what is the proper way to solve this problem 879000- 21989=

Answer: 0.84

Step-by-step explanation:

From the given table of probability distribution P (green)= 0.16

Since , the sum of all the probabilities of all the events in a particular probability distribution is 1.

Therefore, The  probability of selecting anything but a green candy at random from a large bag  is given by :-

[tex]\text{P(not green)=1-P(green)}\\\\\Rightarrow\text{P(not green)}=1-0.16\\\\\Rightarrow\text{P(not green)}=0.84[/tex]

Hence, the  probability of selecting anything but a green candy at random from a large bag = 0.84

Megan worked for a total of 9 hours.

To find how long Megan worked, we need to subtract the additional amount she earned from the total amount she made. Let's say she worked for x hours. Her earnings can be calculated using the equation:

12x + 32 = 140. Subtracting 32 from both sides, we get 12x = 108. Dividing both sides by 12, we find that x = 9.

Therefore, Megan worked for 9 hours.

Answer:

The square-root of a number has 2 same factors being multiplied to get that number while a cubic-root of a number has 3 same factors being multiplied to get that number. For example, the square-root of 64 is 8 because 8 x 8 is 64. However, the cubic-root of 64 is 4 since 4 x 4 = 16 x 4 = 64.

Step-by-step explanation:

Finding the square-root of a number means finding two same numbers that when multiplied equal one number, while finding the cubic-root of a number means finding three same numbers that when multiplied equal one number. For example, the square-root of 64 is 8 because 8 x 8 is 64. However, the cubic-root of 64 is 4 since 4 x 4 = 16 x 4 = 64.

The square root of a number is found by multiplying it by itself, while the cube root is found by multiplying it by itself three times.

Finding the square root of a number is the process of finding a number that when multiplied by itself gives the original number. For example, the square root of 64 is 8, because 8 x 8 = 64.

Finding the cube root of a number is the process of finding a number that when multiplied by itself three times gives the original number. For example, the cube root of 64 is 4, because 4 x 4 x 4 = 64.

So, the main difference is that the square root involves multiplying a number by itself once, while the cube root involves multiplying a number by itself three times.

These lines would be perpendicular.

If we divide 3y+7 by 12, we would get 1/4y+7/12

Now, if we re arange for y, we get: y=-1/4x+7/3

In this case, the y intercept (7/3) does not matter, only the slope does. The slope must be the opposite reciprical of the other slope. For instace if the slope was 4, the perpendicular lines slope must be -1/4. That is the exact case we have above.

Final answer:

The measure of ∠z is 37°

Explanation:

To find the measure of ∠z, we can use the fact that the sum of the angles in a triangle is 180°. Thus, ∠x + ∠y + ∠z = 180°. Given that ∠x = 90° and ∠y = 53°:

90° + 53° + ∠z = 180°

Simplifying the equation:

143° + ∠z = 180°

Subtracting 143° from both sides:

∠z = 180° - 143°

∠z = 37°

The measure of angle ∠z is 37°.

The sum of the angles in any triangle is always 180 degrees. Since you've given me the measures of two angles, I can find the measure of the third angle using the following formula:

measure of angle ∠z = 180° - (measure of angle ∠x + measure of angle ∠y)

From the image, we know that:

measure of angle ∠x = 90° (given)

measure of angle ∠y = 53° (given)

Plugging these values into the formula, we get:

measure of angle ∠z = 180° - (90° + 53°)

measure of angle ∠z = 180° - 143°

measure of angle ∠z = 37°

Therefore, the measure of angle ∠z is 37°.

Answer: The yarn will be cut into 26 sections.

Step-by-step explanation:

Since we have given that

Length of piece of yarn = [tex]6\dfrac{1}{2}=\dfrac{13}{2}\ feet[/tex]

Length of section = [tex]\dfrac{1}{4}\ feet[/tex]

We need to find the number of sections that will be cut into:

So, the number of sections would be

[tex]\dfrac{13}{2}\div \dfrac{1}{4}\\\\=\dfrac{13}{2}\times \dfrac{4}{1}\\\\=13\times 2\\\\=26[/tex]

Hence, the yarn will be cut into 26 sections.

For these types of problems, there is a shortcut to eliminating an answer choice, look at the Y intercepts in the different choices and compare that to the graph.  In this case, you can eliminate A, because the line crosses at y=-2.

Now start at -2 on the y intercept and see which answer choice will make you hit another point on the line.

