For this case we have that by definition, a flat angle is one that measures 180 degrees. It is observed that a flat angle is formed from the first to the second quadrant.

Now, we must add 55 degrees of the third quadrant, then:

[tex]180 + 55 = 235[/tex]

Thus, the angle formed is 235 degrees.

Step-by-step explanation:

30 divided by 4 = 7.5

75 divided by 10 = 7.5

The answer is C. Jason goes 2 miles per every 15 minutes. If Jason goes 10 miles you would multiply 15 by 5 and that is 75.

The distance between the point (-3, -4) and the line 2y = -3x + 6 is 23 ÷ 13.

The distance between the point (-3, -4) and the line given by the equation 2y = -3x + 6 can be found using the point-to-line distance formula:

D = |Ax + By + C| ÷ (A^2 + B^2)

Firstly, we want to put the line equation in the standard form of Ax + By + C = 0. Let us rearrange the given equation of the line to this form:

3x + 2y - 6 = 0

Where A = 3, B = 2, and C = -6. Using the point (-3, -4), we plug the values into the point-to-line distance formula:

D = |3(-3) + 2(-4) - 6| ÷(3^2 + 2^2)

D = |-9 - 8 - 6| ÷(9 + 4)

D = | -23 | ÷ 13

D = 23 /÷ 13

Since ÷ 13 is an irrational number, we can't simplify it further. Therefore, the distance is:

D = 23 ÷ 13

The y-coordinate of the midpoint of the vertical line segment is calculated by method B. Divide 15 by 2, which gives the midpoint's y-coordinate as 7.5.

To calculate the y-coordinate of the midpoint of a vertical line segment with endpoints at (0,0) and (0,15), you can use the method of dividing the y-coordinates of the endpoints by 2. In this case, you would divide 15 by 2 to find the midpoint's y-coordinate, which is method B. Divide 15 by 2. This is because the midpoint of a line segment is found by averaging the coordinates of the endpoints, and for the y-coordinates you add them together and then divide by 2. So, the calculation is (0 + 15) / 2, which equals 7.5. Thus, the midpoint of the segment is at the point (0, 7.5).

Answer:

The answer is 6.

Step-by-step explanation:

Remember,  Gloria can knit one block in 50 minutes, and they want to know how many blocks she can knit in 5 whole hours.

Which means, that is 5 squares in 4 hours, but we still have the 10 minutes from each of the 50 minutes.

So, you add up the 5 ten minutes (50 minutes) Which gives you a whole square.

Therefore, Gloria can knit 6 squares in 50 minutes.

Gloria can knit 6 blocks in 5 hours if she maintains her knitting rate of one block every 50 minutes.

Gloria can knit one block of a quilt in 50 minutes. To find out how many blocks she can knit in 5 hours, one should first convert the knitting time from hours to minutes. Since there are 60 minutes in an hour, 5 hours is equal to 300 minutes. Next, divide the total available knitting time by the time it takes to knit one block.

300 minutes / 50 minutes per block = 6 blocks
So, if Gloria knits at the same rate, she can knit 6 blocks in 5 hours.

ANSWER

A. {75, 145, 198, 214}

EXPLANATION

From the given information,the income is given by the function

[tex]f(x) = 2x + 54[/tex]

where f(x) is the income in dollars and x is the area in square meters of lawn mowed.

To find the area that corresponds to John's earnings, we equate the function to the earnings and solve for x.

For the area that corresponds to 204, we have

[tex]2x + 54 = 204[/tex]

[tex]2x = 204 - 54[/tex]

[tex]2x = 150[/tex]

[tex]x = 75[/tex]

For the area that corresponds to 344, we have:

[tex]2x + 54 = 344[/tex]

[tex]2x = 344 - 54[/tex]

[tex]2x=290[/tex]

[tex]x = 145[/tex]

For the area that corresponds to 450, we have

[tex]2x + 54 = 450[/tex]

[tex]2x= 450 - 54[/tex]

[tex]2x =396[/tex]

[tex]x = 198[/tex]

For the area that corresponds to 482, we have

[tex]2x + 54 = 482[/tex]

[tex]2x= 482 - 54[/tex]

[tex]2x = 428[/tex]

[tex]x = 214[/tex]

Answer:

Step-by-step explanation:

the answer is 365,412

Check the picture below.

make sure your calculator is in Degree mode.

Thus, the kite is height of 400 ft above the ground.

Hence, option B is correct.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that,

Hypotenuse of tringle = 520 ft

And inclination angle = 50.2 degree

We know that if any one of interior angle is of 90 degree then the angle is said to be right angle triangle.

Since,

sinΘ = (opposite side of Θ)/Hypotenuse

Therefore,

⇒ sin50.2 = Height/520         (since opposite side is height of triangle as shown in figure)

⇒ 0.76 = Height/520  

⇒ Height = 395.2 feet ≈ 400ft  (in nearest foot)

Hence,

Height of kite is 400 ft.

Answer:

Area of the parking lot = 6525 ft²

Explanation:

Since the two isosceles right-angled triangles have equal bases and heights, therefore, their areas are equal

Therefore:

Area of the parking lot = area of rectangle + 2*area of isosceles triangles

1- getting the area of the rectangle:

Area of rectangle = length * width

We are given that the dimensions of the rectangle are 45 ft and 100 ft

Therefore:

Area of rectangle = 45 * 100 = 4,500 ft²

2- getting the area of the isosceles triangle:

Area of triangle = 0.5 * base * height

From the drawing, we can note that:

base of triangle = height of triangle = smaller side of the rectangle = 45 ft

Therefore:

Area of triangle = 0.5 * 45 * 45 = 1,012.5 ft²

3- getting the total area:

Total area of parking lot = area of rectangle + 2*area of isosceles triangles

Total area of parking lot = 4500 + 2(1012.5)

Total area of parking lot = 6,525 ft²

Answer:

x is 12

Step-by-step explanation:

Write a proportion

4:5

x:15

or you can write it as 4/5=x/15

Cross multiply and you get 12  

The value of x if the scale factor of figure A to figure B is 4:5 is; x = 12

We are given the scale factor of figure A to figure B as 4:5.

