Leslie created a scale drawing of her house for art class. In the scale drawing the length of her bedroom is 8 cm. The length of her actual bedroom is 24 m. Which scale did Leslie use to create the scale drawing of her home?
Answer:
She used an 300:1 ratio to create the drawing.
Step-by-step explanation:
24 meters is 2400 centimeters
2400/8=300
Therefore the ratio is 300:1
Solve the equation. −2 1/4=r−4/5 will give brainiest for the first correct answer!!!
Answer:
r = -1 9/20
Step-by-step explanation:
-2 1/4 = r - 4/5
Switch sides:
r - 4/5 = -2 1/4
Add 4/5 to both sides.
r = -2 1/4 + 4/5
Change the mixed numeral into a fraction:
r = -9/4 + 4/5
The LCD is 20.
r = -45/20 + 16/20
r = -29/20
r = -1 9/20

4. Gilbert works picking strawberries. He
earns $2.50 for each large basket he fills.
a) Draw a scatter plot to represent the
relationship between the number of
baskets Gilbert fills and the money
he earns.
b) If Gilbert's goal is to earn $360.
how many baskets must he fill?
c) Write an algebraic expression to
describe the relationship.
Answer:
Graph is attached
144 baskets
[tex]y=2.5x[/tex]
Step-by-step explanation:
Let y be the total amount of money Gilbert earns and x be the number of baskets filled. So, we get the relation
[tex]y=2.5x[/tex]
Some points which satisfy the equation is
[tex]y=2.5\times 1\\\Rightarrow y=2.5[/tex]
[tex](1,2.5)[/tex]
[tex]y=2.5\times 3\\\Rightarrow y=7.5[/tex]
[tex](3,7.5)[/tex]
[tex]y=2.5\times 5\\\Rightarrow y=12.5[/tex]
[tex](5,12.5)[/tex]
His goal is to earn $360 so [tex]y=360[/tex]
[tex]360=2.5x\\\Rightarrow x=\dfrac{360}{2.5}\\\Rightarrow x=144[/tex]
Hence, to earn $360 he must fill 144 baskets.
The algebraic relation is [tex]y=2.5x[/tex].
Suppose that in an election for governor of Oregon there are five candidates of whom two are women. A statistics student reasons as follows: the probability that a woman will win the election is equal to 2/5. What is wrong with this reasoning?
Answer:
If in an Oregon state gubernatorial election, 2 of the 5 candidates are women, and a statistics student establishes that there is a 2/5 chance that the person elected for governor is a woman, this reasoning will be wrong.
This will be the case because not all candidates have the same amount of votes, that is, not all start with the same conditions: thus, there are more popular candidates than others, who will have greater probabilities of being elected as governors, regardless of their sexual identity.

Answer:
x = 24
Step-by-step explanation:
x/4 + 10 = 16
subtract 10 from both sides of the equation
x/4 + 10 - 10 = 16 - 10
x/4 = 16 - 10
x/4 = 6
multiply both sides of the equation by 4
x/4 * 4 = 6 * 4
x = 6 * 4
x = 24

Choose the system of equations which matches the following graph: (5 points)
Answer:
-5x + y = -7
2x + y = 0
Step-by-step explanation:
Equation of the line that slants upwards from left to your right:
The slope (m) = rise/run = (5/1) = 5
Using a point on the line, (2, 3) and the slope, substitute x = 2, y = 3, and m = 5 into y = mx + b to find the value of b.
Thus:
3 = 5(2) + b
3 = 10 + b
3 - 10 = b
-7 = b
Substitute m = 5 and b = -7 into y = mx + b
First equation of the system would be:
y = 5x - 7
Rewrite, you'd have:
-5x + y = -7
Equation of the line that slants downwards from left to your right:
Slope (m) = rise/run = -(2/1) = -2
y-intercept, b = 0 (the point where the line intercepts the y-axis)
Substitute m = -2 and b = 0 into y = mx + b.
y = -2x + 0
Rewrite, you'd have:
2x + y = 0
✔️The equations of the system are:
-5x + y = -7
2x + y = 0

which calculation correctly uses prism factorization to write the square root of 420 in simplest form?
[tex] \sqrt{420} [/tex]
240 = V2 - 2 - 2 3.5 = 2/30
240 = 2 . 2 . 2 . 2 = 4/3
240 = 2 . 2 . 2 . 2 3.5 4/15
240 V2 · 2 · 2 · 3 3. 10 = 2/60
Answer:
[tex]\sqrt{420}=\sqrt{2\times2\times3\times5\times7} =2\sqrt{105}[/tex]
Step-by-step explanation:
We need to write prime factorisation to solve [tex]\sqrt{420}[/tex]
Prime factorisation: We need to find only those prime factors that are divisible
So, Prime factors of 420 are: 2x2x3x5x7
Now replacing 420 with its prime factors
[tex]\sqrt{420}\\=\sqrt{2\times2\times3\times5\times7} \\=\sqrt{2^2\times3\times5\times7} \\=\sqrt{2^2}\sqrt{3\times5\times7}\\=2 \sqrt{105}[/tex]
Since the options are incomplete, kindly verify the options.
So, [tex]\sqrt{420}=\sqrt{2\times2\times3\times5\times7} =2\sqrt{105}[/tex]

prove that:- (1-sinA)(1+sinA)÷(1+cosA)(1-cosA)=cot^2A
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 , then
sin²x = 1 - cos²x and cos²x = 1 - sin²x
Consider the left side
[tex]\frac{(1-sinA)(1 + sinA)}{(1+cosA)(1-cosA)}[/tex] ← expand numerator/denominator using FOIL
= [tex]\frac{1-sin^2A}{1-cos^2A}[/tex]
= [tex]\frac{1-(1-cos^2A)}{1-(1-sin^2A)}[/tex]
= [tex]\frac{1-1+cos^2A}{1-1+sin^2A}[/tex]
= [tex]\frac{cos^2A}{sin^2A}[/tex]
= cot²A = right side , thus proven

On a road with 24 streetlights, 3 of them do not work. What is the ratio of streetlights on the road that work to streetlights that do not work?
Answer:
8:1
Step-by-step explanation:
Ratio of working streetlights to streetlights that do not work is 7:1
Given that;Total number of streetlight = 24
Not working streetlight = 3
Find:Ratio of working streetlights to streetlights that do not work
Computation:Working streetlights = 24 - 3
Working streetlights = 21
Ratio of working streetlights to streetlights that do not work = Working streetlights / Streetlights that do not work
Ratio of working streetlights to streetlights that do not work = 21 / 3
