Answer:

Step-by-step explanation:

Solve this by adding the volume of the cylinder with the volume of the cone.  The volume of a cylinder is found from the equation:

pi * r^2 * h

In this case that gives pi * 50^2 * 30 = 75000pi

The area of the cone is found from the equation:

pi * r^2 * h *1/3

In this case you get pi * 50^2 * 10 * 1/3=  8333.pi

Add the two to ger 83333.333*pi ~261799

The two angles are supplementary angles, which when added together equal 180 degrees.

6x -10 + 6x +10 = 180

Combine like terms:

12x = 180

Divide both sides by 12:

x = 180/12

x = 15

The answer is C) 15

Answer:

Given:

The system of equation is:

[tex]-2x+4y=16[/tex]

[tex]2x+2y=8[/tex]

To find:

The solution of the given system of equations.

Solution:

We have,

[tex]-2x+4y=16[/tex]              ...(i)

[tex]2x+2y=8[/tex]                ...(ii)

Add (i) and (ii) to eliminate the variable x.

[tex]6y=24[/tex]

[tex]y=\dfrac{24}{6}[/tex]

[tex]y=4[/tex]

Putting [tex]y=4[/tex] in (ii), we get

[tex]2x+2(4)=8[/tex]

[tex]2x+8=8[/tex]

[tex]2x=8-8[/tex]

[tex]2x=0[/tex]

Divide both sides by 2.

[tex]x=0[/tex]

Therefore, the solution of given system of equations is (0,4). Hence, the correct option is A.

Step-by-step explanation:

Divide numerator by denominator

[tex]\frac{10}{4}[/tex] = 2.5 ← not a whole number

[tex]\frac{8}{4}[/tex] = 2 ← a whole number

[tex]\frac{3}{6}[/tex] = 0.5 ← not a whole number

Answer:

x = 51

Step-by-step explanation:

Supplementary angles total 180º

(2x + 4) + (x + 23) = 180

Combine like terms

3x + 27 = 180

Subtract 27 from both sides

3x = 153

Divide both sides by 3

x = 51

Answer:

Hello! x = 51

Step-by-step explanation:

OMG I CAN ANSWER FINALLY!

it is forming a supplementary angle meaning it will add up to 180 degrees

51 × 2 = 102 102 + 4 = 106

51 + 23 = 74

106 + 74 = 180 therefore x = 51 Hope that helps.

Given:

Triangle EFG is congruent to triangle YXZ by ASA.

To find:

The other corresponding parts can be marked congruent by CPCTC.

Solution:

We have,

[tex]\Delta EFG\cong \Delta YXZ[/tex]

We know that the corresponding parts of congruent triangles are congregant (CPCTC). So,

[tex]\angle E\cong \angle Y[/tex]

[tex]\angle F\cong \angle X[/tex]

[tex]\angle G\cong \angle Z[/tex]

[tex]EF\cong YX[/tex], it is also written as [tex]FE\cong XY[/tex]

[tex]FG\cong XZ[/tex], it is also written as [tex]GF\cong ZX[/tex]

[tex]EG\cong YZ[/tex], it is also written as [tex]GE\cong ZY[/tex]

Therefore, the correct options are 2, 6 and 7.

Answer:

The total money which is collected is $72..

Answer:

c

Step-by-step explanation:

Answer:

No. The correct solution is (3,-1)

Step-by-step explanation:

Since we are using elimination method, we can go ahead and see that we can cancel "-y" from the first equation and "+y" from the second equation.

Once  we do that, we go ahead add the like terms and get 3x = 9

Then, we divide by 3 on each side and get  x = 3

Now, we can take that value of x and plugin to any of the original 2 equations we started with.

Say we plugin x = 3 into the second equation.. it will turn to, 2(3) + y = 5

Then we solve for y.

2(3) + y = 5

6 + y = 5

6 - 1 = 5

y = -1

There, we found our x value and our y value, (3,-1)  :)

Explanation:

List out the perfect squares

and so on. We can see that 46 is between 6^2 = 36 and 7^2 = 49.

We can say 6^2 < 46 < 7^2

Applying the square root to all three sides leads us to 6 < sqrt(46) < 7

Now multiply all three sides by -1. This will flip the inequality signs

We go from

6 < sqrt(46) < 7

to

-6 > -sqrt(46) > -7

It might help to order things from smallest to largest to get this

-7 < -sqrt(46) < -6

This means -sqrt(46) is between -7 and -6 on the number line

See the diagram below.

Answer:

Step-by-step explanation:

First notice that -√46 lies between -√49 and -√36, that is, between

                                                              -7   and  -6.  

Here all three numbers are negative because they lie to the left of zero (0) on the number line.

Answer:2.3

Step-by-step explanation:

Cut the the shape into a right triangle and a rectangle

Tri: find measure of the base

sin(45)= opp/hyp

          = x/1.8

        1.8 *sin (45)  = x

x = 1.3

base of tri = 1.3

Area of tri = 1/2bh

                     1/2(1.3)(1.3)

                    =0.845

Area of rectangle: 1.1*1.3=1.43

Total area = 1.43+0.845

                  =2.245

                  =2.3m^2

The length of the longer piece is 124/7.

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.

let the two pieces be x(longer) and y (shorter)

So,

x+y=31

and, 3x=4y

3x-4y=0

Solving both the equations:

x= 124/7 and y=93/7

Hence, the length of longer piece is 124/7.

Answer:

Step-by-step explanation:

The angle (angle D) created by 2 tangents to a circle (DC and DA) is half of the difference between its intercepted arcs (arc ABC - arc AC):

[tex]65=\frac{1}{2}(x-[360-x])[/tex] If we don't know the measures of either of the arcs, but we DO know that the measure around the outside of a circle is 360 degrees, then we will call arc ABC "x", making arc AC "360 - x". Solving:

2(65) = 2x - 360 and

130 = 2x - 360 and

130 + 360 = 2x and

490 = 2x so

x = 245. This means that arc ABC is 245 and arc AC is 115.

Answer:

3 years

Step-by-step explanation:

Let y = number of orangutans, and let x = number of years.

For each study, the population, y, after x years is:

First study:

y = 784 - 25x

Second study:

y = 817 - 36x

We set the populations equal and solve for x, the number of years.

784 - 25x = 817 - 36x

Add 36x to both sides. Subtract 784 from both sides.

11x = 33

Divide both sides by 11.

x = 3
