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

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

Here is 16 divided by 1/4 displayed mathematically in colors:

16

 ÷    

1

4

The numbers in 16 divided by 1/4 are labeled below:

16 = whole number

1 = numerator

4 = denominator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

16 x 4

1

 =    

64

1

Thus, the answer to 16 divided by 1/4 in fraction form is:

64

1

To make the answer to 16 divided by 1/4 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

64 / 1 = 64

The answer is rounded to the nearest two decimal points if necessary.

64/1 is an improper fraction and should be written as 64.

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.

Answer:

The area will be:

[tex]A=18(1+\sqrt{3}) \: u^{2}[/tex] or [tex]A=49.18 \: u^{2}[/tex].

Step-by-step explanation:

Using the definition of tangent, we have:

[tex]tan(\alpha)=\frac{6}{\vec{AB}}[/tex]

We know that tan(α) = 1, then we can find AB

[tex]1=\frac{6}{\vec{AB}}[/tex]

[tex]\bar{AB}=6\: u[/tex]

u means any unit.

Now, we need to find the distance BC. If the angle ∠D is 60°, then ∠C must be 30°. Using the tangent definition in the triangle BCD we have:

[tex]tan(30)=\frac{6}{\bar{BC}}[/tex]

[tex]\bar{BC}=\frac{6}{tan(30)}[/tex]

[tex]\bar{BC}=\frac{6}{1/\sqrt{3}}[/tex]

[tex]\bar{BC}=6\sqrt{3} \: u[/tex]

So, the base of the triangle will be:

[tex]b=\bar{AB}+\bar{BC}=6+6\sqrt{3}=6(1+\sqrt{3}) \: u[/tex]

The area of a triangle is given by the following equation:

[tex]A=\frac{b*h}{2}[/tex]

[tex]A=\frac{6(1+\sqrt{3})*6}{2}[/tex]

[tex]A=18(1+\sqrt{3})[/tex]

Therefore, the area will be [tex]A=49.18 \: u^{2}[/tex].

Answer:

2

Step-by-step explanation:

2 is the only factor that goes into 6 and 16. (6th's Factors) 1, 2, 3 and 6

(16th Factors) 1, 2, 4, 8 and 16.

The greatest common factor of 6 and 16 is 2.

To find the greatest common factor (GCF) of 6 and 16, we need to determine the largest number that can divide both 6 and 16 without leaving a remainder.

First, we find the factors of each number:

Factors of 6: 1, 2, 3, 6

Factors of 16: 1, 2, 4, 8, 16

By comparing the factors, we can identify that both 6 and 16 have a common factor of 2. However, 6 also has a factor of 3, which is not a factor of 16.

To determine the GCF, we select the highest common factor, which is 2.

Therefore, the greatest common factor of 6 and 16 is 2.

The GCF is an essential concept in mathematics as it helps simplify fractions, factorize expressions, and solve various mathematical problems. It allows us to identify the largest number that can evenly divide two or more given numbers.

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.

Step-by-step explanation:

Answer: See explanation

Step-by-step explanation:

a. Let the money in m savings account be represented by x.

If I doubled the money in my savings account, I would have $150.62. This means that:

(2 × x) = $150.62

2x = $150.62

Divide both side by x

2x/2 = $150.62/2

x = $75.31

The amount in the savings account is $75.31

b. Let the hourly wage be represented by x.

Three times the hourly wage plus $7.65 in tips equals $27.90. This will be:

(3 × x) + 7.65 = 27.90

3x + 7.65 = 27.90

3x = 27.90 - 7.65

3x = 20.25

x = 20.25/3

x = 6.75

The hourly wage is $6.75
