Answer:

The system of equations 3x + 7y = 80 and 6x + 3y = 63.75 can be used to determine the cost of one CD and one DVD.

Step-by-step explanation:

Given that:

Cost of 3 CDs and 7 DVDs = $80

Cost of 6 CDs and 3 DVDs = $63.75

Let,

x be the cost of one CD

y be the cost of one DVD

According to given statement;

3x + 7y = 80

6x + 3y = 63.75

Hence,

The system of equations 3x + 7y = 80 and 6x + 3y = 63.75 can be used to determine the cost of one CD and one DVD.

Answer:

d=25

Step-by-step explanation:

d=C/Pi

d=25pi/pi

d=25

Answer:

Diameter = 25

Step-by-step explanation:

The circumference of a circle is 25 pi

Circumference of a circle is given by,

C = 2πr

25π = 2πr

Dividing both sides by 2π

[tex]\frac{25\pi}{2\pi}=\frac{2\pi r}{2\pi}\\\\12.5 = r\\[/tex]

Diameter = 2r

Diameter = 2(12.5)

Diameter = 25

The volume of cylinder and cone are [tex]36\pi[/tex] cubic unit.

It is given by formula, [tex]V=\pi r^{2}h[/tex]

Where r is base radius and h is height of cylinder.

Given that,  [tex]r=3,h=4[/tex]

Substitute values in above formula,

         [tex]V=\pi*3^{2} *4=36\pi[/tex]

Volume of the cone is,

                 [tex]V=\frac{1}{3} \pi r^{2}h[/tex]

Given that, [tex]r=3,h=3*4=12[/tex]

Substitute values in above formula.

Step-by-step explanation:

1.5x + 3 = -2x + 3    -1.5x = -2x   0.5x = 0  x = 0

Which is 0,3 and it’s only one solution.

The equation that gives the solution together with y = -1.5x + 3 is

y = -2x + 3

Option E is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 - 9 is an equation.

We have,

y = -1.5x + 3 ____(1)

y = -2x + 3 ____(2)

From (1 ) and (2) we get,

-2x + 3 = -1.5x + 3

-2x + 1.5x = 3 - 3

-0.5x = 0

x = 0

Now,

y = -2x + 3

y = 0 + 3

y = 3

Thus,

The solution is (0, 3).

Answer:

b. 63

Step-by-step explanation:

A Parallelogram is known to be a flat shape quadrilateral which has four opposite sides Each two opposite sides are parallel and are equal in length. The opposite angles are equal.

The above answer is correct because opposite angles of a parallelogram are equal:

m∠CDA = m∠ABC

where m∠CDA = 63

Step-by-step explanation:

CDB and CEA are similar=>CD/CE=DB/EA=>5/9=DB/18=>

9DB=90

DB=10

The required length of DB in the diagram below is 10 cm.

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

Given:

In the given triangle we have

СD=5 cm

DE= 4 cm

EA= 18 cm

According to given question we have

In a triangle CDB and CEA are similar

So,

[tex]\frac{CD}{CE} =\frac{DB}{EA}\\\\=\frac{5}{9} =\frac{DB}{18}\\\\=9DB=90\\\\DB=10[/tex]

Answer:

YZ = 12

Step-by-step explanation:

From the question given above, the following data were obtained:

Length of XZ = 13

Lenght of XY = 5

Lenght of YZ =?

The length of YZ can be obtained by using pythagoras theory since the figure is a right angle triangle. This can be obtained as follow:

XZ² = XY² + YZ²

13² = 5² + YZ²

169 = 25 + YZ²

Collect like terms

169 – 25 = YZ²

144 = YZ²

Take the square root of both side.

YZ = √144

YZ = 12

Therefore, the length of YZ is 12

Answer:

580 seedlings altogether.

Step-by-step explanation:

Given that,

Ali plants 40% of the total number of seedlings, Ben plants 45% of the total number of seedlings, and Cliff plants the rest of the seedlings. Cliff plants 87 seedlings.

The percentage of the seedling planted by Cliff = 100% - 45% - 40% = 15%

Let x = the total number of seedlings

[tex]15\%\ of\ x=87\\\\x=\dfrac{87\times 100}{15}\\\\x=580[/tex]

Hence, three boys plant 580 seedlings altogether.

Answer: 18 feet

Step-by-step explanation:

Well, first we need to find the circumference because that is the outside of the pipe.

Circumference = 2 x Pi x Radius

Radius is half of diameter.

So we plug in all the values in to the formula.

2 x Pi x 6 inches = Circumference

12Pi = 37.69911184 inches

37 inches to feet = about 3 feet.

3 x 6 = 18 feet.

Answer:

x = 11

Step-by-step explanation:

3(x-5) = 18

Step one: Distrubute 3 to the numbers in the parenthesis.

3x - 15 = 18

Step two: Add 15 on both sides

3x = 33

Step three: Divide by 3 on both sides

x = 11

Answer:

Its the second option

Step-by-step explanation:

Answer:

x=2.5

Step-by-step explanation:

1/2(6x-10)-x=0 Replace the ? with a 0 so you can solve for x.

So your going to want to distribute everything in parentheses by 1/2 first to get 3x-10-x=0 Next your going to simply the equation by combining like terms to get 2x-5=0. Next add five to both sides so that 2x=5. Finally divide both sides by 2 and the answer is x=2.5.
