Step-by-step explanation:
Triangles have 180 degrees
using the vertical angle theory we know that 80 and 60 are angles
We can subtract them from 180 to get 40 left
this minus 51 is -11
x is -11

Answer : The shape of the fence will be a circle
dimensions of the fence are : radius = 6.5 meters
Step-by-step explanation:
First we calculate the length of the different arms
AB = [tex]\sqrt{(-2+6)^2 + (-3+1)^2}[/tex]
≈ 4.47
CD = [tex]\sqrt{(5-3)^2 + (0-4)^2}[/tex]
≈ 4.47
Next we calculate the midpoint of these two arms
M1 = [tex]( \frac{-6-2}{2} , \frac{-1-3}{2} )[/tex] = ( -4, -2 )
M2 = [tex]( \frac{3+5}{2} , \frac{0+4}{2} )[/tex] = ( 4,2 )
hence midpoint of M1,M2 =( M ) = ( 0,0 )
finally considering M calculate the distance between M and car B,D
MB = [tex]\sqrt{(0+2)^2 + (0+3)^2}[/tex] = 3.60
MD = [tex]\sqrt{(0-5)^2 + (0)^2}[/tex] = 5
therefore the radius of the fence will be
= 5 + 1.5 = 6.5 meters ( because MD > MB )

Circumference of circle 1 : Circumference of circle 2 = 1 : 2
Step-by-step explanation:
Circumference of a circle = πD, where D is the diameter.
Diameter of circle 1 = 1.125
Circumference of circle 1 = π x 1.125
Diameter of circle 1 = 2.25
Circumference of circle 1 = π x 2.25
Circumference of circle 1 : Circumference of circle 2 = 1 : 2

Which choice is the equation of the line that passes through the point (5, 19) and has a slope of
m=12 and is written in slope–intercept form?
Answers
Answer:
The equation is;
y = 12x-41
Step-by-step explanation:
Mathematically;
slope intercept form is;
y = mx + b
where m is slope and b is intercept
Since we already have the slope , the equation is;
y = 12x + b
To get b which is the y intercept, we simply substitute the value of the points given
Thus;
19 = 5(12) + b
19 = 60+ b
b = 19-60
b = -41
So the equation is;
y = 12x - 41

Beetle cellular offers cellular phone service for 39.95 a month plus one cent a minute. Salamander digital offers cellular phone service for 9.95 a month plus five cents a minute. How many minutes would a person need to use a month for beetle cellular to cost the same as salamander digital
Answers
Answer:
750 minutes
Step-by-step explanation:
Let the number of minutes be represented as x
1 cent = 0.01
Beetle cellular offers cellular phone service for 39.95 a month plus one cent a minute.
$39.95 + 0.01x
Salamander digital offers cellular phone service for 9.95 a month plus five cents a minute.
$9.95 + 0.05x
How many minutes would a person need to use a month for beetle cellular to cost the same as salamander digital?
This is calculated as:
Beetle cellular = Salamander digital
$39.95 + 0.01x = $9.95 + 0.05x
Collect like terms
$39.95 - $9.95 = 0.05x - 0.01x
$30.00 = 0.04x
x = $30.00/0.04
x = 750 minutes
A person need to use 750 minutes a month for beetle cellular to cost the same as salamander digital.

The second option, 2 is a prime number, but not odd
Step-by-step explanation:
A prime number is a result of two other whole numbers multiplied by themselves. There is no whole number that you can multipy by itself to get 2 because 1 × 1 = 1 and 2 × 2 = 4. Therefore, it is a prime number. But, that does not mean it is an odd number because odd numbers are 1, 3, 5, 7, etc. and even numbers are 2, 4, 6, 8, etc.

The number of boys and girls in a class are in the ratio 4 : 7. There are 15 more girls than boys. find the number of total students in the class
Answers
Answer:
The number of total students in the class is 55
Step-by-step explanation:
We will use the ratio method to solve the question
∵ The number of boys and girls in a class are in the ratio 4: 7
∵ There are 15 more girls than boys
→ That means the difference between them is 15
∵ The difference between the terms of their ratio = 7 - 4 = 3
→ By using the ratio method
→ boy : girl : difference
→ 4 : 7 : 3
→ x : y : 15
→ By using cross multiplication
∵ x × 3 = 4 × 15
∴ 3x = 60
→ Divide both sides by 3
∴ x = 20
∵ y × 3 = 7 × 15
∴ 3y = 105
→ Divide both sides by 3
∴ y = 35
∵ x represents the number of boys
∴ The number of boys is 20
∵ y represents the number of girls
∴ The number of girls is 35
∴ The total number of students = 20 + 35 = 55
∴ The number of total students in the class is 55
