AURORKA [14]

Answer:

<em>Please give brainliest</em>

You have distance =210 miles

Increase it by 20%

210+(210*0.2) = 252 miles I wrote 0.2 instead of writing 20%/100% hope you understand.

The new route is 252 miles

Time travelled = 3.5 hours

Speed=distance/time

Speed = 252/3.5 = 72 mph

enyata [817]

Answer: \frac{11}{3}\ yards

Step-by-step explanation:

Given

Laquita has 5 \frac{7}{9}\ yards of fabric i.e.

\Rightarrow \dfrac{5\times9+7}{9}=\dfrac{45+7}{9}=\dfrac{52}{9}\ yards

She used  3\ \frac{2}{3} yards to make a blouse i.e.

\Rightarrow \dfrac{3\times 3+2}{3}=\dfrac{11}{3}\ yards

Left fabric

\Rightarrow \frac{52}{9}-\frac{11}{3}=\frac{52-33}{9}\\\\\Rightarrow \frac{19}{9}\ yards

Solve the equation for an ellipse for y. Assume that y &gt; 0. y^2/a^2 + x^2/b^2 = 1
In-s [12.5K]
Multiply each term by a^2b^2:-

b^2y^2 + a^2x^2 = a^2b^2
subtract a^2x^2 from both sides
b^2y^2  = a^2b^2  - a^2x^2
Now divide both sides  by b^2

y^2 =  a^2 -  a^2x^2 / b^2  = a^2 (1 - x^2/b^2)

take positive square root ( because y > 0)

y  = a sqrt(1 - x^2/b^2)
