Rayyan made a $3000 first payment of a car The total cost of a car was $7500 he made 36 equal monthly payments to pay the car in

hammer [34]

Answer:

$125/month

Step-by-step explanation:

equation we got:

7500 = 36x + 3000

subtract 3000 from both sides

4500 = 36x

divide both sides by 36 to get x by itself

125 = x

x = 125

 so rayyan paid $125 per month

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:

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