Susan purchased a prepaid phone card for $15. Long distance calls cost 14 cents a minute using this card. Susan used her card only once to make a long distance call. If the remaining credit on her card is $9.26, how many minutes did her call last?
Answer:
41 minutes
Step-by-step explanation:
Step one:
given data
Susan purchased a prepaid phone card for $15
let the number of minutes be x
and let the total be y
per minute call cost = 14 cents = $0.14 per minute
Hence the expression for the situation is given as
y= 15-0.14x
Step two:
given that the balance after a call is 9.26
9.26=15-0.14x
solve for x
9.26-15= -0.14x
5.74=0.14x
divide both sides by 0.14
x=5.74/0.14
x=41 minutes

In is shopping for a couch with her dad and hears him ask the salesperson, "How much is your commission?" The salesperson says that her commission is five and a half percent of the selling price. The salesperson will earn $27.23 by selling a couch for $495 to Lin and her dad.
Answer:
A. $27.23
B. $467.77
Step-by-step explanation:
Lin is shopping for a couch with her dad and heard him ask the salesperson “how much is your commission?” The salesperson says that her commission is 5 1/2% of the selling price. A.How much commission will the salesperson earn by selling a couch for $495?
B.How much money will the store get from the sale of the couch?
Salesperson commission = 5 1/2%
Price of couch = $495
A. Amount earned by the salesperson = 5 1/2% of $495
= 5.5% × 495
= 0.055 × 495
= 27.225
Approximately
Amount earned by the salesperson = $27.23
B.How much money will the store get from the sale of the couch?
Amount the store get = Total price - amount earned by salesperson
= $495 - $27.23
= $467.77
I wasn't in class so I need help solving the inequality 7/10n+14<49
Answer:
n<50
Step-by-step explanation:
7/2*5n + 14<49
7n/2*5+14<49
(7n)+(2*5)14/2*5 <49
7n+10*14/2*5 <49
7n+140/2*5 <49
7n+140/10 <49
7n+140 < 10*49
7n+140 < 490
(7n+140)+(-140)<490+(-140)
7n+140-140<490-140
7n<350
7n/7 < 350/7
n<2*5^2*7/7
n<2*5^2
n<2*25
n<50

© ABCD is a rectangle with sides 6 cm and
8 cm. If its diagonals cross at X, the length
of AX is
Answer:
10
Step-by-step explanation:
If the sides of the rectangle is 6cm and 8cm, then we mean that, the length and breadth are 6cm and 8cm
The diagonal which cross at AX will be the hypotenus of the triangle formed by drawing the diagonal.
Hence,
Hypotenus = sqrt (opposite² + adjacent²)
AX = sqrt[(8²) + (6²)]
AX = sqrt(64 + 36)
AX = sqrt(100)
AX = 10

Carol bought two chairs with triangular backs. For what value of x can you use
a triangle congruence theorem to show that the triangles are congruent?
Which triangle congruence theorem can you use? Explain.
Answer:
x = 4
Step-by-step explanation:
Two sides, GH and GI, in ∆GHI are of the same side length as corresponding two sides, TU and TV, in ∆TUV.
To prove that both triangles are congruent using the SSS Congruence Theorem, therefore, the their third sides, HI and UV must be equal.
Therefore,
9x - 21 = 15
Add 21 to both sides
9x - 21 + 21 = 15 + 21
9x = 36
Divide both sides by 9
x = 4
Solve the algebraic equation -4x +2 (x - 1)^2
Answer:
2x^2 - 8x + 2
Step-by-step explanation:
-4x + 2(x-1)^2
= -4x + 2(x^2 -2x +1)
= -4x + 2x^2 - 4x + 2
= -8x + 2x^2 + 2
=2x^2 - 8x + 2 (usually put the exponent kind of things first)
Joel ordered a set of beads. He received 40 40 beads, and 60 % 60% of them were blue and 40 % 40% of them are green. How many blue beads did Joel receive?
Answer:
24 blue beads
Step-by-step explanation:
The number of blue beads is calculated as:
Percentage of blue beads × Total number of beads
Total number of beads = 40 beads
Hence:
= 60% × Total number of beads
= 60% × 40
= 60/100 × 40
= 24 blue beads
Joel received 24 blue beads.
Which number like inequality represents n<-1?
someone please do this for me:(
Answer:
Step-by-step explanation:
2x⁵ + 3x²- 2 → Quintic trinomial
12x → Linear monomial
7x³ -1 → Cubic binomial
3 - 4x → Linear binomial
4x - 5x³ + 1 → Cubic trinomial
2x²(x³ - 1) = 2x⁵ - 2x² → Quintic binomial
x²(4x - 1 + x²) = 4x³ - x² + x⁴ → Quartic trinomial
(x - 2)(x + 3) = x² + x - 6 → Quadratic trinomial
(x² - 1)(x² + 1) = x⁴ - 1 → Quartic binomial

On a coordinate plane, the center of a circle P is at the point (2, 15) . Point M is located on the circle at (7, 3). Which equation describes circle P?
Answer: (x - 2)^2 + (y - 15)^2 = 13^2
Step-by-step explanation:
We know that the general equation for a circle is:
(x - a)^2 + (y - b)^2 = R^2
Where:
(a, b) is the center of the circle
R is the radius of the circle.
First, we know that the center of the circle is the point P, (2, 15)
Now, we also know that point M, (7, 3), is located at the circle.
Then we know that the radius of the circle will be equal to the distance between point P and point M.
Remember that the distance between two points (a, b) and (c, d) is:
Distance = √( (a - c)^2 + (b - d)^2)
Then in our case, we have:
Distance = √( (2 - 7)^2 + (15 - 3)^2) = √(25 + 144) = 13
This means that the radius of the circle is R = 13.
Now we know the radius of the circle and the center of the circle, then we can write the equation of the circle as:
(x - 2)^2 + (y - 15)^2 = 13^2

Can I get some help here?
Answer:
AB, CB, AC
Step-by-step explanation:
All the angles in a triangle added up equal 180 degrees
Start by finding the measure of angle A
A + 86 + 27 = 180
A + 113= 180
A = 67 degrees
Now order them
86 is greater than 67 and 27 so B is the greatest
27 is less than 86 and 67 so C is the smallest
67 is less than 86 but greater than 27 so A is in the middle
Now for the sides..
AB is opposite angle C so it's the shortest
CB is opposite angle A so it's in the middle
AC is opposite angle B so it's the longest
