Can someone help me with this please ??

Answer: 207 degrees

Step-by-step explanation:

Since a circle is 360 degrees,

103+50+35+27 = 215, 360-215=145

Add ED and BC to 145 to get - 207

The rate of the passenger train must be 45 miles per hour, and the rate of the freight train must be 30 miles per hour.

Let's denote the rate of the passenger train as "P" and the rate of the freight train as "F". We are given that the passenger train's rate exceeds the freight train's rate by 15 miles per hour. Therefore, we can write the following equation:

P = F + 15

We are also given that the two trains start from points that are 300 miles apart and meet after 4 hours. We can use the formula distance = rate × time to set up two equations:

Distance covered by the passenger train: P × 4

Distance covered by the freight train: F × 4

Since they meet each other, the sum of their distances should add up to 300 miles:

P × 4 + F × 4 = 300

Substituting P = F + 15 into the equation, we can solve for F:

(F + 15) × 4 + F × 4 = 300

4F + 60 + 4F = 300

8F = 240

F = 30

Now that we have the rate of the freight train, we can substitute it back into the equation P = F + 15 to find the rate of the passenger train:

P = 30 + 15

P = 45

Therefore, the rate of the passenger train must be 45 miles per hour, and the rate of the freight train must be 30 miles per hour.

Answer:

Option (2). 1

Step-by-step explanation:

Coordinates of point A, B, C and D are,

A(-4, 4), B(-2, 4), C(-2, 1) and D(-4, 3).

Quadrilateral ABCD when rotated 90° clockwise about the origin,

Rule for the rotation of the vertices,

(x, y) → (y, -x)

Following the rule of rotation coordinates of the image points,

A(-4, 4) → A'(4, 4)

B(-2, 4) → B'(4, 2)

C(-2, 1) → C'(1, 2)

D(-4, 3) → D'(3, 4)

Since all image points have the positive coordinates (x and y coordinates), image quadrilateral A'B'C'D' will be located in 1st quadrant.

Option (2) is the correct option.

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

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (0,-2) and (2,2)

[tex]=\frac{2-(-2)}{2-0}\\=\frac{2+2}{2}\\=\frac{4}{2}\\=2[/tex]

Therefore, the slope of the line is 2. Plug this into [tex]y=mx+b[/tex] as m:

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

2) Determine the y-intercept (b)

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

Plug in one of the given points and solve for b

[tex]2=2(2)+b\\2=4+b[/tex]

Subtract 4 from both sides to isolate b

[tex]2-4=4+b-4\\-2=b[/tex]

Therefore, the y-intercept of the line is -2. Plug this back into [tex]y=2x+b[/tex]

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

Answer:

FV= $2,571.41

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $1,500

Interest rate (i)= 0.045/12= 0.00375

Number of periods (n)= 12*12= 144 months

To calculate the future value, we need to use the following formula:

FV= PV*(1 + i)^n

FV= 1,500*(1.00375^144)

FV= $2,571.41

Answer:

9.82 inches²

Step-by-step explanation:

both areas are equally sized, so they are both half of the whole circle.

circle area : pi × r²

half of the circle area is therefore pi × r² / 2

the picture gives us the diameter of the circle, the radius is half of the diameter.

=> r = 5/2 = 2.5

=> shaded area = pi × r² / 2 = pi × (2.5)² / 2 = 9.82 inches²

Answer:

First blank - A)Total Number of Possible Outcomes

Second blank - B)Number of Winners

Step-by-step explanation:

The exact question is as follows :

We know that,

Probability of an event is equals to Total number of Favorable outcomes divided by Total number of outcomes

So,

P(event) = Number of favorable outcomes ÷ Total Number of Possible Outcomes

As we have to predict the Number of winners of a game

So,

P(Number of winner) = Number of winners ÷ Total number of Contestants

∴ we get

P(event) = Number of favorable outcomes ÷ Total Number of Possible  Outcomes

             = Number of winners ÷ Total number of Contestants
