Answer:what’s the initial age
Step-by-step explanation:
Paolo is using his grandmother's breakfast bar recipe. He always doubles
the amount of yogurt and oats. The recipe calls for 2 1/2 cups of
yogurt.
The total amount of yogurt and oats after doubling is 6 1/3 cups. Write an
equation to find the original amount of oats in the recipe.
I just need the equation i don't need the answer!!!! pls help me!!!!
Answer:
[tex]6\frac{1}{3}[/tex] = [tex]2\frac{1}{2}[/tex] * 2 + [tex]\frac{x}{2}[/tex]
Step-by-step explanation:
lets start with what we know.
the recipe calls for 2 [tex]\frac{1}{2}[/tex] cups of yogurt. and Paolo doubles the recipe. so multiply the recipe for yogurt by 2
2 [tex]\frac{1}{2}[/tex] * 2 = 5 cups of yogurt.
the total of yogurt and oats is [tex]6\frac{1}{3}[/tex] and we know how much yogurt we have so we subtract that from the total of both.
[tex]6\frac{1}{3}[/tex] - 5 = [tex]1\frac{1}{3}[/tex]
the oats after doubling were [tex]1\frac{1}{3}[/tex] cups so u divide it by 2
[tex]1\frac{1}{3}[/tex] / 2 = [tex]\frac{2}{3}[/tex] before doubling

1.Assume that 20 squirrels are put in an enclosed wildlife ranch and the squirrel population grows for the next 5 years, as shown in the table.
Year
Rabbit Population
0
20
1
80
2
320
3
1280
4
5120
5
20,480
Write a function that represents this.
2.A second group of 20 squirrels of a different breed is placed on a different ranch. The population of squirrels triples each year. Write an equation to model this situation.
3.Had the second group started with 40 squirrels instead of 20, which population will be bigger by year 3 and by how much?
Answer:
For the first group we have the pairs:
year population
0 20
1 80
2 320
3 1,280
4 5,120
5 20,480
Here we can see that the population quadruples each year
(4*20 = 80, 80*4 = 320, 320*4 = 1,280, etc...)
then the population equation is:
P(0) = 20
P(1) = 20*4
P(2) = (20*4)*4 = 20*4^2
We already can see the pattern, then we can write this relationship as:
P(t) = A*(4)^(t)
Where:
t represents time in years, and A is the initial population, that we know it is 20, then:
P(t) = 20*(4)^t
This is the function that represents the table.
B) Now we have a group of 20 squirrels and the population triples each year, with the same reasoning than before we can write the equation that models this situation as:
Q(t) = 20*(3)^t
C) Now, if the initial population of the second group is 40, the equation becomes:
Q(t) = 40*(3)^t
The population by year 3 is given by replacing t by 3, then:
Q(3) = 40*(3)^3 = 1080
And the population of the other group in year 3 is seen in the table, it is 1,280, then the population of the first group is bigger by year 3, and it is greater by:
1,280 - 1,080 = 200
So the first group is larger by 200 squirrels.

1. Express the following expression in the form y = a(x - h)? + k
y = - x² + 4x +1
Answer:
Step-by-step explanation:
y = -x² + 4x + 1
factor out the leading coefficient
y = -(x² - 4x) + 1
complete the square
y = -(x² - 4x + 2²) + 2² + 1
y = -(x-2)² + 5

Why 28, 60 and 120. tell me each step please?
Answer:
down here
Step-by-step explanation:
Exterior angles is the sum of the two opposite angles
so 100 - 72° = x
x = 28°
thats how you get 28°
720° is the sum of angles in a regular hexagon
720 / 6 = 120°
So the interior is 120°
To find the exterior angle, simply subtract the interior degree from 180.
external degree = 180 - 120 = 60
The exterior angle of a regular hexagon is 60 degrees.
Step-by-step explanation:
Alright, so over here, the triangle is called an exterior angle. When there is a line outside the triangle.
And the line outside the triangle means that the line outside is equal to the 2 other angles.
So in this case, it would be 100 = 72 + x.
Now let's do 100 - 72 to get the missing x.
100 - 72 is 28, right?
So our answer is 28.
Now the next one.
Regular hexagons interior angle sum using the formula (n-2) × 180 = (6-2)×180 = 4 × 180° = 720°
every interior angle then would be 720/6 = 120°
Now exterior angles are always 360°
so all angles = 360/6 = 60º.

Avery has a loyalty card good for a discount at her local pharmacy. The item she wants to buy is priced at $6, before discount and tax. After the discount, and before tax, the price is $5.04. Find the percent discount.
Answer:
16%
Step-by-step explanation:
$6 divided by $5.04 = 0.84
0.84 x 100 = 84%
100 - 84 = 16
6 - 5.04 = 0.96
0.96 divided by 6 = 0.16
0.16 x 100 = 16
