Let i = sqrt(-1) which is the conventional notation to set up an imaginary number
The idea is to break up the radicand, aka stuff under the square root, to simplify
sqrt(-8) = sqrt(-1*4*2)
sqrt(-8) = sqrt(-1)*sqrt(4)*sqrt(2)
sqrt(-8) = i*2*sqrt(2)
sqrt(-8) = 2i*sqrt(2)
<h3>Answer is choice A</h3>
Answer:
Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7
Step-by-step explanation:
-1.7 + (-6.3)
Correct simplification
-1.7 + (-6.3)
Open parenthesis
= - 1.7 - 6.3
= -8
NOTE:
- * + = -
- * - = +
+ * - = -
+ * + = +
Maureen's simplification
-1.7 + (-6.3)
= 1.7 - 6.3
= -4.6
Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7
Answer: positive
Step-by-step explanation:
Answer:
28 pages in 1 day
Step-by-step explanation
you have to find the unit rate of pages to days, the number of days must be 1.
to find the amount of pages, you find 924/33, which equals 28.
a = 28
b = 1
Answer: 153 trays
Step-by-step explanation:
hotdogs =153
Hamburger = 171
Mike is to put the same number of hamburger and hotdogs in each plate.
we assume that a whole number of each food is placed in each tray.
The maximum amount of trays will be determined by the minimum food which is hotdog, so, the hotdog is the constraint.
Mike will have to use 153 trays.
