Answer:
1) 3 marbles
2) The number of people born every hour is 9000 people
The number of people born every day is 216,000 people
The number of people born every year = 78,840,000 people
Step-by-step explanation:
1) The given information are;
The number of students = 3 or 6
Amount of marbles remaining after sharing = None
Least amount of marbles that can be shared equally among the students = Condition each student gets one marble = 1 × 3 = 3 marbles
The least amount of marbles that can be shared equally among the students = 3 marbles
2) The number of people born int eh world every minute = 150 people
The number of minute in one hour = 60 minutes
∴ The number of people born every hour = 150 × 60 = 9000 people
Given that the number of hours in one day = 24 hours
∴ The number of people born every day = 9000 × 24= 216,000 people
Given that the number of days in one year = 365 days
∴ The number of people born every year = 216,000 × 365= 78,840,000 people

Step-by-step explanation:
Step 1.
The sample size is the number of numbers. There are 10 of them.
n = 10
The mean is the sum of the numbers (1240) divided by the number of them (10).
[tex]\overline{x}=\dfrac{1240}{10}=124[/tex]

Answer:
[tex]\sin C\approx0.85\\\\\cos C \approx0.52\\\\\tan C\approx1.63[/tex]
Step-by-step explanation:
According to the trigonometric ratios in aright triangle :
[tex]\sin x =\dfrac{\text{Side opposite to x}}{\text{Hypotenuse}}\\\\\cos x =\dfrac{\text{Side adjacent to x}}{\text{Hypotenuse}}\\\\\tan x=\dfrac{\sin x}{\cos x}[/tex]
Given: ΔBCA ~ ΔSTR
Since , corresponding angles of two similar triangles are equal.
So, ∠C = ∠T ...(i) [Middle letter]
In triangle STR
[tex]\sin T=\dfrac{\text{Side opposite to T}}{\text{Hypotenuse}}\\\\=\dfrac{26.4}{30.9}\approx0.85\\\\\cos x =\dfrac{\text{Side adjacent to T}}{\text{Hypotenuse}}\\\\=\dfrac{16.2}{30.9}\approx0.52\\\\\tan T=\dfrac{\sin T}{\cos T}\\\\=\dfrac{0.85}{0.52}\approx1.63[/tex] ...(ii)
From (i) and (ii), we have

How do you prove a parallelogram using these 2 triangles, somebody needs to explain this to me?
RQP=ONP
Since R is the midpoint of MQ, then MR and RQ are equal.
Since R is the midpoint of MQ, then P must be the midpoint of NQ
The triangles are congruent and the trapezoid is three or those triangles.
RQR reflected is a triangle inside the trapezoid. The triangles at the left and right of the trapezoid are congruent.
Since all the triangles are the exact same, then they have the same height and same length.
So you connect them without like sliding a triangle up a little bit.
The 4 congruent triangles add up to be a parallelogram.

A party mix is made by adding nuts that sell for $2.50 per kg to a cereal mixture that sells for $1 per kg. How much of each should be added to obtain 60 kg of a mix
that will sell for $1.40 per kg?
1. The amount of nuts is ____kg and cereal mixture is ____ kg to obtain 60 kg of a mix that will sell for $1.40 per kg.
Answer:
The amount of nuts is 16 kg and cereal mixture is 44 kg to obtain 60 kg of a mix that will sell for $1.40 per kg
Step-by-step explanation:
Let
x=nuts at $2.50 per kg
y=cereal at $1 per kg
x+y=60 kg (1)
2.50x+y=1.40(60) (2)
From (1)
x=60-y
Substitute x=60-y into (2)
2.50x+y=1.40(60)
2.50(60-y)+y=84
150-2.5y+y=84
-1.5y=84-150
-1.5y=-66
Divide both sides by -1.5
y=44 kg
Substitute y=44 into (1)
x+y=60
x+44=60
x=60-44
=16
x=16 kg

