Crawling Crayfish!

boyakko [2]

Answer: Crayfish, 25 s

Step-by-step explanation:

Given

The length of race is 60 cm

Flicker gets a 10 cm head-start

Cray fish covers 6 cm in 5 s i.e. its speed is

$\Rightarrow \dfrac{6}{5}=1.2\ cm/s$

Flicker covers 4 cm in 5 s, its speed is

$\Rightarrow \dfrac{4}{5}=0.8\ cm/s$

Time taken by Cray fish to cover the race is

$\Rightarrow t_1=\dfrac{60}{1.2}\\\\\Rightarrow t_1=50\ s$

Time taken by flicker to cover race with 10 cm head start

$\Rightarrow t_2=\dfrac{60-10}{0.8}\\\\\Rightarrow t_2=62.5\ s$

Time taken by crayfish is less. Hence, crayfish wins the race

When they both covers the same distance, they tied momentarily i.e.

$\Rightarrow 1.2t=10+0.8t\\\Rightarrow 0.4t=10\\\\\Rightarrow t=\dfrac{10}{0.4}\\\\\Rightarrow t=25\ s$

After 25 s, they tied the race.

Find m3 if m5 = 38° and m6 = 62°.

geniusboy [140]

M5 minus M6 will get M1
So 62 - 38 = 24
24 x 3 = 72
So M3 is 72

Multiplying Polynomials//<br><br> Multiply- <br> 12x^4 (-5/6x^3y^2)

ElenaW [278]

$12 x^{4} * (- \frac{5}{6} x^{3} y^{2})$
Now multiple the coefficients and add the exponents with common bases
$12 * - \frac{5}{6} = -10 \\ x^{4} + x^{3} = x^{7}$
Now write your final expression
$-10 x^{7} y^{3}$
Hope I helped!
