36 is 90 percent of 40.
We have,
To determine what percentage 36 represents in relation to the whole value of 40.
To do this, we use the formula for finding a percentage:
Percentage = (Part / Whole) x 100
In this case, the part is 36, and the whole is 40.
By substituting these values into the formula, we get:
Percentage = (36 / 40) x 100
Simplifying the calculation:
Percentage = 0.9 x 100
Percentage = 90
This means that 36 is equal to 90% of 40.
In other words, 36 represents 90% of the totalvalue of 40.
Thus,
36 is 90% of 40.

Answer:
half hour= 2 and one half mile
whole hour= 5 miles
Step-by-step explanation:
half hour 12 24 36 two miles and 12 divided by 2 is 6 so 2 and a half miles
whole hour 12 24 36 48 60 is 5 miles

a. Find measurements in yards and miles for distances by filling in the table.
distance measured in miles
distance measured in yards
1
5
3,520
17,600
b. Is there a proportional relationship between a measurement in yards and a
measurement in miles for the same distance? Explain why or why not.
Therefore, the ratio of yards to miles is always constant, making it a proportional relationship.
An equation is a mathematical statement that shows the equality between two expressions. It typically includes one or more variables, which are unknowns that can take on different values. An equation can be solved by finding the value or values of the variable(s) that make both sides of the equation equal.
Here,
a. Using the equation y = 1760m, we can fill in the table as follows:
distance measured in miles distance measured in yards
1 1,760
5 8,800
3.520 6,195.2
17,600 30,800,000
b. Yes, there is a proportional relationship between a measurement in yards and a measurement in miles for the same distance. The equation y = 1760m shows that the number of yards is always 1760 times greater than the number of miles. This means that if you double the number of miles, the number of yards will also double, and if you triple the number of miles, the number of yards will triple, and so on.

Answer:
g = 12.8
Step-by-step explanation:
g/4 = 3.2
Multiply both sides by 4
g/4 * 4 = 3.2 * 4
g = 12.8
Answer: g = 12.8
Tim has a total of 30 nickels and 40 dimes.
Linear equations are the equations which consist of two or more variables having the exponent of the variable equals 1.
Total number of coins in the Tim's piggy bank = 70 coins
Let d be the number of dime coins and n be the number of nickel coins.
So d + n = 70
Total dollars = $5.50
10 dimes = 1 dollar
1 dime = 1/10 dollar = 0.1 dollar
20 nickels = 1 dollar
1 nickel = 1/20 dollar = 0.05 dollar
0.1 d + 0.05 n = 5.50
So we have two linear equations here : d + n = 70 and 0.1 d + 0.05 n = 5.50.
d + n = 70 ⇒ d = 70 - n
Substituting d = 70 - n in the equation 0.1 d + 0.05 n = 5.50,
0.1 (70 - n) + 0.05 n = 5.50
(0.1 × 70) - 0.1n + 0.05n = 5.50
7 - 0.05n = 5.50
-0.05n = -1.5
n = 30
So d = 70 - n = 70 - 30 = 40
Hence the number of nickel coins is 30 and number of dime coins is 40.
