Step-by-step explanation:

Answer:

Elliot = 16 years old

Miya = 10 years old

Cara = 25 years old

Step-by-step explanation:

Define the variables:

The average age of Elliot, Miya and Cara is 4 years more than the average age of Elliot and Miya:

\(\implies \dfrac{x+y+z}{3}=\dfrac{x+y}{2}+4\)

\(\implies \dfrac{x+y+z}{3}=\dfrac{x+y+8}{2}\)

\(\implies 2(x+y+z)=3(x+y+8)\)

\(\implies 2x+2y+2z=3x+3y+24\)

\(\implies 2z=x+y+24\)

\(\implies x=2z-y-24\)

Cara is 9 years older than Elliot:

\(\implies z = x + 9\)

Four years ago, Elliot was double the age of Miya:

\(\implies (x - 4) = 2(y - 4)\)

\(\implies x - 4 = 2y-8\)

\(\implies x +4 = 2y\)

\(\implies y=\dfrac{1}{2}x +2\)

Substitute the equations for z and y into the equation for x and solve for x:

\(\implies x=2z-y-24\)

\(\implies x=2(x+9)-\left(\dfrac{1}{2}x +2\right)-24\)

\(\implies x=\dfrac{3}{2}x-8\)

\(\implies \dfrac{1}{2}x=8\)

\(\implies x=16\)

Substitute the found value of x into the equation for z and solve for z:

\(\implies z = 16 + 9\)

\(\implies z = 25\)

Substitute the found value of x into the equation for y and solve for y:

\(\implies y=\dfrac{1}{2}(16) +2\)

\(\implies y=8+2\)

\(\implies y=10\)

Therefore, the ages of Elliot, Miya and Cara are:

Step-by-step explanation:

With given percentages of taxes on income, Alex and Tory owe $18,882 in federal taxes.

what exactly is a percentage?

A percentage is a way of representing a number as a fraction of 100. It is often denoted by "%". For example, 50% means 50 out of 100, or 0.5 as a decimal. Percentages are commonly used to express rates, ratios, and proportions in many areas such as finance, statistics, and everyday life.

Now,

Since the couple is married and filing jointly, their standard deduction is $25,900. Thus, their taxable income is $150,000 - $25,900 = $124,100.

From the tax table, the tax on the first $19,750 is 10% and the tax on the next $60,500 ($80,250 - $19,750) is 12%. The remaining taxable income is $124,100 - $80,250 = $43,850, which falls into the 22% tax bracket.

Therefore, the tax owed on the first $19,750 is $1,975 (10% of $19,750), the tax owed on the next $60,500 is $7,260 ($1,975 plus 12% of $60,500 - $19,750), and the tax owed on the remaining $43,850 is $9,647 (22% of $43,850).

The total tax owed is the sum of these amounts: $1,975 + $7,260 + $9,647 = $18,882. Therefore, Alex and Tory owe $18,882 in federal taxes.

The measure of the angles 1,2 and 3 are 75, 42 and 138 respectively.

The value of ∠1 = 180- 105             [supplementary angles]

∠1 = 75°

∠1 + ∠2 + 63° = 180                          [angle - sum property]

75 + ∠2 + 63 = 180

∠2 = 180 - (75 + 63)

∠2 = 42°

∠2 + ∠3 = 180                                       [supplementary angles]

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.

Answer:

x < -3 or x > 2

Step-by-step explanation:

x² + x - 6 > 0

Convert the inequality to an equation.

x² + x - 6 = 0

Factor using the AC method and get:

(x - 2) (x + 3) = 0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

x - 2 = 0

x = 2

x + 3 = 0

x = -3

So, the solution is x < -3 or x > 2

The surface area of the sphere is 1810 cm²

A sphere is a three-dimensional object that is round in shape. Examples of object with spherical shape is a ball, an egg e.t.c.

The area occupied by a three-dimensional object by its outer surface is called the surface area.

The surface area of sphere is expressed as;

A = 4πr². where r is the radius.

A = 4 × 3.14 × 12²

A = 1809.7 cm²

According to the properties of the standard normal distribution, approximately 99.7% of the values lie within three standard deviations of the mean. Therefore, the answer is 99.7%.

To determine the percentage of videos on the streaming site that are between 264 and 489 seconds, we need to calculate the area under the normal curve within that range. Since the distribution is approximately normal with a mean of 264 seconds and a standard deviation of 75 seconds, we can use the properties of the standard normal distribution to find the desired percentage.

First, we need to convert the values 264 and 489 to z-scores, which represent the number of standard deviations a particular value is away from the mean. The z-score formula is given by:

z = (x - μ) / σ

where x is the value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get:

z1 = (264 - 264) / 75 = 0

z2 = (489 - 264) / 75 = 3

Next, we can use a standard normal distribution table or a calculator to find the area under the curve between z = 0 and z = 3. The area represents the percentage of videos falling within that range. The answer is 99.7% .

\(y=\frac{4}{5}x+4\)

Step-by-step explanation:

You'll need to get this equation in slope-intercept form by solving for y. I do a little extra here to get it in the correct form, but I think it's pretty clear. Let me know if I need to clarify.

\(\\\\\frac{8x}{5}-2y=-8\\\\-2y=-\frac{8x}{5}-8\\\\2y=\frac{8x}{5}+8\\\\y=\frac{4}{5}x+4\)

Dustin has more money than Stephanie by $100

To determine who has more money, we need to calculate the current savings balance for each person.

Let's start with Stephanie. If she earns $10.50 per hour, we can calculate her earnings by multiplying her hourly rate by the number of hours worked. She works 20 hours per week.

Her weekly earnings would be:

$10.50/hour x 20 hours = $210

Assuming she deposits all of her earnings into her savings account, her total savings balance after one week would be:

$200 (initial deposit) + $210 (one week's earnings) = $410

Now let's calculate Dustin's savings balance. He earns $8.00 per hour and works 20 hours per week, his weekly earnings would be:

$8.00/hour x 20 hours = $160

Assuming he also deposits all of his earnings into his savings account, his total savings balance after one week would be:

$350 (initial deposit) + $160 (one week's earnings) = $510

Therefore, Dustin has more money than Stephanie by $100 ($510 - $410).

The side lengths from least to greatest as follows:

IK < KL < IJ < IL < LJ

To order the side lengths IK, KL, IJ, IL, and LJ from least to greatest, we can analyze the given figure.

Since the figure is not drawn to scale, we cannot determine the exact lengths of the sides. However, we can make some observations based on the given angles.

Let's analyze the angles:

Angle L: Since angle L is marked as 47°, we know that side KL is the shortest side, as it is opposite to the smallest angle in a triangle.

Angle I: Since angle I is marked as 20°, we can infer that side IJ is longer than side IK, as it is opposite to a larger angle.

Angle LJ: Since angle LJ is marked as 89°, we can conclude that side LJ is the longest side, as it is opposite to the largest angle in the triangle.

Based on these observations, we can order the side lengths from least to greatest as follows:

IK < KL < IJ < IL < LJ

The average rate of change of function f(x) over the interval a ≤ x ≤ b is calculated as follows:

where f(b) and f(a) are the function f(x) evaluated at x = b and x = a respectively.

In this case, the function is:

And the interval is -1 ≤ x ≤ 7. Evaluating f(x) at x = 7 and x = -1:
