i am very sure

Answer:

Rs.3210

Step-by-step explanation:

CP=Rs.3000

Sp=x

Tax %=7/100x3000=Rs.210

SP=3000+210

=Rs.3210

Answer:

Rs 3210

Step-by-step explanation:

7/100 x 3000 = 210

3000 + 210 = 3210

Answer:

x = 61

Step-by-step explanation:

A straight line equals 180, so:

2x + 3 + x - 6 = 180

add like terms

3x - 3 = 180

add 3 to both sides

3x = 183

divide by 3

x = 61

Answer:

x = 25, y = 9

Step-by-step explanation:

Since the triangles are congruent then corresponding angles and sides are congruent, thus

∠ O = ∠ P , substitute values

6y - 14 = 40 ( add 14 to both sides )

6y = 54 ( divide both sides by 6 )

y = 9

and

NG = IT , that is

x - 2y = 7 ( substitute y = 9 into the equation )

x - 2(9) = 7

x - 18 = 7 ( add 18 to both sides )

x = 25

Answer: 8x-5y+30=0

Step-by-step explanation:

in slope intercet form y= 8/5x + 6≈1.6x + 6

Answer:

what spinner?

Step-by-step explanation:

Answer:

5/12, 4 1/4, 4 2/3

Step-by-step explanation:

Change your fractions so they all have a common denominator.

A common denominator is 12, so 5/12 stays as is, 4 1/4 changes to 4 3/12,

and 4 2/3 changes to 4 8/12.

So,      5/12 = 5/12

      4 1/4.     = 4 3/12

       4 2/3     = 4 8/12

Answer:

Larry is incorrect

Step-by-step explanation:

A composite number is a number that is divisible by itself, 1, and any other number. He is incorrect. For example, the number 23 isn't composite, even though there is a 2 in the ones place. The number 23 is ONLY divisible by 23 and 1 -- not any other number.

Hope this helped :)

Answer:Larry is correct

Step-by-step explanation:

Larry is correct because if u were to write a list of how many prime numbers are between 1 and 100 u would get 2,3,5,7,11,13,17 and so and so u would not get a number that ends with a two and be prime.

Answer:

30 Girls

Step-by-step explanation:

[tex]\frac{10}{15}[/tex] = [tex]\frac{20}{x}[/tex]

Using cross multiplication you get 20 * 15 / 10 which equals 30.

Answer:

28 units

Step-by-step explanation:

Since, given triangles have same perimeters.

[tex] \therefore \: 5x + 5x + 3x + 2 = 6x + 3 + 2x + 1 + 4x \\ \\ 13x + 2 = 12x + 4 \\ \\ 13x - 12x = 4 - 2 \\ \\ x = 2 \\ \\ \implies 12x + 2 = 12( 2) + 4 = 24 + 4 = 28 \: units \\ \\ \&\: 13x + 2 =13(2) + 2 = 26 + 2 = 28 \: units\\ \\ [/tex]

So perimeter of each triangle is 28 units

Answer:

D. -(-2/9)

Step-by-step explanation:

Once you distribute the negative sign, it makes the same answer.

-2 times -1 = 2

9 times -1 = -9

Answer:

7.35582 * 10^17 %

110.68122%

Step-by-step explanation:

Inflation rate per month = 2000%

The inflation rate per year will be:

Using the relation :

Final amount = initial amount(1 + rate)^t

Here monthly rate = 2000% = 2000 / 100 = 20

Final amount = initial amount(1 + 20)^t

Final amount = initial amount(21)^12

Hence, the inflation rate after 12 months = 1year will be :

21^12 = 7355827511386641

(7355827511386641 * 100)%

= 7.35582 * 10^17 %

Daily inflation rate :

Number of days in a month = 30

Hence,

(1 + 20)^(1/30)

21^0.0333333 = 1.1068122

(1.1068122 * 100)% = 110.68122%

Answer:

-23

Step-by-step explanation:

Substitute -5 for n to get 4(-5)-3 = -20-3 = -23

Answer:

5

Step-by-step explanation:

Answer:

no

Step-by-step explanation:

Answer:

No, the graph does not represent a proportional relationship. It is a straight line, but it does not intersect the point (0, 0). ... It's not proportional because the line does not cross through the origin. Therefore the ratio of x to y will be different for two different points on the line.

Answer:

The answer is D

Step-by-step explanation:

if you use the equation 3x=x+18 and subtract x from the side you get 2x=18 and therefore x=9

and if you put x in for the variables you get 27 for both sides and there are 2 sides so you get 108 for the perimeter

Answer:

40 ft squared

Step-by-step explanation:

To calculate area of a rectangle, you use the formula length times width, or base times height.

5 x 8 = 40 feet squared

Answer:

296 miles

Step-by-step explanation:

4 hours=240 minutes

240/30=8

37*8=296

Answer:

Joe travels 296 miles in 4 hours.

Step-by-step explanation:

How many minutes in an hour? 60.

How many minutes in 4 hours then? 60 * 4 = 240 minutes

Now take 240 minutes and divide it by 30. You get 8, this is what you need to multiply 37 by.

37 * 8 = 296.

Therefore, Joe travels 296 miles in 4 hours.
