The last expression is equivalent to √5³.
What equation contains an expression?
The equal to sign (=) is the best indicator of whether a given problem is an equation or an expression because it indicates that the problem is an equation.
It is only an expression if there isn't an equal to (=) sign present. It contains data that is used to demonstrate value, such as numbers, variables, and operators.
[tex]= ( 5^{1/8} * 5^{3/8} )[/tex]
[tex]= ( 5^{1/8} * 5^{3/8} ) \\= 5^{(1/8 + 3/8)}[/tex]
[tex]= 5^{4/8}[/tex]
[tex]= 5^{(1/2)}[/tex]
[tex]= [5^{(1/2)}]^{3}[/tex]
Because of the "Power of a power property"
= [tex]5^{3/2}[/tex]
The last expression is equivalent to √5³.

so 10+3 is equal to 13
a number y times fives is at most one hundred
Answer:
20
Step-by-step explanation:
twenty times five is one hundred, so, I hope that's the answer you're looking for
Answer:
y <= 20
Step-by-step explanation:
Since it says a number y, our variable is y.
The number is multiplied by 5 which gives us 5y.
It is at most one hundred which means this is an inequality. It is AT MOST which means that 100 is a possible value. This means that our inequality is:
5y <= 100
Now we divide both sides by 5 to isolate y
y <= 20

The area of a room is 425 square feet. The length is (x+9) feet and the width is (x+1) feet. Find the dimensions of the room.
Answer:
width is 17
length is 25
Step-by-step explanation:
(x+9)(x+1) =[tex]x^{2}[/tex] + 10x + 9 = 425
[tex]x^{2}[/tex] + 10x - 416 = 0
(x-16)(x + 26) = 0
x = 16 or x = -26
x cannot be -26
x = 16
so, (16 + 1) = 17
(16 + 9) = 25
On a game show, a contestant randomly chooses an envelope and wins
the prize that is written inside. There are 3 envelopes containing a car,
5 envelopes containing a vacation, and 2 envelopes containing
electronics.
What is the probability that a contestant picks a vacation?
Answer:
D or 1/2
Step-by-step explanation:
If there are 3 envelopes for a car, 5 envelopes for vacation, and 2 envelopes for an electronic, then add 3+5+2=10. But, we are figuring out the vacation envelopes, which there are 5 of those and 5 is half of 10. Therefore, your answer is 1/2.

Where the graphs of the functions intersect it represents the number of weeks when they have both saved the same amount of money. So by solving the system we can find the number of weeks and that amount of money.
y = x^2 + 2x
y = -3x + 6 so
x^2 + 2x = -3x + 6
x^2 + 5x - 6 = 0
(x + 6)(x - 1) = 0
So x = 1 ( we ignore the negative)
So after 1 week they have saved the same amount and the amount is -3 + 6 = 3.
Are you sure that -3x + 6 is right - because Sarah does not save anything after year 1 . The equation has a negative slope!!
Answer:
x=5
Step-by-step explanation:
35+4x=x^2+30
collect the like terms n form a quadratic equation
x^2-4x-5=0
solve the quadratic equation
x=5 or x=-1
ignore the negative answer bcz week cant be negative
So the answer is 5 weeks

Ayudemen porfavor . Determine 4 ala potencia x + 4 ala potencia -x, si se sabe que 2ala potencia x + 2 ala potencia -x =3
Answer:
Es igual a 7.
Step-by-step explanation:
Ok, sabemos que:
[tex]2^x + 2^{-x} = 3[/tex]
Queremos calcular:
[tex]4^x + 4^{-x}[/tex]
Tambien sabemos que 4 = 2*2
Entonces:
[tex]4^x + 4^{-x} = (2*2)^x + (2*2)^{-x}[/tex]
y sabemos que 2*2 = 2^2
Entonces:
[tex]4^x + 4^{-x} = (2*2)^x + (2*2)^{-x} = (2^2)^x + (2^2)^{-x}[/tex]
y ahora podemos usar la relación:
[tex](a^n)^m = (a^m)^n = a^{m*n}[/tex]
entonces:
[tex](2^2)^x + (2^2)^{-x} = (2^x)^2 + (2^{-x})^2[/tex]
Ahora podemos completar cuadrados sumando y restando el termino:
[tex]2*(2^x)*(2^{-x})[/tex]
Asi tendremos:
[tex](2^x)^2 + (2^{-x})^2 = (2^x)^2 + (2^{-x})^2 + 2*(2^x)*(2^{-x}) - 2*(2^x)*(2^{-x}) = (2^x + 2^{-x})^2 - 2*(2^x)*(2^{-x})[/tex]
Entonces de momento tenemos que:
[tex]4^x + 4^{-x} = (2^x + 2^{-x})^2 - 2*(2^x)*(2^{-x})[/tex]
Sabemos que el termino que esta dentro del parentesis es igual a 3.
Y tambien podemos usar la propiedad:
[tex]a^n*a^m = a^{n + m}[/tex]
en el termino de la derecha.
Asi tendremos:
[tex](2^x + 2^{-x})^2 - 2*(2^x)*(2^{-x}) = (3)^2 - 2*2^{x + (-x)} = 9 - 2 = 7[/tex]

What is the radius of these cylinders?
Answer:
sorryyyyy i really dont know
Find the volume of the cylinder. Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi radius 5 height 6
Answer:
150π cu. units
Step-by-step explanation:
V = Bh where B is the area of the circular base and h is the distance between the bases (height)
B = [tex]\pi r^{2}[/tex] = [tex]\pi 5^{2}[/tex] = 25π
V = 25π(6) = 150π cu. units
Answer: V = 471 m^3
In terms of PI - V = 150 π m^3
Step-by-step explanation:
V = πr2h
V = 3.14(5)^2(6)
V = 3.14(25)(6)
V = 471 M^3
or
V = 3.14 (25)(6)
V = 150 π m^3

Im practicing for a state test im taking- i am a 7th grader doing 9th grade algebra because well yeah im smort- anyways- my teacher and all of us thought the answer was 40% but it wasnt she gave us the answer of 62.5%- she wants us to explain how she got that answer can anyone help me.
Answer:
62.5%
Step-by-step explanation:
the question is worded weirdly but basically since they're saying "given that a state does not use nuclear power", you can ignore the ones that do use nuclear power.
20 + 12 = 32
and then u have to find the percentage that do use coal (20). to do that all you have to do is divide then move the decimal place backwards 2 times
20 ÷ 32 = 0.625
62.5%

There are 42 more red marbles in a jar than there are white marbles. If there are 238 marbles in the jar, how many of them are red and how many are white?
Answer: red marbles = 140
White marbles = 98
Step-by-step explanation:
Let the number of white marbles be represented by x
Since there are 42 more red marbles in a jar than there are white marbles, red marbles will be: = x + 42
Since there are 238 marbles in the jar, this can be represented in an equation as:
x + x+42 = 238
2x + 42 = 238
2x = 238 - 42
2x = 196
x = 196/2
x = 98
White marbles = 98
Red marbles = x + 42
= 98 + 42
= 140
