A stray dog ate 4 of your muffins. That was 2/9 of all of them! How many are left?
Answer:
14muffins are left. please give brainliest
Step-by-step explanation:
so first we need to figure out how many there are in total so if 4 muffins is 2/9 so every 2 muffins is 1/9 so we need 9x2 wich is 18 so there are 18 muffins in total but the stray dog ate 4 of them so 18-4 is 14 so the answer is 14muffins are left.

10. Write About It Meredith describes to Liza two purchases she made.
"On Monday, I bought 39 books and 21 CDs for $396. On Tuesday, at the
same prices, I bought 52 books and 28 CDs for $518."
Liza thought about the numbers and said, "That's impossible!" Is Liza
correct? Assume that all books cost the same amount and all CDs cost
the same amount. Explain.
Answer:
Yes, because the 39 books and 21 cds price is proportional to the 52 books and 28 cds' price

In a walk-a-thon a sponsor will donate $20 and an additional $3 for each mile the participant walks. What is the rate of change in the situation? Fill in your answer in the boxes below.
Answer:
20 + 3x or +3 per mile
Step-by-step explanation:
A customer buys
3
shirts that cost
$
10
each. The store is having a sale for
15
%
off, and the sales tax is
6
%
. The store applies discounts before applying the sales tax to a customer’s total.
What is the customer’s total after the discount and sales tax are applied, in dollars and cents?
Answer:
4.77
Step-by-step explanation:
3 x 10 = 30
30 % 15 = 4.5
4.5 % 6 = 0.27
0.27 + 4.5 = 4.77
Justify each step and simplify the equation.
19+56(1/56)
Answer:

It's not a typo that both answers are 24
======================================================
Explanation:
Each time the weight goes up by 1 ounce, the cost goes up by 24 cents. So the unit cost is 24 cents per ounce. This is exactly the slope of the line because the slope is the rate of change. It tells us how fast something is changing.
You can use the slope formula to answer this question, but I think it's easier to simply locate the point (1,24) and then note that slope = rise/run = y/x = 24/1 = 24. This shortcut only works because the line goes through the origin.
The equation of this line is y = 24x
x = number of ounces
y = cost in cents
Step-by-step explanation:both are 24

Tori, Brielle, and Abby, go shopping together. Together they spend $215. Brielle spends twice as much as Tori, and Abby spends one dollar less than three times what Tori spends. How much did each girl spend?
Step-by-step explanation:
Tori + Brielle + Abby = 215
Give Tori spends x.
Brielle ; 2x and Abby ; 3x - 1
so
x + 2x + 3x - 1 = 215
6x - 1 = 215
6x = 216
x = 36
Tori spends $36 Brielle spends $72 and Abby spends $107.

The circular top of a clay pot has a diameter of 14 centimeters . What is the circumference of the pot's circular top ? Use 3.14 for π
Answer:
Circumference formula is πr². while we do not have the radius, you do have the diameter, the diameter is the full length of the circle while the radius is half of the circle. So you take 14/2=7 so the new equation is π7² so you would do 7x7 to get 49, then you would do 49 x 3.14 and you'll have 153.86 Centimeters². You'll need to double check this but I hope this helped.

two complementary angles are in a ration of 2 3 find the measure of each angle
A complementary angle is 90 degrees. The ratio is 2:3 so the equation would be:
2x+3x=90
5x=90
x=18
One of the angles would be 2(18) or 36 degrees and the other angle would be 3(18) or 54 degrees.
36+54 is equal to 90 degrees so it checks out.

qenl ingin ke korea menemui Mbak Rrr, qenl mmbeli tiket delman dgn harga 5000 tapi uangnya hanya cukup untuk pergi ke kanada yg harga tiket delmannya 2000. berapa selisih kedua tiket tsb?
nt:
how to make a username with greek letters
Answer:
3.000
Step-by-step explanation:
ticket delman korea = 5000ticket delman kanada = 2000Selisih
= 5000 - 2000
= 3000
Maka, selisih harga tiket delman Korea & Kanada adalah 3.000 .
Tiket to Korea = 5.000
Tiket to Kanada = 2.000
—» Selisih = Tiket Korea - Tiket Kanada
—» Selisih = 5.000 - 2.000
—» Selisih = (5 - 2)000
—» Selisih = 3.000
A fitness trainer decided to track the combined weight loss of
several new customers. She recorded the combined weight loss
each month and kept track for 6 months. Identify the best
mathematical model with its corresponding R2 value and tell
whether it is a good model.

exponential model, 0.996
Yes, 0.996 is very close to 1.
quadratic model, 0.994
Yes, 0.994 is very close to 1.
quadratic model, 0.994
No, 0.994 is too high an R2 value.
exponential model, 0.996
No, 0.966 is too high an R2 value.
Now, the R² value comes out as 0.996 and it is an exponential model and it is close to 1. Hence, option A is correct.
What is an exponential model?
Quantity rises over time through a process called exponential growth. It happens when the derivative, or instantaneous rate of change, of a quantity with respect to time is proportionate to the original quantity. A quantity that is growing exponentially is referred to as an exponential function of time, meaning that the exponent is the variable that represents time (in contrast to other types of growth, such as quadratic growth).
The amount declines over time and is said to be experiencing exponential decay if the constant of proportionality is negative. It is also known as geometric growth or geometric decay when the discrete domain of definition has equal intervals since the function values form a geometric progression.
Given that a fitness trainer is tracking the combined weight loss of several new customers.
She is recording for 6 months.
Now, we have to find the best mathematical model with the corresponding R² value
Given, the combined weight loss are - 175, 120, 95, 63, 44 and 30.
The formula for coefficient of determination R² = (x-x')(y-y')/√∑(x-x')²(y-y')²
≈ 0.996
Now, the R² value comes out as 0.996 and it is an exponential model and it is close to 1. Hence, option A is correct.
