URGENTT!! Susan will rent a car for the weekend. She can choose one of two plans. The first plan has no initial fee but costs $0

harkovskaia [24]

Answer:

150 miles

Step-by-step explanation:

Let

x = number of miles

Plan A: 0.60x

Plan B: 75 + 0.10x

How many miles would Susan need to drive for the two plans to cost the same?

0.60x =75 + 0.10x

0.60x - 0.10x = 75

0.50x =75

x = 75/0.50

x = 150 miles

Susan needs to drive for 150 miles for the two plans to cost the same

How do you factor 2x^3+5y^3

Pavel [41]

All you do is...
$\mathrm{Apply\:sum\:of\:cubes\:rule:\:}x^3+y^3=\left(x+y\right)\left(x^2-xy+y^2\right)$

$2x^3+5y^3=\left(\sqrt[3]{2}x+\sqrt[3]{5}y\right)\left(\left(\sqrt[3]{2}\right)^2x^2-\sqrt[3]{2}\sqrt[3]{5}xy+\left(\sqrt[3]{5}\right)^2y^2\right)$
$\left(\sqrt[3]{2}x+\sqrt[3]{5}y\right)\left(\left(\sqrt[3]{2}\right)^2x^2-\sqrt[3]{2}\sqrt[3]{5}xy+\left(\sqrt[3]{5}\right)^2y^2\right) \ \textgreater \ Refine$

$\left(\sqrt[3]{2}x+\sqrt[3]{5}y\right)\left(2^{\frac{2}{3}}x^2-\sqrt[3]{10}xy+5^{\frac{2}{3}}y^2\right)$

Hope this helps!

Ashley Stewart bought some doughnuts for $19.32 the cost of each donut was $.69. How many doughnuts more than two dozen did she

Fudgin [204]

You'd divide $19.32 by $.69, that is 28 donuts then you'd subtract 24 from 28 to find out how any MORE donuts she bought than two dozen so the answer is 4 donuts.

ivanzaharov [21]

There are 25 acres of apple trees, and 40 acres total. Thus, the probability of him NOT finding an apple tree is 1 - (25/40) = 15/40 = 37.5% or the second choice.
