 2 | + 1 .

Simplify each term.

Subtract  2  from  2

y = | 0 | + 1

The absolute value is the distance between a number and zero. The distance between  0  and  0  is  0 .

y = 0 + 1

Add  0  and  1 .

y = 1

The absolute value vertex is  ( 2 , 1 ) . ( 2 , 1 )

Firlakuza [10]

Step-by-step explanation:

a(n+y) = 10t + 32

n+ y = (10t + 32)/a

y = ((10t+32) /a) -n

Rebecca bought candy boxes in the shape of a square pyramid to use for party favors. The side length of each box is 3.6 inches,
diamong [38]

Answer:

Yes maybe.

Step-by-step explanation:

Well basically if we find the volume of 20 pieces of candy in all, that would be= 20*0.8= 16 cu.inches

And then if we find the volume of the square based pyramid, that would certainly be= 3.6*3.6*4 that is 51.84

Then lastly, if we do, 51.84 ÷16 the final answer will be 3.24. Which might actually be the answer as the pieces of candy certainly can't pass the limit 20 according to me.
