How do you find the circumference of a circle

Answer:

s = 13 - x

t = [tex]\frac{18+x}{2}[/tex]

Step-by-step explanation:

To start out with:

s = 18

t = 18

Sue gives Tony x sweets

s = 18 - x

t = 18 + x

Sue then eats 5 of her sweets

s =  18 - x - 5 = 13 - x

t  = 18 + x

Tony eats half of his sweets

s = 13 - x

t = [tex]\frac{18+x}{2}[/tex]

(Possible constraint that [tex]x\mod 2 = 0[/tex])

When Sue gives Tony x sweets, and then eats 5, she has 13 - x sweets left. Tony, having received x from Sue and then eats half of his total, has 9 + 0.5x sweets.

The question begins with Sue and Tony each having 18 sweets. First, Sue gives Tony 'x' sweets which results in Sue having 18 - x sweets and Tony having 18 + x sweets. Sue then eats 5 sweets resulting in her having 18 - x - 5 = 13 - x sweets. Tony then eats half of his sweets, resulting in him having (18 + x) / 2 = 9 + 0.5x sweets. So, the expressions summarizing the number of sweets Sue and Tony have now are 13 - x for Sue and 9 + 0.5x for Tony respectively.

Answer:

18 meters

Step-by-step explanation:

12 + 6 = 8

Lila travels an absolute altitude difference of 18 meters from home to school, considering she travels from 12 meters below sea level to 6 meters above sea level.

The question presents a situation where Lila travels from an altitude of 12 meters below sea level to an altitude of 6 meters above sea level. Here, instead of adding these two numbers, we consider the absolute values of these heights. Thus, when Lila travels from her home to school, she first climbs up 12 meters to reach sea level and then another 6 meters to reach her school. So, in total, Lila travels 18 meters in altitude when going from home to school.

Step-by-step explanation:

Use the point-slope formula.

y - y_1 = m(x - x_1)    you have :  x_1 =1  and  y_1 =2

m the slope   m= -2 (same slope for the line : 2x+y-1=0 because this lines are parallel and you can write y=-2x-1

Answer:

43°.

Step-by-step explanation:

To find the measures of the other two angles, we will need to use various angle properties.

We can use the Supplementary Angles formula to find the adjacent angle to the angle that measures 123°.

180 - 123 = 57°. This is the measure of the first angle.

Now, to find the measure of the second angle, we know that these are vertical angles meaning they are congruent. Therefore, the measure of the angle is 80°.

To find 'x', we will simply need to subtract from 180:

180 - 80 - 57 = 43°.

Answer:

  x = 2√3 ≈ 3.464

Step-by-step explanation:

The side marked x is opposite the given 30° angle. The side marked 6 is adjacent to that angle. The trig function relating opposite and adjacent sides of a right triangle is ...

  Tan = Opposite/Adjacent

Filling in values, we have ...

  tan(30°) = x/6

Multiplying by 6 gives ...

  x = 6tan(30°) = 6(√3/3)

  x = 2√3 ≈ 3.464

Answer:

65 mph on level road

Step-by-step explanation:

Set b as average speed on the level road  and (b-20) = average speed on the winding road

Distance = speed * time  

Level Road distance + winding road dististance = 285 miles

Substituting b and (b-20), we have,

3b + 2(b-20) = 285

3b + 2b - 40 = 285

5b = 285 + 40

5b = 325

b= 325/5

b = 65 mph on level road

Answer: 52 mph

Step-by-step explanation:

Assume the following :

a = average speed traveled on level road

(a - 20) = average speed traveled on winding road

Recall:

Distance = speed × time

Total distance traveled :

Level road distance + winding road distance = 252 miles

3a + 3(a - 20) = 252

3a + 3a - 60 = 252

6a = 252 + 60

6a = 312

a = 52 mph on a level triad

Answer: 25/676

Step-by-step explanation:

Number of possible outcomes = 26

In other to win, one must draw must be either (A, E, I, O or U)

Therefore required drws to win = 5

First draw:

P(win) = Total required outcome / Total possible outcome

P(win) = 5/26

Second draw:

P(win) = Total required outcome / Total possible outcome

P(win) = 5/26

Therefore,

P(winning twice) = (5/26) × (5/26) = 25/676

The probability of winning the alphabet game twice in a row is 25/676.

To calculate the probability of winning the alphabet game twice in a row, we need to consider the probability of drawing a vowel each time and then multiply these probabilities together since the events are independent.

First, we identify there are 5 vowels (A, E, I, O, U) in the alphabet, and there are 26 total letters. So the probability of drawing a vowel in one turn is 5/26.

To win twice in a row, you would need to draw a vowel during your first turn and then replace the slip and draw a vowel again on your second turn. Since the slip is replaced after each turn, the probability for each turn remains the same (5/26).

Therefore, the probability of winning twice is:

(5/26) * (5/26) = (25/676)

So, the probability of winning the alphabet game twice in a row is 25/676.

Answer:

I will answer it in English:

a) We have te number N = 4752a

if we want to divide it by 3, then the addition of all the digits must be a multiple of 3.

Sum = 4 + 7 + 5 + 2 + a = 6 + 7 + 5 + a = 18 + a

and 18 is a multiple of 3, then we can have, a = 0, a = 3, a = 6, a= 9

b) A number is divisible by 5 if it ends on 5 or 0, so the possible values of a are 0 and 5.

c) we know that 15*3 = 45

then 15*3000= 45000

now we have:

4752a - 45000 = 252a

15*13 = 2520

then we have that a must be equal to zero, and:

15*(13 + 3000) =  47520

d) We want a number that when we divide it by 7, the surpass is 5.

a number is divisible by 7 if the difference between the number without the units and the double of the units is 0 or a multiple of 7.

in N = 4752x the unit is a, then we have:

D = 4752 - 2*x

now, let's choose a such we have a multiple of 7

we know that 5746 is a multiple of 7, so we can choose x= 3 and get:

D = 4752 - 2*3 =   5746  

So the number N = 47523 is a multiple of 7, and when we divide it by 7 we will have a surpass of 0.

Then when we divide N + 5 by 7, we will have a surpass of 7.

This is: N + 5 = 47528

This means that the actual value of a that we need is 8.

Step-by-step explanation:

Final answer:

The sum of 12+12 is an even number because both addends are even numbers, and adding two even numbers always results in an even sum.

Explanation:

The question you're asking is about why the sum of 12+12 is an even number. To answer this, we need to understand a property of even numbers. An even number is any integer that can be divided by 2 without leaving a remainder. Adding two even numbers together will always result in another even number because the sum of two multiples of any number is a multiple of that number. Since 12 is an even number (it can be divided by 2 to get 6), adding it to itself (another even number) must result in an even sum.

It's not correct to say that any number plus 12 is even (Option A) because if you add 12 to an odd number, the result is odd. Option B is the closest to a correct explanation because both addends are equal and are even numbers. Saying any number greater than 12 is even (Option C) is incorrect because odd numbers also exist above 12. Finally, 12+12 is not equal to an odd number (Option D), so that choice is incorrect as well.
