A colony of 300,000 bacteria doubles in size every 35 minutes what will the population be 70 minutes from now ?
Answer:
1,200,000
Step-by-step explanation:
300,000 x 4
It doubles every 35 minutes so you multiply by 4
Answer:
X=600000
Step-by-step explanation:
Let the unknown value for 70minutes be x
So let's solve the given question
300000 bacteria is double in every 35minutes
So to solve we will have
300000 bacteria=35minutes
X bacteria=70 minutes
So let's cross multiply
35x=300000×70
Let's make x the subject of formula by dividing both sides by 35
X=300000×70/35
X=300000×2
X=600000
Therefore the population in 70 minutes is 600000

Find the area of the complex figure.
Not drawn to scale.
Answer:
1863 [tex]meters^{2}[/tex]
Step-by-step explanation:
( 23 x 12 ) x 2 = 552
69 x 19 = 1311
1311
+552
= 1863 [tex]meters^{2}[/tex]
The area of the complex figure is 1,863 square meters
To find the area of the complex figure, break it down into individual rectangles and then sum up their areas. The complex figure consists of two smaller rectangles and one larger rectangle.
For the first two rectangles:
- Length = 23 m
- Width = 12 m
The area of each of the first two rectangles is:
Area = Length × Width = 23 m × 12 m = 276 square meters
Now, for the larger rectangle:
- Length = 69 m
- Width = 19 m
The area of the larger rectangle is:
Area = Length × Width = 69 m × 19 m = 1,311 square meters
To find the total area of the complex figure, sum up the areas of the three rectangles:
Total Area = Area of the first two rectangles + Area of the larger rectangle
Total Area = (276 square meters + 276 square meters) + 1,311 square meters
Total Area = 552 square meters + 1,311 square meters
Total Area = 1,863 square meters
So, the area of the complex figure is 1,863 square meters. This approach demonstrates how to find the area by breaking down the complex figure into simpler shapes and summing their individual areas.

The length of a rectangle is 3 centimeters less than twice the width. If the perimeter of the rectangle is 24 centimeters, find its dimensions.
Answer:
Width = 5 cm
Length = 7 cm
Step-by-step explanation:
Width = w
Length = 2w - 3
Perimeter = 24 cm
2* (length + width ) = 24
2*(2w-3 +w) = 24
2*(3w -3) = 24
3w - 3 = 24/2
3w - 3 = 12
3w = 12+ 3
3w = 15
w = 15/3
w = 5cm
Length = 2w - 3 = 2*5 - 3 = 10-3 = 7 cm
length = 7 cm
Kay is drawing a triangle. Two of the sides have an equal length of 8 cm, and the angle between those sides measures 68°. Which could be the measure of each base angle?
The measure of each base angle is 56°.
Step-by-step explanation:
The isosceles triangle has two base angles that are congruent (same measure).Let the measure of each base angle is 'x'.The sum of angles in a triangle add to 180°.base angle + base angle + 68° = 180°
2x + 68° = 180°
2x = 112°
x = 112/2
x = 56°
Therefore, the measure of each base angle is 56°.
The required measure of each base angle is equal to 56°.
It involves understanding the properties of an isosceles triangle, which is the key to solving the problem. In an isosceles triangle, if two sides are equal, the angles opposite those sides are also equal.
Given that Kay is drawing a triangle with two equal sides of 8 cm and the angle between these sides measures 68°, the triangle is isosceles, and we know that the other two angles (the base angles) are equal due to this property.
The sum of all angles in any triangle equals 180°. Therefore, to find the measure of each base angle, we subtract the given angle from 180° and then divide by 2 (since the base angles are equal):
The sum of angles in a triangle = 180°.
The measure of the angle between the two sides = 68°.
The sum of the two base angles = 180° - 68° = 112°.
Measure of each base angle = 112° / 2 = 56°.
Therefore, the measure of each base angle in Kay's triangle is 56°.

