Maria walked 3/4 of a mile. Cody walked 6/10 of a mile. How much farther did Maria walk than Cody?

Answer:

622.13 square units

Step-by-step explanation:

Area of the composite figure = area of parallelogram + area of circle

Note: 2 semicircles = 1 full circle

Area of the figure = a*h + πr²

Where,

a = 22

h = 11

r = ½ of 20 = 10

Plug in the value into the equation

Area = 22*11 + π*11²

Area = 242 + π*121

Area = 622.13271108 ≈ 622.13 square units (nearest tenth)

Answer:

scale factor = 1.2

Step-by-step explanation:

the scale factor is the ratio of corresponding sides image to original, that is

EZYD → TRAP

corresponding sides are the comparable sides on both , that is

EZ → TR

then

scale factor = [tex]\frac{EZ}{TR}[/tex] = [tex]\frac{12}{10}[/tex] = 1.2

Step-by-step explanation:

4:30/4

30 [tex]divided[/tex] by 4

7.5

4 divided by 4

1

7.5 minutes to 1 kilometer

since there are 60 minutes in a hour

60/7.5 = 8

8 x 1 = 8

.90° + 45° + x = 180°

{Sum of angles of triangles = 180°}

135° + x = 180°

x = 45°

61° + 90° + x = 180

151 + x = 180

x = 29°

31° + 90° + x = 180°

122° + x = 180°

x = 58°

x + 15° +90° = 180°

x = 180° - 105°

x = 75

The theoretical probability that the arrow will hit the small square on the upper left is approximately 9.8%. (Option A)

To determine the theoretical probability, we first need to calculate the areas involved. Let's start by finding the area of the entire circular target. The formula for the area of a circle is given by A = π * r², where 'r' is the radius. Plugging in the given radius (36 inches) into the formula:

A_circle = π * (36 inches)² ≈ 4069.73 square inches.

Next, we need to calculate the area of the small square in the upper left corner. Since the square is positioned at a corner of the circle, it forms a quarter of a circle. The area of this quarter circle can be calculated as follows:

A_quarter_circle = ¼ * A_circle. = ¼ * 4069.73 = 1017.43

Now, let's find the area of the square. The formula for the area of a square is A_square = side², where 'side' is the side length. Plugging in the given side length (5 inches) into the formula:

A_square = (5 inches)² = 25 square inches.

However, there are four identical squares inside the quarter circle, so the total area of all the squares combined is:

Total_Area_squares = 4 * A_square.

Now, to calculate the probability of hitting the small square in the upper left corner, we divide the area of that square by the area of the quarter circle:

Probability = (A_square / A_quarter_circle) * 100. = 25 / 1017.43 * 100 =  9.8%.

Hence the correct option is (a).

Answer:

O C. 5.76 in2

Step-by-step explanation:

To find the area of a square, the formula is

length x width = area

length = 2.4

width = 2.4

2.4in x 2.4in = 5.76 in2

in2 is the part of the answer since  in x in = in2

Answer:

m = 6.557

Step-by-step explanation:

Subtract 10 from both sides:

4m^2 = 172

Divide both sides by 4:

m^2 = 43

take the square root of both sides:

[tex]\sqrt m^2 = \sqrt{43[/tex]

m = 6.557

Does that make sense?

Using a trigonometric identity, considering the given value of the tangent of theta, the secant of the same angle is given by:

[tex]\sec{\theta} = \pm \sqrt{\frac{11}{8}}[/tex]

According to the following identity:

[tex]\sec^2{\theta} = 1 + \tan^2{\theta}[/tex]

In this problem, the tangent squared is given as follows:

[tex]\tan^2{\theta} = \frac{3}{8}[/tex]

Hence the secant is given by:

[tex]\sec^{2}{\theta} = 1 + \tan^2{\theta}[/tex]

[tex]\sec^{2}{\theta} = 1 + \frac{3}{8}[/tex]

[tex]\sec^{2}{\theta} = \frac{11}{8}[/tex]

[tex]\sec{\theta} = \pm \sqrt{\frac{11}{8}}[/tex]

Step-by-step explanation:

if we assume the angle on the ground to the truck is a ninety degree angle

The angle ∠DEF is equal to 90 degrees. Then the triangle ΔDEF will be a right-angle triangle.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function. The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The angle ∠DEG = 51° and angle ∠GEF = 39°.

Then prove that the triangle ΔDEF will be a right-angle triangle. Then we have

We know that if one angle of the triangle is 90 degrees then the triangle will be named a right-angle triangle.

The sum of the angle ∠DEG and ∠GEF will be

∠DEF = ∠DEG + ∠GEF

∠DEF = 51° + 39°

∠DEF = 90°

Then the triangle ΔDEF will be a right-angle triangle.

Answer:

Center= (-6,-8)

Radius= 6

Step-by-step explanation:

We use the formula (x-h)^2+(y-k)^2 then plug in our numbers:

[tex](x - h)^2 + (y - k)^2 = r^2\\(x+6)^2 +(y-k)^2=36[/tex]

In the equation -h is 6 so our h (x-coordinate) is -6

In the equation -k is 8 so our k (y-coordinate) is -8

In the equation r^2 is 36 so we take the square root of 36 to get r which is 6.
