CLOTHING A online retailer is running a special on jeans. All pairs of jeans are $39. The function f(x) = 39x models the total cost of buying x pairs of jeans. The retailer also charges $6 flat rate shipping fee. a. Write a function g(x) that represents the cost of purchasing jeans and having them shipped. b. Find the cost of purchasing 3 pairs of jeans before and after shipping
Answers
Answer:
a. g(x) = 39x + 6
b. The price before shipping is $117 and the price after shipping is $123
Step-by-step explanation:
To represent the cost of purchasing jeans and shipping them, add 6 to the function, since it is a flat rate.
So, the function will be g(x) = 39x + 6.
Then, use this function to find the cost of 3 pairs of jeans after shipping:
g(x) = 39x + 6
g(3) = 39(3) + 6
g(3) = 117 + 6
= $123
Then, use the original function, f(x) = 39x, to find the price before shipping:
f(x) = 39x
f(3) = 39(3)
= $117
So, the price before shipping is $117 and the price after shipping is $123
Meg laid 15 tiles in 50 minutes.
Jessica worked for 85 minutes at a faster rate per tile than Meg.
Choose all the rates that could be Jessica’s rate.
A: 20 tiles in 85 minutes
B: 24 tiles in 85 minutes
C: 28 tiles in 85 minutes
D: 1 tile in 3 minutes
E: 1 tile in 4 minutes
Answers
Answer:
I think C and E
Step-by-step explanation:
meg played at lace of 3.3333 tiles a minute so has to be over 25 tiles
The correct options are C and D.
Important information:
Meg laid 15 tiles in 50 minutes.Jessica worked for 85 minutes at a faster rate per tile than Meg.Rates:The rate per tile of Meg is:
[tex]\text{Rate}=\dfrac{\text{Time}}{\text{No. of tiles}}[/tex]
[tex]\text{Rate}=\dfrac{50}{15}[/tex]
[tex]\text{Rate}=3.333...[/tex]
Calculate the rates per tile for each option.
[tex]\frac{85}{20}=4.25[/tex]
[tex]\frac{85}{24}=3.54167...[/tex]
[tex]\frac{85}{28}=3.0357...[/tex]
[tex]\frac{3}{1}=3[/tex]
[tex]\frac{4}{1}=4[/tex]
From the above calculation is clear that the time spent per tile is less than Meg's rate in options C and D.
Therefore, the correct options are C and D.

A sofa regularly sells for $710. The sale price is $553.80. Find the percent decrease of the sale price from the regular price.
Answers
Given:
A sofa regularly sells for $710.
The sale price is $553.80.
To find:
The percent decrease of the sale price from the regular price.
Solution:
We have,
[tex]Decrease\%=\dfrac{\text{Regular price - Sale price}}{\text{Regular price}}\times 100[/tex]
[tex]Decrease\%=\dfrac{710-553.80}{710}\times 100[/tex]
[tex]Decrease\%=\dfrac{156.2}{710}\times 100[/tex]
[tex]Decrease\%=0.22 \times 100[/tex]
[tex]Decrease\%=22\%[/tex]
Therefore, the percent decrease of the sale price from the regular price is 22%.

What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a quadratic equation:
3x² + 4x = - 5
or
3x² + 4x + 5 = 0
D = b² - 4ac
b = 4, a = 3, c = 5
D = (4)² - 4(3)(5)
D = 16 - 60
D= -44
D < 0
Two complexes (nonreal) solutions
Thus, the quadratic equation has two complexes (nonreal) solutions option (B) is correct.

Given: ΔABC
m∠1=m∠2
D∈ AC , BD = DC
m∠BDC=100°
Find: m∠A, m∠B, m∠C
Answers
Answer:
m∠A = 60°, m∠B = 80°, m∠C = 40°Step-by-step explanation:
Since BD = DC, the triangle BDC is isosceles, so
m∠C = m∠2Having m∠BDC = 100°, we can find m∠C
m∠C = 1/2(180° - 100°) = 1/2(80°) = 40°Finding angle B
m∠B = m∠1 + m∠2 = 2*m∠2= 2*40° = 80°Finding angle A
m∠BDA = 180° - m∠BDC = 180° - 100° = 80°m∠A = 180° - (m∠1 + m∠BDA) = 180° - (40° + 80°) = 180° - 120° = 60°Answer:
m<A=60 degrees, m<B=80 degrees, m<C=60 degrees.

What is the circumference
Answers
Answer:
In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.
Step-by-step explanation:
Answer:
1. Circumference = 87.92
2.Circumference = 43.96
Step-by-step explanation:
The first problem it had a radius. So in order to find the circumference you will have to use the formula 2πr. When you plug in the 14 yd in the radius spot it will look like 2π(14) when you solve it the answer will be 87.92
The second one has a diameter so the equation you will have to use is πd. Now you will have to plug the 14 cm where the diameter is which will look like π(14) when you solve it the answer will come out as 43.96
