Are the two fractions proportional? 6/8 and 24/28
Answer:
no
Step-by-step explanation:
for them to be proportional they would be equal when simplified
if we simplify both
6/8=3/4 (divide by 2)
24/28=6/7 (divide by 4)
they are not the same therefore not proportional

Write an equation (any form) for the quadratic graphed below
Answer:
[tex]-\frac{1}{2} (x - 1)^2 + 1[/tex]
Explanation:
Since it is flipped and now extending to negative infinity, we make [tex]x^2[/tex] negative, so it is [tex]-x^2[/tex].
Lastly, there are a few shifts, it is shifted right once and up once.
To shift it right once, you would subtract a 1 from x directly: [tex]-(x - 1)^2[/tex]
To shift it up once, you would add 1 to the entire equation: [tex]-(x - 1)^2 + 1[/tex]
To account for the stretching, it would be: [tex]-\frac{1}{2} (x - 1)^2 + 1[/tex]

How can you use mental math to find the produce 6 x 295?
Answer:
Break up the number
Step-by-step explanation:
6 x 295 = 1770
295 = 200 + 90 + 5
(6 x 200) + (6 x 90) + (6 x 5) = 1770
1200 + 540 + 30
1740 + 30
1770
The value of the expression 6 x 295 using the property of multiplication will be 1770.
What is Algebra?Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to answer the problem correctly and correctly.

Since the tenths place in .079 has a zero and tenths place in .12 has a 1, .12 would be larger.
A population of a particular yeast cell develops with a constant relative growth rate of 0.4225 per hour. The initial population consists of 3.9 million cells. Find the population size (in millions of cells) after 3 hours. (Round your answer to one decimal place.)
Answer: The population after 3 hours is 13.9 mill.
Step-by-step explanation:
When we have an exponential with:
A = initial population.
r = constant relative growth rate:
t = time.
The function that models this is:
P(t) = A*e^(k*t)
In this case we know that:
A = 3.9 mill.
r = 0.4225 1.
Then the function that models the population of this yeast cell is:
P(t) = (3.9 mill)*e^(0.4225*t)
where t represents the time in hours.
Then if we want to know the population after 3 hours, we should replace t by 3.
P(3) = (3.9 mill)*e^(0.4225*3) = 13.85 mill.
And we want to round our answer to one decimal place, then we must look at the second decimal place, we can see that is a 5, so we should round up.
The population after 3 hours is 13.9 mill.
The exponential function is often used to model the growth or decay of a population
The population size of the yeast cell after 3 hours is 7.9 million
The given parameters are:
[tex]\mathbf{a = 3.9m}[/tex] --- initial number of cells
[tex]\mathbf{r = 0.4225/hr}[/tex] --- rate
The nth term of an exponential function is:
[tex]\mathbf{f(n) = a(1 + r)^{n-1}}[/tex]
After 3 hours; n = 3
So, we have:
[tex]\mathbf{f(3) = a(1 + r)^{3-1}}[/tex]
Substitute values for a and r
[tex]\mathbf{f(3) = 3.9(1 + 0.4225)^{3-1}}[/tex]
[tex]\mathbf{f(3) = 3.9(1 + 0.4225)^{2}}[/tex]
[tex]\mathbf{f(3) = 3.9 \times (1.4225)^{2}}[/tex]
[tex]\mathbf{f(3) = 7.9}[/tex]
Hence, the population size of the yeast cell after 3 hours is 7.9 million

1. The value of 25 x (8.5) is:
a.
More than 250
b. Less than 250
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The value of 25×8.5 is less than 250. The correct option is B.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The value of 25×8.5 is needed to be calculated in order to know if the product is more than 250 or not. Therefore, the value of the 25×8.5 can be calculated as,
25×8.5
= 25 × (85/10)
= 2125/10
= 212.5
Since the value of the product of 25 and 8.5 is 212.5 which is less than 250. It can be calculated that the number is smaller than 250.
Hence, the value of 25×8.5 is less than 250.
