Solve the proportion. 3/8=m/64

Mathematics

Answer: 24

Step-by-step explanation:

3/8 = m/64

On cross multiplying, 8 goes to rhs and 64 to lhs

So 3x64 = 8m

8m = 192

m = 192/8= 24

<h2>ANSWER :</h2>

Proportion = 3/8=m/64

= on cross multiplication, 3×64=8×m

= 3×64/8=m

= m = 8×3

= m = 24

Thus, the answer is Option D . 24.

JG bisects FJH, FJG= (2x + 4)° and GJH = (3x -9)° <br> What is FJH
Kitty [74]

Hello from MrBillDoesMath!

Answer:

60

Discussion:

As JG bisects FJG,  

FJG     = GJH                =>

2x + 4 = 3x-9                => subtract 2x from each side

4         = 3x -2x - 9        => simplify

4         = x - 9                => add 9 to both sides

4 + 9   = x

x = 13

Now, FJH =

FJG        + GJH

(2x + 4)  + (3x-9) =

5x -5                             => substitute x 13

5(13) -5  =

65 - 5 =

60

Thank you,

MrB

Solve for m and n<br> I been stuck on this question for an hour
Crazy boy [7]

Answer:

m = 10 , n = 5\sqrt{2}

Step-by-step explanation:

using the cosine and tangent ratio in the right triangle and the exact values

cos45° = \frac{1}{\sqrt{2} } and tan45° = 1 , then

cos45° = \frac{adjacent}{hypotenuse} = \frac{5\sqrt{2} }{m} = \frac{1}{\sqrt{2} } ( cross- multiply )

m = 5\sqrt{2} × \sqrt{2} = 5 × 2 = 10

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

tan45° = \frac{opposite}{adjacent} = \frac{n}{5\sqrt{2} } = 1 , then

n = 5\sqrt{2}

Alex Ar [27]

Ok, primero haces estas hostilidades de considerable duración y magnitud. En el uso de las ciencias sociales, se agregan ciertas calificaciones. Los sociólogos suelen aplicar el término a tales conflictos sólo si se inician y conducen de acuerdo con formas socialmente reconocidas. Tratan la guerra como una institución reconocida en la costumbre o en la ley. Los escritores militares suelen limitar el término a las hostilidades en las que los grupos contendientes tienen el mismo poder para hacer que el resultado sea incierto durante un tiempo. Los conflictos armados de estados poderosos con pueblos aislados e impotentes suelen denominarse pacificaciones, expediciones militares o exploraciones; con los estados pequeños, se les llama intervenciones o represalias; y con grupos internos, rebeliones o insurrecciones. Tales incidentes, si la resistencia es lo suficientemente fuerte o prolongada, pueden alcanzar una magnitud que les dé derecho al nombre de "guerra".
