Please help with the question in the picture!!!

Sindrei [870]

Answer:

We have the measures:

1023 cm

2.3 m

8.72m

6430 mm

1200 mm

6.4 cm

2.5m

0.06km

Now let's write all those measures in the same unit, let's use meters.

We know that:

1cm = 0.01m

1mm = 0.001m

1 km = 1000m

Then, we can rewrie the measures as:

1023 cm = 1023*0.01 m = 10.23 m

2.3 m

8.72m

6430 mm = 6430*0.001 m = 6.430 m

1200mm = 1200*0.001 m = 1.2 m

6.4 cm = 6.4*0.01m = 0.064 m

2.5m

0.06km = 0.06*1000km = 60m

Then the order, from smallest to largest is:

6.4 cm

1200mm

2.3 m

2.5m

6430 mm

8.72m

1023 cm

0.06km

En una escuela hay 135 mujeres y la razón entre hombres y mujeres es de 7 a 9. ¿Cuántos estudiantes hay en la escuela? *

pochemuha

Answer:

There are 531.5625 students which is 531 students in the school

Step-by-step explanation:

We add the ratio numbers ( 7 + 9 = 16)

We then divide that number by 135 ( 135 / 16 = 8.4375)

After we multiply by each ratio number, ( 7 and 9).

And we end up with 531.5625, also 531 students.

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

Hay 531.5625 estudiantes, que son 531 estudiantes en la escuela.

Explicación paso a paso:

Sumamos los números de razón (7 + 9 = 16)

Luego dividimos ese número por 135 (135/16 = 8.4375)

Después, multiplicamos por cada número de razón (7 y 9).

Y terminamos con 531.5625, también 531 estudiantes.

#2 Find the segment length indicated. Assume that lines which appear to be tangent are tangent. *

gregori [183]

The angle of a tangent and a radius is a right angle.

The missing length would be the hypotenuse. Use the Pythagorean theorem to solve.

X = SQRT(12^2 + 16^2)

X = SQRT(144 + 256)

x = SQRT(400)

X = 20

Solve the equation <br><br><br> 2(x+5)=-2

erma4kov [3.2K]

Answer:

x = -6

Step-by-step explanation:

Distribute the 2 into the brackets:

2x + 10 = -2

leave the 2x alone on one side:

2x = -2 -10

2x = -12

divide both sides by 2:

x = -6
