You estimate that a baby guinea pig weighs 3.5 ounces. The actual weight of the baby guinea pig is 3 ounces. Find the percent er

Neko [114]

Percent Error = ((measured value)/(actual value) -1)*100%
= (3.5/3 -1)*100%
≈ (1.16666667 - 1)*100%
≈ 0.1667*100%
≈ 16.67%

Help please with explain so for further questions like this

Rmember (a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)this is just alot of busy work

find f+g first then find f-g

f+g=(x-4)/(x+9)+(x-9)/(x+4)
make denomenator the same
multiply left one by (x+4)/(x+4) and right one by (x+9)/(x+9)
[(x-4)(x+4)]/[(x+9)(x+4)]+[(x-9)(x+9)]/[(x+9)(x+4)]
[x²-16]/[(x+9)(x+4)]+[x²-81]/[(x+9)(x+4)]
[x²+x²-16-81]/[(x+9)(x+4)]
[2x²-97]/[(x+9)(x+4)]

now f-g
[x²-16]/[(x+9)(x+4)]-[x²-81]/[(x+9)(x+4)]
[x²-x²-16+81]/[(x+9)(x+4)]
[65]/[(x+9)(x+4)]

now we got
$\frac{ \frac{2x^2-97}{(x+9)(x+4)} }{ \frac{65}{(x+9)(x+4)} }$
invert and multiply
$(\frac{2x^2-97}{(x+9)(x+4)})(\frac{(x+9)(x+4)}{65})$
$\frac{2x^2-97}{65}$

A retailer was given a trade discount are 15% and cash discount of 6% by the wholesaler. How much did the retailer pay for a goo

wolverine [178]

<h3>Answer: $2992.26</h3>

===================================================

Explanation:

If you're given a 15% discount, then you still have to pay the remaining 85% (because 100% - 15% = 85%)

Rewrite 85% into 0.85

The multiplier for "15% discount" is 0.85

Similarly, the multiplier for a 6% discount is 0.94; note how 100% - 6% = 94% = 0.94

When we have multiple discounts chained together like this we find the product of the multipliers. So we multiply the 0.85 and 0.94 to get

0.85*0.94 = 0.799

After chaining together the two discounts, you will have to pay 79.9% of the original value. This means the overall discount is 20.1%

Take the result of 0.799 and multiply that with the marketed price of $3745 to get the final answer

0.799*3745 = 2,992.255 which rounds to 2,992.26

What are the solutions of the equation 6x2 + x-1=0 ?

Aleksandr [31]

Answer:

<u>Options B and D</u>

Step-by-step explanation:

6x² + x - 1 = 0

6x² + 3x - 2x - 1 = 0

3x(2x + 1) - 1(2x + 1) = 0

(3x - 1)(2x + 1)

x = 1/3 and -1/2
