Raquel trabaja en un banco. El banco en el que trabaja Raquel recibió una previsión de 1 024 monedas de 10 centavos. Cada rollo de monedas de 10 centavos contiene 8 monedas. ¿Cuántos rollos de 10 centavos recibió e banco?
Answer:
El banco recibió 128 rollos de monedas de 10 centavos.
Step-by-step explanation:
Para saber cuantos rollos de monedas de 10 centavos recibió el banco, podemos dividir el total de monedas recibido entre el número de monedas por rollo.
(1 024 monedas) / (8 monedas/rollo) = (x rollos)
Donde x es el número de rollos recibido. Para calcular x se divide 1 024 entre 8
x = 1 024 / 8
x = 128
Find a formula for the described function. A rectangle has perimeter 8 m. Express the area A of the rectangle as a function of the length, L, of one of its sides. State the domain of A
The domain of the area of the given rectangle is; 0 < A < 1
How to change the subject of the formula?The subject of a formula is defined as the variable that is being worked out. This subject of formula can be easily recognized as the letter that is on its own on one side of the equals sign. For example, in the formula for the area of a rectangle A = bh, the subject of the formula is A.
Now, we are told that the rectangle has perimeter of 8 m.
The formula for the perimeter of a rectangle is;
P = 2(L + W)
We are told that the perimeter is 8 m. Thus;
2(L + W) = 8
L + W = 4
W = 4 - L
Formula for area of a rectangle is;
A = LW
Thus;
A = L(4 - L)
A = 4L - 4L²
At A = 0, we have L = 0 OR 1
The value of A cannot be zero or 1 and as such the domain of A is the;
0 < A < 1

3. George intends to drive from Atlanta to Chicago, a distance of 710
miles. He drives at an average rate of 46 miles per hour for the first 5
hours. What is his average driving rate for the remainder of the trip if
the entire trip takes 12.5 hours?
Answer:
64 mph
Step-by-step explanation:
46 x 5 = 230
710 - 230 = 480 is the distance that he has left
distance = rate x times
480 = rate x 7.5 (12.5 -5 = 7.5)
480 = r(7.5) Divide both sides b y 7.5 to find the rate
480/7.5 = [ r(7.5) ]/7.5

Summer Campers John and Ryan Are Trying To Earn Thier Archery Merit badges Each Boy has 30 Arrows and Must hit the center of the Target More Than 10 Times John hits the Center 1 Time for every 3 Arrows he Shoots. Ryan Hits the Center 2 times for every 5 arrows he shoots.which boy earns an Archery Mertit Badge
Answer:
Ryan
Step-by-step explanation:
Let's calculate the probabilities of John and Ryan hitting the target center
Let P(J) and P(R) be the respective probability representations
For John
John hits the center 1 time for every 3 tries(arrows)
Therefore
[tex]P(J) = \dfrac{1}{3}[/tex]
Out of 30 arrows (and therefore 30 attempts) the expected number of times that John can hit the center is given by
[tex]30\cdot \dfrac{1}{3} = 10\\[/tex]
Since you need to hit the center more than 10 times, John is not expected to win the merit badge
For Ryan
Ryan Hits the center 2 times for every 5 arrows (attempts)
[tex]P(R) = \dfrac{2}{5}[/tex]
With 30 arrows the expected number of times that Ryan hits the target is:
[tex]30\cdot \dfrac{2}{5} = 18\\\\[/tex]
So Ryan is expected to win the Archery Merit Badge.
Important Note
Here you have to be careful of the words you use and interpret the results with some reality checks.
Probabilities after all are based on previous trials and represent only an estimate of guarantees of future events. That's why I have repeatedly used the word expected.
After all, John maybe able to hit the center a 11th time and thus he too will earn a merit badge.

The great pyramid has base length b = 233 meters and height h = 147 meters. Assume one side of this pyramid can be represented by a triangle formed by points depicted in the following diagram. Find the area (in square meters) of one side (shaded green in the diagram).
The area of the triangular side of the pyramid is given as follows:
21,852 m².
How to obtain the area of the side of the pyramid?We consider that the side of the pyramid is triangular, hence we must consider that the area of a triangle is obtained as half the multiplication of the base by the height, that is:
Area = base x height / 2.
Considering b = 233, and dividing by the square root of 2, the coordinates of the endpoints of the base are given as follows:
(164.76, 0, 0) and (0, 164.76, 0).
Hence the length of the base is obtained using the distance between two points as follows:
Base = [tex]\sqrt{164.76^2 + 164.76^2}[/tex]
Base = 233.
The midpoint of the base has the coordinates given as follows:
(82.38, 82.38, 0).
The height is the distance between (0,0,147) and (82.38, 82.38, 0), hence it is given as follows:
Height = [tex]\sqrt{82.38^2 + 82.38^2 + 147^2}[/tex]
Height = 187.57.
Hence the area is of:
Area = 0.5 x 233 x 187.57
Area = 21,852 m².

