Answer:
15 inches
Step-by-step explanation:
12 inches = 1ft
12ft = 144 inches
144/9 = 16
20ft = 240 inches
240/16 = 15 inches
Tom wants the scale model to be 9 inches tall, the width of the scale model should be 15 inches.
What is scale model?A scale model is a physical representation of an object that maintains the proportions and relative sizes of the original object.
First, we need to determine the scale factor that will be used to create the model.
We can do this by converting the height of the real garage from feet to inches and dividing it by the desired height of the model in inches:
12 feet = 12 x 12 = 144 inches
scale factor = 144 / 9 = 16
This means that every dimension of the model will be 16 times smaller than the actual dimensions of the garage.
To find the width of the scale model, we need to take the actual width of the garage and divide it by the scale factor:
20 feet = 20 x 12 = 240 inches
240 / 16 = 15 inches
Thus, the width of the scale model should be 15 inches.

PLZZZZZZ HELP ME
Step-by-step explanation:
The coordinate plane is a two-dimension surface formed by two number lines. One number line is horizontal and is called the x-axis. The other number line is vertical number line and is called the y-axis. The two axes meet at a point called the origin. We can use the coordinate plane to graph points, lines

Little billy wants to buy a pineapple upside down came. The cakes are 2 days old so they are 70% off! The original price is $20. What is the sale price
Answer:
$6
Step-by-step explanation:
Original price of the pineapple = $20
Percentage off = 70%
Amount discounted = 70% of $20
Amount discounted = 0.7 * 20
Amount discounted = $14
Sale price = Original price - Discount
Sale price = $20 - $14
Sale price = $6
Hence the sale price was $6

A man sold a fan for Rs. 400. Find the cost price if he incurred a loss of 15%.
Answer:
Cost price of the fan is [tex]\text {Rs. 470.59}[/tex].
Step-by-step explanation:
Given: A man sold a fan for [tex]\text{Rs.}\:400[/tex]. He incurred a loss of [tex]15\%[/tex].
To find: The cost price of the fan
Solution:
We have,
Selling price, S.P., of the fan [tex]= \text{Rs.} 400[/tex]
Loss [tex]=15\%[/tex]
We know that [tex]\text {Loss\%}=\frac{\text{C.P.-S.P.}}{\text{C.P.}}\times100\%[/tex]
Now let the C.P. of the fan be [tex]\text{Rs.} \:x[/tex]
So, [tex]15=(\frac{x-400}{x})\times 100[/tex]
[tex]\implies 15x=100x-40000[/tex]
[tex]\implies 100x-15x=40000[/tex]
[tex]\implies 85x=40000[/tex]
[tex]\implies x=\frac{40000}{85}[/tex]
[tex]\implies x= 470.59[/tex]
Hence, the cost price of the fan is [tex]\text {Rs. 470.59}[/tex].

Discriminate
Answer:
D = 41
Step-by-step explanation:
y = ax² + bx + c
The discriminant D = b² - 4ac tells the types of roots the equation has.
If D < 0 , then quadratic equation has no real roots, has two imaginary roots.
If D = 0 , then quadratic equation has one real root.
If D > 0 , then quadratic equation has two distinct real roots.

x² + 5x - 4
a = 1, b = 5, c = - 4
D = 5² - 4(1)(- 4) = 25 + 16 = 41

Write an equation of the line in slope intercept form
Answer: y = x + 2 OR f(x) = x + 2
Step-by-step explanation:
Calculating slope:
Remember rise over run; when going from one point to another point, in this case from (-3, -1) to (0,2), locate the distance moved in the x and y directions. This scenario moves 3 up and 3 right, meaning a positive slope of one. However, if the line was directed left, your slope would be negative.
Finding y-intercept:
Where does the line intersect the y-axis and have a x-value of 0? This is your y-intercept --> (0,2).
Write Equation:
y = mx +b
y = 1x + 2
y = x + 2 (your final answer)

Clara found the product of 3 – 6y2 and y2 + 2. Her work is shown below.
(3 – 6y2)(y2 + 2) = 3(y2) + (–6y2)(2)
= 3y2 – 12y2
= –9y2
Is the student’s work correct?
Answer: No the students work is not correct. Because you are using distribution. Which means that 3 has to multiply the y2 and 2 not just the y2! And after you distribute it you need to simplify!
Step-by-step explanation:
Answer:
(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6
Step-by-step explanation:
Given the expression
3-6y² and y²+2
We have to find the product of 3-6y² and y²+2
Clara's Solution:
(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2)
= 3y² – 12y²
= -9y²
NO!
The student's work is INCORRECT!
Clara did not imply the correct distribution of multiplying the terms in the first step.
Here is the correct solution:
(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2) + (3)(2) + (–6y²)(y²)
= 3y² – 12y² + 6 - 6y⁴
= - 6y⁴ - 9y² + 6
Therefore,
(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6

The figure below depicts a triangle formed by the labeled
vertices. If each vertex point of the triangle is multiplied
by what would be the area of the resulting triangle?
(Triangles, Book 2)
(3, 3)
0.0)
09
0 13.5
0 15
18
O 27
9514 1404 393
Answer:
(b) 13.5
Step-by-step explanation:
The upper vertex would be ...
3/2(3, 3) = (4.5, 4.5)
and the right vertex would be ...
3/2(4, 0) = (6, 0).
The base of the larger triangle would be 6, and its height would be 4.5. Then the area is ...
A = (1/2)bh
A = (1/2)(6)(4.5) = 13.5 . . . area of dilated triangle

An airplane descends 1.5 miles to an elevation of 6.05.Find the elevation of the plane befor its descent the intial elevation of the plane was blank miles
Answer:
7.55 miles
Step-by-step explanation:
Given that :
Distance of descent = 1.5 miles
New elevation point after descent = 6.05 miles
The initial elevation of the plane before descent will be :
New elevation point after descent + Distance of descent
(6.05 miles + 1.5 miles)
= 7.55 miles
