32476-13899= 18577

De acuerdo a esto, la respuesta es que la orquesta ahorraría S/ 18577 al comprar un piano digital en vez de un piano de cola.

Step-by-step explanation: Do You Want Me To Find All The Values ?

Parallel lines intersected by a common transversal form 8 angles

The required values of y and x are;

The reasons why the above values are correct are given as follows:

Given the lines are parallel lines cut by a common transversal, we have;

Angles with measure (2·y - 1)° and (9·x - 38)° are same side interior angles

Angles with measure (4·x + 23)° and (2·y - 1)° are alternate interior angles

Which gives;

(2·y - 1)°+ (9·x - 38)° = 180°...(1)

(4·x + 23)° = (2·y - 1)°...(2)

From equation (1), we get;

y = 109.5 - 4.5·x

From equation (2), we get;

y = 2·x + 12

The common solution is given by; 109.5 - 4.5·x = 2·x + 12

From 109.5 - 4.5·x = 2·x + 12, we get;

x = 15,  

6) (9·x + 42)° and 15·x° are vertical angles, and therefore are equal

(9·x + 42)° = 15·x°

∴ x = 7

(4·y - 13)° and (9·x + 42)° are supplementary, therefore

(4·y - 13)° = (9·x + 42)°, which gives;

(4·y - 13)° = (9×7 + 42)° = 105°

7) (3x + 11) + (x + 21) = 180

∴ x = 37

(14·y - 4)° = 3x + 11 = 3 × 37 + 11 = 122°

8) (13·x - 33) = 10·x

∴ x = 11

10·x + 5·y = 180

10 × 11 + 5·y = 180

[tex]y = \dfrac{70^{\circ}}{5} = 14^{\circ}[/tex]

9) (27·x + 4) + (8·x + 1) = 180

∴ x = 5

y + 10 = 8·x + 1 = 8 × 5 + 1 = 41

y = 41 - 10 = 31

10) 16·x - 4 = 9·x - 6 + 58 = 9·x + 52

7·x = 56

x = 8

11) (6·x - 58)° + (x + 8)° = 90°

7·x - 50 = 90

7·x = 90 + 50 = 140

[tex]x = \dfrac{140}{7} = 20[/tex]

12) 7·x - 7 = 3·x + 45°

4·x = 52

[tex]x = \dfrac{52}{4} = 13[/tex]

x = 13°

(3·x + 45)° + 63° + (y - 6)° = 180°

(3×13 + 45)° + 63° + (y - 6)° = 180°

147 + (y - 6)° = 180°

Answer:

The answer is 90 mm squared

Step-by-step explanation:

First off, Surface Area is the combined areas of the 2D shapes that make up a 3D shape. The formula for finding the area of a triangle (the 2D shape that makes up most of a pyramid) is a = 1/2 bh, which is basically area = 1/2 base (the un-slanted line) * the height, or the middle line.

Since there are 4 triangles, you would multiply this by 4 after solving, so

sa = 4(1/2bh)

Putting the numbers in, you'd get

sa = 4(1/2*5*9)

To solve:

sa = 4(1/2*45)

sa = 4(22.5)

sa = 90mm^2

Answer:

h = 4.22 cm

Step-by-step explanation:

Mathematically, we have the volume of a cylinder as;

V = pie * r^2 * h

We have it that the radius is 6 cm

V = pie * 6^2 * h

for the sphere, we have it that;

V = 4/3 * pie * r^3

V = 4/3 * pie * 4.5^3

We can proceed to equate both volumes;

pie * 6^2 * h = 5/3 * pie * 4.5^3

pie on both sides cancel out

6^2h = 5/3 * 4.5^3

36h = 151.875

h = 151.875/36

h = 4.22 cm

Answer:

Step-by-step explanation:

since RS || VU   ( parallel to )   then the angle V is equal to ∠ VRS , also we are given that ∠VRT = 71°  so subtract  ∠VRT from ∠VRS

103° - 71° = 32°

so ∠TRS = 32°

next find ∠U,  we know that ∠U + ∠VRT= 180°  ( b/c they are supplementary )

we are also told that  ∠VRT = 71°

∠U = 180 - 71

∠U = 109°

Since RS || VU (parallel to) then the angle V is equal to VRS, also we are given that VRT = 71°

So subtract VRT from VRS,

103° -71° = 32°

So, TRS = 32°

next find U, we know that ZU + ZVRT= 180° (b/c they are supplementary)

We are also told that <VRT = 71"

U = 180° - 71°

U = 109° is the answer.

Answer:

Step-by-step explanation:

The sampling method employed in the given example is convenience sampling.

Convenience sampling is a non-probability sampling technique where the sample is selected based on its accessibility and convenience. In this case, the post office manager selected three delivery people from the total of 11 available. This selection was based on convenience, as they were already working for the post office.

The population in this scenario consists of all the customers the post office manager works with. Let's denote this population as N.

The post office manager used convenience sampling to select a subset of the population to participate in the study. The size of the sample is not explicitly mentioned, but we can assume it is the total number of customers on the three selected delivery routes. Let's denote the sample size as n.

Since convenience sampling does not involve random selection, the sample selected may not be representative of the entire population. The customers on the selected delivery routes may not be a fair representation of all the post office customers. This introduces a potential sampling bias.

It's important to note that convenience sampling can be quick and easy to implement but may not provide reliable or generalizable results. In this case, the post office manager may obtain information about customer satisfaction from a limited group, potentially leading to skewed or unrepresentative findings. For a more accurate and representative study, a different sampling method, such as random sampling or stratified sampling, could be employed.
