blank plus 1/5 equals to 1/2

Answer: 3/10

Step-by-step explanation:

To get the value for the blank, treat it as a variable. Let’s say this blank is x.

x + 1/5 = 1/2

Subtract 1/5 from both sides:

x = 1/2 – 1/5

x = 3/10

The blank is 3/10.

Hope this helps!

Regina rolls a fair, six-sided die every week, and her allowance for that week is twice the

number she rolls on the die. Write an expression to represent Regina's allowance for the

week where n represents the number that Regina rolls on the die that week.

Write your answer in the box.

**Answer:**

6*2=n

**Step-by-step explanation:**

Well, if its a 6 sided die, and she gets twice the amount, then 6*2 and since the total = n 6*2=n The Total of the equation would be 12 instead of n

**Answer:**

7. 4 cm

8. 206 paper cups

9. 175pi cm³

**Step-by-step explanation:**

7. The formula for the volume of a cone can be used.

V = 1/3πr²h

h = 3V/(πr²) = 3(48π cm³)/(π(6 cm)²) = 144/36 cm = 4 cm

**The height of the cone is 4 cm**.

__

8. The volume of the cone with the given dimensions is ...

V = 1/3π(4 cm)²(11 cm) = 176/3π cm³ ≈ 184.307 cm³

The number of times this volume can be filled by 10 gallons is ...

(10 gal)(3785 cm³/gal)/(184.307 cm³/cup) = 205.3 cups

**206 paper cups are needed**.

__

9. We know from the formula for the volume of a cone that it has the same volume as a cylinder 1/3 its height. The composite figure is equivalent to a cylinder with a height of ...

3 cm +(12 cm)/3 = 7 cm

Then the volume is ...

V = πr²h

V = π(5 cm)²(7 cm) = **175π cm³**

__

For this, we recognize that the triangle with sides h, 5, and 13 will be a 5-12-13 right triangle, so the height of the conical part of the figure is h=12 cm. If you haven't remembered that Pythagorean triple, you can find the height from the Pythagorean theorem:

h² +5² = 13²

h = √(169 -25) = √144 = 12

Historical evidence indicates that times between fatal accidents on scheduled American domestic passenger flights have an approximately exponential distribution. Assume that the mean time between accidents is 43 days. What is the variance of the times between accidents

**Answer:**

The variance of the times between accidents is of 1849 days squared.

**Step-by-step explanation:**

**Exponential distribution:**

The exponential probability distribution, with mean m, is described by the following equation:

[tex]f(x) = \mu e^{-\mu x}[/tex]

In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.

The variance of the exponential distribution is:

[tex]Var = \frac{1}{\mu^2}[/tex]

**Assume that the mean time between accidents is 43 days.**

This means that [tex]m = 43, \mu = \frac{1}{43}[/tex]

**What is the variance of the times between accidents?**

[tex]Var = \frac{1}{(\frac{1}{43})^2} = 43^2 = 1849[/tex]

The variance of the times between accidents is of 1849 days squared.

- Fritz worked a total of 22 hours

per week at two jobs. He worked

12 hours per week at one job.

Which equation can be used to

find h, the number of hours Fritz

worked per week at his other job?

A 22-h=12

B 12 +22=h

C 22 + h = 12

Dh - 22 = 12

The answer is A because you initially start of working 22 hours and H is the number of hours worked at the other job which means if you subtract the hours worked between two jobs and the ones you already worked it gives you 10 hours at the other job.Hope this helps!

A circle with a radius of 1 in. is inscribed in a right triangle with legs of 3 in. and 4 in. If a point is randomly chosen within the triangle, what is the probability that the point is NOT also in the circle?

Answer:

Explanation:

Circle Area:

CA = 1²×π

CA ≈ **π in²**

Triangle Area:

TA = 3×4/2 = **6 in²**

Probability:

**P(point not in circle) = (6-π)/6 **≈ 0.48 ≈ 47.64%

The Cosmic Pool company is building a pool in Mary’s back yard. The pool is to be 8ft longer than it is wide and cover 240 square feet of the back yard. Determine both dimensions of the pool and the perimeter.

Group of answer choices

A. Dimensions: width = 20ft & length = 12ft

Perimeter: 32ft

B. Dimensions: width = 20ft & length = 12ft

Perimeter: 64ft

C. Dimensions: width = 12ft & length = 20ft

Perimeter: 64ft

D. Dimensions: width = 12ft & length = 20ft

Perimeter: 32ft

**Answer:**

The correct answer is C.

**Step-by-step explanation:**

Since the Cosmic Pool company's pool's length is 8ft longer than the width, you can immediately rule out choices A and B, since their *widths* are greater than their *lengths* by 8, and not vice versa. This leaves choices C and D. The perimeter of a quadrilateral's formula is [tex]2(l+w)[/tex], which means the length plus the width and multiplied by 2. Using this formula, you can infer that the perimeter is [tex]2(20+12)[/tex] = [tex]2*32[/tex] = 64ft, so choice C is the correct answer.
