Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000143 mm, while the length of the second strain measures 0.0000000937 mm. How much larger is the first strain than the second?

Answers

Answer:

1.53 times

Step-by-step explanation:

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000143 mm, while the length of the second strain measures 0.0000000937 mm. How much larger is the first strain than the second?

We would have:

First strain : Second strain

0.000000143 mm : 0.0000000937 mm

How much larger is the first strain than the second?

We divide both by the length of the second strain

0.000000143/0.0000000937 : 0.0000000937 / 0.0000000937

Figuring out ratios is pretty simple. Example: If the ratio of soccer balls to baseballs is 3:1 that means there are 3 soccer balls for every 1 baseball. Notice how it says “soccer balls to baseballs” and “3:1” the first type of ball/object is the subject for the 3 and the second ball/object is the number for the 1. So when it asks the ratio of chocolate cookies to the whole box, you need to put the number of chocolate cookies first (25) and the cookies in the whole box (40). So now the ratio is 25:40. Simplify and make it into fraction form and the answer is 5/8.

On a coordinate plane, point B(–6, 1) is translated to B prime(–3, –2). Indira uses these steps to find a rule to describe the translation.

Step 1 Substitute the original coordinates and the translated coordinates into (x, y) right-arrow (x + a, y + b):

B (negative 6, 1) right-arrow B prime (negative 6 + a, 1 + b) = B prime (negative 3, negative 2)

Step 2
Write two equations:
Negative 6 + a = negative 2. 1 + b = negative 3.

Step 3
Solve each equation:
Negative 6 + a = negative 2. a = negative 2 + 6. a = 4. 1 + b = 3. b = negative 3 minus 1. b = negative 4.

Step 4
Write the translation rule:
(x, y) right-arrow (x + 4, y minus 4)

Which corrects Indira’s first error?
Indira should have substituted B (negative 6, 1) right-arrow B prime (negative 3 + a, negative 2 + b) = B prime (negative 6, 1) in Step 1.
Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.
Indira should have solved the equations to find that a = negative 8 and b = negative 2 in Step 3.
Indira should have written the translation rule (x, y) right-arrow (x minus 4, y + 4) in Step 4.

Answer:

137 [tex]ft^2[/tex]

Step-by-step explanation:

1. Approach

Break up the given figure into smaller figures. One can break up this figure into a rectangle, and a triangle. After doing so, one can calculate the area of each of the smaller figures, and then add up the values.

2. Calculate the area of the triangle

If one were to cut the top figure off, one would get a triangle with a base of (3ft), and a height of (6ft). One can calculate the area of the figure using the formula;

[tex]\frac{base*height}{2}[/tex]

Substitute;

[tex]\frac{6*3}{2}\\\\= \frac{18}{2}\\\\\ 9[/tex]

3. Calculate the area of the rectangle;

Now, one is left with a rectangle with dimensions (16ft), and (8ft). To find the area of this figure, use the formula;

[tex]base * height[/tex]

Substitute;

[tex]16 * 8\\\\= 128[/tex]

4. Find the area of the whole figure

Now add the area of the triangle, and the area of the rectangle together.

(Rectangle) + (Triangle)

= 128 + 9

= 137
