Answer:

2160%

Step-by-step explanation:

hope this helps :)

Answer:

2160

Step-by-step explanation:

10 = 1800

2 = 1800 divided by 5 = 360

1800 + 360 = 2160

6×8=48 and 12×4=48 so it is 48 though 48 is the same

Answer

Answer:

1.

Clean machine slope: 3/2

Sudz slope: 3/2

This means they rise and run at the same rate.

2.

y intercept of clean machine: 2

y intercept of sudz: 4

this tells us that the cost for sudz is higher per pound.

3.

Clean machine because 4 pounds at sudz costs 10 dollars, while 5.5 pounds at clean machine costs 10 dollars. You get more for less at clean machine.

4.

Answer:

approximately 27 grams

Work Shown:

Half life formula

y = A*(0.5)^(x/H)

where,

A = starting amount = 30 grams

H = half life period = 90 years

x = number of years that pass by = 12

y = amount left over after x years

Let's plug the values for x, A and H into the formula to find y

y = A*(0.5)^(x/H)

y = 30*(0.5)^(12/90)

y = 27.3516746567466

y = 27 .... rounding to the nearest whole number

Step-by-step explanation:

Answer:

[tex]P(60mph\ or\ 70mph) = 0.38[/tex]

[tex]P(x>65mph) = 0.62[/tex]

[tex]P(x \le 70mph) = 0.74[/tex]

Step-by-step explanation:

Given

Speed Limits --- States

60 mph  ---------- 1

65 mph ----------- 18

70 mph ----------- 18

75 mph ---------- 13

Total -------------- 50

Solving (a): Probability of 60mph or 70mph

This is represented as:

[tex]P(60mph\ or\ 70mph)[/tex]

We only consider states with speed limits of 60 and 70mph.

So, we have:

[tex]P(60mph\ or\ 70mph) = P(60mph) + P(70mph)[/tex]

[tex]P(60mph\ or\ 70mph) = \frac{1}{50} + \frac{18}{50}[/tex]

Take L.C.M

[tex]P(60mph\ or\ 70mph) = \frac{1+18}{50}[/tex]

[tex]P(60mph\ or\ 70mph) = \frac{19}{50}[/tex]

[tex]P(60mph\ or\ 70mph) = 0.38[/tex]

Solving (b): Greater than 65mph

This is represented as:

[tex]P(x>65mph)[/tex]

We only consider states with speed limits of 70 and 75mph.

So, we have:

[tex]P(x>65mph) = P(70mph) + P(75mph)[/tex]

This gives:

[tex]P(x>65mph) = \frac{18}{50} + \frac{13}{50}[/tex]

Take L.C.M

[tex]P(x>65mph) = \frac{18+13}{50}[/tex]

[tex]P(x>65mph) = \frac{31}{50}[/tex]

[tex]P(x>65mph) = 0.62[/tex]

Solving (c): 70mph or less

This is represented as:

[tex]P(x \le 70mph)[/tex]

We only consider states with speed limits of 60, 65 and 70mph.

So, we have:

[tex]P(x \le 70mph) = P(60mph) + P(65mph) + P(70mph)[/tex]

This gives:

[tex]P(x \le 70mph) = \frac{1}{50} + \frac{18}{50} + \frac{18}{50}[/tex]

Take L.C.M

[tex]P(x \le 70mph) = \frac{1+18+18}{50}[/tex]

[tex]P(x \le 70mph) = \frac{37}{50}[/tex]

[tex]P(x \le 70mph) = 0.74[/tex]

Answer:

[tex]k = \frac{1}{2}[/tex]

Step-by-step explanation:

Given

x 2 4 6 8

y 1 2 3 4

Required

Determine the constant of proportionality (k)

The relationship between x and y is:

[tex]y = kx[/tex]

When y = 1, x = 2;

So, we have:

[tex]1 = k * 2[/tex]

[tex]2 * k = 1[/tex]

Make k the subject

[tex]k = \frac{1}{2}[/tex]

Hence, the constant of proportionality is 1/2

Answer:

Perimeter: 2(3x+6)+ 2(2x-4)

X=9

Step-by-step explanation:

In order to create the expression you just have to remember that the perimeter of a rectangle equals 2 bases plus 2 sides, so the expression would be:

Perimeter: 2(heights)+ 2(bases)

Perimeter: 2(3x+6)+ 2(2x-4)

IN order to solve for X we just have to insert the value of perimeter, which is 94:

Perimeter: 2(3x+6)+ 2(2x-4)

94=2(3x+6)+ 2(2x-4)

94= 6x+12+4x-8

94=10x+4

94-4=10x

x=90/10

x=9

So the value of x would be 9.

Answer: =1/2x+1/3

Step-by-step explanation:

The equivalent expression is 1/2x+ 1/3.

A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of expressions. The other number is x, and a number is 6 more than half of it. In a mathematical expression, this statement is denoted by the expression x/2 + 6.

Given:

1/4x+1+3/4x-2/3-1/2x

Now, solving the above expression

1/4x+1+3/4x-2/3-1/2x

= 1/4x + 3/4x - 1/2x + 1 - 2/3

= 4/4x - 2/4x + 1/3

= 2/4x + 1/3

= 1/2x + 1/3

Hence, the equivalent expression is 1/2x+ 1/3.

Answer:

the  probability that they both were sentenced to prison is 0.1740

Step-by-step explanation:

The computation of the probability is given below;

P(sentenced) is

= (367 + 68) ÷ 1043

= 0.4171.

Now

P(2 persons senteced to prison) is

= 0.4171 × 0.4171

= 0.1740

hence, the  probability that they both were sentenced to prison is 0.1740
