solve the equation c²=4
Answer:
c = 2, c = -2
Step-by-step explanation:
The question is asking us to solve the equation [tex]\sf{c^2=4}[/tex].
To solve it, we take the square root of each side. Note that once we do this, we will have 2 solutions.
[tex]\sf{\sqrt{c^2}=\sqrt{4}}[/tex]
[tex]\sf{c=2,c=-2}[/tex]
Therefore, this equation has two solutions, which are c = 2 and c = -2.

What is the conclusion in this conditional statement?
If a square has a perimeter of 8 units, then its sides have a length of 2 units each.
the square has a perimeter of 8 units
the sides of the square have a length of 2 units each
Submit
The conclusion in the given conditional statement is that the sides of the square have a length of 2 units each. This is deduced from the formula for the perimeter of a square (P = 4 × side length), and the given perimeter of 8 units.
Explanation:The conclusion in the conditional statement "If a square has a perimeter of 8 units, then its sides have a length of 2 units each" is the sides of the square have a length of 2 units each.
In a conditional statement, the "if" part is known as the hypothesis and the "then" part is the conclusion. Given that a square's perimeter is the sum of the lengths of all four sides, we can show this through an equation: P = 4 × s, where P represents the perimeter and s the length of one side. Since the perimeter is given as 8 units, we can solve for s by dividing the perimeter by 4: 8 units = 4 × s, which simplifies to s = 2 units. Therefore, each side of the square must be 2 units long.
Final answer:
The conclusion in this conditional statement is that the sides of the square have a length of 2 units each.
Explanation:
The conclusion in this conditional statement is:
The sides of the square have a length of 2 units each.
In a conditional statement of the form 'if A, then B', the conclusion (B) is the statement that follows 'then'. In this case, the conclusion states that the sides of the square have a length of 2 units each.

What is PEMDAS ?
A rule of operations explains the correct order in which math expressions should be evaluated, and we can remember those steps using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Here, the expression is given as 62+(3⋅4)−24 now using PEMDAS rule to solve this expression first by solving under bracket terms 3x4 = 12 and then adding 62 and 12, then subtract it by 24 to get the final answer.

S=p-0.2t solve for p
Answer:
The required equation is [tex]S+0.2t=p[/tex]
Step-by-step explanation:
Consider the provided equation.
[tex]S=p-0.2t[/tex]
We need to solve the equation for p.
Isolate the variable as shown.
Add 0.2t from both sides.
[tex]S+0.2t=p-0.2t+0.2t[/tex]
[tex]S+0.2t=p[/tex]
Hence, the required equation is [tex]S+0.2t=p[/tex]
Wastewater is filling barrels at the rate 7 quarts per hour.The recycling facility picks up 25 full barrels each trip, and each barrel hold 48 quarts of wastewater. How many days are between each pickup
25 *48 = 1200 total quarts
1200/7 = 171.43 hours
171.42/24 = 7.14 days
so every 7 days

The floor of a conference hall can be covered completly with tiles.Its length is 36ft. longer than its width.The area of the floor is less than 2040square ft.How would you represent the with of the floor?How about its lenght?What mathematical sentence would represent the given situation?What are the possible dimensions of the floor?How about the possible areas of the floor?Would it be realistic for the floor to have an area of 144sq.ft?Explain your answer.
W<30; The width of the floor will be less than 30feet
The possible area of the floor is 1885 sq. ftSince 144 sq.ft ≠ 1885feet², hence it would not be realistic for the floor to have an area of 144sq.ft
The formula for calculating the area of the conference floor is expressed as:
A = LW
L is the length
W is the width
If the length is 36ft. longer than its width, hence;
L = W+36
Since the area of the floor is less than 2040 square feet, hence;
A < 2040
LW < 2040
(W+36)W < 2040
W² + 38W < 2040
W² + 38W - 2040 < 0
W² + 68W - 30W - 2040 < 0
W(W+68)- 30(W+68)< 0
(W-30)(W+68) < 0
W - 30 < 0 and W < -68
W < 30
Since the width cannot be negative, hence the width of the floor will be less than 30feet
Since L = 36 + W
L < 36 + 30
L < 66feet
The length of the floor will be less than 66feet
The possible dimensions area 29feet by 65feet since the width is less than 30 and the length is less than 66feet.
Get the possible area:
Possible area = 29 × 65
Possible area = 1885feet²
Since 144 sq.ft ≠ 1885feet², hence it would not be realistic for the floor to have an area of 144sq.ft

