Answer:

1) 199

2) 899

Step-by-step explanation:

1)

The 2-digit number is the number formed from unit-digit and ten-digit

∵ The greatest digit is 9

→ To form the greatest 2-digit number use 9 as ten-digit and unit-digit

∴ The greatest 2-digit number is 99

The 3-digit number is the number formed from unit-digit, ten-digit, and hundred-digit

∵ The smallest digit is 0

→ To form the smallest 3-digit number use 0 as ten-digit and unit-digit,

   we can not use 0 for the hundred-digit so use 1 as hundred-digit  

∴ The smallest 3-digit number is 100

∵ The sum of them = 99 + 100

∴ Their sum is 199

2)

→ To form the greatest 3-digit number use 9 as hundred-digit, ten-digit,

   and unit-digit

∴ The greatest 3-digit number is 999

∵ The smallest 3-digit number is 100

∵ The difference between them = 999 - 100

∴ The difference between them = 899

Answer:

Yes, These numbers 10, 7, and 13 can form a triangle

Step-by-step explanation:

Let us use this theorem to solve the question

∵ The numbers are 10, 7, 13

∵ 10 + 7 = 17

∵ 17 > 13

∴ The sum of 10 and 7 is greater than the 3rd number 13

∵ 10 + 13 = 23

∵ 23 > 7

∴ The sum of 10 and 13 is greater than the 3rd number 7

∵ 7 + 13 = 20

∵ 20 > 10

∴ The sum of 7 and 13 is greater than the 3rd number 10

∵ The sum of every two numbers is greater than the 3rd number

→ By using the theorem above

∴ The numbers 10, 7, and 13 can form a triangle

Answer:

b. AD II DC

math is annoying, a lot of the stuff they teach we don't use in the real world lol

Answer:

If anything, AB DC seems like it would be right because AD BC doesnt line up with angles real well. Im not entirely sure; educated guessing.

Answer:

A tourist receives 2376 ec currency in exchange for us 1200.

Step-by-step explanation:

This can be calculated as follows:

Tax rate = 1%

Amount of us currency = 1200

Total amount of ec currency = Amount of us currency * 2 = 1200 * 2 = 2400

Amount of tax = Total amount of ec currency * Tax rate = 2400 * 1% = 24

Net amount of ec currency = Total amount of ec currency - Amount of tax = 2400 - 24 = 2376

Net amount ec currency obtained above is the amount of ec currency which a tourist receives in exchange for us 1200.

Therefore, a tourist receives 2376 ec currency in exchange for us 1200.

Answer:

12/11

Step-by-step explanation:

6/11 / 3/6

Simplify

6/11 / 1/2

Preform division, remember, dividing a number by a fraction is the same as multiplying that number by the reciprocal of that fraction

6/11 * 2/1

12/11

Answer:

The value of x = 5

Step-by-step explanation:

Length of the pool = 20 feet

Width of the pool = (20 minus x) feet

Area of the pool = 300 square feet

Area of a rectangular pool = length × width

300 = 20 (20 - x)

300 = 400 - 20x

Subtract 400 from both sides

300 - 400 = 400 - 20x - 400

- 100 = - 20x

Divide both sides by -20

x = -100/-20

= 5

x = 5

The value of x = 5

Answer:

x=12

Step-by-step explanation:

(2x-4)/5=4

We move all terms to the left:

(2x-4)/5-(4)=0

We multiply all the terms by the denominator

(2x-4)-4*5=0

We add all the numbers together, and all the variables

(2x-4)-20=0

We get rid of parentheses

2x-4-20=0

We add all the numbers together, and all the variables

2x-24=0

We move all terms containing x to the left, all other terms to the right

2x=24

x=24/2

x=12

Answer:

x = 12

Step-by-step explanation:

Given

[tex]\frac{2x-4}{5}[/tex] = 4 ( multiply both sides by 5 to clear the fraction )

2x - 4 = 20 ( add 4 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Answer:

The answer is in the explaination

Step-by-step explanation:

A + B = 180 degrees

14x - 72 = 180

14x = 108

x = 8

A = 5 times 8 plus 20

A = 60

Answer:

110 degrees.

Step-by-step explanation:

Angle A + Angle B = 180 degrees.

Therefore, 5x+20+9x-92=180

When you solve you get 14x=252 or x=18

When you plug that into A you get 5(18)+20=110

Therefore, A=110 degrees

Solving [tex]6^2-(1.1+7.4)+1.5[/tex] we get [tex]\mathbf{29}[/tex]

Step-by-step explanation:

We need to solve:

[tex]6^2-(1.1+7.4)+1.5[/tex]

First solving brackets

[tex]=6^2-(8.5)+1.5\\=6^2-8.5+1.5\\[/tex]

Now solving 6^2

[tex]=36-8.5+1.5\\[/tex]

Now subtracting 8.5 from 36

[tex]=27.5+1.5[/tex]

Now adding the above values

[tex]=29[/tex]

So, solving [tex]6^2-(1.1+7.4)+1.5[/tex] we get [tex]\mathbf{29}[/tex]

no
