The diameter of a circle is 26 cm. Find its area to the nearest whole number.

Answers

Answer 1
area= pi x r^2
= pi x 13^2
=pi x 169
= 530.929
= to the nearest whole number 531
Answer 2

Answer:

531

Step-by-step explanation:

The area of a circle can be determined by the equation: A = πr².

The "r-value" represents the radius, which is half of the diameter. Since the diameter is in cm, the area will have the unit cm².

d = diameter       r = radius       π = 3.14.....       A = area

d / 2 = r

26 / 2 = r

13 cm = r

A = πr²

A = π(13)²

A = 169π

A = 530.929.... cm²

A = 531 cm²

As you can see, the radius was determined to be 13 cm. When you plug that value into the area equation, you get 530.9 cm². Rounding to the nearest whole number would bump the 0 to 1, making the final answer 531 cm².

Suppose you are running in a marathon for charity, looking to raise at least $1500. People may sponsor you by donating either $15 or $25 for every mile you run. However, you cannot have more than 100 people sponsoring you for this marathon.
Now, create a system of inequalities using the above information (use x and y as the variables).

Answers

Answer:

See below ~

Step-by-step explanation:

Let :

x = people donating $15 when you runy = people donating $25 when you run

Two inequalities created are :

15x + 25y ≥ 15003x + 5y ≥ 300 [Simplified] ⇒ Inequality 1x + y ≤ 100 ⇒ Inequality 2

Solving

x + y ≤ 10015(x) + 25(x) ⩾ $1500

Let the people paying $15 be "x" and $25 be "y"

1st inequality

15(x) + 25(x) ⩾ $1500

Beginning with the graph of f(x) = x2, what transformations are needed to form g(x) = 3(x + 2)2 – 1?

Answers

Answer:

g(x)=(x+3)2 we must find x? so x+3=0 x=-3 we transformation -3 on left

Step-by-step explanation:

can u answer my queston pleas on my acc

The transformations applied to f(x)=x² to form g(x)=3(x+2)² −1 are: Horizontal shift left by 2 units.

Vertical stretch by a factor of 3.

Vertical shift down by 1 unit.

To transform the graph of  f(x)=x² into g(x)=3(x+2)² −1, we can identify a series of transformations that have been applied to the original function.

The term (x+2)² inside the function g(x) indicates a horizontal shift to the left by 2 units compared to f(x).

This is a shift in the negative direction on the x-axis.

The coefficient 3 in front of (x+2)² indicates that the graph is vertically stretched by a factor of 3 compared to the graph of f(x).

The term −1 subtracted at the end of the function g(x) indicates a vertical shift downward by 1 unit compared to f(x).

This is a shift in the negative direction on the y-axis.

Hence, the transformations applied to f(x)=x² to obtain g(x)=3(x+2)² −1 are horizontal shift to the left by 2 units, vertical stretch by a factor of 3 and vertical shift downward by 1 unit.

What are the rules for rounding to the nearest hundred?

Rules for Rounding Numbers to Nearest 100. Rule 1: While round off to nearest 100, if the digit in the tens place is between 0 to 4 or <5, then the tens place is replaced by 0. Rule 2: If the digit in the unit’s place is equal to 5 or greater than 5, then the tens place is replaced by 0 and the hundreds place is increased by 1.

So 6,265 is between 6,200 and 6,300

6,265 rounded to the nearest hundred is 6,300

Therefore, The value is the closest estimate of this product is 6,300.

Maria plans to make a triangular center island along the road. The said plan is illustrated at the image attached. She was able to put a fence around the lot which measures LT = 3m and OL = 3m. The said land area is an example of an oblique triangle which does not contain any right angle. If m∠T = 70 and m∠L = 65, what could be the measurement of ∠O and TO (round off to the nearest whole number)?

WITH SOLUTION!!!​

Answers

To find ∠O

The sum of interior angles of triangle sum up to 180°

Hence,

∠O + 70° + 65° = 180°

∠O = 180° - 65° - 70°

∠O = 45°

∴ The angle ∠O is 45 degrees.

To find length of TO

Use cosine rule: a² = b² + c² - 2bc cos(A)

Hence,

TO² = 3² + 3² - 2(3)(3) cos(65)

TO² = 10.39287129

To = √10.4

TO = 3.22 ≈ 3 meters (rounded to nearest whole number)

∴ The length of TO is 3 meters.

Answers

Answer:

Step-by-step explanation:

When you are trying to find the mean of a number set, you are trying to find the average of the stats. As such, use the formula Sum of the Numbers / Total Number of Values.

In this case, we are adding 54 + 61 + 42 + 63 + 42 + 56 + 58, which is equal to 376. We are then dividing this by 7, which is equal to about 53.714.

Answers

The exchange rate of US dollars to Polish zloty is 1:3.1264. The correct option is b. 1:3.1264

Calculating exchange rates

From the question, we are to determine the exchange rate of US dollars to Polish zloty

From the given information,

Gary exchanged US dollars for Euros at a rate of 1:0.7716

That is,

1 US dollar = 0.7716 Euros

Also, he exchanged Euros for Polish zloty at a rate of 1:4.0518

That is,

1 Euro = 4.0518 Polish zloty

Now, we will find the value of 0.7716 Euros in Polish zloty

Since 1 Euro = 4.0518 Polish zloty

Then,

0.7716 Euro = 0.7716 × 4.0518 Polish zloty

∴ 0.7716 Euro = 3.1264 Polish zloty

But

1 US dollar = 0.7716 Euros

Therefore,

1 US dollar = 3.1264 Polish zloty

Hence, the exchange rate of US dollars to Polish zloty is 1:3.1264. The correct option is b. 1:3.1264

The theorems are:

Measure of the central angle = measure of intercepted arcMeasure of inscribed angle =1/2( measure of intercepted arc)Measure of inscribed angles with same intercepted arcs are congruent.

Using the circle theorems, given the inscribed angle, m∠ADB = 20°, we have:

m(AB) = 2(m∠ADB) = 2(20) = 40°

m∠AEB = m(AB) = 40°

m∠ACB = m∠AEB = m(AB) = 40°
