Answer: No. It's not proportional
Step-by-step explanation:
The direct proportion in mathematics is expressed as:
y = kx
where
y = $200
k = constant
x = $7.50
We then solve for k
y = kx
200 = 7.50k
k = 200/7.50
k = 26.67
Since k isn't a whole number, then the amount of money in her bank account proportional to the number of pumpkin she sells.
Answer: The original price of the jacket is given in the question and it is $68.
The percent of discount given on the original price is 30%.
Then
The amount of discount given = (68 * 30/100) dollar
= 20.4 dollar
The discount amount is $20.4
Now after the deduction of the sale percentage, the selling price of the jacket can be easily deduced.
Then
Selling price of the jacket = (68 - 20.4) dollars
= 47.6 dollars

Answer:
Use area of trap formula and special right triangles
Step-by-step explanation:
A = (.5)(10 + 18)(5)
Answer: y= -1x + 5
Step-by-step explanation:
(-3,8) ( 4,1)
8-1= 7
-3-4 = -7
7/-7 = -1 so the slope is -1 so we will use the formula y=mx+b to find the y-intercept
8= -1(-3) + b
8= 3 + b
-3 -3
b= 5 so the y intercept is 5 now we will write the equation like this y= -1x + 5
