There are 15 plates in a kitchen cabinet. The diameter of each plate is either 7in or 12in. The diameter of all 15 plates combined is 140in. Which system of equations can be used to find the number of 7in plates, x , and the number of 12in plates, y , that are in the cabinet?

Answers

Answer 1

Answer:

Number of 7 inch plate = 8

Number of 12 inch plate = 7

Step-by-step explanation:

There are 15 plates in a kitchen cabinet. The diameter of each plate is either 7in or 12in. The diameter of all 15 plates combined is 140in. Which system of equations can be used to find the number of 7in plates, x , and the number of 12in plates, y , that are in the cabinet?

Given that :

Total Number of plates = 15

Diameter of each plate : 7 in or 12 in

Diameter of all 15 plates = 140 in

Let number of 7 in and 12 in diameter plates = x and y respectively ;

x + y = 15 - - (1)

7x + 12y = 140 - - - (2)

x = 15 - y

Substitute x = 15 - y in (2)

7(15 - y) + 12y = 140

105 - 7y + 12y = 140

105 + 5y = 140

5y = 140 - 105

5y = 35

y = 7

From x = 15 - y

x = 15 - 7

x = 8

Number of 7 inch plate = 8

Number of 12 inch plate = 7

HURRY PLEASE!!! Which generic rectangle would be used to factor x^2+7x+6

Answers

Answer:

Rectangle B

Step-by-step explanation:

Given the expression x^2+7x+6, to get the required rectangle we need to factorize first;

= x^2+7x+6

= x^2+6x+x+6

= x(x+6)  + 1 (x+6)

= (x+1)(x+6)

From line 2 we will see that the terms contains x², 6x, x and 6. The rectangle that contains all this terms is rectangle B. Hence option B is correct.

f the line with equation y=−2x+7 is rotated 90° clockwise about the origin, what are the coordinates of the image of its y-intercept?

A. (2,0)
B. (7,0)
C. (0,−7)
D. (−7,0)

Answers

Answer:

B

Step-by-step explanation:

I looked it up

The line with equation y=−2x+7 is rotated 90° clockwise about the origin, the coordinates of the image of its y-intercept is D  (−7,0).

What is y-intercept of a function?

The intersection of the graph of the function with the y-axis gives y-intercept of that function.

The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x)

At y-axis, we've got x = 0, so putting it will give us the y-intercept.

Thus, y-intercept of y = f(x) is y = f(0)

To find the y-intercept of the line y=-2x+7. When x=0 we have that y=-2·0+7, y=7,

then point (0,7) is the y-intercept.

When we rotate this line 90° clockwise about the origin, then point (0,7) will be placed on the x-axis in positive x-direction.

Rotation preserves the distances, then the coordinates of the image are (7,0).

The correct choice is D  (−7,0).

Solve the following equation to determine the value of x:
3x + (x + 10) + 5x + (2x + 2) = 56

Answers

Answer:

4

Step-by-step explanation:

since it's all addition, we can remove the parentheses

[tex]3x + x + 10 + 5x + 2x + 2 = 56[/tex]

Now we combine like terms

[tex]3x+x+5x+2x+10+2=56[/tex]

[tex]11x+12=56[/tex]

We subtract both sides by 12 to get,

[tex]11x=44[/tex]

now we divide both sides by 11

[tex]x=\frac{44}{11}[/tex]

[tex]x=4[/tex]

A cylindrical water vessel of diameter 1.4 m holds 770 litres of water. find the height of the vassel​

Answers

Answer:

Answer at the bottom!!

Step-by-step explanation:

Given the diameter of cylinder = 1.4 m

=> Radius = 1.4/2 = 0.7 m

We know that volume of a cylinder = πr²h

= 3.14 x 0.7² x 2.1= 3.23 m³

For the pipe radius = 3.5/2 = 1.75 cm = 0.0175m

water flows at a rate of 2 m per second

So, volume of water discharged in one second by pipe = πr²L

= 3.14 x 0.0175² x 2=0.0019

Hence time taken by the pipe to fill the cylinder

= 3.23/0.0019= 1700 sec

= 28 minutes and 20 seconds

Hence the time taken by the pipe to fill the cylinder is 28 minutes and 20 seconds.

Hope this helps!!
