What is the slope of the line that cuts through the points (1, 2) and (5, 4)? a. 2 c. One-half b. -2 d. Negative one-half Please select the best answer from the choices provided A B C D

Answers

The slope of the line is 1/2 or one-half if the line that cuts through the points (1, 2) and (5, 4) option (c)  One-half is correct.

What is the slope?

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have a line that cuts through the points (1, 2) and (5, 4).

The slope of a line:

[tex]\rm m =\dfrac{4-2}{5-1}[/tex]

m = 2/4

m = 1/2

Thus, the slope of the line is 1/2 or one-half if the line that cuts through the points (1, 2) and (5, 4).

Houa bought 11 chicken wings for $23.10 . How much does each wing cost

Answers

Answer:

Answer = $2.10

Step-by-step explanation:

To solve this we take the total cost divided by the total number of chicken wings to get $2.10.

Hope that helps! :)

Answer:

1 wing = $2.10

Step-by-step explanation:

11 wings = $23.10

Let 1 wing = x

11x = 23.10

To solve for x, we divide both sides by 11 :

11x÷ 11 = 23.10 ÷11

x = 2.1

So 1 wing = $2.10

Solve the following linear equation:

Answers

Answer: x = -28

Step-by-Step Explanation:

3(2x + 12) = 2(2x - 10)
3 * 2x + 3 * 12 = 2 * 2x - 2 * 10
6x + 36 = 2 * 2x - 2 * 10
6x + 36 = 4x - 20
6x - 4x + 36 = -20
2x + 36 = -20
2x = -20 - 36
2x = -56
x = -56/2

Answers

Answer:

Equation: 2w + 2(2w) = 12

width = 2

length = 4

Step-by-step explanation:

Width is w

Length is 2 * width = 2w

Perimeter is 2w + 2l

Substitute 2w for L.

Perimeter is now 2w + 2(2w) = 12

Distribute the 2 to the parentheses.

2w + 4w = 12

Combine Like terms

6w = 12

Divide by 6 to solve for w.

w = 2

If w = 2, then the length = 4.

Answers

From the question given above, the ratio of L : W in simplified form is given as: 6 : 5. See the explanation below.

What is a ratio?

A ratio, simply, can be defined as the quantitative relationship that exists between two values which is indicative of the number of times one value can be obtained from the other.

What is the explanation for the solution above?

Step 1  - Indicate your assumptions

Let X be the width of one of the rectangles and let its height be Y.

It is clear from the image that:

4X = 3Y

Hence

(4/3)X  = Y

Therefore,

Lenght (L) = 3Y

= 3 (4/3)X

= 4X

Width (W) = Y + 2X

= (4/3)X + 2X

= (10/3)X

Therefore,

L : W =  4X: 10/3X

= 4:10/3

To remove the fraction, multiply both sides of the ratio by 3

= 12 : 10, furhter simplify by halving each value, and we have

= 6:5

Hence, the ratio L: W in simplified form is 6 : 5.

How many classrooms would be necessary to hold 1,000,000 inflated balloons? (Assume one balloon is about 1 ft3 and a typical classroom is about 35 ft × 50 ft × 15 ft. Round your answer to the nearest number of classrooms.)

Answers

38 classrooms (to the nearest whole number)

One balloon = 1 cube ft. Using this value and multiplying it by 1,000,000, we can find how much space all of these would take up. Since 1 times anything is just the unchanged value,
• a million inflated balloons = 1000000 ft^3.

The classroom has dimensions 35, 50, and 15 ft. We can use these values to find the classroom’s volume. The equation for Volume of a rectangular prism: V = lwh, where l is length, w is width, and h is height. Substitute given dimensions into this equation:
• V = 35*50*15 = 26250 ft^3.

now, what times 26250 will equal 1000000? Well, let’s set up an equation and solve for x, the number of classrooms.
• 26,250x = 1,000,000. Divide both sides by 26250 to get x alone:
• x = 38.0952.

Approximately 38 classrooms are necessary to hold 1,000,000 inflated balloons.

Check: when x is 38: 26,250(38) = 997,500 ft^3. When x is 39: 26,250(38) = 1,023,750 ft^3. x = 38 is more accurate.
**(I will note, however, that I’m not sure if you’re instructed to round according to the decimal rules or round UP a whole number because that extra .0952 needs to be included).

To hold 1,000,000 inflated balloons,

38 classrooms are needed.

What is volume?

In three-dimensional space,

the amount of space taken by an object is the volume of that object.

The volume of the cubic,

= length x width x height

Given:

The dimensions of the normal classroom are 15 ft × 50 ft × 35 ft.

The volume of the classroom,

= 15 ft by 50 ft by 35 ft.

= 26250 cubic feet.

The number of classrooms,

= 1,000,000 / 26250

Simplifying the fraction,

we get,

= 38.09

≈ 38 to the nearest whole number.

Therefore, 38 classrooms are required.

160 = x^2 + 6x                   Subtract 160 from both sides.

Recall the IBP formula,

Let

[tex]u = \sin(\pi n) \implies du = \pi \cos(\pi n) \, dn[/tex]

[tex]dv = e^n \, dn \implies v = e^n[/tex]

Then

[tex]\displaystyle I = e^n \sin(\pi n) - \pi \int e^n \cos(\pi n) \, dn[/tex]

Apply IBP once more, with

A linear equation can be written as:

Where a is the slope and b is the intercept.

For a line that passes through the points (x₁, y₁) and (x₂, y₂), the slope can be written as:

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

Here we have the two points (0.2, 3) and (0.4, 6), so the slope is:

Here are the directions:Write and solve a proportion to answer the question.34 is 75% of what number?34w= 12/16w= what?Can anyone please help me? 37.6 x ???=3760this question is basically:thirty seven point six times ?what? equals three thousand seven hundred and sixty15 POINTS AVALIBLE + BRAINLIEST !!!!thanks :) Which graph represents the function?f(x)=x + 1 A strong command or challenge is the idea for Consider the following intermediate chemical equations.3 equations. 1: upper C solid plus upper o subscript 2 gas right arrow upper C upper O subscript 2 gas Delta H 1 equals negative 393.5 kilojoules. 2: 2 upper C upper O gas plus upper O subscript 2 gas right arrow 2 upper C upper O subscript 2 gas Delta H 2 equals negative 566.0 kilojoules. 3: 2 upper H subscript 2 upper o gas right arrow 2 upper H subscript 2 gas plus upper O subscript 2 gas delta H 3 equals 483.6 kilojoules. The overall chemical equation is Upper C (s) plus upper H subscript 2 upper O (g) right arrow upper C upper o (g) plus upper H subscript 2 (g).. To calculate the final enthalpy of the overall chemical equation, which step must occur?Reverse the first equation, and change the sign of the enthalpy. Then, add.Reverse the second equation, and change the sign of the enthalpy. Then, add.Multiply the first equation by three, and triple the enthalpy. Then, add.Divide the third equation by two, and double the enthalpy. Then, add. A tank contains 180 gallons of water and 15 oz of salt. water containing a salt concentration of 17(1+15sint) oz/gal flows into the tank at a rate of 8 gal/min, and the mixture in the tank flows out at the same rate. the long-time behavior of the solution is an oscillation about a certain constant level. what is this level? what is the amplitude of the oscillation? The average starting salary for an editor at a textbook company is $39,800. The actual salaries can vary by less than $1,300. Which inequality canbe used to determine whether a salary, x, falls within this range? What is the range of starting salaries at the company?O A 11,300-x)
