a scientists who studies insects enlarges a photograph of an elm leaf beetle every 2 inches in the photograph represents 8mm on the actual beetle the length of the beetle in the photograph is 1 1/2 inches .the width of the beetle in the photograph 3/4 inches what are the length and the
width of the actual beetle show your work
The length of the beetle is 6mm and the width is 3mm
A enlarged drawing is a drawing that is bigger than the original image / building / object
the enlarged drawing is usually increased at a constant dimension
Scale of the enlarged drawing = enlarged dimensions / original dimension
2 inches : 8 mm
1 : 4
So, 1 inch represents 4 millimetres
Length of the actual beetle = [tex]1\frac{1}{2}[/tex] x 4
= [tex]\frac{3}{2}[/tex] x 4 = 6mm
Width of the actual beetle = [tex]\frac{3}{4}[/tex] x 4 = 3mm

Each chef at "Sushi Emperor" prepares 15 regular rolls and 20 vegetarian rolls daily. On Tuesday, each customer ate 2 regular rolls and 3 vegetarian rolls. By the end of the day, 4 regular rolls and 1 vegetarian roll remained uneaten. How many chefs and customers were in "Sushi Emperor" on Tuesday?
9514 1404 393
Answer:
2 chefs13 customersStep-by-step explanation:
Let x and y represent the numbers of chefs and customers, respectively. We can write equations for the different kinds of rolls made and eaten:
15x -2y = 4 . . . . . 4 regular rolls were uneaten
20x -3y = 1 . . . . . 1 vegetarian roll was uneaten
Using the "cross multiplication method", the solution can be found to be ...
Δ1 = (15)(-3) -(20)(-2) = -5
Δ2 = (-2)(-1) -(-3)(-4) = -10
Δ3 = (-4)(20) -(-1)(15) = -65
1/Δ1 = x/Δ2 = y/Δ3, so we have ...
x = Δ2/Δ1 = -10/-5 = 2 . . . . there were 2 chefs
y = Δ3/Δ1 = -65/-5 = 13 . . . there were 13 customers

Additional comment
The version of the "cross multiplication method" I use for solving two linear equations is this. Write the equations in general form. List the coefficients in two rows, repeating the first column so there are 4 columns. Form "cross products" of the coefficients taking columns pairwise. Use these cross products to find the variable values.
In general form, these equations are ...
15x -2y -4 = 020x -3y -1 = 0Then the rows of coefficients are ...
[ 15, -2, -4, 15 ]
[ 20, -3, -1, 20 ]
The "cross multiplication" subtracts the product on the up-diagonal from the product on the down-diagonal. If we label the results Δ1, Δ2, Δ3, we get the results shown above. These "cross products" are used in the equation ...
1/Δ1 = x/Δ2 = y/Δ3
to find the values of x and y.
Some videos I have seen of this method write the two rows of coefficients shifted to the left, and use a different final equation for the solution. The result is the same. I find the extra shifting to make the process confusing and difficult to remember.
I prefer this method when there is no simple way to do substitution or elimination. In the end, it takes slightly fewer math operations than would be required by either of those methods in such cases.

Question 5: A car used 1164 gallon of gas to drive ya of a mile. At this rate, how many miles can the car travel using 1
gallon of gas?
I
Answer:
Hello! Your answer is BELOW
Step-by-step explanation:
Car will cover 16 miles in 1 gallon of the gas.
We can solve this question by unitary method.
∵ A car used [tex]\frac{1}{64}[/tex] gallons of gas to drive the distance = [tex]\frac{1}{4}[/tex] miles
∴ Car used 1 gallons to drive the distance = [tex]\frac{1}{4} \\\\\frac{1}{64}[/tex]
= [tex]\frac{64}{1} X \frac{1}{4}[/tex]
= [tex]\frac{64}{4}[/tex]
= 16 miles
Therefore, car will cover 16 miles in 1 gallon of the gas.

b.) Mark can run 5 blocks in 25 minutes. How many minutes does it take him to run 22 blocks?
Answer:
110 minutes or 1 hour and 50 minutes
Step-by-step explanation:
First, find out how long it takes Mark to run 1 block. You can find out how long it takes for him to run 1 block by dividing 5 from 25, which is 5. Then, multiply 5 times 22 because you are trying to find out how long it takes Mark to run 22 blocks. It takes Mark 110 minutes or 1 hour and 50 minutes to run 22 blocks.
Answer:
Mark can run 22 blocks in 110 minute
Step-by-step explanation:
Given
Blocks Time
5 25
22 (?)=x
now,
or, 5×x=25×22
or, 5x=550
or, x= 550/5
therefore, x= 110
Mark can run 22 blocks in 110 minute

Answer:
0.18 days
Step-by-step explanation:
There are 24 hours in a day, so to find out how many days are in x hours we need to divide x by 24.
x/24 = # of days
x - 4.3
4.3/24 = 0.179

9. Use Structure Point K is of the way from |(4,-5) to L(0, -7). a. What are the coordinates of Kif n = 4? b. What is a formula for the coordinates of K for any n?
Dividing the segments, it is found that:
a) The coordinates of K if n = 4 are [tex](5,-frac{9}{2})[/tex]b) [tex]K - J = \frac{1}{n}(J - L)[/tex]----------------------------
The endpoints are [tex]J(4,-5)[/tex] and [tex]L(0,-7)[/tex].Point K is (x,y).Since point K is [tex]\mathbf{\frac{1}{n}}[/tex] of the way from J to L, it means that:[tex]K - J = \frac{1}{n}(J - L)[/tex]
And this is the answer to option b.
----------------------------
Option a:
If [tex]\mathbf{n = 4}[/tex], it has that:
[tex]K - J = \frac{1}{4}(J - L)[/tex]
This is applied to find both the x-coordinate and the y-coordinate of K.
----------------------------
The x-coordinate of K is x.The x-coordinate of J is 4.The x-coordinate of L is 0.Thus:
[tex]K - J = \frac{1}{4}(J - L)[/tex]
[tex]x - 4 = \frac{1}{4}(4 - 0)[/tex]
[tex]x - 4 = 1[/tex]
[tex]x = 5[/tex]
----------------------------
The y-coordinate of K is y.The y-coordinate of J is -5.The y-coordinate of L is -7.Thus:
[tex]K - J = \frac{1}{4}(J - L)[/tex]
[tex]y - (-5) = \frac{1}{4}(-5 - (-7))[/tex]
[tex]y + 5 = \frac{2}{4}[/tex]
[tex]y = \frac{1}{2} - 5[/tex]
[tex]y = \frac{1}{2} - \frac{10}[2}[/tex]
[tex]y = -\frac{9}{2}[/tex]
The coordinates of K if n = 4 are [tex](5,-frac{9}{2})[/tex]

A translation of 2 units left means subtracting 2 from the x- coordinate
A translation of 4 units up means adding 4 to the y- coordinate
Z (3, 4 ) → Z' (3 - 2, 4 + 4 ) → Z' (1, 8 )

Answer: The length of LK is 40.
Step-by-step explanation:
LK = 6x+10
KM = 2x+8
LM = 58
so
LM = LK + KM
or, 58 = 6x+10+2x+8
or, 58 = 8x + 18
or, 58-18 = 8x
or, 8x = 40
so, x = 5
now
LK = 6x + 10
= 6*5+10
= 30 +10
= 40
