C. 600 x 4
if you added or subtracted,you would end up not even close to what you need.
if you divided, that would be the amount needed for 1 dog
hope this helps☼ (p.s,please can you give me brainliest, I only need 1 more before I get virtuso
Answer:
![x = 8.64^o](https://tex.z-dn.net/?f=x%20%3D%208.64%5Eo)
Step-by-step explanation:
Given
The attached rectangle
Required
Find x
To do this, we make use of:
---- angle at diagonal
Collect like terms
![11x = 5 + 90](https://tex.z-dn.net/?f=11x%20%3D%205%20%2B%2090)
![11x = 95](https://tex.z-dn.net/?f=11x%20%3D%2095)
Solve for x
![x = \frac{95}{11}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B95%7D%7B11%7D)
--- approximated
Given:
Total amount invested = $9,000
interest rates = 4% and 6%
Let x be the part of 9,000.
Note that annual return on each investment is the same.
0.04x = 0.06(9,000 - x)
0.04x = 540 - 0.06x
0.04x + 0.06x = 540
0.10x = 540
x = 540/0.10
x = 5,400
0.04x = 0.06(9,000 - x)
0.04(5,400) = 0.06(9,000 - 5,400)
216 = 0.06(3,600)
216 = 216
total interest for the year : 216 + 216 = 432
Interest = pricipal * interest rate * term
432 = 9,000 * interest rate * 1 yr
432/9,000 = interest rate
0.048 = interest rate
Interest rate would be 4.8% to get the same interest from the whole 9,000.
3 + (w² + x²) = 32 is the correct answer
