Answers

Complete question :

A pair of $36 jeans were on sale at Jim's Jeans for 1/3 off. The same pair of jeans were $42 at David's Denims. The jeans were on sale for 2/3 off.

A.) which store had the better buy

B.) how much will you pay at the store that has the better buy

Answer:

A.)David's denim has the better buy

B.) $14

Step-by-step explanation:

Jim's Jean store :

Cost of Jean = $36

Discount = 1/3 off

Discounted cost = $36 - (1/3 * $36)

Discounted cost = $36 - $12 = $24

David's Denim:

Cost of Jean = $42

Discount = 2/3 off

Discounted cost = $42 - (2/3 * $42)

Discounted cost = $42 - $28 = $14

David's denim has the better buy with a discounted price lower than the discounted price at Jim's store.

Cost at store with the better buy is $14

Answer:

f=  

23/14

=1.643

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-11-(7*(1-2*f)+5)=0

-11 -  (7 • (1 - 2f) +  5)  = 0

14f - 23  = 0

3.1      Solve  :    14f-23 = 0  

Add  23  to both sides of the equation :  

                     14f = 23

Divide both sides of the equation by 14:

                    f = 23/14 = 1.643

Step-by-step explanation:

C

The change of the frequency of people waking up with respect to the sound level, 9% per 8 decibels.

What is linear function?

Linear function is the function in which the highest power of the unknown variable is one. Linear functions used to model the real life problem in the mathematical expressions.

The linear function with dependent variable y and independent variable x can be written as,

[tex]y=mx +c[/tex]

Here, (m) is the slope of the function and (c) is the y intercept.

The slope can be found out as,

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The sound level is plotted on x-axis and frequency of people walking up (%) is plotted on y-axis. The slope of the line given the rate of change of y values with respect to x value.

In the graph given, the frequency of people walking up is 10 at 55 decibels and 55 at 95 decibels. The point, we get for this line are (55, 10) and (95, 55). Therefore the slope or the change of rate is,

[tex]\dfrac{dy}{dx}=\dfrac{55-10}{95-55}\\\dfrac{dy}{dx}=\dfrac{45}{40}\\\dfrac{dy}{dx}=\dfrac{9}{8}[/tex]

Hence, the change of the frequency of people waking up with respect to the sound level, 9% per 8 decibels.

Hi

                      -x² +4x -3 = 0

To solve, tou have to use the general method of resolution of a quadratic fonction.  

To determine if it's has a solution in R, let's calculate  Δ

Δ = (4)² - 4 * (1) *(-3)

Δ = 16 +12

Δ= 28  

as Δ≥ 0  so  the function allow two solution within R  

so S 1 =  ( -4 +√28) / 2            S 2 =   (-4 -√28 ) /2

    S1 =   ( -4 + 2√7) /2            S2 =    (-4 - 2√7) /2

    S1 =    (2 (-2 +√7) /2            S2      2 (-2 -√7)   /2

    S1 =    -2 +√7                       S2 =      -2 -√7

So the two function  are equal   twice. one  for   x = -2 +√7  and second x = -2-√7

Answers

Answer:

125% correct

3/5 correct

2/3 correct

Step-by-step explanation:

Here, we want to pick the appropriate conversion from percentage to fraction:

To convert from percentage to fraction, we simply divide by 100

125% = 125/100 = 1.25 correct

30% = 30/100 = 0.3 not 0.03 wrong

1% = 1/100 = 0.01 not 0.001 wrong

60% = 60/100 = 3/5 correct

50% = 50/100 = 1/2 not 1/4 wrong

2/3 = 2/3 * 100 = 200/3 = 66.66667% correct

Students plan to pay back half the debt now though fundraising, and the rest after the harvest. Write an equation to represent the debt they will repay through fundraising. Use a negative integer to show debt. Use "D" to represent the debt that will be repaid by through fundraising.

Answers

Answer:

D =  [tex]\frac{-d}{-2}[/tex]

Step-by-step explanation:

The students in this question are trying to pay back only half of the current debt (d) with the fundraiser (D). Since debt is money that is owed it would therefore be represented as a negative but in this case the fundraiser needs to be positive since it is money gained. So since we have a negative we would need to divide by -2  in order for the total to be positive.

D =  [tex]\frac{-d}{-2}[/tex]

Finally, we are left with this equation which shows the debt that will be repaid through the fundraiser

if a football is thrown upward, its height above the

ground is given by the equation s=-16t^2+Vot+so, where

Vo and so are the initial velocity and intial height of the

Football, respectively, and t is the time in seconds.suppose

the football is thrown from the top of a building that is

192 feet tall, with an initiae speed of 96 feet per second.

a)write the polynomial that gives the height of the Football in terms

of the variable t (time)

b) what is the height of the Football after 2 seconds have

Clapsed? Will the football hit the ground after 2 seconds?

Answers

Answer:

a) s = -16[tex]t^{2}[/tex] + 192t + 96

b) Height of the football after 2 seconds is 448 feet.

ii. The football would not hit the ground after 2 seconds.

Step-by-step explanation:

Given:

s = -16[tex]t^{2}[/tex] + [tex]V_{o}[/tex]t + [tex]s_{o}[/tex]

where: s is the height of the football above the ground, t is the time, [tex]V_{o}[/tex] is the initial velocity and [tex]s_{o}[/tex] is the initial height.

The height of the building = [tex]V_{o}[/tex] = 192 feet and the initial speed of the ball = [tex]s_{o}[/tex] = 96 feet per second, then;

s = -16[tex]t^{2}[/tex] + 192t + 96

a) The polynomial is given as:

s = -16[tex]t^{2}[/tex] + 192t + 96

b) The height of the football when t = 2 seconds is;

s = -16(2) + 192(2) + 96

 = -32 + 384 + 96

 = -32 + 480

s = 448

The height of the football when t = 2 seconds is 448 feet.

ii. The football would not hit the ground after 2 seconds.

So a is 3 times 4/2=12/2=6 sq ft.

b is 6 times 5/2=30/2=15

Answer:

Step-by-step explanation:

A = [tex]A_{1}[/tex] + [tex]A_{2}[/tex]

[tex]A_{1}[/tex] = (5 × 6) ÷ 2 = 15 ft²

[tex]A_{2}[/tex] = (4 × 3) ÷ 2 = 6 ft²

4 2/3 cups of water

Step-by-step explanation:

The original recipe has 3 1/2 cups of potatoes and 3 1/4 cups of water.

4.

If you put 5 cups of potatoes, you can find the amount of water you need using a proportion.

3 1/2 cups of potatoes is to 3 1/4 cups of water as 5 cups of of potatoes is to x cups of water.

(3 1/2) / (3 1/4) = 5/x

(7/2) / (13/4) = 5/x

7/2 * x = 13/4 * 5

2/7 * 7/2 * x = 2/7 * 13/4 * 5

x = 130/28

x = 65/14

x = 4 9/14

4 9/14 as a decimal is 4.64 which is close to 4.6666...
