An electronics shop offers a small ic chip for $1.50 per unit and $4.00 for large ic chip. on a certain day, 2200 chips were sold and $5050 is collected. how many small ic chips and how many large ic chips were sold?
Answers
.. s + l = 2200
.. 1.50s +4.00l = 5050
Solving these by your favorite method gives
.. s = 1500
.. l = 700
1500 small ICs and 700 large ICs were sold.
To determine the number of small and large IC chips sold, we set up a system of linear equations with the given total number of chips (2200) and total earnings ($5050). Solving the system, we found that 1500 small IC chips and 700 large IC chips were sold.
To solve the problem, we can set up a system of linear equations to represent the sales for small and large IC chips. We have two unknowns: the number of small IC chips (let's call it x) and the number of large IC chips (let's call it y). We have two pieces of information to create our equations:
The total number of chips sold is 2200, so x + y = 2200.
The total amount collected is $5050, so 1.50x + 4.00y = 5050.
Solving this system of equations, we multiply the first equation by 1.50 to align it with the second equation:
1.50x + 1.50y = 3300 (Multiply the first equation)
1.50x + 4.00y = 5050 (Second equation)
Subtracting the first new equation from the second gives us:
2.50y = 1750
Dividing both sides by 2.50 to find y gives us y = 700. That means 700 large IC chips were sold. Now, we can substitute y in the first equation to find x:
x + 700 = 2200
x = 2200 - 700
x = 1500
Hence, 1500 small IC chips and 700 large IC chips were sold.

The chemical formula for lithium phosphide is Li3P. Which best describes this ionic compound?
Answers
When lithium and phosphorus combine to form lithium phosphide, three lithium cations (Li+) combine with one phosphide anion (P₃-) to balance the charges and form a neutral compound, Li₃P.
What is Ionic compound?an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding.
The correct description of the ionic compound lithium phosphide, with the chemical formula Li3P, is "Lithium ions have 1 positive charge, and phosphorus ions have 3 negative charges."
This is because lithium is a Group 1A element, which means it has one valence electron that it tends to lose in chemical reactions to form a cation with a charge of +1.
Phosphorus, on the other hand, is a Group 5A element, which means it has five valence electrons and tends to gain three electrons to form an anion with a charge of -3.
Thus, When lithium and phosphorus combine to form lithium phosphide, three lithium cations (Li+) combine with one phosphide anion (P₃-) to balance the charges and form a neutral compound, Li₃P.

Amanda has a piece of ribbon that is 1/4 yard long. She wants to share ribbon with two friends so they can wear a ribbon for breast cancer awareness month. If each of the 3 friends get the same amount, how much ribbon will each person get?
Answers
Final answer:
To share the ribbon equally among the 3 friends, each person will get 1/12 yard of ribbon.
Explanation:
To determine how much ribbon each person will get, we need to divide the total length of the ribbon equally among all friends.
1/4 yard of ribbon divided by 3 friends gives each person 1/12 yard of ribbon.
Therefore, each person will get 1/12 yard of ribbon for breast cancer awareness month.

Which is the measure of the reference angle for 227 degrees
Answers
hope this helps<3
Algebraically, the reference angle for X is the smaller of (X mod 180°) and (-X mod 180°).
Here, that would be
.. min(227 mod 180, -227 mod 180)
.. = min(47, 133)
.. = 47 . . . . degrees
_____
"X mod 180" means you subtract the largest multiple of 180 that is smaller than X.
Then 227 mod 180 = 227 -180 = 47
and -227 mod 180 = -227 -(-360) = 133.

Which of the following functions is graphed below?!?
Answers
The given graph is for a piecewise function consisting of two intervals:
(1) x ≤ 1 ⇒⇒⇒ the graph in this interval like a cubic function.
(2) x > 1 ⇒⇒⇒ the graph in this interval like a quadratic function
By comparing to the given options
The answer is option c.
Answer:
Option C is correct.
Explanation:
A piece-wise function is a function which is defined by multiple sub-functions, each sub-function applying to a certain interval of the main function's domain.
From the graph we can see that the function is made up of 2 pieces.
Solid dot means- Including
Open-dot means - not- including.
As we can see that the boundary lines are at x=1.
We have to look each line separately to determine each equation:
when [tex]x>1[/tex], it gives the function [tex]y=x^2+4[/tex] and
when [tex]x\leq 1[/tex], it gives the function [tex]y =x^3-2[/tex].
So, the piece-wise function is:
[tex]y=\left \{ {{x^3-2}, x\leq1 \atop {x^2+4}, x>1} \right.[/tex]

The angle bisector of ∠ACD in rhombus ABCD makes a 64° angle with the diagonal BD . Find the measure of ∠BAD.
Answers
In a rhombus, the diagonals are perpendicular bisectors of each other, meaning they divide each other into two equal parts at a right angle. Let's denote the measure of ∠BAD as x degrees. The measure of ∠BAD is [tex]\( 26^\circ \)[/tex].
Since the angle bisector of ∠ACD makes a 64° angle with the diagonal BD, and BD bisects ∠ACD, then ∠ACB = 64° as well. Additionally, since ABCD is a rhombus, opposite angles are equal. Therefore, ∠ABD = ∠ACB = 64°.
Now, considering triangle ABD, we know that the sum of angles in a triangle is 180°. Thus:
[tex]\[ \angle BAD + \angle ABD + \angle ADB = 180^\circ \][/tex]
Substituting the known values:
[tex]\[ x + 64^\circ + 90^\circ = 180^\circ \][/tex]
[tex]\[ x + 154^\circ = 180^\circ \][/tex]
[tex]\[ x = 180^\circ - 154^\circ \][/tex]
[tex]\[ x = 26^\circ \][/tex]
So, the measure of ∠BAD is [tex]\( 26^\circ \)[/tex].
To summarize:
1. The angle bisector of ∠ACD in the rhombus makes a 64° angle with diagonal BD.
2. By the properties of a rhombus, ∠ACB = 64° as well.
3. Since opposite angles in a rhombus are equal, ∠ABD = ∠ACB = 64°.
4. In triangle ABD, the sum of angles is 180°.
5. Solving for ∠BAD, we find [tex]\( 26^\circ \).[/tex]

The coordinates (5, 2) and (–6, 2) are vertices of a hexagon. Explain how to find the length of the segment formed by these endpoints. How long is the segment?
Answers
Point 1 ----------> (5, 2)
Point 2 ----------> (–6, 2)
we know that
the distance between two points it is calculated with the formula
d=√[(y2-y1)²+(x2-x1)²]
then
d=√[(2-2)²+(-6-5)²]
d=√[(0)²+(-11)²]
d=√[121]
d=√121-----------> d=11 units
the answer is 11 units
The length of the segment formed by the two given endpoints with coordinates coordinates (5, 2) and (–6, 2) is;
d = 11
Formula for distance between two coordinates is given as;
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
We are given the coordinates (5, 2) and (–6, 2).
This means that;
x₁ = 5 and x₂ = -6
y₁ = 2 and y₂ = 2
Thus;
d = √[(-6 - 5)² + (2 - 2)²]
d = √(121 + 0)
d = √121
d = 11
In conclusion, the length of the segment formed by the two given endpoints is; d = 11
