The scale factor of a model car to the actual car is 300. If the model car is 2in tall, how tall is the actual car?
Answer:
600 inches or 50 feet
Step-by-step explanation:
Scale factor = model car : actual car = 1 : 300
We have a 2 inch model car.

Answer :[tex] \displaystyle \blue{\boxed{\green{\bold{v = 8}}}} [/tex]
[tex] \\ [/tex]
Explanation:-5v + 6 = -12v + 62
[tex] \\ [/tex]
▪️Subtract 6 from both sides :
-5v + 6 - 6 = -12v + 62 - 6
-5v = -12v + 56
▪️Add 12v to each side :
-5v + 12v = -12v + 56 + 12v
7v = 56
▪️ Divide both sides by 7 :
7v / 7 = 56 / 7
v = 8

Therefore, our answer is v = 8.

Answer:
v = 8
Step-by-step explanation:
Hello!
We can solve the equation by moving all terms of V to one side, and all integer values to the other.
Solve-5v + 6 = -12v + 62-5v + 6 + 12v = -12v + 62 + 12v7v + 6 = 627v + 6 - 6 = 62 - 67v = 56v = 56/7v = 8The value of v is 8.
We can plug back 8 into the original to check our answer:
-5(8) + 6 = -12(8) + 62-40 + 6 = -96 + 62-34 = -34Since both sides match, the solution of v = 8 is correct.

Area = 3430
Step-by-step explanation:
Graphing y = 28x - x^2 with it's limit interval (0<x<28). They ask for four sub-interval of LRAM.
Divide the base of 28 into 4 equal rectangles.
Area = (Base * Height) + (Base * Height) + (Base * Height) + (Base * Height)
Area = (0 * 7) + (147 * 7) + (196 * 7) + (147 * 7)

A snail crawls 83 cm due west and then
78 cm due north.
Work out the bearing of the snail from its
starting point.
Give your answer to the nearest degree.
Answer:
313°
Step-by-step explanation:
The reference angle (α) can be found using the tangent relation:
Tan = Opposite/Adjacent
__
In this problem, that means ...
tan(α) = 78/83
α = arctan(78/83) ≈ 43° . . . . . . angle from -x axis
The bearing angle will be this value added to 270°, since bearing angles are measured clockwise from north.
bearing = 270° +43° = 313°
A teacher bought 8 books at (p - 1500) each book and 2 pens at (p + 1000) each pen. If the teacher spent 53,000 altogether, how much money did he spend on the books?
Answer:
38400/=
Step-by-step explanation:
8(p-1500)=8p-12000
2(p+1000)= 2p+2000
8p-12000+2p+2000=53000
10p-10000=53000
10p=53000+10000
10p=63000
p=6300/=
8 books=8(6300-1500)

A fabric store is having a sale. The price of every item in the store has been reduced by 30%. Which equation shows the
proportional relationship between the regular price, r, of an item and its sale price, s?
Equation to show the proportional relationship between the regular price, r, of an item and its sale price, s is 10s -7r=0.
What is sale price?A sale price is the discounted price at which goods or services are being sold. This price is usually offered for a limited period of time, typically to spur sales during a slow period or to sell off excess inventory.
Let the regular price be r and sale price be 's'
Since price of every item reduced by 30%.
So, sale price will be
[tex]s= r- 30% of r[/tex]% of r
[tex]s= r- \frac{30}{100} *r[/tex]
s= r - 0.3 r
s= 0.7 r
s-0.7r=0
or, 10s -7r=0
Thus, equation shows the proportional relationship between the regular price, r, of an item and its sale price, s :10s -7r=0

How many integers from 1 to 100 have a factor of 3?
Answer: 33 integers
Step-by-step explanation:
The numbers with a factor of 3 must be a multiple of 3. Therefore, since 99 is the greatest multiple of 3 that is less than 100, we can divide 99 by 3 to get 33 integers (for every 3 consecutive integers, there is one multiple of 3). We can also divide 100 by 3 to get 33 1/3, which rounds to 33 integers.
