Answer:
The hight of each floor is 8(ft).
Step-by-step explanation:
If you divide 816(ft) by 102 floors you will get 8(ft) making each floor 8(ft) because the building's hight divided by the floors would make an amount of the hight of each floor.

Amelia can spend no more than $89 to rent a car for a day trip. A rental car costs $35 per day plus $0.20 per mile. Write and solve an inequality to find the possible distance in miles m that Amelia can drive without exceeding her budget.
Answer:
35 + 0.20m ≤ 89
m = 270
Step-by-step explanation:
35 + 0.20m ≤ 89
- 35 -35
0.20m ≤ 54
÷.20 ÷.20
m = 270

Rodrigo and Melissa went to the art supply store to buy drawing materials. Rodrigo bought 10
pencils and 7 felt-tip markers for a total of $19.00. Melissa bought 3 pencils and 5 felt-tip markers
for a total of $10.05. Which of the following systems of equations could be used to determine
the cost of one pencil, P, and one felt-tip marker, m?
Answer:
10P + 7m = 19 .......... 1
3P + 5m = 10.05 .......... 2
Step-by-step explanation:
Let the cost of pencil be represented by P, and felt-tip by m. So that;
Rodrigo bought 10 pencils and 7 felt-tip at the cost of $19.0.
⇒ 10P + 7m = 19 .......... 1
Melissa bought 3 pencils and 5 felt-tip at the cost of $10.05.
⇒ 3P + 5m = 10.05 .......... 2
From equations 1 and 2,
10P + 7m = 19 .......... 1
3P + 5m = 10.05 .......... 2
Multiply equation 1 by 3, and 2 by 10 to have;
30P + 21m = 57 ......... 3
30P + 50m = 100.5 ....... 4
Subtract equation 3 from 4,
30P - 30P + 50m - 21m = 100.5 - 57
29m =43.5
m = [tex]\frac{43.5}{29}[/tex]
= 1.5
m = 1.5
Substitute the value of m in equation 2,
3P + 5m = 10.05 .......... 2
3P + 5(1.5) = 10.05
3P = 7.5 = 10.05
3P = 3
P = 1.0
Thus, the cost of a pencil is $1.0 and that of a felt-tip is $1.5.

Can someone explain how the quadratic equation works with an example!
Answer:The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.
Step-by-step explanation: 6x² + 11x - 35 = 0.
2x² - 4x - 2 = 0.
-4x² - 7x +12 = 0.
20x² -15x - 10 = 0.
x² -x - 3 = 0.
5x² - 2x - 9 = 0.
3x² + 4x + 2 = 0.
-x² +6x + 18 = 0.

Amelia runs a catering business. Based on her records, her weekly profit can be modeled by P=-2x^2+152x-150P=−2x 2 +152x−150, where xx is the number of meals she caters and PP is her profit.
Answer:
The least number of meals Amelia needs to cater in order to begin making profit = 38 meals.
Step-by-step explanation:
Given - Amelia runs a catering business. Based on her records, her weekly
profit can be modeled by P= -2x² + 152x - 150, where x is the
number of meals she caters and P is her profit. When P is negative,
Amelia losses money.
To find - What is the least number of meals Amelia needs to cater in order
to begin making profit.
Proof -
As given, P = -2x² + 152x - 150
Now,
Above the break-even point, she only get profit
The break -even point is a point where there is no profit, and no loss.
Now,
For break-even point,
[tex]\frac{dP}{dx} = 0[/tex]
⇒[tex]\frac{d}{dx}( -2x^{2} + 152x - 150) = 0[/tex]
⇒-4x + 152 = 0
⇒- 4x = - 152
⇒4x = 152
⇒x = [tex]\frac{152}{4}[/tex] = 38
∴ we get
If Amelia caters at least 38 meals , then she makes Profit.
Which of the following tables of values could not represent a function?
A)

Answer:
B
Step-by-step explanation:
Answer:
B) is not a function
Step-by-step explanation:
For an table to be a function the y axis all have to be different from each other but on B it is not, it is only 1, therefore B is not a function

The mass of Parcel A was 0.7 kg. Parcel B was heavier than Parcel A.
Parcel C had the same mass as Parcel B. The total mass of the three
parcels was 2.5 kg. What was the mass of Parcel C?
Answer: 0.9kg
Step-by-step explanation:
Since we are informed that Parcel C had the same mass as Parcel B, let their mass be represented by x.
Therefore,
Parcel A + Parcel B + Parcel C = 2.5
0.7 + x + x = 2.5
0.7 + 2x = 2.5
2x = 2.5 - 0.7
2x = 1.8
x = 1.8/2
x = 0.9
The mass of parcel C is 0.9kg
