Mr. Hernandez combines 1 gallon of orange juice, 3 pints of pineapple juice, and 2 quarts of lemon‐lime soda to make punch for a party. He allows 2 cups of punch for each guest. Will there be enough punch to serve all 14 guests? How much, if any, punch will be left?
Answer:
In total there are 30 cups and there are 2 left over
Step-by-step explanation:
The first thing is to clarify the equivalences, we have to:
1 gallon = 4 quarts
1 quart = 2 pints
1 pint = 2 cups
We will pass everything to cups,
1 gallon of orange juice = 16 cups
3 pints of pineapple juice = 6 cups
2 quarts of lemon ‐ lime soda = 8 cups
So in total they would be 16 + 6 + 8 = 30 cups
How to get 2 cups for 14 guests in total would be 28 cups, which means that if 2 cups are left and left over.

A man has $0.70 in dimes and nickels. He has 8 coins altogether. How many nickels does he have?
Answer:
Number of nickels: 2,
Number of dimes: 6
Step-by-step explanation:
Say d ⇒ number of dimes, n ⇒ number of nickels; from this we can formulate two equation knowing the cost per dime ⇒ $ 0.1, and the cost per nickel ⇒ $0.05
d + n = 8,
0.1 * d + 0.05 * n = 0.7 ⇒ Let us solve through substitution
d = 8 - n into 0.1 * d + 0.05 * n = 0.7,
0.1 * ( 8 - n ) + 0.05 * n = 0.7,
0.8 - 0.1 * n + 0.05 * n = 0.7,
0.8 - 0.1n + 0.05n = 0.7,
- 0.05n = - 0.1,
Number of nickels: 2 ⇒ Now let us substitute this value into the first equation as to solve for d, dimes
d = 8 - 2,
Number of dimes: 6

A ball is dropped from 16 feet above a hard surface. After each time it hits the surface, it rebounds to a
height that is 3/4 of its previous maximum height. What is the total vertical distance, to the nearest foot, the ball has traveled when it strikes the ground for the 10th time? Write out the first five terms of this sum to help visualize.
Answer:
a) Total distance travelled to the nearest foot = 105ft
b) First 5 terms = 12, 9, 6.75, 5.0625, 3.796875
Step-by-step explanation:
From the question above, we can see that this is a geometric series or progression
Formula for geometric progression:
Tn = arⁿ-¹
Where
a = first term
r = common ration
n = number of terms
From the question, we are told that the ball dropped from 16 feet
Hence First term(a) = 16
We are told that the ball rebounds to 3/4 of it's previous height anytime it hits the surface.
Hence, common ratio(r) = 3/4
a) We are told to find total distance to the nearest foot that the ball travelled when it strikes the ground for the 10th time
This means we are to find the sum of the first 10 terms.
Because the ball rises and falls, we would use the rises form
Where the first term = 12 and the number of times is 9 because it rises 9 times
The formula we would use to find this sum is based on if the common ratio is less than or greater than 1
Our common ratio = 3/4, hence it is less than 1.
When r< 1, sum of n terms =
Sn = a(1 - rⁿ)/ 1 - r
It is important to
Where a = 12
r = 3/4
n = 9
Sn = 12( 1 - (3/4)^9) / 1- 3/4
Sn = 104.79ft
Approximately = 105ft
b) First five terms
Using the formula
Tn = arⁿ-¹
Where
a = first term = 12
r = common ration
n = number of terms
First term, n = 1 = 12 × 3/4^(1-1)
= 12 × 3/4 ^(0)
= 12× 1
= 12
Second term, n = 2 = 12 × 3/4^(2-1)
= 12 × 3/4 ^(1)
= 36/4
= 9
Third term, n = 3 = 12 × 3/4^(3-1)
= 12 × (3/4)²
= 6.75
Fourth term, n = 4= 12 × 3/4^(4-1)
= 12 × (3/4)³
= 5.0625
Fifth term, n = 5 = 12 × 3/4^(5-1)
= 12 × (3/4)⁴
= 3.796875
Therefore, the first 5 terms = 12, 9, 6.75, 5.0625, 3.796875
The rebound of the ball from the height is an illustration of a geometric series
The total vertical distance at the 10th rebound is 60.352 feetThe first five terms of the sum are 16, 12, 9, 6.75 and 5.0625(a) The total vertical distance
The given parameters are:
[tex]\mathbf{a = 16}[/tex] -- the first term
[tex]\mathbf{r = \frac 34}[/tex] -- the common ratio
[tex]\mathbf{n = 10}[/tex] -- number of terms
The total vertical distance when it strikes for the 10th time is the sum of nth terms of the geometric series.
So, we have:
[tex]\mathbf{S_n = \frac{a(1 - r^n)}{1- r}}[/tex]
Substitute values for (a), (r) and n
[tex]\mathbf{S_{10} = \frac{16(1 - 3/4^{10)}}{1- 3/4}}[/tex]
Simplify
[tex]\mathbf{S_{10} = \frac{16(0.943)}{0.25}}[/tex]
[tex]\mathbf{S_{10} = 60.352}[/tex]
Hence, the total vertical distance at the 10th rebound is 60.352 feet
(b) The first five terms of this sum
The nth term of a geometric series is:
[tex]\mathbf{T_n = ar^{n-1}}[/tex]
So, we have:
[tex]\mathbf{T_1 = 16}[/tex]
[tex]\mathbf{T_2 = 16 * 3/4 = 12}[/tex]
[tex]\mathbf{T_3 = 12 * 3/4 = 9}[/tex]
[tex]\mathbf{T_4 = 9 * 3/4 = 6.75}[/tex]
[tex]\mathbf{T_5 = 6.75 * 3/4 = 5.0625}[/tex]
Hence, the first five terms of the sum are 16, 12, 9, 6.75 and 5.0625

