Jeremie bought 5 pounds of bananas for $4.45. How much is 1 pound of bananas? Show or explain your reasoning
what is the strategies for this math problem?
Answer:
1 pound of bananas is 0.89
Step-by-step explanation:
Money over quantity 4.45/5
that means you divide so heres the layout
4.45/5 = x/1 so that is
5x=4.45 divide 5 so that gives us our variable 5÷5 that cancels out five 4.45 divide by 5 is 0.89
so for every pound of bananas is 0.89
And you would use Unite Rate as your strategy
Answer:
for 1 pound of banana...it is 0.89
Step-by-step explanation:
for 5 pound=4.45
for 1 pound =?(x)
5x=4.45×1
x=4.45/5
x=0.89

The perimeter of a rectangle is 194. The length is 25 more than 5 times the width. Find the dimensions.
Answer:
12 and 85Step-by-step explanation:
GivenP = 194l = 5w + 25l = ?, w = ?SolutionPerimeter formula
P = 2(l + w)Substitute and solve for w:
194 = 2(5w +25 + w)194 = 12w + 5012w = 144 w = 144/12w = 12Find the length:

Solve the simultaneous equations
X + y = 8
3x - y = 12
X =
y =
Answer:
y= -6
x=14
Step-by-step explanation:
in attachment
Answer: (5,3)
Step-by-step explanation:
Solve by Addition/Elimination
x + y = 8
3x − y = 12
Add the two equations together to eliminate y from the system.
x + y = 8
+ 3x −y = 12
4x = 20
Divide each term in 4x = 20 by 4.
4x = 20
4 4
Cancel the common factor of 4.
x= 20/4
x = 5
Substitute the value found for x into one of the original equations to solve for y.
(5) + y = 8
Remove parentheses.
5 + y = 8
Move all terms not containing y to the right side of the equation.
Subtract 5 from both sides of the equation.
y = 8 − 5
Subtract 5 from 8.
y = 3
The solution to the independent system of equations can be represented as a point.
(5, 3)
The result can be shown in multiple forms.
Point Form:
(5, 3)
Equation Form:
x = 5, y = 3
Currently there are 691,255 trees in a national forest. A park ranger discovered that an untreatable disease is killing the
trees at a rate of 1.5% every year.
Lett represent the number of years after the current date. Determine the inequality that can be used to model when there
will be no more than 621,859 trees, and then solve the inequality for t.
The inequality which will represent the disease killing of trees in the national forest is 691255[tex]0.985^{t}[/tex]<621859 and the value of t is t<7.
What is inequality?An inequality is just like an equation which is presented in greater than sign, less than signs. It also shows relationship between variables like an equation does.
How to form inequality?Total trees present in the beginning=691255
rate at which trees are killed by untreatable disease=1.5%
So the inequality can be formed as under:
691255[tex](1-0.015)^{t}[/tex]<621859
[tex](0.985)^{t}[/tex]<621859/691255
[tex](0.985)^{t}[/tex]<0.89960
[tex](0.985)^{t}[/tex]<[tex](0.985)^{7}[/tex]
By equating we find that t<7.
Hence if 691255 trees are present in the beginning then they will last for more than 7 years to reach 621859.

14 candy bars cost $5.20. How much would one cost? What is the unit rate?
Answer:
$0.37
Step-by-step explanation:
You can write this equation as, x=$5.20÷14.
This is because we know we are trying to find the x value for 1 candy bar. and 14 costs $5.20 in total. 14÷14=1. Therefore, we essentially divided the total sum among each individual candy bar. (example: if you wanted to find the value of 2 candy bars, you would take half of 14 and divide $5.20 by 7). $5.20÷14=$0.37 or 37 cents per candy bar.
Writing this as a rate is simple; it's $0.37/candy bar

B. City P is above sea level and City R is below sea level
Step-by-step explanation:
A. City R is negative meaning it is below sea level however City Q is 0 meaning it is at sea level, so this statement is false.
C. Once again, City P is positive meaning it is above sea level but City Q is 0 meaning it is at sea level, so this statement is false.
D. Like before, City P is above sea level and City Q is at sea level not below, so this is, once again, false.
a fair coin is tossed 3 times. What is the approximate probability of heads apppearing atleast one time
Possible outcomes of a coin toss are a head or a tail.
Since the coin is tossed three times, there'll be six possible outcomes.

If a new jacket sells for $37, find the total cost if you were charged 4% sales tax. Round your answer to the nearest cent.
Answer:
$38.48
Step-by-step explanation:
To find the sales tax you add 4% to 100%, which is 104%
Then you turn that into a fraction, which is 104/100
Then you multiply 104/100 by 37
You should get 38.48

since it's HALF the paper, the area should be the same. If you said the width of the paper was 8 inches and the length was 10, then the area would be 80 inches squared. Cut it in half for Calvin's paper and the area would be 40 inches squared, the same with Matthew's.
