Find the total square footage of each room. The room will be a rectangle and finding the area of a rectangle is just the length times the width
area of rectangle = lw
area of each room = 14 x 20.5 = 287 ft^2
The 4 rooms each have the same square footage.
Total square footage of all rooms = 287 x 4 = 1148 ft^2
To find how many roles of carpet are needed, divide the footage needed to be covered by the footage per carpet
1148/200 = 5.74
You can't buy 5.74 of a carpet roll, so you will need 6 rolls :)
Hope I helped
Answer:
B
Step-by-step explanation:
Answer:
a) (-5,0) and (1,0)
b) (0,-5)
c) minimum
See attached graph.
Step-by-step explanation:
To graph the function, find the vertex of the function find (-b/2a, f(-b/2a)). Substitute b = 4 and a = 1.
-4/2(1) = -4/2 = -2
f(-2) = (-2)^2 + 4(-2) - 5 = 4 - 8 - 5 = -4 - 5 = -9
Plot the point (-2,-9). Then two points two points on either side like x = -1 and x = -3. Substitute x = -1 and x = -3
f(-1) = (-1)^2 + 4 (-1) - 5 = 1 - 4 - 5 = -8
Plot the point (-1,-8).
f(-3) = (-3)^2 + 4(-3) - 5 = 9 - 12 - 5 = -8
Plot the point (-3,-8).
See the attached graph.
The features of the graph are:
a) (-5,0) and (1,0)
b) (0,-5)
c) minimum
This is an equation of a parabola that opens upwards.
Answer:
<u>The missing side is 12 cm length</u>
Step-by-step explanation:
1. Let's review the information given to us to solve the case correctly:
Length of the longest side= 13 cm
Length of one leg = 5 cm
2. Using the Pythagorean theorem for finding the length of the second leg, because this is a right triangle:
2nd leg² = Length of the longest side ² - Length of one leg²
2nd leg² = 13 ² - 5 ²
2nd leg² = 169 -25
2nd leg² = 144
2nd leg = √144
2nd leg = 12 cm
<u>The missing side is 12 cm length</u>
