2. What is the slope of the line below?

Answer:

the diameter of the base is 15cm. Find the curved surface area of cone. Solution: Given that, Slant height: l = 20cm

Slant = root of 30^2 + 40^2 = 50

Curved surface area = pi *r*l

pi*15*50

= 750*pi = 750*3.14

= 2355 cm ^2

Answer:

D

Step-by-step explanation:

frequency is the students and most of them (10) study 5-6 hours ♡

Concluimos que a partir de 21 piezas se gana más en la empresa B.

Si definimos el número de piezas vendidas como x, la cantidad que le pagan en la empresa A es:

A(x) = $6000 + $20*x

Y lo que le pagan en la empresa B es:

B(x) = $6000 + x^2

Queremos ver para que valor de x, se da que B(x) > A(x).

Entoces resolvamos esa inequación.

6000 + 20*x < 6000 + x^2

20x < x^2

20 < x

x debe ser más grande que 20, entonces concluimos que a partir de 21 piezas se gana más en la empresa B.

Answer:

The correct answer would be C. The coordinates of the ENDPOINTS of the segment​

Step-by-step explanation:

It cannot be A, because the segment only moves. It does not change size.

It cannot be B, because the line of symmetry goes down the middle of the segment- the distance remains the same.

Therefore it is C. The coordinates of the ENDPOINTS of the segment​

Answer:

[ ] = 3¹³

Step-by-step explanation:

3¹⁷ - 3¹⁵ + 3¹³ = [ ] x 73

3¹³ [3⁴ - 3² + 1] = [ ] x 73

3¹³ [81 - 9 + 1] = [ ] x 73

3¹³ x 73 = [ ] x 73

[ ] = 3¹³ [It says 3^13 if it is not clear/visible]

Answer:

33.5%

Step-by-step explanation:

First you need to subtract the amount he bought the ticket from the amount he sold it.

$121 ₋ $88

=$33

After that you need to divide the answer you got by the original amount of the ticket multiply it  by 100.

33 ÷ 88 × 100

=37.5%

Step-by-step explanation:

Answer:

  No Solution

Step-by-step explanation:

You can use the expression for y provided by the first equation to substitute for y in the second equation.

  y = x +1

  x -(x +1) = 1

  -1 = 1

There are no values of the variables x and y that will make this equation true. The system has No Solution.

__

Additional comment

Solving the second equation for y gives ...

  y = x -1

This graphs as a line parallel to the line representing the first equation. A system describing parallel lines has no solution, because the lines never meet, and the solution is the point where they meet.

Answer:

no possible answer.

Step-by-step explanation:

1. y = x+1

2. x-y = 1

3. x = 1+y

Substitute equation 3 into the x in equation 1:

y = (1+y)+1

y = 2+y

y-y = 2

0=2

"0 = 2" isn't valid, thus there is no possible answer to this question.

Step-by-step explanation:

Option A is the answer because the line after letter B should be 2.5, and were talking about the one between 2 and 2.5. Which means that, Option A should be your correct answer.

Answer: 9x + 3y = 12

Alternative forms: y = 0.4 OR y = [tex]2/3^{2}[/tex]

Step-by-step explanation:

2x + y = 2         subtract 2x from both sides

2x - 2x + y = 2 - 2x

y = -2x + 2

(m = -2, b = 2)

-3x + y = 4        add 3x to both sides

-3x + 3x + y = 4 + 3x

y = 3x + 4

(m = 3, b = 4)

Hey there!

10x+y=7(x+y)=7x+7y

or 10x−7x=7y−y

or 3x=6y

or x=2y ........(1)

Number formed by reversing the digits is yx, i.e.,

10y+x=10x+y−18

Substituting x=2y, we get

10y+2y=10×2y+y18

or 2y=21y−18

or 21y−12y=18

or 9y=18

or y=2

∴x=2y=2×2=4

Therefore, the number is 42.

Let the two digit number be ' xy '

where, x is the ten's place digit, and y is one's place digit, now let's proceed further ~

The origin number can be written as :

[tex]\qquad \sf  \dashrightarrow \: 10x + y[/tex]

[ because x is at ten's place ]

of the digits are swapped, the new number will be :

[tex]\qquad \sf  \dashrightarrow \: 10y + x[/tex]

According to conditions provided in the question : -

[tex]\qquad \sf  \dashrightarrow \: 10x + y = 7 \times (x + y)[/tex]

[tex]\qquad \sf  \dashrightarrow \: 10x + y = 7x + 7y[/tex]

[tex]\qquad \sf  \dashrightarrow \: 10x - 7x + y - 7y= 0[/tex]

[tex]\qquad \sf  \dashrightarrow \: 3x - 6y = 0 \: \: \: \: \: \: [/tex]

[tex]\qquad \sf  \dashrightarrow \: x - 2y = 0 \: \: \: \: \: \: - (1)[/tex]

here we got our first equation, let's find the other one ~

[tex]\qquad \sf  \dashrightarrow \: (10x + y) - 18= 10y + x[/tex]

[tex]\qquad \sf  \dashrightarrow \: 10x - x + y - 10y = 18[/tex]

[tex]\qquad \sf  \dashrightarrow \: 9x - 9y = 18[/tex]

[tex]\qquad \sf  \dashrightarrow \: x - y = 2 \: \: \: \: \: \: - (2)[/tex]

we got our second equation ~

Now it's time to subtract equation (1) from equation (2) :

[tex]\qquad \sf  \dashrightarrow \:( x - y ) - (x - 2y)= 2 - 0[/tex]

[tex]\qquad \sf  \dashrightarrow \: \cancel{x }- y - \cancel{x} + 2y= 2 - 0[/tex]

[tex]\qquad \sf  \dashrightarrow \: y= 2 [/tex]

hence, value of y is 2, use this value in equation (2) to find x ~

[tex]\qquad \sf  \dashrightarrow \: x - y= 2 [/tex]

[tex]\qquad \sf  \dashrightarrow \: x - 2= 2 [/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 4 [/tex]

Therefore, the required number is xy = 42

Answer:

104/1000

Step-by-step explanation:

If she tries two each week you will need to know how many weeks are in a year.Now about 52 weeks are in a year so you would multiply 52 by 2 and get 104.

Here, we need to find the fraction of recipes she would have tried in the book after 1 year

The fraction of recipes she would have tried in the book after 1 year is 13/125

Total recipes in the book

[tex] = \frac{Total recipe she tried in a year}{Total recipes in the book } [/tex]

= 1,000

Recipe tried each week = 2

Find the fraction of recipe she would have tried after 1 year

There are 52 weeks in 1 year

she tried 2 recipes each week

Total recipe she tried in a year

=

[tex] = total \: number \: of \: weeks \: in \: a \: year \: \times number \: of \: recipe \: tried \: per \: week[/tex]

[tex] = 52 \times 2[/tex]

[tex] = 104[/tex]

fraction of recipe she would have tried after 1 year

[tex] = \frac{Total recipe she tried in a year}{Total recipes in the book } [/tex]

= [tex] \frac{104}{1000} [/tex]

Divide by 8

= 13/125
