Answer: 180
Step-by-step explanation:
Given
The population of 45 foxes doubles in 10 year period
Population follows [tex]y=45\cdot 2^x[/tex]
After 20 years i.e. x=2 Population is given by
[tex]y=45\cdot 2^2=45\times 4\\y=180[/tex]
Thus, there will be 180 foxes after 20 years
which property of equality should you use to solve the equation for x? -3x = 21
A. The division property of equality
B. The subtraction property of equality
C. The addition property of equality
D. The multiplication property of equality
Answer:
A. The division property of equality
Step-by-step explanation:
To get x you need to find a way to get it by itself, which can be done by dividing -3 from both sides of the equation (which is the division property of equality).
For example,
-3x=21
/-3 /-3
x=21/-3
x=-7
what is the volume ( round to nearest tenth if necessary)
Answer:
V = 240 cm^3
Step-by-step explanation:
The volume formula for a cone or triangular prism such as this one is
V = (1/3)(base area)(height), which here is:
V = (1/3)(80 cm^2)(9 cm), or V = 240 cm^3

Answer:
z=25
Step-by-step explanation:
(3+5)^2+[8-11]+z=4(z-2)
(8)^2 +3+z=4z-8
square 8
add 8 to both sides
mines z from both sides

Which statement about the quadratic equation below is true?
2x2 - 15x + 18 = 0
Answer:
x=3/2 or x=6
Step-by-step explanation:
2x2−15x+18=0
Step 1: Factor left side of equation.
2x^2-12x-3x+18=0
taking common factors
2x(x-6)-3(x-6)=0
(2x−3)(x−6)=0
Step 2: Set factors equal to 0.
2x−3=0 or x−6=0
x=3/2 or x=6

Answer:
A. 1 unit
Step-by-step explanation:
A cube has the same dimensions on each side, and the unit is 1 unit cube, none of the other options match.
You can easily rule out, B & D. That leaves you with A & C, and A makes the most sense, since 1 cubic unit would be the volume, and this question is only asking for the side length.
Good luck, hopefully, this helped!

The distance between second and third bases on a regulation baseball field is 90 feet. Scott says he needs to multiply to find the number of yards between the second and third bases. Do you agree? Support your answer
Answer:
Yes, distance in yards can be obtained by multiplication.
Step-by-step explanation:
Given that the distance between tow points is 90 feets, The distance between these two points in yards can be obtained either by multiplication or division.
I foot = 0.3333 yards
To convert distance between the second and third bases from feet to yard ;
Multiply distance in feets by 0.3333 to obtain the corresponding distance in yards ;
90 * 0.3333 = 29.997 = 30 yards

Vincent has a box of popsicles. There are 12 cherry, grape 10 orange, and 6 blue raspberry If he reaches in the box and pulls one out at random, what the probability it will be blue raspberry?
Answer:
6:28 or 3:14
Step-by-step explanation:
if you add all the flavor amounts up, which is 12 + 10 + 6, you get 28. 6 of those 28 popsicles are blue raspberry, so the ratio is 6:28. if it needs to be simplified, its 3:14 because 6/2 is 3 and 28/2 is 14
Answer:
6:28 if you add all Popsicles it gives you 28,so the probability that he will pick raspberry are 6 ,so if you simplyfy further its 3:14
Evaluate: 19 - 3k] = 3
Answer:
k = [tex]5\frac{1}{3} ,7\frac{1}{3}[/tex]
Step-by-step explanation:
|19 - 3k| = 3
-3k = 3 - 19
-3k = -16
k = 16/3
k = 5 1/3
-19 + 3k = 3
3k = 3 + 19
3k = 22
k = 22/3
k = 7 1/3

un refresco tiene una concentración de 3.8 x 10-4 de iones H+. determina el valor de PH de ese refresco
Answer:
El pH del refresco es 3.42.
Step-by-step explanation:
Se puede calcular el pH del refresco usando la siguiente fórmula:
[tex]pH = -log([H^{+}])[/tex]
En donde:
[H⁺]: es la cocentración de los iones H⁺ de la solución
Entonces, el pH es:
[tex]pH = -log([H^{+}]) = -log(3.8\cdot 10^{-4}) = 3.42[/tex]
El resutlado obtenido nos permite concluir que ese refresco es ácido.
Por lo tanto, el pH del refresco es 3.42.
Espero que te sea de utilidad!
Usando su fórmula, se encuentra que el valor de PH de ese refresco es dado por 3.42.
Cual es la fórmula para el valor de PH?Es dada por:
[tex]pH = -\log{H^{+}}[/tex]
Onde [tex]H^+[/tex] es la concentración.
En este problema, hay que la concentración es de [tex]H^+ = 3.8 \times 10^{-4}[/tex], por eso:
[tex]pH = -\log{H^{+}}[/tex]
[tex]pH = -\log{3.8 \times 10^{-4}}[/tex]
[tex]pH = 3.42[/tex]
El valor de PH de ese refresco es dado por 3.42.

Which of these can not form a perpendicular bisector?
O A. a line segment
O B. a circle
O C. a pair of parallel lines
O D. a right triangle
The solution is : Second option is correct. O B. a circle, can not form a perpendicular bisector.
What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.
here, we have,
Since we know that to form perpendicular bisector .
We need atleast two lines which form right angle.
So, right triangle can form perpendicular bisector with base and height.
Parallel lines can also form perpendicular bisector if a line is drawn from mid point of one line to mid point of another line.
A line segment can form perpendicular bisector.
But circle can't as it is curved shape it needs line to make perpendicular bisector.
Hence, Second option is correct. O B. a circle, can not form a perpendicular bisector.
