circumference of circle: 2πr ("r" is the radius)
==========
2πr 2π(2.5)5π15.7 cmAnswer:
15.7 cm²
Step-by-step explanation:
Given:
[tex]\text{Radius of circle: 2.5 cm}[/tex]
Formula:
[tex]\text{Circumference:} \ 2\pi r[/tex]
Substitute the radius in the circumference formula:
[tex]\implies \text{Circumference:} \ 2\pi r[/tex]
[tex]\implies \text{Circumference:} \ 2\pi (2.5)[/tex]
Take π as 3.14 (Approx. value of π):
[tex]\implies \text{Circumference:} \ 2(3.14)(2.5)[/tex]
Simplify the circumference:
[tex]\implies \text{Circumference:} \ (3.14)(5)[/tex]
[tex]\implies \text{Circumference:} \ 15.7 \ \text{cm}^{2}[/tex]
To find the missed spaces
Step-by-step explanation:
all coefficients are integers, the rational zeros theorem can be applied.
that means each rational solution ("root") x = p/q, written in most simplified terms so that p and q are relatively prime, can be found for the polynomial
an×x^n + an-1×x^(n-1) + ... + a1×x + a0
p is an ± integer factor of the constant term a0, and
q is an ± integer factor of the leading coefficient an.
in our case here
an = a4 = 1
a0 = 8
the only factor for 1 is ±1.
the factors for 8 are
±1, ±2, ±4, ±8
so, we get
1/1, 2/1, 4/1, 8/1, -1/1, -2/1, -4/1, -8/1, 1/-1, 2/-1, 4/-1, 8/-1, -1/-1, -2/-1, -4/-1, -8/-1
that leaves us with the different values of
1/1, 2/1, 4/1, 8/1, -1/1, -2/1, -4/1, -8/1
sorted from smallest to largest
-8/1, -4/1, -2/1, -1/1, 1/1, 2/1, 4/1, 8/1
or simply
-8, -4, -2, -1, 1, 2, 4, 8

Answer:
30 inches
Step-by-step explanation:
In equilateral triangle all sides are equal. One side of the triangle EB is also the side of a square.
So, all the sides of the square is 6 inches
Perimeter = sum of all sides
= AB + BC + CD + DE + EA
= 6 + 6 + 6 + 6 + 6
= 5*6
= 30 inches
Answer:
Here,
length of the square BCDE(l)= 6 inches
Also,
length of the equilateral triangle ABE(l)=6 inches
Lastly, Perimeter of figure ABCDE= 5*6
=30 inches
or,Perimeter of the figure ABCDE also=
AB+BC+CD+DE+EA
=6+6+6+6+6
=30inches
Step-by-step explanation:
We know,
length DC of the square BCDE(l)=6inches
So,
DC=BC=BE=DE (All sides of a square are equal)
Again,
length BE of the equilateral triangle ABE=6inches
So,
BE=AB=AE (All sides of a equilateral triangle are equal)
Therefore, Perimeter of figure ABCDE=
AB+BC+CD+DE+EA or, 5*6
(perimeter means to sum all the outer sides a given polygon, in this case it's a Pentagon)

Two dice are tossed 396 times. How many times would you expect to get a sum of 3?
Using proportions, it is found that you would expect to get a sum of 3 22 times.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
When two dice are rolled, there are 36 total outcomes. 2 of them, (1,2) and (2,1), result in a sum of 3, hence the proportion is given by:
p = 2/36 = 1/18.
Out of 396 tosses, the expected value is given by:
E = 1/18 x 396 = 22.

What is the area of the triangle figure?
The area of the triangle is equal to 12 mm².
Area of triangle
The area of a triangle is given by the formula:[tex]A=\frac{bh}{2}[/tex], where:
b= length of the base;
h=height
STEP 1 - Find the dimensions for the base and the height of the triangle.From the figure, it is possible to see that h= base of rectangle - 4 mm. Then, the height of the triangle(h)= 10-4=6 mm.
You can see that the sum of the base of the triangle with the height of the rectangle is equal to 12 mm. The figure also shows that the height of this rectangle is equal to 8 mm. Thus, the base of the triangle(h)= 12-8=4 mm.
STEP 2 - Find the area of the triangle.
From step 1:
b= length of the base= 4
h=height=6
Therefore, the area of the triangle - [tex]A=\frac{bh}{2}=\frac{4 * 6}{2}=\frac{24}{2} =12 mm^2[/tex].

