Answer:
Step-by-step explanation:
The protractor has inner and outer readings. The inner reading has graduations with intervals of 10 degrees and the outer reading also has graduations with intervals of 10 degree. We will use the outer graduations to take readings. On the outer reading, the shortest graduations is in intervals of 1 degree while the shorter graduation is in intervals of 5 degrees. Therefore,
a) angle AFB is 55 degrees
b) angle BFE is 180 - 55 = 125 degrees.
c) angle DFA is 126 degrees
d) angle BFD is 60 + 5 + 6 = 71 degrees.
e) angle CFD is 36 degrees
Answer:
$7.68
Step-by-step explanation:
You must find the rate first, so in order to do that you divide the price by the quantity which is
3.20/5
which equals .64 and this number is the cost of potatoes per pound so to find 12 pounds you do
.64 * 12
which equals 7.68
Answer:
(x + 2)(x + 2)(2 - x), or (x + 2)^2(2-x)
Step-by-step explanation:
Find the LCD of the following fractions:
7 5
------------------ , ---------------
x^2 + 4x + 4 4 - x^2
To do this, factor both denominators, obtaining:
7 5
------------------ , -----------------
(x + 2)^2 (2-x)(2+x)
These two denominators have one factor in common: x + 2.
The LCD is the product of this common factor and each of the non-common factors:
(x + 2)(x + 2)(2 - x), or (x + 2)^2(2-x)
