Find the value of two numbers if their sum is 13 and their difference is 3
Answers
Consider the two numbers as
x and y
. From the given data, we write:
x−y=3
x+y=13
From the first equation, we determine a value for x.
x−y=3
Add y to both sides.
x=y+3
In the second equation, substitute x with (y+3).
x+y=13
(y+3)+y=13
Open the brackets and simplify.
y+3+y=13
2y+3=13
Subtract 3 from each side.
2y=10
Divide both sides by 2.
y=5
In the first equation, substitute y with 5.
x−y=3
x−5=3
Add 5 to each side.
x=8

Suppose you built a catapult that can launch a ball
from the ground at an initial velocity of 16 feet per
second. The function h(t) = -16t2 + 16t represents the
height, h(t), in feet, that the ball has reached after t
seconds. What domain is reasonable for the
function? Explain.
Answers
Answer:
0 ≤ t ≤ 1
Step-by-step explanation:
The function can be factored as ...
h(t) = -16t(t -1)
It will have non-negative values for t in the interval [0, 1]. Negative values of h don't make much sense in this context, so the reasonable domain is [0, 1].
What is the area of this polygon
Answers
Answer:
45 units²
Step-by-step explanation:
The polygon is composed of a rectangle FSCW and Δ FSN
area of rectangle = WC × WF = 9 × 2 = 18 units²
area of triangle = 0.5 × FS × perpendicular height from vertex N
A = 0.5 × 9 × 6 = 27 units²
Area of polygon = 18 + 27 = 45 units²
The area of a polygon is calculated using geometric formulas based on the shape and dimensions of the polygon.
Regular polygons and composite shapes require specific formulas, while irregular polygons might need more advanced techniques.
Explanation:To determine the area of a polygon, we use the concept that the area is a measure of the two-dimensional space inside the boundary of a polygon.
A polygon is made of line segments that connect in a closed chain.
Given the description and assuming the polygon is regular or can be divided into recognizable shapes such as triangles, rectangles, or circles, we can use various geometric formulas to calculate the area.
For example, if the polygon is a rectangle, the area is the product of its length and width.
If the polygon can be divided into a series of triangles, we can calculate the area of each and sum them up.
In more complex scenarios, such as irregular polygons, we might need to use methods like triangulation or calculus, depending on the information provided.
solving systems of linear equations by graphing 2x+3y=-12 and 10x+3y=12
Answers
Answer:
(x, y) = (3, -6)
Step-by-step explanation:
I like a good graphing calculator for solving systems of equations by graphing.
__
If you're solving these by hand, you need to graph the equations. It can be convenient to put the equations into "intercept form" so you can use the x- and y-intercepts to draw your graph.
That form is ...
x/(x-intercept) +y/(y-intercept) = 1
Dividing a standard-form equation by the constant on the right will put it in this form.
x/(-12/2) +y/(-12/3) = 1 . . . . . . divide the first equation by -12
x/(-6) +y/(-4) = 1 . . . . . . . . . . . the x-intercept is -6; the y-intercept is -4
__
x/(12/10) +y/(12/3) = 1 . . . . . . divide the second equation by 12
x/1.2 +y/4 = 1 . . . . . . . . . . . . . the x-intercept is 1.2*; the y-intercept is 4
__
The locations of these intercepts and the slopes of the lines tell you that the solution will be in the fourth quadrant. The lines intersect at (x, y) = (3, -6).
_____
* It can be difficult to draw an accurate graph using an intercept point that is not on a grid line. It may be desirable to put the second equation into slope-intercept form, so you can see the rise/run values that let you choose grid points on the line. That equation is y =-10/3x +4. A "rise" of -10 for a "run" of +3 will get you to (3, -6) starting from the y-intercept of (0, 4).

After kicking, one coach likes to play practice games with 6 players on each
team. She doesn’t like any team to have more or fewer than 6 players and
she doesn’t like anyone to be left off a team. What are the possible numbers
of players who must show up to practice so that the coach can make these
teams?
Answers
Final answer:
The possible numbers of players who must show up to practice so that the coach can make teams with 6 players on each team are any number that is divisible by 6.
Explanation:
In order for the coach to make teams with 6 players on each team, the total number of players must be a multiple of 6. This means that the possible numbers of players who must show up to practice are any number that is divisible by 6.
For example, if there are 6 players, they can all be on one team. If there are 12 players, they can be divided into two teams of 6 players each. If there are 18 players, they can be divided into three teams of 6 players each, and so on.
So, the possible numbers of players who must show up to practice are:
6, 12, 18, 24, 30, 36...

