Answer:
1:180
Step-by-step explanation:
We start by multiplying the 120 feet by 12 inches to get the height of the building in inches, which is 1440.
Then, we have a ratio of 8:1440, which simplifies to 1:180 when we divide 1440 by 8.
The required scale factor of the given model is 1/180.
What is a scale image?Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.
A building scale model is 8 inches tall. The original structure stands 120 feet tall.
Here 1 foot is equal to twelve inches which is given in the question.
As per the given situation, the required solution would be as :
Firstly we have to multiply 120 feet by 12 inches to obtain the building's height in inches, which is 1440.
The result is an 8/1440 ratio, which simplifies to 1/180 when 1440 is divided by 8.
Therefore, the required scale factor of the given model is 1/180.

what is the slope of this graph?
Answer:
Slope = -1
Step-by-step explanation:
Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of a line passing through two points A(1, 4) and B(3, 2) will be,
Slope = [tex]\frac{4-2}{1-3}[/tex]
= (-1)
Therefore, slope of the line is (-1).
A can of juice is 6 inches high, and its base has a diameter of 4 inches. What is the volume of the can
Answer:
73.36
Step-by-step explanation:
A can of juice is 6 inches high
The diameter is 4
Radius= 4/2
= 2
Hence the volume of the can (cylinder,) can be calculated as follows
= πr^2h
= 3.142× 2^2 × 6
= 73.36 inches
Work out the percentage change when a price of £10 is increased to £14
Answer:
hmmm well.
Step-by-step explanation:
they added £4
Answer:
40%
Step-by-step explanation:
The formula for percentage change is given by:
[tex]\boxed{\text{Percentage change}=\frac{\text{New}-\text{Original}}{\text{Original}}\times100\% }[/tex]
In this case, the original price is £10 while the new price is £14.
Substitute the values into the formula:

-5 = 1/7a
Answer:
-35
Step-by-step explanation:
[tex]-5 = \frac{1}{7}a\\-35 = a[/tex]
I got this by multiplying the numerator by 7. This allows the denominator to be the same as the numerator, thus equalling 1.
1 * a = a
Answer: a = -35
Step-by-step explanation:
1. -5 = 1/7(a) || GIVEN
2. -5 * (7) = (7) * 1/7(a) || Isolate "a" on one side of the equation by multiplying 7 to the other side.
3. -35 = a

June uses 12 eggs to make cupcakes. She uses four eggs for each batch of cupcakes. Which expressions can be used to find the number of batches she makes?
Answer:
3 batches
Step-by-step explanation:
Given that :
Let Number of batches of cupcakes made = x
12 eggs was used to make x batches
Number of eggs used per batch = 4
If 4 eggs was used for a batch :
Number of batches of cupcakes made :
12 eggs / 4 eggs
= 3 batches

X=49°
Step-by-step explanation:
we have an isosceles triangle
thus our equation is
x+x+82=180°
=>2x+82°=180°
cancel 82 from both sides
=>2x=98
divide both sides by 2
therefore
X=49

A. 65
B.
40
C.
25
D.
50"
Answer:
C. 25°
Step-by-step explanation:
A useful relation for this geometry is "an exterior angle of a triangle is equal to the sum of the remote interior angles." The measure of arc BC is the same as the measure of central angle BDC, which is an exterior angle of triangle ACD.
__
Triangle ACD has sides AD and CD that are radii of the circle, so it is an isosceles triangle with angle A ≅ angle C. Exterior angle BDC is the sum of those congruent angles:
∠BDC = ∠CAD +∠ACD
50° = 2×∠ACD
25° = ∠ACD . . . . . . . . divide by 2

For the polynomial, list each real zero and its multiplicity. Determine whether the graph
crosses or touches the x-axis at each x -intercept.
f(x) = 3(x + 7)(x + 3)^2?
A? B? C? D?
Answer:
B
Step-by-step explanation:
You find the multiplicity by looking at the power of the original root. You can imagine it as [tex](x+7)^1(x+3)^2[/tex]. Now set those equal to 0 to find the value of them as roots.
[tex]x+7=0\\x+3=0[/tex]
Solve them both and you get:
[tex]x=-7\\x=-3[/tex]
Now as we saw in the origin of the roots above that (x + 7) was raised to the first power. That means it has a multiplicity of one, which also means it crosses when it reaches the x-axis. (x + 3) however had a multiplicity of 2, since it was squared. That means that (x + 3) will touch and turn the x-axis.
Therefore the answer is B since that agrees with everything we said.
On a hospital floor, 16 patients have a disease with a mortality rate of 0.1. Find the probability that two of them die. Round to three decimal places
Answer:
The probability that two of them
die is 0.257
Step-by-step explanation:
From the question, we have that the mortality rate is 0.1
So the probability that they will survive is 1-0.1 = 0.9
Now, we want to check that two will die
We are going you use the Bernoulli approximation of the Binomial theorem as follows
= nCr * p^n * q^(n-r)
where n = 16
r = 2
P = 0.1
q = 0.9
Substituting these values;
14 C 2 * 0.1^2 * 0.9^12
= 0.257
In if GS ⊥ XJ and XJ⊥EA what is true about GS and EA
Answer:
([tex]GS[/tex]) || ([tex]EA[/tex])
Step-by-step explanation:
When two lines are parallel, all four angles formed by the intersection of the two lines are right angles, meaning their angle measures are (90°). This means that alternate interior angles are congruent because all alternate interior angles measures equal (90°). Therefore, by the alternate interior angles converse theorem, lines ([tex]GS[/tex]) and ([tex]EA[/tex]) are parallel.
The alternate interior angles converse theorem states if two angles are congruent and they have the relation of being a part of two lines intersected by a third line, then the two non-intersecting lines are parallel.

6. How far is it from the point (-5, 7) to the point (6,-2)? Round your answer to the nearest tenth.
Answer:
14.2 units
Step-by-step explanation:
Here x increases by 11 from -5 to +6. This is the length of the horizontal leg of a right triangle. Then y decreases by 9 from 7 to -2. This is the length of the vertical leg. The hypotenuse of this triangle may be found using the Pythagorean Theorem:
11^2 + 9^2 = (hypotenuse)^2, or
hypotenuse = √(121 + 81) = √202 ≈ 14.2 units
Answer:
≈ 14.2
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 5, 7) and (x₂, y₂ ) = (6, - 2)
d = [tex]\sqrt{(6+5)^2+(-2-7)^2}[/tex]
= [tex]\sqrt{11^2+(-9)^2}[/tex]
= [tex]\sqrt{121+81}[/tex]
= [tex]\sqrt{202}[/tex]
