Stefan's city took a survey about a plan for a new park. Of the people surveyed, 2,800 liked the plan for the park and 1,200 did not. What percentage of the people surveyed liked the plan?
Answer:
70% of people surveyed liked the plan.
Step-by-step explanation:
Given that,
No. of people that liked the plan = 2,800
No. of people that did not like the plan = 1,200
We need to find what percentage of the people surveyed liked the plan. It can be given by :
[tex]\%=\dfrac{2800}{2800+1200}\times 100\\\\=70\%[/tex]
So, 70% of people surveyed liked the plan.

Evaluate the expression for the given value of the variable.
3 × (c2 − 8) for c = 3
Answer:
I am assuming c2, is c^2.
3 × (c2 − 8)
=3 ×(3^2-8)
=27-8
=19
If c2 is c*2
Then,
3 × (c2 − 8)
=3×(6-8)
=18-24
=(-6)

Answer:
1/4x function A vs 0.75x function B lastly 0.25 is less than 0.75 Give brainlistnegitive 17plus n over 5 =33 what is n
Answer:
250
Step-by-step explanation:
-17+n/5=33
n/5=33-(-17)
n/5=33+17
n/5=50
n=50*5
n=250
n=182
Step by Step Explanation:
The equation we would start out with is:
[tex] \frac{ - 17 + n}{5} = 33[/tex]
From here, we need to multiply both sides by 5. This would create an equation of -17+n=165, as we canceled out the 5.
Then, you need to add 17 to both sides to isolate the variable. This would make the equation n=182, our final answer.

Answer:
it should be 1/8
Step-by-step explanation:
The graph of y = f(x) is shown.
a) Find f(0)
4-
3.
b) Give the roots of f(x) = 0
Answer:
f(0) = 2
Roots are;
-2 and -1
Step-by-step explanation:
F(0) simply refers to the y-values when x = 0
This is the point at which the graph crosses the y-axis
the value here is 2
To
find the roots of f(x) , we simply find the points at which the plot crosses the x-axis
we have this at x = -2 and x = -1
These are what represents the roots of the equation

Terms/CoefficientsCoordinates (x, y)Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
y = -4x + 1
11y = x + 146
Step 2: Solve for x
Substitution
Substitute in y: 11(-4x + 1) = x + 146Distribute 11: -44x + 11 = x + 146[Addition Property of Equality] Add 44x on both sides: 11 = 45x + 146[Subtraction Property of Equality] Subtract 146 on both sides: -135 = 45x[Division Property of Equality] Divide 45 on both sides: -3 = xRewrite/Rearrange: x = -3Step 3: Solve for y
Define original equation: y = -4x + 1Substitute in x: y = -4(-3) + 1Multiply: y = 12 + 1Add: y = 133 6 units right and 5 units up
4. 8 units left and 1 unit down
Answer:
3: P'= (6, 5) Q'= (11, 3) R'= (3, 11)
4: P'= (-8, -1) Q'=(-3, -3) R'= (-12, 5)
Step-by-step explanation:
The question is the explanation basically. Just move the points 6 units right and 5 units up for 3, and move the points 8 units left and 1 unit down for 4.
(I hope that the two questions are called 3 and 4, and it isn't "36 units right" or "4.8 units left)
How do i find a scale factor?
Answer:
In two similar geometric figures, the scale factor is the ratio of their corresponding sides, dividing the two corresponding lengths of the sides will gives the ratio, for example
What is the scale factor between 4 cm and 10 cm ?
4 and 10 are divisible by 2
Length A : 4 ÷ 2 = 2
Length B : 10 ÷ 2 = 5
so the scale factor from A to B is 2:5

6√3
Step-by-step explanation:
6 is x. side across from right angle (12) is 2x. so 6x2 to get 12. missing side is x√3. so 6√3
Answer:
6√3
Step-by-step explanation:
using the pythagorean theorem you can plug in the numbers to get √(12^2 - 6^2) = √(144-36) = √108 = 6√3.
