Answer:
Each friend will receive 210.5 dollars.
Step-by-step explanation:
Total Amount Tyion has = 4,000 dollars
He wants to share evenly with 19 friends.
We need to find How much would amount each friend will receive.
We can found it by using formula:
Amount each friend received = Total Amount / Number of friends
Putting values in the formula and finding results:
Amount each friend received = 4000/19
Amount each friend received = 210.5 dollars
So, each friend will receive 210.5 dollars.
A farmer wants to estimate the average growth in height of his corn plants over a two-week period. Of his 5,000 plants, 1,500 are on plots where he grew corn last year, 3,000 are on plots where he grew soybeans last year, and 500 are plots where nothing but grass grew last year. The farmer wants to use a stratified sample of 200 plants based on what grew on the plots the year before. How many plants from plots where he grew corn last year should be included in his sample? Enter a whole number.
Answer:
60
Step-by-step explanation:
Given that :
Total crop on corn plot = 1500
Total on soya bean plot = 3000
Total on grass plot = 500
Total plants = 5000
A Stratified sample of 200 corn plants is to be selected ;
Number of samples he takes from each plot:
Percentage of number of samples :
x% of 5000 = 200
0.01x * 5000 = 200
50x = 200
x = 200/50
x = 4%
Hence, number of plants to be selected from corn plot :
4% of 1500
0.04 * 1500
= 60

A system of two equations is shown.
2 + 2y = 6
2x - 3y = 26
What is the solution of the system?
0 (-2,3)
(1, -2)
O (-2.4)
(10.-2)
Answer:
Please check the explanation.
Step-by-step explanation:
Given the system of equations
2 + 2y = 6
2x - 3y = 26
Let us solve the system of equations
[tex]\begin{bmatrix}2+2y=6\\ 2x-3y=26\end{bmatrix}[/tex]
Rearrange equations
[tex]\begin{bmatrix}-3y+2x=26\\ 2y=4\end{bmatrix}[/tex]
Multiply -3y+2x=26 by 2: -6y+4x=52
Multiply 2y = 4 by 3: 6y = 12
[tex]\begin{bmatrix}-6y+4x=52\\ 6y=12\end{bmatrix}[/tex]
adding the equations
[tex]6y=12[/tex]
[tex]+[/tex]
[tex]\underline{-6y+4x=52}[/tex]
[tex]4x=64[/tex]
Solve 4x = 64 for x
[tex]4x = 64[/tex]
divide both sides by 4
[tex]\frac{4x}{4}=\frac{64}{4}[/tex]
Simplify
[tex]x = 16[/tex]
For -6y+4x = 52 plug in x = 16
[tex]-6y+4\cdot \:16=52[/tex]
Multiply the numbers: 4 · 16 = 64
[tex]-6y+64=52[/tex]
Subtract 64 from both sides
[tex]-6y+64-64=52-64[/tex]
Simplify
[tex]-6y=-12[/tex]
Divide both sides by -6
[tex]\frac{-6y}{-6}=\frac{-12}{-6}[/tex]
[tex]y=2[/tex]
Therefore, the solution to the system of equations be:
[tex]y=2,\:x=16[/tex]
Thus,
(x, y) = (16, 2)

Kiara invested $3,500 into two accounts. One account paid 5% interest and the other paid 7.5% interest. She earned 6%
interest on the total investment. How much money did she put in each account?
Answer:
A=$2100
B=$1400
Step-by-step explanation:
3500*1.06=3710
a+b=3500
1.05a+1.075b=3710
1.05a+1.05b=3675
1.05a+1.075b=3710
Subtract 1.05a+1.05b=3675 from 1.05a+1.075b=3710
0.025b=35
b=1400
a=3500-1400=2100
Double check: (2100*1.05)+(1400*1.075)=3710
3500*1.06=3710
The amount invested in the account that pays a 5% interest is $2100 and the amount invested in the account that pays a 7.5% interest is $1400.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
0.05a + 0.075b = (0.06 x $3500)
0.05a + 0.075b = $210 ----- equation 1
a + b = $3,500 -------- equation 2
Where:
a is the amount invested in the account that paid a 5% interest.
b is the amount invested in the account that paid a 7.5% interest.
The amount invested in the account that pays a 7.5% interest.
In order to determine this value, multiply equation 2 by 0.05
0.05a + 0.05b = 175 ------- equation 3
0.025b = 35
b = $1400
The amount invested in the account that pays a 5% interest.
a + $1400 = $3500
a = $3500 - 1400
a = $2100
Therefore, The amount invested in the account that pays a 5% interest is $2100 and the amount invested in the account that pays a 7.5% interest is $1400.

find the area and perimiter of the figure, given that AB is a semi-circle that has the length 24 π cm
Answer:
Perimeter ≈ 61.68, Area ≈ 226.08
Step-by-step explanation:
The original equations for a regular circle are as follows:
Circumference = 2πr
Area = πr^2
With these in mind, let us continue. We must first find the Circumference and Area of a circle with this radius. To do this we plug in the radius which we can derive from taking the length of the semi-circle. Dividing 24/2 will give us 12 which is the radius. Evaluating both equations with r = 12 and π = 3.14 will give us Area = 452.16 and Circumference = 75.36. Great, we now have the values we need. However, this is for a full circle, and we are trying to solve for a semi-circle. To resolve this, all we have to do is divide the Area by 2 and that will give us half of that circle (the semi-circle). For the Circumference, we divide by 2 as well, but we also must add the diameter which is 24 giving us 226.08, and 61.68 respectively.