A company produces three combinations of mixed vegetables that sell in 1-kg packages. Italian style combines 0.4 kg of zucchini, 0.3 kg of broccoli, and 0.3 kg of carrots. French style combines 0.5 kg of broccoli and 0.5 kg of carrots. Oriental style combines 0.2 kg of zucchini, 0.3 kg of broccoli, and 0.5 kg of carrots. The company has a stock of 17 comma 800 kg of zucchini, 28 comma 300 kg of broccoli, and 38 comma 900 kg of carrots. How many packages of each style should it prepare to use up existing supplies?
Answers
Answer:
Italian style = 18,000 packages
French style = 14,000 packages
Oriental style = 53,000 packages
Step-by-step explanation:
See the attached figure to represent the question
let the number of packages of Italian style = x
let the number of packages of French style = y
let the number of packages of Oriental style = z
By using the figure we can make the following equations:
0.4x + 0 * y + 0.2z = 17,800
0.3x + 0.5y + 0.3z = 28,300
0.3x + 0.5y + 0.5z = 38,900
Solving the 3 equations together to find x , y and z
Using the calculator:
x = 18,000 ⇒ Italian style packages
y = 14,000 ⇒ French style packages
z = 53,000 ⇒ Oriental style packages

If 70% of children who like green are boys,how many boys like green?
Answers
Answer:
How many boys are there in total? We can't answer correctly until you give us all the information.
Step-by-step explanation:
The percentage of students who like both oranges and apples (x%) is equal to or greater than 34%.
Let's start by representing the students who like oranges as set A and the students who like apples as set B. We are interested in finding the percentage of students who like both oranges and apples, which corresponds to the intersection of sets A and B.
Based on the given information:
Percentage of students who like oranges (A): 70%
Percentage of students who like apples (B): 64%
Percentage of students who like both oranges and apples (x%): ?
Now, let's use set theory notation to represent the information:
A = students who like oranges
B = students who like apples
A ∩ B = students who like both oranges and apples
The total percentage of students who like oranges or apples can be calculated using the principle of inclusion-exclusion:
Percentage(A ∪ B) = Percentage(A) + Percentage(B) - Percentage(A ∩ B)
We know that Percentage(A) = 70% and Percentage(B) = 64%. Let's denote Percentage(A ∪ B) as y% for simplicity.
y% = 70% + 64% - x%
y% = 134% - x%
Since the total percentage cannot exceed 100% (as it represents the whole student population), we can conclude that:
y% ≤ 100%
134% - x% ≤ 100%
x% ≥ 34%
So, the Main Answer is x% ≥ 34%

A laptop computer uses 78.0 W of power. If it runs for 10.0 minutes, how much energy does it use? (Answer will be in Joules)
Answers
time must be in seconds
10mins = 600 seconds
energy=78.0 x 600
energy= 46,800 Joules
Final answer:
To calculate the energy used by a laptop in Joules, multiply its power usage in watts (78.0 W) by the time it was running in seconds (10.0 minutes converted to 600 seconds). The laptop uses 46,800 Joules of energy.
Explanation:
The question asks for the amount of energy used by a laptop computer that has a power rating of 78.0 W when it runs for 10.0 minutes. To find the energy in Joules, we use the equation for energy, which is E = P * t, where E is energy in Joules, P is power in watts, and t is time in seconds.
First, we convert the time from minutes to seconds: 10.0 minutes * 60 seconds/minute = 600 seconds. Then we plug the values into the equation:
E = 78.0 W * 600s = 46,800 J
Therefore, the laptop uses 46,800 Joules of energy.

Find the perimeter of this semi-circle with diameter,
d
= 34cm.
Give your answer as an expression in terms of
π
.
Answers
Answer:
The answer to your question is P = 17(π + 2) or 17π + 34
Step-by-step explanation:
Data
Diameter = 34 cm
Formula
P = rπ + 2r
Process
1.- Find the radius
radius = diameter / 2
radius = 34 / 2
radius = 17 cm
2.- Substitute the values in the formula
P = 17π + 2(17)
3.- Simplification
P = 17π + 34
4.- Factor
P = 17(π + 2)
The perimeter of the semi-circle with a diameter of 34 cm is 51π cm.
Explanation:The perimeter of a semi-circle can be found by adding the length of the straight edge (which is equal to half the circumference of a full circle) to the diameter. In this case, the diameter is 34 cm.
The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter. Since we only have half of the circle, we divide the circumference by 2 to get the perimeter of the semi-circle.
Therefore, the perimeter of the semi-circle is (πd/2) + d = (π * 34 cm / 2) + 34 cm = 17π cm + 34 cm = 51π cm.

$1000 + $ 1000 = $ 2000
Answer: a combination of 75 adult tickets and 250 student tickets would make $2000
Step-by-step explanation:
A theater wants 2000$ and children’s tickets cost 5$ and adult tickets cost 10$. To find a combination of children and adult tickets that will make 2000$, we would assume a value for either the number of student tickets or adult tickets and assume a variable for the other.
Assuming 250 student tickets and x adult tickets were sold. Therefore,
250 × 5 + 10x = 2000
1250 + 10x = 2000
10x = 2000 - 1250 = 750
x = 750/10 = 75

Malia has 6 groups of 18 buttons. How many buttons does Malia have altogether?
Answers
6 groups of 18 buttons would translate into multiplication.
6 x 18 = 108 buttons total that Malia has.
Final answer:
To determine the total number of buttons Malia has, multiply the number of groups (6) by the number of buttons per group (18), resulting in 108 buttons altogether.
Explanation:
The question concerns a basic arithmetic operation of multiplying two numbers together to find the total quantity of items. Malia has 6 groups of 18 buttons each.
To find out how many buttons she has altogether, we need to perform a multiplication of the two numbers. Multiplying the number of groups by the number of buttons in each group gives us:
Multiply the number of groups (6) by the number of buttons per group (18).
6 groups × 18 buttons per group = 108 buttons.
Therefore, Malia has 108 buttons altogether.