In given fractions 8/9 is 1/36 large than 31/36
Comparing Fractions:Finding the larger and smallest fraction in between two or more fractions is known as comparing fractions.
We need to change fractions with unlike denominators into fractions with similar denominators in order to compare them. For this, we will find the denominators' Least Common Multiple (LCM).
If the denominators are the same then it is easy to compare the fractions.
Here we have
31/36 and 8/9
To find the largest fraction convert both denominators into the same
Here LCM(36, 9) = 36
Now multiply both numerator and denominators of fractions with a number to change the denominators
=> [tex]\frac{31}{36} \times \frac{1}{1} = \frac{31}{36}[/tex]
=> [tex]\frac{8}{9} \times \frac{4}{4} = \frac{32}{36}[/tex]
From the above calculations given fractions are 31/36 and 32/36
Difference = [tex]\frac{32}{36} - \frac{31}{36} = \frac{1}{36}[/tex]

X≠? F(x)=sin(2x/(1+sin(2x))
Step-by-step explanation:
a/b is invalid, when b = 0.
so, F(x) is invalid, if (1 + sin(2x)) = 0.
(1 + sin(2x)) can only be 0, if sin(2x) = -1
sin(angle) = -1
angle = 2x = 270° or 3pi/2
x = 135° or 3pi/4
so,
x <> 135° or 3pi/4
f(x) = x-4 / x^2 +13x + 36
Answer:
Step-by-step explanation:
This is a quadratic function, which is a function of the form f(x) = ax^2 + bx + c, where a, b and c are constants. The function can be written in general form as f(x) = (x-4) / (x^2 +13x + 36).
To find the roots of the function (i.e. the points at which the function intersects the x-axis), we can use the quadratic formula:
x = [-b +/- sqrt(b^2 - 4ac)] / 2a
In this case, a = 1, b = 13 and c = 36.
Substituting these values into the quadratic formula, we get:
x = [-13 +/- sqrt(169 - 4(1)(36))] / 2
x = [-13 +/- sqrt(97)] / 2
x = [-13 +/- 9.8488578] / 2
x1 = -1.1744289
x2 = 11.1744289
Therefore, the roots of the function are x1 = -1.1744289 and x2 = 11.1744289.

Amina runs a small café at the festival and her piece of ground
is 6.0 m x 5.0 m. She wants to put up a tarp roof to shelter
the entire area. The angle at the central top of the roof has to be 90°.
What is the minimum length and width of the tarp in order to
cover the whole roof?
Answer:
The minimum length and width of the tarp would be the diagonal length of the café's piece of ground. To find this length, you can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. In this case, the café's piece of ground forms a right triangle, with one side measuring 6.0 m and the other side measuring 5.0 m. So, to find the length of the hypotenuse, we can use the formula: c = √(a^2 + b^2) where c is the length of the hypotenuse and a and b are the lengths of the other two sides. Plugging in the numbers, we get: c = √(6.0^2 + 5.0^2) = √(36 + 25) = √(61) = 7.81 m
So, the minimum length and width of the tarp would be 7.81 m.
In △ABC, the length of median BM is half the length of side AB and ∠ABM measures 40°. Find m∠ABC.
Answer:
m∠ABC = 180.
Step-by-step explanation:
In a triangle, the median to the side opposite the largest angle bisects that angle.
Since BM is a median, it bisects ∠C, the angle opposite side AB.
Let's call the angle opposite side AB angle x, so x/2 = 40.
Therefore, x = 80
Since a triangle has 180 degree, then if we add all the angles in the triangle we get:
m∠ABC = m∠BAC + m∠BCA + m∠CAB = x + (180-x) + (180-x) =180
So m∠ABC = 180

What are the types of solutions a system of linear equations have?If a system of equations only contains two linear equations with two variables, the system's equation can be graphed, the graph will have two straight lines, and the intersection point(s) of those lines will be the system's solution.
There are only three matching forms of solution for a given system of equations because there are only three different ways that two straight lines in the plane can graph.
Let, The rectangle be x, the triangle by y, and the star be z.
Therefore,The three linear equations are,
x + 3y + z = 57...(i)
12x + 5y = 234...(ii)
8x - 6x + 3x = 60...(iii)
5x = 60.
x = 12.
Putting the value of x in eqn(ii) we have,
12(12) + 5y = 234.
144 + 5y = 234.
5y = 90.
y = 18.
Now, Putting the value of x and y in eqn(i) we have,
12 + 3(18) + z = 57.
12 + 54 + z = 57.
z = - 9.
So, The value of the expression z(y + z + x) + x(z + y + y) is,
= - 9(18 - 9 + 12) + 12(- 9 + 18 + 18).
= - 9(21) + 12(27).
= - 189 + 324.
