Un alumno multiplica un número por 32 en lugar de multiplicarlo por 23, obteniendo un producto mayor en 54 al producto original. Halla la suma de cifras del producto original
Answer:
La suma de cifras del producto original es igual a 12.
Step-by-step explanation:
De acuerdo a la información proporcionada, si multiplicas un número "x" por 32 su resultado sería igual al producto original "y" más 54 dado que dice que se obtiene un producto mayor en 54 al producto original, lo que se puede expresar de la siguiente forma:
32x=y+54
Además, se puede inferir a partir del enunciado que si el número x se hubiera multiplicado por 23 el resultado habría sido el producto original que lo denominamos como "y", por lo que puedes decir que:
y=23x
Ahora puedes reemplazar y=23x en 32x=y+54 y despejar x:
32x=23x+54
32x-23x=54
9x=54
x=54/9
x=6
Finalmente, puedes reemplazar el valor de x en y=23x:
y=23x
y=23*6
y=138
Suma de cifras: 1+3+8 = 12
De acuerdo a esto, la respuesta es que la suma de cifras es igual a 12.
The sequence 18, 9, 9/2, 9/4, 9/8, ... represents the percentage of votes a particular political candidate has according to polls each day after a scandal. The sequence has a common
Answer:
r = 1/2Step-by-step explanation:
Given sequence:
18, 9, 9/2, 9/4, 9/8, ...We can see this is a GP and its common ratio is:
r = 9/8 ÷ 9/4 = 9/4 ÷ 9/2 = 9/2 ÷ 9 = 9 ÷ 18 = 1/2Common ratio
9/18=1/29/2/9=1/29/4/9/2=1/2Common ratio is 1/2

Special right triangles how do you solve them
The interior angles of any triangle must add up to 180° in measure. Right angles have measure 90°, so the missing angles in both triangles here have measure 45°.
In a 45°-45°-90° triangle, the legs and hypotenuse occur in a ratio of 1 : √2. This means
(1) x = 48 √2
(2) 88 = √2 x → x = 88 / √2 = 44 √2
You could also set up trigonometric equations to solve for x in each case:
(1) cos(45°) = 48 / x → x = 48 / cos(45°) = 48 / (1 / √2) = 48 √2
(2) cos(45°) = x / 88 → x = 88 cos(45°) = 88 (1 / √2) = 44 √2

A stepladder has an angle of elevation of 60° with the front of the house. The length of the stepladder is 24 feet. At what height does the stepladder meet the house?
Answer:
20.78 feets
Step-by-step explanation:
Based on the solution diagram attached below :
The height at which the step ladder meets the house can be obtained thus :
Using trigonometry :
Sin θ = opposite / hypotenus
Sin θ = h / 24
Sin 60 = h / 24
0.8660254 = h/24
Height, h = 0.8660254 * 24
Height, h = 20.78 feets
A student is evaluating the expression below for n=3.7.12.8+6(n-0.5) in what order should the student do the steps?
Answer:
32
Step-by-step explanation:
The given expression is :
12.8+6(n-0.5)
We need to evaluate the expression for n = 3.7
Put n = 3.7 in the above expression.
12.8+6(3.7-0.5)
= 12.8+6(3.2)
= 12.8 + 19.2
= 32
So, the value of the given expression is equal to 32.
PLEASE GIVE RIGHT ANSWER Triangle EFG has coordinates E (0, 0), F (0, 2), and G (3, 0). If ΔEFG ≅ ΔXYZ, what is the measure of XY? 1.5 units 2 units 3 units 3.5 units
Answer:
2 units
Step-by-step explanation:
Congruent triangles are those triangles, which have same shape & size (same side & angle size).
If ΔEFG ≅ ΔXYZ. And, E (0, 0), F (0, 2), and G (3, 0)
So, length EF = length XY.
Length of E (0,0) & F (0,2) is 2 units
As triangles are congruent, EF = XY
Hence, measure of XY = 2 units

