It takes 21 minutes for a certain population of bacteria to double. If there are approximately 8,014,000 bacteria in this population at 10 a.M., what is the best estimate, in millions, of the number of bacteria at 10:42 a.M. On the same day?
Answer:
32 million
Step-by-step explanation:
Given that:
Time it takes population to double = 21 minutes
Number of bacteria at 10a.m = 8,014,000
Best estimate of bacteria at 10:42
Difference :
10:42 - 10:00 = 42 minutes
42/ 21 = 2 times
Hence it doubles 2 times within the time range :
At 10:21 minutes :
8,014,000 * 2 = 16,028,000
At 10:42 minutes :
16,028,000 * 2 = 32,056,000
Best estimate is 32 million

Graph the line with the equation y = 1/5x-2.
3 4 5 6 7 8 9 10
Answer:
graph as seen below :)
Step-by-step explanation:
when graphing an algebraic equation, it is important to remember mx+b and what it stands for. m is the variable used to describe the slope and when in the form of a fraction is rise over run/vertical over horizontal/up over side/etc. so for this one, start at the y-intercept (0,-2) and go up 1, over 5, then plot that point. then continue the pattern for you graph and do the same backwards so you go down 1 and to the left 5. x is the variable that normally stays a variable in the equation. and finally, b is the y-intercept, so when the line passes through a point where x = 0 (that part is normally confusing form me cuz its the y-intercept so just think of it as when the point is on the y axis). then, you can plot points to make the graph shown below. sorry the graph is kinda trash but you can see that when you go over 5 you go up one.
if you have any questions make sure to comment so that i can clarify anything thats a little silly or confuzzling :)

A satellite dish is the shape of a paraboloid. The dish is 30
inches wide, and 10 inches deep. How many inches should
the receiver be located from the vertex for optimal reception?
(round to the nearest thousandth)
Receiver •
Answer:
The receiver should be located at (0, 5.625)
Step-by-step explanation:
The given parameters are;
The width of the satellite dish = 30 inches
The depth of the dish = 10 inches
The receiver should be located at the focus of the parabola
Where the vertex of a parabola is (0, 0)
The equation of an upward or downward facing parabola is x² = 4·p·y
The focus of the parabola = (0, p)
The directrix is given by y = -p
The axis is the x-axis
Therefore, given that the width = 30 inches and the depth = 30 inches, we have;
The points (-15, 10), (15, 10), and (0, 0) (which is the vertex) on the parabola
Substituting, the coordinates into the equation of the parabola gives;
(-15)² = 4 × p × 10
p = (-15)²/(4 × 10) = 5.625
The coordinate of the focus = (0, 5.625)
Therefore, the receiver should be located at (0, 5.625).
The distance that the receiver should be located from the vertex to receive optimal reception is;
5.625 inches above the vertex
We are given;
Width of the satellite dish = 30 inches
Depth of the satellite dish = 10 inches
Vertex of parabola is at (0, 0)
If we imagine a parabola that has its vertex located at the origin, the symmetry of the parabola will make us know that the depth is the height which in this case is 10 inches while the edge is 15 inches (1/2 of 30 inches) to both right and left sides of the axis of symmetry.
Thus, we can say that this parabola passes through the point (15, 10).
Now, the conic form of a parabola with its vertex at the origin is given by the formula; y = (1/4c)x²
where c is the distance between the focus and the vertex.
Plugging in the relevant values gives;
10 = (1/4c)(15)²
4c = 225/10
4c = 22.5
c = 22.5/4
c = 5.625
Thus, the receiver should be located at 5.625 inches above the vertex so for optimal reception.

A new health drink has 180% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 40 mg. How many milligrams of the vitamin are in the drink?
Answer:
72 mg of vitamin are in the drink
Step-by-step explanation:
The drink has 180% of the RDA
And the RDA is 40 mg
The number of milligrams present in the drink will be;
180% of 40 mg
= 180/100 * 40 = 180/2.5 = 72g
You have a coupon for 10% off your total. You bill comes to $59.12. How much is your bill after you use the coupon?
Answer:
$53.21
Step-by-step explanation:
If 10% comes off of the 100% that we would have paid originally, that means we're just paying 90%. That means we've to calculate:
$59.12 * 90% =
$59.12 * .9 =
$53.208.
Because you don't really pay anything past the hundredths place, we can just round the 8 up to get: $53.21
Answer:
$53.21
Step-by-step explanation:
You have a 10% discount so .10 times your total is the discount:
.10 x 59.12 = 5.912
Now, subtract $5.91 from the the total to get the price after a coupon (rounded to 5.91 because cents don't go into the thousandths place):
$59.12 - $5.91
= $53.21
So, your bill is $53.21 after the coupon is used

Neko made a triangular flag shown below. He wanted to attach it to the stick and then trim off the extra fabric so the flag would form an
isosceles triangle. By how many degrees was he off when he attached the triangle to the stick?
Answer:
Pretty sure its A
Step-by-step explanation:
Neko's flag ended with a triangle having 62 and 86 degrees as base angles because the stick was 12 degrees out of alignment from the proper position (both angles are 74 degrees each) - Option A
Recall:
Isosceles triangle is a triangle having two congruent base angles and two equal sides.Thus:
In the base angles of the triangle formed by the flag with the stick are as follows:
180 - 118 = 62 degrees (linear pair)
180 - (62 + 32) = 86 degrees. (sum of triangles)
Neko ended up having a flag that has 62 and 86 degrees base angles.
For both angles to be equal, we would have the following:
62 + 12 = 74 degrees86 - 12 = 74 degreesIn conclusion, Neko's flag ended with a triangle having 62 and 86 degrees as base angles because the stick was 12 degrees out of alignment from the proper position (both angles are 74 degrees each) - Option A

Step-by-step explanation:
If y is directly proportional to x
y = kx
k is the constant of proportionality
k = y/x
From the allocated point
y = 3 and x = 1
k = 3/1 = 3
Identify the constant of proportionality.
y=22x
Answer:
11
Step-by-step explanation:
The constant of proportionality is 22.
What is Constant of proportionality?The proportionality constant is the constant value of the ratio of two proportional quantities. When the ratio or product of two changing quantities generates a constant, they are said to be in a proportionate relationship. The proportionality constant's value is determined by the type of proportion between the two specified quantities: direct variation or inverse variation.
We have the equation is
y = 22 x
As, we know that from direct proportion as
y α x
y= k x

Write a number that makes this equation true. 4\text{ hundreds} =4 hundreds=4, start text, space, h, u, n, d, r, e, d, s, end text, equals \text{ones}onesstart text, o, n, e, s, end text
Answer:
hundreds = 1, for the equation to be true.
Step-by-step explanation:
Given an equation:
[tex]\frac{4}{hundreds}[/tex] = 4 hundreds = 4
For this equation to be true, hundreds should be represented by a minimum value.
This implies that, hundreds can not be represented by a number which equal zero, less than or greater than 1. Therefore, hundreds = 1.
So that;
[tex]\frac{4}{1}[/tex] = 4 x 1 = 4
⇒ 4 = 4 = 4
Thus, a true expression.
For the given equation to be true, hundreds must be equal to 1.
E.g: [tex]\frac{100}{hundreds}[/tex] = 100 hundreds = 100
For this equation to be true, hundreds = 1.
So that;
[tex]\frac{100}{1}[/tex] = 100 x 1 = 100
⇒ 100 = 100 = 100
