Answer: 20/189
Step-by-step explanation: Y is proportional to x which states that 4/63 is proportional to 3 so when x=5 then it will be 5*4/63/3=20/63/3=20/63*1/3=20/189

In the 1980s, Earth had about five months of very hot weather. In the 1990s, Earth had about
22 months of very hot weather. What is the percent increase in hot weather months from the
1980s to the 1990s? Round to the nearest percent.
Answer:
340%
Step-by-step explanation:
1980s = 5 months of very hot weather
1990s = 22 months of very hot weather
What is the percent increase in hot weather months from the
1980s to the 1990s?
Percent increase = (22 months - 5 months) / 5 months × 100
= 17 / 5 × 100
= 3.4 × 100
= 340%
Percent increase in hot weather months from the 1980s to the 1990s is 340%

Mr. Majors ordered six hot dogs and a bucket of popcorn at the concession stand. If the popcorn
was $3.20, and the total was $18.20, what was the price of one hot dog?
Answer:
The cost of one hot dog is $2.50
Step-by-step explanation:
You need to subtract $3.20 from $18.20 to get $15.00. Then you need to divide $15.00 by 6 to get $2.50.
A company produces circular drink coasters. The equation x2 y2 = 18. 0625, with units in inches, represents the size of a coaster. Each coaster is cut from a square piece of cardboard. What is the minimum possible area of each cardboard piece? 4. 25 in2 8. 5 in2 18. 0625 in2 72. 25 in2.
The minimum possible area of the square cardboard will be given as
[tex]a= 72.2\ in ^2[/tex]
What will be the area of the dashboard?The area of the square is the product of its two lengths.
We have an equation of the circular drink coaster
[tex]x^2+y^2=18.0625[/tex]
Comparing the above equation from the general form of the circle
[tex]x^2+y^2=r^2[/tex]
We can see that from the equation
[tex]r^2=18.0625[/tex]
[tex]r=4.25\ inch[/tex]
Diameter [tex]d=4.25\times 2=8.50[/tex]
The diameter will be the length of the square since the circle is cut from the square.
So the area of the square will be
[tex]a=d\times d=8.50\times 8.50=72.25\ inch^2[/tex]
Thus the minimum possible area of the square cardboard will be given as [tex]a= 72.2\ in ^2[/tex]

Which of the following number lines and solution sets show the values of r that make the inequality -2r+3<9 true
Answer:
"Solving'' an inequality means finding all of its solutions. A "solution'' of an inequality is a number which when substituted for the variable makes the inequality a true statement. When we substitute 8 for x, the inequality becomes 8-2 > 5. Thus, x=8 is a solution of the inequality.
Step-by-step explanation:
Example 1:
Consider the inequality
displaymath173
The basic strategy for inequalities and equations is the same: isolate x on one side, and put the "other stuff" on the other side. Following this strategy, let's move +5 to the right side. We accomplish this by subtracting 5 on both sides (Rule 1) to obtain
displaymath174
after simplification we obtain
displaymath175
Once we divide by +2 on both sides (Rule 3a), we have succeeded in isolating x on the left:
displaymath176
or simplified,
displaymath177
All real numbers less than 1 solve the inequality. We say that the "set of solutions'' of the inequality consists of all real numbers less than 1. In interval notation, the set of solutions is the interval tex2html_wrap_inline187 .
Example 2:
Find all solutions of the inequality
displaymath189
Let's start by moving the ``5'' to the right side by subtracting 5 on both sides (Rule 1):
displaymath190
or simplified,
displaymath191
How do we get rid of the ``-'' sign in front of x? Just multiply by (-1) on both sides (Rule 3b), changing " tex2html_wrap_inline201 " to " tex2html_wrap_inline203 " along the way:
displaymath192
or simplified
displaymath193
All real numbers greater than or equal to -1 satisfy the inequality. The set of solutions of the inequality is the interval tex2html_wrap_inline205 .
Example 3:
Solve the inequality
displaymath207
Let us simplify first:
displaymath208
There is more than one route to proceed; let's take this one: subtract 2x on both sides (Rule 1).
displaymath209
and simplify:
displaymath210
Next, subtract 9 on both sides (Rule 1):
displaymath211
simplify to obtain
displaymath212
Then, divide by 4 (Rule 3a):
displaymath213
and simplify again:
displaymath214
It looks nicer, if we switch sides (Rule 2).
displaymath215
In interval notation, the set of solutions looks like this: tex2html_wrap_inline227 .
hi can someone help me with my question, which is 2 ( 3 + x) - 7 = x + 5?
Answer: x=6
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*(3+x)-7-(x+5)=0
(2 • (x + 3) - 7) - (x + 5) = 0
x - 6 = 0
Solve : x-6 = 0
Add 6 to both sides of the equation :
x = 6
Answer:
x = 6
Step-by-step explanation:
2(3+x)-7=x+5
We move all terms to the left:
2(3+x)-7-(x+5)=0
We add all the numbers together, and all the variables
2(x+3)-(x+5)-7=0
We multiply parentheses
2x-(x+5)+6-7=0
We get rid of parentheses
2x-x-5+6-7=0
We add all the numbers together, and all the variables
x-6=0
We move all terms containing x to the left, all other terms to the right
x=6

