The time it will take for 2000 mL to drain is 107 minutes.

The time it took to drain 131 mL is 7 minutes.

We have to find the time it took to drain 2000 mL.

131 millilitres drained in 7 minutes.

This means for every 7 minutes, 131 millilitres of liquid drains out.

Therefore, the time it will take for 2000 millimetres of liquid to drain can be calculated as follows:

131 mL = 7 minutes

2000 mL = ?

cross multiply

time for 2000 mL to drain = 2000 × 7 / 131

time for 2000 mL to drain = 14000 / 131

time for 2000 mL to drain = 106.870229008

time for 2000 mL to drain = 107 minutes

We have to round to the nearest minutes.

Therefore, the time it will take for 2000 mL to drain is 107 minutes.

The fewest number of points that must be plotted to have examples of all four sets of numbers is including at least one positive and one negative​ integer is 2 points

The  Numbers are generally classified into 2 main groups - Rational numbers and Irrational numbers.

All the four examples listed here are types of rational numbers only.

Now, positive integers are also called  as whole numbers and natural numbers. So, one point is enough to represent whole numbers and natural numbers.

Also, another point will be required to show integers because integers can be positive and negative and  could include fractions.

Hence, The  fewest number of points we  must plot to have examples of all four sets of numbers given are 2 points.

As we know that positive integers are types of rational numbers and  positive integers are also natural numbers and whole numbers. Therefore all the options given, are positive integers.

The correct question is What is the fewest number of points you must plot in order to have examples of all four sets of​ numbers, including at least one positive and one negative​ integer? Explain.

According to the given statement:

The computed value is significantly less than the given value.

The correct option is B.

The standard deviation serves as an indicator of how much a set of values can vary or be dispersed. The values are typically close to the set's mean when the standard deviation is low, while the values are dispersed over a wider range when the standard deviation is high.

The  computed value, 14.5

The  standard deviation, 11.1

finding the difference :

Percentage = (14.5 - 11.1)/11.1 * 100 = 30.6%

the value  is greater than 20%. ,

so,

In comparison to the given value, the computed value is significantly lower.

Answer:

The answer is below

Step-by-step explanation:

a) To complete the table of values for y = 3x - 1, we substitute the value of x into the equation and find y.

For x = -2, y = 3(-2) - 1 = -7; For x = -1, y = 3(-1) - 1 = -4

For x = 0, y = 3(0) - 1 = -1;    For x = 1, y = 3(1) - 1 = 2

For x = 2, y = 3(2) - 1 = 5;    For x = 3, y = 3(3) - 1 = 8

x:    -2      -1        0        1         2       3

y:    -7      -4       -1        2         5      8

Answer:

4c^2 - 3a^2 -7ac +6bc -ab

Step-by-step explanation:

solve first 3a( a + b + c) - 2b ( a+ b +c)

which is = 3a^2 + 3ab + 3ac - 2ab - 2b^2 -2bc

there for 4c(-a + b +c) -( 3a^2 + 3ab + 3ac - 2ab - 2b^2 - 2bc)

= -4ac-3ac +4bc+2bc -3ab+2ab + 4c^2 -3a^2

=4c^2 - 3a^2 -7ac +6bc -ab

Answer:

In this case the slope of a line perpendicular to the line whose equation is 12x+2y=-12 will be [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

A line has the form:

y = m * x + b

where:

In this case, the line has the form 12*x+2*y=-12

First, you must isolate the variable "y", in order to arrive at the form of the line detailed above:

12*x+2*y=-12

2*y= -12 -12*x

y= (-12 -12*x)÷2

y= (-12)÷2 -(12÷2)*x

y= -6 -6*x

In this case: the slope is -6 and the Y-intercept is -6.

Two lines are perpendicular when they form four equal 90º angles. For two lines to be perpendicular, they must have their slopes inverse and changed sign.

Then, in this case the slope of a line perpendicular to the line whose equation is 12x+2y=-12 will be [tex]\frac{1}{6}[/tex]

Answer:

(3,4)

Step-by-step explanation:

Find equations of both lines

Line 1: y = 1/3x + 3

Line 2: y = 2x - 2

Set then equal to each other, then solve for x:

1/3x + 3 = 2x - 2

1/3x + 5 = 2x

x + 15 = 6x

15 = 5x

x = 3

Then sub x into one of the equations (doesn't matter which one) and solve for y

y = 2x - 2

y = 2(3) - 2

y = 6 - 2

y = 4

Solution is (3,4)

Answer:

B: 30°, 78°, 72

Step-by-step explanation:

Given a [tex]\triangle ABC[/tex].

Let [tex]\angle A = x^\circ[/tex]

As per question statement, [tex]\angle B[/tex] is 18° more than twice of [tex]\angle A[/tex].

i.e

[tex]\angle B =(2x+18)^\circ[/tex]

[tex]\angle C[/tex] is 42° more than that of [tex]\angle A[/tex]

[tex]\angle C = (x+42)^\circ[/tex]

To find:

The angle measures of the triangle = ?

Solution:

We can use the angle sum property of a triangle here to find the three angles of the triangle.

As per angle sum property, the sum of all the three internal angles is equal to [tex]180^\circ[/tex].

[tex]\angle A + \angle B + \angle C= 180^\circ\\\Rightarrow x+2x+18+x+42=180^\circ\\\Rightarrow 4x+60=180\\\Rightarrow 4x=120\\\Rightarrow x= 30^\circ[/tex]

i.e. [tex]\angle A = 30^\circ[/tex]

[tex]\angle B = 2\times 30 + 18 = 78^\circ[/tex]

[tex]\angle C = 30+42 = 72^\circ[/tex]

Therefore, the correct answer is:

B: 30°, 78°, 72

Answer:

11.7 ft (11.661903789691 )

Step-by-step explanation:

Draw a right triangle. Legs are 10 ft and 6 ft, we're trying to find the hypotenuse.

We can use the Pythagorean theorem.

a^2 + b^2 = c^2

c = √a2 + √b2

  =  √(10)2 + √(6)2

  = √100 + √36

  = √136
