Times are tough for Peter the Penguin and his "Hug a Penguin" business has been on the decline. Last year Peter the Penguin made $570 dollars from selling hugs. If he experienced a 20% decrease in sales how much did he make this year?
Answer:
the new sales after decrease in sales percentage this year is $456 dollars
Step-by-step explanation:
The computation of the sales made this year is shown below:
Given that
last year sales would be $570 dollars
And in this year there is 20% decrease in sales
so, the new sales after 20% decrease would be
= Last year sales × (1 - decreased percentage)
= $570 × (1 - 0.20)
= $570 × 0.80
= $456 dollars
hence, the new sales after decrease in sales percentage this year is $456 dollars
The equation for the line that has a slope of −38 and passes through (0, 10) is please help me with this problem.
Answer:
y = -38x + 10Step-by-step explanation:
Slope- intercept form:
y + mx = bGiven
m = -38 and point (0, 10)As per given point, y-intercept is b = 10
So the equation is:

What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
We have to given that;
Divide 2/8 by 9/18.
Now, We can divide the numbers as;
⇒ Divide 2/8 by 9/18
⇒ 2/8 ÷ 9/18
⇒ 2/8 × 18/9
⇒ 36/72
⇒ 1/2

19. Perimeter of rectangle = 2(l + b)
l = 25m
b = 16m
Perimeter of rectangular park = 2 (25 + 16)
= 50 + 32
= 82m
Perimeter of square park = 82m
(given that, perimeter of rectangular and square park are equal)
Perimeter of square = 4a
4a = 82
a = 82/4
a = 20.5m
Area of square park = a²
= 20.5²
= 420.25m²
20. Perimeter of regular hexagon = 6a

Step-by-step explanation:
A slug travels 3 centimeters in 3 minutes. A snail travels 6 centimeters in 6 minutes. Both travel at constant speeds. Mai says, “The snail was traveling faster because it went a greater distance.” Do you agree with Mai's reasoning
Answer:
No
Step-by-step explanation:
If you find the rate, they are the same.
3 minutes/3= 1 minute
3cm/3= 1 cm
Slug= 1 cm per minute
6 minutes/6= 1 minute
6cm/6= 1 cm
Snail= 1 cm per minute
The average of your 3 quiz grades is 17 points. Two of your quiz grades are 14 points and 19 points. Write and solve an equation to find the score of your third quiz.
Answer:
The equation would be 14+19+x=51, and the 3rd quiz score would be 18.
Step-by-step explanation:
To get to the average, you have to add all the quiz scores and divide by the number of quizzes. If you work backwards, you can multiply the average by the number of quiz scores, which is 51. Then you subtract the known test scores, and you get your answer.