To find the sum of interior angles of this polygon you have to use the equation
S=180(n-2)
where n is the number of sides
S=180(6-2)
S=180(4)
S=720 degrees
The sum of all angles is 720 degrees
[tex]110 + x + 25 + x - 30 + x + x + 115 = 720[/tex]
[tex]4x = 720 - 110 - 25 - 115 + 30[/tex]
[tex]4x = 720 - 220[/tex]
[tex]4x = 500[/tex]
[tex]x = \frac{500}{4} = 125[/tex]

Which algebraic property is used to rewrite 2(4y + 1) as (4y + 1)(2)?
Answer:
Commutative property of multiplication
Step-by-step explanation:
The line y = 0.5x + 8 passes through (-10, a) and (-20, b). Find the values of a and b.
Answer:
Step-by-step explanation:
Write out the equation y = 0.5x + 8. Now focus on the point (-10, a). In the given equation, let y = a and x = -10: a = 0.5(-10) + 8, so that a = 3.
Next, focus on the point (-20, b). Find b: In y = -0.5x + 8, replace x with -20 and y with b: b = 0.5(-20) + 8, or b = -10 + 8, or b = -2

When he drove out of the car park he had to pay 8.40 euros.
At what time did Jon drive out of the car park?
Answer:
Given : car park charges 0.018 euros per minute.
claude parked his car in this car park at 13:15.
he had to pay 4.50 euros.
To Find : at what time did claude drive out of the car park
Solution:
car park charges per minute = 0.018 euros
Parking Charges paid = 4.50 Euros
Time car parked for = 4.50/0.018
= 250 minutes
= 4 hr 10 minutes
parked his car at 13:15
Parked for 4 hr 10 min
claude drive out of the car park = 13+4 = 17 hr
15 + 10 = 25 min
claude drive out of the car park at 17 : 25

What is Division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.
Here, car park charges 0.024 euros per minute.
Jon parked his car in this car park at 10:45.
he had to pay 8.40 euros.
Time car parked for = 8.40/0.024
= 350 minutes
= 5 hrs 50 minutes
parked his car at 10:45
Parked for 5 hrs 50 mins
Jon drive out of the car park = 10:45 + 5:50
= 16:35
Thus, Jon drive out of the car park at 16 : 35 .

Which segment is a diameter of this circle?
Ο TX
O VX
Ο XY
Answer:
The answer is VX.
Step-by-step explanation:
This is because the line segment VX, reaches from one end of the circle to the other, touch both sides of the circle. The other options do not make sense since segment XY does not go through the center of the circle and TX is the radius of the circle. The radius is half the diameter of the circle.
Therefore, the answer is VX.

An angle measures 6° more than the measure of its complementary angle. What is the measure of each angle?
Answer:
42° and 48°
Step-by-step explanation:
Complementary angles add up to 90°.
So we have one angle x and the other angle x+6 which when added together will equal 90°.
x + x + 6 = 90
2x + 6 = 90
-6 - 6
2x = 84
Divide both sides by 2
2x/2 = 84/2
x = 42
So one angle = 42°, and the other angle = 42° + 6° = 48°.

The harmonic mean of two positive integers is the reciprocal of the arithmetic mean of their reciprocals. For how many ordered pairs $(x,y)$ of positive integers is the harmonic mean of $x$ and $y$ equal to $20$
Answer:
9 ordered pairs
Step-by-step explanation:
The requirement that the harmonic mean of two positive integers be 20 places a restriction on what those integers may be.
20 = 2/(1/x +1/y)
y = 10x/(x -10)
Integer values of x that produce integer values of y are ...
x ∈ {11, 12, 14, 15, 20, 30, 35, 60, 110}
The corresponding 9 ordered pairs are ...
(11, 110), (12, 60), (14, 35), (15, 30), (20, 20), (30, 15), (35, 14), (60, 12), (110, 11)
