Do 70Â°, 90Â°, 20Â° make a triangle and what kind

vovangra [49]

Yup. The angles of a triangle must add up to 180°—no more, no less.

These angles do: $70+90+20=160+20=180$

As for which kind, we can classify it based on the 90°-angle. Since that's a right angle, we have a right triangle. Additionally, it is scalene.

Answer:

a) 4 $x^{6}$

b) 2 $w^{4}$

Step-by-step explanation:

a) multiply the coefficients and add the exponents

(4)(1) · $x^{3+3}$ = 4 $x^{6}$

b) divide the coefficients and subtract the exponents

(14 ÷ 7) · $w^{6-2}$ = 2 $w^{4}$

Charlotte drives 64 mph for the first 3 hours of her trip and 92 mph for last 4 hours.

german

Answer:

80 mph

Step-by-step explanation:

$\boxed{\sf Distance=Speed \times Time}$

<u>First leg of trip</u>

Speed = 64 mph
Time = 3 hours

$\implies \sf Distance =64\times 3 = 192\:miles$

<u>Second leg of trip</u>

Speed = 92 mph
Time = 4 hours

$\implies \sf Distance=92 \times 4 = 368\:miles$

$\boxed{\sf Speed=\dfrac{Distance}{Time}}$

To find the average speed:

$\begin{aligned}\implies \sf Average\:speed & = \sf \dfrac{Total\:distance}{Total\:time}\\\\ & = \sf \dfrac{192+368}{3+4}\\\\& = \sf \dfrac{560}{7}\\\\ & = \sf 80\:mph\end{aligned}$
