Answer:

Step-by-step explanation:

In an isosceles triangle, by definition two of the three sides of the triangle are equal to one another. Therefore, the angles opposite to these sides must also be equal. And considering the Triangle Sum Theorem, the angles of a triangle must add up to 180 degrees, the angle that measures 124 degrees cannot be be equal to another angle due to the fact that the sum of them would exceed 180. Therefore let x be the angle:

124+2x=180

2x=56x=28

Answer:

$5.10 For the 2 extra panes

Step-by-step explanation:

So 9 pained are 22.95

22.95/9=2.55

Since 2 panes are broken

2.55*2

that is 5.1

or $5.10

Answer:

$5.20

Step-by-step explanation:

First, we need to work out how much 1 pane is.

So $22.95÷9=$2.55

Then you times it by 2

So $2.55×2=$5.20

Answer:

y=32x shows a proportional relationship.

Step-by-step explanation:

We need to find an equation that shows the proportional relationship.

If x and y are proportional to each other, it will look like,

y = mx

Where

m is constant of proportionality

Out of 4 option, option (4) is y=32x, it shows the proportional relationship where the value of m is equal to 32.

The equation that represents a proportional relationship is y = 32x

A proportional relationship usually has the form:

y = kx

Where:

In this equation: y = 32x

Step-by-step explanation:

If we select any random point on Figure S, let's just say the upper right hand corner of the arrow at (2,3), and compare that to the same point but on Figure T, it is now (4,6). By just looking at the two points, we can see that the x and y values of the point we chose from Figure S had to be doubled to get to that point but in Figure T

Given:

Sum of the radius of the base and height of a cylinder = 21 cm

Curved surface area of the cylinder = 616 sq.cm

To find:

The total surface area of the cylinder.

Solution:

Let r be the radius of the base and h be the height of the cylinder.

Sum of the radius of the base and height of a cylinder = 21 cm

[tex]r+h=21[/tex]

[tex]h=21-r[/tex]           ...(i)

Curved surface area of the cylinder is

[tex]CSA=2\pi rh[/tex]

Curved surface area of the cylinder = 616 sq.cm

[tex]2\pi rh=616[/tex]

[tex]2(\dfrac{22}{7})r(21-r)=616[/tex]

[tex]44r(21-r)=616\times 7[/tex]

[tex]21r-r^2=\dfrac{616\times 7}{44}[/tex]

[tex]21r-r^2=14\times 7[/tex]

[tex]0=98-21r+r^2[/tex]

[tex]0=98-14r-7r+r^2[/tex]

[tex]0=14(7-r)-r(7-r)[/tex]

[tex]0=(7-r)(14-r)[/tex]

[tex]r=7,14[/tex]

Using (i), for r=7, h=14 and for r=14, h=7.

Total surface area of the cylinder is

[tex]A=2\pi r(r+h)[/tex]

For r=7 and h=14,

[tex]A=2(\dfrac{22}{7})(7)(7+14)[/tex]

[tex]A=44(21)[/tex]

[tex]A=924[/tex]

For r=14 and h=7,

[tex]A=2(\dfrac{22}{7})(14)(14+7)[/tex]

[tex]A=88(21)[/tex]

[tex]A=1848[/tex]

Therefore, the total surface area of the cylinder is either 924 sq.cm or 1848 sq. cm.

Answer:

[tex]Adults = 510[/tex]

Step-by-step explanation:

Given

[tex]Children = \frac{3}{5}[/tex]

[tex]Girls:Boys = 2 : 7[/tex]

[tex]Girls = 170[/tex]

Required

Determine the number of adults

First, we need to calculate the number of children

[tex]Girls:Boys = 2 : 7[/tex]

Given that: [tex]Girls = 170[/tex]

Substitute 170 for Girls in [tex]Girls:Boys = 2 : 7[/tex]

[tex]170 : Boys = 2 : 7[/tex]

Convert to fraction

[tex]\frac{170}{Boys} = \frac{2}{7}[/tex]

Cross Multiply

[tex]Boys * 2 = 170 * 7[/tex]

Divide both sides by 2

[tex]Boys = \frac{170 * 7}{2}[/tex]

[tex]Boys = \frac{1190}{2}[/tex]

[tex]Boys = 595[/tex]

So, the number of children are:

[tex]Children = Boys + Girls[/tex]

[tex]Children = 595 + 170[/tex]

[tex]Children = 765[/tex]

Next, we calculate the number of people in the cinema.

