Factor and solve the zeros for the following x^2+10x-75=0

(SAT Prep) How many distinct triangles are for which the lengths of the sides are 5,9 and n, where n is an integer and 10

Nana76 [90]

The answer is C because you can have a triangle with 5,9,n 5,10,n 9,10,n and 5,10,9

The reason why is because the sum of two sides is always larger than the value of the third side.

I hope that this helps.

What are these fractions in simplest form?

Anton [14]

$\frac{16y^{3}}{20y^{4}} = \frac{4}{5y}$
$\frac{6xy}{16y} = \frac{3x}{8}$
$\frac{abc}{10abc} = \frac{1}{10}$
$\frac{mn^{2}}{pm^{5}n} = \frac{n}{pm^{4}}$
$\frac{12h^{3}k}{16h^{2}k^{2}} = \frac{3h}{4k}$
$\frac{8x}{10y} = \frac{4x}{5y}$
$\frac{24n^{2}}{28n} = \frac{6n}{7}$
$\frac{30hxy}{54kxy} = \frac{5h}{9k}$
$\frac{5jh}{15jh^{3}} = \frac{1}{3h^{2}}$
$\frac{20s^{2}t^{3}}{16st^{5}} = \frac{5s}{4t^{2}}$

Jaina and Tomas compare their compound interest accounts to see how much they will have in the accounts after three years. They

MariettaO [177]

The question is incomplete. The complete question is :

Jaina and Tomas compare their compound interest accounts to see how much they will have in the accounts after three years. They substitute their values shown below into the compound interest formula. Compound Interest Accounts Name Principal Interest Rate Number of Years Compounded Jaina $300 7% 3 Once a year Tomas $400 4% 3 Once a year. Which pair of equations would correctly calculate their compound interests?

Solution :

It is given that Jaina and Tomas wants to open an account by depositing a principal amount for a period of 3 years and wanted to calculate the amount they will have using the compound interest formula.

<u>So for Jiana</u> :

Principal, P = $300

Rate of interest, r = 7%

Time, t = 3

Compounded yearly

Therefore, using compound interest formula, we get

$A=P\left(1+\frac{r}{100}\right)^{t}$
