A machine can pack 80 cans in 5 minutes. Choose all of the values that show the ratio of cans to minutes.
Answer:
16 cans per minute
Step-by-step explanation:
Its simple 80 divided by 5 is 16 so ever minute 16 cans are packed.
The ratio of the cans to minutes is 80 : 5 or 16 : 1, and the machine can pack 16 cans per minute if a machine can pack 80 cans in 5 minutes.
What is the ratio?It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign: between the numbers.
A machine can pack 80 cans in 5 minutes.
let's denote the number of cans with X and
Time with T
So we have to find the value of X : T
X = 80 and
T = 5 minutes
X : T = 80 : 5 or
X : T = 16 : 1 (divide by 5 on both sides)
It means the machine can pack 16 cans per minute.
Thus, the ratio of the cans to minutes is 16 : 1, and the machine can pack 16 cans per minute if a machine can pack 80 cans in 5 minutes.

The shoes you want to buy are on sale for 25% off the original price is $75 what is the sale price of the shoes
Answer: $56.25
Step-by-step explanation:
25 as a decimal is 0.25
So you multiply 0.25 * 75 = 18.75
75 - 18.75 = 56.25
The sale price of the shoe is $56.25.
What is the area of a circle with a diameter of 18.2 cm?
Use 3.14 for ∏ and round your final answer to the nearest hundredth.
The area is ___ square cm.
Answer:
260.02 cm²
Step-by-step explanation:
radius of circle= 18.2÷2
=9.1
area of circle= πr²
= 3.14×9.1²
= 260.02 cm² (nearest hundredth)
Answer:
Solution given:
diameter=18.2cm
[r]radius=diameter /2=18.2/2=9.1cm
Now
Area of circle=πr²=3.14*(9.1)²=260.02cm²
The area is _260__ square cm.

If 4x - 8 = 4 , find the value of x
Answer:
x=3
Step-by-step explanation:
4x-8=4
4x=12
4x/4=12/4
x=3
Answer:
x = 3
Step-by-step explanation:
Add 8 to both sides.
4x = 4 + 8
Simplify 4 + 8 to 12.
4x = 12
Divide both sides by 4.
x = 12 ÷ 4
Simplify 12 ÷ 4 to 3
x = 3
If a car can travel 250 miles on 10 gallons of fuel , how many gallons are requiered to travel 1325 miles
Answer:
53 gallons of fuel
Step-by-step explanation:
Step 1: Set up a fraction given the data (Let "x" represent the distance in miles.)
[tex]\frac{10}{250} = \frac{x}{1325}[/tex]
Step 2: Divide the given values (The given values are 10 over 250. We are doing this because we need to know the difference between those two figures.) (Trick: For this case, all you need to do is cancel both zeros and the answer is 0.04 once divided)
[tex]\frac{10}{250}\\\\10 \div 250\\\\= 0.04[/tex]
Step 3: Multiply the result to the last value (Since we've found the difference between them by division, we will have to do the opposite operation in order to find the answer.)
[tex]1325 \times 0.04\\\\= 53[/tex]
Therefore, 53 is the amount of gallons of fuel needed.
Everyone learns differently. Some people like to use models and tools to help them learn math concepts. Many people like to use a combination of these strategies. What tools and strategies do you use to help yourself learn new ideas in math?
Answer:
Kindly check explanation
Step-by-step explanation:
Learning could be explained as a process of acquiring knowledge about a certain subject, trade or other aspects of life. In terms of learning about certain school subjects, a student needs to discover him or herself in other to make acquiring knowledge easy and less tedious for him or her. Now, there are designated tools more than evwr which could aid learning. A very important recommendation which could aid acquiring matematicka knowledge is the use of models to gain an insight to the fundamentals of a mathematical problem and thus seeing how it works. After this one can then break down the mathematical procedure embedded or used it aid the model manually in other to grasp the full concept of the principle.

