Which is a better deal?
An ice company charged $6.02 for 7 bags of ice. If a
convenience store sold 6 bags of ice for $5.52, which is a
better buy?
Explain/Justify your answer

Answers

Answer:

The $6.03 for 7 bags of ice is a better deal

Step-by-step explanation:

In order to find out which is a better deal we find the unit price.

To find the unit price we do the cost divided by how many bags of ice.

6.02 divided by 7 = 0.86, so the unit price is 0.86/1

5.52 divided by 6 = 0.92, so the unit price is 0.92/1

Finally, we can see which has a lower unit price which is the $6.03 for 7 bags of ice

Diego is buying shrimp and rice to make dinner. Shrimp
costs $6.20 per pound and rice costs $1.25 per pound.
Diego spent $10.55 buying shrimp and rice.
The relationship between pounds of shrimp s, pounds
of rice r, and the total cost is represented by the
equation 6.20s + 1.25r= 10.55.
Write an equation that makes it easy to find the number
of pounds of rice if we know the number of pounds of
shrimp purchased.

Answers

Answer:

r=  (10.55−6.20s)

--------------------------

         1.25

​  

 

Step-by-step explanation:

Using the principle of subject of formula, we make number of pounds of rice, r the subject of the given equation. Hence, the equation would be r = (10.55 - 6.20s)/1.25

Given the expression :

6.20s + 1.25r = 10.55

Isolate 1.25r

1.25r = 10.55 - 6.20s

Divide both sides by 1.25 to isolate r

r = (10.55 - 6.20s)/1.25

Therefore, the required expression would be

r = (10.55 - 6.20s)/1.25

Find the x- and y-intercepts of the graph of the equation.
f(x) = 4x – 12
x-intercept
(x, y) =
y-intercept
(x, y) =

Answers

Answer:

x intercept is (3, 0).  y intercept is (0, -12).

Step-by-step explanation:

x intercept is when y = 0.  [f(x) = y]  So 0 = 4x - 12. Solving for x gives you a value of 3.  [12 = 4x; divide by 4]

y intercept is when x = 0.  So y = 4(0) - 12.  Solving for y gives you a value of  -12.  [y= 0 - 12; y = -12]

Step-by-step explanation:

The system of equations for this is

35 + .10x

18 + .3x

where x = the number of text messages

Usually, you would use substitution or elimination to solve this problem. However, because the answer choices were given, you can just plug in the values.

When you plug in 85, or x = 85, you get 43.5 for both equations because

35 + .10(85) = 43.5     18 + .3(85) = 43.5

Therefore, the answer would be 85 messages becuase both plans will cost the same when you send 85 text messages!

How do you solve -2 1/2+3/4÷3/8

Answers

Step-by-step explanation:

1. use PEMDAS (Parentheses, Exponent, Multiplication & Division, Addition & Subtraction). you would do 3/4 divided by 3/8 first.

  3/4 / 3/8 = 2  

2. add 2 to -2 1/2 (or if it's easier to understand, do 2 minus 2 1/2)

  -2 1/2 + 2 = -1/2     OR       2- 2 1/2 = -1/2

answer is -1/2

Find the area under the standard normal curve that lies outside the interval between following two values. Round the answers to at least four decimal places. (a)Find the area under the standard normal curve that lies outside the interval between -1.43 and 1.34.

Answers

Answer:

A = 0,16644

Step-by-step explanation:

The area (A₁) under the bell shape curve, from the left tail up   to the point ( z score) 1,34  is:

For  z (score ) = 1,34       A₁ = 0,9099

The area A₂  from the left tail up to z = -1,43 is

A₂ = 0,07634

Area A₂ is inside area A₁, the area A₃ inside the points - 1,43 and 1,34 is

A₃ = A₁ - A₂

A₃ = 0,9099 - 0,07634

A₃ = 0,83356

Finally area outside the interval  - 1, 43 and  1,34 is A ( the area we were looking for) is

A = 1 - A₃

A = 1 - 0,83356

A = 0,16644