Now, looking at both triangles, we can say that;

x:15 = 4:5

Thus,we can write in fraction as;

x/15 = 4/5

x = 15 × 4/5

x = 12

In conclusion, the value of x from the given proportion between both triangles is 12.

Step-by-step explanation:

First, you need to make these conversions:

(Remember that [tex]1m=100cm[/tex])

4,000 cm to m:

[tex](4,000cm)(\frac{1m}{100cm})=40m[/tex]

700 cm to m:

[tex](700cm)(\frac{1m}{100cm})=7m[/tex]

You can observe in the figure that it is formed by  two rectangles and a semi-circle.

To calculate the perimeter, you need to add the exterior measures of each figure.

Remember that the circumference of a circle is:

[tex]C=2\pi r[/tex]

Where "r" is the radius

Therefore, the perimeter is:

[tex]P=34m+7m+10m+40m+10m+68m+33m+\frac{(2\pi (17m)}{2}\\P=255.40m[/tex]

To find the area of the indoor sports exhibition, you need to add the areas of the rectangles and the area of the semi-circle.

The area of a rectangle can be calculated with:

[tex]A_r=lw[/tex]

Where "l" is the lenght and "w" is the width.

The area of a semi-circle can be calculated with:

[tex]A_{sc}=\frac{\pi r^2}{2}[/tex]

Where "r" is the radius.

Then, the area of the indoor sports exhibition  is:

[tex]A=(40m)(10m)+(68m)(33m)+\frac{\pi (17m)^2}{2}\\A=3,097.96m^2[/tex]

The perimeter of a square, if half of a diagonal is equal to 8 inches would be [tex]32\sqrt{2}[/tex] inches.

Where:

In Mathematics and Geometry, the side length of a square can be calculated by using this mathematical equation (formula);

Diagonal, d = √2s

d/2 = 8

d = 16 inches.

By solving for s, we have the following side length:

s = 16/√2

s = [tex]8\sqrt{2}[/tex] inches.

Now, we can determine the perimeter of the square is given by;

P = 4 × [tex]8\sqrt{2}[/tex] inches.

Answer:

A = choosing a red marble

B = choosing a green marble

Probability of A happening = P(A) = 5/(3+5+4) = 5/12

Probability of B happening = P(B) = 4/(3+5+4) = 4/12

Probability of either happening = P(A) + P(B) = 5/12 + 4/12 = 7/12

The key word in their question is red OR green and that is why we add the two probabilities. If they ask the probability of them both happening (if they said red AND green), you would multiply P(A)*P(B).

The probability that the chosen marble is not red is [tex]\frac{7}{12}[/tex].

A probability is a number that reflects the chance or likelihood that a particular event will occur.

The formula of the probability is

[tex]P(E) = \frac{Number\ of\ favorable\ outcomes}{Total\ number\ of\ outcomes }[/tex]

Where, P(E) is the probability of an event.

According to the given question.

Number of red marbles = 5

Number of blue marbles = 4

Number of green marbles = 3

So,

The total number of marbles in a bag = 5+4+3 = 12

And, the probability that chosen marble is red = [tex]\frac{5}{12}[/tex]

Therefore,

the probability that the chosen marble is not red

[tex]=1-\frac{5}{12} \\[/tex]

[tex]= \frac{12-5}{12}[/tex]

[tex]= \frac{7}{12}[/tex]

Hence, the probability that the chosen marble is not red is [tex]\frac{7}{12}[/tex].

Step-by-step explanation:

Answer:

See explanation

Step-by-step explanation:

Zeros of the function are those values of x, for which g(x)=0, so solve the equation g(x)=0:

[tex]x^3-x^2-4x+4=0\\ \\x^2(x-1)-4(x-1)=0\\ \\(x-1)(x^2-4)=0\\ \\(x-1)(x-2)(x+2)=0\\ \\x_1=-2,\ x_2=1,\ x_3=2[/tex]

Hence, the function has three zeros, x=-2, x=1 and x=2.

To find the y-intercept, substitute x=0:

[tex]y=g(0)=0^3-0^2-4\cdot 0+4=4,[/tex]

so y-intercept is at point (0,4).

The graph of the function shows that when x is infinitely small, then y is infinitely small too and if x is infinitely large, then y is infinitely large too.

Answer:

The zeros: x = 1, -2, 2

The y-intercept:  (0, 4)

The end behavior :

x  --> + ∞, f(x) --> + ∞

x  --> - ∞, f(x) --> - ∞

Step-by-step explanation:

Zero function:

x^3 - x^2 - 4x + 4 = 0

(x^3 - x^2) - (4x - 4) = 0

x^2(x - 1) - 4(x - 1) = 0

(x^2 - 4)(x - 1) = 0

(x + 2)(x - 2)(x - 1) = 0

x + 2 = 0; x = -2

x - 2 = 0; x = 2

x - 1 = 0; x = 1

The zeros: x = 1, -2, 2

The y-intercept when x = 0 so y-intercept = 4 or (0, 4)