The total cost of a gym membership, C, in Australian dollars (AUD), in John's Gym can be modelled by the function C = 65t+30, where t is the time in months. Calculate the gym membership cost over 12 month duration
Answer:
810 AUD
Step-by-step explanation:
t is time in months: you have to substitute with the number of months given from the question.
C=65t + 30 ==> substitute t with 12 since the question provided you the number of months.
--> C = 65(12) + 30 = 780 + 30 = 810

If - 2x + 3 = 7 and 3x + 1 = 5+ y, the value of y is
Answer:
The value for x is -2 and the value for y is -10 .
Step-by-step explanation:
Firstly , let's write the equations
-2x+3=7 ( equation 1 ) 3x+1 =5+y (equation 2 )
solving equation 1 to get the values of x
or , -2x+3=7
or, -2x+3-3 =7-3 (subtracting -3 on both sides )
or , -2x=4
or, -2x/2 = 4/2 (dividing by two on both sides )
or , -x =2
or x = -2
now let's substitute the values of x in the equation 2
3x+1 =5+y (writing second equation as it is )
or, 3x+1-1=5+y-1 (subtracting -1 on both sides )
or , 3x = 4+y
or , 3 × -2 = 4+y (substituting the values of x from equation 1 )
or , -6 = 4 +y
or , -6-4 = 4+y-4 ( subtracting -4 on both sides )
or , -10 = y
Therefore the values of x and y is -2 and -10 respectively .

Roll needs to make a sauce mixture of 2/5 sand and 2/5 of clay and one for Pete Mas to put his plants yes 75 pounds of sand how many total pounds of soil rather have it he adds clay and Pete Moss to the sand to make the correction mixture
Answer:
187.5 pounds
Step-by-step explanation:
Fraction of sand = 2/5
Fraction of clay = 2/5
Fraction of peat = 1/5
Pounds of sand = 75
The total pounds of soil required to make Correct mixture : let that be x
Hence,
Using the sand Fraction and pounds which we know :
2/5 of x = 75
2x / 5 = 75
Cross multiply :
2x = 75 * 5
2x = 375
x = 375 / 2
x = 187.5
Required pond of sand =187.5 pounds

Expand the logarithm. Assume all expressions exist and are well-defined.
Write your answer as a sum or difference of common logarithms or multiples of common
logarithms. The inside of each logarithm must be a distinct constant or variable.
log 3y
Answer:
Step-by-step explanation:
log 3y = log(y)^3 (exponent)
or
= log(y)*log(y)*log(y) (multiples)
The logarithmic expression y = log(3y) can be written as sum or difference of common logarithms as log(3y) = log(3) + log(y).
What is logarithm? What is a mathematical function, equation and expression?logarithmic : It is a quantity representing the power to which a fixed number (the base) must be raised to produce a given number. Mathematically -[tex]$\log_{b}({b^x})=x[/tex] {where [b] is logarithmic base}
function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the following logarithmic expression as -
y = log(3y)
We have the following logarithmic expression -
y = log(3y)
Using the identity of logarithm -
log(AB) = log(A) + log(B)
log(3y) = log(3) + log(y)
Therefore, the logarithmic expression y = log(3y) can be written as sum or difference of common logarithms as log(3y) = log(3) + log(y).

-15 < 99 and | -9 | < | 15 |
Step-by-step explanation:
Those lines " | " refer to absolute value, meaning it is the distance from 0. You can easily get this just by cutting off a negative sign.
So we do know -9 is greater than -15 obviously, and the absolute value of -9 is 9, because -9 is 9 units from 0.
-15 is 15 units away, so when using absolute value, -15 is greater than -9.
Btw, you can only give one brainliest, you don't get the option to give two on brainly.
Just saying.
Idc if I get it honestly.

Explain to Raven what she did correctly in the first two problems that she did not do in the last problem, and how to correct her mistake
Answer:
She changed the symbols in the first two problems because they were divided by a negative number whereas she shouldn't have changed the symbol in the last problem as it was not divided by a negative number and so the sign remains the same.
what is the solution 6x-4 =2(3x-2)
Answer:
x= 0
Step-by-step explanation:
6x-4=2(3x-2)
or,6x-4=6x-4
or,x=o
There are infinite solution of the expression.
We have to given that,
An expression to solve,
6x - 4 = 2 (3x - 2)
Now, We can simplify as,
6x - 4 = 2 (3x - 2)
Apply distributive property,
6x - 4 = 6x - 4
Combine like terms,
6x - 6x = 4 - 4
0 = 0
Hence, There are infinite solution of the expression.
