part c and b arent clear but the answer to a is this:
if you want to find 40% of something, start with finding 10% then multiplying by 4 to get 40%. 10% of 24.99 is 2.49. 2.49 times four is 9.96. so thats 40% of 24.99.
to find the price, subtract 9.96 from 24.99.
you get $15.03
The right answer choice is the option "A. A type of growth that is exponential at first but slows as the amount reaches a certain maximum value".
Karan swam and biked for a total of 1 hour and 45 minutes.
let's say 60=100 for a total of 100 equaling 1 hour.
Therefore, 100+45= <u>145</u>
Answer:
(n + 4)(n+ 22)
Step-by-step explanation:
One way to determine which factored expression is accurate is by asking the question: "Which two numbers multiply to 88, but add to 26?" If you are having difficulty using this method, you can always try the guess-and-check method with a multiple choice question. This way involves multiplying the terms inside one set of parentheses with the terms inside the other set of parentheses.
Step #1: Multiply the first terms
(n + 4)(n + 22) ----> n x n = n²
Step #2: Multiply the inside terms
(n + 4)(n + 22) -----> 4 x n = 4n
Step #3: Multiply the outside terms
(n + 4)(n + 22) -----> n x 22 = 22n
Step #4: Multiply the last terms
(n + 4)(n + 22) -----> 4 x 22 = 88
Step #5: Write the new expanded equation and simplify
(n + 4)(n + 22) -----> n² + 4n + 22n + 88 -----> n² + 26n + 88
Answer: y=-9/4x+21
Step-by-step explanation:
To find a line that passes through the given points, we can use them to find the slope. Once we have the slope, we can plug in any point and solve for the y-intercept. The formula to solve for slope is .
Now that we have the slope, we can plug in any point.
12=-9/4(4)+b [multiply]
12=-9+b [add both sides by 9]
b=21
Now that we know the y-intercept, the equation is y=-9/4x+21.
