A general absolute value function can be rewritten into two equations, in this case these are:

x - 2 = 4 + x

x - 2 = -(4 + x)

The first one has no solution, but the second one does.

x - 2 = -(4 + x)

x - 2 = -4 -x

How much of​ a(n) 60% orange juice drink must be mixed with 5 gallons of a 30% orange juice drink to obtain a mixture that is 50% orange​ juice?

Answers

Answer: To obtain a mixture that is 50% orange juice, you must find the amount of 60% orange juice needed to bring the overall concentration of orange juice to 50%.

We can start by using the formula:

(amount of 60% orange juice) / (amount of 60% orange juice + amount of 30% orange juice) = desired concentration

Let's call the amount of 60% orange juice that we need to add x.

So the equation will look like this:

(x) / (x + 5 gallons) = 0.5

We can then solve for x:

x = (0.5 * x + 0.5 * 5 gallons)

x = 2.5 gallons

So, 2.5 gallons of 60% orange juice must be mixed with 5 gallons of 30% orange juice to obtain a mixture that is 50% orange juice.

Answers

Leia's ending balance after 5 years will be $3245.41. The solution has been obtained by using the concept of compound interest.

What is compound interest?

Both the principal and the interest that has accumulated over the previous period are used to compute interest. Compound interest accounts for the principal when calculating the interest for the subsequent month, in contrast to simple interest, which does not. In mathematics, compound interest is frequently denoted by the letter C.I.

We know that formula for compound interest is

[tex]A= P(1 + \frac{r}{n} )^{nt}[/tex]

So, here P = $2658 , n=12, t=5 and r = 0.04

Thus, we get

[tex]A= 2658(1 + \frac{0.04}{12} )^{60}[/tex]

[tex]A= 2658(1.00333})^{60}[/tex]

A = 2658*1.2207

A = $3245.41

Hence, Leia's ending balance after 5 years will be $3245.41.

For geometric shape no.4,∠1=26°,∠2=154°,∠3=26°,∠4=26°,

What are geometric shapes?

In Mathematics, Geometric shapes are the figures which demonstrate the shape of the objects we see in our everyday life. In geometry, shapes are the forms of objects which have boundary lines, angles and surfaces. There are different types of 2d shapes and 3d shapes.

Shapes are also classified with respect to their regularity or uniformity. A regular shape is usually symmetrical such as a square, circle, etc. Irregular shapes are asymmetrical. They are also called freeform shapes or organic shapes. For example, the shape of a tree is irregular or organic.

In plane geometry, the two-dimensional shapes are flat shapes and closed figures such as circles, squares, rectangles, rhombus, etc.  In solid geometry, the three-dimensional shapes are cube, cuboid, cone, sphere and cylinder. We can observe all these shapes in our daily existence also. For example books (cuboid shape), glasses (cylindrical shape), traffic cones (conical shape) and so on.

Now,

∠1+154°=180° -->∠1=26°   (supplementary angles)

∠1=∠3  (opposite angles) -->∠3=26°

∠2+∠3=180°

∠2=154°

∠1=∠7 --->∠7=26°

∠7+∠6=180° (supplementary angles)

∠6=154°

∠5+∠7=180° (supplementary angles)

∠5=154°

∠4+∠5=180° (supplementary angles)

∠4=26°

Talia travelled part of the journey by train and the rest by bus.The total fare was sh 400.On return,the fare of the bus was hiked by a half of what he paid and the total fare of the return journey hiked to sh 4800.Find the train fare.

Answers

Answer: Let x be the fare of the train, and y be the fare of the bus.

We know that:

x + y = 400 (the total fare of the journey)

And, on the return journey the fare of the bus is hiked by a half of what Talia paid initially, so the fare of the bus on the return journey is:

y * 1.5 = y + (y/2)

And the total fare of the return journey is hiked to 4800, so:

x + y + (y/2) = 4800

We can substitute the first equation into the second equation:

x + (y + (y/2)) = 4800

x + y + (y/2) = 4800

x + (y + (y/2)) = 4800

So, we can solve the system of equations by substituting the first equation into the second equation and solving for x.

x + y = 400

x = 4800 - (y + (y/2))

x = 4800 - y - (y/2)

x = 4800 - y - (1/2)y

x = (4800 - y) - (1/2)y

x = 4800 - (3/2)y

Now we have an equation for x in terms of y. To solve for x, we can use the value of y from the first equation

x = 4800 - (3/2)(400)

x = 4800 - 600

x = 4200

So the train fare is 4200 sh

Answers

Eva will earn $10.50 interest.

What is compound interest rate?

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

x = P(1 + r/n[tex])^{nt}[/tex]

,where x = compound interest

P = principal (the initial deposit or loan amount)

r = annual interest rate

n = the number of compounding periods per unit of time

t = the number of time units the money is invested or borrowed for

Given:

Eva deposited $50 in an account earning 10% interest compounded annually.

First, convert R as a percent to r as a decimal

r = R/100

r = 10/100

r = 0.1 rate per year,

Then solve the equation for A

A = P(1 + r/n[tex])^{nt}[/tex]

A = 50.00(1 + 0.1/1[tex])^{2}[/tex]

A = $60.50

Therefore, she will earn $10.50 of interest.

As per the 95% confidence interval, the true proportion of the professor's students who were registered to vote is between 57.3% and 82.7%

The term called confidence interval is defied as  the mean of your estimate plus and minus the variation in that estimate.

Here we know that  sample of 50 of her students randomly sampled from her 700 students, 35 said they were registered to vote.

Here we have to calculate the true proportion of the professor's students who were registered to vote with 95% confidence interval is,

Here we have a random sample of less than 10% of the professor's students with 35 expected successes and 15 expected failures

Here we have know that both of which are at least ten, so a Normal model applies.

Then the value of n = 50,

=> P =35/50 = 0.70

Then the value of q = 1 - p = 1 - 0.70 = 0.30

Then the value of SE is

=> √(0.70 0.30)/ 50 = 0.065

Then with 95% confidence interval is calculated as,

=>  p± SE(p)

Apply the values on it, then we get

Answers

The sheet metal should have a total area of 12.9 x 12.9 = 166.41 square feet.

The sheet metal must be large enough to form a cube with a volume of 300 cubic feet, so the side length of the sheet must be the cube root of 300, which is approximately 6.9 feet. To find the dimensions of the sheet metal, we must take into account the four 3 foot squares that will be removed from each corner. Therefore, the sheet metal should have a length of 6.9 feet + 6 feet (4 times the 3 foot squares) = 12.9 feet and a width of 12.9 feet. This will give the box a volume of 300 cubic feet, and the sheet metal should have a total area of 12.9 x 12.9 = 166.41 square feet.

High School B: B(t) = 550 + 85t

To find the interval of years in which High School A will have more students than High School B, we need to find the years in which A(t) > B(t).

So, we need to solve the inequality A(t) > B(t)

800 + 35t > 550 + 85t

250 > 50t
