Step-by-step explanation:

The value of 'k' for the given system of equation that coincides  is 4

k=4

Given :

System of equations

[tex]2x+y=40 \\kx+2y=80[/tex]

The given equation is in the form of ax+by=c

When the two lines coincides then

[tex]\frac{a_1}{a_2} =\frac{b_1}{b_2} =\frac{c_1}{c_2}[/tex]

Lets make the coefficients proportional to each other and then solve for k

[tex]\frac{2}{k} =\frac{1}{2} =\frac{40}{80} \\\frac{2}{k} =\frac{1}{2} =\frac{1}{2} \\\\\frac{2}{k} =\frac{1}{2} \\4=k\\k=4[/tex]

The value of k from the given system of equation is 4

When the line coincides then the value of k is 4

Answer:

60

Step-by-step explanation:

[tex]180 - 2(60) = 60[/tex]

Answer:

60°

Step-by-step explanation:

A triangle with two 60° angles has another 60° because 180-(60+60)=180-120=60°.

Also, this is an equilateral triangle.

Answer:

The 2 triangles on the right and left are isosceles, so they have 2 equal sides. Consequently, the angles at the base are equal.

Because the opposite angles of a vertix are equal, the triangle in the lower part has the angles x, 58° and 47°.

Because the sum of the inner angles of a triangle is 180, x= 180- (58+47)

x= 180-105 = 75°

Answer: x = 72

Step-by-step explanation:

The triangle with ∠a is an isosceles triangle; the other two angles are congruent, let them be y

a + y + y = 180 (sum of angles in triangles)

58 + 2y = 180

Subtract 58 from both sides

2y = 122

Divide both sides by 2

y = 61°

In the triangle with ∠b, b is congruent to another angle, (isosceles triangle) let it be b.

b = 47°

y and b have a relationship with the other two of the angles with ∠x (vertical angles); let them be y and b.

y + b + x = 180

61 + 47 + x = 180

108 + x = 180

Subtract both sides by 108

x = 72

Answer:

130

Step-by-step explanation:

when adding you positive number to a negative number you have to subtract. so to make it easier im going to change it from -240 +370 to

370-240 and solve

370-240=130

Step-by-step explanation:

Answer:

x=5.9

Step-by-step explanation:

First, you want to isolate x so you have to subtract 31.7 from both sides. This will make the equation -3x=-17.7. Because they are both sides are negative, you can change both sides to positive so it will be 3x=17.7. Next, you want x to be 1 so you have to divide 3 in both sides. This will make the equation x=17.7/3. Simplify that to get x=5.9.

Answer:

396π.cm^3

Step-by-step explanation:

ere's your solution

=> height of cylinder = 11 cm

=> radius of cylinder = 6 cm

=> volume = πr^2h

=> putting the value of radius and height in formula

=>volume = 6^2*11 π

=> volume = 36*11 π

=> Volume = 396π .cm^3

Answer:

A general exponential equation is written as:

y = a*(b)^x

Where:

y represents the amount of something as a function of the variable x, where x is an independent variable.

a is the initial amount, this is, the value of y when x = 0.

b is the rate of growth, this defines how much changes the value of y as x increases.

Answer:

y - 9 = 1/8(x - 1)

Step-by-step explanation:

Answer:

Ken class has a median of 84 while Judy class a median of 87

Step-by-step explanation:

Ken class has a median of 84 while Judy class a median of 87

Kens class has a mean score of 83, and Judy's class has a mean score of 86.43(rounded) so, judging by the mean, Judy's class is smarter. If we take a look at the median, (Ken: 84, and Judy: 87) then Judy's class is smarter. So, overall Judy's class is smarter than Ken's class.

Answer:

Height = 8 units

Step-by-step explanation:

Area of a triangle = [tex]36\frac{4}{5}[/tex] square units

                             = [tex]\frac{184}{5}[/tex] square units

Height of the triangle = [tex]9\frac{1}{5}[/tex] units

                                    = [tex]\frac{46}{5}[/tex] units

Formula to calculate the area of a triangle is,

Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

[tex]\frac{184}{5}= \frac{1}{2}\times (\frac{46}{5})\times (\text{Height})[/tex]

[tex]\frac{184}{5}= (\frac{46}{10})\times (\text{Height})[/tex]

Height = [tex]\frac{184}{5}\times \frac{10}{46}[/tex]

           = [tex]\frac{368}{46}[/tex]

           = 8 units

Therefore, height of the given triangle is 8 units.

Answer:

A

Step-by-step explanation:

Simply guess and check, meaning the boys category must be divisible by 2 and the girls category must be divisible by 3

A: 24 boys ÷ 2 = 12 (equals a whole number so it is divisible; not a decimal)

36 girls ÷ 3 = 12 (both of the boys and girls are divisible by their corresponding numbers)

Yes

Now make sure the boys are a lower count than the girls as the ratio says it should be 2 to 3, meaning there are more girls than boys

B: 20 ÷ 2 = 10 (divisible)

35 ÷ 3 = 11.666 (this is a decimal answer so it is not divisible)

No

C: 36 ÷ 2 = 18

24 ÷ 3 = 8

Yes, they are divisible

Now lets check if boys have a lower count than girls

36 boys > 24 girls

This is not the solution as it doesn't reflect the correct ratio of less boys than girls

D: 35 ÷ 2 = 17.5 (not divisible)

20 ÷ 3 = 6.66 (not divisible)
