Min's hose can pump 21 gallons of water every hour. How many gallons of water will he fill up if he runs the hose for 2/3 of an hour?

Answers

Final answer:

Min's hose will fill up 14 gallons of water if it runs for 2/3 of an hour, based on its rate of 21 gallons per hour.

Explanation:

The question asks us to calculate how many gallons of water Min's hose can pump if it runs for 2/3 of an hour, given that it pumps water at a rate of 21 gallons per hour.

First, we need to find out how much water the hose would pump in one hour and then calculate 2/3 of that amount:

Full capacity in one hour: 21 gallons

Capacity in 2/3 of an hour: (21 gallons) * (2/3) = 14 gallons

So, Min's hose will fill up 14 gallons of water if it runs for 2/3 of an hour.

therefore

The cost of one burger is $2.95

The cost of one fry is $1.45

What is the value of d? Assume that the line is tangent to the circle.

Answers

Answer:

121°

Step-by-step explanation:

We have been given a chord and tangent to a circle, and also a minor arc measure that is equal to 118°We know that; An angle formed by a secant and tangent of circle is half of the measure of intercepted arc.

Therefore; ∠ x = 1/2 mABC

We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.

Thus; 360° - 118° = 242°

Using the formula; ∠ x = 1/2 mABC

Then; d = 242/2

            = 121°

which construction of parallel lines is justified by the theorem "when two lines are intersected by a transversal and the corresponding angles are congruent, the lines are parallel"?​

Answers

Answer:

im positive that the answer is c because when you look at where the arcs meet to the parallel lines, if you were to make a line connecting the two points, you would have a parallel line to the transversal

-please mark as brainliest if this helped:)

Step-by-step explanation:

The corresponding angles are equal. Then the diagram which justified the parallel lines and corresponding angles is C.

What are parallel lines?

When the distance between the lines is constant then the lines are called parallel lines. The lines do not intersect when they are separated from each other. And the slope of the lines is equal.

Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.

When two lines are intersected by a transversal and the corresponding angles are congruent, the lines are parallel.

Which of the following measurements is a little more than 3 feet? meter,centimeter,centileter, 1/4 foot

Answers

Answer:

The correct answer option is: meter.

Step-by-step explanation:

We are to determine whether which of the given measurements is a little more than 3 feet.

To find that, we will use the conversion:

1 meter = 3.28084 foot

1 centimeter = 0.0328084

1/4 foot [tex] \neq [/tex] 3 foot

Keeping these values in front of us, we can clearly see that its the unit meter which is equal to a little more than 3 feet.

Final answer:

The measurement that is a little more than 3 feet is a meter, which is approximately 3.28 feet, whereas a yard is equal to 3 feet. Meters are used to measure larger objects and distances.

Explanation:

The correct answer to which measurement is a little more than 3 feet is a meter. A meter is a unit of length in the metric system, and it is used to measure larger objects or distances. One meter is approximately equal to 3.28 feet, which makes it slightly longer than a yard (3 feet).

Comparatively, a centimeter is much smaller, with 100 centimeters making up 1 meter. A ruler typically contains markings for centimeters and can also include millimeters, which are even smaller units of the metric system – there are 10 millimeters in one centimeter.

When comparing metric to customary units, a yard is the closest customary unit in length to a meter. Since there are 3 feet in a yard, and a meter is roughly 3.28 feet, a meter stick is somewhat longer than a yardstick.

Therefore, among the options provided (meter, centimeter, centileter, and 1/4 foot), the measurement that is a little more than 3 feet is a meter.

george wanted to measure the angle of a waterslide at the lake .he used a sheet of folded paper that formed 20 degree angle. he measured and found that three of the folded paper angles would fit in the angle made by the slide and the ground . what is the angle of the waterslide ?​

Answers

Final answer:

The angle of the waterslide, as measured by George using the folded paper, is 60 degrees. He found this by multiplying the paper angle of 20 degrees by the number of paper angles (3) that fit in the slide's angle.