Answer:
1. ∠1 = 120°
2. ∠2 = 60°
3. ∠3 = 60°
4. ∠4 = 60°
5. ∠5 = 75°
6. ∠6 = 45°
Step-by-step explanation:
From the diagram, we have;
1. ∠1 and the 120° angle are corresponding angles
Corresponding angles are equal, therefore;
∠1 = 120°
2. ∠2 and the 120° angle are angles on a straight line, therefore they are supplementary angles such that we have;
∠2 + 120° = 180°
∠2 = 180° - 120° = 60°
∠2 = 60°
3. Angle ∠3 and ∠2 are vertically opposite angles
Vertically opposite angles are equal, therefore, we get;
∠3 = ∠2 = 60°
∠3 = 60°
4. Angle ∠1 and angle ∠4 an=re supplementary angles, therefore, we get;
∠1 + ∠4 = 180°
∠4 = 180° - ∠1
We have, ∠1 = 120°
∴ ∠4 = 180° - 120° = 60°
∠4 = 60°
5. let the 'x' and 'y' represent the two angles opposite angles to ∠5 and ∠6
Given that the two angles opposite angles to ∠5 and ∠6 are equal, we have;
x = y
The two angles opposite angles to ∠5 and ∠6 and the given right angle are same side interior angles and are therefore supplementary angles
∴ x + y + 90° = 180°
From x = y, we get;
y + y + 90° = 180°
2·y = 180° - 90° = 90°
y = 90°/2 = 45°
y = 45°
Therefore, we have;
∠4 + ∠5 + y = 180° (Angle sum property of a triangle)
∴ ∠5 = 180 - ∠4 - y
∠5 = 180° - 60° - 45° = 75°
∠5 = 75°
6. ∠6 and y are alternate angles, therefore;
∠6 = y = 45°
∠6 = 45°.

Hi
Answer:Hey I go to ohva the answer is c
Step-by-step explanation:I took the test
The option (C) versi-colour, because the difference between the minimum and Q1 is greater, is the correct choice.
What is the median?A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.
We have:
A flower shop sells two types of Iris flowers: first flower and second flower.
The data is shown in the picture.
As we know, the median is the mid-value.
The min value for the first flower = 45
The min value for the second flower = 30
Q1 value for first flower = 51
Q1 value for second flower = 40
Difference between min and Q1 for first flower = 6
Difference between min and Q1 for second flower = 10
6 < 10
Thus, the option (C) versi-color, because the difference between the minimum and Q1 is greater, is the correct choice.

The given cylindrical container is used to fill the rectangular prism fish tank with water.
What is the least number of fully cylindrical containers needed to completely fill the fish tank?
The number of full cylindrical containers needed to completely fill the fish tank is 30.
What is a cylinder?In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.
We know the volume of the cylinder is given by:
[tex]\rm V = \pi r^2 h[/tex]
The volume of a cylinder:
[tex]\rm V = \pi (6/2)^2 (8)[/tex]
V = 72π cubic inches
The volume of cube v = 24×24×12 = 6912 cubic inches
A number of full cylindrical containers are needed to completely fill the fish tank:
= 6912/72π
= 30.55 ≈ 30
Thus, the number of full cylindrical containers needed to completely fill the fish tank is 30.

Determine the change to the base of a triangle if the height is tripled and the area is 12 times larger than the original.
I'll give brainliest to first answer. Help please
Answer:
If the height is tripled and the area is 12 times larger, the base would be 8 times larger.
Step-by-step explanation:
Area of Triangle = 1/2(base × height)
If the area is 1 foot and the height is 1 foot, that means the base is 2 feet, since 1 = 1/2(2 × 1)
Now, if the height is tripled and the area is 12 times larger, then the base would have to be 8 feet, since 12 = 1/2(8 × 3)
Kevin made $342 for 18 hours of work. At the same rate, how many hours would he have to work to make $247?
Answer:
13 hours
Step-by-step explanation:
First you have to find the hourly rate at which money is being earned. To do so you divided the money earn ($342) by how many hours it took to earn (18 hours).
Once you do that you're given $19.00 per hour.
Now take the money earned with the unknown time ($247) and divide it by money being made per hour ($19) and you're given 13 hours
Answer:
13
Step-by-step explanation:
First, you need to find out how much money he is making per hour. To do that, we need to do $342 divided by 18 hours. This gives us 19. We now know that Kevin is making $19 an hour. Next, do $247 divided by $19. This gives us 13. He would need to work 13 hours to make $247.
