Answer: The answer is 9
Step-by-step explanation:
It is 9 because 3x3x3x3 is basically 9x9 and 9x9 is 81, so 81 is the numerator. Then we gat to the denominator, which is 3x3 and 3x3 is 9. So the new fraction you get is 81/9, which is basically 81 divided by 9. 81 divided by 9 is 9.
Answer:
9
Step-by-step explanation:
Subtract 2 from the 4 exponents on the numeral, then multiply that exponent, which would be 3×3=9 .
Sam is transferring files from his friend's laptop into his flash drive. This is the formula for the size of the files on Sam's friends drive S (measured in megabytes) as a function of time t (measured in seconds): S(t)=5t+45
Use the above information to answer the following:
When the transfer began the drive had___ megabytes of files on it
Every 10 seconds, an additional___ megabytes are transferred into the drive.
Answer:
1. 45 megabytes
2. 50 megabytes
Step-by-step explanation:
Given
S(t) = 5t + 45
Required
Find S(t) when the transfer began
And find the additional transfer size at interval of 10 seconds
When the file transfer initially began, the value of t is 0.
Given that S(t)=5t+45.
Substitute 0 for t
S(0)=5 * 0 + 45
S(0) = 0 + 45
S(0) = 45.
Hence, the hard drive had 45 megabytes on it when the transfer started.
At every interval of 10 seconds. We take t to be 10, 20, 30...seconds
When t = 10
S(t)=5t+45 becomes
S(10) = 5(10) + 45
S(10) = 50 + 45
S(10) = 95 megabytes
When t = 20
S(t)=5t+45 becomes
S(20) = 5(20) + 45
S(20) = 100 + 45
S(20) = 145 megabytes
When t = 30
S(t)=5t+45 becomes
S(30) = 5(30) + 45
S(30) = 150 + 45
S(30) = 195 megabytes
Calculating the difference
Difference = S(30) - S(20) or S(20) - S(10)
Difference = 195 - 145 or 145 - 95
Difference = 50 or 50
See that the difference is the same.
So, at every 10 seconds interval, there's an additional 50 megabytes transferred

How to solve for x 2x + 3x -5 =20
Answer: x=5
Step-by-step explanation:
Simplify to 2x+ 3x -5 to 5x-5
5x- 5 = 20
Add 5 to both sides.
5x= 20+5
Simplify 20+5 to 25.
5x= 25
Divide both sides by 5.
x= 25/5
Simplify 25/5 to 5.
x=5
Which describes the law of conservation of matter?
A. The total number of atoms cannot change during a reaction.
B. Chemical reactions cannot change reactants into products.
C. The reactants must have more atoms than the products.
D. A reaction has the same type of molecules before and after.
Answer: Choice A) the total number of atoms cannot change during a reaction
Matter cannot be created or destroyed. Instead, matter can be rearranged from one form to another. For example, boiling water turns the liquid into gas (steam) when it evaporates. The H2O molecules haven't been created or destroyed.

coin is 0.33 cm smaller. What is the first step to find the diameter of the smaller coin? What is the
22
diameter of the smaller coin? Use for .
7
What is the first step to find the diameter of the smaller coin?
Answer:
First step will be option D.
Diameter of the smaller coin will be 2.45 cm
Step-by-step explanation:
Circumference of one coin = 8.03 cm
Circumference of the smaller coin = Circumference of the larger coin - 0.33
= 8.03 - 0.33
= 7.7 cm
Circumference of the smaller coin = 2πr = 7.7
r = [tex]\frac{7.7}{2\pi }[/tex]
r = [tex]\frac{7.7\times 7}{2\times 22}[/tex]
r = 1.225 cm
Diameter of the smaller coin = 2 × radius of the smaller coin
= 2 × 1.225
= 2.45 cm
Therefore, first step will be option D.
Diameter of the smaller coin will be 2.45 cm
the height of a kicked soccer ball is represented by the function f(x)=8x-2x^2 where x is the number of seconds since the ball was iicked and f(x) is the height of the ball. when will the soccer ball hit the ground?
Answer:
Result at time x = 4 seconds the soccer ball hit the ground.
Step-by-step explanation:
At the moment just before the ball is kicked, it is on the ground and so the height f(x) is zero meters. After the kick, the ball goes through the air and it's path can be described by a (mountain) parabola.
So lets see after how many second (x) the height = 0 once again.
f(x) = 8x-2x^2
f(x) = 0
8x - 2x^2 = 0
Try to write the formula in two terms
-2x * (x - 4) = 0
When a product of two or more terms equals zero, then at least one of the terms must be zero.
Now solve each term = 0 separately, meaning, solve as many equations as there are terms in the product.
Any solution of term = 0 solves product = 0.
Solve the first term:
-2x = 0
Multiply left an right from the = singn with the factor -1 gives this outcome:
2x = 0
x = 0
Solve the second term:
x-4 = 0
x = 4
Result at time x = 4 seconds the soccer ball hit the ground.
x = 4
x = 0

Which inequality is true for x = 2?
A) 6x + 20 < 29
B) 7x − 10 < 11
C) 14x + 10 < 37
D) 15x − 18 < 12
Answer: d.
Step-by-step explanation:
Add 18 to both sides.
15x<12+18
Simplify 12+18 to 30.
15x <30
Divide both sides by 15.
x < 15/30
Simplify 30/15 to 2.
x < 2
The inequality 15x − 18 < 12 is true for x = 2
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.

C. A = 68.6° C = 45.40; b=12.0
b. A = 71.6°; C = 45.40; b =15.0
d. A = 68.6°; C = 52.89; b=15.0
Answer:
b. A = 71.6°; C = 45.40°; b =15.0
Step-by-step explanation:
The missing values can be found with the help of the Law of Cosine and properties of triangles:
Side b (Law of Cosine)
[tex]b = \sqrt{a^{2}+c^{2}-2\cdot a \cdot c \cdot \cos B}[/tex]
[tex]b = \sqrt{16^{2}+12^{2}-2\cdot (16)\cdot (12) \cdot \cos 63^{\circ}}[/tex]
[tex]b \approx 15.022[/tex]
Angle A (Law of Cosine)
[tex]\cos A = -\frac{a^{2} - b^{2}-c^{2}}{2\cdot b \cdot c}[/tex]
[tex]\cos A = - \frac{16^{2}-15.022^{2}-12^{2}}{2\cdot (15.022)\cdot (12)}[/tex]
[tex]\cos A = 0.315[/tex]
[tex]A= \cos^{-1} 0.315[/tex]
[tex]A \approx 71.639^{\circ}[/tex]
Angle C (Sum of internal angles in triangles)
[tex]C = 180^{\circ} - 63^{\circ} - 71.639^{\circ}[/tex]
[tex]C = 45.361^{\circ}[/tex]
Hence, the right answer is B.
