What is the least possible value of 8x-13 when 9 is less than or equal to 3/4 + x?
Kruka [31]

The least possible value of 8x - 13 when 9 is less than or equal to 3/4 + x is;

53.

According to the question;

  • 9<=3/4 + x.

Therefore,

  • 9 -3/4 <= x

  • 8 1/4 <= x

Therefore, x >= 33/4.

The least possible value of x is therefore, 33/4

The expression 8x -3 becomes;

  • 8(33/4) -13

  • =66 - 13

  • = 53.

Therefore, the least possible value of 8x - 13 is;

53.

Answer:

a). 59.049°C

b). 2.1179 seconds

Step-by-step explanation:

Expression representing the final temperature after decrease in temperature of the metal from 100°C to T°C is,

T = 100(0.9)^{x}

where x = duration of cooling

a). Temperature when x = 5 seconds

T = 100(0.9)⁵

  = 59.049

  ≈ 59.049°C

b). If the temperature of the metal decreases from 100°C to 80°C

Which means for T = 80°C we have to calculate the duration of cooling 'x' seconds

80 = 100(0.9)^{x}

0.8 = (0.9)^{x}

By taking log on both the sides

log(0.8) =log[(0.9)^{x}]

-0.09691 = x[log(0.9)]

-0.09691 = -0.045757x

x = \frac{0.09691}{0.045757}

x = 2.1179

x ≈ 2.1179 seconds

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
