Answer:

The number of paving stones she needs is 540 paving stone

Step-by-step explanation:

The given dimensions of Pisces' inground pool = 10 m by 5 m

The thickness of the border surrounding the pool = 1 1/2

The dimensions of each paving stone = 25 cm by 40 cm = 0.25 m by 0.4 m

The length dimension of the pool and border = 10 + 2 × 1 1/2 = 13 m

The width dimension of the pool = 5 + 2 × 1 1/2 = 8 m

The total area of the paving stone, [tex]T_A[/tex] = Area of pool + border - Area of pool

∴ [tex]T_A[/tex] = 13 m × 8 m - 10 m × 5 m = 54 m²

The total area of the paving stone = 54 m²

The area of each paving stone, [tex]A_{EP}[/tex] = 0.25 m × 0.4 m = 0.1 m²/paving stone

The number of paving stones she needs, n = (The total area of the paving stone)/(The area of each paving stone)

∴ n = 54 m²/(0.1 m²/paving stone) = 540 paving stone.

Answer:

35.34 and 16.66

Step-by-step explanation:

Given data

let the numbers be x and y

the smaller number = x

the larger number = y

x+y=52--------1

The larger number is 2 less than twice the smaller number

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

put y= 2x-2 in eqn 1

x+2x-2=52

3x-2=52

3x=52-2

3x=50

x= 50/3

x= 16.66

put x=16.66 in eqn 1 to find y

x+y=52

16.66+y= 52

y=52-16.66

y= 35.34

Hence the numbers are

35.34 and 16.66

Check

35.34+16.66= 52

Answer:

zero, because the discriminant is negative

Step-by-step explanation:

By writing the quadratic formula, we have the discriminant written in the root as;

b^2-4ac

Now, given the expression, we can see that the discriminant here is -19

What this mean is that we have a negative discriminant

Hence, we can conclude that the roots are complex and as such, none of the roots are real

Answer:

12

Step-by-step explanation:

just divide 96 by 8

Answer:

y=12

Step-by-step explanation:

.......ur welcome.........

96÷8=12

bcs they're 8 y we divide 96 by the no. of y to get y

Answer:

7.24 + 5.3 = 3m

=> 3m = 12.54

=> m = 12.54/3

=> m = 4.18

506 x - 92 y + 90 = 498 - 4 x + 6 y

Geometric figure:

line

y = (255 x)/49 - 204/49

510 x - 98 y - 408 = 0

506 x - 92 y + 90 = 6 (y + 83) - 4 x

Real solution:

y = (255 x)/49 - 204/49

Solution:

y = (255 x)/49 - 204/49

Integer solution:

x = 49 n + 40, y = 255 n + 204, n element Z

Solution for the variable y:

y = 51/49 (5 x - 4)

Answer:

Hi! The answer to your question is [tex]x =\frac{49y}{255} +\frac{4}{5}[/tex]

Ben score -60

Sam score -20

Step-by-step explanation:

let Sam score be X

let Ben score be 3x

X+3x =80

4x =80

X=80/4

X =20 ........Sam score

Ben score=3x

=3 ×20

=60

Answer: A is 5 B is 6 C is 3

D is 7

Step-by-step explanation: I hope u get ur answer- and if I’m wrong plz tell me I took this lesson 2 days ago-

Answer:

Option:D

According to question,

Mass = m/3

Volume = 5*v

Density = mass/volume

=1/15*(m/v)

So its option D

Answer:

Can you attach the figure?

Step-by-step explanation:

Answer:

1st ans

(x+15)=135(alternate angle)

x=135-15

x=120

2nd ans

(8x-4)=92(corresponding angle)

8x=92+4

x=96/8

x=12

3rd ans

(x+1)=51(vertically opposite angle)

x=51-1

x=50

Answer:

Divide 9 from both sides

Step-by-step explanation:

9x = 45

[tex]\frac{9x}{9} = \frac{45}{9}[/tex][tex]x = 5[/tex]

Answer:

4 and 3 are coefficanta and 12 will be a constant.

if 4 and 3 are being shared by the variable they would be coefficants

if x is not a variable then all the numbers are constants

Answer:

2.2 inches

Step-by-step explanation:

smallest dimension = (smallest ratio / total ratio) x volume

(smallest ratio = 1

total ratio = 1 + 1.5 + 4.2 = 6.7

(1/6.7) x 14.49 = 2.2 inches

Answer:

k = -2

Step-by-step explanation:

firstly, let us examine the kind of transformation that we have

We have a transformation from (3,2) to (3,0) and (-3,0) to (-3,-2)

So, we are actually subtracting 2 from the values of f(x) to get the values of g(x)

This shows a vertical translation to the tune of 2 units in the downward direction

So, the correct answer here is that -2 is being subtracted from f(x) to give g(x)

Accordingly, the value of k in the question is -2

Answer:

b

Step-by-step explanation:

Answer:

Options B and E.

Step-by-step explanation:

We want to see for which systems the point (-3, 2) is a solution (a solution of a system means that both equations intersect in that point).

The point (-3, 2) is a solution of the system only if this point belongs to both linear equations in the system.

Then for each system, we need to replace x by -3 and y by 2 in both equations and see if the equality is true or not.

A)

6x - y = 15

-3x + 4y = -18

In the first equation we have:

6*(-3) - (2) = 15

-18 - 2 = 15

-20 = 15

This is false, so we can discard option A.

B)

2x + y = -4

3x + 2y = -5

In the first equation we have:

2*(-3) + 2 = -4

-6 + 2 = -4

-4 = - 4  

This is true, now let's look at the other equation.

3*(-3) + 2*(2) = -5

-9 + 4 = -5

-5 = - 5

This is also true, then the point (-3, 2) is a solution for both equations, then the point (-3, 2) is a solution for the system.

C)

x + 8y = 19

4x - 5y = 2

In the first equation we have:

(-3) + 8*(2) = 19

-3 + 16 = 19

13 = 19

This is false, then we can discard option C.

D)

8x + y = 22

-2x - 5y=4

In the first option we have:

8*(-3) + 2 = 22

-24 + 2 = 22

-22 = 22

This is false, so we can discard option D.

E)

5x - y = -17

x + 4y = 5

In the first option we have:

5*(-3) - (2) = -17

-15 - 2 = -17

-17 = -17

This is true, now let's look at the other equation:

(-3) + 4*(2) = 5

-3 + 8 = 5

5 = 5

This is also true, then the point (-3, 2) is a solution for both equations in the system, which means that the point (-3, 2) is a solution for the system.

Then the correct options are B and E.