a. If mQR = 80° and mQS = 150°, what is mZP?
Answer:
mP = 35
Step-by-step explanation:
QR = 80
QS = 150
The measure of the angle formed by a secant and a tangent intersecting in the exterior of a circle is half the difference between the measures of the intercepted arcs.
This means that (150-80)/2 = mP
mP = 35 degrees

Given circle O with diameter AB find x
A circle is a curve sketched out by a point moving in a plane. The measure of x is 60°.
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
Given that the measure of the arc AC is 120°. Now, as we know, the diameter divides the circle into two equal chords of 180° each. Therefore, the measure of x can be written as,
[tex]x = {\rm arcAB-arc AC}\\\\x = 180^o-120^o\\\\x = 60^o[/tex]

Find the Unit Price for each bottle of conditioner. Which bottle of hair conditioner is the best buy?
8 oz for $1.49
12 oz for $2.29
15 oz for $2.75
20 oz for $3.89
Answer:
D.
Step-by-step explanation:
We know that to find unit price, we divide the unit in the numerator by the quantity in the denominator.
For the first option, we must put $1.49 as the numerator and 8 as the denominator. It will then look like this:
[tex]\frac{1.49 / 8 }{8 / 8\\}[/tex] Then we must divide 1.49 by 8. This will get us $0.18625.For our second option, we must put $2.29 as the numerator, and 12 as the denominator. It will look like this:
[tex]\frac{2.29 / 12 }{12 / 12\\}[/tex] Then we must divide 2.29 by 12. This will get us $0.19083 (rounded)For our third option, we must put $2.75 as the numerator, and 15 as the denominator. It will look like this:
[tex]\frac{2.75 / 15 }{15 / 15}[/tex]Then we must divide 2.75 by 15. This will get us $[tex]0.18333[/tex] (rounded)For our final option, we must put $3.89 as the numerator, and 20 as the denominator. It will look like this:
[tex]\frac{3.89 / 20 }{3.89 / 20}[/tex]Then we must divide 3.89 by 20. This will get us $0.1945 (rounded)Therefore, the last option is the best buy because $0.18625 > $0.18333.

Answer:
30°
Explanation:
∠LMP + ∠PMN = 180°
[∠LMO + ∠OMP] + [∠PMR + ∠RMN] = 180°
FIND x
(x - 10) + (x + 30) + x + 40 = 180
3x - 10 + 30 + 40 = 180
3x + 60 = 180
3x = 120
x =40
FIND ∠LMO
∠LMO = x - 10
∠LMO = (40) - 10
∠LMO = 30°
Hope this helps and God bless!
Answer:
∠LMO = 30°
Step-by-step explanation:
Angles on a straight line add up to 180°
⇒ (x - 10)° + (x + 30)° + 40° + x° = 180°
⇒ x° + x° + x° - 10° + 30° + 40° = 180°
⇒ 3x° + 60° = 180°
⇒ 3x° = 120°
⇒ x = 40
Substitute found value of x into the expression for ∠LMO:
⇒ ∠LMO = (40 - 10)°
⇒ ∠LMO = 30°
Ray HJ is the angle bisector of angle GHI. The measure of angle IHJ is 32°. What is the measure of angle GHJ?
a: 64°
b: 16°
c: 32°
d: 0.5°
Answer:
c) 32°
Step-by-step explanation:
The bisector of an angle is the line or line segment that divides the angle into two equal parts. So Ray HJ divides ∠GHI into 2 equal parts.
Therefore, ∠GHJ = ∠IHJ
As we are told that ∠IHJ = 32° then ∠GHJ = 32°

Step-by-step explanation:
The values on the given table are presented as follows;
Value of spin: 0,1,2,5,10
Probability: 0.4,0.2,0.2,0.1,0.1
To find the median, we calculate the cumulative probabilities to find the value of the spin art which the cumulative probability is 0.5 as follows;
Cumulative probability, starting from the left, is therefore;
Probability for spin of 0, 0.4 + Probability for spin of 1, 0.2 = 0.6
Therefore, given that the probability of 0.5 occurs within the Value of Spin 1, the median of the probability distribution is 1
The solution is : The median of the distribution is (first option) 1
What is median?In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.
here, we have,
The values on the given table are presented as follows;
Value of spin: 0,1,2,5,10

To find the median, we calculate the cumulative probabilities to find the value of the spin art which the cumulative probability is 0.5 as follows;
Cumulative probability, starting from the left, is therefore;
Probability for spin of 0, 0.4 + Probability for spin of 1, 0.2 = 0.6
