Answer: the answer is 1.6 or 0.6.

Answer:

8⅓

Step-by-step explanation:

divide 5 by (3/5). To divide by a fraction, flip the fraction and multiply. Make the 5 into a fraction by putting a '1' underneath:

(5/1)(5/3) = 5x5/1x3 = 25/3 = 8⅓

You can take 3/5 away from 5, 8⅓times

Answer:

y = - [tex]\frac{3}{2}[/tex]x - [tex]\frac{8}{3}[/tex]

Step-by-step explanation:

2x-3y=8

rewrite, solve for y

3y = 2x - 8

divide by 3

y = [tex]\frac{2}{3}[/tex]x - [tex]\frac{8}{3}[/tex]

perpendicular = negative reciprocal slope = - [tex]\frac{3}{2}[/tex]

Answer:

x>-8 (Or option D)

Step-by-step explanation:

-2x+7<23 Subtract 7 from both sides

-2x<16 Now divide by -2. You also have to flip the < sign because you are dividing by a negative number

x>-8

The reasoning for D over C is because D is an open circle meaning that it is only less than or greater than. When it is a closed circle, it means less than or equal to or greater than or equal to. :)

Answer:

v = 141.76 m/s

Step-by-step explanation:

Given that,

The ball reaches the ground with a velocity of 4.43h m/sec.

We need to find the velocity of the ball at a height of 32 m.

Since, v = 4.43h

Put h = 32 m in the above expression.

v = 4.43(32)

v = 141.76 m/s

So, the velocity of the ball is equal to 141.76 m/s.

Answer:

25%

Step-by-step explanation:

Since we know that the markdown is $20 by subtracting 80-60 , we find out what percent of 20 is 80. To do that you do 20/80, which is 0.25, or 25 percent.

Answer:

x = 113

Step-by-step explanation:

Since the shape is a quadrilateral, the angles add up to 360 so:

x + 87 + 113 + 47 = 360

x + 247 = 360

x = 360 - 247

x = 113

Answer: [tex]1200 m[/tex]

[tex]75\ m/min[/tex]

Step-by-step explanation:

Given

Alex Jogged 3 rounds of 400 m track

It took 16 min to Jog 3 rounds

(a) Total distance Alex had Jogged

[tex]\Rightarrow 3\times 400=1200\ m[/tex]

(b) Average speed is the total distance by the total time

[tex]\Rightarrow \dfrac{1200}{16}=75\ m/min[/tex]

Answer:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year.

Solving our equation:

A = 25800(1 + (0.04 × 10)) = 36120

A = $36,120.00

The total amount accrued, principal plus interest, from simple interest on a principal of $25,800.00 at a rate of 4% per year for 10 years is $36,120.00.

Answer:

ans is (D)500/3 π unit^3

Explanation :

Formula for volume of sphere is 4/3 π r^3 .

The volume of the sphere below is 500π/3 units³, the correct option is D.

If the given sphere is of radius r units, then its volume is given as:

[tex]V= \dfrac{4}{3} \pi r^3 \: \rm unit^3[/tex]

Suppose that radius of the considered sphere is of 'r' units.

Then, its surface area S would be:

[tex]S = 4\pi r^2 \: \rm unit^2[/tex]

We are given that;

The radius = 5

Now,

The volume of a sphere is given by the formula V = ⁴⁄₃πr³, where r is the radius of the sphere1. To find the volume of a sphere whose radius is 5 units, you need to plug in r = 5 into the formula and simplify it using arithmetic operations.

V = ⁴⁄₃πr³

V = ⁴⁄₃π(5)³

V = ⁴⁄₃π(125)

V = (4)(125)π/3

V = 500π/3

Therefore, by the volume of sphere formula the answer will be V = 500π/3 units³.

Answer:

The 85% confidence interval for the mean number of dresses purchased each year is (6.1, 6.3).

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 - 0.85}{2} = 0.075[/tex]

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

That is z with a pvalue of [tex]1 - 0.075 = 0.925[/tex], so Z = 1.44.

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 = 1.44\frac{1.1}{\sqrt{208}} = 0.1[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 6.2 - 0.1 = 6.1

The upper end of the interval is the sample mean added to M. So it is 6.2 + 0.1 = 6.3

The 85% confidence interval for the mean number of dresses purchased each year is (6.1, 6.3).

Answer:

a) t= 2hours and 10 minutes

b) t=4hours and 20 minutes

v1t1=v2t2

Answer:

Step-by-step explanation:

rate = distance / time     distance is constant (a-b) so call it D

time = distance / rate      rate = speed (ie miles per hour = mph)

time = distance / speed      

A)  if the new speed is 1.5 of the original speed    

     original time = 3.25 hours  or 195 minutes

  3.25  = D / 1       new time = D/1.5       find new time

         3.25 is to D   as    new time is to  D/1.5

            3.25/D = new time / D/1.5                   multiple D/1.5 on both sides

            (3.25/D) ( D/1.5)      = new time           the distance D cancels

            3.25 (D / D) / 1.5   = new time

            3.25 / 1.5  = 2.167 hours   or 2 hours and 10 minutes

B)   if the speed is 3/4 the original speed

original time = 3.25 hours  or 195 minutes

  3.25  = D / 1       new time = D/(3/4)       find new time

         3.25 is to D   as    new time is to  D/0.75

            3.25/D = new time / D/0.75                       multiple D/0.75 on both sides

            (3.25/D) ( D/0.75)      = new time

            3.25 (D / D) / 0.75     = new time

            3.25 / 0.75  = 4.333 hours   or 4 hours and 20 minutes

Answer:

1.6 m = 5.3 ft

Answer:

Part A: so the GCF is 3y, 

We need to rewrite the equation such as: 

-36 as -12 · 3, -9 as -3 · 3, 12 as 4 · 3

It will look like this: 

3x^3 y +4 · 3xy + 3 · 3x^2 y + 4 · 3 · 3y

We then need to factor out 3y:

3y(x^3 + 4x - 3x^2 - 12)

Part b: factor out completely

3y(x^3 + 4x - 3x^2 - 12)

So, we need to do the following:

3y{x^2(x-3) + 4 (x-3)}

we then get the final factor: 3y(x - 3) (x^2 + 4)

Step-by-step explanation:

The factored expression is:

[tex]3y(x^3 + 4x - 3x^2 - 12)[/tex]

------------------------

To factor the expression:

------------------------

The expression is:

[tex]3x^3y + 12xy - 9x^2y - 36y[/tex]

------------------------

The numeric coefficients are: 3, 12, 9, 36

The gcf of the numeric coefficients is:

3 - 12 - 9 - 36|3

1 - 4 - 3 - 12

The gcf of the numeric coefficients is 3, as 3 is the only number by which 3, 12, 9 and 36 are all divisible.

------------------------

The symbolic coefficients are: [tex]x^3y, xy, x^2y, y[/tex]

The only common term is y, so y is the gcf of the symbolic coefficients.

------------------------

The gcf of the entire expression is the multiplication of the gcfs of the numeric and of the symbolic coefficients, so it is 3y.

Now, to factore the expression:

[tex]3x^3y + 12xy - 9x^2y - 36y = 3y(\frac{3x^3y}{3y} + \frac{12xy}{3y} - \frac{9x^2y}{3y} - \frac{36y}{3y}) = 3y(x^3 + 4x - 3x^2 - 12)[/tex]

The factored expression is:

[tex]3y(x^3 + 4x - 3x^2 - 12)[/tex]
