since there are 6 faces on a die there is a 3/6 or 1/2 chance of rolling a die and getting a prime number.

Troyanec [42]

I would say 2/5 chance since 1 is neither prime or composite

If sv=38, su=26, and the perimeter of SUV is 102, what is the value of RU?

Finger [1]

Answer:

38

Step-by-step explanation:

Let SUV be a triangle

Perimeter of SUV = SU+SV + UV

102 = 38 + 26 + UV

102 = 64 + UV

UV = 102 - 64

UV = 38

Hence the length of UV is 38

Write the slope intercept form of the r question of the line parallel to the graph of 2x+y=5 that passes through (0,1)

Fofino [41]

Step-by-step explanation:

first let's get the original line in slope intercept form.

the vegetal slope intercept form is

y = ax + b

a is the slope, b is the y-intercept.

2x + y = 5

y = -2x + 5

there !

a line parallel to this line must have the same slope (-2).

but it will intersect with the y-axis at a different point.

the y-intersect is the y value when x = 0.

the given point (0, 1) is already that y-intersect (because x=0).

so, the desired parallel line function is

y = -2x + 1

if we had a different point of the line, e.g. (4, -7), we would go back to the general equation

y = ax + b

put in the slope we know (-2)

y = -2x + b

and then put in the x and y cakes if the point and calculate b

-7 = -2×4 + b

-7 = -8 + b

b = 1

and then we get again

y = -2x + 1

Find the constant of proportionality for the table of values and write in the form y = kx

sveta [45]

Answer:

Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Number of lemons used is denoted by 'y'.

Number of glasses of lemonade is denoted by 'x'.

As we can observe that ,

$\frac{6}{24} = \frac{8}{32} = \frac{7}{28} = \frac{2}{8} = \frac{4}{16} = \frac{1}{4} \\$

so we can write i as

$\frac{x}{y} = \frac{1}{4}$

By cross multiplication

<em>y=4x</em>

So, if write it in the form y=kx,

It will be y=4x.
