Step-by-step explanation:

Answer:

27/125

Step-by-step explanation:

Given the decimal value 0.216, we are to express as a fraction in the fofrm of p/q

0.216 = 216/1000

216/1000 = 2 * 108/2 * 500

216/1000 = 108/500

108/500 = 4*27/4*125

108/500 = 27/125

Hence the expression in form p by q is 27/125

Answer:

order of operations matter here so

72 - 4 × 12 ÷ 6

start with 4 × 12 (which equals 48)

72 - 48 ÷ 6

next is 48 ÷ 6. (which equals 8)

72 - 8 = 64

so g is correct

Answer:

Surface area: 250

Volume: 1375

Step-by-step explanation:

Scale factor: 4:5

This means that the dimensions of the larger figure are 5/4 of those in the smaller figure.

Surface area:

The surface area is found multiplying the square of the change(5/4) by the original surface area(160). So

[tex]S = (\frac{5}{4})^2 \times 160 = \frac{25}{16} \times 160 = 25 \times 10 = 250[/tex]

Volume:

The volume is found multiplying the cube of the change(5/4) by the original volume(704). So

[tex]S = (\frac{5}{4})^3 \times 704 = \frac{125}{64} \times 704 = 125 \times 11 = 1375[/tex]

Answer:

The 90% confidence interval for the mean score of all takers of this test is between 59.92 and 64.08. The lower end is 59.92, and the upper end is 64.08.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1-0.9}{2} = 0.05[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].

So it is z with a pvalue of [tex]1-0.05 = 0.95[/tex], so [tex]z = 1.645[/tex]

Now, find the margin of error M as such

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.645*\frac{4}{\sqrt{10}} = 2.08[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 62 - 2.08 = 59.92

The upper end of the interval is the sample mean added to M. So it is 62 + 2.08 = 64.08.

The 90% confidence interval for the mean score of all takers of this test is between 59.92 and 64.08. The lower end is 59.92, and the upper end is 64.08.

Answer:

Question 15: x = 17

Question 16: area = 5610 units

Step-by-step explanation:

Question 15:

The perimeter is the sum of all sides of a triangle.

It is given that the perimeter is 374 units.

[tex]p = 8x - 4 + 9x + 4 + 4x + 17[/tex]

[tex]374 = 8x - 4 + 9x + 4 + 4x + 17[/tex]

Add all the like terms.

[tex]374 = 21x + 17[/tex]

Subtract 17 from both sides.

[tex]357 = 21x[/tex]

Divide by 21 from both sides.

[tex]17 = x[/tex]

Question 16:

The area of a triangle can be found by using the following formula:

[tex]a = \frac{1}{2} bh[/tex]

(where a is the area, b is the base, and h is the height)

Using the value of x you just found previously (17), you can calculate the base and height by substituting 17 with x in their respective equations.

[tex]h = 8x - 4[/tex]

[tex]h = 8(17) - 4[/tex]

[tex]h = 134[/tex]

[tex]b = 4x + 17[/tex]

[tex]b = 4(17) + 17[/tex]

[tex]b = 85[/tex]

Now that you found the base and height, substitute the values, 134 and 75, into the area of a triangle formula.

[tex]a = \frac{1}{2} bh[/tex]

[tex]a = \frac{1}{2} (85)(132)[/tex]

[tex]a = 5610[/tex]

she would be under $13

Step-by-step explanation:

1.50+1= 2.50+9.28= 11.78 leaving her with a remaining balance off $1.22

Answer:

c=36p+36

Step-by-step explanation:

Okay so the cost of the meal without tip is $36. To find the tip, we would multiply p by 36. To find our total (c), we would add this (36p) to the original 36.

In other words:

c=36p+36

(can also be written as c=36(1+p) )

Step-by-step explanation:

2x-6 = -2 Add 6 to both sides

2x = -2 + -6

2x = -8 Divide both sides by 2

x = -8/2

The number of chair covers Diane will be able to make is 5.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Length of the fabric = 20 yards

Length of fabric needed for each chair cover = 3(2/5) yards

The number of chair covers that can be made with 20 yards.

= 20 ÷ 3(2/5)

= 20 ÷ 17/5

= 20 x 5/17

= 100/17

=  5.8

= 5

Thus,

The number of chair covers is 5.

Answer:

[tex]CSA = 660cm^2[/tex] --- Curved Surface Area

[tex]TSA = 968cm^2[/tex]  --- Total Surface Area

Step-by-step explanation:

Given

Shape: Cylinder

[tex]h = 15[/tex] -- height

[tex]r = 7[/tex] --- radius

Solving (a): The curved surface area (CSA)

This is calculated as:

[tex]CSA = 2\pi rh[/tex]

This gives:

[tex]CSA = 2 * \frac{22}{7} * 7 * 15[/tex]

[tex]CSA = 2 * 22* 15[/tex]

[tex]CSA = 660cm^2[/tex]

Solving (b): The total surface area (TSA)

This is calculated as:

[tex]TSA = 2\pi r(h + r)[/tex]

This gives:

[tex]TSA = 2 * \frac{22}{7} * 7 * (15 + 7)[/tex]

[tex]TSA = 2 * 22 * (15 + 7)[/tex]

[tex]TSA = 2 * 22 * 22[/tex]

Answer:

y = x-4

Step-by-step explanation:

y = -x-5

Slope of line is -1.

Slope of perpendicular to line is 1.

Point-slope equation for line of slope 1 that passes through (6,2):

y-2 = 1(x-6)

Rearrange equation to slope-intercept form:

y = 1(x-6) + 2

y = x-4
