the ratio of adults to children is 7:3. based on this ration, if there was 370 people how many where children

1 answer:

6 0

In a ratio of 7:3, for every 7 adults you have 3 children. So 30% of the total are children. I.e. if you have 10 people .7 times (10) are adults or 7 and .3 times (10) are children or 3. So for 370 people, .3 times 370 are children, or 111.

Calcula el lado y el área de un poligono regular 12 lados sabiendo que su radio es de 7,727dmy su apotema de 7,464

Vika [28.1K]

Answer:

$L=3.999 \: dm$

$A=183.4581\:dm^{2}$

Step-by-step explanation:

La relación del apotema y el lado de un dodecágono regular está dada por la siguiente ecuación:

$a_{p}=L\frac{2+\sqrt{3}}{2}$

Sabiendo que la apotema es 7.464 el lado sera:

$L=\frac{2*a_{p}}{2+\sqrt{3}}$

$L=\frac{2*7.464}{2+\sqrt{3}}$

$L=3.999 \: dm$

Por otro lado el area de un dodecágono regular esta dada por:

$A=6a_{p}L$

$A=6*7.646*3.999$

$A=183.4581\:dm^{2}$

So the blue point is -10 but then it says it’s far from 10 confused

statuscvo [17]

This number line is counting by 5's. Each dash is valued 5 numbers.

The blue point would be -10. Even though on this number line -10 visually looks "close" to 10, it isn't. They are 20 numbers apart.

Hope this helped!