[tex]Children = \frac{3}{5} * People[/tex]

Substitute 765 for Children

[tex]765 = \frac{3}{5} * People[/tex]

Make People the subject.

[tex]People = \frac{765 * 5}{3}[/tex]

[tex]People = \frac{3825}{3}[/tex]

[tex]People = 1275[/tex]

If 3/5 are children, then 2/5 are adults.

So:

[tex]Adults = \frac{2}{5} * 1275[/tex]

[tex]Adults = \frac{2* 1275}{5}[/tex]

[tex]Adults = \frac{2550}{5}[/tex]

[tex]Adults = 510[/tex]

Answer:

x = -1/5, x = i sqrt(30)/5,  x = -i sqrt(30)/5

Step-by-step explanation:

25x^3 + 5x^2 + 30x + 6 = 0

5x^2(5x + 1) + 6(5x + 1) = 0

(5x + 1)(5x^2 + 6) = 0

5x + 1 = 0

5x = -1

x = -1/5

5x^2 + 6 = 0

5x^2 = -6

x^2 = -6/5

x = +/- sqrt(-6/5)

x = +/- i * sqrt(30)/5

x = i sqrt(30)/5 or x = -i sqrt(30)/5

Answer:

Perimeter of triangle = 12 + 9 + 15

                                   = 36 units

Therefore, option A is correct.

Step-by-step explanation:

The given points

From the table, it is clear the side containing the line segment joining the points (-4, 5) and (8, 5) is a straight horizontal line.

Thus, the length of the horizontal distance from the points (-4, 5) and (8, 5) will be:

8-(-4) = 12 units

From the table, it is clear the side containing the line segment joining the points (8, 5) and (8, -4) is a straight vertical line.

Thus, the length of the vertical distance from the points (8, -4) and (8, 5) will be:

5-(-4) = 9

Now, finding the length of the side containing the segment (8, -4) and (-4, 5) using the formula:

[tex]\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

[tex]=\sqrt{\left(-4-8\right)^2+\left(5-\left(-4\right)\right)^2}[/tex]

[tex]=\sqrt{\left(-4-8\right)^2+\left(5+4\right)^2}[/tex]

[tex]=\sqrt{12^2+9^2}[/tex]

[tex]=\sqrt{144+81}[/tex]

[tex]=\sqrt{225}[/tex]

[tex]=\sqrt{15^2}[/tex]

[tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a[/tex]

[tex]=15[/tex]

We know that the Perimeter of a rectangle is the length of all the sides of the triangle. Therefore, combining all the lengths of the line segments

Thus,

Perimeter of triangle = 12 + 9 + 15

                                   = 36 units

Therefore, option A is correct.

Answer:

[tex]y=\frac{1}{2} x-8[/tex]

Step-by-step explanation:

Slope-intercept form is organized in the form y=mx+b, where m is the slope and b is the y-intercept.

Because we're already given the values, we just have to plug them into the equation.

[tex]y=mx+b\\y=\frac{1}{2} x+(-8)\\y=\frac{1}{2} x-8[/tex]

To graph this equation, first plot a point at (0, -8). This is because the y-intercept is -8, meaning that the line crosses the y-axis when y=-8.

Then, plot the next point using the slope. The slope is equal to the rise/run of the line, or the number of units the line travels upwards / the number of units the line travels to the right. Because the slope is 1/2, we know that for every 2 units a point travels to the right, it goes up by 1 unit.
