Answer:

2/9

Step-by-step explanation:

Total outcome = 36

Sum of 7 = 6

Prob of sum of 7 = 6/36

Sum of 11 = 2

Prob of sum of 11 = 2/36

Prob of sum of 7 or 11 = 6/36+2/36

Prob of sum of 7 or 11 = (6+2)/36

Prob of sum of 7 or 11 = 8/36 = 2/9

256 are needed because 32x1=32 that means the ratio would be 32:256 because 8 x 32 = 256
The final ratio would stay the same as 1:8 though because it would be simplified.
Hope this helped.

Angle n and angle p are linear pairs, and angle n is 10 more than twice the measure of angle p. Determine the measure of angle p
frutty [35]

Answer:

p = 56.7°

n = 123.3°

Step-by-step explanation:

The sum of linear pair angles is 180° because, because a linear pair angles, are angles formed by two intersected lines and the angle of a straight line is 180°.

Then your first equation is:

n + p = 180°

The second equation can be formulated with the information given:

"angle n is 10 more than twice the measure of angle p."

n = 10 + 2p

Replacing in the first equation:

10 + 2p + p = 180°

3p = 170°

p = 56.7°

n = 123.3°

Elanso [62]

Answer:

Step-by-step explanation:

Deal #1: One pizza= $8.99  

Deal #2: One pizza= $6.00  

Deal #1: Two pizzas= $13.99  

Deal #2: Two pizzas= $12.00  

Deal #1: Three pizzas= $18.99  

Deal #2: Three pizzas= $18.00  

Deal #1: Four pizzas= $23.99  

Deal #2: Four pizzas= $24.00  

Therefore, after FOUR pizzas, deal #1 becomes a better deal.  

Tip: Practice some math. You should be able to answer something like this within two minutes MAXIMUM.

Rate of change y=5x+10
frozen [14]

Answer:

5

Step-by-step explanation:

The equation y=5x+10 is given in slope-intercept form. Slope-intercept form is a way of writing the equation of a line in the format y=mx+b, such that the coefficient of the parameter (x) is the slope, and constant (b) is the y-intercept. What that essentially means is,

y = mx + b\\\\m=slope\\b = y-intercept.

The slope of a line is its rate of change, and the y-intercept is where the graph of the line intersects the y-axis. One can apply this knowledge here by saying that, the equation y=5x+10 is given in the slope-intercept form, and the coefficient (m) equals (5), therefore the slope is (5).
