What is the smallest 9 digit number ni the form, aaa,aaa,aaa such that is divisible by 9??
Plz help!!

Answers

The smallest 9-digit number in the form aaa,aaa,aaa that is divisible by 9 is 111,111,111 because the sum of its digits is 9, which follows the divisibility rule for 9.

To find the smallest 9-digit number in the form aaa,aaa,aaa that is divisible by 9, we need to use the divisibility rule for 9. A number is divisible by 9 if the sum of its digits is also divisible by 9. Since we are looking for the smallest such number, we start with the smallest non-zero digit, which is 1.

The smallest 9-digit number where all digits are the same would be 111,111,111. Adding all the digits together, 1+1+1+1+1+1+1+1+1 equals 9, which is divisible by 9. Therefore, 111,111,111 is the smallest 9-digit number of the form aaa,aaa,aaa that is divisible by 9.

M-------> the coordinate that divides the directed line segment from A to B in the ratio of 2 to 3

we know that

A--------------M----------------------B
2 3
distance AM is equal to (2/5) AB
distance MB is equal to (3/5) AB
so

step 1
find the x coordinate of point M
Mx=Ax+(2/5)*dABx
where
Mx is the x coordinate of point M
Ax is the x coordinate of point A
dABx is the distance AB in the x coordinate
Ax=-2
dABx=(8+2)=10
Mx=-2+(2/5)*10-----> Mx=2

step 2
find the y coordinate of point M
My=Ay+(2/5)*dABy
where
My is the y coordinate of point M
Ay is the y coordinate of point A
dABy is the distance AB in the y coordinate
Ay=-4
dABy=(1+4)=5
Mx=-4+(2/5)*5-----> My=-2

the coordinates of point M is (2,-2)

At a local used car lot, one out of every three cars is red. If the car lot had 54 cars on it, how many cars are red SHOW WORK PLZ

Answers

Number of cars = 54

Number of red cars = 1/3 x 54 = 18

Answer: There are 18 red cars

Final answer:

To determine how many cars in the lot are red, we need to find one-third of the total number of cars. In this case, we are told that one out of every three cars is red, so the probability of a randomly chosen car being red is 1/3. The calculation is: Number of red cars = 54 * (1/3) = 18 cars.

Explanation:

To calculate how many cars out of 54 are red, we can multiply the total number of cars by the probability of a car being red:

Number of red cars = 54 * (1/3) = 18 cars

Therefore, there are 18 cars that are red in the lot.

–3x + 1 + 10x = x + 4

Answers

-3x+1+10x=x+4
1+7x=x+4
6x=3
x=.5

Alright so I will solve and explain as I go :)

First, let's combine like terms.

-3x + 1 + 10x = x + 4
7x + 1 = x + 4

Now, subtract the one from the left. (we do this to combine terms)

7x + 1 = x+ 4
7x = x + 3

Now subtract the x from the right. (this is also to combine terms)

7x = x + 3
6x = 3

Finally, divide by 6 on both sides.

6x = 3
x = 1/2 or 0.5

Hope this helps!

A recent poll taken by the movie theatre industry shows that 28% of the population attends a movie in a theater at least once a month. A sample of 300 people shows that only 12% of people attends a movie in a theater at least once a month. To determine whether this sample supports the population proportion of 0.28, a simulation of 100 trials is run, each with a sample size of 200 and a point estimate of 0.12. The minimum sample proportion from the simulation is 0.10, and the maximum sample proportion from the simulation is 0.28. What is the margin of error of the population proportion using half the range?

Answers

Answer:

The margin of error for this population proportion using half the range = ±0.09

Step-by-step explanation:

Confidence Interval is basically an interval of range of values where the true proportion can be found with a certain level of confidence.

Margin of Error is the width of the confidence interval about the central proportion.

For this question, the minimum sample proportion from the simulation is 0.10, and the maximum sample proportion from the simulation is 0.28, hence, the confidence interval for the question is (0.10, 0.28).

The width of this confidence interval = (Upper limit of the interval) - (Lower limit of the interval) = 0.28 - 0.10 = 0.18.

Hence, the margin of error for this population proportion using half the range, is 0.18/2 = 0.09.

Written appropriately as ±0.09.

Hope this Helps!!!

what is the equation of a circle with a center located at (4,-1) and a radius of 9

Answers

The equation for a circle with the given information would be (x - 4)^2 + (y + 1)^2 = 81.

This is because the base form of a circle is:

(x - x1)^2 + (y - y1)^2 = r^2

In which, x1 is the x coordinate of the center and y1 is the y coordinate of the center. r is the radius of the circle. So we plug in to those and simplify.

