Answer:
104.364
Step-by-step explanation:
Product means multiplication so:
44.6×2.34 = 104.364
Answer: to minimize the effects of variables other than the independent variable (i.e. confounding variables)
Step-by-step explanation:
A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable (i.e. confounding variables). This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
Step-by-step explanation:
Bringing like terms on one side
a2 - 2 = - 8a + 7a
a2 - 2 = - a
a2 + a - 2
a2 +2a - a - 2
a(a + 2) - 1 (a + 2)
(a + 2) and (a - 1)are the factors
Answer:
Length of 6 feet
Width of 2 feet
The estimate of the perimeter of the countertop is 16 feet.
Step-by-step explanation:
Rectangle:
A rectangle has two dimensions: The length(l) and the width(w). The perimeter of a rectange is:
P = 2(l + w).
In this question:
Length: 5.75 feet
Width: 2.47 feet.
Round the length and width to the nearest whole number .
5.75 is closer to 6(0.25) than to 5(0.75). So the length is 6 feet.
2.47 is closer to 2(0.47) than to 3(0.53). So the width is 2 feet.
Then estimate the perimeter of the countertop
P = 2(l + w) = 2(6 + 2) = 16
The estimate of the perimeter of the countertop is 16 feet.
