Sharon buys four salmon steaks for $22.95 at her local supermarket. The weights of the steaks, in pounds, are 0.68, 0.74, 0.77, and 0.81. To the nearest cent, what is the price of salmon steak per pound?
Answer:
$7.65
Step-by-step explanation:
Given that:
Money used for buying the four salmon steaks = $22.95
Weights of steaks in pounds = 0.68, 0.74, 0.77, and 0.81
To find:
Price of salmon steak per pound, to the nearest cent = ?
Solution:
Total weight of all 4 steaks = 0.68 + 0.74 + 0.77 + 0.81 = 3
Here, to find the price of salmon steak per pound we need to divide the total money used to buy salmon steaks with the total weight of salmon steaks in pounds.
Price of salmon steak per pound = [tex]\frac{22.95}{3} = \$7.65[/tex]
If an arithmetic sequence
begins with a 6 and the constant term is 2, what would be the
fourth term of the sequence?
plsssss help
Answer:
a₄ = 12
Step-by-step explanation:
To obtain the terms in the sequence add 2 to the previous term, that is
a₂ = a₁ + 2 = 6 + 2 = 8
a₃ = a₂ + 2 = 8 + 2 = 10
a₄ = a₃ + 2 = 10 + 2 = 12

Choose the situation in which the use of approximate numbers is most appropriate.
A)
planting trees in your yard
B)
ordering chairs for a kitchen table
purchasing barbeque to serve at a party
D
ordering uniforms for the high school basketbalt team
Answer:
I would say that A is your answer.
I think this because you would not need to have any specific number of trees in your yard, but you would need a specific number of things for all of your other options.
Step-by-step explanation:
You probably wouldn't approximate on how many chairs you put in a kitchen. What if you have a 5-member family and you aproxomate the chair number to 4. that would be useless so B is wrong.
C is wrong because you are only getting 1 barbaque. no approximation is nessisary for one item.
D is certainly wrong because you wouldn't want to leave out a uniform, that would mean one member of the basketball team may not get one.
Solve this equation for x by graphing.
-4x - 1 = 5^x + 4
Please help! Asap
Answer:
-1.28
Step-by-step explanation:
You would put these two equations into a graphing ccalculator:
y = -4x - 1
and
y= 5^x + 4
Wherver they intersect is your answer.
These two happen to intersect at (-1.28,4.13)
Since the equation has x-values, you would give the first number (x-coordinate) as your answer.

Erica purchased adult and youth tickets for a movie. She bought x adult tickets for $7 each and y youth tickets for $5. Write an expression that can be used to show the total cost, C, of all tickets.
PLZ HELP IM FALING :o
i will give brainlyest
Answer:
C = 7x + 5y
Step-by-step explanation:
Algebraic Expressions
Erica purchased tickets for a movie. It's given each adult ticket cost $7 and each youth ticket cost $5.
If each adult ticket cost $7 and she bought x tickets, then she spent 7x dollars on adult tickets.
Similarly, if each youth ticket cost $5 and she bought y tickets, then she spent 5y dollars on youth tickets.
The total cost C is the sum of the individual costs, thus:
C = 7x + 5y

Most of the geometry concepts and theorems that are learned in high school today were first discovered and proved by mathematicians such as Euclid thousands of years ago. Given that these geometry concepts and theorems have been known to be true for thousands of years, why is it important that you learn how to prove them for yourself?
Answer:
self realization, confidence
Step-by-step explanation:
also these concepts are used in real life jobs but most people think otherwise because you dont use them in a grocery store... yeah people think that, but also its so these concepts that were figured out thousands of years ago dont fade away with the newer generations
What is the slope of the lines! HELP PLEASE!!! 20points
Answer:
1/5
Step-by-step explanation:
pick any points, for example (6, -1) and (11, 0)
slope is m= (y2-y1) / (x2-x1) = -1-0 / 6-11 = -1 / -5 = 1/5
Solve the equation for x and find the restrictions on the variable. Ax + bx = c

x = c/(A + b)
A + b ≠ 0

Step 1: Define
Ax + bx = c
Step 1: Solve for x
Factor: x(A + b) = cIsolate x: x = c/(A + b)We know that we cannot divide by 0, so A + b cannot equal 0.
Juan hires an electrician.
Juan pays a one-time fee of $30.
Juan also pays $45 for each hour the electrician works.
Write a function that can be used to find the total charge, c, Juan will pay when the electrician works,h, works
Answer:
c = 45h + 30
Step-by-step explanation
Hi! You know that you are trying to find the value of c, so you are going to set that as what would be your y value.
Now you know that you have to pay $30 as a fee no matter what, so you need to make sure that there is $30 attached to the equation without it being multiplied by anything.
Next, you know that it is $45 per hour, so you are going to multiply 45*h, where h is the number of hours the electrician works.
Hope this helps!
Write an equation for the following problem.
The cost of a babysitting service on a cruise is $10 for the first hour and $12 for each additional hour. If the total cost of
babysitting baby Aaron was $58, how many hours was Aaron at the sitter?
12x+10=58
10x+12=58
12x-58=10
10x+58=12
Answer: Aaron was at the sitter for 5 hours
Step-by-step explanation:
12x + 10 = 58
the 12x is for each hour after the first hour and the 10 is the first hour
-10 from each side
12x = 48
/12
x = 4
4 additional hours plus the original hour

The regular price is $8.45 more than the sale price. The regular price
is $24.95. What is the sale price? _____
Answer:
33.04
Step-by-step explanation:
just add lolz :P
Answer:
$33.40
Step-by-step explanation:
1 1 1
24.95
+ 8.45
__________
33.40
5+5 is 10 so bring a 1 to the top and put a 0 for the bottom
1+9+4 is 14 so put the 4 down and put the 1 on top.
1+4+8 is 13 so put the 3 down and put the 1 on top.
1+2 is 3 so put the 3 down
then you get 33.40

y = 4x 2 is shifted 5 units to the right
Answer:4
Step-by-step explanation: y=mx+b is the slope intercept form of an equation. m is the slope and b is the y-intercept. just substitute 4 for m and 2 for b and get the original equation y = 4x + 2. since 4 is m, then 4 is the slope.
Answer:
y= 4(x-5) 2
Step-by-step explanation:
It seems counterintuitive, but to shift a parabola, you have to subtract five from x. To shift to the left, you would simply add five to x instead of subtract.
The city of Austin has a bridge that is famous for housing the largest urban bat colony in the
world. It is home to 2 million bats. It has been determined that the bats eat a total of 10 tons
of insects a night. If the population of the bats increases to 2.5 million, about how many
insects would they consume?
Answer:
tons
Answer:
12.5 tons
Step-by-Step Explanation
There are 2 million bats and they eat 10 tons so 1 million bats would eat 5 tons half of 5 is 2.5 so if there where 2.5 million bats then you would increase the number of insects by half of a half or 2.5 because the number increased by half a million and 1 million bats eat 5 tons. Hope this was helpful :D
A complex number has a real part 4 and an imaginary part coefficient of -3. Which binomial is equivalent to this complex number?
Answer:
4-3i
Step-by-step explanation:
Here, we want to select the option that best correlate
The real and the complex part can be represented as;
a + bi
In this case, a is the real, b is the complex
So we have that;
Real part 4 and imaginary coefficient of 3
That will be
4 -3i
Answer:b
