Answer:
The answer to your question is Angelica 19, her mom = 11
Step-by-step explanation:
Data
Angelica has 8 more than her mother
total number of shoes = 30 pairs
The Number of pairs Angelica has = a = ?
The Number of pairs her mother has = m = ?
Process
1.- Write two equation that help to solve this problem
a = m + 8 Equation l
a + m = 30 Equation ll
2.- Solve the system of equations by substitution
Substitute equation l in equation ll
(m + 8) + m = 30
-Solve for m
m + 8 + m = 30
2m = 30 - 8
2m = 22
m = 22/2
m = 11
3.- Find a
a = 11 + 8
a = 19
4.- Conclusion
Angelica has 19 pairs of shoes and her mom has 11
89/9 = 9 8/9 <== ur mixed number
After 30 minutes from the time recipe is kept in the oven, then the temperature of the oven is kept at 350 °F.
<h3>What is a function?</h3>
The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
A pumpkin pie recipe says to bake the pie at 425°F for 15 minutes, and then to adjust the temperature down to 350°F for 45 additional minutes.
The function P(t) gives the oven temperature setting t, in degrees Fahrenheit, t minutes after the pie is placed in the oven.
Diego discovers that the temperature inside the oven is always 25 degrees warmer than the oven’s temperature setting.
The function B gives the actual temperature of Diego’s oven.
If P(30) = 350. Then the corresponding point on the function B will be
The temperature function can be written as
The value of t = 30 lies in the interval of 15 < t ≤ 60.
After 30 minutes from the time recipe is kept in the oven, then the temperature of the oven is kept at 350 °F.

Answer:
vertex = (0, -4)
equation of the parabola:
Step-by-step explanation:
Given:
- y-intercept of parabola: -4
- parabola passes through points: (-2, 8) and (1, -1)
Vertex form of a parabola:
(where (h, k) is the vertex and is some constant)
Substitute point (0, -4) into the equation:
Substitute point (-2, 8) and into the equation:
Substitute point (1, -1) and into the equation:
Equate to find h:
Substitute found value of h into one of the equations to find a:
Substitute found values of h and a to find k:
Therefore, the equation of the parabola in vertex form is:
So the vertex of the parabola is (0, -4)
Answer:
divide 7/100 which is 0.07
multiply that by 13.75, and you get 0.96
13.75+0.96= $13.20
