Answer:
-11
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

five is 6 less than one third of a number
Answer:
The equation should be
n is used to represent a number.
1/3 is in fraction form
It also says 6 less than 1/2 of a number, so -6 should be after 1/3n. The operation happening between 1/3 and n is multiplication
Your final equation: 5=1/3n-6
Answer:
n = 33
Step-by-step explanation:
[tex]5=\frac{1}{3} n-6[/tex] ..... (1)
(1) × 3
15 = n - 18 ⇒ n = 33
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
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

a. Is the degree of the polynomial odd or even? Explain how you know.
b. What is the constant term of the polynomial?
9514 1404 393
Answer:
even-4Step-by-step explanation:
When the end behavior is the same sign on the left and the right, the degree is even. This polynomial is of even degree.
The y-intercept is the constant term: -4. (All the other terms are zero when x=0.)

Two circles are concentric. Let A be the area between the smaller circle and the larger circle. Let B be the area of the smaller circle. If A:B=3 and the radius of the smaller circle is 2020, what is the radius of the larger circle? (Do NOT include punctuation in your answer.)
Answer:
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

Answer: yes.
Step-by-step explanation: GCF.
Choose the representations or descriptions that model the relation provided in each item. For each relation, select all situations that apply.
x -2 0 2 4
f(x) 4 0 4 16
a The relation is a function.
b f( x) = -2 x
c f(4)= -2
d domain: {-2, 0, 2, 4}
e The relation is not a function.
f f( x) = x2
It is B and D because it is the only one that matches the input and outputs. D shows a perfect graph of the points while B shows the points themselves. They cannot be a linear function since they are not linear so it is not E or F.

Answer:
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.

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?
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

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 )

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
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.
