If a length of a square is 3.2 cm square what is the perimeter and area

1 answer:

3 0

Since all of a squares sides are the same length, we can use 3.2 cm in the following equations:

P= 2L + 2W and A= L x W

P= 2(3.2) + 2(3.2) which is the same as P= 4(3.2)

P= 12.8 cm

A= 3.2 x 3.2
A= 10.24 cm^2

Describe the number of solutions for each system of equations graphed<br> below

abruzzese [7]

The solution of the system of equations means that following:
1- In case we are dealing with system of equations, the solution would be the point of intersection of the two graphs
2- In case we're dealing with only one equation, the solution would be the points of intersection of the graph with the x-axis

Graph (a):
The graph is for a system of equations (two lines). Therefore, the solution would be the point of intersection of the two lines.
From the graph, we can note that there is only one point of intersection between the two lines (-3,-1). Therefore, the system of equations has only one solution

Graph (b):
The graph is for a system of equations (two lines). Therefore, the solution would be the point of intersection of the two lines.
From the graph, we can note that the two lines are parallel. This means that they will never intersect. Therefore, the system of equations has no solutions

Graph (c):
The graph is for a single line. Therefore, the solution(s) would be the point(s) that make the overall equation equal to zero, i.e. point(s) of intersection with the x-axis.
From the graph, we can note that the line intersects with the x-axis only once at point (2,0). This means that the line has only one solution.

Hope this helps :)

Answer:

The cost of labor per hour is $105.

The expression is 4x + 77 = 497

Step-by-step explanation:

The expression is 4x + 77 = 497, where 4x represents the cost of labor per hour, 77 is the cost of the parts, and 497 is the total.

4x + 77 = 497

4x + 77 - 77 = 497 -77

4x = 420

4x/4=420/4

x = 105

Which answer correct estimates the product of 3.09 × 304.87

miv72 [106K]

The answer is 942.05. You get it by multiplying the two numbers together which should give you the product of 942.0483, since the 0 is not the number 5 or more ( which is the rule to round to a higher number) then you go to the hundredths place value which will be underlined for you... 942.0<u>4</u>83 and look to the right and since 8 is higher than 5, you change the four to a five, thus giving you your answer 942.05
