Mr samuel built a circular fenced-in section for some of his animals the section has a circumference of 55. What is the approximate area in square meters of the section? Use 22/7 for pie
Answers
Answer:
240.6 m²
Step-by-step explanation:
Mr samuel built a circular fenced-in section for some of his animals the section has a circumference of 55. What is the approximate area in square meters of the section? Use 22/7 for pie
Step 1
We have to find the radius of the circular fence
The circumference of a circle = 2πr
Circumference = 55m
Hence:
55m = 2 × 22/7 × r
55 = 44/7
r = 55 ÷ 44/7
r = 55 × 7/55
r = 8.75m
Step 2
We find the approximate area in square meters of the section.
Area of a circle = πr²
Area of the circle = 22/7 × 8.75²
Area of the circle = 240.625 m²
Approximately = 240.6 m²
Therefore, the approximate area in square meters of the section is 240.6m²

Answers
Answer:
a = 5
Step-by-step explanation:
(x+3)(x+a)(x+7)=x³+15x²+71x+105
(x+3)(x+a)(x+7) = (x²+10x+21)(x+a) = x³ + (10+a)x² + (21+10a)x + 21a
21a = 105
a = 5

Manufacturers of a new pain medication designed a double-blind experiment to test their new formula to see if
sufferers of migraines feel relief after taking it. A total of 80 patients with migraines were recruited for the study.
The researchers asked each patient to rate their pain on a scale of 1 (mild) to 10 (severe). Then the researchers
randomly assigned each migraine sufferer either the new pain medication or a placebo. One hour later, each
patient was again asked to rate the level of pain from 1 to 10. Why was it important for this experiment to be
double-blind?
If the subjects knew they were not receiving the active treatment, they might quit the experiment.
It was important for both the subjects and the researchers to know which treatment was being assigned to the
subjects so they could see if the improvement of migraine pain was due to the new medication or to the
expectation of getting better.
O It was important for the subjects to know if they were receiving an active treatment so they could keep track of
any possible side effects. If the researchers knew which subjects received which treatments, they might have
treated one group of subjects differently from the other group.
If subjects knew they were receiving an active treatment, researchers would not have known if any
improvement was due to the new medication or to the expectation of feeling better. If the researchers knew
which subjects received which treatments, they might have treated one group of subjects differently from the
other group.

Andrew drove 6 hours to get to his uncle's house. He drove at an average speed of 48 miles per hour.
Answers
Answer:
I guess that we want to find the displacement between Andrew's house and his uncle's house.
Assuming that he drove in a straight line, we can use the relationship:
Distance = Speed*Time.
We know that he drove for 6 hours, and the speed was 48 miles per hour, then the distance will be:
distance = 6h*48mi/h = 288 mi
This means that the total distance is 288 miles.

And hegarty said that 1204.23 was incorrect...
Answers
Answer:
1233.02 to 2 D.P.
Step-by-step explanation:
4 % = 0.04
So to obtain the amount after increase by 4% we multiply by 1.04:
1235 * 1.04 = 1284.4
Decreasing by 4%: we mutriply by 1 - 0.04 = 0.96:
1284.4 * 0.96
= 1233.024.
Answer: 1233.02
Step-by-step explanation:
4% = 0.04
1235 × 0.04 = 49.4 (the original number was increased by this amount)
1235 + 49.4 = 1284.4 (new number after increment)
1 284.4 × 0,04 = 51.376 (the number has been reduced by this amount)
1284.4 - 51.376 = 1233.024- final amount.
Rounded to 2 DP: 1233.02

Answer:

Step-by-step explanation:
i just did it and was right
The required values of the r that shows the positive slope are 1, 0.5, and 0.8.
Given that,
To select the values for r that indicate a positive slope for the line
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
y -y₁ =(y₂ - y₁) / (x₂ - x₁) (x - x₁)
Here,
The positive slope is defined as the positive value of the r, not also zero because zero represents the contant nature of the function while the positive slope shows the increasing nature of the function or curve.
Thus, the required values of the r that shows the positive slope are 1, 0.5, and 0.8.

Given that NPQR, MN is congruent to MR and NP is congruent to QR, fill in the reasons below to prove that MPQ is isosceles
Answers
Answer:
All the reasons to prove that triangle MPQ is isosceles are mentioned below in the explanation section.
Step-by-step explanation:
1. NPQR, MN is congruent to MR
Reason: Congruency is defined as , any shape or geometry is become other by application of flips, translations, rotations, movement, angle change or the combination of any then these two shapes are congruent. Here, MR line and MN are one shape just angles are changed.
2. Angle of N ≅ Angle of R
Reason: It is true because the Triangle MNR is a isosceles triangle, having two equal angles and two same sides.
3. Triangle MNP is congruent to Triangle MRQ
Reasons: Because, firstly MN is congruent to MR, Angle of N and Angle of R is same, thirdly, NP is congruent to QR.
4. MP ≅ MQ
Reason: Similar side of congruent triangle MNP and MRQ.
5. Triangle MPQ is isosceles:
Reason: Because MP and MQ are congruent, hence triangle MPQ is isosceles with two equal angles and two equal sides because of congruency of MP and MQ.
