I got 71%, by finding out the individual percents and adding them up. Don’t know if that’s how you solve it, but it’s an answer choice, so makes enough sense to me.

Answer:

1st Question

A. 85

2nd Question  

B. 71

Step-by-step explanation:

1st Question

<em>{90 + 94 + 96 + 90} = 370/4 = 92.5</em>

<em>{95 + 99}                  = 194/2 = 97</em>

<em>{87 + 75 + 82 + 85} = 329/4 = 82.25</em>

<em>{71}                =  71/1               = 71</em>

<em>.20(92.5) +.25(97) +.30(82.25) +.25(71) = 85.175  Rounded-up = 85</em>

____________________________________________________

2nd Question

<em>.10(95) +.20(80) +.50(67) +.20(60) = 71</em>

Smallest Zero of f(x+5)=x^2+3x+30
WARRIOR [948]
Hey there
_________________
The correct answer is:
f(x+5)=(x+5)^2+3(x+5)-10

f(x+5)=x^2+10x+25+3x+15-10

f(x+5)=x^2+13x+30  and f(x+5)=x^2+kx+30 so

k=13

Now factor x^2+13x+30

Find j and k such that jk=ac=30 and j+k+b=13 so j and k are 10 and 3 so

(x+3)(x+10)

So the two zeros occur when x=-3 and -10 the smallest of which is:

x=-10

never [62]

Step-by-step explanation to answer:

So, the unit rate is $8 per yard of fabric now we need a expression which will be 13 times 8. 8 times 10 is 80 and 8 times 3 is 24. 80+24 is 104. We did associative, now we need communative. We will still get the answer to the question as we did with associative which will be 8 times 3 is 24 and 8 times 10 is 80. add that and we will get 104.

M is directly proportional to r2.when r=2,m=14.Work out the value of r when m =224
balandron [24]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ M = k x r^2

Substitute in the values:

14 = k x 2^2

Divide both sides by 2^2 to find k:

k = 3.5

Substitute the new values in:

224 = 3.5 x r^2

Divide both sides by 3.5 to find r^2

r^2 = 64

Square root it:

r = 8
