Answer:
1/12
Step-by-step explanation:
The whole circumference (i.e complete circle) is an arc which measures 360°
in our case, it is given that our arc measures only 30°
the fraction of our arc of 30° to the complete circle of 360° is
30/360
= 3/36
= 1/12
Part A
1 day = 1/4 hours of practice
7 days = 7/4 hours of practice (multiply both sides by 7)
1 week = 7/4 hours of practice
1 week = (4+3)/4 hours of practice
1 week = (4+3)/4 hours of practice
1 week = (4/4)+(3/4) hours of practice
1 week = 1+(3/4) hours of practice
1 week = 1 & 3/4 hours of practice
side note: 1 & 3/4 = 1.75
=======================================
Part B
Take the result from part A, and multiply it with 60
So we'll have 60 times 1&3/4 on the left side on the first line, then 60*(1+3/4) on the right side of this same line.
The rest of the lines look like this
(60*1) + (60*3/4)
60 + 60*3/4
60 + 180/4
60 + 45
105 minutes
Answer:
Step-by-step explanation:
Well so it is asking you the statements and reasons and there is a select button it would be..... Hold on think about the letter formation. Just choose your best answer you think it is because if we are telling you thats cheating. But look above what I said. Think of the letter formation and quardinate with the question. I am speeding and yes I know I spelt it wrong.
To find the area<span> of a regular </span>polygon<span>, you use an apothem, which is a segment that joins the </span>polygon's center to the midpoint of any side and that is perpendicular (<span> angle of 90°) </span>to that side
Answer:
El lote menor tendrá 1800 m^2
El lote mayor tendrá 2400 m^2
Step-by-step explanation:
Definamos las variables:
M = superficie del lote mayor
m = superficie del lote menor.
Sabemos que el terreno tiene en total 4200 m^2
Entonces:
M + m = 4200 m^2.
Y queremos que el lote menor sea 3/4 del lote mayor, entonces:
m = (3/4)*M
Podemos reemplazar esto en la ecuación de arriba para obtener:
M + ( (3/4)*M) = 4200 m^2.
Y ahora podemos resolver esto para M
M + (3/4)*M = 4200m^2
M*(1 + 3/4) = 4200m^2
M*(4/4 + 3/4) = 4200 m^2
M*(7/4) = 4200m^2
M = (4/7)*(4200m^2) = 2400m^2
Esto significa que la superficie del mayor lote es 2400 m^2
Y la superficie del menor se puede obtener con la ecuación:
m = (3/4)*M
m = (3/4)*2400m^2 = 1800m^2
La superficie del lote menor es 1800m^2