Side of the square = 4 units
Area of the square = 4 * 4 = 16 units
2. What is the total value?
Difference of eleven and nine divided by two = (11 - 9)/2

The correct answer is D. 17
The combined result of the area of a square with a side of four units and the arithmetic expression (11 minus 9) divided by 2 is 17.
Explanation:Calculating the Combined Area and Arithmetic Expression
To solve the given problem, we need to calculate the area of a square with a side of four units and add this to the arithmetic expression (11 minus 9) divided by 2. First, let's find the area of the square. The area of a square is found using the formula area = side × side. Therefore, the area of our square is 4 units × 4 units = 16 square units.
Next, we calculate the arithmetic expression. The difference of eleven and nine is 11 - 9 = 2, and dividing this by two gives us 2 / 2 = 1.
Finally, we add the area of the square to this result: 16 square units + 1 = 17. The final answer is 17.
16 m, 21 m, 39 m in geometry tryna find out how to measure the side length that could form a triangle
Step-by-step explanation:
The given measurements are:
16 m, 21 m, 39 m
We know that, it is only possible to form a triangle if sum of the measures of any two lengths is always grater than the measure of third length.
[tex] \therefore \: 39 + 21 = 60 > 16 \\ \\ \: \: \: \: \: \: 16 + 39 = 55 > 21 \\ \\ \: \: \: \: \: \: 16 + 21 = 37 \ngtr39 \\ \\ \because \: last \: mathematical\: statement \: is \:\\ defying \: the \: above \: law \\ [/tex]
Therefore, it is not possible to form a triangle with given measurements.
The given lengths cannot form the sides of a triangle because they dont satisfy the sides of a triangle rule.
What is the sides of a triangle rule say?The sides of a triangle rule asserts that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side.
Given here, are the sides 16 m, 21 m , 39m
now if the two sides are 16, 21 then their sum is 16+21 = 37 but 37<39 thus combination of lengths cannot form a triangle
Hence, the lengths 16,21,39 cannot form the sides of a triangle

Each of the letters of the word ALABAMA are written on a piece of paper and then put into a bag. A piece of paper is drawn at random. What is the theoretical probability, as a decimal, of drawing an A? Round the decimal to the nearest hundredth.
The theoretical probability of drawing an 'A' from the word 'ALABAMA' is 0.57. This result arrives from dividing the number of 'A's (4) by the total number of letters in 'ALABAMA' (7).
Explanation:The question deals with a probability problem related to the selection of letters from the word 'ALABAMA'. The word 'ALABAMA' has 7 letters out of which 4 are 'A's. The theoretical probability is calculated as the number of successful outcomes divided by the total number of outcomes. Since we are interested in drawing an 'A', the successful outcomes are the number of 'A's which is 4, and the total outcomes are the total number of letters which is 7.
To calculate theoretical probability, you divide the number of successful outcomes by the total number of outcomes. In this case, the calculation will be 4 / 7 = 0.57 (rounded to the nearest hundredth).
So, the theoretical probability of drawing an A from the word 'ALABAMA' in decimal form, rounded to the nearest hundredth, is 0.57.

Solve this system of linear equations: 4x-2y=8 Y=3/2x-2
The solution to the system of equations is x = 4 and Y = 4.
Explanation:To solve the system of linear equations, we can use substitution. Since we have the equation Y = 3/2x - 2, we can substitute this expression for Y in the first equation.
Substituting Y = 3/2x - 2 in 4x - 2y = 8:
4x - 2(3/2x - 2) = 8
Simplifying the expression:
4x - 3x + 4 = 8
x + 4 = 8
Solving for x:
x = 8 - 4
x = 4
Substituting the value of x into Y = 3/2x - 2:
Y = 3/2(4) - 2
Y = 6 - 2
Y = 4
Therefore, the solution to the system of equations is x = 4 and Y = 4.

To solve for any variable (N in this case) you must get it by itself, by doing the opposite operation. To do so for this problem, divide 23 from both sides. In doing so, N will be by itself, and you'd then just divide 23 from 8.05. Thus getting 0.35 as an answer.
I hope this helps!
