Answer:

$\Huge\boxed{x=71}$

Step-by-step explanation:

Hello There!

Remember the sum of all of the angles in a triangle is 180

So to find the missing angle we subtract the given angles from 180

180-71-38=71 so we can conclude that the missing angle (x) is equal to 71

Lady bird [3.3K]

SOLUTION

Since you can afford a down payment of $2,500, the remaining money needed to purchase the car becomes

$\begin{gathered} 20,000-2,500 \\ =17,500 \end{gathered}$

Now, we will find the simple interest on $17,500 for 48 months, which is 4 years. This becomes

$\begin{gathered} I=\frac{PRT}{100} \\ I=\frac{17,500\times4\times4}{100} \\ I=2,800\text{ dollars } \end{gathered}$

(a) What will your monthly payment be? $

We will add this interest to the $17,500 and divide by 48 months to get the monthly payment. This becomes

$\begin{gathered} 17,500+2,800=20,300 \\ \frac{20,300}{48}=422.91666 \\ =422.92 \end{gathered}$

Hence, the answer is $422.92

(b) How much will you pay in total for the car? $

To get this, we add the $20,300 (that we divided by 48 months), to the initial down payment made. This becomes

$\begin{gathered} 20,300+2500 \\ =22,800 \end{gathered}$

Hence, the answer is $22,800

We have initially found the interest as 2,800 dollars.

Hence the answer is $2,800

Seb made a jump of two and a half meters Kirsty's jump was 10 centimeters longer how long was Kirsty's jump

hoa [83]

First of all, a meter is equal to 100cm.
$1m=100cm$

Seb made a jump of two and a half meters. ( $2 \frac{1}{2}$ or $2.5$ )
Multiply 100 by 2.

$100*2=200$

Now we need the half.
What is half of 100?
50 is half of 100.

So, add 50 to the 200.

$200+50=250$

Kirsty's jump was 10 centimeters longer.

Add 10 centimeters to the 250 centimeters.
$250+10=260$

Kirsty's jump was 260 centimeters high, or 2.55 meters.
