We can get the angle with
tan a= opposite side / adjacent side = 35ft/ 50ft=0.7, so a = arctan(0.7)=35°

What is the best way to convert metric units (I'm really bad at this...)

Vladimir [108]

Necesitas reconocer los múltiplos u submúltiplos del sistema métrico decimal si son lineales por cada nivel que avanzas multiplicas o divides con el 10
siempre y cuando la unidad de medida es el metro ese queda al centro.
Km Hm Dam m dm cm mm yo los ubico en escalera el metro queda al centro y de cualquier lugar que te posicionas,buscas a donde quieres convertir y revisas si vas a la derecha multiplicas por 10 o si vas a la izquierda divides entre 10 siempre y cuando sea un lugar a donde te vas a mover si son dos lugares es con el 100 por que 10x10 es 100 y si son tres lugares es con el 1000 porque es 10x10x10.
ejemplo 2000m convertirlos a Hm= 20 Hm dividí 2000 entre 100 porque me moví 2 lugares a la izquierda otro ejem. 100 Dam convertirlos a cm=100000 porque 100x 1000 por que avance 3 lugares a la derecha

A credit card company applies a 6% fee on all transactions under $10. You purchased coffee for $4.80. What fee amount will be ap

Romashka [77]

Answer:

$5.08

Step-by-step explanation:

Step one:

given data

We are told that a credit card company applies a 6% fee on all transactions under $10

since the cost of coffee bellow $10 that is $4.80, the 6% fee is applicable

so

=6% of 4.80

=6/100*4.80

=0.06*4.8

=$0.288

Step two:

the total fee will be

=0.288+4.80

= $5.08

PLEASE HELP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Bond [772]

Answer:

$R = \frac {3ST}{2S + T}$

Step-by-step explanation:

Given the equation;

$\frac {3}{R} - \frac {1}{S} = \frac {2}{T}$

Rearranging the equation, we have;

$\frac {3}{R} = \frac {2}{T} + \frac {1}{S}$

Lowest common multiple (LCM) of S and T is ST.

$\frac {3}{R} = \frac {2S + T}{ST}$

Cross-multiplying, we have;

$3ST = R(2S + T)$

Making R, the subject of formula;

$R = \frac {3ST}{2S + T}$
