A quadrilateral has two angles that measure 190° and 10°. The other two angles are in a ratio of 3:5. What are the measures of those two angles?
Answers
Answer:
60 degrees and 100 degrees
Step-by-step explanation:
360 - (190 + 10) = sum of other two angles
360 - 200 = 160
160/(3+5) = 160/8 = 20
20 × 3 = 60 degrees, 20 × 5 = 100 degrees
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.
Answers
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 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.
Answers
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

ײ - 6x= -58
Substitute the values of a and b to complete the sonlutions
x= a+bi
x=a -bi
Answers
Answer:
x = 3 + 7i or x = 3 - 7i; a = 3; b = 7
Step-by-step explanation:
x^2 - 6x = -58
We complete the square by adding the square of half of the coefficient of the x-term to both sides.
x^2 - 6x + 9 = -58 + 9
(x - 3)^2 = -49
[tex] x - 3 = \pm 7i [/tex]
x = 3 + 7i or x = 3 - 7i
a = 3; b = 7
The required value of a and b for the solution of the given equation is 3 and 7 respectively.
Given that,
To determine the solutions of this quadratic equation x² - 6x= -58 and Substitute the values of a and b to complete the solution.
x= a+bi
x=a -bi
The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
Given equation,
x² - 6x= -58
Completing the square of the above equation by adding and subtracting the square of the half of the coefficient of x.
x² - 6x + 9 - 9 = -58
(x - 3)² = -58 + 9
(x - 3)² = -49
x - 3 = √-49
x - 3 = ±7i
x = 3 ±7i
Now,
The required
a + bi = 3 + 7i
a - bi = 3 - 7i
Thus the required value of a and b for the solution of the given equation is 3 and 7 respectively.

The graph is showing the quadratic function.
What is Quadratic function?A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree. A quadratic function must have at least one second-degree term. It performs algebraic operations.
As, the linear function have graph consist of straight line.
Then, The quadratic function has the shape of a parabola and has the variable squared.
and, exponential function have raising curve or falling curve.
As, per the given graph the curve shows parabola which is quadratic in nature.

find the area and perimiter of the figure, given that AB is a semi-circle that has the length 24 π cm
Answers
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.

A stock valued at $100 decreases in value by 9.5% each year? What is the function?
Answers
Answer:
the function is y= 100-0.095x
Step-by-step explanation:
Step one:
given data
A stock valued at $100 decreases in value by 9.5%
let the number of years be x
Step two:
Hence, the rate of decrease is 0.095
therefore the function is
y= 100-0.095x
The function which represents the situation is
[tex]f(x) = 100 - {0.95}^{x} [/tex]
How to write exponential functionoriginal value of stock = $100Percentage decrease per year = 9.5%
= 9.5/100
= 0.095
Number of years = xf(x) = 100 - 0.095^x
[tex]f(x) = 100 - {0.95}^{x} [/tex]
Therefore, the function which represents the situation is f(x) = 100 - 0.095^x

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?
Answers
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%
