A scale drawing of a lake has a scale of 1 cm to 80 m. If the actual width of the lake is 1000 m, what is the width of the lake on the scale drawing? Explain or show your reasoning.
Answer:
The scale would be 12.5 centimeters
Step-by-step explanation:
It’s pretty easy
since it’s 1 cm to 80m there’s two ways to solve this but the fastest way is to find the unit rate of the scale
So 1000m/80m to find the cm
so the answer would be 12.5cm.
Check: 12.5 (80)=1000m is correct
The easier way but longer way is to create a proportion
so let’s do cm/m
so 1cm/80m
then write a proportion
1cm/80m=X cm/1000m
Cross multiply and you’ll get 1000=80x
solve the equation and you’ll get 12.5cm also
(remeber don’t change the way if the centimeter is the numerator the the second fraction, the centimeter is also the numerator same with the meters where if it’s the denominator then the other fraction is also a denominator)
Four squares ABCD, EFGH, IJKL, and MNOP are constructed such that points E, F, G, H are middle points (midpoints) of the sides of square ABCD. Points I, J, K, L are midpoints of the square EFGH. M, N, O, and P are midpoints of the square IJKL. What is the area of the square ABCD, if OP=2 cm?
By definition, the area of the parallelogram is given by:
A = b * h
Where,
b: base
h: height
We have then:
ABCD parallelogram:
A = (3) * (3)
A = 9 units ^ 2
EFGH parallelogram:
A = (3) * (3)
A = 9 units ^ 2
Answer:
The area of parallelogram ABCD is equal to the area of parallelogram EFGH.

Which expression is equivalent to "-4 - (-5)"?
5 - (-4)
5 + 4
-4 + 5
4 + 5
solve - 5x -3 + 4x + 1= -4
Answer:
x = 2
Step-by-step explanation:
Solve for x:
4 x - 5 x - 3 + 1 = -4
Hint: | Group like terms in 4 x - 5 x - 3 + 1.
Grouping like terms, 4 x - 5 x - 3 + 1 = (4 x - 5 x) + (1 - 3):
(4 x - 5 x) + (1 - 3) = -4
Hint: | Combine like terms in 4 x - 5 x.
4 x - 5 x = -x:
-x + (1 - 3) = -4
Hint: | Evaluate 1 - 3.
1 - 3 = -2:
-2 - x = -4
Hint: | Isolate terms with x to the left hand side.
Add 2 to both sides:
(2 - 2) - x = 2 - 4
Hint: | Look for the difference of two identical terms.
2 - 2 = 0:
-x = 2 - 4
Hint: | Evaluate 2 - 4.
2 - 4 = -2:
-x = -2
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of -x = -2 by -1:
(-x)/(-1) = 2
Hint: | Any nonzero number divided by itself is one.
(-1)/(-1) = 1:
Answer: x = 2

if theresa's height is 60 inches tall and steve is 6 inches shorter than one and one third times theresa's height how tall is steve?
Steve is 74 inches tall
Answer:
74 inches tall
Step-by-step explanation:
First, let's find out what [tex]1\frac{1}{3}[/tex] multiplied by 60 is.
60·[tex]1\frac{1}{3}[/tex] =80
Then, let's subtract 6 from 80.
80-6=74
So, Steve is 74 inches tall.
If the graph of y = (x - 2)^2 - 3 is translated 5 units up and 2 units to the right, then the equation of the graph obtained is given by
A. y = x^2 + 2
B. y = (x - 2)^2 + 5
C. y = (x + 2)^2 + 2
D. y = (x - 4)^2 + 2
Let f(x) = x^2 + 2x + 4. Which of the following statements is NOT true?
A. f(x) has a maximum value
B. The graph of f is not a line
C. The graph of f has no x-intercepts.
D. The graph of f has a y-intercept.
Answer:
d and a
Step-by-step explanation:
Hi friend
The the equation of the graph obtained is y = [tex](x - 4)^2 +2[/tex] and the NOT true statement is f(x) has a maximum value .
What is translation in graph?A translation is a movement of the graph either horizontally parallel to the axis or vertically parallel to the axis. To move a graph right, we add a negative value to the x-value. To move a graph left, we add a positive value to the x-value.
According to the question
1> The graph of y = [tex](x - 2)^2 - 3[/tex]
translation 5 units up and 2 units to the right
Now,
translation 5 units up that means we have to add +5 to move it up
i.e
y = [tex](x - 2)^2 - 3[/tex] + 5
y = [tex](x - 2)^2 +2[/tex]
Then
translation 2 units to the right
as per translation rules:
To move a graph right, we add a negative value to the x-value. To move a graph left, we add a positive value to the x-value.
i.e
y = [tex](x - 2-2)^2 +2[/tex]
y = [tex](x - 4)^2 +2[/tex]
2>The equation f(x) = [tex]x^2 + 2x + 4[/tex]
Analyzing all the options
Option A : f(x) has a maximum value
This statement is not true as y or f(x) can not be always max or min for all values of (x) .
Option B: The graph of f is not a line
This is true as it is a quadratic equations its graph will be parabola .
Option C: The graph of f has no x-intercepts
This statement is true as x intercepts means y = 0
but it cannot be possible
Option D: The graph of f has a y-intercept.
This statement is true as y intercepts means x = 0
at x= 0
the equation will be
f(x) = [tex]x^2 + 2x + 4[/tex]
f(x) = [tex]4[/tex]
Hence, The the equation of the graph obtained is y = [tex](x - 4)^2 +2[/tex] and the NOT true statement is f(x) has a maximum value .

Factorise mx+cx+my+cy
With steps!!!
x=algebra x
Step-by-step explanation:
Hey there!
While factorising you remember to make it take common in most of the expression.
Here;
=mx+cx+my+cy
Take common 'x' in "mx+cx" and 'y' in my + cy.
= x(m+c) + y(m+c)
Now, "(m+c)" common again.
= (m+c) (x+y)
Therefore the factorized form of the expression in (m+c)(x+y).

Answer:
Each person should have 12 pencils
Step-by-step explanation:
So first you add the number of pencils each person has:
14 + 9 + 12 + 13 + 12 = 60
Then divide this amount by the number of people :
60 / 5 = 12
The answer then becomes 12 pencils per person.

What is the mean change in the forecasted high temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the high temperatures. Show your work and steps. If your answer is not an integer, explain what two integers your answer is between.
Answer:
you need to add the seven temperatures up then divide by how many terms there are then you have the mean/average
Step-by-step explanation:
I'm an FLVS student and had this assignment last year. I attached screenshots of my paper so you can see how to answer the questions. Please just dont copy my work word-for-word; you'll get flagged for plagerism by TurnItIn. Just apply the same methods to your own data.
So for the questions in part B, here's what you could say:1. What is the mean change in the forecasted high temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the high temperatures. Show your work and steps. If your answer is not an integer, explain what two integers your answer is between.
Add all the diffrences in high temperature: 0 + 1 + (-2) + 0 + (-5) + 0 = (-6). Then divide the answer, negative six, by the number of days, six: (-6) ÷ 6 = (-1). This shows that the mean change in forecasted high temperature is (-1).
2. What is the mean change in the forecasted low temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the low temperatures. If your answer is not an integer, explain what two integers your answer is between.
Add all the diffrences in low temperature: (-1) + 1 + 0 + 0 + (-7) + (-2) = (-9). Then divide the answer, negative nine, by the number of days, six: (-9) ÷ 6 = (-1.5). Because this answer is not an interger, we will represent the mean by the two interegers it is between. The mean change in forecasted low temperature is between (-2) and (-1).