B can be eliminated because because you rise 3 and run 2, since you run a positive number, that means you move to the right, so that will eliminate that answer, but lead you to the correct one.  You can tell that rising positive 3 was correct, but now you have to move to the left so that would be a negative and you have to move 2 spaces.

So combining those two thoughts, -3/2 is what you would be looking for making D your answer.

Let X = the large #

    Y = the small #

We have 2 unknowns, therefore we need 2 equations to solve for them:

    X + Y = 61

    X = 3Y - 7

Using the substitution method we get:

    X + Y = 61                original equation

   (3Y - 7) + Y = 61        substituting for X

    4Y - 7 = 61                combine like terms

    4Y - 7 + 7 = 61 + 7    add 7 to both sides

    4Y = 68                     simplify

    4Y/4 = 68/4               divide both sides by 4

    Y = 17                       solve for Y

    X + Y = 61                 original equation

    X + 17 = 61                replace Y with 17

    X + 17 - 17 = 61 - 17  subtract 17 from both sides

    X = 44                        solve for X

Check your answer:

       X + Y = 61          X = 3Y - 7

     44 + 17 = 61        44 = 3(17) - 7

     61 = 61  check!     44 = 51 - 7

                                 44 = 44  check!

Therefore, the larger #(X) = 44 and the smaller #(Y)= 17.

Answer: 17.3

===========================================

Explanation:

Start with the value 17.318 and note that the tenths place is just after the decimal point, so it is the 3. The digit after the 3 is 1, which is not 5 or greater. So we just drop everything after the 3 and write 17.3 as our answer

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

the equation of a line in slope-intercept form is

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (- 4, - 3)

m = [tex]\frac{-3-3}{-4-0}[/tex] = [tex]\frac{-6}{-4}[/tex] = [tex]\frac{3}{2}[/tex]

Answer: 19.44 hours or 19 hours and 26 minutes.

Step-by-step explanation:

1. To lose 1 pound, a 200-person must burn 3,500 calories. Therefore, to lose 2 pounds that person must burn 7,000 calories.

2. If the person burns 180 calories by walking for 30 minutes or [tex]\frac{1}{2}[/tex] hour, to calculate the time in hours the person has to walk to lose 2 pounds, you can multiply 7,000 calories by  [tex]\frac{1}{2}[/tex] hour and divide by 180 calories:

[tex]time=\frac{(7,000Cal)(\frac{1}{2}h)}{180Cal}\\time=19.44h[/tex]

3. You have:

[tex]minutes=(0.44)(60)\\minutes=26.4min\\minutes=26min[/tex]

4. Then, you can express it as following:

19 hours and 26 minutes

To lose two pounds, a 200-pound person who burns 180 calories per 30-minute walk needs to burn 7,000 calories in total. This can be found by dividing the total amount to burn (7,000) by the amount burned per walk (180) and converting the result from minutes to hours and minutes.

To determine how much time this 200-pound person needs to walk to lose two pounds of weight, we need to first calculate the total amount of calories he or she needs to burn. Since it requires a 3,500-calorie deficit to lose one pound of weight, two pounds would require burning a total of 7,000 calories. Given that this person burns 180 calories per 30-minute walk, we can calculate the total amount of time required to burn these calories by walking. First, calculate the total walks needed by dividing the total calories to burn (7,000) by the amount of calories burned per walk (180). Then convert the result from minutes to hours and minutes.

The answer you are looking for is Y = 2/3X - 5.

To find this, you must fill in the equation Y = MX + B, where Y = -1, M = 2/3, and X = 6. Filling in for those variables, you should get -1 = 2/3(6) + B. Now, you solve for B. Multiply 6 and 2/3 together, by putting 6 over 1 and multiplying straight across. 6 times 2 is 12 and 1 times 3 equals. This will give you 12/3, which simplified, is 4. Then, subtract 4 from both sides to get B = -5. Finally, fill in Y = MX + B, but this time only fill in M (2/3) and B (-5). This making Y = 2/3X - 5 the answer.

Diagonal RT is not congruent to Diagonal SU.

Therefore, Quadrilateral RSTU  is not a rectangle because the diagonals are not congruent.

So, it is False.

Final answer:

The quadrilateral RSTU is not a rectangle due to not having all right angles, making it a parallelogram.

Explanation:

The given quadrilateral RSTU is not a rectangle. To determine if it's a rectangle, we need to check if all angles are right angles, which is not the case here even if the diagonals are congruent and RS and ST are perpendicular.

Since the angles are not all right angles, the shape formed is a parallelogram. A rectangle must have all angles as right angles, so these conditions do not define a rectangle.
