The animal is 150 inches tall .
Scale Factor = ( scale / actual )
Given : Scale Factor = ( 1 / 30 )
To find : the actual height of animal .
Let t be the actual height of animal .
Therefore Scale Factor comes out to be ( 5 / t ) .
Equating both the scale factors and hence finding the value of t ,
( 1 / 30 ) = ( 5 / t )
t = 150 inches .
Therefore , the animal is 150 inches tall .

Una empresa tiene costos fijos de $300 y vende cada artículo en $15. Si se sabe que el punto de equilibrio es q=100. Plantear la función de Costos Totales
CT=__________________________
Based on the fixed costs and the equilibrium point, the function for total costs would be TC = 300 + 100VC
What s the function for total cost?The total cost that a company incurs for making a good or service is a combination of both the fixed cost and the variable cost.
The total variable cost is found as:
= Number of units produced x variable cost per unit
= 100 units x vc
= 100vc
The total cost would therefore be:
= Fixed cost + Total variable cost
= 300 + 100vc

Miles has a square garden in his backyard. He decides to decrease the size of the garden by 1 foot on each side in order to make a gravel border. After he completes his gravel border, the area of the new garden is 25 feet2. In the equation (x - 1)2 = 25, x represents the side measure of the original garden.
The length of each side of the original garden was
feet.
The area of the original garden was
feet2.
The original garden was 6 feet long on each side. The original garden's footprint measured 36 feet.
How would you define Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies. Consider your square as being composed of smaller unit squares.
Using the information provided,
(x-1)²=25
(x-1)=5
x=6
6x6=36 feet²
The original garden had six sides that were the same length.

Step-by-step explanation:
Two towns are 52 km apart. Buses travelling
between the two towns leave at the same
time but travel in opposite directions. The
bus from town A is travelling 80 km/h and
the bus from town B is travelling 70 km/h.
How long after they leave will they pass each
other? (Reminder: there are 60 minutes in an
hour!)
Step-by-step explanation:
x = number of km bus from A drives until they meet.
y = number of km bus from B drives until they meet.
x/80 is the time for the bus from A to reach the meeting point.
x/70 is the time for the bus from B to reach the meeting point.
both times must be equal, as they start at the same time.
so,
x/80 = y/70
but then we also know that together they have traveled the full 52 km to meet.
so,
x + y = 52
x = 52 - y
with that we go into the first equation :
(52 - y)/80 = y/70
(52 - y)/8 = y/7
7×(52 - y)/8 = y
7×(52 - y) = 8y
364 - 7y = 8y
364 = 15y
y = 364/15 km = 24.26666666... km
x = 52 - y = (780-364)/15 = 416/15 = 27.73333333... km
they will meet after (using bus from B)
364/15 / 70/1 = 364/1050 hours
= 182/525 hours =
= 60×182/525 = 10920/525 minutes =
= 728/35 = 104/5 = 20.8 minutes =
= 20 minutes 60×8/10 seconds =
= 20 minutes 48 seconds
control (using bus from A) :
416/15 / 80/1 = 416/1200 hours =
= 26/75 hours =
= 60×26/75 = 1560/75 minutes =
= 104/5 = 20.8 minutes

Write the slope-intercept form equation of the line that passes through the points (1,−6) and (9,−5).
Complete the equation in the space below (do not enter "y = ").
Answer:
Step-by-step explanation:
Point slope form y-y₁ = m(x-x₁)
-5 - (-6) = m(9 - 1)
1 = m(8)
1/8 = m
y= 1/8x + b
-6 = 1/8(1) + b
b = -6.125
y = 1/8x -6.125
(30 POINTS) A construction worker is pouring concrete stairs. The first step requires 1.7 cubic feet of concrete, and the first 4 steps require a total of 17 cubic feet. If the steps follow an arithmetic series, how much concrete is required for the first 12 steps?
51 cubic feet
93.5 cubic feet
132.6 cubic feet
244.8 cubic feet
The volume of concrete required for the first 12 steps is 132.6 cubic feet
Given data
the first step requires 1.7 cubic feet of concrete
the first 4 steps require a total of 17 cubic feet
How to solve for the first 12 stepsthe first term = a = 1.7
4th step = n/2 ( 2a + ( n - 1 ) d )
d is common difference
n = number of terms
17 = 4/2 ( 2*1.7 + ( 4 - 1 ) d )
17 = 2( 3.4 + 3d )
8.5 = 3.4 + 3d
5.1 = 3d
3d = 5.1
d = 1.7
sum of AP at 12th step
12th = n/2 ( 2a + ( n - 1 ) d )
12th = 6( 2 * 1.7 + ( 12 - 1 ) * 1.7)
12th = 6 (3.4 + 11 * 1.7)
12th = 6 * 22.1

Chapter 1 Workbook
The rate of commission for a commission of $5040 on total sales of $180700 nearest to tenth percent will be 2.8 %.
What is commission rate ?
The commission rate is the percentage or fixed payment associated with a certain amount of sale.
It is given that , Myrtle Gould's total sales last month were of $180700. And the commission she got for the sales was $5040.
Here , the sale is above the criteria to get the commission which is $50000.
The rate of commission can be calculated as follows :
Rate of commission (R) = (5040 × 100) / 180700
or
R = 504000 / 180700
or
R = 2.8 %
or
Rate of commission will be 2.8 %.
Therefore , the rate of commission nearest to tenth percent will be 2.8 %.

Point J is on line segment I K ‾ IK . Given J K = 10 JK=10 and I K = 19 , IK=19, determine the length I J ‾ . IJ
The length of the line segment IJ is 9.
What is the length of a line segment?
In this question we find that the line segments IJ and JK are collinear, that is, part of one same line. By Euclidean geometry and algebra, we construct the following formula:
IK = IJ + JK
IJ = IK - JK
If we know that IK = 19 and JK = 10, then the length of the missing line segment is:
IJ = 19 - 10
IJ = 9
The length of the line segment IJ is 9.
