Answer:
Step-by-step explanation:
a) Let the cost of a Pizza = $ x
Cost of three pizza's = 3 *x = 3x
cost of 3 pizza + cost of a salad = $ 20.7
3x + 3 = 20.7
b) 3x + 3 = 20. 7 {Subtract 3 from both sides}
3x = 20.7 - 3
3x = 17.7 {Divide both sides by 3}
x = 17.7/3
x = 5.9
Cost of one pizza = $ 5.9

On the Celsius scale, the freezing point of water occurs at zero. Which pair of numbers represents temperatures both above and below the freezing point?
–10°C and –20°C
5°C and –10°C
0°C and 10°C
20°C and 5°C
The temperature above and below the freezing points are 5°C and –10°C respectively. The correct option is B.
What is the freezing point?The temperature at which a liquid begins to solidify Melting point is the temperature at which the liquid and solid states of a substance are in equilibrium at atmospheric pressure. Water has a freezing point of 0° Celsius or 32° Fahrenheit.
The freezing point of the water is 0 degrees Celcius. It means that below 0 degrees like in negative temperature water becomes ice. Above 0 degrees Celcius the water remains in a liquid form.
Therefore, the temperature above and below the freezing points are 5°C and –10°C respectively. The correct option is B.

What is the difference between mean and median
The difference between the mean and median is that the mean is the average number. f.e: 1, 2, 2, 2, 3, 3, 4, 5 - and if you add all those up, the mean would be 3, or 2.
But the median is the number in the middle Number.
What if you have 2 medians, though?
Well, that’s easy to solve IMO.
F.e: 22, 22, 23, 23, 23, 24, 24, 24, 25, 25
The median is either 23 or 24, right?
Okay. That’s simple. But what exactly do we do?
Let me show you:
So get the sum of 23 and 24, which is 47.
Now divide 47 by 2. And what do we get?
23.5.
Now round that, and you get 24. So 24 is the median!
Hope that helps!
Answer:
mean is the AVERAGE of all numbers
Step-by-step explanation:
because when you add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS!
and a median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.

You have 15 yards of ribbon for your gift boxes. Each box gets the same amount of ribbon. How much ribbon will each of your 20 gift boxes get?
Answer:
3/4 of a yard or 0.75 of a yard for each gift box.
Step-by-step explanation:
15 yards of ribbons
20 gift boxes
20/15 = 0.75
0.75 would be split evenly for all 20.
Answer:
2.25 feet
Explanation:
You would get 0.75 yards because 20 boxes divided by 15 yards is 0.75 yards

Nancy is going to pick a marble out of a bag without looking. There are three different colors- blue, red, and purple. The probability of choosing a blue marble is .25, and the probability of picking a red marble is ⅔ . What is the probability of Nancy picking a purple marble?
A. 1/12
B. 1/6
C. 1/3
D. 2/3
Probability 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.
The probability of Nancy picking a purple marble is 1/12
Option A is the correct answer.
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.
We have,
There are three different colors- blue, red, and purple.
The probability of choosing a blue marble is 0.25
The probability of picking a red marble is 2/3
The total probability of always 1.
The probability of Nancy picking a purple marble.
= 1 - (0.25 + 2/3)
= 1 - (1/4 + 2/3)
= 1 - (3 + 8)/12
= 1 - 11/12
= 1/12
Thus,
The probability of Nancy picking a purple marble is 1/12
Option A is the correct answer.

What is the perimeter of the object (Hint: Not all numbers should be used to find your answer) (Provide number only in your answer) *
Answer:
27 IN
Step-by-step explanation:
If you want to calculate the perimeter of an irregular trapezoid, there's no special formula - just add all four sides:
Trapezoid perimeter = a + b + c + d
Maybe you've noticed, but it's the formula for any quadrilateral perimeter.
There's also an option that that presents itself with certain special trapezoids - like an isosceles trapezoid, where you need a, b, and c sides. Another example is a right trapezoid, where the length of the bases and one leg are enough to find the shape's perimeter (the last leg is calculated using Pythagoras' Theorem).

The second of three numbers is 8 more than the first,
and the third number is 3 less than 3 times the first.
If the third number is 15 more than the second, find
the three numbers.
Answer: The numbers in order are 13, 21, 36
Step-by-step explanation:
First of all, we must convert all the information given in the question into equations so we can look it from a simplified angle, and hence, solve it.
So, let's start off by giving each of the unknown numbers a name. Let's call the first number a, the second number b, and the third number c.
Therefore:
"The second of three numbers is 8 more than the first" gives us:
b = 8 + a
"... the third is 3 less than 3 times the first" gives us:
c = 3a - 3
and "the third number is 15 more than the second" gives us:
c = 15 + b
Now, we can substitute b = 8 + a into c = 15 + b, to get:
c = 15 + (8 + a), which simplified gives us:
c = 23 + a
With that done we can use elimination.
We've got c = 23 + a, and c = 3a - 3. We want to eliminate 'a', so we should multiply both sides of c = 23 + a by (-3) to get: -3c = -69 - 3a.
Now we can eliminate the 'a' variable:
c = 3a - 3
-3c = -3a - 69
-------------
-2c = -72
Therefore, we can solve for 'c' by dividing both sides by -2, which leaves us with:
c = 36
Now we can plug that value of 'c' into the equation c = 15 + b, to solve for b:
36 = 15 + b (Subtract 15 from both sides)
21 = b
Now that we've got a value for 'b', we can plug it into the equation b = 8 + a to solve for 'a':
21 = 8 + a (Subtract 8 from both sides)
13 = a
Sorry it's very long, but it's how I solved this
Hope this helped! ;)

buck is building a horse corral with the shape and dimensions shown in the sketch. He wants to make sure the corners of the corral measure 90 degrees
how long must diagonal AC be so angle B is a right angle?
uprgigt corner is D other side is C
Downleft is A across from B
16 ft down and 12 ft side
Answer:
BxA=F
Step-by-step explanation:
Diagonal AC must be 20 feet so that ∠B will be 90°.
According to asked question, buck is creating a horse coral by designing in such a way that corners will be at 90°.
So according to question we have to make ∠B as 90°.
So quadrilateral ABCD becomes a rectangular.
Therefore ΔABC will be a right-angle triangle in which we can use Pythagoras theorem to measure the diagonal AC.
What is Pythagoras Theorem?The Pythagoras Theorem says that in a right-angle triangle, the square of the hypotenuse is the sum of square of the other two sides of the right-angle triangle.
In the right-angle tringle ΔABC,
AC²=AB²+BC²
⇒ AC²=16²+12²
⇒ AC²=256+144=400
⇒AC=√400
⇒AC=20 feet
Therefore, Diagonal AC must be 20 feet so that ∠B will be 90°.
