12. The thickness of a plywood is 11 mm.
(i) How many centimetres is this?
(ii) what part of a metre is mm
Answer:
I) 1.1cm
II) 0.001m = 1mm
Step-by-step explanation:
I)
10mm = 1 cm
11mm = ?
? = (11 x 1)/10 =11/10 =1.1
II)
1000mm = 1m
Milli represents 10^-3 = 0.001
1 millimeter = 1 x 0.001 =0.001m

State the number of complex zeros and the possible regional zeros for the function
Show steps
Answer:
D) 2 complex zeros; rational zeros among ±{1, 5, 7, 35}
Step-by-step explanation:
The signs of the coefficients of the polynomial are (+ + + +). They are all the same; there are 0 sign changes. When odd-degree terms change sign, the signs are (- + - +). There are 3 changes: -→+, +→-, -→+.
Descarte's Rule of Signs tells you the lack of sign changes among the coefficients means there are 0 positive real roots. When the signs of odd-degree terms are changed, there are then 3 sign changes, indicating 1 or 3 negative real roots and 2 or 0 complex roots.
There are possibly 2 complex roots.
__
The Rational Root Theorem tells you any possible rational roots will be divisors of the constant term, 35. Those divisors are ±1, ±5, ±7, ±35.
Possible rational roots are ±1, ±5, ±7, ±35.
_____
Additional comments
A graphing calculator shows the one rational root to be x=-5. The other two real roots are irrational (-3±√2). All are negative, as predicted.
__
Complex roots always come in conjugate pairs, so there will always be an even number of complex roots. This means an odd-degree polynomial will always have at least one (1) real root.
We can shorten the list of possible rational roots by remembering that there are 0 positive real roots. Then possible rational roots are -1, -5, -7, -35. In this problem, you're merely supposed to apply the rule, and not refine the result.
Changing the signs of odd-degree terms is equivalent to reflecting the function over the y-axis. That suddenly makes negative real roots into positive real roots, so the sign change rule can be applied as for positive real roots.

Which equation represents the relationship between the angles shown below?
Answer:
4x + 44 = 180
Step-by-step explanation:
4x = 180- 44
4x = 136
x= 136÷ 4
x= 34
Answer:
4x + 44 = 180
Step-by-step explanation:
sum of angles on a straight line = 180
4x + 44 = 180
subtract 44 from both sides
4x + 44 - 44 = 180 - 44
4x = 136
Divide both sides by the coeficient of x
4x = 136

x = 34

according to the department of agriculture consuming 100 grams of banana provides 0.15 milligrams of zinc which of the following is closest to the number of milligrams of zinc provided by 140 grams of banana?
A. 0.15
b. 0.21
C 0.25
D. 0.93
The answer is B how did they get that????
Answer:
x = 0.21
Step-by-step explanation:
[tex]\frac{.15}{100} = \frac{x}{140}[/tex]
.15(140) = 100x
21 = 100x
x = 0.21
The number of milligrams of zinc provided by 140 grams of banana will be 0.21 milligrams. Then the correct option is B.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
According to the department of agriculture consuming 100 grams of banana provides 0.15 milligrams of zinc.
Then the number of milligrams of zinc provided by 140 grams of banana will be given by the ratio.
Let x be the amount of zinc. Then the equation is given as,
x / 140 = 0.15 / 100
x / 1.4 = 0.15
x = 0.21 milligrams
The number of milligrams of zinc provided by 140 grams of banana will be 0.21 milligrams. Then the correct option is B.

Smallest zero 2/54) The length of a rectangle is double its width. Its perimeter is 33cm. How long is its
width?
5.5 cm
Step-by-step explanation:
Let x be the width of the rectangle.
Since the length is double the width, the length would be 2x.
x can be found by solving the perimeter equation. The perimeter of the rectangle can be found by the equation:
[tex]p = 2(l + w)[/tex]
[tex]33 = 2(2x + x)[/tex]
[tex]33 \div 2 = (2x + x)[/tex]
[tex]16.5 = 3x[/tex]
[tex]16.5 \div 3 = x[/tex]
[tex]5.5 = x[/tex]
Therefore, the width of the rectangle is 5.5 cm.

How many years is 10000 hours? [365 days = 1.0 year] *
There is 24 hours in a day. Therefore, there are 8760 hours in a 365-day calendar year (365 x 24 = 8760).
How many years is 10000 hours?
Take the total number of hours and divide it by the number of hours in a year.
10000/8760 = 1.1415
Therefore, 10000 hours is approximately 1.14 of a year.
