Robert sold 6 more magazine subscriptions the second week than he sold the first week. He sold twice as many the third week as he sold the first. If he sold 94 magazine subscriptions in all, how many did he sell the second week?
Answers
Answer:
22
Step-by-step explanation:
let 1st week magazines sold be x
number of magazines sold in 2nd week is 6 more than 1st week that is (x+6)
number of magazines sold in 3rd week is double of 1st week that is 2x
total=94
x+(x+6)+2x=94
x+x+6+2x=94
4x=94-6
4x=88
x=88/4
x=22
Which equation could be solved using this application of the quadratic formula?

Answers
Answer:
C. x^2 + 2x - 1 = 3
Step-by-step explanation:
The standard form of a quadratic equation is
ax^2 + bx + c = 0
We need to use the quadratic formula and the given expression to find the values of a, b, and c.
The quadratic formula is
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
Where the formula has -b, the problem has -2, so b = 2.
Now we have
ax^2 + 2x + c = 0
In the denominator, where the formula has 2a, the problem has 2(1), so a = 1.
Now we have
x^2 + 2x + c = 0
Inside the root, the quadratic formula has -4ac. the problem shows -4(1)(-4). Since we already know that a = 1, then c = -4.
Now we have
x^2 + 2x - 4 = 0
Let's look at choice A.
x^2 + 1 = 2x - 3
Subtract 2x from both sides. Add 3 to both sides.
x^2 - 2x + 4 = 0 This is not it!
Let's look at choice B.
x^2 - 2x - 1 = 3
Subtract 3 from both sides.
x^2 - 2x - 4 = 0 This is not it!
Let's look at choice C.
x^2 + 2x - 1 = 3
Subtract 3 from both sides.
x^2 + 2x - 4 = 0 This is it!
Answer: C. x^2 + 2x - 1 = 3

Option D is correct.
What is quadratic equation?A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is [tex]ax^{2} +bx +c =0[/tex], where a and b are the coefficients, x is the variable, and c is the constant term.
Quadratic formulaThe quadratic formula is used to find the roots of a quadratic equation.
[tex]x=\frac{-b \pm \sqrt{b^{2} -4ac} }{2a}[/tex]
According to the question
[tex]x=\frac{-2 \pm \sqrt{2^{2} -4(1)(-4)} }{2.1}[/tex]
We all know the quadratic formula for finding the factors of a quadratic equation
[tex]x=\frac{-b \pm \sqrt{b^{2} -4ac} }{2a}[/tex]
By comparing two formulas we get a = 1, b = 2, c = -4
Standard form of quadratic equation is [tex]ax^{2} +bx +c =0[/tex]
Substitute a = 1, b = 2, c = -4 in the standard form of quadratic equation
⇒ [tex]x^{2} +2x-4=0[/tex]
We can write it as
⇒ [tex]x^{2} +2x -1=3[/tex]
[tex]x^{2} +2x -1=3[/tex] equation could be solved using this application of quadratic formula.
Option D is correct.

a metal pipe is 77 cm long the inner diameter of the cross section is 4 cm and the outer diameter is 4.8 cm find the (i) inner curved surface area (ii) outer curved surface area (iii) total surface area
Answer with full step by step explaination
Answers
Answer:
Step-by-step explanation:
outer area=
first need to find the circumference of outer diameter
= π×4.8
= 15.079644.... cm
to find the outer curved area you would then do
= 77×15.079644
(ii) =1161.13264 cm²
inner curve area
circumference= π×4
=12.5663706.... cm
77×12.5663706
(i) =967.610537 cm²
total surface area=
as the outer and inner curved areas are already found only the top and bottom surfaces need to be
= area of larger circle
=π×4.8²
=72.382294.... cm²
smaller circle
=π×4²
=50.2654824.... cm²
72.382...-50.265
=22.1168116 x 2
=44.2336232 cm²
total surface area
(iii)= 2172.9768 cm²

You may not use Law or Sines to solve the problem.
Answers
Answer:
15 mStep-by-step explanation:
Refer to attached picture
The height = hAngles of elevation 22.6° and 38.3°Closer distance = dUse tangent to solve
tan 22.6° = h/(d + 17) ⇒ h = (d + 17) tan 22.6° ⇒ h = 0.42(d + 17)tan 38.3° = h/d ⇒ h = d tan 38.3° ⇒ h = 0.79dCompare the equations above and find the value of d:
0.42(d + 17) = 0.79d0.42d + 7.14 = 0.79d0.79d - 0.42d = 7.140.37 d = 7.14d = 7.14/0.37d = 19.3 mNow find the value of h:

You have to make 17 1/2 and 10 1/8 into improper fractions, which would be 35/2 and 81/8. Then you have to find a common denominator, which is 16, so you get 280/16 - 162/16. You subtract and get 118/6, which simplifies to 7 3/8. Hope this helps :)
