Answer:
2.) B. 14
3.) C. 36 x 10 (to the 6th power)
Step-by-step explanation:
In number 2, when it comes to exponents like that, you're supposed to multiply em, nd when u do that, u get 12. It said find the sum, so u add 12 nd 2 nd get 14.
In number 3, u basically gotta find the area nd that's jus multiplyin 6 x 10 (to the 3rd power) by itself, nd that's the answer u get.
Also, since I really tried, I would really appreciate it if u marked me as brainliest.
Si un hombre de 1.75m de altura proyecta una sombra de 3.50m que sombra aproximada proyecta un poste de 8.25m
Answer:
4.25 m
Step-by-step explanation:
Resolvemos esta pregunta usando la fórmula:
Altura del hombre / Sombra de un hombre = Altura del palo / Sombra del palo
Sombra del hombre = 3.50 m
Altura de un hombre = 1.75 m
Sombra del palo = 8.50 m
Altura del palo = x
Por lo tanto:
1.75 / 3.5 = x / 8.5
Cruz multiplicar
1.75 × 8.5 = 3.5 × x
14.875 = 3.5x
x = 14.875 / 3.5
x = 4.25 metros
Por tanto, la altura del palo = 4.25 m
4. Which property of operations is used to write 15x + 9 as 9 + 15x?
Solution: The commutative property of addition states that when two numbers are being added, their order can be changed without affecting the sum.
Simplify the expression: 9-2X + 8 + x + 5x
Answer:
4x + 17
Step-by-step explanation:
9 - 2x + 8+ x + 5x
Add/Subtract the values with variables together and the same case for the values without any variables.
5x + x - 2x = 4x
9 + 8 = 17
So you'll end up with the following,
4x + 17

The speed of light is about 300,000,000 meters per second. That's
about 3 * 10^8 meters per second. The speed of sound in dry air is
about 3 * 10^2 meters per second.
About how many times faster does light travel than sound in dry air?
Answer:
Light is about 299,999,700 mps (meters per second) faster than sound in dry air.
Step-by-step explanation:
We know that the speed of light is about 3 × 10 ^ 8 meters per second and that the speed of sound in dry air is about 3 × 10 ^ 2 meters per second. We need to solve 3 × 10 ^ 8 minus 3 × 10 ^ 2.
3 × 10 ^ 8 - 3 × 10 ^ 2 =
300,000,000 - 300 = 299,999,700
Light is about 299,999,700 mps (meters per second) faster than sound in dry air.

Answer:
a = 8, b = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given the exponential function
f(x) = a[tex]b^{x}[/tex]
To find a and b use the given coordinate points on the graph
Using (0, 8 ), then
8 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then
a = 8
f(x) = 8[tex]b^{x}[/tex]
Using (2, 18 ) , then
18 = 8b² ( divide both sides by 8 )
[tex]\frac{18}{8}[/tex] = b² , that is
b² = [tex]\frac{9}{4}[/tex] ( take the square root of both sides )
b = [tex]\sqrt{\frac{9}{4} }[/tex] = [tex]\frac{3}{2}[/tex]
Thus
f(x) = 8[tex](\frac{3}{2}) ^{x}[/tex]

My computer wont allow it but the 5 and the 7 are exponents
Answer:
[tex]-108x^{5}y^{7}[/tex]
Step-by-step explanation:
Simplify using the laws of exponents (there are more rules than listed, these given rules are just the ones that come into play here);
- when there is a term in parenthesis with an exponent outside, the term's exponent gets multiplied by the exponent outside
- when multiplying two exponents, one can only combine terms with the same base, and one must add the exponents
[tex](3xy^{2})^{3}*(-4x^{3}y)\\\\=(3^{3}*x^{3}*y^{2{^{3}}}) *(-4x^{2}y)\\\\=(27x^{3}y^{6})(-4x^{2}y)\\\\=-108x^{5}y^{7}[/tex]

ILL MARK YOU BRAINLIEST To join a health club, a person must pay a $75 one-time fee plus a charge of $30 per month. This situation can be presented by an equation of the form y=mx+b, where x = the fire in months and ythe
total cost in dollars. What is the value of b in this equation?
Answer: b=75
Step-by-step explanation: Given that the health club charges $30 per month, we know that this is the "m" varible. We know this because the total value changes as the value of x changes. The value of b would therefore be $75 dollars because it is a constant and a one time fee. The person joining the health club pays an amount of money per month, as well as an initial charge of $75.

A sports drink bottle contains 16.9 fluid Ounces. Andre drank 80% of the
bottle. How many fluid Ounces did Andre drink?
Answer:
13.52 fluid ounces should be the right answer! :)
Step-by-step explanation:
Andre drank from the bottle 13.52 fluid ounces if he drank 80% of bottle.
What is Percentage?Percentage is defined as the parts of a number in a whole of 100. This is denoted by the symbol '%'.
In other words, percentage can be defined as the ratio expressed as a fraction of 100.
Any number can be expressed as a percentage of another number by dividing the number with the whole of other number and then multiplying with 100.
Given that, fluid contained in a sports bottle = 16.9 fluid ounces.
Andre drank 80% of the fluid contained in the bottle.
80% of the bottle = 80% × 16.9
= (80 / 100) × 16.9
= 0.8 × 16.9
= 13.52
So this is the total fluid ounces Andre drink.
Hence Andre drank 13.52 fluid ounces from the bottle.

solve: 2x+3y=1
y=-2x+11
Answer:
(8, -5); x=8; y=-5
Step-by-step explanation:
i'll be solving via substitution
2x+3y=1; y=-2x+11
2x + 3(-2x +11) = 1
2x -6x +33 = 1
-4x = -32
x = 8
2(8) + 3y = 1
16 + 3y = 1
3y = -15
y = -5
(8, -5)
Check:
-5 = -2(8) + 11
-5 = -16 + 11
-5 = -5
The graph of a proportional relationship contains the point (8,4). What is the corresponding equation? Enter your answer as a fraction in simplest form by filling in the boxes.
y= — x
Given:
The graph of a proportional relationship contains the point (8,4).
To find:
The corresponding equation.
Solution:
If y in directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
Where, k is the constant of proportionality.
The graph of a proportional relationship contains the point (8,4).
Putting x=8 and y=4 in (i), we get
[tex]4=k(8)[/tex]
[tex]\dfrac{4}{8}=k[/tex]
[tex]\dfrac{1}{2}=k[/tex]
Putting [tex]k=\dfrac{1}{2}[/tex] in (i), we get
[tex]y=\dfrac{1}{2}x[/tex]
Therefore, the required equation is [tex]y=\dfrac{1}{2}x[/tex].
