Find the area and the circumference of a circle with diameter of 5m. Use the value 3.14 for π, and do not round your answers. Be sure to include the correct units in your answers
Answer:
Step-by-step explanation:
Diameter (d) = 5cm
Radius ( r) = d/2 = 5 / 2 = 2.5
Now
Area
= πr²
= 3.14 * (2.5)²
= 19.625 m²
Circumference
= πd
= 3.14 * 5
= 15.7 m
Hope it will help :)

Find the common ratio of the geometric sequence 36, 6, 1, 16, ... . Write your answer as an integer or fraction in simplest form.
Answer:
Step-by-step explanation:
The common ratio is the constant found by dividing any term by the previous term.
r=6/36=1/6
r=1/6
I am assuming the 16 at the end of the sequence was a typo. IF 16 was at the end of the sequence it is NOT a geometric sequence as there would not be a common ratio for all terms.

find the values of x and y.
Answer:
x = 20, y = 70
Step-by-step explanation:
The angle adjacent to 40° is 180° - 40° = 140°
Since the triangle on the right has 2 congruent sides then it is isosceles and its base angles are congruent, both x
2x + 140 = 180 ← sum of 3 angles in triangle
Subtract 140 from both sides
2x = 40 ( divide both sides by 2 )
x = 20
------------------------------------------
The angle inside the triangle on the left is 90° - 20° = 70° , then
y = 180 - (40 + 70) = 180 - 110 = 70

Amber trains for 1h one day. She runs for 10 min, walks for 5 min, runs for 15 min, and walks for 5 min. Her running time increases by 5 min each interval, but she always walks for 5 min. Use fractions of one hour. Write an addition equation that represents Amber's total running time. Find her total running time.
Answer:
Part A
The addition equation that gives Amber's total running time is presented as follows;
Amber's total running time = 1/6 hr + (1/6 + 1/12) hr + 5/12 hr
Part B
Amber's total running time = 5/6 hr = 50 minutes
Step-by-step explanation:
Part A
The given parameters are;
The time duration Amber first ran = 10 min = 1/6 hr
The time duration Amber walks in between = 5 min = 1/12 hr
The increase in the number of minutes Amber runs in subsequent times = 5 min = 1/12 hr
Therefore, the Amber's total time is given as follows;
1/6 hr + 1/12 hr + (1/6 + 1/12) hr + 1/12 hr + x hr = 1 hr
7/12 hr + x hr = 1 hr
x hr = 1 hr - 7/12 hr = 5/12 hr
x = 5/12
Therefore, her total running time is given by the following addition equation;
Amber's total running time = 1/6 hr + (1/6 + 1/12) hr + 5/12 hr
Part B
Therefore her total running time is given as follows;
Amber's total running time = 1/6 hr + (1/6 + 1/12) hr + 5/12 hr = 5/6 hr = 50 minutes

An article bought for Rs1000 is sold in fourth-fift of the cost prize . What is the profit percentage?
Answer:
-20%
Step-by-step explanation:
Given that :
Purchase price = Rs1000
Price sold = 4/5 of the purchase price
Price sold = 4/5 * 1000 = Rs. 800
Profit Percentage :
(price sold - purchase price) / purchase price * 100%
(800 - 1000) / 1000 * 100%
(-200 / 1000) * 100%
-0.2 * 100%
-20%
What are the zeros of f(x) = x2 + x – 30?
A. x = –6 and x = 5
B. x = –5 and x = 6
C. x = –15 and x = 2
D. x = –2 and x = 15
Answer:
Answer A is correct. (x + 6)(x - 5) = x^2 + x - 30.
Step-by-step explanation:
Note that -30 = (-5)(6) and (5)(-6). This quadratic can be factored easily:
x^2 + x - 30 = (x + 6)(x - 5) is correct because 6x - 5x = x, the middle term of x^2 + x - 30.
Setting each factor equal to zero, one by one, we get:
x + 6 = 0 => x = -6, and x - 5 = 0 => x = 5
Answer A is correct.

Find the degree measure of each angle in the triangle. Giving brainly
Answer:
∠ I = 39°, ∠ J = 51°, ∠ K = 90°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the3 angles and equate to 180
3x + 21 + 5x + 21 + 90 = 180, that is
8x + 132 = 180 ( subtract 132 from both sides )
8x = 48 ( divide both sides by 8 )
x = 6
Then
∠ I = 3x + 21 = 3(6) + 21 = 18 + 21 = 39°
∠ J = 5x + 21 = 5(6) + 21 = 30 + 21 = 51°
∠ K = 90°

A triangle has a 62° angle and a right angle. What is the measure of the third angle?
Answer:
Measure of the third angle is 28°
Step-by-step explanation:
A Triangle has three angles in total which when summed up equal to 180 degrees. Now the information in the question is that the first angle is 62° the second angle is a right angle which means it is a 90° angle and we need the third angle, and when all of this when added equals 180° So,
We let the third angle be called x.
[tex]62 + 90 + x = 180\\\\152+x=180\\\\x=180-152\\\\x=28[/tex]
So our third angle is 28°
Step-by-step explanation:
Sum of angles on a straight line = 180°
Let the third angle be x°
62° + 90° + x° = 180°......(Sum of angles on a straight)
152° + x. = 180°
x°. = 180°-152°
x° =28°

which is a property of a parallelogram?
Answer:
Opposite sides are congruent (AB = DC).
Opposite angels are congruent (D = B).
The sum of all the angles equals 180 degrees.
If one angle is right, then all angles are right.
The diagonals of a parallelogram bisect each other.
Each diagonal of a parallelogram separates it into two congruent triangles.

Answer:
the coefficient is 2
2x^4 = 2 * x^4 = 2 is the coefficient
hope that helps
Answer:
2
Step-by-step explanation:
The coefficient of a term is the number that multiplies the variables of the term.
In the term 2x^4, the number multiplying the variables is 2, so the coefficient is 2.
