Answer:
4x^2 -16
Step-by-step explanation:
As with any "what must be added" problem, you subtract the parts you have from the result you want:
(3x^2 +4x +8) + (2x^2 -6x +3) + what = 9x^2 -2x -5
Identify the stuff on the left that is not "what" and subtract it from the equation:
what = (9x^2 -2x -5) - (3x^2 +4x +8) - (2x^2 -6x +3)
what = x^2(9 -3 -2) +x(-2 -4 +6) +(-5 -8 -3)
what = 4x^2 -16 . . . . . . . must be added to give the desired sum

What’s the probability of getting 3 hearts out of a deck of 52?
Answer:
Probability breaks down to this basic formula:
desired outcome
total possible outcomes
Also, you need to know there are 13 spades in a deck of cards.
So, on your first draw, the chances of getting a spade are:
13 (desired outcome: pick one of the 13 spades)
52 (total possibilities: 52 cards in the deck)
But on your second draw, if you don't replace the card, your chances of getting a spade are:
12
51
because you only have 12 spades left, and 51 cards total.
Then, on your last draw, the chances of getting a spade are down to:
11
50
Since each of these probabilities depend on each other, you multiply them up to get your overall probability:
13 * 12 * 11 = 1,716
52 51 50 132,600
This reduces, or you can just divide to get a decimal.

Find the measure of angle z in the following figure,
Answer:
B
Step-by-step explanation:
so you know that where it around angle c you use supplementry angels. this makes it 180-130=50.
you then know that the triangle is 90degrees plus 50 degrees plus x =180
90+50+z=180
140+z=180
z=40
Answer:
B) ∠z = 40°
Step-by-step explanation:
All three angles of a triangle add up to 180°. In this image, you can see that the angle ∠ACD is 130°. Because ∠ACB and ∠ACD are supplementary angles it means that their angles equal 180° when added together.
If ∠ADC = 130° then:
180° - 130° = 50°
Since we now know that ∠ACB is 50°, we can subtract our two angles from 180° to get the measurement for angle z.
180° - 50° - 90° =
180° - 140° = 40°

Equation:
A) $2,356.00
B) $937.00
C) $49,943.00
D) $21.00
Answer:
A) $2356.00
Step-by-step explanation:
Principal, p = $1,500.00
Interest rate, r= 6.5%
Period, t = 7 years
compounded quarterly therefore, n = 4
Amount, A = P( 1 + r/n)^ n*t
A = 1500 ( 1 + 0.065/4)^ 4*7
A = 1500( 1 + 0.016)^28
A = 1500 ( 1.016) ^28
A = 1500 * 1.57
A = $2356.00

A car dealership sells a car in a basic model (b) the fully-loaded model (f) for $20,000 and $25,000 respectively. During the month of June, the dealership sells 40 of these cars with sales totaling $880,000. How many of each model does the dealership sell?
A) 10 fully loaded and 20 basic
B) 16 fully loaded and 24 basic
C) 26 fully loaded and 9 basic
D) 30 fully loaded and 12 basic
Answer:
b
Step-by-step explanation:
The car dealership sold 24 basic model cars and 16 fully-loaded model cars. This was determined by creating and solving a set of linear equations based on the given information.
Explanation:This question can be approached using the method of linear equations. We know that the total number of cars sold is 40 and the total sales is $880,000. We can represent the number of basic model cars as 'b' and the fully-loaded model cars as 'f'. The cost of a basic model car is $20,000 and for a fully-loaded model, it is $25,000. Therefore, we can establish two equations:
b + f = 40 (number of cars sold) 20000b + 25000f = 880000 (total cost)
The system of these linear equations could be solved either by Substitution or Elimination method. Through careful calculation, it can be found that the answer is b=24 (basic models) and f=16 (fully-loaded models).
So, the correct answer is Option B : The dealership sold 16 fully loaded models and 24 basic models.

On Monday 3/12 of the students went on a field trip. What fraction of the students did not go on the field trip?
3/4 of the students did not go on the field trip.
On Monday, 3/12 of the students went on a field trip.
To find out what fraction of the students did not go on the field trip, we need to subtract the fraction that went on the field trip from the whole student body, which is represented by the fraction 1 or 12/12.
Let's perform the subtraction step-by-step:
Convert 1 to a fraction with the same denominator as 3/12: 1 = 12/12Subtract 3/12 from 12/12: 12/12 - 3/12 = 9/12Simplify the fraction 9/12: 9/12 = 3/4Therefore, 3/4 of the students did not go on the field trip.

eleven times the quotient of a number and 3 minus 15
The number is [tex]\( \frac{45}{8} \).[/tex]
Let's denote the unknown number as x. The given expression can be translated into an equation:
[tex]\[ 11 \times \left(\frac{x}{3}\right) - 15 \][/tex]
To find the number, set up the equation and solve for x:
[tex]\[ 11 \times \left(\frac{x}{3}\right) - 15 = x \][/tex]
First, distribute the 11:
[tex]\[ \frac{11x}{3} - 15 = x \][/tex]
Next, move [tex]\( \frac{11x}{3} \)[/tex] to the other side of the equation by subtracting it from both sides:
[tex]\[ -15 = x - \frac{11x}{3} \][/tex]
To combine the terms on the right side, find a common denominator (3):
[tex]\[ -15 = \frac{3x}{3} - \frac{11x}{3} \][/tex]
[tex]\[ -15 = \frac{-8x}{3} \][/tex]
Now, solve for x:
[tex]\[ x = \frac{-15 \times 3}{-8} \][/tex]
[tex]\[ x = \frac{45}{8} \][/tex]
So, the number is [tex]\( \frac{45}{8} \).[/tex]

Write the ratios of erasers to cost (dropping the dollar sign) as fractions:
(number of erasers)/(price): 2/1 and 10/4
The question is if the ratios 2/1 and 10/4 are equivalent.
2/1 = 2
10/4 = 2.5
A proportion is setting two ratios equal. Here, one ratio equals 2, and one ratio equals 2.5.
Since the ratios are not equivalent, the relation is not proportional.

[tex] = 6400 {m}^{2} [/tex]
The area of the figure is therefore
[tex] = 6400 + 3600[/tex]
[tex] = 10000 {m}^{2} [/tex]
Which BEST approximates the area of the geometric figure?
A 4 square units
B 7 square units
C 9 square units
D 11 square units
By decomposing the figure in simpler ones, we conclude that its area is 9 square units.
How to get the area of the figure?
Let's read the figure from the top.
First, we can see in the top two triangles that have an area of half a square unit, then adding these two we have one square unit.
Below that, there are 4 square units inside the figure.
On the left and right sides, there are triangles of base of 1 unit and height of 2 units, then each of these triangles has an area of:
a = 1*2/2 = 1 square unit
And we have 2 of these triangles, so the total area is 2 square units.
Finally, on the bottom we can see 4 triangles like in the top part, we know that each one of these measure 0.5 square units, then the 4 add up to 2 square units.
Adding all the areas above, we see that the total area is:
A = (1 + 4 + 2 + 2) square units = 9 square units.
So the correct option is C

Answer: 47.5 ft^2
Step-by-step explanation: First find the area of the rectangle using the formula length*height. This is 10*4 or 40.
Then find the area of the bottom triangle using the formula (base*height)/2. This will be (3*3)/2, which simplifies to 9/2, which is 4.5.
Then find the area of the top triangle using the same formula, which will be (2*3)/2, which simplifies to 6/2, which is 3.
Add all of these together. 40+3+4.5=47.5.
