Answer:
40°
Step-by-step explanation:
e = 20°
d = 20°
c = 140°
b = 40°
Answer : C) 12.8 cubic cm
The volume ( v) of a gas in a container at a constant temperature varies inversely as the pressure (p)
If y is inversely proportional to x then 
where k is constant of proportionality
v is inversely proportional to p then 
the volume of a gas is 24 cubic centimeters when the pressure is 16 pounds
Given : v= 24 and p = 16. We need to find out k

Multiply by 16 on both sides
k = 384
Now we find out the volume under a pressure of 30 pounds

= 12.8 cubic cm
Y + 7 = -4(x - 2)
The equation for point slope form is
y - y1 = m(x - x1) where m represents the slope.
It coordinates and slope are given, they just need to be plugged into the equation.
y - (-7) = -4(x - 2)
Subtracting a negative can be written as adding a positive, so the equation can be simplified as:
y + 7 = -4(x - 2)
Answer:
D= -9,-6
Im sorry im tryin but its takin a long time
Step-by-step explanation:
Looks like the expression is
(2⁸ • 5⁻⁵ • 19⁰) • (5⁻² / 2³)⁴ • 2²⁸
First, any positive number raised to 0 is 1:
(2⁸ • 5⁻⁵ • 1) • (5⁻² / 2³)⁴ • 2²⁸
(2⁸ • 5⁻⁵) • (5⁻² / 2³)⁴ • 2²⁸
Exponents in a denominator can be rewritten as negative exponents in the numerator:
(2⁸ • 5⁻⁵) • (5⁻² • 2⁻³)⁴ • 2²⁸
Distribute the 4th power across the product 5⁻² • 2⁻³ :
(5⁻² • 2⁻³)⁴ = 5⁻⁸ • 2⁻¹²
so we have
(2⁸ • 5⁻⁵) • (5⁻⁸ • 2⁻¹²) • 2²⁸
Multiplication is associative, so we can ignore the parentheses. Combine factors with equal bases and simplify the exponents:
2⁸ • 5⁻⁵ • 5⁻⁸ • 2⁻¹² • 2²⁸
2⁸⁻¹²⁺²⁸ • 5⁻⁵⁻⁸
2²⁴ • 5⁻¹³
Rewrite the negative exponent as a positive one:
2²⁴ / 5¹³
