What is the unit rate for meters per second if a car travels 450 meters in 25 ​seconds?

Answers

Answer 1
m/s =meters per second
Answer 2

Answer:

18m/s

Step-by-step explanation:

Formula = 450 meters in 25 seconds

Average speed = 450m/25s

The unit rate is equivalent to 18m/s.

[Basically, just divide 450 meters by 25 seconds to get 18 meters per second. 18 is the unit rate :) ]

Robert can mow 3 1/2 acres in 3/4 of an hour on his riding lawn mower.

At this rate, how many hours will it take him to mow 8 acres?

Answers

Answer:

It will take 1 5/7 hours

Step-by-step explanation:

3/4 of an hour is;

3/4 * 60 minutes = 45 minutes

3 1/2 acres is done in 45 minutes

8 acres will be done in x minutes

Thus, mathematically;

3 1/2 * x = 8 * 45

7x/2 = 360

7x = 2 * 360

7x = 720

x = 720/7 minutes

Let us convert this to hours

That will be;

720/7/60 = 720/(60 * 7) = 720/420 = 12/7

= 1 5/7 hours

I'll mark you brainiest ---- find the range of possible values for the third side of a triangle if given two side lengths. 9yd, 32yd

Answers

Answer:

The third side of the triangle must have a length between 23 yd and 41 yd.

Step-by-step explanation:

Triangle Inequality Theorem

Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:

x + y > z

x + z > y

y + z > x

Combining the above inequalities, and provided y>z, the third size must satisfy:

y - z < x < y + z

We have to side lengths: y=32 yd and z = 9 yd, thus the range of possible values for the third side x is:

32 - 9 < x < 32 + 9

23 < x < 41

The third side of the triangle must have a length between 23 yd and 41 yd.

- Harvard university professor

The size 60 will produce the widest 95% confidence interval when estimating the population parameter.

What is confidence interval?

'A confidence interval is the mean of your estimate plus and minus the variation in that estimate.'

According to the given problem,

IN a sample with n number of people surveyed with a probability of a success of [tex]\pi[/tex] and a confidence level of 1-α , we have the following confidence interval of proportions.

[tex]\pi[/tex] ± [tex]z\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]

In which, z is the z score that has a p value of 1 -(α/2)

The margin of error is:

M = z [tex]\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]

The higher the margin of error, the wider an interval is.

As the sample size increases, the margin of error decreases. If we want, the widest possible interval, we should select the smallest possible confidence interval.

Hence, we can conclude that 60 is the correct answer.

Annie measures 9 teaspoons of lemon juice for a recipe. There are approximately 4.9 milliliters in one teaspoon. How many milliliters of lemon juice did Annie measure?

Answers

Answer:

44.1 milliliters of lemon juice

Step-by-step explanation:

Number of teaspoons of lemon juice = 9 teaspoons

Amount of milliliters in one teaspoon = 4.9 milliliters

Amount of lemon juice = Number of teaspoons × Amount of milliliters

                                      = 9 × 4.9

                                      = 44.1 milliliters

Step-by-step explanation:

x=2y.

x-21=3(y-21).

2y-21=3y-63.

42=y.

x=84.

Hope this helps plz hit the crown :D

Answer:

Daughter's present age = 42 years

Women's present age =  84 years

Step-by-step explanation:

Daughter's present age = x years

Women's present age = 2*x = 2x

21 years ago:

Daughter's age = x - 21

Women's age = 2x - 21

Women's age = 3*daughter'sage

2x - 21 = 3*(x - 21)

2x - 21 = 3x - 63        {Subtract '2x' from both sides}

   - 21   = 3x - 2x - 63

   -21    = x - 63             {Add 63 to both sides}

-21 +63 =  x

42  = x

Daughter's present age = 42 years

Women's present age = 2*42 = 84 years

Answers

Answer:

3 cm

Step-by-step explanation:

The area is the product of two dimensions, therefore the scale factor is:

A/A' = (b*r*h*r)/(b*h) = r²r² = 18/8r = √9/4 = 3/2 = 1.5

The length of the corresponding side will be:

Write the equation in slope-intercept form for the line that passes through (5, 4) and (6,-1).
SHOW YOUR WORK​

Answers

Answer:

y = -5x + 29

Step-by-step explanation:

Slope-Intercept Form of the Line

Given a line of slope m and y-intercept b, the equation of the line can be written as:

y = mx + b

The slope can be calculated by using the formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x1,y1) and (x2,y2) are the points through which the line passes.

We are given the points (5,4) and (6,-1), thus:

[tex]\displaystyle m=\frac{-1-4}{6-5}=\frac{-5}{1}=-5[/tex]

Now we use one of the points to find the value of b, for example (5,4):

4 = -5(5) + b

b = 25+4 = 29

Thus, the equation of the line is:

y = -5x + 29

Answers

Answer: R,G,Y,B,O  

Step-by-step explanation: Sample space is just any and all possible outcomes

The sample space of the given experiment is (R,G, Y, B, O). So option A is the correct one.

What is a Sample Space?

A sample space is a set of all the possible outcomes in a random experiment. It is usually denoted by the letter, S.

The subset of the sample space are events.

Given experiment is that you randomly choose a ball from a bag which consists of 5 balls.

Balls are 1 red (R), 1 green (G), 1 yellow (Y), 1 blue (B), and 1 orange (O).

Each ball is of different color.

When you randomly choose a ball, the chosen ball can be any of the colors given.

So sample space = (R,G, Y, B, O)

Hence the required sample space is (R,G, Y, B, O).

Find the point of intersection of the lines x-3 = 0 and y-5 = 0. ​

Answers

Answer:

x = 3 and y = 5

Step-by-step explanation:

Given equations are :

x-3 = 0 ....(1)

y-5 = 0 ....(2)

We need to find the point of intersection of the lines.

Add 3 both sides in equation (1).

x-3+3=3

x = 3

Now, add 5 to both sides of the equation.

y-5+5=0+5

y = 5

Hence, the required point of intersection of the lines is x = 3 and y = 5.