Which of the following equations have exactly one solution? Choose all answers that apply: A.6x-15=6x+15 B.6x-6=6x+15 C.6x+15=6x+15 D.6x-6=15x+15
Answer: D
Step-by-step explanation:
In every other solution, x gets canceled out, so it has no impact on the equation. Thus, A, B, and C all have either infinite or no solution, because they have 6x on both sides of the equation.
Further proof:
6x-6=15x+15
Add(6)
6x=15x+21
Subtract(15x)
-9x=21
Divide(-9)
x = -2 3/9
Hope it helps <3
Answer:
d) 6x - 6 = 15x + 15
Step-by-step explanation:
Well let’s solve.
a)
6x - 15 = 6x + 15
Lets use the communicative property which is the moving of numbers.
We can start with -15, so we do +15,
6x = 6x + 30
Then we can do -6x
0 = 30
This is a false statement meaning there is no solution.
b)
6x - 6 = 6x + 15
We can start by doing +6
6x = 6x + 21
-6x
0 = 21
Again, this is a false statement meaning this has no solutions.
c)
6x + 15 = 6x + 15
So we do -15
6x = 6x
If this is the case then there is infinitely many solutions.
d)
6x - 6 = 15x + 15
So we can start by doing +5p6
6x = 15x + 21
Then we can do -15x
-9x = 21
then we can do 21 / -9 which is -2 1/3.
x = -2 1/3
So this has one solution.
Which could be the areas of the smaller squares?
Answer:
A, BStep-by-step explanation:
We have a right triangle. Therefore, we can use the Pythagorean theorem:
The sum of the areas of the squares built on the legs is equal to the area of the square built on the hypotenuse.
We have the area of the largest square (the square built on the hypotenuse).
A₃ = 36 u²
From the Pythagorean therem we have the equation:
A₃ = A₁ + A₂
We need the areas of the smaller squares (A₁ and A₂).
A₁ + A₂ = 36.
From the second picture, we have:
A) 6 and 30 → 6 + 30 = 3 CORRECT
B) 8 and 28 → 8 + 28 = 36 CORRECT
C) 4 and 16 → 4 + 16 = 20 ≠ 36 INCORRECT

Answer:
5
Step-by-step explanation:
When squaring the number 5 (i.e [tex]5^2[/tex] ) the answer is 25. [tex]5^{2}[/tex] is the same thing as 5 times 5. Basically with the square root, you are going backwards, so you are therefore finding the base of it all.
We have a square that has area of 25 square units. The question is: what is the side length? That would be 5 since 5*5 = 25. You would use guess and check if you weren't familiar with square roots. A better option is to use the square root function on the calculator.
Note: the square root undoes the squaring operation
Can someone help me find the sequence
Answer: the answer is b, thank me later
Answer:
The answer is option A
Step-by-step explanation:
The formula is
[tex]a(n + 1) = a(n) + 6[/tex]
a(1) = 11
The second term will be
a( 1 + 1) = a(1) + 6
a(2) = 11 + 6
= 17
The next term will be
a( 2 + 1) = a(2) + 6
a(3) = 17 + 6
= 23
The next term will be
a(3 + 1) = a(3) + 6
a(4) = 23 + 6
= 29
The next term will be
a(4 + 1) = a(4) + 6
a(5) = 29 + 6
= 35
So the sequence is
11 , 17 , 23 , 29 , 35
Hope this helps you

(x + 4y – z = 5
2(3x – 2y + 2z = 7 )
6x - 4y + 4z = 14
7x + 3z = 19
3(2x – z= -2)
6x - 3z = -6
13x = 13
x = 1
6(1) - 3z = -6
-3z = -12
z = 4
(1) + 4y - 4 = 5
4y = 8
y = 2
ΔABC is similar to ΔMNO. The scale factor from ΔMNO to ΔABC is 3∕2. If the perimeter of ΔMNO is 25 units, what's the perimeter of ΔABC? Question 20 options: A) 225 units B) 37.5 units C) 25 units D) 150 units
Answer:
b)37.5
Step-by-step explanation:
the ratio 3:2 is the same as 1.5, so you multiply 1.5 & 25 to get 37.5 units
The required measure of the perimeter of the ΔABC is 37.5 units. Option B is correct.
Given that,
ΔABC is similar to ΔMNO. The scale factor from ΔMNO to ΔABC is 3∕2. If the perimeter of ΔMNO is 25 units, what's the perimeter of ΔABC?
The scale factor is defined as the ratio of the modified change in length to the original length.
Here,
3/2ΔMNO = ΔABC
The perimeter of the ΔABC = 3/2 The perimeter of the ΔMNO
The perimeter of the ΔABC = 3 / 2 [25]
The perimeter of the ΔABC = 37.5
Thus, the required measure of the perimeter of the ΔABC is 37.5 units. Option B is correct.

what are fractions that are equivalent to 4/20?
Answer: 1/2, 2/10, and 3/15
Explanation: Let's find 3 fractions that are equivalent to 4/20.
To find 3 fractions that are equivalent to 4/20,
notice that 4/20 is not in lowest terms.
In this situation, let's first rewrite 4/20 so that it's in lowest terms.
To do this, we divide the numerator and denominator by the
greatest common factor of 4 and 20, which is 4, and we have 1/5.
Since 1/5 is equivalent to 4/20, we can use
1/5 to find more equivalent fractions.
If we multiply 1/5 by 2 in both the numerator and
denominator, we get the equivalent fraction 2/10.
If we multiply 1/5 by 3 in both the numerator and
denominator, we get the equivalent fraction 3/15.
So 4/20 is equivalent to 1/5, 2/10, and 3/15.
Note that these are just 3 possible answers.
There are many other fractions that are also equivalent to 4/20.

