During the year 2013 approximately 7.07 x10 to the power of 9 pennies were minted (made by the U.S. Mint). In the year
2000 approximately 1.43x 10 to the power of 10 were minted. Estimate how many times more pennies were minted in the
year 2000 compared to the year 2013. Give a possible explanation for the decline.
Using proportions, it is found that 2.04 times more pennies were minted in the year 2000 compared to the year 2013.
What is a proportion?A proportion is a fraction of a total amount. From it, the amount of times a measure a is greater than a measure b is given by a divided by b.
In this problem:
In 2013, the quantity was of [tex]7.07 \times 10^9[/tex].In 2000, the quantity was of [tex]1.43 \times 10^{10}[/tex]Hence, 2.04 times more pennies were minted in the year 2000 compared to the year 2013.
Hence, applying the proportion:
[tex]\frac{1.43 \times 10^{10}}{7.07 \times 10^9} = \frac{14.3 \times 10^9}{7.07 \times 10^9} = 2.04[/tex]

find the missing side length
Answer:
n = 5
Step-by-step explanation:
it is stated that the two triangles are similar so we can use the similarity ratio to find the value of n:
RQ/BA = QR/AC
n/2 = 10/4 cross multiply expressions
4n = 20 divide both sides by 4

A. a slight negative charge on the oxygen B. a slight positive charge on the hydrogens C. the water molecules stick together because of their opposite charges D. some substances must dissolve into water to move into and out of a cell
The option (D) some substances must dissolve into water to move into and out of a cell is not a result of water being a polar molecule
How to determine the false option?The water molecules contains
Oxygen atomsHydrogen atomsThe oxygen atoms have a slight negative charge, while the hydrogen atoms have a slight positive charge.
Because of the opposite charges in water (i.e. negative charge in oxygen and positive charge in hydrogen), the water molecules stick and stay together.

Find the value of x for which ABCD must be a parallelogram.
Answer options:
5
3
17
34
Answer:
Opposite sides of the parallelogram are equal :
→ BC = AD
→ 5x - 8 = 2x + 7
→ 5x - 2x = 7 + 8
→ 3x = 15
→ x = 15/3
→ x = 5
Therefore, the value of x is 5.
can you put 2x-y=7 into y equals
Answer:
y = 2x - 7
Step-by-step explanation:
Step 1: Subtract 2x from both sides.
2x - y - 2x = 7 - 2x-y = -2x + 7Step 2: Divide both sides by -1.
-y/-1 = (-2x + 7)/-1y = 2x - 711) through: (-1, 2), slope = -1

A) x-2y=1
B) x + 2y = 1
C) 2x - y = 2 D) r + y = 1

Step-by-step explanation:
y-y1=m(x-x1)
y-2=-1(x-(-1))
y-2=-(x+1)
y=-x-1+2
y=-x+1
y-(-x)=1

Alex and James both have a bag of marbles.
* Alex's bag has 10 red marbles and 10 blue marbles.
James's bag has 15 red marbles, 10 blue marbles and 5 green marbles.
They each take a marble out of their bag without looking.
Select the statements that are correct:
-
A - They both have the same probability of picking a blue marble.
B - The probability of Alex picking a red marble is 50%.
C - They both have the same probability of picking a red marble.
D - The probability of James picking a green marble is 5%.
E - James has a higher chance of picking a red marble than Alex.
Answer:
[B] The probability of Alex picking a red marble is 50%.
[C] They both have the same probability of picking a red marble.
Step-by-step explanation:
Given;
Alex and James both have a bag of marbles.
Alex's bag has 10 red marbles and 10 blue marbles.
James's bag has 15 red marbles, 10 blue marbles and 5 green marbles.
They each take a marble out of their bag without looking.
Solve;
Alex have 10 Blue marbles so 10 out of 20 are Blue.
James has 10 Blue Marbles so 10 out of 30 are Blue.
Hence, [A] They both have the same probability of picking a blue marble.
is False.
Alex have 10 red and 10 blue which 10 = 10
thus, [B] The probability of Alex picking a red marble is 50%.
Alex's have 10 red marbles and James's have 15 red marbles.
10 out of 20 of them are red. Thus, that 50%
15 out of 30 of them are red. Thus, that 50%
50% = 50%
Hence, [C] They both have the same probability of picking a red marble.
is true.
James have 15 red, 10 Blue, 5 Green marbles.
15 + 10 + 5 =30 [ Total ]
5 out of 30 is Green
5/30 = 0.16666666666
Round = 16.67%
Hence, [D] The probability of James picking a green marble is 5%.
is False.
15 out of 30 and 10 out of 20
15/30 = 50% and 10/20 = 50%
Thus, [E] James has a higher chance of picking a red marble than Alex.
is False.

Piecewise function question please help!
Answer:
b
Step-by-step explanation:
We know we are trying to find an inverse function and the normal function of the first part would be (x+7)²-5, so we can eliminate all equations with an equation starting with (x+7)²-5. So, a and f are out of the scope.
The domain of the inverse function will be the range of the normal function.
So, the range of the first part of the inverse function is -5 < x < -3 which is the domain of the normal function. Now, we can eliminate c, d, and e.
Our answer must be b.
=====================================================
Explanation:
The endpoint (-7,-5) reflects over the line y = x when forming the inverse. It will reflect to (-5,-7). The x and y coordinates swap.
The new point (-5,-7) forms the vertex of a piece of a parabola. Since it's the vertex, we have something of the form y = a(x+5)^2 - 7 which matches with choices B and D.
However, we can rule out choice D because the interval is not x < -3. Try out a point like x = -100 and it will make x < -3 true, but -100 is definitely not part of the reflected parabola formed. Instead, we must have -5 < x < -3 as the domain of the inverse.
Notice how the range of the square root portion on the left is -5 < y < -3. The range of the original function forms the domain of the inverse, and vice versa. Effectively, all we're doing is replacing y with x when going from -5 < y < -3 to -5 < x < -3.
--------------
Also another reason we can rule out choice D is to see that something like x = -2.5 will make log(x+2) to result in a non-real number. This is due to the fact that the domain of log(x) is x > 0. So the domain of log(x+2) is x > -2.

If BCDE is congruent to OPQR, then DE is congruent to _______.
Answer:
QR
Step-by-step explanation:
If two shape are congruent, it means they have equal corresponding sides and angles. You can find which ones are corresponding to each other by where the letters are placed in the shapes given name.
For example, given: BCDE & OPQR
BC = OP
CD = PQ
DE = QR
Notice that DE is the 3rd and last letter in BCDE
QR is also the 3rd and last letter of OPQR
