Answer: 397.39 cm2
Step-by-step explanation:
Hi, first we have to calculate the area of the circle:
Area of a circle = π x r^2
Replacing with the values:
A(C) =π x 12^2 = 452.39cm2
Now, we have to calculate the rectangle area:
Rectangle area = width x length = 5 x11 = 55cm2
Finally, since the shaded region is the circle and the rectangle is inside of it, we have to subtract the area of the rectangle to the area of the circle:
452.39 -55 = 397.39 cm2

A point on the top of the Leaning Tower of Pisa is shifted about 13.5 ft horizontally compared to the tower's base. To the nearest degree, how many degrees does the tower tilt from vertical?
Without the exact height of the Leaning Tower of Pisa, we cannot find the specific degree of tilt. However, given the height is approximately 183.27 ft, we can use the tangent function to roughly find that the tilt is near 4.22 degrees.
Explanation:The question involves the concept of trigonometry, specifically the tangent function, to calculate the angle of tilt of the Leaning Tower of Pisa. Assuming the tower forms a right triangle with the ground, we can utilize tangent, which is the ratio of the opposite side (the horizontal shift) to the adjacent side (the height of the tower) to determine the angle of tilt. Thus, the angle of tilt θ is calculated as θ = tan⁻¹(13.5/height). Unfortunately, without the exact height of the tower, we cannot give a specific degree of tilt.
However, the actual height of the tower is roughly 183.27 ft. Substituting that value into the equation gives θ = tan⁻¹(13.5/183.27), which approximates to around 4.22 degrees when calculated.

Using trigonometry and taking into account the horizontal shift and height of the Leaning Tower of Pisa, we found that it tilts around 4 degrees from vertical. The procedure entails determining the tangent of the tilt angle and using the arctan function to calculate the angle in degrees.
The problem involves finding the tilt angle of the Leaning Tower of Pisa given its horizontal displacement. We will consider the height of the tower, which is approximately 55 meters (about 180.45 feet).
We can use trigonometry, specifically the tangent function, tan(θ) = opposite/adjacent, to find the angle of tilt. Here, the 'opposite' side is the horizontal shift (13.5 feet) and the 'adjacent' side is the height of the tower (180.45 feet).
Identify the opposite and adjacent sides:
Horizontal shift (opposite) = 13.5 feetHeight of the tower (adjacent) = 180.45 feetUse the tan function to find the angle:
tan(θ) = opposite / adjacent = 13.5 / 180.45Calculate the tangent value:
tan(θ) ≈ 0.0748Find the angle θ using the arctan function:
θ = arctan(0.0748) ≈ 4.28 degreesRound to the nearest degree:
θ ≈ 4 degreesTherefore, the Leaning Tower of Pisa tilts approximately 4 degrees from vertical.
Mr. Mole's burrow lies 5 meters below the ground. He started digging his way deeper into the ground,
descending 3 meters each minute.
Graph the relationship between Mr. Mole's elevation relative to the ground (in meters) and time (in
minutes)
Elevation (meters)
Answer:
If you are looking for coordinates then its (0,5) (5,-20)
Step-by-step explanation:
Mr. Mole's burrow lies 5 meters below the ground. This is the same as saying that when Time is 0, Elevation is -5.
Therefore, the graph of the relationship should pass through the point (0,-5)
We are also given the rate of change of the relationship: 3 meters per minute. This means that when Time increases by 1, Elevation decreases by 3.
Therefore, the graph should also pass through the point (0+1,-5-3), which is the point (1,-8) However, this point doesn't appear on the grid! We need to find an equivalent pair of corresponding changes that would help us find a point that we can graph.
Note, for instance, that when Time increases by 5, Elevation decreases by 5x3= 15. Therefore, the graph should pass through the point
(0+5,-5-15)which is the point (5,-20)
Sorry if its confusing :(

