Usando conceptos de fracciones y proporciones, se encuentra que trabajó $\mathbf{\frac{1}{8}}$ del día.

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

Esta pregunta se resuelve por proporciones, usando una regla de tres

Un día completo tiene 24 horas
¿Cuál es la fracción correspondiente a 3 horas de un día?

1 dia - 24 horas

x dias - 3 horas

Aplicar multiplicación cruzada:

$24x = 3$

$x = \frac{3}{24}$

$x = \frac{1}{8}$

Entonces, $\frac{1}{8}$ es la fracción.

What is the 23rd term of the arithmetic sequence where a1 = 8 and a9 = 48?

yKpoI14uk [10]

$a_1=8$
$a_2=a_1+d=8+d$
$a_3=a_2+d=(8+d)+d=8+2d$
$a_4=a_3+d=(8+d)+2d=8+3d$
...
$a_9=8+8d=48\implies d=5$
$a_{10}=8+9d$
...
$a_{23}=8+22d=118$

m∠R = 27.03°

Solution:

Given In ΔQRP, p = 28 km, q = 17 km, r = 15 km

To find the measure of angle R:

Law of cosine formula for ΔQRP:

$r^{2}=p^{2}+q^{2}-2 pq \cos R$

Substitute the given values in the above formula.

$(15)^{2}=(28)^{2}+(17)^{2}-2 (28)(17) \cos R$

$225=784+289-952 \cos R$

$225=1073-952 \cos R$

Switch the given equation.

$1073-952 \cos R=225$

Subtract 1073 from both side of the equation.

$-952 \cos R=-848$

Divide by –952 on both sides.

$$ \cos R=\frac{106}{119}$

$$ R=\cos^{-1} \left(\frac{106}{119}\right)$

$R=27.03^\circ$

Hence m∠R = 27.03°.

Len walks 3/10 mile in the morning. He walks 2/5 mile in the afternoon to a friends house. Len says that he walks a total of 5/1

andre [41]

No he walks 7/10 of a mile
you have to make 2/5 have a common denominator with 3/10
so 2×2=4 (numerator)
2×5=10 (denominator)
4/10+3/10= 7/10
since you only add the numerator because the denominator makes it a like term

The area of jacksons rectangular garden is 64 square ft. If the length of the

Gekata [30.6K]

Hi,

First we must go back to the formula of the Area of a 2d figure which is L*W or Length times the Width. So, we could divide 64 by 16.

64/16 = 4

The answer is 4.
