Answer:
3x =16 is the required equation.
Step-by-step explanation:
A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:
f(d) = 9(1.04)d
Part A: When the biologist concluded her study, the radius of the algae was approximately 12.81 mm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(d) represent? (2 points)
Part C: What is the average rate of change of the function f(d) from d = 3 to d = 9, and what does it represent?
Answer:
Step-by-step explanation:
Part A: A reasonable domain to plot the growth function would be from 0 to a reasonable maximum number of days, such as 30 or 60, depending on the duration of the study.
Part B: The y-intercept of the graph of the function f(d) represents the initial radius of the algae when d = 0, which would be 9 mm.
Part C: To find the average rate of change of the function f(d) from d = 3 to d = 9, we can calculate the difference in the function values at these two points and divide it by the difference in the input values. The average rate of change represents the average growth rate of the algae over that time period.

Answer: The answers are n+8=15, 15-8=n,and 15-n=8
Step-by-step explanation:
The reason why its those three is because if you solve them they equal 7 as the missing number but if you try 15+n=8 it doesnt make any sense.
how can I use A as a different variable.
When differing from X, Y and K
And when having 2x3= A
Even when I know A is a negative number.
You can use A as a different variable by simply assigning a value to it, like any other variable
What is a variable?A variable is a symbol used to denote a mathematical object in mathematics. Any number, vector, matrix, function, function argument, set, or set element can be represented by a variable.
An amount that can fluctuate depending on the mathematical issue is referred to as a variable. The generic letters x, y, and z are frequently employed in mathematical expressions and equations. A variable is, in other words, a symbol denoting a number whose value is unknown.
You can use A as a different variable by simply assigning a value to it, like any other variable. For example, you could write "A = -6" to assign the value of negative 6 to A. It's important to remember that A is now a distinct variable from X, Y, and K, and should be treated as such in your code or equations.

Frankie bought a new phone and bought some apps.
His phone has enough space for 50 apps.
1/5
of his apps were social media.
7/10
of his apps were games.
1/10
of his apps were educational.
How many of Frankie's apps are educational?
A 5
B 7
C 35
D 25
Answer: A(5)
Step-by-step explanation: First we need to convert 1/5 to 2/10 so we not work with the fractions. So 2/10 apps were social media and 7/10 were games so we can add those together to get 9/10. So 9/10 apps are not educational. We know 50÷10=5 so 5×9=45 so 45 apps are non-educational so that means 5 apps are educational.
Hope this helps!
1/5 of 50 = 10
7/10 of 50 = 35
1/10 of 50 = 5
there would be space for 5 educational apps <3

Step-by-step explanation:
We need to use the formula of area of a triangle to solve this. The formula is (1/2) * base * height. Here, the base is the distance from the line x = -4 to (2, 2), so the base is 6 units. The height is the difference from (-4, 4) and (-4, -3), which is 7 units. Thus, the area is (1/2) * 6 * 7 = 21 square units

Together, teammates Pedro and Ricky got 2685 base hits last season. Pedro had 281 more hits than Ricky. How many hits did each player have?
Answer:
1,483 is the answer
Answer:
Step-by-step explanation:
Let's say Pedro got x hits
and Ricky got y hits.Given,Pedro and Ricky together got 2685 hits.So, the
equation will be as (x+y)=2685................eq (1)
Given,Pedro had 281 more hits than Ricky.So the equation looks like
x=281+y..........eq(2).
substitute eq(2) in eq(1).We get,
2685=(281+y)+y
2685=281+2y
2685-281=2y
2404=2y
2404/2=y
y=1202
substitute y=1202 in eq(2).We get,
x=1202+281
x=1483
So,Pedro hit 1483 and Ricky hit 1202

At Pruitt’s farm, the ratio of oranges to apples is 4 to 8. A total of 96 apples and oranges are grown on his farm. Find the number of oranges grown.
A. 64
B. 32
C.12
D. 16
Answer:
32 (B)
Step-by-step explanation:
Because there is a total of 96 apples and oranges, you would divide 96 by 12 because 4 + 8 = 12. 96/12 is 8, so we know that each part (1 part of the ratio) would be 8. Since we are finding the number of oranges, you would multiply 4 x 8 which is 32. (B)

2.17 inches
10.68 inches
21.35 inches
36.29 inches
The required distance around the hat is approximately 21.35 inches. Option C is correct.
What is the circumference of the circle?To find the circumference of a circle, we use the formula C = πd, where C is the circumference, π is the mathematical constant pi (approximately equal to 3.14), and d is the diameter of the circle.
Here,
The distance around a circle is given by the formula circumference = π × diameter.
Substituting the given values, we get:
circumference = 3.14 × 6.8
circumference = 21.352
Rounding to the nearest hundredth, we get:
circumference ≈ 21.35 inches
Therefore, the distance around the hat is approximately 21.35 inches.

Help meeeeeeeeeeeeeee
Answer:
The error made in simplifying the expression is that 54 · 1 is supposed to be equivalent to 54, not 1.
Step-by-step explanation:
The Multiplication Property of One states that any number that is multiplied by one will stay the same, keeping its exact numerical value as before. However, in the expression shown, 54 multiplied 1 ended up equaling 1, which does not fit the Multiplication Property of One. Therefore, the error made in simplifying the expression is that 54 · 1 is supposed to equal 54, and not 1, based on the rule of multiplying any number by 1.

Does 6/10+8/100 = 14/10 or 68/10??
Answer:
The answer is 68/100 or 17/25
Step-by-step explanation:
To solve this problem, you need to find common denominators. In this equation, the easiest way to do this is to make both fractions have a denominator of 100. 8/100 is already in the proper denominator, and 6/10 can be multiplied by 10 to get 60/100. After adding, you get 68/100 which simplifies to 17/25
