The answer is 37!
(-8)^2 - 5(-8) + 7 = 111
(111)(1/3) = 37
Answer:
Step-by-step explanation:
volume = 180 * 9
volume = 1620 in³
Answer:
11.25cm^2
Step-by-step explanation:
given the area of the rectangle as 40cm^2, we can get the width of the rectangle.
Area =Length x width
40cm^2 = 8cm x width
we can divide both sides 8 to be left with the width
40/8 = 5cm
so the width is 5cm which is equal to the height of the triangle.
Area of BDC = 1/2 x base x height
BDC = 1/2 x 4.5 x 5
=11.25cm^2
The half-life of the given exponential function is of 346.57 years.
<h3>What is the half-life of an exponential function?</h3>
It is the value of t when A(t) = 0.5A(0).
In this problem, the equation is:
.
In which t is measured in years.
Hence the half-life is found as follows:
t = 346.57 years.

#SPJ1
Let x = number of students enrolled in both Science and Arts.
Then the number of students taking Science only is 17 – x and,
the number of students taking Arts only is 19 – x.
We know that
Total # of students in class = # Science only + # Arts only + Both Arts & Sciences + # Any
= (17 – x) + (19 – x) + x + 2
= 38 + x
This should be equal to 30 as given. So,
38 – x = 30
Subtract 38 from both sides:
–x = –8
So x = 8.
Answer: 8
