Answers

Answer 1

Answer:

1:3. That's the answer to this question.

Answer 2
Answer) 2:1

Step-by-step explanation:

The nation of Finlandia has 120,000 people. Of these, 20,000 are children under 16, 72,000 have jobs, 8,000 don't have jobs but are looking for work, and 20,000 are retired. With this info, calculate the labor force participation rate and the unemployment rate.

Answers

Answer: labor force participation rate  =60%

unemployment rate = 6.67%

Step-by-step explanation:

The labor force participation rate is computed as

[tex]\text{labor force participation rate}=\dfrac{\text{Total employed persons}}{\text{Total population}}[/tex]

i.e. [tex]\text{labor force participation rate}= \dfrac{72000}{120000}[/tex]

[tex]= 0.6\ or\ 60 \%[/tex]

The unemployment rate is computed as:

[tex]\text{unemployment rate}=\dfrac{\text{Number of personsdon't have jobs }}{\text{Total population}}\\\\\text{unemployment rate}=\dfrac{8000}{120000}\\\\\text{unemployment rate}=0.0667\ or\ 6.67\%[/tex]

Hence, labor force participation rate  =60%

unemployment rate = 6.67%

Un deposito de agua tiene forma de prisma rectangular con los lados de la base de 25 y 20 metros. Calcula la altura que pueda contener 1000 metros cúbicos de agua

Answers

Answer:

La altura del depósito para que pueda contener 1000 metros cúbicos de agua es 2 m.

Step-by-step explanation:

Para calcular el volumen de un prisma rectangular, es necesario multiplicar sus 3 dimensiones: longitud*ancho*altura. El volumen se expresa en unidades cúbicas.

En este caso, se conoce la longitud y el ancho, cuyos valores son 25 y 20 metros. A su vez, se sabe que el depósito de agua debe contener 1000 m³. Entonces, siendo:

Volumen= longitud*ancho*altura

Y reemplazando los valores se obtiene:

1000 m³= 25 m* 20 m* altura

Resolviendo:

1000 m³= 500 m²* altura

[tex]altura=\frac{1000 m^{3} }{500 m^{2} }[/tex]

altura= 2 m

La altura del depósito para que pueda contener 1000 metros cúbicos de agua es 2 m.

Samantha is creating concrete spheres for a weight-lifting competition. One of the spheres needs to have a weight of 350 pounds. Samantha knows that concrete weighs 150 pounds per cubic foot, in feet, of the sphere that Samantha will create? ​

Answers

The volume occupied by a 350 pound sphere is 2.33 ft³.

Equation

Equation is an expression used to show the relationship between one or more numbers and variables.

Let y represent the weight of the sphere in pounds and x represent the volume in feet³, hence:

y = 150x

For a 350 pounds sphere:

350 = 150x

x = 2.33 ft³

Step-by-step explanation:

A circle is 360 degrees

GI + GJI = 360

The arc length is the same as the angle when it is at the center

117.33 + GJI = 360

GJI = 360 - 117.33

GJI = 242.67

Answer:

A 3-member committee has to be formed from 2 teachers and 2 parents. How many combinations are possible?

Answers

Step-by-step explanation:

the answer is in the above image

The number of combinations possible if a 3-member committee has to be formed from 2 teachers and 2 parents is 4 combinations

Combination and permutation

Combinations have to do with selection compared to permutation that has to do with the arrangement.

If a 3-member committee has to be formed from 2 teachers and 2 parents, the total committee is given as:

Total committee members  = 2 + 2

Total committee members = 4 committees

If 3-member committee has to be formed from them, the number of ways this can be done is given as:

4C3 = 4!/(4-3)!3!
4C3 = 41/3!
4C3 = 4 ways

Hence the number of combinations possible if a 3-member committee has to be formed from 2 teachers and 2 parents is 4 combinations

What is the angle measure of the third angle of a triangle given the two angles below? 59 degrees and 58 degrees

Answers

Answer:

firstly a triangle has angle sum of 180°

Step-by-step explanation:

let all the three angles be x,y and z such that x+y+z =180°

let x= 58° and y =59°

the to calculate for the unknown z angle ;

make z subject of the formula

thus z= 180° -x-y

> z= (180-58-59)°

z= 180-117

z= 63°

Answer:

63

Step-by-step explanation:

59 + 58 = 117

180 - 117 = 63

To find a third angle you will subtract the sum of the two given angles from 180 because all you have to know is that all of the angles in a triangle always add up to 180°.
