Which fraction is equivalent to 1/8

Answer:

b ≈ 13.80 in

Step-by-step explanation:

Since the triangle is right use the tangent ratio to solve for b

tan17.71° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{AC}{43.21}[/tex]

Multiply both sides by 43.21

43.21 × tan17.71° = AC, hence

AC = b ≈ 13.80 ( to 2 dec. places )

The solution to the quadratic equation -2x² - 16x - 44 = 0 are [tex]x = -4 -4\sqrt{6}i \ and \ x = -4 +4\sqrt{6}i[/tex]

Given the quadratic equation in the question:

-2x² - 16x - 44 = 0

To solve the quadratic equation -2x² - 16x - 44 = 0, we use the quadratic formula:

[tex]x = \frac{-b\±\sqrt{b^2 - 4ac} }{2a}[/tex]

From the equation:

a = -2, b = 16, c = -44

Plug these values into the above:

[tex]x = \frac{-b\±\sqrt{b^2 - 4ac} }{2a} \\\\x = \frac{-(-16)\±\sqrt{(-16)^2 - 4(-2)(-44)} }{2(-2)} \\\\x = \frac{16\±\sqrt{256 - 352} }{-4} \\\\x = \frac{16\±\sqrt{-96} }{-4} \\\\x = \frac{16\±4\sqrt{6}i }{-4} \\\\x = -4 \±4\sqrt{6}i\\\\x = -4 -4\sqrt{6}i \ or \ x = -4 +4\sqrt{6}i[/tex]

Therefore, the values of x are [tex]x = -4 -4\sqrt{6}i \ and \ x = -4 +4\sqrt{6}i[/tex]

Answer:  4

Step-by-step explanation:

Inversely proportional means xy = k, where k is the constant of proportionality

First, find k when x = 2 and y = 400 ----> 2(400) = k   --> 800 = k

Then, find y when x = 200 (knowing that k = 800)

                                    200y = 800

                                           y = 4

Final answer:

The ratio of boys to girls in Mrs. Fronko's class in simplest form is 3:4, obtained by dividing both sides of the given ratio, 6:8, by the greatest common divisor, which is 2.

Explanation:

To find the ratio of boys to girls in Mrs. Fronko's class in its simplest form, we will start with the ratio given, which is 6 boys for every 8 girls. This can be written as 6:8. To simplify ratios, we divide both sides of the ratio by the greatest common divisor. In this case, the greatest common divisor of 6 and 8 is 2. Therefore, we divide both numbers by 2 to find the simplest form of the ratio.

6 ÷ 2 = 3 and 8 ÷ 2 = 4.

After dividing both numbers by 2, the ratio becomes 3:4. This indicates that for every 3 boys, there are 4 girls in Mrs. Fronko's class, and this is the simplest form of the ratio.

Answer:

Amount of sales = rs 10,000.

Step-by-step explanation:

He earns 2000 - 1000 =  rs 1000 from sales.

This  equals 10% ( = 0.10 as a fraction) of his sales so his sales must have been  1000 / 0.10

= rs 10,000.

Answer:

17140

Step-by-step explanation:

The number in the tenths place is 5 or higher so you need to round it up to 17140.

Answer:

17140

Step-by-step explanation:

If the number in the tenths place is 5 or more, round the number up.

Juice bottles are J, replace j with 6 in the equation and solve for w:

3w + 4(6) = 39

3w + 24 =39

Subtract 24 from both sides:

3w = 15

Divide both sides by 3:

w = 15/3

w = 5

You can buy 5 water bottles.

Answer:

5

Step-by-step explanation:

The number of water bottles [tex]= w[/tex]

The number of juice bottles [tex]= j[/tex]

We have, [tex]3w + 4j = 39[/tex]

When we purchase 6 bottles of juice, [tex]j = 6[/tex]

So,

[tex]3w + 4j = 39[/tex]

[tex]3w + 4 \times 6 = 39[/tex]

[tex]3w + 24 = 39[/tex]

[tex]3w = 39 - 24[/tex]

[tex]3w = 15[/tex]

[tex]w = \frac{15}{3}[/tex]

[tex]w = 5[/tex]

Therefore, we can buy 5 bottles of water.

Answer:

The value in the table that makes the quantities proportional to one another is y = 3

Step-by-step explanation:

Two quantities x and y  are proportional one to another if they can be expressed  as

y = kx

where k is the constant of proportionality. We can find k using an specific point. Take the first one

y = kx

k=  y/x  with (3.1 )

k= 1/3

So

y =1/3x for this case

If the two quantities are proportional, this rule must be true for any point (x,y) . Lets prove it

Point 2 (6,2)

2 =1/3*(6)

2= 2 True

Point 4 (12,4)

4 =1/3*(12)

4= 4 True

So to accomplish the rule in point 3, and finally in all table we must have that

y =1/3x is true  for Point 3 (9,y) Then

y = 1/3 (9) = 9/3 = 3

y= 3

Y must be 3

Final answer:

The slope of the line represented by the equation 12x - 8y + 7 = 9 is 3/2. To find this, the equation was rearranged into slope-intercept form, revealing the slope as the coefficient of x.

Explanation:

To find the slope of the line with the given equation 12x - 8y + 7 = 9, you first need to rearrange the equation into slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept.

First, subtract 12x from both sides of the equation to isolate terms with y on one side:

-8y = -12x + 2

Next, divide each term by -8 to solve for y:

y = (12/8)x - 2/8

Simplify the fractions:

y = (3/2)x - 1/4

Now the equation is in slope-intercept form, and you can see that the slope m is 3/2 or 1.5. Therefore, the slope of the line is 3/2.

Answer:

It's C. If you divide them you get 1.25 for both of them and its proportional

0.000006 is 300 times greater than 0.00000002.

To find out how many times greater 0.000006 is than 0.00000002,

We need to divide 0.000006 by 0.00000002.

So, let's perform the calculation:

0.000006 ÷ 0.00000002 = 300

This means that 0.000006 is 300 times greater than 0.00000002.
