Answer: The number of pounds of sugar in 50% of syrup is 2.5 pounds.

Step-by-step explanation:

What is the percentage?

The percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Anton wants to make 5 pounds of sugar syrup.

Let x be the number of pounds of sugar.

A) x/5 =50%

x=0.5×5

x=2.5 pounds

B) x/5 =5%

x/5 =0.05

x=0.25 pounds

C) x/5 =75%

x=0.75×5

x=3.75 pounds

D) x/5 =1.5%

x/5 =0.015

x=0.075 ponds

The value for question 5 is 15 and for the question 6 is 10.

This theorem says that if two chords intersect, the product of its segments will be equal.

The question gives two circles each one with two chords. For solving the exercise, you should apply the Chord Theorem.

        Segments of chord 1 = 23 and x

        Segments of chord 2 = 23 and 15

Applying the  Chord Theorem, you have:

23*x=23*15

23x=345

x=345/23

x=15

        Segments of chord 2= x+5 and 28

        Segments of chord 2 = 2x and 21

Applying the Chord Theorem, you have:

(x+5)*28=2x*21

28x+140=42x

-42x-28x=-140

-14x=-140

x=-140/-14

x=10

Answer: $0.69

Step-by-step explanation: Divide $3.45 by 5 :)

The height of the cable from the road at a point 150 feet from the center of the bridge is 12.5 feet.

The equation for a parabolic cable is given by

y = ax^2 + bx + c

where x is the horizontal distance from the center of the bridge, y is the height of the cable from the road and a, b, and c are coefficients determined by the shape of the cable.

The height of the cable at the center of the bridge is 0

so, c = 0

The height of the cable at the towers is 80 feet

so, at x = ±300 feet, y = 80

Plugging in these two points into the parabolic equation, we can solve for a and b.

Using the formula

[tex]y = ax^2 + bx[/tex]

we have two equations:

[tex]80 = a * (300)^2 + b * 300 and 0 = a * (0)^2 + b * 0[/tex]

Solving for a and b, we find that

a = -0.000167 and b = 50

Finally, at x = 150 feet from the center,

the height of the cable from the road is

[tex]y = -0.000167 * (150)^2 + 50 * 150 = 50 - 0.000167 * 22500 = 50 - 37.5 = 12.5 feet.[/tex]

Because lines y and x are parallel, we can see that the angles that are congruent to ∠1 are:

∠5, ∠4, ∠6

We know that lines x and y are parllel lines.

So, the angles in the same quadrant of the two intersections will have the same measure, this means that:

∠1 = ∠5

∠2 = ∠6

and so on.

Also, remember that on an intersection the vertical angles have the same measure, that means that:

∠1 = ∠4

The probability that all 3 cards are clubs will be 0.0129

To find the chance that all three cards are clubs,

We can use the following formula:

[tex]P(\text{all 3 are clubs}) = \frac{\text{number of favorable outcomes}}{\text{number of possible outcomes}}[/tex]

The number of favorable outcomes is the number of ways to choose 3 clubs from the 13 clubs in the deck, which is given by the given binomial coefficient [tex]{13 \choose 3} = 286[/tex]

The number of possible outcomes is the number of ways to choose 3 cards from the deck, which is given by the binomial coefficient [tex]{52 \choose 3} = 22,!100[/tex]

Therefore, the value of the probability that all 3 cards are clubs is:

The required general solution of the differential equation in implicit form y = [tex][(3/2) * (15x + C) * x^{-3}]^{-3/2}[/tex].

