A customer wants to buy 0.4 pounds of mulch that cost $5.20 per pound. If the customer has a coupon for $0.50 off the total cost, how much will they pay for the mulch?
$1.04
$1.58
$2.08
$4.16
The amount paid for 0.4 pounds of much after deducting $0.50 coupon is $1.58. option B
DiscountCost of each pound of mulch = $5.20Number of pounds of mulch bought = 0.4 Coupon = $0.50Cost of 0.4 pounds of mulch = xCost of mulch : pounds of mulch
5.20 : 1 = x : 0.4
5.20/1 = x/0.4
5.20 × 0.4 = 1 × x
2.08 = x
Cost of 0.4 pounds of mulch = x = $2.08
Amount paid for 0.4 pounds of much after deducting $0.50 coupon
= $2.08 - $0.50

Answer:
b) $1.58
Step-by-step explanation:
Now we have to,
→ find the amount the customer must pay.
One pound of mulch costs,
→ $5.20
Then 0.4 pounds of mulch costs,
→ $5.20 × 0.4
→ 5.20 × 0.4
→ $2.08
Total cost after reducing $0.50,
→ 2.08 - 0.50
→ $1.58
Hence, customer must pay $1.58.
Is 22/25 a terminating or repeating decimal
What is the answer okkkkkkkkkkk
Step-by-step explanation:
well,
23 < 12 + 0.04×x
11 < 0.04×x
11/0.04 < x
275 < x
x > 275 or x >= 276
so, for more than 275 monthly calls (that means 276 or higher) plan 1 is more economical.
at 275 calls is is plain even between both plans.
for fewer calls than 275 plan 2 is more economical.
Marline Was playing basketball and made 8⁄10Of the shots he took what decimal Number repeat Number repeat represents done fraction of shots Merlin made
The fraction ( 8/10 ) when converted into a decimal number is equal to 0.8.
The decimal number system is frequently used to express both integer and non-integer quantities. The Hindu-Arabic numeral system has been expanded to include non-integer values. Decimal notation is the name for the method used to represent numbers in the decimal system.
The number of shots fired by Marlin should be expressed as a decimal number.
We know that,
Marlin made 8 shots out of 10 shots which is in fraction, it is 8/10.
However, since we are dividing by 10, we shall shift the decimal point of 0.8 to the left (the zero is not really important as it only represents a place value )
Or,
( 8 /10) = ( 4 / 5 ) = 0.8
Therefore, the fraction of the shots Marlin made is 0.8.

your answer as a fraction.
June is 9 / 8 times as old as Tomasso in the question.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that Ferrera is 3/4 as old as June, and Tomasso is 1. 1/2 times as old as Ferrera.
The number of the times will be calculated as below:-
F = ( 3 / 4) J
T = 1 ( 1 / 2 ) F
T = ( 3 / 2 )F
Put the value of F in the second equation.
T = ( 3 / 2) ( 3 / 4 )J
T = ( 9 / 8)J
Therefore, June is 9 / 8 times as old as Tomasso in the question.

It's vote counting day for an election held in a country. The 3 TV stations updated the public about the number of votes cast starting at 7:00 in the morning. TV station A announces the vote counts every 2 hours, TV station B announces it every 3 hours, and TV station C announces it every 4 hours. At what time will the three TV stations announce the vote counts at the same time?
The 3 tv stations will announce the news again after 12 hours at 7 in the evening which is calculated by taking the LCM of the 3 intervals.
LCM or lowest common multiple of 2 or more numbers is defined as the minimum number which is lowest multiple of of the 2 or more numbers which is equal.
In mathematics and number theory. Since the result of dividing an integer by zero is not defined this definition only applies if both x and y are not equal to zero. However, given that 0 is the only common multiple of x and 0, some authors define LCM(x,0) as 0 for all x.
The intervals in which channels announce the news are 2 hours, 3 hours and 4 hours.
So we have to find the LCM of the numbers.
LCM(2,3,4)=12 as 12 is the smallest integer which is divided by all the other 3 numbers.
So the news channels will announce the news after 12 hours.
Since they announced at 7 in the morning so they would all announce the news again at 7 in the evening.

Addie's income by running a sandwich delivery service is given by the function y = 12x + 5, which has a domain and range of [0 , +∞) and [5 , +∞), respectively.
In mathematics, a function is the representation of the relationship of a set of input(X) and its corresponding output(Y). The set of x is called the domain while the set of the corresponding y is the range.
If Addie runs a sandwich delivery service. her income can be measured using the function
y = 12x + 5
where x = number of sandwiches she delivers
y = income
The domain of a function is the set of values that we are allowed to plug into our function. The domain of any function of x is always the set of all real numbers but, reasonably speaking, we must consider the situation given. The number of sandwiches she delivers can only range from 0 to positive infinity, not negative.
domain : {x | x ≥ 0} or [0 , +∞)
On the other hand, the range of a function is the set of values of the function after plugging in the value of x.
Substituting our domain [0 , +∞) in the function.
y = 12x + 5
y = 12(0) + 5
y = 5
y = 12(+∞) + 5
y = +∞

What exactly is a pie chart?A pie is a kind of chart that displays data in the form of a circular graph.
We understand that the total value of the pie is always 100%. It is also understood that a circle does have a circumference of 360°. As an outcome, the total of all data points equals 360°. There appear to be mainly two pie chart formulas based on these:
To determine a percentage of a data set, we use the following format: 100 (Frequency ÷ Total Frequency) × 100To convert the information to degrees, we use the given equations: (Informed Data ÷ Total value of Data) × 360°When a circle is completely rotated, it forms a 360-degree angle in the center.
At the center of the circle, a complete rotation yields 360 degrees.
The total percentage of all colors is 100%.
Divide a value of green by 3.6 since 360 degrees / 100% = 3.6.
The total percentage of green displayed by the spinner's pointer is 80%.
P (probability of the cursor landing on green) = 80/3.6
Probability P (cursor landing on green) = 22.222... = 22.23 (approx.)
As a result, the probability which the pointer will land on the green is 22.23%.

Find the diameter of a circle with an area of 79 square feet.
The diameter of circle is 10.0 feet.
We are given the area of circle. The formula of area with respect to diameter is as follows -
Area = 1/4πd², where d represents diameter of circle.
Taking the value of π as 3.14.
Rewriting the equation according to diameter -
d² = (area×4)÷π
Now, keep the values in formula to find the diameter of circle.
d² = (79×4)÷3.14
Performing multiplication on the Right hand side of the equation
d² = 316÷3.14
Performing division on the Right hand side of the equation
d² = 100.6
d = √100.6
Taking square root on the Right hand side of the equation
d = 10.03 feet
Rounding to nearest tenth -

Given,
Here we need to find the value of x² values that separate the middle 80 % from the rest of the distribution for 20 degrees of freedom.
Based on the given details,
Degrees of freedom = 20
Middle separate value = 80%
Which is equal to 0.8 in decimal point.
The significance level
=> ∝ = 1 - 0.8
=> ∝ = 0.2
But we need the area of the middle so we divide this significance level with 2
so that we get exactly the middle area .
Dividing

How to solve an equation?To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
See, that was so simple, using the mentioned methods, every linear equation can be solved easily.
⇒ |3 x+9| = 11
For positive case
⇒ (3 x+9) = 11
⇒ 3x = 11 - 9
⇒ 3x = 2
⇒ x = 2/3
For negative case
⇒ -(3 x+9) = 11
⇒ -3x -9 = 11
⇒ -3x = 20
⇒ x = -20/3