What are the coordinates of the point (2, −3) after a counterclockwise rotation of 90° about the origin?
(3, 2)
(−3, −2)
(−2, 3)
(−3, 2)
Answer:
(2,-3) changes to (3,2)
A is correct.
Step-by-step explanation:
Given: The point (2, −3) after a counterclockwise rotation of 90° about the origin.
[tex]R_{90\circ}(x,y)\rightarrow (-y,x)[/tex]
Rotation is counterclockwise about origin.
[tex](x,y)\rightarrow (-y,x)[/tex]
We are given coordinate
[tex](2,-3)\rightarrow (3,2)[/tex]
We can see in diagram also. Please see the attachment for rotation.
Hence, (2,-3) changes to (3,2)
Answer:
Point would be (3,2).
Step-by-step explanation:
Given: point (2, −3) after a counterclockwise rotation of 90° about the origin.
To find: What are the coordinates after rotation.
Solution: We have given that point (2, −3).
By transformation rotation 90° (x,y)→→→(-y,x).
Then point (2, −3) would be (-(-3),2) .
Then (3 ,2)
Therefore, Point would be (3,2).
A coin is tossed 6 times. what is the probability of getting at least one head? express your answer as a fraction or a decimal number rounded to four decimal places.
Final answer:
The probability of getting at least one head in six coin tosses is 1 minus the probability of getting tails on all tosses, resulting in a probability of 98.44% when rounded to four decimal places.
Explanation:
The question is about calculating the probability of getting at least one head when a coin is tossed six times. Rather than calculating the probability of at least one head directly, it's simpler to calculate the probability of the opposite event—getting no heads—which is the same as getting tails on all six tosses. Since the probability of flipping a tail on each toss is 0.5, the probability of flipping six tails in a row is (0.5)⁶, which equals 0.015625. Therefore, the probability of getting at least one head is 1 minus the probability of getting no heads, which is 1 - 0.015625, resulting in 0.984375 or 98.44% when rounded to four decimal places.

If the highest score in a distribution is x = 16 and the lowest is x = 4, then the range is 12 or 13 points.
a. True
b. False
The range in the given scenario is only 12 points, not 12 or 13 points as mentioned.
False
Range = Highest score - Lowest score
Range = 16 - 4 = 12
Therefore, the range can only be 12 points.

Mary invests £12000 into a savings account. The account pays 1.5% compound interest per year
Answer:
Value of her investment after 2years is £12,362.7
Step-by-step explanation:
The question is incomplete, here is the complete question.
"Mary invests £12000 in a savings account. The account pays 1.5% compound interest per year. Work out the value of her investment after two years"
Using the relationship:
A = P(1+r/100)^n
Where P is the principal = amount invested = £12000
r is the compound interest = 1.5%
n is the time = 2years
A is the amount compounded after n years
A = 12000(1+1.5/100)²
A = 12000(1+0.015)²
A = 12000(1.015)²
A = 12000(1.03)
A = 12362.7
Value of her investment after 2years is £12,362.7

Examine the work shown. Explain the error and find the correct result.
2(4 – 16) – (–30)
2(–12) – (–30)
24 – (–30)
54
The error is in third step where 2(–12) is -24 and not 24 thus the correct result is 6.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now the given expression is,
2(4 – 16) – (–30)
solving the bracket,
2(–12) – (–30)
expanding the bracket we get,
-24 – (–30)
this is the error in the given work where 2(–12)– (–30) = 24– (–30)
Thus open the bracket,
-24 + 30
solving we get,
6
which is the correct answer.
Thus, the error is in third step where 2(–12) is -24 and not 24 thus the correct result is 6.