The differential equation is a nonlinear equation and cannot be solved exactly by standard methods. One way to approach a solution is to try to find a substitution that transforms the equation into a separable form, where the variables can be separated and integrated separately. A common approach is to make the substitution y = v^(-2/3), which transforms the equation into:

3x^2 * (2/3) * v^(-5/3) * v' + 6x * v^(-2/3) = 15 * v^(-5/3)

Dividing both sides by v^(-5/3), we get:

3x^2 * (2/3) * v' + 6x * 3 * (2/3) * v^(1/3) = 15

This is now a separable differential equation, and we can integrate both sides to find the general solution:

∫(3x^2 * (2/3) * v' dx) = ∫(15 dx) + C

(2/3) * x^3 * v = 15x + C

v = (3/2) * (15x + C) * x^(-3)

Finally, substituting back for y = v^(-2/3), we get the general solution:

y = [tex][(3/2) * (15x + C) * x^{-3}]^{-3/2}[/tex]

This is the general solution of the differential equation in implicit form. To find an explicit form, one could solve for C using initial or boundary conditions.

The number of gigabytes of data she can use while staying within her budget is 4.2.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 6 is an equation.

We have,

Cost of the flat per month = $51.50

Cost per gigabyte = $3

g = the number of gigabytes.

Now,

Maximum cost per month = $64.10

We can make an equation.

51.50 + 3g = 64.10

Solve for g.

51.50 + 3g = 64.10

Subtract 51.50 on both sides.

3g = 64.10 - 51.50

3g = 12.6

Divide 3 into both sides.

g = 12.6/3

g = 4.2

There are 15 test scores that are 85 or greater out of a total of 30 test scores.

The third quartile, Q3, is the median of the upper half of the set of data. To determine the number of test scores that are 85 or greater, we must first find the median of the upper half of the data set. The formula to calculate the median is

Median = (n+1)/2

where n is the number of observations in the data set. In this case, n is 30. Plugging this into the formula we get

Median = (30+1)/2 = 15.5

Therefore, there are 15.5 test scores that are 85 or greater.

To calculate the number of test scores that are 85 or greater, we subtract 15.5 from 30. This gives us 14.5 test scores that are 85 or greater. Since 14.5 is not a whole number, we can round up to 15 test scores that are 85 or greater. Therefore, there are 15 test scores that are 85 or greater out of a total of 30 test scores.

The solution set of an equation is a collection of all the values that make the equation true. In mathematical terms, it's the set of all values that satisfy the equation.

The solution set can be represented graphically on a number line or coordinate plane, or it can be expressed as an ordered pair, a set of ordered pairs, or an interval. In some cases, the solution set may be empty, meaning there are no values that satisfy the equation.

The unit rate is equal to 3 dollars per book.

The unit rate can be determined by dividing the total amount of money raised by the number of books sold.

In the context of the situation, the point (6, 18) means 6 books were sold to raise a total amount of $18.

In Mathematics, the unit rate is sometimes referred to as unit price and it can be defined as the price that is being charged by a seller for the sale of a single unit of product.

In order to determine the unit price, we would use the following mathematical expression;

Unit price = Total raised/Number of books sold

Unit price = 6/2 = 12/4 = 18/6 24/8

Unit price = 3 dollars per book.

Step-by-step explanation:

The probability of selecting exactly 2 white marbles out of 5 marbles from container b is approximately 0.144 or 14.4%.

To calculate the probability of selecting exactly 2 white marbles out of 5, we can use the binomial coefficient formula, which is given by:

P(X=k) = (n choose k) × [tex]p^{k}[/tex] × [tex]1-p^{n-k}[/tex]

where n is the total number of trials (in this case, 5), k is the number of successful outcomes (in this case, 2), p is the probability of success (in this case, the probability of selecting a white marble), and (n choose k) is the binomial coefficient.

First, let's find the probability of selecting a white marble from container B, which is given by:

p = (number of white marbles) / (total number of marbles) = (300 + 1) / (300 + 100 + 1) = 301 / 401

Next, we can use the formula to find the probability of selecting exactly 2 white marbles:

P(X=2) = (5 choose 2) × p² * (1-p)⁽⁵⁻²⁾ = (10) × (301/401)² × (100/401)³ = 0.144

So the probability of selecting exactly 2 white marbles out of 5 is approximately 0.144 or 14.4%.
