Answer:
There are 147 students in the school.
Step-by-step explanation:
3/7 of the students are in sixth grade, 63 students are in the sixth grade.
take 63 and divide it by the numerator, 3, you get 21.
You now multiply the fraction by 21 to get the full number of students in the school.
3 * 21 = 63, 7 * 21 = 147
So 63 sixth graders out of 147 total students in the school.

Evaluate the function for an input value of 3. f(x)= −4x 2 −3x−5
Answer:
- 50
Step-by-step explanation:
x = 3
f ( x ) = - 4x^2 - 3x - 5
f ( 3 )
= - 4 ( 3 )^2 - 3 ( 3 ) - 5
= - 4 ( 9 ) - 3 ( 3 ) - 5
= - 36 - 9 - 5
= - 50

Answer:
[tex]\huge\boxed{\boxed{12a-60}}[/tex]
Step-by-step explanation:
Hello.
The Distributive Property states that
a(b+c)=ab+ac
Where
a, b, and c can be either constants or variables
we distribute a by multiplying it times b and c, and simplify if necessary.
In this case, we should distribute 12:
12(a-5)
12 times a and 12 times (-5):
12a-60
And we're done!
I hope it helps & have an outstanding day!

The lenght of a turtles shell z, in millimeters, is related to the turtles age in years a , as described by the equation below.
s=55a+37
Which statements about the turtle are true?
Select 3
Answer:
B, C , F
Step-by-step explanation:
The age multiplied 55, so the shell grows at rate of 55mm per year
in fact if the age is 2 we have (55 x 2) = 55 + 55
if 3 = (55 x 3) = 55 + 55 + 55
and so on
When the turtle is hatched the shell is 37 mm in lenght.
In fact, if we substitute 0 to a, we have
s = (55 x 0) + 37
s = 37
when the turtle is 1 year old, the shell is 92 mm in length.
in fact if we substitu a with 1, we have
s = (55 x 1) + 37
s = 55 + 37
s = 92

On her 21st birthday, Sydney deposited $400 in a new bank account that earns 3.7% interest compounded continuously. If there are no other deposits or withdrawals, how much interest will she have earned by her 60th birthday
Answer:
$1,649.80
Step-by-step explanation:
Sydney will have earned $1293.35 in interest by her 60th birthday.
How to find interest?To solve this problem, we need to use the formula for continuously compounded interest:
A = P [tex]e^{rt}[/tex]
Where:
A is the final amount of money in the account (including principal and interest)
P is the initial principal (in this case, $400)
r is the interest rate (in this case, 3.7% per year)
t is the number of years the money is invested (in this case, 39 years)
e is the mathematical constant approximately equal to 2.718
Plugging in the values from the problem, we get:
A = $400[tex]e^{0.037 \times 39}[/tex]
Calculating this, we find that A = $400[tex]e^{1.443}[/tex] = $1693.35
Therefore, he will have earned $1693.35 - $400 = $1293.35 in interest by her 60th birthday.
