Is 16.4 greater than 16
Answers
Answer:
yea
Step-by-step explanation:
Yes.
16 could also be written as 16.0, or 16.00 or even 16.00000.
16.4 could also be written as 16.40, or 16.400.
And of course, you know 4 is greater than 0.
This is why 16.4 is greater.
When you add a decimal to a number, it always makes it larger. its like saying 16 and 4 tenths.
An insect population is growing at a rate of 2t/8 insects per day. Find the size of the insect population after 24 days assuming that there are 100 insects at time t=0.
Answers
Answer:
244
Step-by-step explanation:
Number of insects at time [tex]t[/tex] = 0 are 100.
Rate of growth of insects = [tex]\frac{2t}8[/tex] insects per day
Time, Number of days = 24 days
To find:
Number of insects or size of insect population after 24 days.
Solution:
Given that rate of growth of insects = [tex]\frac{2t}8[/tex] insects per day
We are given that, [tex]t[/tex] = 24 days
Rate of growth =
[tex]\dfrac{2\times 24}{8} = 2\times 3 = 6[/tex]
Growth in Insect population after 24 days = [tex]24\times 6 = 144[/tex]
Initial population = 100
Therefore, the answer is:
The size of insect population after 24 days = 100 + 144 = 244

Answers
Answer:
c = 3b
Step-by-step explanation:
9 cakes proportional to 3 bags of flower
cake = k(bag)
c = kb
9 = k(3)
k = 3
c = 3b
you didn't send any table of values but this is the relationship between the cakes and flour, you can use it.

x+ y + z = -3

Answer:
(-3, 1, -1)Step-by-step explanation:
x + y + z = -3 --> (1) 3y - z = 4 --> (2)2x - y - 2z = -5 --> (3)Add up (1) and (2)
x + 3y + y + z - z = -3 + 4 ⇒ x + 4y = 1 --> (4)Double (2) and subtract from (3)
2x - y - 2z - 2(3y - z) = -5 - 2(4) ⇒ 2x - y - 2z - 6y + 2z = -5 - 82x - 7y = -13 --> (5)Double (4) and subtract (5)
2(x + 4y) - 2x + 7y = 2 + 13 ⇒ 2x + 8y - 2x + 7y = 15 ⇒ 15y = 15 ⇒ y = 1Finding x
x + 4(1) = 1 ⇒ x = 1 - 4 ⇒ x = -3Finding z
-3 + 1 + z = -3 ⇒ z = -1So the answer is:

what fractions of the second ten counting numbers (11,12,13...,.18,19,20) Are composite and prime
will be the brainest
Answers
Answer:
Fraction of composite numbers = 6/10
Fraction of prime numbers = 4/10
Step-by-step explanation:
A composite number can be defined as a positive integer that will be formed when we multiply two smaller positive integers. It can also be said to be a positive integer that has at least one divisor of which 1 and itself are not included.
Thus, it means that the set of numbers given to us which is;
(11, 12, 13, 14, 15, 16, 17, 18, 19, 20), the composite numbers are;
12, 14, 15, 16, 18, 20
This is because each of them have at least one divisor that is neither itself or 1.
Thus, we have 6 out of the 10 numbers as composite.
Fraction of composite numbers = 6/10
Now, a prime number is a number that are only divisible by itself and 1.
Thus,from the given set, the prime numbers are; 11, 13, 17 & 19
We have 4 out of 10 numbers as prime numbers.
Thus, fraction of prime numbers = 4/10

-9 1/2 = - (9*2 + 1) / 2 = - 19/2
simplifying
= -57/8 - (-19/2)
= -57/8 + 19/2
= lcm of 2 ,8 is 8
= (-57 + 4*19) / 8
= (-57 + 76) / 8
= 19 / 8 ------> (19 = 8*2 + 3)

If there were 80 points scored overall, how many of them were scored by Bridgette? she scored 5% of the points
Answers
Answer: she scored 4 points
Step-by-step explanation: 5% of 80=4
;-----------;
Answer:
4 points were scored by bridgette
Step-by-step explanation:
80 times 5 equal 400
Then you move the decimal point to the left by the number of digits the whole number has. In this case, it only has 2, so we move the decimal point 2 spaces over to the left.. Therefore, 400 becomes 4.00. 4.00 is the same as 4, so 4 is your answer.

Write down in terms of n, an expression for the nth term
of the following sequences
a) 25 20 15 10 5
Answers
Answer:
Solution,
First term (a) = 25
Common difference (d) = Second term - first term = 20 - 25 = -5
Now,
nth term = a + (n - 1)d = 25 + (n - 1) (-5) = 25 - 5n +5 = 30 - 5n
The nth term of the series is 30 - 5n
Answer:
The nth term will be:
[tex]a_n=-5n+30[/tex]
Step-by-step explanation:
Given the sequence
25, 20, 15, 10, 5
An Arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
Computing the common difference of all the adjacent terms
[tex]25,\:20,\:15,\:10,\:5[/tex]
[tex]20-25=-5,\:\quad \:15-20=-5,\:\quad \:10-15=-5,\:\quad \:5-10=-5[/tex]
As the difference between all the adjacent terms is the same and equal to
[tex]d=-5[/tex]
Also, the first term is:
[tex]a_1=25[/tex]
Hence, the nth term will be:
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_n=-5\left(n-1\right)+25[/tex] ∵ [tex]a_1=25[/tex], [tex]d=-5[/tex]
[tex]a_n=-5n+30[/tex]
Therefore, the nth term will be:
[tex]a_n=-5n+30[/tex]

The Equation of parallel line is y= 3/7 x - 2/7.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
We have equation 3x – 4y = 7 and passes through (-4, -2).
Writing the given equation in slope intercept form as
3x = 7 +4y
4y = 3x- 7
y= 3/7 x - 4/7
so, the slope of parallel line is 3/7.
and, passes through (-4, -2).
y= 3/7 x +b
-2 = 3/7(-4) +b
-2 = -12 /7 + b
b = -2/7
So, the Equation of line is y= 3/7 x - 2/7.
