Answer:

RT = 17.9

RS = 9.7

m<T = 33°

Step-by-step explanation:

sin R = opp/hyp

sin R = ST/RT

sin 57° = 15/RT

RT = 15/sin 57°

RT = 17.9

cos R = adj/hyp

cos R = RS/RT

cos 57° = RS/17.88544939

RS = 17.88544939 × cos 57°

RS = 9.7

m<R + m<S + m<T = 180°

57° + 90° + m<T = 180°

m<T = 33°

Answer: x=6, y=-6

Step-by-step explanation:

-4x + -2y = -12 (a)

4x + 8y = -24 (b)

(a)+(b)= -4x+4x+8y+(-2y)=-12+(-24)

                                 6y= -36

                                   y=-6

put y=-6 into formula (a)

-4x+12=-12

-4x= -24

x=6

The old box of cereal contained 24.5 ounces.

Take 30% of the original box of cereal.

To find 30% of a number, multiply the number by 0.3.

35 ounces x 0.3 = 10.5 ounces

Subtract 10.5 ounces from 35 ounces.

35 ounces - 10.5 ounces = 24.5 ounces

Answer: The old box of cereal contained 24.5 ounces.

When you take a single number and multiply it by several, you are multiplying. A 5 multiplied by a 4 results in 20 (5 + 5 + 5 + 5). We multiplied the number five by four times. Due to this, multiplication is occasionally referred to as "times."

Yes, it is possible that you have to travel a greater distance to reach point b than to reach point a.

A straight line is a geometric concept that refers to a line that extends indefinitely in two directions without any curvature. It is the shortest distance between two points in Euclidean space and it is represented by an equation in the form of y = mx + b, where m is the slope and b is the y-intercept.

As both destinations, A and B are measured as the crow flies, or in a straight line, and you are able to travel only in straight lines along the main directions (north, south, east, and west), it is possible that the path to point B includes more turns or obstacles, such as buildings or rivers, that require you to travel further in order to reach the destination.

That's why it is possible that you have to travel a greater distance to reach point B than to reach point A.

Therefore Yes, it is possible that you have to travel a greater distance to reach point b than to reach point a.

If the daily prices are $1.50 for children and $2.00 for adults , then the number of adults swam at public pool is 302  and number of children who swam at public pool is 258  .

let the number of children swam at swimming pool be = c ;

let the number of adults swam at swimming pool be = a ;

the total number of person who used the swimming pool is = 560 ;

the equation is ⇒ c + a = 560 ...equation(1) ;

the price for 1 child is $1.50 and price for 1 adult is = $2 ;

the total money collected can be written as :

= (price of children tickets)×(number of children that swam)+(price of adults tickets)×(number of adults that swam) ;

⇒ 1.5c + 2(560 - c) = 991  ;

⇒ 1.5c + 1120 - 2c = 991 ;

⇒ -0.5c = 991 - 1120  ;

⇒ -0.5c = -129 ;

⇒ c = 129/0.5 = 258 ;

So , adults (a) = 560 - 258 = 302 ;

The focal radius of the ellipse of which the two foci seat are:  

An ellipse can be represented in the standard form as (x/a)² + (y/b)² = 1, where (a,b) is the center of the ellipse and a and b are the semi-major and semi-minor axes respectively.

Given the equation of the ellipse:

16x² + y² - 128x - 20y + 292 = 0

To put it in the standard form, we have to complete the square and then divide both sides by the constant on the right-hand side.

First, we complete the square by adding and subtracting (128/2)² and (20/2)² respectively:

16x² - 128x + (128/2)² + y² - 20y + (20/2)² = 292 + (128/2)² + (20/2)²

Then, we divide both sides by 292:

(16x² - 128x + (128/2)²)/292 + (y² - 20y + (20/2)²)/292 = 1

On simplifying we get:

(4x - 8)²/144 + (y - 10)²/36 = 1

Now we have the standard form of the equation of the ellipse and we can find the semi-major and semi-minor axis and the center of the ellipse.

