you can do 90 sit-ups in 2 minutes your friend can do 135 sit-ups in 3 minutes do these rates form a proportion ? Explain
Thus, the rates form a proportion as the rates of both are equal.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
The unit rate of sits-up = 90 / 2 = 45 sits-up per minute
Friend unit rate of sits-up = 135 / 5 = 45 sits-up per minute
From the above expressions, it is clear that rates form a proportion as rates of both are equal.

A single tree produces about 2.6 × 10² lb of oxygen each year. The Amazon rainforest has about 3.9×[tex] 10^{11} [/tex] trees.
About how many pounds of oxygen are produced in the rainforest each day ?
Enter your answer in the box.
2.8 × 10
lb
The approximate number of pounds of oxygen produced in the Amazon rainforest each day is [tex]\(2.8 \times 10^{10}\)[/tex] pounds.
To find out how many pounds of oxygen are produced in the Amazon rainforest each day, we first need to calculate the total amount of oxygen produced by all the trees in the rainforest annually.
The Amazon rainforest has about [tex]\(3.9 \times 10^{11}\)[/tex] trees, and each tree produces [tex]\(2.6 \times 10^2\)[/tex] pounds of oxygen per year.
So, the total amount of oxygen produced annually in the rainforest is:
[tex]\[ 3.9 \times 10^{11} \, \text{trees} \times 2.6 \times 10^2 \, \text{lb/tree/year} \][/tex]
To multiply these numbers, we can add the exponents and multiply the coefficients:
[tex]\[ (3.9 \times 2.6) \times (10^{11} \times 10^2) \, \text{lb/year} \][/tex]
[tex]\[ = 10.14 \times 10^{13} \, \text{lb/year} \][/tex]
Now, to find out how many pounds of oxygen are produced each day, we need to divide the annual total by the number of days in a year.
There are 365 days in a year, so:
[tex]\[ \text{Pounds of oxygen produced per day} = \frac{10.14 \times 10^{13} \, \text{lb/year}}{365 \, \text{days/year}} \][/tex]
[tex]\[ \text{Pounds of oxygen produced per day} = \frac{10.14 \times 10^{13}}{365} \, \text{lb/day} \][/tex]
To simplify, we divide the coefficient by 365:
[tex]\[ \text{Pounds of oxygen produced per day} = \frac{10.14}{365} \times 10^{13} \, \text{lb/day} \][/tex]
[tex]\[ \text{Pounds of oxygen produced per day} \approx 2.78 \times 10^{10} \, \text{lb/day} \][/tex]
Therefore, the approximate number of pounds of oxygen produced in the Amazon rainforest each day is [tex]\(2.8 \times 10^{10}\)[/tex] pounds.

A cat eats 2/3 cup of food each day. How many days will a bag containing 16 cups of food last?
To calculate how long a bag of food will last for a cat eating 2/3 cup of food each day, divide the total cups in the bag by the daily consumption amount, resulting in 24 days.
A bag of 16 cups of food will last for 24 days if a cat eats 2/3 cup of food each day. To find the number of days the food will last, you need to divide the total number of cups in the bag by the amount consumed per day: 16 cups ÷ (2/3 cup/day) = 24 days.

math mate problem
I have $100 which I wish to buy exactly 100 animals to feed to my snake. succulent mice cost $5, large Juicy fresh cockroaches are $1, and imported flies are $0.05 each .if I spend every cent buying these animals and I buy at least one of each how many cockroaches will I buy?
The number of co.ck.roaches that one can buy is given as: 95
It is to be noted that this was solved using the knowledge of Algebraic Equations.
An algebraic equation is one where two mathematical statements are equated to one another. See how we arrive at the answer using algebra statements below.
What is the solution to the question?Let us set the
Number of Mice to X Number of Co.ck.roaches to Y; andNumber of Flies to Z.Note that the total money required for the snake's food is thus given as:
X + Y + Z = 100.................................A
5X + Y + 0.05Z = 100 .......................B
To remove the decimals in B, we multiply same both sides of the equation by 20 to get:
100X + 20Y + Z = 2,000 ........................C
Recall that the number of each animal purchased must ≥ 1
Since we are looking at the number of co.ck.roaches, let us set
X = 1
Z = 1
This gives us:
100 + 20Y + 1 = 2,000
Thus
20Y = 2,000-100-1
Y = 1899/20
Y = 94.95
Hence the answer is approximately 95 co.ckroaches.

The county fair charges 1.00 per ride and additional 3.00 to get in. Write an equation to represent the total cost of attending the fair
Final answer:
The total cost of attending the fair with an access fee and a per-ride charge is represented by the equation C = 3 + 1 × x, where x is the number of rides taken.
Explanation:
To calculate the total cost of attending the county fair which includes an access fee and a per-ride charge, we can write an equation where x represents the number of rides a person takes. The access fee is a fixed cost of $3.00, and the per-ride cost is $1.00. Therefore, if a person takes x rides, the total cost C can be represented by the equation:
C = 3 + 1 × x
For example, if the person takes 5 rides, we would calculate the total cost as 3 + 1 × 5 = $8.00.

How old am I if 400 reduced by 2 times my age is 244?
If 400 reduced by 2 times your age is 244, you will be 78 years old. This conclusion was reached by solving the equation 400 - 2x = 244, where x represents the unknown age.
Explanation:To solve the problem given, you need to work with the equation provided: 400 decreased by 2 times your age is 244. In mathematical terms, this can be written as 400 - 2x = 244, where 'x' represents your age.
Next, you need to solve for 'x'. The first step is to isolate 'x' by moving terms around. Add 2x to both sides to get 400 = 244 + 2x and then subtract 244 from both sides to get 156 = 2x. You finish the process by dividing both sides by 2, which gives you x = 78. Therefore, if 400 reduced by 2 times your age is 244, you are 78 years old.

The circumference of a circle is 65π. In terms of pi, what is the area of the circle?
A) 600 π
B) 936.5 π
C) 950.25 π
Eliminate
D) 1056.25 π
Final answer:
The area of the circle, given its circumference of 65π, is calculated as 1056.25π, using the formulas for circumference and area of the circle in terms of the radius.
Explanation:
The circumference of a circle is given by the formula 2πr where r is the radius of the circle. Given that the circumference is 65π, we can find the radius by rearranging the formula: r = circumference / (2π) = 65π / (2π) = 32.5. Next, we use the formula for the area of a circle, which is A = πr², substituting the value we found for r:
A = π(32.5)² = π(1056.25) = 1056.25π.
Therefore, in terms of π, the area of the circle is 1056.25π, which corresponds to choice D of the provided options.
