A farmer harvested 250 fruits. 82 were oranges and there were twice as many sapodillas as paw paws. What percentage of the fruits were paw paws? ||giving 30 points
Answer:
22.4%
Step-by-step explanation:
There were twice as many sapodillas as paw paws--take the sapodillas as 2 units and paw paws as 1 unit.
Form an equation.
2u + 1u + 82 = 250
Simplify and solve for 1 unit.
3u = 168
1u = 56
Number of paw paws is 56.
Formula for finding percentage of an object is given as (number of object/total number of items) x 100.
Percentage of paw paws
= (56/250) x 100
= 22.4%
HELP PLS Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
The slope of the line is the ratio of the rise to the run, or rise divided by the run. slope of line is 4/3.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given two points are (3,0) and (0,-4)
y₂=-4, y₁=0, x₁=3, x₂=0

The single inequality y > |x + 2| is equivalent to which of the following systems?
Answers:
1.y > x + 2
y > –x + 2
2.y > x + 2
y > –x – 2
3.y > x + 2
y < –x + 2
4.y > x + 2
y < –x – 2
The single inequality y > |x + 2| is equivalent to:
4. y > x + 2
y < –x – 2
What is an inequality?It should be noted that an inequality is simply used to show the relationship between the expressions that aren't equal.
The non-negative value of a real number x, regardless of its sign, is its absolute value or modulus | x |. For instance, 5 has an absolute value of 5, and 5 has a value of 5. One way to think about a number's absolute value is as its distance from zero on the real number line.
It should be noted that based on the information, the inequality is:
y > |x + 2|. This is the positive part of the modulus.
This is the same as y < –x – 2 when the signs are changed. This is the negative part of the modulus.
In conclusion, the correct option is 4.

The population of City A is 8.59 x 10^4. The population of City B is 3.2 x 10^3 Select all of the values that show the difference in population of City A and City B
The difference of population in these two cities are 85900- 3200
= 82,700
How do you calculate difference?
Subtract the largest number from the lowest number to determine the difference between two integers. The difference between the two numbers is the product of this sum. As a result, there are 55 between the numbers 45 and 100.
Given: Population of city A= 8.59 x 10^4
and population of city B = 3.2 x 10^3
This can also be written as :
Population of city A= 85,900
and population of city B = 3200

A) From the given graph, we see that the y-axis represents the probability of winning for each rank while the x-axis represents the ranks of the schools. Thus;
Slope unit = Probability of winning/Rank
B) The y-intercept is the point at which the graph crosses the y-axis. In this case, it means no ranked school and that is the probability of winning for an unranked school.
C) The linear equation is given by the formula;
y = -6.4x + 103.8

She has saved $7. How much money does she still need if 6% sales tax will be added to the cost of the CD.
Using the sales tax, the amount of money she still needs is $5.72
What is sales tax?A sales tax is a consumption tax imposed by the government on the sale of goods and services.
Jane wants to buy a CD for $12. She has saved $7.
The amount she needs if 6% sales tax is added to the cost can be calculated as follows;
Let's find the sales tax,
sales tax = 6% of 12
sales tax = 6 / 100 × 12
sales tax = 72 / 100
sales tax = $0.72
Therefore,
amount she needs to save = 12 + 0.72 - 7
amount she needs to save = 12.72 - 7

y = 3x + 5
y = 4x² + x
The system of equations has two solutions, these are:
(-0.89, 2.33) and (1.4, 9.2)
How to solve the system of equations?Here we have the following system of equations:
y = 3x + 5
y = 4x² + x
We can see that y is already isolated in both equations, so we can write the equation:
3x + 5 = y = 4x² + x
3x + 5 = 4x² + x
now we can solve this for x, this is just a quadratic equation:
3x + 5 - 4x² - x = 0
-4x² + 2x + 5 = 0
Using the quadratic formula, we can see that the two solutions are:
[tex]x = \frac{-2 \pm \sqrt{2^2 - 4*(-4)*5} }{2*-4} \\\\x = \frac{-2 \pm 9.17}{-8}[/tex]
So the solutions are:
x = (-2 +9.17)/-8 = -0.89
x = (-2 - 9.17)/-8 = 1.4
Evaluating the linear equation in these values, we get:
y = 3*(-0.89) +5 = 2.33
y = 3*(1.4) + 5 = 9.2
So the solutions of the system are:
(-0.89, 2.33) and (1.4, 9.2)

For the rectangle given, considering its diagonal properties, the value of x=4, while the angle VUR=36°
Angles and properties of plane shapesTo answer this question, let us recall the following:
The diagonals of a rectangle bisects each other into four eqaul length.The base angles of an Isosceles triangle are equal.Complementary angles add up to give a total of 90°.Hence;
the lengths RV and SV are
so, 3x+8=6x-4
6x-3x=8+4 [collecting like terms]
3x=12
when we divide both sides of the equation by 3, we have the value of x=4.
the angles VRS and VRU are complementary
so, 54°+VRU = 90°
VRU = 90°-54°
VRU = 36°
The triangle RUV is an Isosceles
so, angles VRU and VUR are equal, therefore angle VUR = 36°.
We can reduce from our workings that the value of x = 4 and the angle VUR is 36°.
