Answer: The area is 221.558, with the explanation below.

Step-by-step explanation: The area of a circle is solved by the equation

π x r². You are given the diameter of 16.8, and the radius is half of it, so the radius = 16.8/2 = 8.4

Next, you need to plug your numbers into the equation:

Area = 3.14 x 8.4²

Area = 3.14 x 70.56

Area = 221.558

Answer:

The probability that a student is proficient in mathematics, but not in reading is, 0.10.

The probability that a student is proficient in reading, but not in mathematics is, 0.17

Step-by-step explanation:

Let's define the events:

L: The student is proficient in reading

M: The student is proficient in math

The probabilities are given by:

$P (L) = 0.81\\P (M) = 0.74\\P (L\bigcap M) = 0.64$

$P (M\bigcap L^c) = P (M) - P (M\bigcap L) = 0.74 - 0.64 = 0.1\\P (M^c\bigcap L) = P (L) - P (M\bigcap L) = 0.81 - 0.64 = 0.17$

The probability that a student is proficient in mathematics, but not in reading is, 0.10.

The probability that a student is proficient in reading, but not in mathematics is, 0.17

The formula for converting degrees Fahrenheit (F) to degrees Kelvin (K) is:

drek231 [11]

K = F + 459.67

Subtract K on both sides:

0 = F - K + 459.67

Subtract F on both sides:

-F = -K + 459.67

Divide each term by -1 so that the variables are positive:

F = K - 459.67

Answer:

162 inches.

Step-by-step explanation:

Please consider the complete question.

Carlos is helping his grandmother make a rug. They have 5 yards of fabric, which is equal to 180 inches. They need an additional of 4 1/2 yards of fabric to finish the trim. How many inches are in $4\frac{1}{2}$ yards?

Let us convert $4\frac{1}{2}$ into improper fraction as:

$4\frac{1}{2}=\frac{4\cdot 2+1}{2}=\frac{8+1}{2}=\frac{9}{2}$

Now, we will use proportions to solve our given problem as:

$\frac{\text{Inches}}{\text{Yard}}=\frac{180}{5}$

$\frac{\text{Inches}}{\text{Yard}}=36$

$1\text{ Yard}=36\text{ Inches}$

To find number of inches in 9/2 yards, we will multiply 9/2 by 36 as:

$\frac{9}{2}\text{ Yards}=\frac{9}{2}\times 36\text{ Inches}$

$\frac{9}{2}\text{ Yards}=9\times 18\text{ Inches}$

$\frac{9}{2}\text{ Yards}=162\text{ Inches}$

Therefore, there are 162 inches in $4\frac{1}{2}$ yards.

Answer:

55.2° ≤ c ≤ 55.8°

Step-by-step explanation:

We know a + b + c = 180

Let's take the smallest value of a and b and find largest value of c:

51.3 + 72.9 + c = 180

c = 55.8

Now,

Let's take the largest value of a and b and find smallest value of c:

51.5 + 73.3 + c = 180

c = 55.2

Thus, we can say, range of c is:

55.2° ≤ c ≤ 55.8°