Answer:
[tex](a):\ y = \frac{x + 3}{7}[/tex] --- Function
[tex](b):[/tex] Not a function
[tex](c):[/tex] A function
Step-by-step explanation:
Given

Required
Determine if each relation is a relation or not
A function is represented as: [tex]\{(x_1,y_1),(x_2,y_2),(x_3,y_3)...(x_n,y_n)\}[/tex]
Where
[tex]x = domain[/tex] and [tex]y = range[/tex]
For a relation to be a function:
No x value (in other words, the domain) must be repeated
[tex](a):\ y = \frac{x + 3}{7}[/tex]
The above relation is a function. This is so because every unique value of x have a unique value of y.
In other words:
No two domains exist for a range
Conclusively, it is a one-to-one function
[tex](b):[/tex]
[tex]\begin{array}{ccccc}x & {-2} & {-2} & {1} & {3} \ \\ y & {-5} & {-1} & {3} & {7} \ \ \end{array}[/tex]
In the above table, we have:
[tex](x_1,y_1) = (-2,5)[/tex] and [tex](x_2,y_2) = (-2,-1)[/tex]
The domain (-2) points to range (5 and -1).
Based on the condition that no two domain should point to the same range, we can conclude that this is not a function.
[tex](c):[/tex]
[tex]\begin{array}{ccccc}x & {-3} & {-1} & {1} & {3} \ \\ y & {-4} & {-4} & {2} & {2} \ \ \end{array}[/tex]
In the above table, we have the domain to be:
[tex]x = \{-3,-1,1,3\}[/tex]
We can see that no x value is repeated.
Hence, this is a function.

A jar contains 30 red marbles, 50 blue marbles, and 20 white marbles. You choose one marble from the jar at random. What is the theoretical probability of choosing a red marble?
Answer:
you have a 1/5 chance of choosing a red marble.
Step-by-step explanation:
Answer:
Your probability of choosing a red marble is 30%
Step-by-step explanation:
You'll need to start by adding all the marble's which will give you 100.
30 + 50 + 20 = 100
Then add up the non-red marbles, which is 70.
50 + 20 = 70
30 red marbles are left.
Now, you'll have the fraction 30 over 100.
As a percentage that would be 30%

DETERMINA EL VOLUMEN DE UN PRISMA PENTAGONAL QUE TIENE LAS SIGUIENTES MEDIDAS: LADO 6.1 CM, APOTEMA 4.5, ALTURA 12.5CM DEL PRISMA
Answer:
837.23 cm³
Step-by-step explanation:
La fórmula para el volumen de un prisma pentagonal se da como:
1/2 (5 s × a) × h
Dónde:
s = longitud lateral
a = Apotema
h = altura
De la pregunta anterior:
s = largo de lado = 6.1 cm
a = Apotema = 4.5 cm
h = Altura = 12.5 cm
Por lo tanto:
El volumen del prisma pentagonal =
1/2 (5 × 6.1 × 4.5) × 12.5
= 1/2 × 137.25 × 12.5
= 837.225 cm³
Aproximadamente = 837.23 cm³

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the
ranslation?
O(x, y) = (x + 5, y-3)
O (X,Y) - (x + 5, y + 3)
O(x, y) = (x-3, y + 5)
(x, y) = (x + 3, y + 5)
Answer:
A rectangle on a coordinate plane is translated 5 units up and 3 units to the left.
3) O(x,y)=(x-3,y+5)
The rule that describes the translation is (x, y) -> (x - 3, y + 5), the correct option is C.
How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units:
y=f(x+c) (same output, but c units earlier)
Right shift by c units:
y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y =[tex]k \times f(x)[/tex]
Horizontal stretch by a factor k: y = [tex]f\left(\dfrac{x}{k}\right)[/tex]
We are given that;
5 units up and 3 units to the left
Now,
In this case, the rectangle is translated 5 units up and 3 units to the left. This means that the vertical shift is 5 and the horizontal shift is -3.
After transformation x=x - 3
Y=y + 5
Therefore, the transforming function will be (x, y) -> (x - 3, y + 5).

A student club spends $78 to buy candy bars and sells them for $3 each to raise money. Construct an equation that models profit or loss for selling a given number of candy bars.
Answer: 3x - 78
Step-by-step explanation:
Profit or loss is gotten when the cost is subtracted from the revenue. In this situation, the revenue is given as $78.
Let the total number of candy bars bought be x. Since they are sold at $3 each, all the candy bars will cost 2x.
Profit/Loss = Revenue - Cost
= 3x - 78
If we get a negative value, that's a loss and a positive value denotes profit
