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.

Answer:

Option 4: [tex]\frac{8\frac{1}{2} }{\frac{5}{6} } =x[/tex]

Step-by-step explanation:

Total length of the board = [tex]8\frac{1}{2}[/tex] feet

Length of the smaller board to be cut = [tex]\frac{5}{6}[/tex] feet

So,

[tex]8\frac{1}{2} =\frac{5}{6} +\frac{5}{6} +\frac{5}{6} ....x[/tex] times.

[tex]8\frac{1}{2} =x(\frac{5}{6} )[/tex]

Given vertices ofQuadrilateral RSTU as R(1,3), S(4,1), T(1,-3) and U(-2,-1).

We need to check if diagonals are congruent.

The coordinates of verticales diagonal RT are R(1,3) and  T(1,-3).

The coordinates of verticales diagonal SU are S(4,1), and  U(-2,-1),

By applying distance formula:

[tex]\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

RT = [tex]=\sqrt{\left(1-1\right)^2+\left(-3-3\right)^2}[/tex]=[tex]\sqrt{36}[/tex]

RT = 6

SU  [tex]=\sqrt{\left(-2-4\right)^2+\left(-1-1\right)^2}[/tex].

[tex]=2\sqrt{10}[/tex].

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.

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.

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. Here's a graph to show this is the correct answer.

The answer is actually x ≥ -3/4

Ask if the numerator and denominator can be divided by the same number, which is called a common factor.

See if at least one number in the fraction is a prime number.

Simply just find the least common factor between the numerator and the denominator of the fraction, For example, 2/4, you know that between the two numbers, they both share the same common factor,  2, so divide 2 on the top and the bottom, and then your final  answer would be 1/2. However, if there seems to be no common factor between the numerator and the denominator for a fraction, do not simplify it any more. You cannot have a decimal as a numerator or a denominator. For example,  3/5 has no common factor so you do not have to simplify it as it is already at its most simplest form.

17.3

Because the one in the hundredths place is less than 5, so you round down to make 17.3.

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

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.

with th information given we can express the equation:

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

where [tex]x[/tex] is the unknown number.

to clear for [tex]x[/tex] first we multiply the equation by 2, to eliminate the fraction:

[tex]2(2x-8=\frac{x}{2}-2 )\\4x-16=x-4[/tex]

moving all terms with [tex]x[/tex] to the left:

[tex]4x-x-16=-4\\3x-16=-4[/tex]

and adding +16 to each side:

[tex]3x-16+16=-4+16\\3x=12[/tex]

Answer:

it is not h^48. I just took the test and its h^24!

Step-by-step explanation:

d + mq = rp

or

rp + d = mq

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.

The slope-intercept representation of a linear function is given by the equation shown as follows:

y = mx + b

The coefficients m and b have the meaning presented as follows:

Jose grew at an average of 2 3/4 inches per year, hence the slope is given as follows:

m = 2.75.

Thus:

J(x) = 2.75x + b.

Jose was 63 inches tall when he was 13 years old(8 years after he was 5 years old), hence the intercept b is given as follows:

63 = 2.75(8) + b

b = 63 - 2.75 x 8

b = 41 inches.

When Jose and Sean were 5 years old Jose was 1 1/2 inches taller than Sean, hence Sean's height is given as follows:

41 - 1.5 = 39.5 inches.

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°.
