The number of kilograms, y, of original oxygen that remain in the body after t hours can be modeled by the equation y = 0.32(0.76)t . What is the rate of decrease of original oxygen?
Answer:
24%
Step-by-step explanation:
The number of kilograms, y, of original oxygen that remain in the body after t hours can be modeled by the equation y = 0.32(0.76)^t . What is the rate of decrease of original oxygen?
The formula for Exponential Decrease is given as:
y = a(1 - r)^t
Where
y = Amount after time t
a = Original amount
r = Rate of decrease
t = Time
Comparing both Equations
y = 0.32(0.76)^t = y = a(1 - r)^t
We know that
0.76 = 1 - r
Solving for r
Collect like terms
r = 1 - 0.76
r = 0.24
Converting to Percentage
= 0.24 × 100
= 24%
Therefore, the rate of decrease of original oxygen is 24%

How many males represented in the Venn diagram below have brown hair or brown eyes?
A diagram contains a rectangle labeled 100 males. The rectangle contains two overlapping ovals. The left oval is labeled brown hair 34, and the right oval is labeled brown eyes 22. The overlapping region is labeled 18. Both ovals are shaded.
74
22
56
34
Answer:
I got this answer right its 56
Step-by-step explanation:
I got this question right
Interpreting the Venn diagram given, the number of males with brown eyes or brown hair can be deduced to be 74
Number with brown hairs = 34 Number with brown eyes = 22Number with both brown hairs and eyes = 18Number with brown eyes or brown hairs :
Brown eyes + Brown hairs + Both brown hairs and brown eyes
(34 + 22 + 18) = 74
Therefore, 74 males have brown eyes or brown hairs

Answer:
m(arc)RST = 154 deg
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
x + 77 + x + 103 = 180
2x + 180 = 180
2x = 0
x = 0
m<RST = x + 77 = 0 + 77 = 77
The measure of an inscribed angle is half the measure of its subtended arc.
m<RST = (1/2)m(arc)RST
77 = (1/2)m(arc)RST
154 = m(arc)RST
m(arc)RST = 154 deg

Using the area formula, the height of the cylinder is found to be approximately 7.87 inches.
What is area?
An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.
Use the formula for the volume of a cylinder to relate the radius, height, and volume of the cylinder -
V = πr²h
Where V is the volume, r is the radius, and h is the height of the cylinder.
It is given that the area of the base of the cylinder is 150 square inches.
Since the base of a cylinder is a circle, the area of the base is given by -
A = πr²
Where A is the area of the base and r is the radius.
Solving for r -
r² = A/π = 150/π
Use the given volume and radius to solve for the height -
V = πr²h
1050 = π(150/π)²h
h ≈ 7.87 inches
Therefore, the height is 7.87 inches.