(x - 4)^2 + (y - -1)^2 = 9^2

(x - 4)^2 + (y + 1)^2 = 81

shari has 1 1/2 gallons of orange juice. She wants to serve the orange juice equally among her 12 friends. How many ounces of juice will each friend receive

Answers

So there are 128 ounces in a gallon.
So half a gallon would have 64 ounces
Now it says Shari has 1 1/2 which means we would add 128 ounces and 64 ounces together to get 192 ounces.
1 1/2 gallons = 192 ounces
Now we take the 192 ounces and divide it into 12 because she has 12 friends to share with.
192/12 = 16 ounces
Each friend with get 16 ounces of orange juice.

Different sizes of ribbon need to be cut to go around various shapes. All of the following sizes are in inches. π , √5 ,√8 ,2√5
(a)Without using your calculator, approximate the decimal equivalent of each number to the nearest tenth.
(b)Order the ribbon sizes from least to greatest. Use the original numbers given.

Answers

(a) To approximate [tex] \pi [/tex], we are going to use a compass to draw a cirle of radius 2 and circumference 12.5. Remember that [tex] \pi [/tex] is the ratio between the circumference of a circle and its diameter; since the diameter of a circle is two times its radius, we can find [tex] \pi [/tex] using the equation: [tex] \pi = \frac{cricunference}{2*radius} [/tex]
[tex] \pi = \frac{12.5}{2(2)} [/tex]
[tex] \pi = \frac{12.5}{4} [/tex]
[tex] \pi =3.125[/tex]
And to the nearest tenth:
[tex] \pi =3.1[/tex]

To approximate [tex] \sqrt{2} [/tex], we are going to use the Babylonian method:
Step 1. We are going to make a guess. Our guess is 2 because [tex] \sqrt{4} =2[/tex], so [tex] \sqrt{5} [/tex] must be close to 2.
Step 2. We are going to divide 5 by 2:
[tex] \frac{5}{2} =2.5[/tex]
Step 3. We are going to find the average between our initial guest and the result of our previous calculation:
[tex] \frac{2+2.5}{2} = \frac{4.5}{2} =2.25[/tex]
And to the nearest tenth: [tex] \sqrt{5} =2.2[/tex]

To approximate [tex] \sqrt{8} [/tex], we are going to use the Babylonian method one more time:
Step 1. Our guess is 3 because [tex] \sqrt{9} =3[/tex], so [tex] \sqrt{8} [/tex] must be close to 3.
Step 2. We are going to divide 8 by 3:
[tex] \frac{8}{3} =2.6[/tex]
Step 3. We are going to find the average between our initial guest and the result of our previous calculation:
[tex] \frac{3+2.6}{2} = \frac{5.6}{2} =2.8[/tex]
[tex] \sqrt{8} =2.8[/tex]

To approximate [tex]2 \sqrt{5} [/tex] we are going to multiply our approximation of [tex] \sqrt{5} [/tex] and multiply it by 2:
[tex]2 \sqrt{5} =2*2.2[/tex]
[tex]2 \sqrt{5}=4.4[/tex]

(b) Since we have our irrational numbers expressed as decimal approximations, we can compare them to arrange them form least to greatest:
2.2,2.8,3.1,4.4
Now, we just need to replace the decimal approximations with the original numbers:
[tex] \sqrt{5} [/tex],[tex] \sqrt{8} [/tex],[tex] \pi [/tex],[tex]2 \sqrt{5} [/tex]

We can conclude that ordering the ribbon sizes from least to greatest we get:
[tex] \sqrt{5} [/tex],[tex] \sqrt{8} [/tex],[tex] \pi [/tex],[tex]2 \sqrt{5} [/tex]

A small submarine starts at –1,260 feet in relation to sea level. Then it descends 5 feet per minute for 12 minutes. What is the new position of the submarine in relation to sea level? –1,260 + (–5)(12) = –1,260 + 60 = –1,200

Answers

The submarine is at -1260 ft.
It descends 5 ft/min for 12 min.
12 min * 5 ft/min = 60 ft.
It descended 60 ft, so you must subtract 60 ft from -1260 ft.
-1260 ft + (-5)(12) ft = -1260 ft - 60 ft = -1320 ft

The error in the last line in the problem is that (-5)(12) = -60, not 60.
The correct line is:
-1260 + (-5)(12) = -1260 - 60 = -1320

The new position of the submarine in relation to sea level is -1,200 feet.

Your calculation is correct. To find the new position of the submarine in relation to sea level after descending at a rate of 5 feet per minute for 12 minutes, you can use the formula:

New position = Initial position - (Rate of descent * Time)

In this case:

New position = -1,260 feet - (5 feet/minute * 12 minutes)

= -1,260 feet - 60 feet

= -1,200 feet

So, the new position of the submarine in relation to sea level is -1,200 feet.