factorise x square - 7 x minus 42
Answer:
x =(7-√217)/2=-3.865
x =(7+√217)/2=10.865 mark brainliest please
Step-by-step explanation:
Factoring x2-7x-42
The first term is, x2 its coefficient is 1 .
The middle term is, -7x its coefficient is -7 .
The last term, "the constant", is -42
Step-1 : Multiply the coefficient of the first term by the constant 1 • -42 = -42
Step-2 : Find two factors of -42 whose sum equals the coefficient of the middle term, which is -7 .
-42 + 1 = -41
-21 + 2 = -19
-14 + 3 = -11
-7 + 6 = -1
-6 + 7 = 1
-3 + 14 = 11
-2 + 21 = 19
-1 + 42 = 41
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Equation at the end of step 1 :
x2 - 7x - 42 = 0
Step 2 :
Parabola, Finding the Vertex :
2.1 Find the Vertex of y = x2-7x-42
Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero).
Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.
Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.
For any parabola,Ax2+Bx+C,the x -coordinate of the vertex is given by -B/(2A) . In our case the x coordinate is 3.5000
Plugging into the parabola formula 3.5000 for x we can calculate the y -coordinate :
y = 1.0 * 3.50 * 3.50 - 7.0 * 3.50 - 42.0
or y = -54.250
Parabola, Graphing Vertex and X-Intercepts :
Root plot for : y = x2-7x-42
Axis of Symmetry (dashed) {x}={ 3.50}
Vertex at {x,y} = { 3.50,-54.25}
x -Intercepts (Roots) :
Root 1 at {x,y} = {-3.87, 0.00}
Root 2 at {x,y} = {10.87, 0.00}
Solve Quadratic Equation by Completing The Square
2.2 Solving x2-7x-42 = 0 by Completing The Square .
Add 42 to both side of the equation :
x2-7x = 42
Now the clever bit: Take the coefficient of x , which is 7 , divide by two, giving 7/2 , and finally square it giving 49/4
Add 49/4 to both sides of the equation :
On the right hand side we have :
42 + 49/4 or, (42/1)+(49/4)
The common denominator of the two fractions is 4 Adding (168/4)+(49/4) gives 217/4
So adding to both sides we finally get :
x2-7x+(49/4) = 217/4
Adding 49/4 has completed the left hand side into a perfect square :
x2-7x+(49/4) =
(x-(7/2)) • (x-(7/2)) =
(x-(7/2))2
Things which are equal to the same thing are also equal to one another. Since
x2-7x+(49/4) = 217/4 and
x2-7x+(49/4) = (x-(7/2))2
then, according to the law of transitivity,
(x-(7/2))2 = 217/4
We'll refer to this Equation as Eq. #2.2.1
The Square Root Principle says that When two things are equal, their square roots are equal.
Note that the square root of
(x-(7/2))2 is
(x-(7/2))2/2 =
(x-(7/2))1 =
x-(7/2)
Now, applying the Square Root Principle to Eq. #2.2.1 we get:
x-(7/2) = √ 217/4
Add 7/2 to both sides to obtain:
x = 7/2 + √ 217/4
Since a square root has two values, one positive and the other negative
x2 - 7x - 42 = 0
has two solutions:
x = 7/2 + √ 217/4
or
x = 7/2 - √ 217/4
Note that √ 217/4 can be written as
√ 217 / √ 4 which is √ 217 / 2
Solve Quadratic Equation using the Quadratic Formula
2.3 Solving x2-7x-42 = 0 by the Quadratic Formula .
According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 1
B = -7
C = -42
Accordingly, B2 - 4AC =
49 - (-168) =
217
Applying the quadratic formula :
7 ± √ 217
x = —————
2
√ 217 , rounded to 4 decimal digits, is 14.7309
So now we are looking at:
x = ( 7 ± 14.731 ) / 2
Two real solutions:
x =(7+√217)/2=10.865
or:
x =(7-√217)/2=-3.865
Answer:
x^2 - 7x - 42
x^2 - x (21 - 14 ) - 42
x^2 - 21x + 14x -42
7x ( x - 3) + 14 ( x- 3)
(x -3) (7x + 14)
hope this helps you
