A parachutist's speed during a free fall reaches 207 kilometers per hour. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 20 seconds of free fall? Do not round your answers.

Answers

Answer 1

The speed is 57.5 m/s and the parachutist will fall 1150 m in 20 seconds.

Explanation:
We start out with the ratio 207 km/1 hr.

We know that 1 km = 1000 m; this means 207 km = 207*1000 = 207000 m. This gives us 207000 m/1 hr.

We know that 1 hr = 60 minutes, so we have 207000 m/60 min.

We also know that 1 min = 60 seconds, so 60 min = 60*60 = 3600 sec; this gives us 207000 m/3600 sec.

Dividing this, we get 57.5 m/s.

In 20 seconds, the parachutist will fall 57.5(20) = 1150 m.

Answer 2

Answer:

1150 meters

Step-by-step explanation:

Speed of parachute = 207 kilometers per hour

Speed of parachute in meter /second = (207 x 1000)/ (60 x 60)

= 57.5 meter /second

Parachute fall for 20 seconds with a speed of 57.5 meter /second, Thus the distance covered in 20 seconds

= 57.5 meter /second x 20 seconds

= 1150 meters.

What are the coordinates of the vertex of the graph? Is it a maximum or minimum

Answers

first one........................................

Based on the graph, the coordinates of the vertex are at (0, -1), and since the parabola opens upwards, the vertex is a minimum.

Therefore, the correct answer is A:

(0,-1) ; minimum

The image shows a parabola opening upwards on a coordinate plane. The vertex of a parabola is the highest or lowest point on the graph, depending on whether the parabola opens downward or upward, respectively.

Here's a detailed explanation for identifying the vertex and determining if it is a maximum or minimum:

Step 1: Identify the Vertex

The vertex of a parabola in the form [tex]$y = ax^2 + bx + c$[/tex] can be found using the vertex formula [tex]$x = -\frac{b}{2a}$[/tex] for the x-coordinate and then substituting that back into the equation for y to find the y-coordinate. However, in this case, we can directly observe the vertex from the graph. It's the point where the parabola changes direction.

Step 2: Read the Coordinates from the Graph

From the graph, we can see that the vertex is at the origin of the parabola's turning point. It appears to be at (0, -1) by looking at where the axis of symmetry of the parabola intersects the y-axis.

Step 3: Determine Maximum or Minimum

Since the parabola opens upwards, as indicated by the shape of the graph, the vertex represents the minimum point of the parabola. If the parabola were to open downwards, the vertex would represent the maximum point.

Each blade on a windmill is in the shape of a triangle with a base of 7 feet and a height of 4 feet if there are four blades on the WinMail what is the total area of the blades

Answers

Given is the shape of a triangle with base = 7 feet and height = 4 feet.

We know the formula for area of triangle is given as follows :-

[tex] Area\; of\; Triangle=\frac{1}{2} *(Base)*(Height) \\\\
Area = \frac{1}{2} (7)(4) \\\\
Area = \frac{28}{2} \\\\
Area = 14 \;squared \;feet [/tex]

So, the area of a blade is 14 squared feet.

There are four blades on wind mill. Then area of all four blades would be 4 times 14.

Hence, total area of all four blades = 4 x 14 = 56 squared feet.

The total area of the four windmill blades, each with a base of 7 feet and a height of 4 feet, is 56 square feet.

The question involves calculating the total area of windmill blades, each shaped as a triangle. To find the area of a single blade, we use the formula for the area of a triangle, which is (base x height) / 2. For a blade with a base of 7 feet and a height of 4 feet, the area of one blade is:

Area = (7 ft x 4 ft) / 2 = 28 ft² / 2 = 14 ft²

Since there are four blades on the windmill, the total area of the blades can be calculated by multiplying the area of one blade by the number of blades:

Total area = 14 ft2 x 4 = 56 ft²

A sign says that the price marked on all music equipment is at a discount for 30% off. You buy an electric guitar for the same price of $315.
{Im only in 7th grade.}
What is the percent you pay? _____________
Write an equation to find the regular price of the item. __________________
What was the regular price? ____________

Answers

Hi there!

a. So the electric guitar is sold for a sale price of $315 after the discount. The discount was 30%. Even though we get that amount off, we still pay 70% of the original price, because 100% (original price) - 30% is 70%.

b. An equation that can help us find the regular price of the item is through writing and solving a proportion. Set it up like this:

315/x = 70/100

This is because 315 is part of the whole and is 70% of the value of x.

