Step-by-step explanation:

so, we find the slope-intercept form :

y = ax + b

"a" is the slope (it is always the factor of x), "b" is the y-intercept (the y-value when x = 0).

we have the slope : -6

and the given point (0, -10) gives us already the y-value when x = 0 : -10

therefore, the equation is

y = -6x - 10

In ΔQRS, the measure of ∠S=90°, the measure of ∠R=31°, and QR = 46 feet. Find the length of SQ to the nearest tenth of a foot.

ss7ja [257]

Answer:

$SQ=23.7\ ft$

Step-by-step explanation:

we know that

In the right triangle QRS

$sin(R)=\frac{SQ}{QR}$ ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

$sin(31^o)=\frac{SQ}{46}$

solve for SQ

$SQ=\frac{SQ}{46}sin(31^o)=23.7\ ft$

En Cartagena de cada 10 personas 4 tienen una enfermedad, a este ritmo ¿cuántas personas se contagiarán si son 400 personas?

vovikov84 [41]

Answer:

Se contagiarian 160 personas.

Step-by-step explanation:

Para este problema debenos usar la siguiente regla de tres:

$\frac{10(personas)}{4(enfermas)}=\frac{400(personas)}{x(enfermas)}$

Ahora, debemos despejar x de la ecuacion de arriba.

$x=\frac{400(personas)*4(enfermas)}{10(personas)}$

$x=160(enfermas)$

Por lo tanto, se contagiarian 160 personas.

A comet travels at an average speed of 273,000 km/h.

vaieri [72.5K]

Answer: 52,416,000 km

Step-by-step explanation:

If a comet travels 273,000 km/hr

1) Multiply 273,000 km by 24 hours to find how far the comet travels in one day

2) multiply the answer from 1 by 8 to determine how far it travels in 8 days

1) $\frac{273,000 km}{hr}$ * $\frac{24 hr}{1 day}$ = $\frac{6,552,000km}{day}$ (hours cancel out)

2) $\frac{6,552,000km}{day}$ *8 day= 52,416,000 km in 8 days

The comet approximately travelled 52,416,000km from when it began to travel to when it reached Earth. Hope this helped :)
