which expression is equivalent to -4/3p - 2/5

Answer:

Option A

Step-by-step explanation:

According to the second law of thermodynamics, heat always flows from hot to cold places, unless work is done on the system. In this case the ice is colder than room temperature, and therefore the heat flows from the soda to the ice cube. The ice cube absorbs the heat, and partially melts.

Answer:

A.

x=1/2 or 0.50

The correct option is D, the value of the missing side x is 5.

If the two prism are similar, then there is a scale factor that when multiplied by the dimensions of the blue prism, we get the dimensions of the green one.

If that scale is k, then we can write:

3k = 15

Solving for k:

k = 15/3

k = 5

Now, the correspondent side to the one that measures x, has a measure of 1 unit (in the blue prism), then the value of x is:

1*k = x

1*5 = x

5 = x

The correct option is D.

Answer:The Miller family drove 379miles on Tuesday.

Step-by-step explanation:

Amount of miles driven in two days = 736  miles

Amount of miles driven on Monday = 357miles

 Therefore Amount of miles driven on Tuesday =Amount of miles driven in two days -mount of miles driven on Monday

= 736miles -357miles

Answer:

[tex]\%Percent = 30 \%[/tex]

Step-by-step explanation:

Given

[tex]Shaded = 6\ cubes[/tex]

[tex]Box = 5\ x\ 4[/tex]

Required

Determine the percentage of the shaded cubes

First, we calculate the number of boxes:

[tex]Box = 5\ x\ 4[/tex]

Express as multiplication

[tex]Box = 5\ *\ 4[/tex]

[tex]Box = 20[/tex]

This implies that there are 20 cubes in the box.

The percentage of the shaded cubes is:

[tex]\%Percent = \frac{Shaded}{Box} * 100\%[/tex]

[tex]\%Percent = \frac{6}{20} * 100\%[/tex]

[tex]\%Percent = \frac{6* 100}{20} \%[/tex]

[tex]\%Percent = \frac{600}{20} \%[/tex]

[tex]\%Percent = 30 \%[/tex]

30% were shaded

Answer:

-2/5-1

Step-by-step explanation:

6x+15y=(-15)

subtract both sides by (-6x)

now the equations becomes: 15y=(-6x)-15

divide both sides by 15, since -6 cannot evenly we just leave it as a fraction

Equation becomes y= -6/15x-1

Then simplify it down to y= -2/5x-1

Step-by-step explanation:

Step-by-step explanation:

2 + 59 -(-9) = 2+ 59 +9 = 59 + 11 = 70

After substitution in the first equation :

7x + x +21 = -19

= 8x + 21 = -19

by subtracting 21 :

8x = -19 - 21

8x = -40

by dividing over 8 :

x = -5

after substitution in the second equation :

2y = -5 + 21

2y = 16

by dividing over 2 :

y = 8

Answer:

The coordinates of the point X:

Step-by-step explanation:

Let X be the point.

As the point X is in the directed line segment from (-2,-8) to (5,-1) into the ratio of 1 to 6

i.e.

[tex]\left(x_1,\:y_1\right)\:=\:\left(-2,-8\right)[/tex]

[tex]\left(x_2,\:y_2\right)=\left(5,-1\right)[/tex]

Rise = y₂ - y₁

       [tex]= -1 - (-8)[/tex]

       [tex]= -1 + 8[/tex]

       [tex]= 7[/tex]

Run = x₂ - x₁

      [tex]= 5 - (-2)[/tex]

      [tex]= 5 + 2[/tex]

      [tex]= 7[/tex]

1 : 6 ratio means the point X lies at

[tex]\frac{1}{6+1}=\frac{1}{7}=14\%[/tex]

Thus,

rise for X [tex]=\:7\:\times \:14\%=1[/tex]

run for X [tex]=\:7\:\times \:14\%=1[/tex]

Thus, coordinates of X will be:

[tex]x = -2 + 1 = -1[/tex]

[tex]y = -8 + 1 = -7[/tex]

Therefore, we conclude that:

The coordinates of the point X:

The point (-1, -7) divide the segment from (-2,-8) to (5,-1). in the ratio 1:6.

If a point O(x, y) divides the line segment AB in the ratio of n:m, where the endpoints of the line is A(x₁, y₁) and B(x₂. y₂), the point O is at:

[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]

Given the ratio 1:6, let O(x, y) divide the segment from (-2,-8) to (5,-1). Hence:

[tex]x=\frac{1}{1+6}(5-(-2))+(-2)=-1\\\\y=\frac{1}{1+6}(-1-(-8))+(-8)=-7[/tex]

O = (-1, -7)

The point (-1, -7) divide the segment from (-2,-8) to (5,-1) in the ratio 1:6.

Answer:

The value of the car as a function of time after it was purchased is best modeled with an exponential function.

The Value of car when it is purchased =  $25,900

Step-by-step explanation:

As given,

The value at the end of the year was 17% less than its value at the beginning of the year.

⇒ value at the end of the year = (100% - 17% ) = 83% of value at the beginning of the year.

Now,

Let the Value of car when it is purchased = x

So,

Price at the end of 1 year = 83% of x = 0.83x

Price at the end of 2 year = 83% of 0.83 x = (0.83)² x

Price at the end of 2 year = 83% of (0.83)² x = (0.83)³ x

and so on

Price at the end of n years = (0.83)ⁿ x

∴ we get

The value of the car as a function of time after it was purchased is best modeled with an exponential function.

Now,

Value of car after 2 year = (0.83)² x = $17,842.51

⇒0.6889x = $17,842.51

⇒x = [tex]\frac{17,842.51}{0.6889}[/tex] = $25,900

∴ we get

The Value of car when it is purchased = x = $25,900
