Answer:

x = 2/3 and y = 8/9

Step-by-step explanation:

If a parallelogram INDY has diagonals that intersects at P, then O bisects ID and YN

Hence IP = PD and NP = YP

Given

IP=3x

DP = 6x - 2

NP = 3y and

YP=7x-2,

Substitute

3x = 6x-2

3x-6x = -2

-3x = -2

x = 2/3

x = 0.67

Also NP = YP

3y = 7x-2

3y = 7(2/3) - 2

3y = 14/3 - 2

3y = 14-6/3

3y = 8/3

9y = 8

y = 8/9

Hence x = 2/3 and y = 8/9

The circumference when the area of a circle is 16π ft² is 8π feet.

The area of a shape simply means the total space that is taken by the shape. It simply expresses the extent of the region on a particular plane as well as a curved surface.

From the information given the area of a circle is 16π ft² be we want to calculate the circumference, in feet. This will be Illustrated this:

Circumference of a circle = 2πr

Area of a circle = πr²

r = radius.

Therefore, based on the information regarding the area given, the radius will have to be calculated first.

Area = 16π

πr² = 16π

r² = 16π / π

r² = 16

r =✓16

r = 4

Radius = 4ft.

Therefore, the circumference will be:

= 2πr

= 2 × π × 4

= 8π

Circumference is 8π feet.

Answer:

18

Step-by-step explanation:

18 US tons are equal to 36,000 pounds

Answer: 12 books

Step-by-step explanation:

First you need to remove the cost of shipping from the total amount:

= 75 - 3

= $72

The above is the total amount spent on the books without shipping.

If each book cost $6, the total number of books bought is:

= 72 / 6

= 12 books

The value of x from the given diagram using the similarity theorem of a triangle is 7

In order to get the value of x from the given triangle, we will use the similarity theorem of a triangle.

From the given triangle, the following equation is true;

5/40 = 3/2x + 10

Cross mutiply

5(2x + 10) = 3(40)

10x + 50 = 120

10x = 120 - 50

10x = 70

x = 7

Hence the value of x from the given diagram is 7

Step-by-step explanation:

Answer: W=25 and L=50

Step-by-step explanation: I first started out with 50, because 50 is half of 100. 50 divided by 2 equals twenty five. Now, I moved on to 100. 100 divided by 2 equals 50. 25+25+50+50=150.

Answer:

The width of the basketball court is 25 feet and the length is 50 feet

Step-by-step explanation:

Equations:

Let's make:

x = width of the basketball court

2x = length of the basketball court

The perimeter of the court is twice the width plus twice the length:

P = 2x + 2(2x)

P = 2x + 4x = 6x

It's known to be 150 feet, thus:

6x = 150

Dividing by 6:

x = 150/6

x = 25 feet

2x = 50 feet

The width of the basketball court is 25 feet and the length is 50 feet

Answer:

The graphs do intersect at two values of x;

x = 1

and

x = -1

Step-by-step explanation:

We have the two equations:

y = 2*x - 9

y = -(x - 1)^2 - 7

We know that when we graph these equations, the graphs do intersect.

if the graphs intersect, then we must have at least one point (x, y) that is a solution for both equations.

because in this point y is the same for both equations, then we can write:

2*x - 9 = y = -(x - 1)^2 - 7

this leads to the equation:

2*x - 9 = -(x - 1)^2 - 7

now we can solve this for x.

2*x - 9 + (x - 1)^2 + 7 = 0

2*x + x^2 - 2*x + 1 + 7 - 9 = 0

x^2 - 1 = 0

x^2 = 1

x = √1

Then we have two possible solutions:

x = 1, and x = -1

Step-by-step explanation:

step 1. let's call the line in the middle y.

step 2. y = sqrt(5^2 + 7^2) = sqrt(74). pythagorean theorem.

step 3. x^2 + y^2 =100 (pythagorean theorem))

step 4. x^2 + (sqrt(74))^2 = 100.

step 5. x^2 = 100 - 74

step 6. x^2 = 26

step 7. x = sqrt(26). note: sqrt is the square root.

The value of the x is [tex]\sqrt{26}[/tex].

To understand more, check below explanation.

Apply Pythagoras theorem in right side triangle,

            Hypotenuse[tex]=\sqrt{5^{2}+7^{2} } =\sqrt{25+49}=\sqrt{74}[/tex]

Now apply Pythagoras theorem in the left side triangle,

              [tex]Hypotenus^{2} +x^{2} =10^{2} \\\\(\sqrt{74} )^{2} +x^{2} =100\\\\x^{2} =100-74=26\\\\x=\sqrt{26}[/tex]

Hence, the value of the x is [tex]\sqrt{26}[/tex].

Answer:

Each cheerleader needs to raise 38.14 more

Step-by-step explanation:

Answer:

They each need to raise $38.14.

Step-by-step explanation:

For this problem, I started off by subtracting 317.30 from 622.42.

(622.42-317.30) This gave us 305.12.

I did this, because we are trying to find the amount of money the cheerleaders have left to make.

Next, we will divide the difference of this equation (305.12) by 8.

We did this because there are 8 cheerleaders, and they all made the same amount of money.

This leaves us with an answer of:

Each cheerleader has exactly $38.14 left to make.

The tangent of a angle is opposite side/ adjacent side

In a rights triangle with a 45° angle we have a special 45-45-90 triangle.

The legs of the triangle are congruent and are the opposite and adjacent sides of the 45° angle.  Therefore, the ratio of those two sides is 1.

Therefore, the tangent of 45° = 1
