Answer:

  3. 4 N

  4. 3√2 N

Step-by-step explanation:

Again, these are "special triangles," so you already know the ratios of the side lengths.

3. The given sides have the ratio 2 : 3.464 = 1 : 1.732 = 1 : √3, so the remaining side finishes the special triangle ratios 1 : √3 : 2 = 2 : 3.464 : 4.

  T = 4 N

__

4. The given sides have the ratio 3 : 3 = 1 : 1, so the remaining side finishes the special triangle ratios 1 : 1 : √2 = 3 : 3 : 3√2.

  T = 3√2 N

Answer:

$3.86

Step-by-step explanation:

When finding averages, this can also be known as the mean value. How we find this is by adding all the money values together first, which is $18 + $23 + $13 = $54. Then we add the number of all the employees, which is 6 + 2 x 4 or 8 which is 14 employees. Then we divided the amount of money amongst all of the employees, so 54/14 = 3.85714286 approximately. Of course those extra exact numbers are irrational and won't work in money, so to round to the nearest tenth, we go to the tenths place which is the 5 in $3.85, and the next number is 7 after that. The rule for rounding is if the number after the number you're rounding to is 5 or higher, you should increase it by one, but if not, like if it's 4 or less, it remains the same. In this particular case, since 7 is higher than 5, we would round $3.85 to $3.86 instead. This represents the average pay.

Step-by-step explanation:

Answer:

27/40

Step-by-step explanation:

The percentage 67.5% as a fraction in simplest form is 16.875/25.

To convert 67.5% to a fraction in simplest form, we divide the percentage by 100 and simplify if possible.

67.5% can be expressed as 67.5/100.

To simplify the fraction, we divide both the numerator and denominator by their greatest common divisor (GCD), which is 2:

67.5/100 = (67.5 ÷ 2) / (100 ÷ 2)

= 33.75/50

We can simplify this fraction further by dividing both the numerator and denominator by their GCD, which is 2:

33.75/50 = (33.75 ÷ 2) / (50 ÷ 2)

= 16.875/25

Since there is no common factor other than 1 between the numerator and denominator, the fraction 16.875/25 is already in its simplest form.

Answer:

Step-by-step explanation:

Given the roots of quadratic equation to be 5 and 2/3, the two factors are x-5 and x-2/3.

The variable in question are both subtracted from the root given to get the actor of the quadratic equation or polynomial. We can get the resulting quadratic function by multiplying both factors together as shown;

(x-5)(x-2/3)

= x²- 2x/3 -5x +10/3

= x²-(2x-15x)/3+10/3

= x²-17x/3 +10/3

Multiply through by 3

= 3x²-17x +10 = 0

The resulting quadratic equation for both factors will be  3x²-17x +10 = 0 and the other factor is x-2/3

Answer:

The answer is "[tex]\bold{ y^{ \frac{2}{3}}} = \frac{2}{3}x + c} \\\\[/tex]"

Step-by-step explanation:

By using the given method we  separate the above-given variable and  find the solution of:

[tex]\bold{\frac{dy}{dx} =y^{\frac{1}{3}}}[/tex]

Solution:

[tex]\to \frac{dy}{dx} =y^{\frac{1}{3}}\\\\\to \frac{dy}{y^{\frac{1}{3}}} =dx\\\\\to y^{ - \frac{1}{3}} dy =dx\\\\[/tex]

Integrate the above value:

[tex]\to \int y^{ - \frac{1}{3}} dy = \int 1 dx\\\\\\\to \frac{y^{ - \frac{1}{3} +1}}{- \frac{1}{3} +1} = x \\\\ \\\to \frac{y^{ \frac{-1 +3}{3}}}{ \frac{-1+3}{3} +1} = x \\\\\\\to \frac{y^{ \frac{2}{3}}}{ \frac{2}{3} +1} = x \\\\\\\to \bold{y^{ \frac{2}{3}}} = \frac{2}{3}x + c} \\\\[/tex]

Answer:

[tex]\sqrt{\frac{S}{4\pi } } =r[/tex]

Step-by-step explanation:

S = 4 pi r^2

Divide each side by 4 pi

S / (4 pi) = 4 pi r^2 / (4 pi)

S / (4 pi) = r^2

Take the square root of each side

sqrt(S / (4 pi)) =sqrt( r^2)

sqrt(S / (4 pi)) =r

[tex]\sqrt{\frac{S}{4\pi } } =r[/tex]

Answer:

cherry street is 85 yards, while orange dr. and peach ave. is 113 yards, meaning that cherry st. is 28 yards faster

Step-by-step explanation:

(85 x 85) - (77 - 77) = 1296

square root of 1296 is 36

77 + 36 = 113

113 - 85 = 28

this means that cherry st. is 28 yds faster

using the Pythagorean Theorum

The distance that Layne would have to travel further if he took the given paths is required.

If Layne took Orange Drive and Peach Avenue instead his trip would be 28 yards longer.

c = Length of Cherry st. = 85 yards

a = Length of Orange dr.

b = Length of Peach av. = 77 yards

The angle between orange drive and peach avenue has been assumed to be [tex]90^{\circ}[/tex].

We need to find the sum of the distances of the paths orange drive and peach avenue.

So, we need to find the length of orange drive.

Applying the Pythagoras theorem

[tex]a^2+b^2=c^2\\\Rightarrow a=\sqrt{c^2-b^2}\\\Rightarrow a=\sqrt{85^2-77^2}\\\Rightarrow a=36\ \text{yards}[/tex]

The distance traveled when orange drive and peach avenue is taken is

[tex]36+77=113\ \text{yards}[/tex]

The extra distance traveled

[tex]113-85=28\ \text{yards}[/tex]

Answer:

0.034

Step-by-step explanation:

the opposite of multiplication is division. 0.34 divided by 10 is 0.034. you can also figure this out by moving the decimal to the left once.

0.34 is 10 times greater than 0.034.

A decimal is represented by a dot or a point it separates the whole part and the fractional part of the given number.

According to the given data

0.34 is 10 times as great means we have to divide 0.34 by 10

which is

= (0.34/10)

= 0.034

∴ 0.34 is 10 times greater than 0.034.

We can also do this by simply moving the decimal to one left of the digit.

For example if given a.cb and we have been asked what number is 100 times greater than a.bc we can simply move the decimal to the right by 2 place then it will be abc.

Substitute the answers in the choices for x.

Answer:

Just use long subtraction by expanding the decimal places of the whole number. This is done by adding a point, and enough zeros to it to match the number of decimal digits in the other number (digits after the decimal point).

i.e: 5 - 2.48374827, 2.48374827 has 8 decimal digits, so add 8 zeros after the point.
