Which equation is modeled on the number line?

Answers
Answer:
Option D
Step-by-step explanation:
For addition we move right on the number line and for subtraction we move left.
So, (-7) represents a 7 units to the left from the zero.
Then move 10 units right from (-7),
Therefore, (-7) + 10 = 3
Or (-7) - (-10) = 3

A group of friends wants to go to the amusement park. They have $243.25 to spend on parking and admission. Parking is $15.75, and tickets cost $22.75 per person, including tax. How many people can go to the amusement park?
Answers
Answer: 10 people
Step-by-step explanation:
Parking needs to be paid for but if all friends are going together, they need to only pay once for parking.
The amount spent on just tickets is therefore:
= 243.25 - 15.75
= $227.50.
If $227.50 was for tickets alone, the number of tickets they could buy is:
= Total amount left/ Price of tickets
= 227.50 / 22.75
= 10 people

What is the approximate area of a circle with a diameter of 50 centimeters? Use π = 3.14 87.9 square centimeters 379.9 square centimeters 1962.5 square centimeters 4923.5 square centimeters
Answers
Answer:
144πfeets² ; 339.6 cm² ; 2461.8 cm² ; 1962.5 square centimeters
Step-by-step explanation:
Area of a circle, A = πr²
1.)
with a Radius of 12 feets
A = π * 12² = 144πfeets²
2.)
Approximate area :
3.14 * 10.4² = 339.6224 feet²
3.)
with a Radius of 28 cm
A = 3.14 * 28² = 2461.76cm²= 2461.8 cm²
4.
Diameter = 50 cm ; Radius = 50/2 = 25
with a Radius of 25 centimeter
A = 3.14 * 25² = 1962.5 cm²

b. What percent of the perimeter of the
square is the circumference of the
circle?
Answers
Answer:
Step-by-step explanation:
a. The diameter of the circle will be 30 cm
So circumference is 3.14 * 30 = 94.2 cm.
b. Required percentage = (94.2) * 100 / (4*30)
= 78.5%.
Find the slope of the line using the two given points.
(0, -2) and (3, 4)
Answers
Answer:
m = 2
Step-by-step explanation:
Using the slope formula, we can find the slope of two points:
y2 - y1
m = --------------
x2 - x1
The slope is the same thing as change in y over change in x. Now, plugging in the points (0, -2) and (3, 4):
4 - (-2) 4 + 2 6
m = ----------- = ------- = ------ = 2
3 - 0 3 3
So the slope is 2.

find the simple interest principle 950 interest rate 12% time 4 years
Answers
Answer:
A= $1406
Step-by-step explanation:
The formula for simple interest is A=P(1+rt), where P=Principal, R=Rate, and T=Time. Before you plug your numbers into your formula, you must first convert 12% to a decimal (This is simple because all you have to do is divide 12 by 100.)- 0.12.
Now, you can plug your numbers into the formula: A=950(1+0.12x4). To make this less complex, I suggest working in the parenthesis first- specifically simplifying rt, or multiplying 0.12 by 4 (you should get 0.48)! Now, you are just about ready to go. A=950(1+0.48)- You can plug this into your calculator as is, or you can go on ahead and add the numbers in the parenthesis if that makes you feel better! (You should get 1.48).
Your final formula should be 950(1.48), and you should plug this into a TEACHER-APPROVED CALCULATOR to save time!
Your final answer should be $1406, otherwise you did something wrong! XD!

The length and width of a rectangle are 1/6 inches and 3/8 inches. What is the perimeter (in inches) of the rectangle?
Answers
Answer:
1 1/12inches
Step-by-step explanation:
Given
Length = 1/6 inches
Width = 3/8 inches
Perimeter of the rectangle = 2 (Length + Width)
substitute
P = 2(1/6 + 3/8)
P = 2(4+9/24)
P= 2(13/24)
P = 26/24
P = 1 2/24
P = 1 1/12inches
hence the perimeter of the triangle is 1 1/12inches

what is the value of x and y?
Answers
Answer:
The right answer is x = 8, y = 40.
Step-by-step explanation:
Since this triangle is isosceles we know that...
∠ACB = ∠ABC
40° = (5x)°
40 = 5x
x = 40 / 5
x = 8
We also know that the sum of all angles inside the triangle is equal to 180°, therefore...
∠BAC = 180° - ∠ACB - ∠ABC
(2y + 20)° = 180° - 40° - 40°
2y + 20 = 100
2y = 100 - 20
2y = 80
y = 80 / 2
y = 40
From this, we know that the right answer is x = 8, y = 40.
