hammer [34]

Answer:

$125/month

Step-by-step explanation:

<em>equation we got:</em>

7500 = 36x + 3000

<em>subtract</em><em> </em><em>3</em><em>0</em><em>0</em><em>0</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>

4500 = 36x

<em>divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>3</em><em>6</em><em> </em><em>to</em><em> </em><em>get</em><em> </em><em>x</em><em> </em><em>by</em><em> </em><em>itself</em>

125 = x

x = 125

<em> </em><em>so</em><em> </em><em>rayyan</em><em> </em><em>paid</em><em> </em><em>$</em><em>1</em><em>2</em><em>5</em><em> </em><em>per</em><em> </em><em>month</em>

Thethree sides of a triangle measure 810 and 12 units is this a right angle?
Alja [10]

Answer:

The given triangle is NOT A RIGHT ANGLED TRIANGLE.

Step-by-step explanation:

Here, the three given sides of the triangle are:

8 units, 10 units and 12 units

Now, for any triangle to be a right angle:

by the PYTHAGORAS THEOREM:

(Base)^2 + (Perpendicular)^2  = (Hypotenuse)^2

The longest of all sides id the hypotenuse.

⇒ H  = 12 units

Let us assume, B = 8 units, P = 10 units

Now, here checking the condition:

(8)^2  + (10)^2  = 64  + 100  = 164  \neq (12)^2  = 144\\\implies (B)^2  + (P)^2  \neq (H)^2

Hence, the given triangle is NOT A RIGHT ANGLED TRIANGLE.

You deposit $1,200.00 into an account and in three years of simple interest you have $1,380. What interest rate are you receivin
Tcecarenko [31]
Since simple interest doesn't involve compounding, the same amount gets added on every year. So, the equation for the simple interest received is I = Prt, where I is the total interest, P is the original deposit (or "principal"), r is the interest rate, and t is the time passed in years.

Plugging in our values, we can solve for the interest rate:

I = Prt
\$1380 - \$1200 = (\$1200)(r)(3 years)
\$180 = (\$1200)(r)(3 years)
r = .05 = \bf 5 \%
