Find the value of x.

Answer:

4 units

Step-by-step explanation:

A triangle has vertices on the coordinate grid at points D (3, -3), E (0, 2), and F (-1, -3). What is the length, in units, of DF ?

A triangle is a polygon with three sides and three angles.

The distance between two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] on the coordinate plane is given by:

[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Given A triangle with vertices at points D (3, -3), E (0, 2), and F (-1, -3). The length of side DF is given as:

[tex]DF=\sqrt{(-1-3)^2+(-3-(-3))^2}=4\ units[/tex]

Answer: 1 inch = 9 yards

Step-by-step explanation:

From the question, we are informed that Rita drew a scale drawing of a picnic area near the river and that the picnic area, which is 135 yards long in real life, is 15 inches long in the drawing.

From the above, we can see that for every 1 inch, there are (135/15) = 9 yards. Therefore, the scale used Is:

1 inch = 9 yards

Answer:

20.0 units

Step-by-step explanation:

[tex]\boxed{distance = \sqrt{ {(y1 - y2)}^{2} + {(x1 - x2)}^{2} }}[/tex]

Distance between (5, 9) and (-7, -7)

[tex] = \sqrt{( - 7 - 9)^{2} + ( - 7 - 5)^{2} } [/tex]

[tex] = \sqrt{( - 16)^{2} + ( - 12)^{2} } [/tex]

[tex] = \sqrt{256 + 144} [/tex]

[tex] = \sqrt{400} [/tex]

Answer:

he's at work for 9 hours 55minutes

Carlos works for 8 hours and 55 minutes.

Given that, Carlos starts work at 21:20 and finishes at 06:15 the next day.

A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year.

The 24-hour clock is more often shown on digital clocks and is written in a 4-digit form, with the first two digits representing the hour and the last two representing the minutes.

From 21:20 to 06:15 there are 8 hours and 55 minutes.

Therefore, Carlos works for 8 hours and 55 minutes.

Answer:

6abc

Step-by-step explanation:

In this equation, one is given both variables and constant. One can only combine like terms; variables of the same parameter with other variables of the same parameter, or constant with constants. In this situation, three different variables are given, but two constants are given. One can combine the constant, but one must leave the variables as they are. Thus:

3 * b * 2 * ac

= 3 * 2 * b * ac

= 6abc

Answer:

Step-by-step explanation:

Answer:  ONLY 15, and 24 there are not more 2 digit triply numbers i have checked all the 2 digits numbers ranging from 10 to 99

Yes there are only 2 triply numbers! Isnt it shocking! I have tried for 2 digit triply numbers from 10 to 99! Yes i did that! Lets go through a basic idea first the product of its digits mean that you mulitply whatever number your checking for a triply number. Example: your checking 15 for a triply number so 1 x 5 = 5 ( you multiply the digits in the 2 digit number to find the product of its digit)! What does 3 times the product of its digits then? hmmmmm. we know that 15's product of its digit is 5 so we mulitiply 5 x 3 because it says three times the product of its digits.

Step-by-step explanation:

15 = 1 x 5 = 5 (we do 1 x 5 because we need to find the product of its digits and to do that we multiply the digits together in the 2 digit number).

5 x 3 = 15 (we multiplied 15 x 3 because it says 3 times the product of its digits. we know the product is 5 and 3 times is multiply by 3 so we do 5 x 3 which equals to 15).

So 15 is a triply number because in the second step when we multiplied 5 x 3 we got 15; and we were checking if 15 was a triply number; because we got 15 as the answer in the second step it is a triply number).

24 = 2 x 4 = 8

8 x 3 = 24  

so we got 24 as the answer again in the second step which means that 24 is a triply number.

In short, you multiply the digits in the number then whatever you get as the answer you multiply it by 3. if you get the digits from te number that you multiplied then you know that number is a triply number. from the number 10 to 99 there are ONLY 2 NUMBERS. I saw people only give 2 numbers online and i was like why does no one give all the triply but in reality there are only 2 triply numbers which are 2 digits. You can check for yourself if you dont believe me using the method above. Thank you! I hope it helped if it helped please give me a thumbs up!

We will find that the "triply" numbers are:

-15, 15, -24, 24.

We know that these aer two-digit numbers, so we can write them as:

a*10 + b

Where a and b are single-digit numbers.

A "triply" number is equal to 3 times the product of its digits, then we must have:

a*10 + b = 3*(a*b)

Moving all to one side, we have:

10a + b + 3ab = 0

So a "triply" number must meet the above criteria.

Now, the values that can take b are all the single-digit values {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

So now we need to evaluate b and find the possible vales of a.

if b = 0, then:

10*a + 0 - 3*a*0 = 0

10*a = 0

Then a = 0, but this will not give a 2-digit number.

if b = 1 then:

10*a + 1 - 3*a*1 = 0

10*a - 3a = -1

7*a = -1

a = -1/7

This is not a single-digit number.

if b = 2

10*a + 2 - 3*2*a = 0

4*a = -2

a = -2/4

This is not a single-digit number.

if b = 3

10*a + 3 - 3*3*a = 0

a = -3

a should be positive.

if b = 4 we have:

10a + 4 - 12a = 0

-2a = -4

a = -4/-2 = 2

So this gives the number 24.

if b = 5 we have

10a + 5 - 15a = 0

-5a = -5

a = -5/-5 = 1

So this gives the number 15

if b = 6

10a + 6 - 18a = 0

-8a = -6

a = -6/-8

This is not a single-digit.

if b = 7

10a + 7 -21a = 0

-11a = -7

a = -7/-11

At this point we can see that for larger values of a, we will not get more tripply numbers.

So the only "triply" numbers are: 15 and 24 (and their opposites, -15 and -24).

Answer:

8.7 feets

Step-by-step explanation:

As obtained frommthe diagram attached :

Base, b of triangle = 6 feets

Height of triangle, h = 12 feets

Volume of a Triangular Prism is obtained using the relation :

Base Area * Width

Base area of prism :

0.5 * base * height

0.5 * 6 * 12 = 36ft²

Width, w of the ramp =x

Volume, V = 313.2 ft³

V = base area * width

313.2 = 36 * x

313.2 = 36x

x = 313.2 / 36

x = 8.7 feets