How to solve it:

Okay. Let's solve this by cross multiplying the values. 315 * 100 is 31,500. 70 * x is 70x. That simplifies to 31,500 = 70x. Didivde each side by 70 to isolate the x. 70x/70 cancels out. 31,500/70 is 450. Let's check this by multiply the number by 70% and see what happens. 450 * 70% (0.7) is 315. There. x = 450. The regular price was $450.

Final answer:

The percent paid after a 30% discount is 70% of the regular price. The equation to find the regular price is 0.70 * P = $315. Solving this gives us the regular price of the electric guitar, which is $450.

Explanation:

If a sign says that the price marked on all music equipment is at a discount for 30% off, and you buy an electric guitar for $315, we need to figure out the percent you actually pay and the regular price of the guitar.

Since the discount is 30%, you pay 100% - 30% = 70% of the regular price.

Let's call the regular price 'P'. The equation to find the regular price of the item after a 30% discount is:

0.70 * P = $315

To find the regular price 'P', we divide both sides of the equation by 0.70:

P = $315 / 0.70

P = $450

The regular price of the electric guitar before the discount was $450.

The number of taxi accidents is approximated by y equals negative 143.3 x squared plus 1823.3 x plus 6820 and the number of injuries is approximated by y equals negative 416.72 x squared plus 4416.7 x plus 8500. Let xequals0 represents 1990, xequals1 represents 1991, and so on.

Answers

Answer:
number of taxi accidents = 12235.2 which is approximately approximately 12235 accidents

Explanation:
The equation for the number of accidents is given as:
y = -143.3 x² +1823.3 x + 6820

We are given that:
x = 0 represents 1990
x = 1 represents 1991
Therefore:
x = 8 represents 1998

Now, all we have to do is substitute with the value of x = 8 in the equation of accidents to get the number of taxi accidents in 1998 as follows:
y = -143.3 (8)² +1823.3 (8) + 6820
y = -143.3 (64) + 1823.3 (8) + 6820
y = -9171.2 + 14586.4 + 6820
y = 12235.2

If we are asked to approximate the answer, then it would be approximately 12235 accidents

Find 0.8% of 1,046 what is 0.8% of 1,046

Answers

Your correct answer should be 8.368

The required answer would be 8.368 which is 0.8 percent of 1,046.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

For instance, If Mishali obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.

We have to determine the evaluation of 0.8% of 1,046.

⇒ 0.8% of 1,046

0.8% is expressed as 0.8/100 in fractional form

⇒ (0.8/100)(1,046)

0.8/100 is expressed as 0.008 in decimal form

⇒ (0.008 )(1,046)

Apply the multiplication operation, and we get

⇒ 8.368

Therefore, 0.8% of 1,046 would be 8.368.

B) The square root of 7 is greater than the square root of 7^2 because the square root of 7^2=7 and the square root of a number greater than 1 is greater than the number itself.

D) the square root of 7 is greater than 4/5 because 4/5 is less than 1 and the square root of a number greater than 1 is greater than 1.

Answers

Lets check the validity of each one of our statements:

Statement A is false. The square root of a number less than 1 is greater than the number itself. In fact, [tex] \sqrt{ \frac{4}{5} } = \sqrt{0.8} =0.89[/tex]. Since [tex]0.89[/tex] is greater than [tex]0.8[/tex], [tex] \sqrt{0.8} [/tex] is greater than [tex] \frac{4}{5} [/tex]; therefore, statement A is false.

Statement B is false. The square root of a number greater than 1 is less than the number itself. in fact, [tex] \sqrt{7} =2.64[/tex], whereas [tex] \sqrt{7^2} =7[/tex]. Since 2.64 is less than 7, [tex] \sqrt{7} [/tex] is less than [tex] \sqrt{7^2} [/tex]; therefore statement B is false.

Statement C is false. [tex] \sqrt{7} [/tex] is actually less than 7 divided by two, so there is no way that [tex] \sqrt{7} [/tex] is between 6 and 8. In fact [tex] \sqrt{7} =2.64[/tex]. Since 5 is greater than 2.64, [tex]( \sqrt{5} )^2[/tex] is greater than [tex] \sqrt{7} [/tex]; therefore, statement C is false.

Statement D is true. [tex] \sqrt{7} =2.64[/tex]. Since 2.64 is greater than 0.8, [tex] \sqrt{7} [/tex] is greater than [tex] \frac{4}{5} [/tex].

