Answer:
x = 2/9
Step-by-step explanation:
x + 1/9 = 1/3
Subtract 1/9 from each side
x + 1/9 -1/9 = 1/3 - 1/9
Get a common denominator
x = 1/3 *3/3 - 1/9
x = 3/9 -1/9
x = 2/9

Cierta clase de microbio se duplica en cada minuto. Si se coloca un microbio en un recipiente de una capacidad determinada, este se llena a los 30 min. ¿En que tiempo se llenará el recipiente si se colocan 2 microbios?
Answer:
En este problema se trata de una función exponencial, donde la cantidad de microbios en el recipiente se duplica cada minuto.
Si x representa el número de minutos transcurridos y y la cantidad de microbios en el recipiente, entonces se puede expresar la función exponencial como:
y = a * (2)^x
Donde "a" es la cantidad inicial de microbios en el recipiente, en este caso a = 1.
Después de 30 minutos, la cantidad de microbios en el recipiente es:
2^30 = 1,073,741,824
Esto significa que si se coloca un solo microbio en el recipiente, se tardará 30 minutos en llenarlo.
Si se colocan 2 microbios en el recipiente, entonces la cantidad inicial de la función exponencial es a = 2, y se busca el valor de x tal que:
2 * (2)^x = 1,073,741,824
Dividiendo ambos lados por 2, se tiene:
(2)^x = 536,870,912
Tomando logaritmos base 2 en ambos lados, se tiene:
x = log2(536,870,912) = 29
Por lo tanto, si se colocan 2 microbios en el recipiente, se tardará 29 minutos en llenarlo.

Given the equations of the circles:
\(\begin{gathered} x^2+y^2=4 \\ \\ x^2+y^2=1 \end{gathered}\)a. You can identify that they are written in this form:
\(x^2+y^2=r^2\)That is the form of the equation of radius "r" whose center is at the Origin.
In this case, you can identify that:
- For the first circle:
\(r^2=4\)Then, solving for "r", you get that its radius is:
\(r=\sqrt[]{4}=2\)- For the second circle:
\(r^2=1\)Therefore, its radius is:
\(r=\sqrt[]{1}=1\)Hence, knowing their centers at the Origin and knowing the radius, you can graph the circles on the same Coordinate Plane:
Notice that the larger circle is:
\(x^2+y^2=4\)And the small circle is:
\(x^2+y^2=1\)b. Now you have to find the image of any point on the larger circle under the following transformation:
\((x,y)\rightarrow(\frac{1}{2}x,\frac{1}{2}y)\)Choosing this point on the larger circle:
\((2,0)\)You need to multiply each coordinate by the following scale factor (based on the given rule), in order to find its image:
\(k=\frac{1}{2}\)Therefore, you get:
\((2,0)\rightarrow(2\cdot\frac{1}{2},0\cdot\frac{1}{2})=(1,0)\)You can plot both points on the Coordinate Plane:
c. By analyzing the graph and the points plotted, you can conclude that the small circle is obtained by dilating the larger circle, using the Origin as the Center of dilation and this scale factor:
\(k=\frac{1}{2}\)Since is smaller than the larger circle, it is a reduction of it.
Hence, the answers are:
a.
The larger circle is:
\(x^2+y^2=4\)The small circle is:
\(x^2+y^2=1\)b.
\((1,0)\)c. The small circle is a reduction of the larger one using the origin as the center and a scale factor of:

you can buy a deck, a set of 4 wheels, a set of 2 trucks and a set of
hardware, and assemble your own board. The prices for the shop's
products are:
Answer:
minimum: 80 zeds
maximum: 137 zeds
Step-by-step explanation:
minimum price is where you choose all the cheapest options
lowest deck price is 40, lowest wheel set price is 14...
40+14+16+10
=40+30+10
=80
maximum price is where you choose all the most expensive options
highest deck is 65, highest price of wheels are 36, hardware 20
65+36+16+20
=65+72

find the surface area
The surface area of the given sphere is 764.15 square inches.
Given that, the sphere has diameter = 15.6 inches.
Here, radius = 15.6/2 = 7.8 inches
We know that, surface area of a sphere is 4πr².
Now, surface area = 4×3.14×7.8²
= 764.15 square inches
Therefore, the surface area of the given sphere is 764.15 square inches.

Step-by-step explanation:
To determine the value of x that satisfies the expression x^2 + 3x - 5 when x = 9, we simply substitute 9 for x and evaluate the expression:
9^2 + 3(9) - 5 = 81 + 27 - 5 = 103
Therefore, when x = 9, the expression x^2 + 3x - 5 evaluates to 103.

4 Last year a football team scored at least one goal in 65% of their matches.
This year they played 40 matches and scored at least one goal in 28 of them.
Has their performance got better or worse?
Give a reason for your answer.
Answer:
Their performance got better, as they scored at least one goal in a higher percentage of matches.
Step-by-step explanation:
Last year:
The team scored at least one goal in 65% of their matches.
This year:
This year they played 40 matches and scored at least one goal in 28 of them. So
28*100%/40 = 0.7*100% = 70%
This year the team scored at least one goal in 70% of their matches, which is a higher percentage(5% higher) than last year.
Has their performance got better or worse?
Their performance got better, as they scored at least one goal in a higher percentage of matches.
1 The figure shows a rectangle inscribed in a circle.
Determine the area of the shaded region. Use 3.14
for and round to the nearest tenth.
Answer:
46.8 cm²
Step-by-step explanation:
The diagonal of the square has length \(\sqrt{6^2+10^2}=2\sqrt{34}\). Therefore, the radius of the circle is \(\sqrt{34}\), meaning the area is \(\pi(\sqrt{34})^2 \approx 34(3.14)=106.76\).
The area of the rectangle is \((6)(10)=60\) cm².
Subtracting the areas, the answer is 46.76 cm², which is 46.8 cm² to the nearest tenth.
The lion population in a certain reserve drops by 5% every year. Currently, the population's size is 325. i.Write a function that gives the lion population size,P(t), t years from today ii. What will the population be in 4 years. Write an exponential function for all three
Answer:
1. The function that gives the lion population size P(t), t years from today is:
P(t) = 325(0.95)^t
2. To find the population in 4 years, we can substitute t=4 in the function:
P(4) = 325(0.95)^4
P(4) = 279.14
So the population will be approximately 279 lions in 4 years.
3. The exponential function for all three years is the same as in part 1:
P(t) = 325(0.95)^t

Find the Measure of an interior angle of regular hexagon (6 sides polygon).X=Hunt sum=(n-2)180
it is known that formula for the sum of the interior angles of a polygon is
sum = (n - 2) 180 (given )
here n is the number of side of a polygon
here we have 6 sides in a regular hexagon
so put n = 6
sum = (6 - 2) x 180
sum = 4 x 180 = 720 degrees.
the sum of all 6 interior angles is 720 degrees,
as all the interior angles are equal in a regular hexagon
so the measure of interior angle (x) is
x = 720/6
x = 120 degrees
so each interior angle is 120 degrees.

a. (1/3)x² - (2/5)xy + 2y² + (2/15)xy - 3x² + (3/4)y²
To simplify this, add or subtract like terms. That is:
(1/3)x² - (2/5)xy + 2y² + (2/15)xy - 3x² + (3/4)y²
= (1/3)x² - 3x² - (2/5)xy + (2/15)xy + 2y² + (3/4)y²