The semi-major axis is equal to the square root of the coefficient of x squared (144) and the semi-minor axis is equal to the square root of the coefficient of y squared (36).

The center of the ellipse is (-8, 10) and the semi-major and semi-minor axis are 12, 6 respectively.

The focal radius is the distance between the center and the focus. The focal radius is equal to the square root of the semi-major axis squared minus the semi-minor axis squared.

Focal radius = √(a² - b²) = √(144-36) = √108 = 6√3

The two foci of the ellipse sit on the x-axis, symmetric about the center of the ellipse. The foci are located at (-8 ± 6√3, 10).

Therefore, the two foci of the ellipse are at (-8 + 6√3, 10) and (-8 - 6√3, 10).

The sum of money that can be divided between two parts = Rs 200

Adding three times the smaller part to half of the larger part then its will always be less than Rs 200

Let The smaller part = Rs S

The larger part = Rs L

The sum of parts = Rs 200

Larger + Smaller = Rs 200

L+S=200---------------(1)

And, Adding three times the smaller part to half of the larger part then the result will always be less than Rs 200

(3S+1/2× L)-200 = 0

3S+ L/2=200                    

6S+L=400 --------(2)

Solving eq 1 and eq 2

(6S+L)-(L+S)=400 - 200

(6S-S )+(L-L )=200

5S+0=200

S = 200/4

∴Smaller = S=Rs40

Now, Plug the value of S into eq 1

L+S = Rs 200

L+40 = Rs 200

L = 200 - 40

L = Rs 160

Larger = L= Rs160

Hence, the larger part is Rs 160 and the smaller part is Rs 40

The values of y are 0, 3 and 7/4 respectively. The solution has been obtained by using the substitution method.

What is substitution method?

The substitution approach is one of the algebraic methods for resolving simultaneous linear equations. It entails swapping any variable to change its value from one equation to another. By doing this, two linear equations are merged into one straightforward equation with one variable.

We are given a rule which is that y= x-1/4

Various values of x are given

So, in order to find the values of y, we will use the substitution method.

When x=1/4, then

⇒y=1/4-1/4

⇒y=0

When x=13/4, then

⇒y=13/4-1/4

⇒y=12/4

⇒y=3

When solving absolute value inequalities involving the greater than symbol (>) or greater than or equal to symbol (≥), we have to consider two cases absolute value expression greater than the constant and less than the constant.

The absolute value expression is greater than the constant:

|x| > c or |x| ≥ c

In this case, we can split the solution set into two parts: x < -c and x > c. The solution is all real numbers less than -c and all real numbers greater than c.

The absolute value expression is less than the constant:

|x| < c or |x| ≤ c

In this case, we can split the solution set into two parts: -c < x < c. The solution is all real numbers between -c and c, excluding -c and c.

For example, consider the inequality |x| > 2. The solution is x < -2 or x > 2, so the solution set is {x | x < -2 or x > 2}.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of toy cars produced by Company A be A

Let the number of toy cars produced by Company B be B

The y-values for h(x) are: -27, -13, -3, 3, 5, 3, -3

The range of h is the set of all these y-values. We can see that the lowest y-value is -27 and the highest y-value is 5. So, the range of h is {-27,-13,-3,3,5}

Therefore, the range of h is from -27 to 5.

All of the zeros of f(x) algebraically are; x = -3, x = -1/2, x = -5/2

The zeros of a polynomial p(x) are defined as all the x-values that make the polynomial equal to zero.

The polynomial is;

f(x) = 4x³ + 24x² + 41x + 15

To find the x-intercept, we will equate the polynomial to zero to get;

4x³ + 24x² + 41x + 15 = 0

Since (x + 3) is a factor, then we can factorize the polynomial as;

(x + 3)(4x² + 12x + 5) = 0

Rewriting the quadratic term gives;

(x + 3)(4x² + 2x + 10x + 5) = 0

(x + 3)(2x(2x + 1) + 5(2x + 1)) = 0
