nataly862011 [7]

I hope this helps you

a=4

b=9

c= -1

disctirminant =b^2-4ac

disctirminant =9^2-4.4. (-1)

disctirminant =97

x1=-9+square root of 97/2.4= -9+square root of 97/8

x2= -9-square root of 97/2.4= -9-square root of 97/8

A student has a total of 233 points on three tests. The scores on the first and second tests are the same. The third score excee

skad [1K]

Answer:

Let the scores on the first two test be x

Let score for third test be 14 exceeds second( or first) = x + 14

Total = 233

x + x + (x + 14) = 233

3x + 14 = 233

3x = 219

x = 73

Score of the third test = x + 14 = 73 + 14 = 87

Therefore, the scores are 73, 73, 87

Big Bob’s Pizza is having a special on pizza and is offering two different choices:

Anna71 [15]

Answer:

The Choice N#1 will give more pizza for your money

Step-by-step explanation:

step 1

Find the area of one slice Choice #1

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=22/2=11\ in$ ----> the radius is half the diameter

assume

$\pi =3.14$

The area of one slice is equal to

$A=(1/8)\pi r^{2}$

substitute

$A=(1/8)(3.14)(11)^{2}$

$A=47.4925\ in^{2}$

Divide the cost by the area

$4.95/47.4925=0.10\frac{\$}{in^{2}}$

step 2

Find the area of the entire personal pizza Choice # 2

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=6/2=3\ in$ ----> the radius is half the diameter

assume

$\pi =3.14$

substitute

$A=(3.14)(3)^{2}$

$A=28.26\ in^{2}$

Divide the cost by the area

$3.75/28.26=0.13\frac{\$}{in^{2}}$

therefore

The Choice N#1 will give more pizza for your money
