Answer:
the size of the bacterial population after 100 minutes is 20,158.7 bacteria
the size of the bacterial population after 10 hours is 2097152000 bacteria
Step-by-step explanation:
Given that
The bacteria contains 2000
It would be double at every half hour
We need to find out the size of the bacteria after 100 minutes & 10 hours
So,
The size of the bacteria after 100 minutes is
= 2000 × 2^(100 ÷ 30)
= 2000 × 10.079
= 20,158.7 bacteria
Now the size of the bacteria after 10 hours is
10 hours = 10 × 60 minutes = 600 minutes
= 2000 × 2^(600 ÷ 30)
= 2097152000 bacteria

Answer:
60 degrees
Step-by-step explanation:
This is an equilateral triangle. Each angle has the same measure. There are three angles. So: 180 ÷ 3 = 60.
Answer:
60
Step-by-step explanation:
The figure shown is a triangle
To be more specific an equilateral triangle.
We know that this is an equilateral triangle because all of the side lengths are congruent ( indicated by the little mark on each side ) and if each side length is congruent then each angle is congruent.
Because the sum of the angles in a triangle adds up to equal 180 we can simply find the measure of each angle by dividing 180 by 3
180/3=60
so every angle = 60 degrees
Therefore your answer is 60

find the value of x
−8(x−6)=32
Answer:
x = 2
Step-by-step explanation:
-8(x-6) = 32 (distribute)
-8x+48 = 32 (subtract 48 from both sides)
-8x = -16 (divide)
x = 2
Answer:
x = 2
Step-by-step explanation:
Divide both sides :
−8(x−6)=32
Divide both sides of the eqaution by -8 :
x - 6 = -4
Move the constant to the right :
x - 6 = -4
Move the constant to the right - hand side and change its sign :
x = -4 + 6
Calculate :
x = -4 + 6
Calculate the sum :
x = 2
Therefore, the answer is x = 2

Kendra is determining the distance between the points (6, 8) and (2, –3). Her work is shown below.
Step 1: d = StartRoot (6 minus 2) squared + (8 minus 3) squared EndRoot
Step 2: d = StartRoot (4) squared + (5) squared EndRoot
Step 3: d = StartRoot 16 + 25 EndRoot
Step 4: d = StartRoot 41 EndRoot
Which best describes the accuracy of Kendra’s solution?
Her solution is correct.
Her solution is incorrect. She subtracted before squaring.
Her solution is incorrect. She made an error when substituting the x-values into the equation.
Her solution is incorrect. She made an error when substituting the y-values into the equation.
Answer:
Her solution is correct

Two sides of a triangle have length 10 and 17. What is the range of the length of the 3rd side
Answer:
13.7477270849 to 19.7230829233.
Step-by-step explanation:
1. Using the pythagorean theorem, a²+b²=c², we try different combinations of given lengths 10 and 17.
2. If 10 and 17 are legs and 10²+17²=√389 = 19.7230829233, then c=19.7230829233.
3. If 10 is a leg and 17 is a hypotenuse,
10²+b²=17²
100+b²=289
b²=189
b=13.7477270849
4. The case of 17 is a leg and 10 is a hypotenuse is not possible because the hypotenuse is the longest side.
5. The range of the length of the 3rd side is 13.7477270849 to 19.7230829233.
Pablo grew a plant for school and recorded the growth of the plant
each week. He wrote ordered pairs to organize his data: (1, 5), (2, 8),
(3, 8), (4, 11), (5, 15).
Is this relation a function? Explain.
Answer:
Yes. the relation is a function
Step-by-step explanation:
Here, we want to check if the relation is a function
if a relation is a function, then every x-values (input values) will have one y-value
No two output values (y values) will have a single x value
Looking at the pairs;
It is a function
Although two x values have same y value; 2 and 3 to 8; no two y values have same x value
Hence, the ordered pairs is a function

a) The mean is _____. *
b) The standard deviation is _____. *
c) Approximately _____ % of the data values fall between 223 and 237. *
This is a required question
d) Approximately _____ % of the data values fall between 216 and 244.
e) Approximately _____ % of the data values fall between 209 and 251.
Answer:
If all of the observed values in a sample are close to the sample mean, the standard deviation will be small (i.e., close to zero), and if the observed values vary widely around the sample mean, the standard deviation will be large. If all of the values in the sample are identical, the sample standard deviation will be zero.

The scale of map is 1cm : 70km. What is the actual distance between towns that are 5cm apart on the map
Answer: 350km
Step-by-step explanation:
Since we are informed that the scale of map is 1cm : 70km. Therefore, the actual distance between towns that are 5cm apart on the map will be:
= 5 × 70km
= 350km
Therefore, the answer is 350km

Q1.) A carton contains 25 cards numbered 1 to 25. Alecia picks a card randomly. What is the probability that Alecia will pick an odd number?
Answer:
52%
Step-by-step explanation:
Since there are 25 numbers in 1-25, you need to divide 100/25 which is 4.
There are 13 odd numbers in 1-25 so you need to multiply 13x4.
13x4=52
There is a 52% chance she will pick an odd number.
Suppose a geometric sequence has a common ratio of 5. What is the next term after 9?
Answer:
45Step-by-step explanation:
[tex]a_{n+1}=a_n\cdot r[/tex]
So, if the common ratio is 5 the next term is always 5 times the previous term.
9·5 = 45Write the equation of the line that is parallel to the line -3x+2y=10 and goes through the point (4,7).
Answer:
y=-3/2x+13
Step-by-step explanation:
Convert to slope-intercept form (y=mx+b):
-3x+2y=10
-3x-10+2y=0
-3x-10=-2y
-3/2x-5=y
y=-3/2x-5
Parallel lines have the same slope, so the slope of the equation will be m₁=m₂ where -3/2=-3/2
Solving for b, the y-intercept, we get:
y=-3/2x+b (Equation so far)
7=-3/2(4)+b [Plugging in (4,7)]
7=-12/2+b
7=-6+b
13=b
Therefore, the equation of the line that is parallel to the line -3x+2y=10 and goes through the point (4,7) is y=-3/2x+13
What is the slope of line b?

when a car speed is 24 km/hr a journey takes 80 minutes what must the speed be for the same journey to take 60 minutes?
Answer:
32 km/ hr
Step-by-step explanation:
Given that :
Speed of car = 24km/ hr
Time taken =. 80 minutes = 80 / 60 = 1.33333 hours
The distance traveled :
Speed * time
24 km/hr * 1.333333 = 32 km
Speed required to complete 32 km. Journey in 60 minutes = 1 hour
Speed = distance / time
Speed = 32 km / 1 hour
Speed = 32 km/ hr
