Answer: 144 dresses in 1440 minutes.

Step-by-step explanation:

Divide 144 and 12 you get 12. So you multiply 12 and 120 and you get 1440.

The rate is 120min/12dresses. Let's simplify it.

12/120 = 10min/1dress (or just 10)

Lets use this rate for 144 dresses

10 x 144 = 1140

It will take 1440 minutes to sell 144 dresses.

Answer: 41.7 feet from pitcher to 1st

13.2 feet from pitcher to 2nd

58 degrees to turn from home to 1st

distance from pitcher to the line from home to 1st is 57.5(sin45) = 57.5(.707) = 40.66

construct a right triangle with legs 40.66 and 50-40.66 = 9.34.  then sum the legs' squares, and take the square root to get 41.72 feet

distance from home to 2nd = hypotenuse of a right triangle with sides 50 and 50, and angle of 45 degrees

50^2 + 50^2 = 2(2500) = 5000.  sqr5000= 70.71,  subtract 57.5.    70.71-57.5= 13.21 feet from pitcher to 2nd

Step-by-step explanation:

Using the theories of Application of derivative,we got that  59.11221inches³/sec  is rate of volume changing when the radius is 2.3 inches.

We are given rate of change of radius (dr/dt)=0.6inches

We know very well that volume of sphere is given by (4/3)πr³

where r is the radius of the sphere.

Now, differentiating the volume with respect to radius, we get

=>dV/dr=4πr²

=>dV/dt=(dv/dr)·(dr/dt)

=>dV/dt=4πr².(dr/dt)

We are given that dr/dt=0.6inches/sec

So, dV/dt=4πr²·(0.6)

Now, putting values of r=2.3

 dV/dt=4π(2.3)²×(0.6)

=>dV/dt=4×3.14×2.3×2.3×0.6

=>dV/dt=59.11221inches³/sec

Hence, if we suppose suppose that the radius is expanding at a rate of 0.6 inches per second, the volume is changing at the rate of 59.11221inches³/sec when the radius is 2.3 inches.

Step-by-step explanation:

let's use the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

so,

5.4/sin(K/2) = 12.3/sin(M1)

8.2/sin(K/2) = x/sin(M2)

M1 + M2 = 180 (as complementary angles or linear pair)

M2 = 180 - M1

sin(K/2) = 5.4×sin(M1)/12.3

sin(K/2) = 8.2×sin(M2)/x

therefore

5.4×sin(M1)/12.3 = 8.2×sin(180 - M1)/x

since sin(a) = sin(180 - a)

5.4×sin(M1)/12.3 = 8.2×sin(M1)/x

and then

5.4/12.3 = 8.2/x

x×5.4 = 8.2×12.3

x = 8.2×12.3/5.4 = 18.67777777... ≈ 18.7

Step-by-step explanation:Step-by-step explanation:

let's use the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

so,

5.4/sin(K/2) = 12.3/sin(M1)

8.2/sin(K/2) = x/sin(M2)

The mean is 76 and the standard deviation is 7.

What is mean and standard deviation?

The standard deviation in statistics is a measurement of how much a group of values can vary or be dispersed. A low standard deviation suggests that values are often close to the set's mean, whereas a large standard deviation suggests that values are dispersed over a wider range.

In mathematics, particularly in statistics, there are various types of means. Each mean summarizes a particular set of data, frequently to help determine the overall significance of a particular data set.

Let, 95% of students in statistics scored between 62 and 90 points.

Here,

Mean = [tex]\frac{62+90}{2} = \frac{152}{2} = 76[/tex]

And the standard deviation is,

SD = [tex]\frac{90-76}{2}= \frac{14}{2} = 7[/tex]

Hence, the mean is 76 and the standard deviation is 7.

The required value of the expression (2x − 12) + (1/2 xy - 10) for x = 8 and y = 2 is 2. Option D is correct.

First, let us understand the algebraic expression and how is it formed:

A multitude of strategies is used to build algebraic expressions utilizing variables and constants. It is a term-based mathematical expression that comprises variables, constants, and algebraic operations such as addition, subtraction, and so on.

We are given:

(2x − 12) + (1/2 xy - 10)

We need to find the value of the given expression for x = 8 and y = 2.

Substitute the values of x and y in the given expression, we will get;

(2 * 8 − 12) + (1/2 * 8 * 2 - 10)

= (16 − 12) + (8 - 10)

= 4 + (-2)

= 4 - 2

= 2

The equation of the line into slope-intercept form is y = x/3 - 6

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

From the question, we have the following equation that can be used in our computation:

9y−3x= −54

Rewrite properly

This gives

9y - 3x = -54

Divide through the equation by 3

So, we have the following representation

9y/3 - 3x/3 = -54/3

Evaluate

3y - x = -18

To rewrite as slope-intercept form is to make y the subject

So, we have

3y = x - 18

Divide through the equation by 3

So, we have the following representation

linear equation:

y = mx + b

1. find the slope m

first select two point

im gonna take point 1 (-1,-7) and point 2 (3,9)

m = (y2-y1)/(x2-x1)

m = (9-(-7))/(3-(-1)) = 16/4 = 4

2. find b

first select a point

im gonna reuse point 2 (3,9)

y = mx + b

9 = 5(3) + b

9 = 15 + b

b = 9 - 15 = -6

The train will catch up with the dog in 1.996 seconds

The problem is solved using the formula for speed which is

distance / time

speed of the train = length of track / time

= 1900 / 40

= 475 m/s

speed of the dog is given to be 6 m/s

The relative velocity = 475 - 6 = 469 m/s

The time to catch up is calculated using relative velocity

469 * time = 936 meters

time = 936 / 469

20 ft = 240 inches (I'm assuming there is an error in the question and the width is 20 ft, NOT 20 inches!)

360/15 = 240/x

x is the width of the scaled down rectangle

solve for x:

The probability that at least one of the cards drawn is a 3 is 1/5 0r 0.2000.

What is probability?

Probability shows the likelihood of an event happening.  It can be calculated by dividing the number of outcomes of an event by the total number of possible outcomes or sample space. Probability is equal to '1' when the event is certain to occur. i.e P =1. It is less than '1' when it is not likely to occur. i.e P< 1

Probability P=no. outcomes/total no. of the possible outcomes

From the question;

No. of total no of cards =5

The probability the card drawn is a 3  =1/5

                                                             =0.2000
