Ratios and Scale Worksheet #1. What does it mean when a map of a park says its scale is 1 to 50? #2. If a pathway in this same park is 7 inches long on the map, how many inches is it in real life? #3. How many feet will this same pathway be in real life? #4. A model car is built at a scale of 1 to 67. If the model car is 5 inches long, how many inches is the actual car? #5. How many feet will this same car be in real life? #6. A driver is driving at a constant speed and drives 9 miles. It takes her 10 minutes to drive this far. What is her speed in miles per hour? Help me please, thank you.
Answer:
1. This means that the actual park size is 50 times larger than the size of the park on the map.
2. If a pathway is 7 inches long on the map, it will be 50 times larger in real life;
= 7 * 50
= 350 inches
3. 1 foot is 12 inches so 350 inches will be;
= 350/12
= 29.2 feet
4. The real life length of the car is;
= 5 * 67
= 335 inches
5. The real life length in feet is;
= 335/12
= 27.9 feet
6. Speed = Distance / time
The time should be converted to hours;
= 10/60 minutes
= 1/6
Speed = 9 / (1/6)
= 54 miles per hour
= 54 mph
An ant crawls 14 cm down into an ant hole. It then crawls 6 cm up to the queens nest. What is the current location of the ant?
Answer:
8cm
Step-by-step explanation:
We subtract 14 from the location of the ant as it traverses down the hole
0 - 14
= -14
As the ant crawls up we at 6
-14 + 6
= -8
The answer would be 8 cm under elevation

3n + 7 - 2
Combing like terms
Answer:
Simplifying
3n + 7 + -2 = 0
Reorder the terms:
7 + -2 + 3n = 0
Combine like terms: 7 + -2 = 5
5 + 3n = 0
Solving
5 + 3n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-5' to each side of the equation.
5 + -5 + 3n = 0 + -5
Combine like terms: 5 + -5 = 0
0 + 3n = 0 + -5
3n = 0 + -5
Combine like terms: 0 + -5 = -5
3n = -5
Divide each side by '3'.
n = -1.666666667
Simplifying
n = -1.666666667

A circular coin has circumference 32 pi millimeters. Will the coin fit through a slot that is 35 millimeters long? Explain.
Answer:
Yes it will
Step-by-step explanation:
A circular coin has circumference 32 pi millimeters. Will the coin fit through a slot that is 35 millimeters long? Explain.
The formula for the circumference of a circle = πD
Where D = Diameter which can also be referred to as the length of the circle
Circumference =32π mm
Hence:
32π = πD
Cancel out the π
D = 32 mm
The diameter of the coin = 32 mm
The length of the slot = 35 mm hence, the coin with a diameter of 32 mm can fit into the slot
Find the solution for the system of linear equations by substitution: y = 3x + 4 and y = x + 2. Explain how
you found the solution.
Answer:
(-1, 1)
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations by substitution/eliminationStep-by-step explanation:
Step 1: Define systems
y = 3x + 4
y = x + 2
Step 2: Solve for x
Substitute: 3x + 4 = x + 2Subtract x on both sides: 2x + 4 = 2Subtract 4 on both sides: 2x = -2Divide both sides by 2: x = -1Step 3: Solve for y
Define: y = x + 2Substitute: y = -1 + 2Add: y = 1And we have our answer!

If the base of a triangle is 20mm and the area of the triangle is 40m2. then what will be the height and how can we find it
Use the formula for area of a triangle:
Area = 1/2 x base x height.
Fill in what you know:
40 = 1/2 x 20 x height
Multiply both sides by 2:
80 = 20 x height
Divide both sides by 20
Height = 4 m
Answer: 4 mm
Step-by-step explanation: this is because if you double the area then you will get the Area of 80 and if you divide it by 20 you will get 4 mm
PLEASE HELP ME! please!
Answer:
yes addison is right because using distributive property would get you from "5 (x + 1) - 2x = 2 (3 + x)" to "5x + 5 - 2x = 6 + 2x". from there, you'd combine like terms and simplify. you get "3x + 5 = 6 + 2x". Subtract 2x on each side, and you get "x + 5 = 6". Subtract 5 on each side, you get "x = 1".

hii, I would really appreciate it if you could help me out and answer this question. So this really isn’t a math question. You see I’m a 7th grader who got all A’s except for one C. I’m really worried that this C is going to affect me getting into a good high school especially since there going to be pay attention to my grades since we’re not taking the PSSA this year or any major tests. I also don’t know my gpa but at the bottom I’ll put my grades for the first marking period:
Health 7 - A (99.25%)
Mathematics 7 - A (99.75%)
Physical Education 7 - A (90.19%)
Reading 7 - A (98.14%)
Science 7 - A (100%)
Seminar - A (97.57%)

hi! i think you'll be ok, maybe ask your teacher if you can make up any work of do a project to get your grade up. teachers will more look at all you A's not that one C. :))
Step-by-step explanation:
Answer:
Hi!
Step-by-step explanation:
I think you will be okay! I calculated your average by adding all of them and dividing by the number of classes you are taking and it is still around a 96.5!! That is really good! If you are an overachiever like me, I understand that maybe you think it isn't your full potential, but trust me, it is a really good grade!! Whatever high school you are applying to (I'm not too sure how it works because I just went to my public highschool lol) will see you are taking a lot of classes and are doing phenomenal in all of them! I would try asking for extra credit or finding out if there is any way you can raise your grade, I do that when I am not happy with my grades. If you wanted to figure our your GPA out of 4.0 I think there are gpa calculators if you look them up. I hope this was helpful!
