In a lab experiment, 80 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 17 hours. How many bacteria would there be after 20 hours, to the nearest whole number?
Answer:
y = 181
Step-by-step explanation:
Doubling Formula:
[tex]y = a(2)^\frac{t}{d}[/tex]
y=80
d=17
t=20
plug in
y=80(2)[tex]^\frac{20}{17}[/tex]
y=180.818525349
y≈181

can someone please help me out with this problem ? i been trying to do this for like 2 days now and i still don’t get it .. also i need some tips on how i can remember this when im doing a different problem
Answer:
Step-by-step explanation:
the Pythagorean theorem is
c is the hypotenuse which is the side opposite of the right angle
plug the numbers into the Pythagorean theorem
[tex]x^2+(\sqrt{26})^2=13^2[/tex]
when squaring a square root, just take the number in the radical and get rid of the radical
[tex]x^2+26=169[/tex]
subtract 26 from both sides
[tex]x^2=[/tex][tex]143[/tex]
find the square root of 143
143 is prime so it can just be written as
[tex]x=\sqrt{143}[/tex]
Point D has coordinates (4, 1). What are the coordinates of Rx = 2(D)?
Answer:
The coordinates of Rₓ = [tex]2^{(D)}[/tex] = D'(0, 1)
Step-by-step explanation:
As given, D = (4, 1)
Now,
The coordinates of Rₓ = [tex]2^{(D)}[/tex] = D'(0, 1)
Which type of triangle has side measures of 5 cm, 9 cm, and 12.7 cm and one angle measure of 128°?
A.
acute isosceles
B.
obtuse scalene
C.
obtuse isosceles
D.
acute scalene
This question is dealing with classification of triangles based on angles or on number of equal sides.
the triangle is called an Obtuse Scalene Triangle
Now, the classification in terms of angles are;
- Acute angle is when the angle measures between 0 and 90 degrees.
- Obtuse angle is when the angle is greater than 90 but less than 180 degrees.
- right angle is when the angle is exactly 90 degrees.
- Reflex angle is when the angle is greater than 180 but less than 360 degrees.
Now the classification in terms of equal sides;
- Isosceles triangle is one that has 2 equal sides.
- Equilateral triangle is one that has 3 equal sides.
- Scalene triangle is one that has no equal sides.
The lengths of the three sides of the triangle given are;
5 cm, 9 cm, and 12.7 cm
The three sides are not equal and from definition above it is called scalene triangle.
The angle given is 128° and from definition earlier, it is an obtuse angle.
In conclusion, the triangle is called an Obtuse Scalene Triangle

William has a sticker album. Some pages have 1 sticker on them, and other pages have 2 stickers on them. If William has 18 stickers, how many different ways can he put the stickers in the album?
Answer:
6 ways
Step-by-step explanation:
William has a sticker album.
We are told in the question that:
Some pages have 1 sticker on them, and other pages have 2 stickers on them. If William has 18 stickers
The many different ways that can he put the stickers in the album is calculated as:
18 stickers ÷ ( 1 stickers + 2 stickers)
= 18 ÷ 3
= 6 ways
Therefore, the different ways that he can put the stickers in the album is 6 ways
6^2 – 7(8 + 6. – 3^2)
The value of the expression is

Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account which inequality shows the number of months it would take Brad to save at least $200
The inequality representing the problem will be x+3 ≥ 8
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account, and saves at least $200.
Let the number of months be x,
75 + 25x ≥ 200
25(3+x) ≥ 200
x+3 ≥ 8
Hence, The inequality is x+3 ≥ 8