Which of these is a simplified form of the equation 8y + 4 = 6 + 2y + 1y?
5y = 2
5y = 10
11y = 2
11y = 10
Answer:
5y = 2
Step-by-step explanation:
To solve this equation, you have to simplify both sides of the equation, and arrange the terms so that all the values with a variable are on one side, and all the values without a variable are on the other side:
8y + 4 = 6 + 2y + 1y
8y + 4 = 6 + 3y
8y - 3y = 6 - 4
5y = 2
In a game, if you roll a 2 or a 3 on a 6-sided number cube, you lose a turn. NOTE: This is just using one number cube. a. What is the probability that you roll a 2 or 3, P (2 or 3)? Explain your reasoning. (2 points possible) b. What is the probability that you don’t roll a 2 or a 3, P (NOT a 2 or 3)? Explain your reasoning.
Answer:
(a)1/3
(b)2/3
Step-by-step explanation:
This is a 6-sided number cube, therefore total possible outcomes, n(S)=6
(a)Probability of rolling a 2 OR 3 =P(2)+P(3)
[tex]=\dfrac{1}{6} +\dfrac{1}{6} =\dfrac{2}{6}\\= \dfrac{1}{3}[/tex]
(b)Probability of not rolling a 2 OR 3
In probability, the sum of the probability of an event and its complement is always 1.
Therefore:
P(Rolling a 2 or 3)+P(Not rolling a 2 or 3)=1
From part (a) above:
Probability of rolling a 2 OR 3=[tex]\dfrac{1}{3}[/tex]
Therefore:
[tex]\dfrac{1}{3}+$P(Not rolling a 2 or 3)=1\\P(Not rolling a 2 or 3)=1-\dfrac{1}{3}=\dfrac{2}{3}[/tex]

Brian invests £1300 into his bank account.
He receives 10% per year simple interest.
How much will Brian have after 3 years?
Give your answer to the nearest penny where appropriate.
Answer:
£1690
Step-by-step explanation:
Amount invested by Brian = £1300
rate of simple interest = 10%
To find money Brian will have after three years
He will have amount invested in bank and interest earned in three years from that amount.
Simple interest for any principal amount p is given by
SI = P*R * T /100
where SI is simple interest earned
T is time period for which simple interest is earned
R is rate of interest
Substituting value of P , R and T we have
SI = 1300*10* 3 /100 = 390
Therefor interest earned will be £390
Total money with Brian after three years = principal amount invested + interest earned in 3 years
= £1300 + £390 = £1690

What are the solutions of x2 -7x+13 = 0 ?
Answer:

x =(7+√-3)/2=(7+i√ 3 )/2= 3.5000+0.8660i
Step-by-step explanation:
Step by step solution :
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-7x+13
The first term is, x2 its coefficient is 1 .
The middle term is, -7x its coefficient is -7 .
The last term, "the constant", is +13
Step-1 : Multiply the coefficient of the first term by the constant 1 • 13 = 13
Step-2 : Find two factors of 13 whose sum equals the coefficient of the middle term, which is -7 .
-13 + -1 = -14
-1 + -13 = -14
1 + 13 = 14
13 + 1 = 14
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Equation at the end of step 1 :
x2 - 7x + 13 = 0

The Area of Pentagon is 363.43 mm².
What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.
We have, Apothem= 10mm
So, Perimeter of Pentagon
= 10 x 7.267
= 72.67 mm
Now, side of pentagon = 72.67/ 5= 14.534 mm
So, Area of Pentagon
= 1/4 √5(5+2√5) a²

What lines are parallel to the line y= 6x + 8
Answer:
y = 6x + 24
Step-by-step explanation:
Remember, any line can be parallel to y= 6x + 8 as long as it has the same slope (m, or in this case 6), and a different b (in this case 8).
Solve for y! 8x - 4y = -28
y = 2x + 7 in the equation 8x - 4y = -28, isolate y on one side by subtracting 8x from both sides and then dividing by -4.
Solve for y: 8x - 4y = -28
Start by isolating y on one side of the equation.
Subtract 8x from both sides to get -4y = -8x - 28.
Finally, divide by -4 to find y = 2x + 7.
Find the third side in simplest radical form:
Answer:
The third side is 8
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse
a^2 + 15^2 = 17^2
a^2 +225 = 289
Subtract 225 from each side
a^2 +225-225=289-225
a^2 = 64
Take the square root of each side
sqrt(a^2) = sqrt(64)
a= 8