We can conclude that Jana should use statement D to create her list; also the correct order from least to greatest is: [tex] \frac{4}{5} [/tex], [tex] \sqrt{0.8} [/tex],[tex] \sqrt{7} [/tex], [tex]( \sqrt{5} )^2[/tex], [tex] \sqrt{7^2} [/tex]

find the edge length of the cube if the volume is 1/27

Answers

Final answer:

The edge length of a cube with a volume of 1/27 cubic units is 1/3 unit, as it's the cube root of the volume.

Explanation:

To find the edge length of a cube when the volume is 1/27:

Volume is equal to edge length to the third power.

Convert meters into centimeters.

Calculate the density by dividing mass by volume.

The question is to find the edge length of the cube if the volume is 1/27 cubic units. To find the edge length, we need to take the cube root of the volume, because the volume of a cube is equal to the cube of one of its edges (V = L3, where V is the volume and L is the edge length). Since the volume is 1/27, the edge length would be the cube root of 1/27, which is 1/3. Therefore, the edge length of the cube is 1/3 unit.

How much of a spice that is 30% salt should be added to 175 ounces of a spice that is 65% salt in order to make a spice that is 50% salt?

Answers

Answer: 131.25 ounces

--------------------------------------------------

Explanation:

We have two spices. Call them spice A and spice B

Spice A is 30% salt. We do not know how much of this spice to add, so we'll call it x. The x is a placeholder for a number
So on your paper you might write
x = amount of spice that is 30% salt (amount in ounces)
30% of x = 0.30*x is the amount of pure salt we have in spice A

Spice B is 65% salt. We have 175 ounces of this stuff.
65% of 175 = 0.65*175 = 113.75 ounces are pure salt
So we have 0.30x+113.75 ounces of total pure salt from the two spices combined

The total mix is x+175 ounces. We want 50% of the total mix to be pure salt, so 0.50*(x+175) is the expression that represents this.

Set the expression 0.30x+113.75 and 0.50*(x+175) equal to each other. Solve for x
0.30x+113.75 = 0.50*(x+175)
0.30x+113.75 = 0.50*x+0.50*175
0.30x+113.75 = 0.50*x+87.5
0.50*x+87.5 = 0.30x+113.75
0.50*x-0.30x = 113.75-87.5
0.20x = 26.25
x = 26.25/0.20
x = 131.25

The ratio of Paul’s age to Luis’s age is 2:3. The sum of their ages is 35 years. Find the age of each one.

PLZ HELP AND SHOW WORK :)

Answers

Paul is 14 and Luis is 21.

We can use the proportion as the coefficients of a variable, x, to help us solve this.

2x+3x=35 (because the ratio of their ages is 2:3, and the sum of their ages is 35)

5x=35

Divide both sides by 5:
5x/5 = 35/5
x = 7

This means that Paul's age is 2*7=14 and Luis's age is 3*7=21.

Final answer:

To find Paul and Luis's ages, the ratio 2:3 is translated to 2x and 3x, and with the sum of their ages being 35 years, we solve the equation to find x = 7. Therefore, Paul is 14 years old and Luis is 21 years old.

Explanation:

The question involves finding the ages of Paul and Luis given that the ratio of their ages is 2:3 and the sum of their ages is 35 years. To solve this, let's denote Paul's age as 2x and Luis's age as 3x, where x is a common multiplier. The equation based on the sum of their ages will then be:

2x + 3x = 35

Solving this equation, we combine like terms:

5x = 35

Now, divide both sides by 5 to find the value of x:

x = 35 / 5

x = 7

So, Paul's age is 2x which is 2 * 7 = 14 years, and Luis's age is 3x which is 3 * 7 = 21 years.

distribute
3x-6+35+52=180
combine like terms
3x+81=180
subtract 81 on both sides
3x=99
divide both sides by 3
x=33
plug in for x
3((33)+2)=
or 180-35-52=93

The value of x is 29.

The measure of angle C is 93.

What is a triangle?

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

The sum of the angles = 180

So,

From the triangle,

3(x + 2) + 35 + 52 = 180

3x + 6 + 35 + 52 = 180

3x + 93 = 180

3x = 180 - 93

3x = 87

x = 29

Now,

∠C = 3 (x + 2)

= 3 (29 + 2)

= 3 x 31

= 93

Thus,

The value of x is 29.

The measure of angle C is 93.
