Answer:

D

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

a² + 12² = 13²

a² + 144 = 169 ( subtract 144 from both sides )

a² = 25 ( take the square root of both sides )

a = [tex]\sqrt{25}[/tex] = 5 → D

What is a equation of the line that passes through the point (−5,7) and is parallel to the line x+5y=10

Answers

Answer:

[tex]\displaystyle y = -\frac{1}{5} x +6[/tex]

Step-by-step explanation:

Equation of a LIne

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

We are required to find the equation of a line that passes through the point (-5,7) and is parallel to the line x+5y=10.

This information provides us the values of h=-5 and k=7. We now need to determine the value of the slope.

Two parallel lines have equal values for the slopes. The equation of the line

x + 5y = 10

Can be rearranged in such a way we can find its slope. Let's solve it for y:

5y = -x + 10

[tex]y = -\frac{1}{5}+2[/tex]

The slope of this line is -1/5 and that is the same value of the slope of our line, thus its equation is:

[tex]\displaystyle y - 7 = -\frac{1}{5} ( x + 5 )[/tex]

Adding 7:

[tex]\displaystyle y = -\frac{1}{5} ( x + 5 )+7[/tex]

Operating:

[tex]\displaystyle y = -\frac{1}{5} x + -\frac{1}{5}*5 +7[/tex]

[tex]\displaystyle y = -\frac{1}{5} x -1+7[/tex]

[tex]\boxed{\displaystyle y = -\frac{1}{5} x +6}[/tex]

Answer:

7=-1/5x+6 is the answer

2x - y = 3
x = -2y - 1

Answers

Answer:

          x  = 1,  y = - 1

Step-by-step explanation:

2x - y = 3

x = -2y - 1

2x - y = 3

2(-2y - 1) - y = 3

-4y - 2 - y = 3         {add 2 to both sides}

- 5y = 5             {divide both sides by (-5)}

 y = -1

x = -2y - 1 = -2(-1) - 1 = 2 - 1 = 1

A concert is attended by2500 people.If 47% are adult females and 32% are adults males,how many children attended?​

Answers

Answer:

use division

Step-by-step explanation:

Answer:

525

Step-by-step explanation:

first we need to work out the percentage of the children who attended  to to do this we need to add 47% with 32% which is 79%. Then you need to take away 79% from 100% which is 21%. After that you now know that 21% is the children who attended but you wanted to know how many children so to work this out you would find 21% of 2500 which would give you 525.

what is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides LHS = RHS is a common mathematical formula.

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:

y = 4x

where x represents the amount of lemonade mix in cups and

y represents the amount of water in cups.

a) lemonade cups= 16

water needed

y= 4x

y= 4 x 16

y= 64

and, in second case

y= 5x

y= 80

b) rate of change,

First, y/x= 4

and secondly y/x= 5

Todos los días por la mañana Alfonso maneja a una velocidad de 80 km/hr para llegar a su trabajo a tiempo realizando un tiempo de 42min de regreso por la tarde disminuye su velocidad a 65km/hr ¿cuanto tiempo tarda para llegar a casa

Answers

Estoy usando el traductor de en línea. No hablo mucho español.

Distancia = velocidad x tiempo
= 80 km/hr x 42 minutos
= 56 km


Tiempo = distancia / velocidad
= 56 km / 65 km/hr
= 51,6923 minutos
= 51,6923 min
= 0 horas, 51 minutos, 42 segundos

Espero que esto te ayude.

Usando proporciones, tiene-se que tardará 52 minutos para llegar a casa.

-----------------------------

Esta pregunta se resuelve por proporciones, usando una regla de tres. Considerando que la velocidad y el tiempo son inversamente proporcionales, a medida que uno aumenta y el otro disminuye, se aplica una regla inversa de tres, en la que la multiplicación está en la línea en lugar de cruzada.

-----------------------------

80km/hr tiene un tiempo de 42 min. Qual el tiempo a una velocidad de 65 km/hr?

80 km/hr - 42 min

65 km/hr - x min

Multiplicando las líneas:

[tex]65x = 80 \times 42[/tex]

[tex]x = \frac{80 \times 42}{65}[/tex]

[tex]x = 52[/tex]

Tardará 52 minutos para llegar a casa.

Complete question :

In a​ company, ​60% of the workers are men If 125 people work for the company who​ aren't men​, how many workers are there in​ all? Use pencil and paper. Show two different ways that you can solve this problem.

Answer:

313

Step-by-step explanation:

Given that :

Percentage of workers who are men = 60%

Number of workers who aren't men = 125

Hence, percentage of workers who aren't men = (100% - 60%) = 40%

Thus;

40% of workers = 125

If ;

0.4 = 125

100% of the workers x

0.4 = 125

1 = x

Cross multiply

0.4x = 125

0.4x / 0.4 = 125 / 0.4

x = 312.5

Hence, total number of workers = 313