Identify if the sequence is arithmetic or geometric. Then find the next number in the sequence? 1.9, 4.9, 7.9, 10.9, 13.9, ...
Answer:
arithmetic; d = 3; 16.9
Step-by-step explanation:
4.9 - 1.9 = 3
7.9 - 4.9 = 3
10.9 - 7.9 = 3
13.9 - 10.9 = 3
--
13.9 + 3 = 16.9
Answer:
1. Arithmetic 2. 16.9
Step-by-step explanation:
To solve this problem you will need to know the difference between an arithmetic and a geometric.
An arithmetic is a sequence where a person is adding the same number over and over again so lets say you start with 1 and the common difference (the number being added each time) is 2, the sequence will look something like this 1, 3, 5, 7, 9 and so on.
A geometric sequence is when the same number is being multiplied over and over again. So lets say that the number we start with is 2 and you are multiplying by three every single time, so you would get a sequence looking like this 2, 6, 18, 54 and so on.
We can see in the sequence that the number that is being added over and over again is 3 so the first answer is arithmetic.
Now that we know that the sequence is arithmetic and the common difference is 3 we can plug that into the equation and we will see that 13.9 + 3 is 16.9

D 5
E 2
a) Find the theoretical probability that the spinner lands on A or E. b) Find the experimental probability that the spinner lands on A or E. c) Explain why the probabilities are different.
a) The theoretical probability of landing on A or E is 2/5. This is because there are two sections we want to land on (either A or E) out of 5 sections total.
--------------------------
b) The empirical probability of landing on A or E is 3/10, which was reduced from 6/20. This is because there are 4+2 = 6 times we landed on either A or E out of 20 spins total.
--------------------------
c) Due to the nature of random events, the theoretical and empirical probabilities will not match up perfectly (basically every random experience will be different for each person). This is especially true for small sample sizes. However, as you do more spins, you should find that the empirical probabilities will slowly approach the theoretical probability. The theoretical probability is always going to be 2/5 for this problem; while the empirical probabilities will bounce around because of the nature of random chance.

the number of new cars purchased can be modeled by the equation, c=20t^2+135t+3050, where C is the number if new cars and t=0 corresponds to the number of new cars purchased in 1998. in what year will the number of new cars purchased reach 15,000
Answer:
In the year 2019 the number of new cars purchased will reach 15,000.
Step-by-step explanation:
t = 0 corresponds to the number of new cars purchased in 1998. If that is so, we can determine t ( time ) by making our quadratic equation here equal to 15,000 - considering that we want the year the number of cars reaches this value. t here is only the number of years to reach 15,000 cars, so we would have to add that value to 1998, to see the year that the cars will reach 15,000.
The " set up " should look like the following quadratic equation -
20t² + 135t + 3050 = 15,000 - Isolate 0 on one side,
20t² + 135t - 11950 = 0 - From here on let us solve using the quadratic equation formula,
[tex]t=\frac{-135+\sqrt{135^2-4\cdot \:20\left(-11950\right)}}{2\cdot \:20}:\quad \frac{-27+\sqrt{38969}}{8}[/tex],
[tex]t=\frac{-135-\sqrt{135^2-4\cdot \:20\left(-11950\right)}}{2\cdot \:20}:\quad -\frac{27+\sqrt{38969}}{8}[/tex] ... now as you can see we have two solutions, but time can't be negative, and hence our solution is the first one - about 21.3 years. 1998 + 21.3 = ( About ) The year 2019. Therefore, in the year 2019 the number of new cars purchased will reach 15,000.
Answer:
2019
Step-by-step explanation:
first you should change the statement into quadratic equation and replace c with 15000.
c=20t^2+135t+3050.
15000=20t^2+135t+3050
15000-3050=20t^2+135t
11950=20t^2+135t. then write the equation in standard quadratic form.
20t^2+135t-11950=0. after this you got 4 ways of solving the quadratic equation but I am just gone using quadratic formula:
-b+ - √b^2-4ac. a,b and C stand for the
2a. the coefficients
-135+ - √((135)^2-4(20)(-11950))
2(20)
-135+ - √(974225))
)) 40
-135 - 987 or -135+ 987
40. 40
-1122/40. or 852/40
- 28.05 or. 21.3
in this case we have to answer but time cannot be negative we take value 21.3(it is the approximate value)
so we add 21.3 to 1998 to find the year
>>21.3 + 1998 = 2019.3 but we write it as 2019 instead of 2019.3
