Answer:
The number 10/2 = 5 is an integer.
Step-by-step explanation:
An integer is a whole number which cannot be expressed in fractions. For example, 1, 2, 3...
Integer can be positive, negative of zero.
It is a whole number so it is an integer.
- 0.3
It is not an integer as it has a fractional part.
It also has a fractional part, so it is not an integer.
0.4
It also has a fractional part, so it is not an integer.
First one
20=n/5+10
minus 10 both sides
10=n/5
times 5 both sides
50=n
2.
hmm
expand
p(x)=2x^2+5x+3-3x-3n
p(x)=2x^2+2x+3-3n
it looks like the coefients of the x terms are divisble by 2
because
if we have
p(x)=2(something)
the p(x) is divisible by 2
therefor that factor is 2 or -2
find what value of n works
so
3-3n=a multipule of 2
we are given
-3,-2,0,2
try each
3-3(-3)=3+9=12, that's divisble by 2
3-3(-2)=3+6=9, that's not divisible by 2
3-3(0)=3, that's not divisble by 2
3-3(2)=3-6=3, that's not divisble by 2
the onnly one that woks is when n=-3
answer is A
Answer:
question 20 ) 19.1 feet
question 21) 24 clips
Step-by-step explanation:
<h2><u>Question 20:</u></h2><h3><u>Circumference of a circle </u></h3>
formula:
therefore we can find the radius (r) , also include the circumference of 60 feet.
where
2 * 3.14 * r = 60
r =
r = 9.554....
<h3>to find the diameter we can use the formula :</h3>
<em>diameter = radius * 2</em>
diameter = 9.554 * 2
diameter = 19.108
to 3 sf
<h3><u>diameter = 19.1 feet </u></h3>
<u />
<h2><u>Question 21</u></h2>
large binder clips each cost $ 1.50
amount for purchases is $ 36.00
therefore the number of clips bought can be regarded as (x)
the formula would be :
1.50 * x = 36
x = 36/1.5
<u>x = 24</u>
<u></u>
<h3><u>hence the mom bought 24 binder clips</u></h3>
Answer:
