Josephine enlarged a picture using a photocopier the original photo was 3.5 inches by 5 inches the copy was 8.5 by 12.5 inches . What is the scale factor of the dilation?
Answer:
the answer is 1 : 2.4 because for every 1 inch on the original image there are 2.4 inches on the modified image.
Step-by-step explanation:
Step 1:
Measure the change in X and Y of a single length of the original image.
X1 = 3.5
Y1 = 5
Step 2:
Measure the change in X and Y of the same length on the modified image.
X2 = 8.5
Y2 = 12.5
Step 3:
use formula SF = X2/X1 = Y2/Y1
(SF = Scale Factor Dilation)
(X2 and Y2 = change in X and Y of the same length on the modified image.)
(X1 and Y1 = change in X and Y of a single length of the original image.)
X2 = 8.5
8.5/X1
X1 = 3.5
8.5/3.5
8.5/3.5 = 2.4
2.4
1 : 2.4

-10+7/4p=-38
Show your work in details if you can, I have a hard time understanding this.
Answer:
Here is your answer . Hope it helps you
Answer:
p = -49
Step-by-step explanation:
-10 + 7/4p = -38
+7/4 p = -38 + 10. ..........(-10 taken to other side)
+7/4 p = -28
p = -28 × 7/4 ........( now taken 7/4 to other side)
p = -196/4 .......(here we have multiplied . (-28×7 )
p = -196/4
p = -49
so p = -49

A farmer notes that in a field full of horses and geese there are 30 heads and 84 feet. How many of each animal are there?
Answer:
There are 12 horses and 18 geese.
Step-by-step explanation:
We are given that in a field full of horses and geese, a farmer notes that there are 30 heads and 84 feet.
We can write a system of equations using the given information.
Let the amount of horses there are be represented by h and geese by g.
Assuming each horse and geese has only one head, we can write that:
[tex]\displaystyle h + g= 30[/tex]
And assuming that each horse has four feet and each geese has two feet, we can write that:
[tex]4h + 2g = 84[/tex]
This yields a system of equations:
[tex]\displaystyle \left\{\begin{array}{l} h + g = 30 \\ 4h + 2g = 84 \end{array}[/tex]
We can solve it using substitution. From the first equation, isolate either variable:
[tex]g = 30 - h[/tex]
From the second, we can first divide by two:
[tex]2h + g = 42[/tex]
And substitute:
[tex]2h + (30 - h) = 42[/tex]
Combine like terms:
[tex]h + 30 = 42[/tex]
Subtract:
[tex]h = 12[/tex]
Therefore, there are 12 horses.
And since the total number of animals is 30, there must be 30 - 12 or 18 geese.
In conclusion, there are 12 horses and 18 geese.

Determine the perimeter of the shape to the nearest centimeter. (Picture included)
Answer:
44 cm
Step-by-step explanation:
So we know that the bottom 12 is congruent to to the line at the top, so that is also 12. And the 5 is congruent to the other 3 lines with one hash mark going through it. So perimeter is the sum of all the side lengths on a polygon. So we have 12+12+5+5+5+5=44.

The formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid is p = s + dgh, where s is the atmospheric pressure, d is the density of the liquid, and g is the acceleration due to gravity.
(Pls Explain the Answer in simple terms)
Answer:
The formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid is p = s + dgh
[tex]p(pressure) = s(atmospheric \: pressure) + d(density \: of \: the \: liquid)g(acceleration \: due \: to \: gravity)h[/tex]
Step-by-step explanation:
where s is the atmospheric pressure, d is the density of the liquid and g is the acceleration due to gravity.
solve for x of the given angle
Answer:
m<ABC = 92
Step-by-step explanation:
(3x + 23) and 4x are equal angle wise. So we have the equation:
(3x + 23) = 4x
3x = 4x - 23
-x = -23
x = 23
Multiply x by 4 which is 92
Checkered Cab Taxi charges a $ 5.95 flat rate for a ride in the cab. In addition to that, they charge $ 0.25 per mile. Katie has no more than $ 20 to spend on a ride. At most, how many miles can Katie travel without exceeding her spending limit?
Answer: 56.2 miles
Step-by-step explanation:
5.95+0-25x less or equal 20
0.25x less or equal 20 - 5.95
0.25x less or equal 14.05
X less or equal 14.05/0.25
X = 56.2
Katie can travel at most 56.2 miles in $20.
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions is called inequality.
According to the given question.
The total money Katie have = $20.
Amount charged by cab taxi for ride = $5.95
Charges for per mile ride = $0.25
Let Katie travel x miles without exceeding her expending limit.
From the given condition we get a inequality
[tex]20\geq 5.95+0.25x[/tex]
Solve the above inequality for x.
⇒[tex]20 - 5.95\geq 0.25x[/tex]
⇒ [tex]14.05\geq 0.25x[/tex]
⇒[tex]x\leq \frac{14.05}{0.25}[/tex]
⇒[tex]x\leq 56.2miles[/tex]
Katie can travel at most 56.2 miles in $20.

after allowing 20percent discount and levying 13percent vat the value of a watch will be rs 904 what is the marked price of watch
9514 1404 393
Answer:
₹1000
Step-by-step explanation:
Let m represent the marked price. After the discount, the price is 0.80m. After the tax is added, the price is (0.80m)(1.13). This value is Rs 904, so the marked price is ...
(0.80m)(1.3) = ₹904
m = ₹904/(0.80×1.13) = ₹904/0.904
m ≈ ₹1000
The marked price of the watch is ₹1000.
