Answers
Answer:
y=(5/3)x
Step-by-step explanation:
Since y varies directly with x, then the constant of proportionality is equal to k=y/x. Since y/x=20/12=5/3, then k=5/3. This means the equation to relate x and y is y=(5/3)x

Step-by-step explanation:
50.4/2 = 25.2. 61.92/2 = 30.96
Answer:
56.16 m²
Step-by-step explanation:
→ Work out the area of the middle rectangle
7.2 × 7.6 = 54.72 m²
→ Work out the area of the triangle on the left side
0.5 × 7 × 7.2 = 25.2 m²
→ Work out the area of the triangle on the right side
0.5 × 8.6 × 7.2 = 30.96 m²
→ As it asks for the shaded area, add up the triangle area
30.96 + 25.2 = 56.16 m²
A parabola has its focus at (1,2) and its directrix is y = −2. The equation of this parabola could be...?
Answers
9514 1404 393
Answer:
y =1/8(x -1)^2
Step-by-step explanation:
The vertex is halfway between the focus and directrix, so has y-coordinate (2-2)/2 = 0. The x-coordinate of the vertex is the same as that of the focus. The focus-vertex distance (p) is 2-0 = 2. Where the vertex is (h, k), the equation is ...
y = 1/(4p)(x -h)^2 +k
For p=2, (h, k) = (1, 0), the equation of the parabola is ...
y = 1/8(x -1)^2

2 burgers for $5.76 or 1 burger for $3.52 witch is better? prove your answer.
Answers
Answer:
2 burgers for $5.76
Step-by-step explanation:
We can do a ratio
1 : 3.52
2 : 5.76
1 : 3.52
2 : ?
Multiply 3.52 by 2 since thats what has been done from 1 to 2.
3.52 * 2 = 7.04
New
1 : 3.52
2 : 7.04
From the original one....
1 : 3.52
2 : 5.76
2 : 576 > 2 : 7.04
The one that is better is 2 burgers for 5.76, because per burger it will cost 2.88 and it will cost less than the original one....

Answer:
12 + 2.75h ≠ 30
Or
31.26 ≠ 30
Step-by-step explanation:
12 + 2.75h = 30
We want to single out the variable so subtract 12 from both sides.
12 + 2.75h = 30
-12 -12
Now we can move down the number and then divide.
12 + 2.75h = 30
-12 -12
2.75h = 18
h ≠ 6.54545454(A repeating number.)
Since this is a repeating number we’ll take the whole number and multiply it by 2.75. Then we’ll add the 12 and compare.
2.75 x 6 = 16.5 + 12 = 28.5 < 30
28.5 is less than 30 so this is true correct answer. See what happens when you add another 2.75.
28.5 + 2.75 = 31.25 > 30
The question says *at most* meaning it’s can be equal to or less than 30. 31.25 is great than 30 so it cannot be this number.
There’s your answer.
Either 12 + 2.75 ≠ 30 or 31.25 ≠ 30

In the “Lucky Chances” lottery a box has 100 balls. 60 balls are marked “Good.” 40 balls are marked, “Bad.” To play this lottery, you draw a ball at random and look at the message. You play this lottery every day. What happens over the course of 500 plays?
Answers
Answer:
Lucky Chances” lottery a box has 100 balls. 60 balls are marked “Good.” 40 balls are marked, “Bad.” To play this lottery, you draw a ball at random and look
Over the course of 500 plays, you can expect to draw a "Good" ball 300 times.
Over the course of 500 plays, you can expect to draw a "Bad" ball 200 times.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The probability of drawing a "Good" ball is 60/100 or 0.6.
The probability of drawing a "Bad" ball is 40/100 or 0.4.
We can use these probabilities to determine what will happen over the course of 500 plays:
On average, you can expect to draw a "Good" ball 0.6 times for every play. So over the course of 500 plays, you can expect to draw a "Good" ball 0.6 x 500 = 300 times.
On average, you can expect to draw a "Bad" ball 0.4 times for every play. So over the course of 500 plays, you can expect to draw a "Bad" ball 0.4 x 500 = 200 times.
Note that these are expected values based on the probabilities, and there is no guarantee that you will actually draw exactly 300 "Good" balls and 200 "Bad" balls.
However, over a large number of plays, the actual results should approach these expected values.
Thus,
Over the course of 500 plays, you can expect to draw a "Good" ball 0.6 x 500 = 300 times.
Over the course of 500 plays, you can expect to draw a "Bad" ball 0.4 x 500 = 200 times.

An element with a mass 310 grams decays by 5.7% per minute. How much of the element is remaining after 9 minutes, to the nearest 10th of a gram
Answers
Mass of an element = 310 grams
Percentage of the element that will decay in a minute = 5.7%
Quantity of the element that will decay in one minute :
[tex] = \frac{5.7 \times 310}{100} [/tex]
[tex] = \frac{1767}{100} [/tex]
[tex] = \tt17.67 \: grams[/tex]
Thus, 17.67 grams of the element will decay every minute.
Quantity of element that will decay after nine minutes :
[tex] = 17.67 \times 9[/tex]
[tex] =\tt 159.03 \: grams[/tex]
Thus, 159.03 grams of the element will decay after 9 minutes.
Quantity of element that will remain after 9 minutes :
[tex] = 310 - 159.03[/tex]
[tex] = \tt150.97 \: grams[/tex]
Thus, 150.97 grams of the element will remain after nine minutes.
We can round off 150.97 to 151.00.
Therefore, 151.00 grams of the element will remain after 9 minutes.
