Answer:
because as the number gets smaller the decimal moves more to the left
Step-by-step explanation:
If the number was to get bigger the decimal would go to the right

which represents an even function?
y=cos(x)
I think the one that represents a even function is cos(x)
Answer:
The cosine is an even function which means that if (x,y) is on the graph of the function so too is the point (-x,y). Since y corresponds to cos(x) then this means that cos(-x) = cos(x).

what fractions of the second ten counting numbers (11,12,13...,.18,19,20) Are composite and prime
will be the brainest
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
Which expression uses the commutative property to make it easier to evaluate 3/5·1/4·25
A.25·4·3/5
B.5/3·25·1/4
C.3\5·25·1\4
D.3/5·1/25·1/4
Answer:
C
Step-by-step explanation:
The expression that uses the commutative property is 3/5 × 25 × 1/4
What is the commutative property?The commutative property is a math rule that says that the order in which we multiply numbers does not change the product.
Given is an expression 3/5 × 1/4 × 25
We know that,
The commutative property of multiplication states that:
A × B × C = B × C × A
Using the above equation, we have the result of the commutative property to be:
3/5 × 1/4 × 25 = 3/5 × 25 × 1/4
Hence, the expression that uses the commutative property is 3/5 × 25 × 1/4

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.
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

A circular fountain has 132 feet of railing around it. What is the area of the fountain to the nearest square foot? Use 3.14 for π. *
Answer:
139
Step-by-step explanation:
First we need to find diameter 132/3.14=42 rounded
Then we halve it to find radius 42/2=21
Formula for area is radius x radius x 3.14
21 x 21 = 441 x 3.14 = 138.74 round up is 139
Answer:
18.8 feet, 59.1 feet to the nearest tenth
Step-by-step explanation:
The diameter is the line drawn that divides the circle into two while the circumference is the perimeter of the circle. Both are a measure of the radius of the circle.
The diameter D = 2r where r is the radius of the circle
The circumference = 2Πr = ΠD where Π = 22/7
Given that the circular fountain has a radius of 9.4 feet
Its diameter = 2 × 9.4 feet = 18.8 feet
The circumference = 22/7 × 18.8 feet
=59.09 feet
≈ 59.1 feet to the nearest tenth

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.

Answer:
2 3/8
Step-by-step explanation:
-7 1/8 = -(7*8 + 1) / 8 = -57/8
-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)
= 2 3/8

A bakery made 9 cakes using 3 bags of flour. The bakery uses the same relationship between cakes made and the amount of flour used to make all of their cakes. Which table of values shows the relationship between the number of cakes the bakery makes to the number of bags of flours the bakery uses?
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.
