Which expression represents (−21−−−−√5)6 in rational exponent form? (−21)6/5 −215/6 (65)−21 (56)−21
Answer:
[tex](-21)^\frac{6}{5}[/tex]
Step-by-step explanation:
Which expression represents [⁵√(−21)]⁶ in rational exponent form?
Solution:
Rational numbers are numbers which can be expressed as fractions in the form a / b, where a, b are integers and b is not equal to zero.
A rational exponent is an exponent that is a fraction. For example √2 = [tex]2^\frac{1}{2}[/tex].
When expressing a number in rational exponent form, the numerator of the fractional exponent refers to a normal power, but the denominator refers to the root.
[tex][\sqrt[5]{(-21)}]^6 = (-21)^\frac{6}{5}[/tex]
Simplify (5r^2t)^2(3r^0t^4)
-4 1/2 + (-2 1/3)
[tex]-4 \frac{1}{2} + (-2 \frac{1}{3} )[/tex]
[tex]-4\frac12+(-2\frac13)=-4\frac12-2\frac13=-4\frac36-2\frac26=-(4\frac36+2\frac26)=-6\frac56\\\\\\5\frac25-6\frac57=5\frac{2\cdot7}{5\cdot7}-6\frac{5\cdot5}{7\cdot5}=5\frac{14}{35}-6\frac{25}{35}=-(6\frac{25}{35}-5\frac{14}{35})=-1\frac{11}{35}[/tex]

Jada walks up to a tank of water that can hold up to 15 gallons. When it is active, a drain empties from the tank at a constant rate. When Jada first sees the tank, it contains 12 gallons of water. Three minutes later, the tank contains 6 gallons of water.
At what rate is the amount of water in the tank changing. Use a signed number. (positive or negative number)
gallons per minute
How many more minutes will it take for the tank to drain completely?
minutes
How many minutes before Jada arrived was the water tank completely full?
minutes
Answer:
3 minutes 6 gallons of water is gone so therefor it would take 6 complete minutes but 3 more minutes

The radius of a circle is 9 times the radius of a smaller circle. The area of the smaller circle is 50 square centimeters. What is the area of the larger circle?
Answer:
Let R = radius of big circle
r=radius of small circle
A1=Area of small circle
A2=Area of big circle
R=9r
A1=50cm^2
A1=pi*r*2
A2=pi*R^2
A2=pi*(9r)^2
A2=81*pi*r^2
A2=81*A1
A2=4050cm^2
Hence the big circle has area of 4050cm^2
Step-by-step explanation:
The answer is 4050 cm²
What is the area and circumference of a circle?The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.
Given here: The radius of a circle is 9 times the radius of a smaller circle. And area of the smaller circle is 50 cm² then let the area of the larger circle be x
π9²/π1² =x/50
x=4050
Hence, The answer is 4050 cm²

Answer: 262.6
Step-by-step explanation: Well if she sold 110 hamburgers on tuesday for $545 That is a simple division equation (545/110). After dividing the answer would be how much each hamburguer cost on its own ( 4.954545454545455), you would then multiply that by the number of hamburgers she sold (53) and get your answer. (262.5909090909091) I am not quite sure where she wants us to round the answer to. so I just did the tens place.

Moes sells 10 tacos for $8.49 or Taco Bell sells 6 of the same kind of taco for $5.40. Which is a better deal? Clearly show the math that supports your answer. (labels are always helpful)
Answer:
The one that sells 10 tacos for $8.49
To get the better deal, you should find the selling prices for a single tacos in both cases and compare the amounts.
In the first one, 10 tacos for $8.49
This means 1 tacos sells for $8.49/10 = $0.849
In the second one, 6 for $5.40, this means for a single tacos, the selling price is $5.40/6 =$0.9
The better deal is the first one that sells one taco for $0.849 compared to the second one that sells one tacos for $0.9

Una recta atraviesa el punto (4,-6) Y tiene una pendiente igual a 5/4
Ayúdenme con este problemaaa porfavor
Answer:
y=5/4x-11
Step-by-step explanation:
tenemos un punto (4,-6) y una pendiente equal a 5/4.
usa la ecuación y=mx+b (m es la pendiente, b es el y interceptar)
porque sabemos la pendiente es 5/4, ahora mismo la ecuación es:
y=5/4x+b
en el punto, x=4, y=-6
podemos sustituir los números en la fómula para resolver b
-6=4(5/4)+b
-6=5+b
-11=b
entonces,
la ecuación de la recta es y=5/4x-11
