Answer:
(1-[tex]\sqrt{33}[/tex])/4 and (1+[tex]\sqrt{33}[/tex])/4
Step-by-step explanation:
-2x^2 + x + 4 = 0
use quadratic formula x= (-b±[tex]\sqrt{b^{2} -4ac}[/tex] ) / 2a
a=-2
b=1
c=4
x= (-1±[tex]\sqrt{1^{2} -4(-2)(4)}[/tex] ) / 2(-2)
x=(-1±[tex]\sqrt{33}[/tex] ) / -4
x=(1 -[tex]\sqrt{33}[/tex]) / 4 and (1 +[tex]\sqrt{33}[/tex]) / 4
Phil sold 11 small boxes and 10 large boxes of tangerines for a total of $146. Nick sold 5 small boxes of tangerines and 12 large boxes of tangerines for a total of $126.
Given :
Phil sold 11 small boxes and 10 large boxes of tangerines for a total of $146.
Nick sold 5 small boxes of tangerines and 12 large boxes of tangerines for a total of $126.
To Find :
The price of each small box and large box.
Solution :
Let, price of small box is x and large box is y.
Mathematical expression of given equations :
11x + 10y = 146 ...1)
5x + 12y = 126 ...2)
Solving above equation, we get :
x = 6 and y = 8
Therefore, price of small and large box is $6 and $8 respectively.
Hence, this is the required solution.

Nathan took his car in for service and repairs. He had a coupon for 10% off.
Original Prices
• Labor $254.58
• Parts $333.90
• Other $64.42
Which amount is closest to Nathan's total costs after the 10% discount and including 6% sales tax? [Assume tax is applied after the discount is applied.]
Answer:
$594.21
Step-by-step explanation:
Because 254.58 + 333.90+ 64.42= $622.87
and 10 off of $622.87 = $560.58
and 6% sales tax to $560.58 = $594.21

Graph a line that contains the point (3,-6) and has a slope of
2
khan academy i need it!!
Answer:
[tex]\boxed {\boxed {\sf y= 2x-12}}[/tex]
Step-by-step explanation:
We are given a slope and a point, so we can use the point-slope equation.
[tex]y-y_1=m(x-x_1)[/tex]
where m is the slope and (x₁, y₁) is the point.
The slope is 2 and the point is (3,-6).
[tex]m= 2\\x_1=3 \\y_1=-6[/tex]
Substitute the values into the formula.
[tex]y--6=2(x-3)[/tex]
[tex]y+6=2(x-3)[/tex]
Distribute the 2 on the right side of the equation.
[tex]y+6=(2*x)+(2*-3)[/tex]
[tex]y+6=2x-6[/tex]
We want to get the line into the form: y=mx+b. We have to isolate y on one side of the equation. 6 is being added to y. The inverse of addition is subtraction; subtract 6 from both sides of the equation.
[tex]y+6-6=2x-6-6[/tex]
[tex]y=2x-6-6[/tex]
[tex]y=2x-12[/tex]
The line is y=2x-12 (slope=2 and y-intercept=-12)

if a square has an area of 324 ft what is the length of each side
Answer:
162
Step-by-step explanation:
324/2 because a square has sides that are all equal, so the area is 2 times the length of a side
Answer:
18 ft.Step-by-step explanation:
area = L² where area = 324 ft²
324 = L²
L = √324
L = 18 ft.

Una jarra vacia pesa 0.64 kg, llena de agua 1.728 kg. ¿Cuánto pesa el agua?
Answer:
Pesa 1.088kg
Step-by-step explanation:
Peso jarra vacía --> 0.64kg
Peso jarra llena de agua --> 1.728kg
Peso agua = peso jarra vacía - peso jarra llena
Peso agua = 1.728kg - 0.64kg = 1.088kg
Peso agua= 1.088kg

Answer:
75 adult tickets125 child ticketsStep-by-step explanation:
Let 'a' represent the number of adult tickets sold. Then (200-a) is the number of child tickets sold, and the revenue is ...
8a +5(200 -a) = 1225
3a = 225 . . . . . . . . . . subtract 1000, simplify
a = 75 . . . . . . . . . . . . .divide by 3
200 -a = 125
75 adult ($8) and 125 child ($5) tickets were sold.

Rollin and Sandra want to buy a home priced at $265,000. They plan to finance this amount less the down payment
required. Rollin and Sandra have a combined annual income of $83,600 and have saved $53,000. They have a
recurring debt of $582. Use a 20% down payment and the 28/36 ratio to determine if Rollin and Sandra are eligible for
a loan. What would you advise them to do if they are not eligible?
Answer:
Rollin and Sandra will not be eligible for a loan. Since 20% of $265,000 is $53,000, they have the required down payment.The recurring debt they have exceeds the allowable amount of $557. Rollin and Sandra should work on reducing their recurring debt.
Step-by-step explanation: this is what i put on the practice
Based on the 28/36 rule, the Rollin and Sandra family are eligible for the mortgage loan of $212,000.
Data and Calculations:Price of home = $265,000
Required down payment = 20% or $53,000
Amount saved = $53,000
Combined annual income of Rollin and Sandra = $83,600
Recurring debt = $582 per month
Annual recurring debt = $6,984 ($582 x 12)
The Rollin and Sandra family will need to finance $212,000 ($265,000 - $53,000) of the home price.
At 6% interest rate for 30 years, the Rollin and Sandra household will pay $1,271.05 monthly or $15,252.60 yearly. This gives a total annual debt payment of $22,236.60 ($6,984 + $15,252.60).
Thus, based on the 28/36 rule, the Rollin and Sandra family are eligible for the mortgage loan of $212,000.

Tickets for the school play cost $7 each. Each member of the cast gets 1 free ticket for a family member. For the run of the play, 210 tickets are collected, including all the free tickets, and the box office makes $1,358 from ticket sales. The equation that models this situation is7(210 – c) = 1,358 where c is the number of cast members. How many cast members are in the play?
Answer:
there are 16 cast members.
Step-by-step explanation:
7(210-c)=1358 multiply everything in the parentheses by 7
1470-cx=1358
-7c=-112 subtract 1470 from both sides
c=16 divide -112 by -7
c=16
