Answer:

2

Step-by-step explanation:

Rearrange to same form:

2y = -5x + 10

y = -5/2x + 10

ay = -5x + 4

Parallel lines have no intersection and solution, thus a = 2

Answer:

Step-by-step explanation:

For there to be no solution the lines must be parallel and have different y intercepts. To be parallel they must have the same slope.

Solving each for y

y=(10-5x)/2 and y=(4-x)/a

So the slopes are

-5/2 and -1/a, if they are equal

-5/2=-1/a

-5a=-2

a=2/5

Answer:

diameter = 2.5 feet

Step-by-step explanation:

Circumference of a circle is given as C = πd

Circumference of the tree trunk = 7.85 ft

π = 3.14

Diameter of the tree trunk = d

Thus:

7.85 = 3.14*d

Divide both sides by 3.14

7.85/3.14 = 3.14*d/3.14

2.5 = d

d = 2.5 ft

Answer:

45%

Step-by-step explanation:

let's say 20 is 100%

10 is 50%

then 10 divided by 5 (to get 10%) is 2

so 1 is 5%

then we wanna get 9 so we do 10-1 which equals the percentages 50-5 to get 45%

Answer:

£268.8

Step-by-step explanation:

192 = 100%

19.2= 10%

19.2 x 4 = 76.8

76.8 = 10%

76.8 + 192 = 268.8

Answer:

The rainfall on Saturday was of 60 mm.

Step-by-step explanation:

Average rainfall:

The average rainfall is given by the total rainfall divided by the number of days(7). So

If the records of daily rainfall from Sunday to Friday were 45 mm, 22 mm, 28 mm, 36 mm, 30 mm and 24 mm

On Saturday it was of x mm. So

[tex]35 = \frac{45 + 22 + 28 + 36 + 30 + 24 + x}{7}[/tex]

[tex]185 + x = 245[/tex]

[tex]x = 245 - 185[/tex]

[tex]x = 60[/tex]

The rainfall on Saturday was of 60 mm.

Answer: Find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon. Round to the nearest tenth, if necessary. 24 b 15, 345 24, 156 7.5, 172.5 15, 165​

Step-by-step explanation:  sum, S, of the measure of the interior angles of a polygon with n sides is: ... The sum of the interior angles of a 24 -gon is 3960. ... angles of a polygon is (n−2)⋅180 , where n is the number of sides. ... Each exterior angle measures 36024=15 . ... The sum of the 24 interior angles is then 24⋅165=3960 .

Answer:

Population A

Step-by-step explanation:

Usually in statistics, the more we increase the sample size, the more the standard deviation decreases. Similarly, the more we decrease the sample size, the more the standard deviation increases.

Finally, the more the standard deviation or error of Variance the lesser the power to detect an effect.

In this question, Population B has a greater standard deviation and thus would not have as much power as Population A in detecting an effect.

Thus Population A with standard deviation of 2.3 will have highest power to detect an effect.

Answer:

m<B = 93°

Step-by-step explanation:

Based on the inscribed quadrilateral theorem, the opposite angles of a cyclic quadrilateral are supplementary.

Thus:

m<B + m<D = 180°

Substitute

m<B + 87° = 180°

m<B = 180° - 87°

m<B = 93°

By applying Cramer's rule as solution method, the solution of the linear system 3 · x + 2 · y = 5 and x + 3 · y = 4 is equal to the set (x, y) = (1, 1).

Determinants are constructions studied in linear algebra and related to matrices, one of the most common applications of determinants is the solution of linear equations, whose simplest form is known as the Cramer's rule.

Now we proceed to use this rule to get the solution of the linear system:  

[tex]x = \frac{\left|\begin{array}{cc}5&2\\4&3\end{array}\right| }{\left|\begin{array}{cc}3&2\\1&3\end{array}\right|}[/tex]

[tex]x = \frac{(5)\cdot (3)-(4)\cdot (2)}{(3)\cdot (3) -(1)\cdot (2)}[/tex]

x = 1

[tex]y = \frac{\left|\begin{array}{cc}3&5\\1&4\end{array}\right| }{\left|\begin{array}{cc}3&2\\1&3\end{array}\right|}[/tex]

[tex]y = \frac{(3)\cdot (4) - (5)\cdot (1)}{(3)\cdot (3) - (1)\cdot (2)}[/tex]

y = 1

By applying Cramer's rule as solution method, the solution of the linear system 3 · x + 2 · y = 5 and x + 3 · y = 4 is equal to the set (x, y) = (1, 1).

Answer: The slope is 0

Answer:

A U B= 1,2,3,4,6,10,11

Step-by-step explanation:

because A union B is all number from set A and set B together without repeating

Answer:

A right triangle contains a right angle, so it must have two sides that are perpendicular. If the slopes of two sides can be shown to be negative reciprocals of each other, then it can be concluded that a right angle is formed. If a triangle contains a right angle, then it is a right triangle

Step-by-step explanation:

to determine if a triangle is a right triangle using slopes, you have to understand perpendicular slopes/negative reciprocals.

You can calculate the slope of all 3 sides of the triangle and if two of the slopes are negative reciprocals, then those two lines intersect creating a right angle/right triangle.

Let's say there's triangle ABC.

If the slope of AB is 1/2

and the slope of BC is 2/5

and the slope of CA is -2/1

then AB and CA intersect resulting in a right angle (triangle).
