They ate 3/6 of the pizza, or simplified as 1/2.

Don't have enough time to explain it, but they ate 3/6 or 1/2 all together.

Graphing the line with a slope -1 passing through the point (2,-1)

4vir4ik [10]

Answer:

y=-x+1

Step-by-step explanation:

The slope is -1. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.

(y--1)=-1(x-2)

y+1=-x+2

y=-x+1

12. Venu and Tanuj are running along a circular track. They take 48 seconds and 56 seconds to

brilliants [131]

Answer:

The meet at first time at starting point after 336 seconds,

Vanu have completed 7 laps while Tanuj has completed 6 laps.

Step-by-step explanation:

Given that Venu and Tanuj take 48 seconds and 56 seconds to

complete a lap respectively.

To meet them again at the startiong point, the time taken must be multiple of 56 and 48.

So, the minimum time required to meet them again at the startiong point is time taken for first time meet.

Time taken to first time meet is the smallest number which can be divided by 56 and 48, i.e the lowest common factor (LCM) of 56 and 48 which is 336 seconds or 5 minutes 36 seconds.

Number of laps by Venu

$=\frac{336}{48}=7$

Number of laps by Tanuj

$=\frac{336}{56}=6$

How do you find x and y from this diagram? I have no clue...

Montano1993 [528]

50 + (3x - y) = x + (2x - 16). Combine like terms to change the 2nd part to get 3x - 16. 50 + 3x-y = 3x - 16. Subtract 3x from both sides to get 50 - y = -16. Subtract 50 from both sides to get -y = - 66, or y = 66. 90 - 50 = 40 = 3x - 66. Add 66 to both sides to get 3x = 106, or x = 35 1/3.

PLEASE HELP!!! Would you rather paint 3/4 of a circle or a circular ring? Using area, explain your reasoning. Include calculatio

Nostrana [21]

Answer: I would paint either of the 3/4 of a circle or a circular ring.

Step-by-step explanation: We shall start by calling the three quarter circle on the left A, and the ring on the right we shall call B.

The area of both can be calculated and that figure which results in the lesser value (of area) shall cost you less to paint.

For A, the area of the circle is given as

Area = πr²

Where π shall be taken as 3.14 and the radius r is 6.

Area = 3.14 * 6²

Area = 3.14 * 36

Area = 113.04

The area of the quarter of the circle would be subtracted from the total area as shown in the calculation above.

Area of sector = ∅/360 * πr²

The sector is a quarter of the circle and that makes the angle at the sector to be equal to (360/4) 90 degrees. Therefore ∅ equals 90.

Area of sector = (90/360) * 113.04

Area of sector = 1/4 * 113.04

Area of sector = 28.26

Area of A therefore is derived as;

Area of A = 113.04 - 28.26

Area of A = 84.78 square metres

For B, the area of the ring is given as follows;

Area of B = Area of larger circle - Area of smaller circle

Area of B = πR² - πr²

Where R is the radius of the larger circle and r is the radius of the smaller inner circle. By factorizing the right hand side of the equation, we now have;

Area of B = π (R² - r²)

Area of B = 3.14 (6² - 3²)

Area of B = 3.14 (36 - 9)

Area of B = 3.14 * 27

Area of B = 84.78 square metres.

From the calculations shown along with the explanations, both the three-quarters and the ring have exactly the same area, which means you are going to spend exactly the same quantity of paint and spend the same amount of time painting either one of them.

So the answer is; I would paint EITHER ONE OF THEM.
