Answer:
What are we meant to do?
An airplane's altitude in feet during its descent can be found using the equation y=-150x + 30,500. After new government regulations become law, the descent isnow modeled by the equation y=-150x + 30,000. Which statement describes this change?
The airplane starts its descent from an altitude 500 feet lower.
The airplane descends 500 feet per horizontal mile slower.
The airplane descends 500 feet per horizontal mile faster.
The airplane starts its descent from an altitude of 500 feet.
Answer:
The airplane would starts its descent from an altitude 500 feet lower.
Step-by-step explanation:
The x-axis is horizontal and the y-axis is vertical (altitude). It would be 500 feet lower because they took 500 away from the 30,000.
The sum of two numbers is 24. The second number minus the first number equals 2.
Let x represent the first number. Let y represent the second number.
Write a system of equations to represent the situation.
First sentence: First Equation:
Second Sentence: Second Equation:
*Do not include spaces in your equations.
Part 2: Find the numbers. ( , )
Answer:
(11, 13)
Step-by-step explanation:
First Equation: x+y=24
Second Equation: y=x+2
x + (x + 2) = 24
2x + 2 - 2 = 24 - 2
2x/2 = 22/2
x = 11
y = (11) + 2
y = 13
Therefore, the solution to the system is (11, 13)

12 minutes for 5 songs =
minutes for 20 songs
Answer:
48
Step-by-step explanation:
5 songs would equal 12 minutes, right?
5 times what equals 20? It's 4, so you take 12 times 4 since there'd be 4 times as many songs. So, to listen to 20 songs it'd take 48 minutes.
14 yd
Area Formula= base x height
Base = 7 yd X 2yd Height= 14 yd
Volume = Area of base x height
Answer:
The volume is 196 cubic yards
Step-by-step explanation:
Given
[tex]Base\ Area = 7yd * 2yd[/tex]
[tex]Height = 14yd[/tex]
Required
The volume
The volume is given as:
[tex]Volume = Base\ Area * Height[/tex]
Where:
[tex]Base\ Area = 7yd * 2yd[/tex]
[tex]Height = 14yd[/tex]
So, the equation becomes
[tex]Volume = 7yd * 2yd * 14yd[/tex]
[tex]Volume = 196yd^3[/tex]

Answer:
n = -3
Step-by-step explanation:
11(n – 1) + 35 = 3n
11n - 11 + 35 = 3n

Find the area of the shaded region to the nearest tenth.
Answer:
Shaded region is 18.3 units²
Step-by-step explanation:
First find the area of the white triangle. The base and height of this triangle are both 8. Thus, the area of the triangle is (1/2)(base)(height), or 32 units.
Next, find the area of the whole circle. It is πr², which in this case comes
out to π(8 units)² = 64π units². Realize that (1/4) of this, or 16π units², is the area of the quarter circle that contains the triangle.
To find the shaded area, take the area of the quarter circle (16 π units²) and subtract the area of the triangle (32 units²).
16π units² - 32 units² = 18.3 units²
Shaded region is 18.3 units²

Step-by-step explanation:
[tex]a^{2} +1300^{2} =1700^{2} \\ a^{2} =1700^{2} -1300^{2} \\ =2890000-1690000\\ =1200000[/tex]
[tex]a^{2} =1200000\\ a=\sqrt{1200000} \\ a=1095.4451[/tex]
round to 1,095
Answer:
The answer is 1
Step-by-step explanation:
[tex]a =\sqrt{c^{2} - {b^{2 } \\[/tex]
[tex]a = \sqrt{1700^2 - 1300^2}[/tex]
[tex]a = \sqrt{2890000 - 1690000}[/tex]

Answer:
x = 1
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
1. distribute 7 to x and 5.
42 = 7x + 35
2. subtract 35 on both sides.
7 = 7x
3. Divide by 7 for both sides.
1 = x

Rewrite the equation by completing the square.
f(x)=x^2+x-30
f(x)=_(x+_)^2+_
pls helppppp
Answer:
f(x)= (x-5)(x+6)
Step-by-step explanation:
First, we find the factors of -30 that add up to +1
We can use 6 and -5
6+(-5)=1
f(x)= x^2+6x - 5x-30
then, we do group factorization
f(x)= x(x+6)- 5(x+6)
f(x)= (x-5)(x+6)
