Answer:9

Step-by-step explanation:

6/4 = x/6

4x=36

4x/4 36/4

x=9

The length of the segment DC will be 9 units.

A two dimensional shape made up of the three sides and making an angle of 180 degrees is called as triangle.

Given that:-

The length of DC will be calculated by using the ratios:-

6/4 = x/6

4x=36

4x/4 36/4

x=9

Therefore the length of the segment DC will be 9 units.

Answer:

The computer will be worth $1,850 after four years.

Step-by-step explanation:

We need to find 6.5% of $2,500.

2,500 x 0.065 = $162.50

Therefore, the computer value decreases by $162.50 each year. Since we need to know the computer value after 4 years, we also need to multiply the value of decrease by 4.

162.5 x 4 = $650

Therefore, after 4 years, the computer value will decrease by $650.

To find the whole computer value after 4 years, we need to subtract the initial value of $2,500 by the 4-year decreasing value of $650.

2,500 - 650 = $1850

Therefore, the computer will be worth $1,850 after four years.

Hope this helps! :D

Explanation:

Sort the values from smallest to largest: {2, 5, 6, 10, 10}

Now cross off the first and last values to get this smaller set: {5, 6, 10}

Repeat the process one more time and we get this: {6}

This shows 6 is the middle most item of the original sorted set above. Therefore, 6 is the median.

let

brenda: b

will: 3b

b + 3b = 240

4b = 240

b = 60 lbs (BRENDA)

3b = will

3 (60) = will

180 = WILL

The solution is

The weight of Brenda = 60 pounds

The weight of Will = 180 pounds

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the weight of Brenda be = x

Let the weight of Will be = y

Now , Will weighs three times as much as Brenda

Substituting the values in the equation , we get

y = 3x   be equation (1)

And , the weight of Will + weight of Brenda = 240 pounds

So , x + y = 240   be equation (2)

Substituting the value of y from equation (1) in equation (2) , we get

x + 3x = 240

On simplifying the equation , we get

4x = 240

Divide by 4 on both sides of the equation , we get

x = 60 pounds

So , the weight of Brenda is 60 pounds

Substitute the value of x in equation (1) , we get

y = 3x

y = 3 x 60

y = 180 pounds

So , the weight of Will is 180 pounds

Hence , the weight of Brenda is 60 pounds and weight of Will is 180 pounds

Answer:

It will take 5 minutes to pump 100 gallons of oil

Answer:

the Diameter of second circle is 50

Step-by-step explanation:

Area of first circle = 25 π

Diameter of first circle = d

Diameter of second circle= 5(Diameter of first circle) (because Another circle has a diameter 5 times the first)

We need to find diameter of 2nd circle.

First we find diameter of first circle.

The formula for area of circle is: [tex]Area=\pi r^2[/tex]

We also know that: [tex]Diameter = 2r[/tex]

First we will find radius and using diameter formula we can find diameter of the circle.

[tex]Area=\pi r^2\\25\pi =\pi r^2\\r^2=\frac{25\pi}{\pi}\\r^2=25\\Taking\:square\:root\:on\:both\:sides\\\sqrt{r^2}=\sqrt{25}\\r=5[/tex]

So, radius of first circle is r = 5

Now, finding diameter of first circle:

[tex]Diameter = 2r\\Diameter= 2(5)\\Diameter= 10[/tex]

So, Diameter of first circle = 10

Now, we know that diameter of second circle is 5 times the first

So, Diameter of second circle = 5(Diameter of first circle)

Diameter of second circle = 5(10)

Diameter of second circle = 50

So, the Diameter of second circle is 50

Answer:

b = -12

Step-by-step explanation:

First isolate b by subtracting 2 from both sides: b/4 = -3

then multiply both sides by 4 to find b: b = -12

Answer:

b= -12

Step-by-step explanation:

b/4 + 2 = -1

Subtract 2 from both sides

b/4 = -3

Multiply both sides by 4

b= -12

It's an inverse operation thing.

Answer: See explanation

Step-by-step explanation:

From the question, we are told to prove that prove d + (8d + 1) + 7 is equivalent to 8 + 9d.

= d + (8d + 1) + 7

First we need to open the bracket. This will be:

= d + (8d + 1) + 7

= d + 8d + 1 + 7

Collect like terms

= 9d + 8

= 8 + 9d

Therefore, we have proven that + (8d + 1) + 7 is equivalent to 8 + 9d.

Answer:

The length of YZ is 22.30mm.

Step-by-step explanation:

Basically we need to find the hypotenuse of the triangle, or the longest side.

The formula for finding the hypotenuse of a triangle is: c = √(a² + b²)

First we need to multiply 14.3 and 17.1 to the second power.

14.30 × 14.30 = 204.49

17.10 × 17.10 = 292.41

Now we add our two sums.

204.49 + 292.41 = 496.90

Now we need to find the square root of 496.90, which is 22.2912539.

Rounded to the nearest DP(Decimal point), it's 22.30

Answer:

The greatest number of flowers that could be in a bouquet is 9 flowers.

Each bouquet would contain: 3 roses, 1 daise and 5 tulips

Step-by-step explanation:

Sandy has 27 roses, 9 daisies, and 45 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?

We solve the above question using Greatest Common Factor method.

We find the factors of 27, 9 and 45

The greatest common factor is the highest factor common to these 3 number

Hence:

The factors of 9 are: 1, 3, 9

The factors of 27 are: 1, 3, 9, 27

The factors of 45 are: 1, 3, 5, 9, 15, 45

Then the greatest common factor is 9.

Therefore, the greatest number of flowers that could be in a bouquet is 9 flowers

Each bouquet would contain

For 27 roses = 27/9 bouquet = 3 roses

For 9 daisies = 9 daisies/9 bouquet = 1 daisies

For 45 tulips = 45 tulips/9 bouquet = 5 tulips
