Answer:

Answer:

The difference between the size of white blood cells and the size of red blood cells in scientific notation is 5.5 * 10^(-6) m.

Step-by-step explanation:

we are given that the size of white blood cells is 0.000012 metres and the size of red blood cells is 0.0000065 metres.

And we have to find the difference between the size of both cells in scientific notation.

SO, Size of White blood cells = 0.000012 m

      Size of Red blood cells = 0.0000065 m

Now, Difference between both cell sizes = Size of white blood cells - Size of Red blood cells

                           =  0.000012 m - 0.0000065 m

                           =  0.0000055 m

Now, in scientific notation it is represented as =  5.5 * 10^(-6) m

Hence, the difference between the size of white blood cells and the size of red blood cells in scientific notation is 5.5 * 10^(-6) m.

Sandra is making vegetable soup. If she makes 12 cups of soup, how many cups of onions does she need? Each 3 cups uses 1/8 of onions

Answers

Sandra will need 1/2 cup of onions
1/8 cup onions for every 3 cups of soup
3 x 4 = 12
1/8 x 4 = 1/2
BRAINLIEST PLEASE! thank you

Answer:

1/2 or 0.5

Step-by-step explanation:

For 3 cups she needs 1/8 of onions.

so for 1 cup she will need 1/8 ÷ 3 = 1/8 × 1/3 = 1/24.

for 1 cup of soup she needs 1/24 of onions.

For 12 cups of soup, she will need 12 × 1/24 of onions

12/1 × 1/24 = 12/24 = 1/2 or 0.5

Which information is needed to show that a parallelogram is a rectangle?

Answers

If you know for a fact that it's a parallelogram, then you only
need to show that any one angle is a right angle (90 degrees),
and that will prove that it's a rectangle.
If a parallelogram has right angles (angles with measures of 90 degrees) for all its angles, it is a rectangle.

Select the postulate that states a line is determined by two points.1. Postulate 1: A line contains at least two points.
2. Postulate 1a: A plane contains at least three points not all on one line.
3. Postulate 1b: Space contains at least four points not all on one plane.
4. Postulate 2: Through any two different points, exactly one line exists.
5. Postulate 3: Through any three points that are not one line, exactly one plane exists.
6. Postulate 4: If two points lie in a plane, the line containing them lies in that plane.
7. Postulate 5: If two planes intersect, then their intersection is a line.

Answers

4. Postulate 2: Through any two different points, exactly one line exists.

Postulate 2 and Postulate 1 are the only two postulates that really make sense. Postulate 2 is your answer instead of Postulate 1 for the following reason:

Postulate 1 states that a line contains at least two points.
Postulate 2 states that through any two different points, exactly one line exists.

Postulate 1 says that all lines contain at least two points, while Postulate 2 says that two points contain a line.

Answer:

Postulate 2: Through any two different points, exactly one line exists.

Answers

Answer:

20 cakes

Step-by-step explanation:

Given

28 cakes in 7 days

Required

Determine the number of cakes in 5 days

Represent the required with x. The question illustrates proportionality.

First, we need to represent the given and required as a ratio

28 : 7 = x : 5

Convert ratios to fraction

(28)/(7) = (x)/(5)

4 = (x)/(5)

Solve for x

x = 4 * 5

x = 20

A patio has a length of 8 feet and a width of x + 2 feet . Write and expression in simplest form for the perimeter of the patio

Answers

Answer:

2(x + 10)

Step-by-step explanation:

The perimeter is all the sides added together so you times the length by 2, (8 × 2 = 16). Then the width by 2 ( 2 × (x+2) = 2x + 4) add them together

16 + 2x + 4

2x + 20

take out the highest common factor of 2

2(x + 10)
