The income elasticity of demand for food is 1.
What is income elasticity of demand?
The income elasticity of demand measures how quantity demanded changes when income changes.
income elasticity of demand = percentage change in quantity demanded / percentage change
When income elasticity of demand is one, it means that the good has a constant demand regardless of changes in income.

Help!!!! ( this is i-ready )
Answer:
Take the values in the box:
IQTR = 16 - 7
= 9
Can someone help me please and have an explanation :)
Answer:
ok so lets find the difference on the table
from 5 to 8 is goes up 250.5(668-417.5)
so that means 3 tickets goes 250.5 so lets divide by 3
250.5 divide by 3=83.5 per ticket
83.5*6=501
501
Hope This Helps!!!
Answer:
Equation : $83.50x = Cost of the tickets
(where x = number of tickets)
Cost of 6 tickets : $501
Step-by-step explanation:
I'm not sure if this is the way they want you to do it, but what I did is :
1) Solve a proportion to figure out the cost of 1 ticket
5/417.50 = 1/x
5x = 417.50(1)
5x/5 = 417.50/5
x = 83.50
So, the cost of 1 ticket is $83.50
2) Create an equation
If x equals the number of tickets :
83.50x = Cost of the tickets
3) Solve for 6 tickets
83.50(6) = Cost of the tickets
501 = Cost of the tickets
Substitute x for the number of tickets, which is 6 and you'll get $501 :)

Which equation is NOT true?
Answer:
B
Step-by-step explanation:
Using the method of cross- multiplication
[tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex] ⇒ ad = bc
If ad ≠ bc then equation is not true
A
[tex]\frac{10}{12}[/tex] = [tex]\frac{5}{6}[/tex] , then
10 × 6 = 12 × 5 = 60 ← equation is true
B
[tex]\frac{69}{100}[/tex] = [tex]\frac{6}{10}[/tex] , then
69 × 10 = 690 and 100 × 6 = 600
690 ≠ 600 ← equation not true
C
[tex]\frac{10}{5}[/tex] = [tex]\frac{200}{100}[/tex] , then
10 × 100 = 5 × 200 = 1000 ← equation is true
D
[tex]\frac{12}{4}[/tex] = [tex]\frac{6}{2}[/tex] , then
12 × 2 = 4 × 6 = 24 ← equation is true
Hi!
I can help you with joy! :)
• Here, we need to determine if each equation is true by simplifying fractions.
• The 1st equation states that
10/12 = 5/6
Is it true?
Let’s simplify 10/12 to find out.
Divide 10 and 12 by 2:
5/6
Thus. The 1st equation is true.
How about the next one?
We have 3 options left.
69/100=6/10
Is that correct?
Nope!
Why?
If we simplify 69/100, we will not get 6/10.
In fact, 69/100 cannot be simplified.
Thus, the second equation is not true.
Now, how about Options C and D?
Well, both of these equations ARE true.
Thus, the second equation is not true.
Hope it helps.

Chris buys 2 identical bags of cherries to make a pie.
There are more than 10 but less than 30 cherries in each bag.
Chris eats 7 cherries, then uses half of the rest in his pie.
Chris uses 11.5 cherries for his pie.
How many cherries were in each bag to start with?
==================================================
Explanation using mental math:
He uses 11.5 cherries for his pie, which is half the amount left (after eating those 7 cherries).
This means 2*11.5 = 23 cherries were left over after he ate those seven. In other words, half of 23 is 11.5
If we reverse time, then we get those 7 cherries back to get 7+23 = 30 cherries total. Divide those up equally between the two bags and we get 30/2 = 15 cherries per bag.
Going forward in time we have 15 cherries per bag, so 2*15 = 30 total. He eats 7 to be left with 30-7 = 23 cherries. That cuts in half to 23/2 = 11.5 cherries for his pie.
---------------
Explanation using algebra
c = number of cherries in each bag.
10 < c < 30 based on the second sentence
2c = number of cherries total from both bags combined
2c-7 = the amount left after Chris eats those 7 cherries
(2c-7)/2 = he uses half of the remaining cherries for the pie
Set that equal to the 11.5 number stated and solve for c.
(2c-7)/2 = 11.5
2c-7 = 11.5*2
2c-7 = 23
2c = 23+7
2c = 30
c = 30/2
c = 15
We effectively follow similar steps as when we did the mental math route.
Notice how c = 15 makes 10 < c < 30 true.

Given Trapezoid JOKE with m
Answer:
Step-by-step explanation:
In trapezoid JOKE, JO // EK
m∠J + m∠E = 180 {so-interior angles are supplementary }
m∠J +80 = 180
m∠J = 180 - 80
m∠J = 100
m∠O + m∠K = 180 {Co-interior angles are supplementary}
m∠O + 50 = 180
m∠O = 180 -50
m∠O = 130

The radius of the circle expressed as a mixed number is: [tex]3\frac{11}{12}[/tex] inches.
What is the Radius of a Circle?Radius of a circle = half the measure of the diameter of a circle.
Given:
diameter of a circle = [tex]7\frac{5}{6}[/tex] inches
Therefore:
Radius of the circle = 1/2([tex]7\frac{5}{6}[/tex])
= 1/2(47/6)
= (1 × 47)/(2 × 6)
= 47/12
= [tex]3\frac{11}{12}[/tex] inches.
Therefore, the radius of the circle expressed as a mixed number is: [tex]3\frac{11}{12}[/tex] inches.

What is the length of the base of a right triangle with an area of 15 square meters and a height of 3 meters?
5 m
10 m
30 m
45 m
The area of a right triangle is the amount of space on it
The length of the base is 10 meters
How to determine the length of the baseThe given parameters are:
Area = 15 square meters
Height = 3 meters
The area of the triangle is:
Area = 0.5 * Base * Height
So, we have:
15 = 0.5 * Base * 3
Divide both sides by 0.5
30 = Base * 3
Divide both sides by 3
10 = Base
Rewrite as:
Base = 10
Hence, the length of the base is 10 meters

Solution :
Let the required expression to be subtracted be x
⇢ a² – 7ab + 3b² – x = – 4a² + 6ab + 3b²
⇢ a² – 7ab + 3b² – (– 4a² + 6ab + 3b²) = x
⇢ a² – 7ab + 3b² + 4a² – 6ab – 3b² = x
Combining the like terms :
⇢ a² + 4a² – 7ab – 6ab + 3b² – 3b² = x
⇢ 5a² – 13ab = x
⇢ x = 5a² – 13ab
Therefore,
5a² – 13ab should be subtracted from a² – 7ab + 3b² to get – 4a² + 6ab + 3b².
