Find the area given figure. A) 44 B)60 C) 84 D) 72

Answer:

C

Step-by-step explanation:

Use the Pythagorean Theorem.

[tex]a^2+b^2=c^2 \\ \\ 100^2+b^2=125^2 \\ \\ 10000+b^2=15625 \\ \\ b^2=5625 \\ \\ b=\sqrt{5625} \\ \\ b=75[/tex]

Answer:

-1

Step-by-step explanation:

0.5(5-7X) = 8 - (4X+6)

Expand the L.H.S by multiplying it by 0.5 and expand the bracket on the R.H.S by multiplying with -1

2.5 - 3.5X = 8 - 4X -6

Collect like terms

-3.5X + 4X = 8 - 6 - 2.5

0.5X = -0.5

Divide both sides by 0.5

X = -1

The ordered pairs that satisfy the equation 7x - y = 8 include (1,-1) and (9/7, 1).

To find an ordered pair that satisfies the equation 7x - y = 8, we can choose a value for either x or y and then solve the equation for the other variable. For example, if we choose x = 1, we substitute this into the equation to find the corresponding y value: 7(1) - y = 8 which simplifies to y = -1. Thus, the ordered pair (1, -1) is a solution to the equation. Another solution could be found by choosing y = 1 and solving the equation for x: 7x - 1 = 8, which gives x = 9/7. Thus, the ordered pair (9/7,1) is also a solution to the equation.

To determine the ordered pair that satisfies the equation, rearrange the equation to solve for y. Plug in different values for x to find corresponding values for y.

To determine the ordered pair that satisfies the equation 7x-1y=8, we need to solve for y.

Rearranging the equation, we get y=7x-8. This equation represents a linear relationship, where the value of y depends on the value of x.

By plugging in different values for x, we can find corresponding values for y.

For example, when x=0, y=(-8).

So the ordered pair that satisfies the equation is (0, -8).

Answer

A = C2 / (4 π) for the first question.  C = 2*π*square root of (A/π). for the second question.

Step-by-step explanation:

The area of a circle is given by the formula A = π r2, where A is the area and r is the radius. The circumference of a circle is C = 2 π r.

If we "solve for r" in the second equation, we have r = C / (2 π ). Now we use this to replace r in the first equation: A = π [ C / (2 π ) ]2.

When we simplify this, we get A = C2 / (4 π).

Now you can put your value of C into this equation and find A.

To find the area of a circle from its circumference, first find the radius using the circumference and then compute area. To find the circumference from the area, derive the radius from the area and then calculate the circumference.

To find the area of a circle using its circumference, you first need to find the radius of the circle. The formula to find the radius from the circumference is r = C/(2π), where C is the circumference of the circle, r is the radius, and π is Pi, approximately 3.14159265. After finding the radius, use the formula for the area of a circle, A = πr², where A is the area.

Circumference of a circle can also be determined from its area. The radius can be found using the formula, r = sqrt(A/π), where A is the area of the circle. Once the radius is known, you can find the circumference by the formula, C = 2πr.

Im Gonna Have to Say B

Step-by-step explanation:

what you do is you take one of them and multiply their speed by however many hours

in this case

[tex]14 \times 3[/tex]

[tex]18 \times 3[/tex]

then add the product giving you the distance apart

Final answer:

The Serenity and The Mystic will be 96 miles apart after traveling in opposite directions for 3 hours with speeds of 14 mph and 18 mph, respectively.

Explanation:

The question involves calculating the distance between two moving objects, specifically sailboats, traveling in opposite directions. To find out how far apart they will be after a certain time, we use the concept of relative speed.

If The Serenity travels at 14 mph and The Mystic travels at 18 mph, their speeds add up when moving away from each other. Hence, the combined speed at which they are separating is:
(14 mph + 18 mph) = 32 mph.

To find out how far they will be apart in 3 hours:
Distance = Speed × Time
Therefore, Distance = 32 mph × 3 hours = 96 miles.

So, after 3 hours, The Serenity and The Mystic will be 96 miles apart.

9 × 9 would be the answer or just 9. Since 9 × 9 = 81. So, I believe you could put 9 if there is only one x spot but if there is 2 you can put 9 × 9. Hope this helps! c:

A= 19,63 units.

Step-by-step explanation:

The area of a circle is given by π r^2. Where "r" represents de radius.

In this case we know that de diameter is 5 units. Given that the radius is half of the diameter, then r=5/2 = 2.5 units.

Then the area of a circle is:

A= π r^2 = π (2.5 units)^2 = 19,63 units.

None of these. All of these functions are defined as ratio of trigonometric functions.

Trigonometric functions have infinite zeroes, so when you put them in the denominator, they lead to infinitely many points of ill-definition.

