Answer:

Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called (Pi).

Step-by-step explanation:

Answer:

The relationship between the Circumference of a circle and the diameter of the circle is that The circumfrence depends on the outside of the circle and around. Diameter depends on the Inside from side to side completely.

Step-by-step explanation:

The formula to find circumference : C= Pi x d or 3.14 x diameter.

The formula to find the circle's diameter is R x 2 or Radius x 2

Becuase the radius is half of a diameter so to find diameter in the radius just multiply by two and you have your answer.

Answer:

A.) 193

B.)191

C.)236

D.)128

Step-by-step explanation:

A)   12^2+(8-4)^3-15

Answer:

A=61 ; B=56 ; C=45

Step-by-step explanation:

I don't understand the question, but this is my answer.

Step-by-step explanation:

you must have misunderstood. a mile is much longer than a kilometer.

so, the relation is correctly (but still only roughly)

8 kilometers = 5 miles

100 km = 8×x km

x = 100/8 = 25/2 = 12.5

now, we need to apply the same factor to 5 miles

5×12.5 miles = 62.5 miles per hour

so, 100 km/h = 62.5 miles/h

now, if the relation would truly be

8 miles = 5 kilometers

then

100 km = 5×x km

x = 100/5 = 20

now we apply the same factor to the miles and get

8×20 miles = 160 miles

and 100 km/h = 160 miles/h

but it is not.

these would be the correct numbers, if we asked what a speed limit of 100 miles per hour would be in kilometers per hour.

and yes,

100 miles/h = 160 km/h

Answer:

x=-6

QUESTION 31

Step-by-step explanation:

3x+5=2x-1

Subtract 5 from both sides

3x+5-5=2x-1-5

Simplify

3x=2x-6

Subtract 2x from both sides

3x-2x=2x-6-2x

QUESTION 32

1/3(6x+12) = 1/2(4x-8) + 8

1/2(4x-8) = 4x-8/2 +8

1/3(6x+12) = 4x-8/2 +8

2(6x+12) = 12(x-2) + 48

12x+24

12x+24 = 12x+24

12x+24 - 24 = 12x+24 - 24

12x=12x

0=0

Answer:

b = 142

Step-by-step explanation:

A = 38

B = ?

Total degree of line: 180

We will first subtract 38 off of 180 as seen below

180 - 38

Once we do that we will figure out what B equals.

180 - 38 = 142

Answer:

The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer. The property holds for Addition and Multiplication, but not for subtraction and division.

Answer:

$64.40

Step-by-step explanation:

Given:
Pitcher sells for $46.00

Marked up 40%

Note:

Marked up = Increase

40% = .40

Solve:

46.00 x .40=18.40

46.00 + 18.40 = $64.40

Hence, Cost of the pitcher = $64.40

Answer:

Triple the square of a number is represented as:

⭐ Let "x" be the unknown number , we express:

Triple a number: 3x

The square of a number: x²

So, the expression for "Three times the square of a number" is:

3x²

The mathematical language uses algebraic expressions (numbers or letters) united by basic operations such as addition, subtraction, multiplication, and division.

Answer: the answer is c: 5x+2y+z

Step-by-step explanation: There are 5 x's 2 y's and 1 z so you add all of them up to get the answer for your expression

Answer:

a) 120

Explanation:

y is 100%

x is 130%

solve:

130% ↔ 520

100% ↔ (520/130)*100

100% ↔ 400

the X - Y:

520 - 400

120

Answer:

So triple a number means 3y. The difference (use minus symbol) of triple a number and 5 should be written as 3y - 5. Example 3: The sum of the quotient of m and 2, and the product of 4 and n. Answer: In this case, the unknown numbers are already provided as m and n.

Answer:

7

Step-by-step explanation:

the median is the value in the middle of all measured data points in that sense that half of the other data points are smaller, and half of the other data points are bigger.

if there are 2 middle numbers (because we have an even number of data points), then the mean value between these 2 middle numbers is then the median.

in order to find the median, we need to sort the data points first (best from small to large) :

4, 5, 5, 6, 7, 7, 7, 8, 8, 9, 9, 10

since these were the passing students, we know that the marks of the not passing students must be below that. so that our sorted list looks like

m1, m2, m3, 4, 5, 5, 6, 7, 7, 7, 8, 8, 9, 9, 10

now we have 15 data points, so the median is the data point with 7 left and 7 right of it : 7

Answer:

$50

Step-by-step explanation:

The discount percentage was 36%. This means that $32 is 64% of the original cost.

Divide $32 by 64%: (32/.64= 50)

The original cost was $50.

Answer:

Step-by-step explanation:

1) with the angle 120degrees, we know that external angles on a pair of parallel lines are the same. we can give this as an equation  

120 = x + 130

re arrange to make x the subject

so subtract 130 on both sides

120-130=x

-10=x

x=-10

2) Corresponding angles in between parallel lines are the same. we can write this as

15x = 75

rearrange to make x the subject

x = 75 ÷ 15

x = 5

3)Internal angles inbetween parallel lines add to 180, so we can turn this into an equation

14x - 3 = 85

14x = 88

x = 88 ÷ 14

x = 6.285714 or just 6.29

Hello.

First of all, let the number be t.

The product of 5 and t is written like so:

[tex]\mathrm{5t}[/tex]

9 increased by means we add 9, so let's add 9 to 5t:

5t+9

Now, this expression is greater than or equal to -18:

[tex]\mathrm{5t+9\geq -18}[/tex]

Therefore, the final answer is:

[tex]\mathrm{5t+9\geq -18}[/tex]

I hope it helps.

Have a nice day.

Step-by-step explanation:

there are different many numbers

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
