Answer:

600 minutes           ( 10 hours)

Step-by-step explanation:

   rate c = 1 job/30 min

   rate r = 1 job/40 mi  

     1 job / ( 1/30 + 1/40) =    1 / ( 7/120) = 17.14 minutes   per ruckload

17.14 * 35 trucks = 600 minutes

Using the normal distribution, it is found that there are 68 students with scores between 72 and 82.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given, respectively, by:

[tex]\mu = 72, \sigma = 10[/tex]

The proportion of students with scores between 72 and 82 is the p-value of Z when X = 82 subtracted by the p-value of Z when X = 72.

X = 82:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{82 - 72}{10}[/tex]

Z = 1

Z = 1 has a p-value of 0.84.

X = 72:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{72 - 72}{10}[/tex]

Z = 0

Z = 0 has a p-value of 0.5.

0.84 - 0.5 = 0.34.

Out of 200 students, the number is given by:

0.34 x 200 = 68 students with scores between 72 and 82.

5/7    11/17 = 0.65

5/10

Step-by-step explanation:

In this article, I will show you how to find the area of a circle and express your answer in terms of pi (π). First, you'll need to familiarize yourself with the formula for calculating the area of a circle:

A = π * r²

Let's define our variables:

A: area of the circle

π: pi (a mathematical constant that is approximately equal to 3.141492 . . .)

r: radius of the circle (the distance from the circle's center point to its edge)

Typically, to find the area of a circle, we would simply plug in the circle's radius for r and 3.141592 for π. If so, our answer would be a number.

Therefore, the answer is 16π.

Answer:

Answer:

change 0.3 to fraction which is 3/10 then substract from 1

then it will be 1-3/10 =7/10 also 0.7

Answer:

centre = ( -6 , 4 ) and radius = 6

Step-by-step explanation:

(x-a)² + (y-b)² = r²

where (a , b ) represents the centre and r the radius.

compare the standard form to (x+6)² + (y−4)² = 36

=> a = -6, b=4 and r = [tex]\sqrt{36}[/tex] = 6

=> centre = (-6, 4) and radius = 6

Answer:

44

Step-by-step explanation:

base(b) = 11, height(h) = 8, Area of parallelogram = ? We know that, Area of parallelogram = 1/2 × b× h = 1/2 × 11 × 8 = 11 × 4 = 44 square units

The answer is 88


11x8 = 88 base times height !!!!

Answer:

Take the base of the parallelogram to be 40 cm. 1,200 sine (36) = 40 * h. Divide both sides by 40. So, the height of the parallelogram is 17.63 cm.

Step-by-step explanation:

That is kind of hard. I have used the internet to help create that repeating decimal to a fraction and got that as your answer.

Answer:

19/33

Step-by-step explanation:

There are two repeating decimals so divide 57 (repeating part)... by 100x minus x

57/100x -x

57/100x - x = 0

100x - x = 57

99x=57

x=57/99

Answer:

[tex]\frac{1}{2}[/tex]

Find the least common factors of both numbers.

[tex]1/3~has~4\\2/12~has~1[/tex]

Multiply the numerator and denominator.

[tex]\frac{1 * 4}{3 * 4} = \frac{4}{12} \\\\\frac{2 * 1}{12 * 1} = \frac{2}{12}[/tex]

Add both numbers together. That does not mean you have to add the denominators. When the denominators are the same, keep them the same.

[tex]\frac{4}{12} +\frac{2}{12} = \frac{6}{12}[/tex]

Simplify.

[tex]\frac{6}{12} -- > \frac{1}{2}[/tex] because they are both halves.

Part I: Determining the common denominator of the terms

Given expression:

[tex]\dfrac{1}{3} + \dfrac{2}{12}[/tex]

To simplify the expression, we need to determine the common denominator of both fractions (1/3 and 2/12). To determine the common denominator of both fractions, we need to determine the LCM of the denominators (12 and 3). Simply write the multiples of (12 and 3) and determine the least common multiple (LCM).

Since the LCM is 12, our common denominator is 12.

Part II: Multiplying both denominators by a number which is equivalent to 12

Now, multiply both denominators by a number such that the denominators are equivalent to 12. Keep in mind that the number you multiply the denominator should also be multiplied to the numerator.

[tex]\implies \dfrac{x}{3x} + \dfrac{2y}{12y} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \huge\text{[}3x = 12; 12y = 12\huge\text{]}[/tex]

[tex]\implies \dfrac{4}{3(4)} + \dfrac{2(1)}{12(1)} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \huge\text{[}x = \dfrac{12}{3} = 4; y = \dfrac{12}{12} = 1 \huge\text{]}[/tex]

[tex]\implies \dfrac{4}{12} + \dfrac{2}{12}[/tex]

Part III: Adding the fractions

Since the denominators are the same, we can now add the fractions;

[tex]\implies \dfrac{6}{12}[/tex]

Part IV: Simplifying the fraction obtained from the above

Since 6 is divisible by 12, we can further simplify the fraction.

[tex]\implies \dfrac{6 \times 1}{6 \times 2}[/tex]

[tex]\implies \boxed{\dfrac{1}{2}}[/tex]
