Answer:
(-16x + 13)° + (-20x + 23)° = 180° (ángulo recto)
-16x° + 13° - 20x° + 23° = 180°
-36x° + 36° = 180°
-36x° = 180° - 36°
-36x° = 144°
-x° = 144°/(-36)
x° = 36°

Answer:
1. 8.4 2. 15
Step-by-step explanation:
1. 4x + 8y = 40
when y = 0.8
4x + 8 × 0.8 = 40
4x = 40 - 8 × 0.8
4x = 40 - 6.4 = 33.6
....x = 33.6 / 4 = 8.4
2. 3a + b = 54
when b = 9
3a + 9 = 54
3a = 54 - 9
3a = 45
.....a = 45 / 3 = 15

Answer:
The solution to the equation is 40
This indicates the max number of wedding invitations they can afford to send within their budget.
Step-by-step explanation:
To find the zero of the function, we set the dependent variable (here, m) to zero.
So we have;
0 = 50-1.25w
1.25w = 50
w = 50/1.25
w = 40
What implication does this have in this context?
Essentially, it means that the couple can send out invitations to a total of 40 people based on their budget.
Answer:
The formula representing the penny's height as a function of time is:
After 7 seconds, the height of the penny will reach 667 feet.
Step-by-step explanation:
The penny experiences free fall.
With an initial velocity of zero and an initial height of h(0)=1,451.
Gravity acts as the acceleration, measured as g=32 ft/s^2.
The model can be initiated by analyzing speed:
Then, the height is expressed as:
The height of the penny at approximately 7 seconds can be calculated as:
After 7 seconds, the penny will stand at a height of 667 feet.
Answer:
Step-by-step explanation:
34+23F=175
23F=175-34=141
F=141/23≈6.13
therefore, he will purchase an additional 7 bags