Explanation:

The question is asking for the angle made by the waterslide and the ground. Given that a sheet of folded paper forms a 20-degree angle, and three of these paper angles fit in the angle made by the slide, we need to find the total angle.

To solve this problem, you simply multiply the angle of the paper by the number of paper angles that fit in the slide's angle. Here's how you do it:

Identify the angle of the paper, which is 20 degrees. Identify the number of paper angles fitting in the slide's angle, which is 3. Multiply these together. That is 20 degrees * 3 = 60 degrees.

So, the angle of the waterslide is 60 degrees.

the graph of y=sinx is reflected on the line x=y then on y=2 the resulting graph has which equation​

Answers

Answer:

y = 4 - sin⁻¹x

Step-by-step explanation:

1. Reflection about y = x

If we reflect a function ƒ(x) about the line y = x, we are creating its inverse, ƒ'(x).

Thus, reflection of y = sinx  about y = x gives y = sin⁻¹x.

The range of the reflection extends from -∞ to +∞, but the range of the function y = sin⁻¹x is [-π/2, π/2] (see Fig. 1) .

2. Reflection about y = 2

Reflection about y = 2 retains the sign of x but changes the sign of y.

Note, however, that in Figure 2 the point at (0, 0) is reflected to (4, 0).

The function is translated up by four units.

After the two reflections, the equation of the line is

y = 4 - sin⁻¹x

find the equation of the line that is parallel to the x-axis and goes through (4,-3)​

Answers

Answer:

y = 3

Step-by-step explanation:

Parallel lines are lines which do not intersect. If the line is parallel to the x-axis then it is a horizontal line that intercepts the y-axis at the y-coordinate of the point (4,-3). So the equation of the line is y = b where b is the y-coordinate or y-intercept. Here it is y = 3.

Start at point A (-2,5). Translate it 3 units left and 4 units up on the coordinate plane. How will this affect the x- and y- coordinates of the point? Where will point A' be after the translation.

Solve and graph the absolute value inequality: |2x + 1| ≤ 5.

Answers

Answer:

–7/2 ≤ x ≤ 5/2

Step-by-step explanation:

Given in the question an inequality

| 2x + 1 | ≤ 5

–5 ≤ 2x + 1 ≤ 5

–6 – 1 ≤ 2x + 1 -1 ≤ 6 – 1

–7 ≤ 2x ≤ 5

–7/2 ≤ x ≤ 5/2

Then the solution to | 2x + 1 | ≤ 5 is the interval –7/2 ≤ x ≤ 5/2

Graph is attach below

Final answer:

The solution to the absolute value inequality |2x + 1| ≤ 5 is the interval -3 ≤ x ≤ 2. To find this, two separate inequalities are solved based on the non-negative and negative cases within the absolute value. The graphical representation is a closed interval from -3 to 2 on the number line.

Explanation:

To solve and graph the absolute value inequality |2x + 1| ≤ 5, we need to consider two cases based on the definition of absolute value.

If the expression inside the absolute value is non-negative (2x + 1 ≥ 0), then the inequality becomes 2x + 1 ≤ 5.If the expression inside the absolute value is negative (2x + 1 < 0), then the inequality becomes -(2x + 1) ≤ 5 which simplifies to 2x + 1 ≥ -5.

We then solve these two inequalities:

2x + 1 ≤ 52x ≤ 4x ≤ 22x + 1 ≥ -52x ≥ -6x ≥ -3

The solution set is the intersection of these two sets of numbers, which is -3 ≤ x ≤ 2. Graphically, this is represented on the number line as a closed interval from -3 to 2.

Answers

Answer:

23

Step-by-step explanation:

4c = 92

He needs to solve for c. He needs c alone on the left side. c is being multiplied by 4. The opposite operation to multiplication is division, so he needs to divide the left side by 4. The rule with equations is that you must do the same operation to both sides, so he must divide both sides of the equation by 4.

4c/4 = 92/4

c = 23

Answer: He needs 23 cans of balls.

Answer:

23

Steps:

1) Put it into a equation:

4 • C = 92

2) divide both sides:

4 divided by 4 = crosses out

92 divided by 4 = 23

3) C=23
