Grace has a segment with endpoints C (3, 4) and D (11, 3) that is divided by a point E such that CE and DE form a 3:5 ratio. She knows the distance between the x coordinates is 8 units. Which of the following fractions will let her find the x coordinate for point E?
The value of x coordinate for point E is,
⇒ x = 6
What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
Grace has a segment with endpoints C (3, 4) and D (11, 3)
And, It is divided by a point E such that CE and DE form a 3:5 ratio.
Hence, We get;
The coordinates of E is,
E = [ ( 3× 11 + 5 × 3)/(3 + 5) , (3×3 + 5 × 4)/(3 + 5) ]
= [ (33 + 15)/8 , (9 + 20)/8 ]
= *(48/8 , 29/8)
= (6 , 3.625)
Thus, The value of x coordinate for point E is,
⇒ x = 6

Answer:
x = 1 ± [tex]\sqrt{5}[/tex]
Step-by-step explanation:
x(x - 2) = 4
Multiply x on the left side by foil.
[tex]x^{2}- 2x = 4[/tex]
Subtract 4 on both sides.
[tex]x^{2} -2x-4=0[/tex]
Now, the quadratic formula.
x = (-b ± [tex]\sqrt{b^{2} - 4ac }[/tex]) / 2a
Using the standard form equation.
Ax² + Bx + C = 0
(1)x² - 2x - 4 = 0
A = 1
B = -2
C = -4
x = (-(-2) ± [tex]\sqrt{(-2)^{2}-4(1)(-4) }[/tex]) / 2(1)
x = (2 ±[tex]\sqrt{4+16}[/tex] ) / 2
x = (2±[tex]\sqrt{20}[/tex])/2
x = (2±2[tex]\sqrt{5}[/tex])/2
x = 1 ± [tex]\sqrt{5}[/tex]

Answer:
#1
Well lets solve the polynomial first.
(4p +3) ^2
That is basically
(4p + 3) (4p + 3)
And we’re trying to find the error in the “equal” solution.
16p^2 + 8p + 9.
So let’s solve the polynomial first
Following F.O.I.L
F- First
O- Outter
I- Inner
L- Last
So doing the equation in order.
4p * 4p = 16p^2
4p * 3 = 12p
3 * 4p = 12p
3* 3 = 9
Added it all up.
16p^2 + 12p + 12p + 9
Simplify.
16p^2 +24p +9
We can see that in this case the 8p is wrong.
So we replace 8p with 24p
In this case the last option.
Factoring #2
So we’re factoring
9x^2 -6x - 3
So how are we gonna do this.
So I’m just gonna go over the simple method.
The standard form of a quadratic is
Ax^2 + bx + c = 0
We don’t have to worry about the equal 0 part here for now.
ax^2 + bx + c
A being the number next to x^2
B is the number being next to x
C is the number that is next to nothing, jsut a plain whole number (sometimes whole number)
So let’s plug it in.
(It’s already plugged in so we can solve)
9x^2 - 6x - 3
Multiply a and c in ths case being, 9 and -3.
You’d get -27
We need two numbers that multiply to -27 and add up to -6
From here it’s guessing and checking.
Here’s my process.
trial 1
Since the sum is negative, it has to be negative + negative or positive + negative greater then the positive. Or vice versa but positive is less then negative.
But the product has to be -27,negative * negtaive is positive, so it has to be positive * negative and positive + negative.
I look at -27 and think of two numbers that would give the lowest.
-9 * 3
-9 * 3 = -27
-9 + 3 = -6
It looks like I got it already on the first try.
The numbers are -9 and 3
end of trial 1
So now I know that the numbers are -9 and 3.
Using that information I just plug it into the quadratic but replace it with b.
9x^2 -9x + 3x - 3
Now you can simplify this
In the end you’d get
3 (3x+1)(x-1)
You’d have the third option open to you
Figure out the second one using these strategies

Selling prices, variable costs, and sales percentages of each type of cooler: Model X100: selling price – 8,800; variable cost – 7,600; sales mix – 30% Model X950: selling price – 14,800; variable cost – 12,000; sales mix – 50% Model X800: selling price – 24,000; variable cost – 20,000; sales mix – 20% Compute the: A) break-even point in units B) break-even point in pesos C) if the company has a target profit of 1M, compute the number of units of each type of cooler that must be sold
A) The computation of the break-even point in units for Green Meadows, which makes three types of portable coolers, can be determined using the following break-even formula:
= Fixed costs/Weighted contribution margin per unit
Model X100 Model X950 Model X800
= 3,000 units 771 units 1,350 units
(1,080,000/$360) (1,080,000/1,400) (1,080,000/800)
B) The computation of the break-even point in pesos for Green Meadows, which makes three types of portable coolers, can be determined using the following break-even formula:
= Fixed costs/Weighted contribution margin per unit
Model X100 Model X950 Model X800
= 240 million pesos 11,416,490 pesos 32,432,432 pesos
(1,080,000/0.45%) (1,080,000/9.46%) (1,080,000/3.33%)
C) If Green Meadows has a target profit of 1M, the number of units of each type of cooler that must be sold is determined using the following break-even formula:
= Fixed costs + Target Profit /Weighted contribution margin per unit
Model X100 Model X950 Model X800
= 5,778 units 1,486 units 2,600 units
(2,080,000/$360) (2,080,000/1,400) (2,080,000/800)
What is break-even analysis?The break-even analysis is an accounting technique used to determine the break-even point.
The break-even point shows the units or dollars that must be achieved so that the total revenue equals the total costs, both variable and fixed.
Data and Calculations:Fixed cost = 1,080,000 pesos

a) In how many ways can the volunteers be assigned? [2]
b) Mary and Martha are new volunteers this year, so they should not be placed together. In how many ways can the volunteers be assigned so that Mary and Martha are not at the same station? [3]
The combination and permutations computed shows that the number of ways that the volunteers can be assigned is 120120.
How to calculate the combinationFrom the information given, the number of ways that the volunteers can be assigned will be:
= 14C3 × 11C4 × 7C7.
= (14 × 13 × 12)/6 × (11 × 10 × 9 × 8)/24
= 120120
Also, the number of ways that the volunteers can be assigned so that Mary and Martha are not at the same station will be:
= 12C1 × 11C4 × 7C7
= 12 × 330 × 1

At a basketball game, a vender sold a combined total of 172 sodas and hot dogs. The number of hot dogs sold was 46 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold.
Answer:
Let x = # of hot dogs sold
Let x + 31 = # of sodas sold
For the total, do: x + x + 31 = 173
2x + 31 = 173
-31 -31
2x = 142
Divide out both sides by 2; to get: x - 71
That gives us 71 hot dogs; and 71 + 31 = 102 sodas
To test this: 71 + 71 + 31 = 173
173 = 173 [Check]

Identical lines through the sides of a triangle indicate that the sides are congruent.
What is the congruent triangle?Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.
Congruent triangles are two triangles that are identical in terms of size and shape. One of two congruent triangles remains congruent even if it is rotated, flipped, or turned. Two triangles must have the same sides in order for them to have the same angles and, as a result, to be congruent.
Thus, identical lines through the sides of a triangle indicate that the sides are congruent.
