1 answer:
Kipish [7]3 years ago
6 0

Answer:

y = 39

Step-by-step explanation:

550 x \pi = \pi r^{2} x 11 + y

550 x \frac{7}{22} = \frac{7}{22} x 11 x 11 + y

550 x \frac{7}{22} x \frac{22}{7} = 11 x 11 + y

550 = 11 x 11 + y

\frac{550}{11} = \frac{11}{11} x 11 + y

50 = 11 + y

50 - 11 = y

39 = y

Select the correct inequality for the graph given
Kaylis [27]

Answer:

y<= 3x-1

Step-by-step explanation:

When it comes about inequalities, keep in mind the following

the < sign means that the regions is under whatever is to other side, and the > means that the region is above whatever is on the other side of the sign

So, we see for the graphic that there is a region below a line, this suggests us that there is a < sign implied

The other thing is that there is a convention in math, is the line is graphed using a dashed line, it meas that it is not part of the region, if the line is graphed using a solid line (a continued line) then the line is inside the region, hence there is a = sign implied.

So the answer is y<= 3x-1

describe the relationship between n and 4 that will make the value of the expression 7× n/4 greater than 7
Norma-Jean [14]
So set up an equation!

7* n/4 > 7

So trying to get the variable alone...

n/4 > (7/7) aka 1
n> 1*4
n> 4

Try it out!

7* 6/4 = 42/4 = 21/2= 10 and 1/2

It is greater than 7
