Can someone answer this question please please help me I really need it if it’s correct I will mark you brainliest .
Step 1) Use the area formula to find the length of the radius
A = (3.14 x r^2) / 4
3.14 = (3.14 x r^2) / 4
12.56 = 3.14r^2
r^2 = 4
r = 2 feet
Step 2) Use the perimeter formula to find the perimeter
C = ((pi x 2r) / 4) + 2r
C = ((3.14 x 4) / 4) + 4
C = (12.56 / 4) + 4
C = 3.14 + 4
C = 7.14 feet
Hope this helps! :)
Please help!You roll a 6-sided die two times.
What is the probability of rolling a number less than 4 and then rolling an odd number?
Write your answer as a percentage.
Answer:
rolling a number less than 4=
1,2,3 are less than 4 and a die is 6 sided so that will be 3/6 which in lowest terms is 1/2
1/2 as a percentage is 1/2*100=50%
rolling an odd number=
on a 6 sided die there are 3 odd numbers which are 1,3 and 5=
3/6 which in lowest terms is also 1/2
so 1/2*100=50%

Quadrilateral EFGH is inscribed in a circle. If m∠F = 114° and m∠G = 78° then which of the following is the measure of ∠H?
Answer:
I think its 66
Step-by-step explanation:
Since if you draw it out properly F would be opposite of H.
Oppsite angles in a quadrilateral are supplementary(in a circle at least) meaning they add up to 180.
So 180-114= 66
So H=66

Whats the product of (-3x+2y)(4x-y)
Answer:
-12x^2 + 11xy - 2y^2
Step-by-step explanation:
Answer:
-12x² + 11xy - 2y²
Step-by-step explanation:
To solve this:
You can distribute -3x to 4x
-3x*4x = -12x²
Then distribute the -3x to -y
-3x*-y = 3xy
Distribute the 2y to 4x
2y*4x = 8xy
Distribute the 2y to -y
2y*-y = -2y²
-12x² + 3xy + 8xy - 2y²
Combine like terms and add 3xy to 8xy
Final Answer: -12x² + 3xy + 11xy - 2y²

Need Help! Unit Activity: Inferences and Decision-Making from Data
Answer:
Part B
This statement means that we are 95% confident that our confidence interval and our point estimate of our results from this sample contains the true proportion of national adults who fulfill a certain condition. The margin of error is plus or minus 4 percentage points in our survey, so we are fairly accurate / close to our point estimate.
Part C
Personally, I think that the minimum quota should be different, because nowadays very few people have landlines, and most people have cell phones. I would put it at 80% cell phones, 20% landlines, for the most representative survey possible.
Part D
Unfortunately, there isn't enough information to explain this one, because I can't see the link or view the responses and trends. I would give you the advice that you might want to include all variables and survey conditions: what type of survey was it? how many adults were sampled? what are your hypotheses or preconceived notions? what is the standard error? This should help; if not, please clarify.

Answer:
AE Measure: 23.36 units
Step-by-step explanation:
BA: 20cm
BC:20cm
BE:10cm CE: 10cm
a^2 +b^2=c^2
BE^2 +BA^2 = AE^2
√100 + √400 = √500
AE^2 = √500 = 23.36
AE = 23.36 unit
Repeat effort :-)
Step-by-step explanation:
As ABCD is a square , BC = 20 cm
BE = 20/2 = 10 cm
Also , angle B = 90⁰
By pythagoras theorem :
AE² = 20² + 10²
AE² = 400 + 100
AE² = 500
AE = 10√5 cm

Determine the minimum amount of packaging needed to completely cover a
triangular prism Oblerone bar with these dimensions: length 22.5 cm; triangular face
A right triangular prism has 3 rectangular faces.
If each of the edges of the triangular base measures 4.5cm,
and the length (the height) of the prism is 22.5cm,
the 3 rectangular faces (sides of the box) are rectangles,
22.5cm long and 4.5cm wide.
Each face has a surface area of (22.5cm)(4.5cm)=101.25 square centimeters.
The total lateral surface area for the 3 rectangular sides of the box is
3(101.2 square centimeters)=303.75 square centimeters.
If the triangular faces of the box are triangles
with a base measuring 4.5cm and a height measuring 4.0cm,
the surface area of each triangular face is
(1/2)(4.5cm)(4.0cm)=9 square centimeters.
The surface area of the two triangular faces adds up to
2(9 square centimeters)=18 square centimeters.
The total surface area for the box is
303.75 square centimeters + 18 18 square centimeters= 321.75 18 square centimeters,
and that rounds up to highlight 322 square centimeters.
NOTE:
The answer above is the one your teacher wants,
but there is a problem with this problem.
An equilateral triangle with sides measuring 4.5cm
would have a height of approximately 3.9cm.
The Pythagorean theorem says so.
However, the 4.0cm value makes the calculations easier.
Answer:
A right triangular prism has 3 rectangular faces.
If each of the edges of the triangular base measures 4.5cm,
and the length (the height) of the prism is 22.5cm,
the 3 rectangular faces (sides of the box) are rectangles,
22.5cm long and 4.5cm wide.
Each face has a surface area of (22.5cm)(4.5cm)=101.25 square centimeters.
The total lateral surface area for the 3 rectangular sides of the box is
3(101.2 square centimeters)=303.75 square centimeters.
If the triangular faces of the box are triangles
with a base measuring 4.5cm and a height measuring 4.0cm,
the surface area of each triangular face is
(1/2)(4.5cm)(4.0cm)=9 square centimeters.
The surface area of the two triangular faces adds up to
2(9 square centimeters)=18 square centimeters.
The total surface area for the box is
303.75 square centimeters + 18 18 square centimeters= 321.75 18 square centimeters,
and that rounds up to highlight 322 square centimeters.

At a school fair, students were challenged to hit one of the small congruent circles on the large rectangular board with a ball. Find the probability of hitting any small circle. Type answer as a percent. *
Answer:
The probability of a student to hit any small circle is 4.66 %.
Step-by-step explanation:
In order to determine the probability of the students to hit the small circles, we need to calculate the are of the rectangle and the area of each circle. These are shown below:
area circle = pi*r² = pi*(3)² = 28.26 in²
area rectangle = 35*52 = 1820 in²
Since there are three circles and the students can hit any of those the probablity of hitting them is given by the area of one circle multiplied by 3 and divided by the area of the rectangle.
p = [(3*area circle)/(area rectangle)]*100%
p = [(3*28.26)/1820]*100 = 4.66 %
