2. Higher Order Thinking Jordan needs

1 answer:

8 0

If each of her two grandfathers will match what she saves that’s 3 people, including Jordan that are splitting the cost of college. So over the course of 8 years, Jordan must save 1/3 of the total cost of college. Therefore she must save 1/8 * 1/3 of the cost each year. Equivalently stated, she must save 1/24 or $385 each year.

Answer:

The answer would be 1.33 x $10^{4}$

Step-by-step

1.28 x $10^{4}$ = 12800

5 x $10^{2}$ = 500

12800 + 500 = 13300

13300 = 1.33 x $10^{4}$ in scientific notation

Hope this helps:)

Sorry, I got the wrong answer earlier but I fixed it:)

Use Pythagorean Theorem to solve for x.<br><br> HELP ME PLZZZZ!!!! ASAP

4vir4ik [10]

Answer: $2\sqrt{22}$

Step-by-step explanation:

Pythagorean theorem: $a^{2} +b^{2} = c^{2}$ , where a and b are the legs and c is the hypotenuse.

We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.

$9^{2} +b^{2} = 13^{2}$

$81 +b^{2} = 169$

Since we don't know what $b^{2}$ is, we're going to isolate it by subtracting 81 on both sides

$b^{2} = 88$

We have to square root both sides in order to find out b (or x in the problem).

$\sqrt{b^{2}} = \sqrt{88}$

When you put this on a calculator it would result in $2\sqrt{22}$ which is the answer d in the problem.