Answer:

400° F = 204.4° C

Step-by-step explanation:

We are given a temperature 400 degree in Fahrenheit and we are to convert in into a unit called Centigrade (also known as Celsius).

We know that 0 degree Centigrade is equal to 32 Fahrenheit so we will use the following formula to convert these units:

(32°F − 32) × 5/9 = 0°C

(400°F − 32) × 5/9 = 204.4° C

Final answer:

To convert 400 degrees Fahrenheit to Celsius, you can use the formula: C = (F - 32) * 5/9. So, 400 degrees Fahrenheit is approximately equal to 204.4 degrees Celsius.

Explanation:

To convert a temperature from Fahrenheit to Celsius, you can use the formula: C = (F - 32) * 5/9. To convert 400 degrees Fahrenheit to Celsius, you can substitute the value of F as 400 in the formula: C = (400 - 32) * 5/9 = 204.4. So, 400 degrees Fahrenheit is approximately equal to 204.4 degrees Celsius.

Answer:

$2.75

Step-by-step explanation:

I hope this helps you

You need an additional $2.75 to purchase the turkey. In the bat and ball problem, the ball costs $0.05 and the bat costs $1.05.

To determine how much more money is needed to purchase the turkey, you need to subtract the amount of money you have from the cost of the turkey. Since the turkey costs $12.75 and you have $10, you simply calculate $12.75 - $10.00 which equals $2.75. Therefore, you need an additional $2.75 to buy the turkey.

Let's now look at a similar problem. If a bat and ball cost $1.10 in total and the bat costs $1.00 more than the ball, we can set up the equation to find the price of the ball. Let x be the cost of the ball in dollars. Then the bat would cost x + $1.00. Since together they cost $1.10, the equation would be:
x + (x + $1.00) = $1.10.

Solving for x gives:
2x + $1.00 = $1.10
2x = $1.10 - $1.00
2x = $0.10
x = $0.10 / 2
x = $0.05.

So, the ball costs $0.05 and the bat costs $1.05, which is $1.00 more than the ball.

Answer:

60 degrees

Step-by-step explanation:

C = 2(pi)r

The radius is 12 cm. We can find the circumference of a circle with radius 12 cm.

C = 2(pi)r = 2(3.14)(12 cm) = 75.36 cm

The length of the arc of the sector is 12.56 cm.

We can find the fraction this length is of the full circumference.

(12.56 cm)/(75.36 cm) = 1/6

The length of the arc of this sector is 1/6 the length of the circumference of the entire circle.

That means the angle of the sector is 1/6 the angle of an entire circle.

An entire circle has a central angle of 360 degrees.

1/6 * 360 degrees = 60 degrees

Answer:

5y=5

Step-by-step explanation:

Given equations

2x + y = 3      (i)

x - 2y = -1    (ii)

Multiplying equation (ii) by -2

Both sides of equation will be multiplies by -2.

-2(x-2y)= -2(-1)

The new equation will be

-2x+4y=2  => (iii)

Adding equation (iii)  with equation (i), adding respective sides of both equations

(2x+y)+(-2x+4y)=3+2

2x+y-2x+4y=5

5y=5

So, after multiplying equation (ii) by -2 and then adding it to the first equation will give 5y=5

Answer:

[tex]5y=5[/tex]

Step-by-step explanation:

[tex]2x + y = 3[/tex]

[tex]x - 2y = -1[/tex]

If equation two is multiplied by -2, then the equation becomes

[tex]x - 2y = -1[/tex] times -2 becomes

[tex]-2x + 4y = +2[/tex]

Now we add both equations

[tex]2x + y = 3[/tex]

[tex]-2x + 4y = +2[/tex]

Step-by-step explanation:

Dividing 5 by 6 not possible, add zero to to 5 to make it 50

so your quotient becomes 0. 8, you then multiply 8 by 6, it gives 48, you subtract 48 from 50, then you get 2 add zero at th back of 2, to make it 20.

Divide 20 by 6 again, then you will get 3, your quotient becomes 0.83, multiply 3 by 6, you will get 18, subtract 18 from 20, you will get 2, add 0 at the back of 2 to make it 20.

Divide 20 by 6, you will get 3, your quotient becomes 0.833. Multiply 3 by 6, you will get 18, subtract 18 from 20, you will get 2.

Add zero add the back of 2 to make it 20 and repeat the process.

To find the slope, subtract the y values over the x values.

- 5 - - 4 / 3 - - 2 - Since subtracting a negative is the same as adding a positive, you can rewrite the equation like this: - 5 + 4 / 3 + 2.

You are left with -1/5, this cannot be simplified so this is your final answer. I hope this helps and have a great day! :)

Only two points are needed through which the line passes.

Where:
