Which of the following represents the relationship between the circumference, c, and diameter, d, of any circle?
Given:
Circumference of a circle = C
Diameter of a circle = d
To find:
The relationship between the circumference, c, and diameter, d, of any circle.
Solution:
We know that, circumference of a circle is
[tex]C=2\pi r[/tex]
It can be written as
[tex]C=(2r)\pi [/tex]
[tex]C=d\pi [/tex] [tex][\because d=2r][/tex]
On dividing both sides by d, we get
[tex]\dfrac{C}{d}=\pi [/tex]
Therefore, the correct option is (F).

is 3.12311 a rational number
All terminating decimals are rational numbers
In this case,
3.12311 = 312311/100000
which shows that 3.12311 can be written as a ratio of two integers, therefore making it a rational number.
Tyrese wants to buy 15 packs of baseball cards. They cost $ 5.00 per pack. There is a 25 % discount before tax if 10 or more packs are purchased. Sales tax is 7 % . Tyrese gives the cashier $ 100 to pay for his baseball cards. How much change will he receive in return?
Answer:
Tyrese will receive $39.81 in return.
Step-by-step explanation:
First, you have to multiply the 15 packs for the cost per pack:
15*$5=$75
As there is a 25% discount before tax if 10 or more packs are purchased, you have to calculate 25% of the total cost for the 15 packs and subtract that amount from the cost:
$75*25%=$18.75
$75-$18.75=$56.25
Then, you have to calculate 7% of the amount with the discount and add that to the cost:
$56.25*7%=$3.93
$56.25+$3.94=$60.19
Now, you can subtract $60.19 from $100 to find the change that Tyrese will receive in return:
$100-$60.19= $39.81
According to this, the answer is that Tyrese will receive $39.81 in return.

Which angle is coterminal with a 635° angle?
A. An angle measuring 85°
B. An angle measuring 275°
C. An angle measuring 255°
D. An angle measuring 335°
Answer:
B.
Step-by-step explanation:
the answer is B bevause you subtract 635 and 360, and then you get 275.
An angle measuring 275° is coterminal with a 635° angle.
What is Coterminal angles?This classification represents angles that do not present the same value, but they present vertices and sides are identical. Also, if the angles are coterminal, then their sines, cosines and tangents are equal.
here, we have,
we know that,
A coterminal angle can be found from the formula β = α ± 360 * w, where w is a positive integer.
Thus,
For w=1 and α=635°
β = 635° ± 360 * 1
β = 635° ± 360
Then, β can be 635°+360=995° or 635°-360= 275°
For w=2 and α=635°°
β = 635° ± 360 * 2
β = 635° ± 720
Then, β can be 635°+720=1355° or 635°-720= -85°
Therefore, the answer to this question is option B.

Answer:
The correct options are;
1. Definition of supplementary angles
2. m∠1 + m∠2 = m∠1 + m∠3
3. m∠2 = m∠3
4. Definition of Congruent Angles
Step-by-step explanation:
The two column proof is presented as follows;
Statement [tex]{}[/tex] Reason
1. ∠1 and ∠2 are supplementary [tex]{}[/tex] Given
[tex]{}[/tex] ∠1 and ∠3 are supplementary
2. m∠1 + m∠2 = 180° [tex]{}[/tex] Definition of supplementary angles
[tex]{}[/tex] m∠1 + m∠3 = 180°
3. m∠1 + m∠2 = m∠1 + m∠3 [tex]{}[/tex] Transitive Property
4. m∠2 = m∠3 [tex]{}[/tex] Subtraction Property of Equality
5. ∠2 ≅ ∠3 [tex]{}[/tex] Definition of Congruent Angles
Given that angles ∠1 and ∠2 are supplementary angles and angles ∠1 and ∠3 are are also supplementary angles, then the sums of m∠1 + m∠2 and m∠1 + m∠3 are equal, therefore, ∠2 and ∠3 have equal quantitative value and therefore ∠2 = ∠3 and by definition, ∠2 ≅ ∠3.
En una tienda venden pepitas de chocolate y nueces. 2 libras de pepitas de chocolate y libras de nueces cuestan $20 en total. 8 libras de pepitas de chocolate y 3 libras de nueces cuestan $29 en total. Hallar cuánto cuesta cada libra de pepitas de chocolate y cada libra de nueces.
Responder:
$ 2.5 y $ 3
Explicación paso a paso:
Paso uno:
datos dados
Sea xey el costo por libra de chispas de chocolate y nueces, respectivamente
por lo tanto
2x + 5y = 20 ------ 1
y
8x + 3y = 29 ------ 2
resolviendo 1 y 2 simultáneamente tenemos
2x + 5y = 20 (multiplicar la ecuación por 4)
8x + 20y = 80 ------------- 3
restar eqn 2 de 3
8x + 20y = 80 ------------- 3
8x + 3y = 29 ----------------- 2
0 + 17 años = 51
divide ambos lados por 17
y = 51/17
y = 3
El costo de las nueces por libra = $ 3
poner y = 3 en 8x + 3y = 29 ------ 2
8x + 3 (3) = 29 ------ 2
8x + 9 = 29
8x = 29-9
8x = 20
divide ambos lados entre 8
x = 20/8
x = 2,5
El costo del chocolate por libra = $ 2.5
Write an inequality that represents the graph.
Answer:
[tex]y - 2x - 1 = 0[/tex]
Step-by-step explanation:
the slope is :
[tex] \tan( \alpha ) = 4 \div 2 = 2[/tex]
at a pt on graph , when
[tex]x = 1 \\ y = 3 \\ [/tex]
therefore, coordinates are (1,3)
The equation is :
[tex](y - 3) = slope \times (x - 1) \\ (y - 3) = 2 \times (x - 1) \\ y - 3 = 2x - 2 \\ y - 2x - 1 = 0[/tex]
3 drinks and 2 pretzels costs $16, but 6 drinks and 5 pretzels ests $21.25. What is the press
of one pretzel?
Answer:
The price of one pretzel is $-10.75
Step-by-step explanation:
I'm not really sure why the pretzel would be negative dollars, but I checked my answer multiple times and it's right. For this problem you need a system of equations. The system will be 3d+2p=16 (since 3 drinks and 2 pretzels is 16 dollars) and 6d+5p=21.25 (since 6 drinks and 5 pretzels is 21.25 dollars). To solve this system, the first thing we're going to do is multiply the first system by -2 so that we can cancel the d variable. This will leave you with
-6d-4p=-32. Now, you can add this to the other equation. Since the -6 and 6 cancel, we only have the p variable now (that's why we multiplied by -2, to cancel out the d variable when we added later). Now we have -4p=-32 and 5p=21.25. Add these two equations together and you'll get 1p=-10.75, or p=-10.75. If you needed to solve for the drinks, you could plug -10.75 back into one of the first two equations, but for this problem we don't so -10.75 is your answer.

Answer:
a° = 124°
Step-by-step explanation:
Angle E + 250° = 360 because they make a full angle
a° + 126° + E = 360°
a° = 360 - 126 - 110
a° = 124°
Answer:
a=125°
Step-by-step explanation:
The angle at E=360-250=110°
Draw a horizontal through E, parallel to AB and CD such that it divides angle E into two angles of 55° each. Produce line AB to M such that the 55° at E is alternate with it.
A and 55° are now supplementary angles therefore
a+55°=180°
a=180-55=125°
There are 800 students in a school and 45% of
the students are male. If 30% of the male students
and 25% of the female students play varsity sports,
how many students play varsity sports?
Answer:
218
Step-by-step explanation:
No. of male students = [tex]\frac{45}{100}[/tex] × 800
= 360
No. of male students that play varsity sports = [tex]\frac{30}{100}[/tex] × 360
= 108
------------------------------------------------------------------------------------------------------------
No. of female students = 800 - 360
= 440
No. of femal students who play varsity sports = [tex]\frac{25}{100}[/tex] × 440
= 110
Total no. of students who play varsity sports = 108 + 110
= 218
