Answer:

D. 3*10^2

Step-by-step explanation:

Given the diameter of human red blood cell =  0.000009 m

diameter of a cold virus = 0.00000003 m

To know how many times as large is the diameter of a red blood cell as the diameter of a cold virus, we will take the ratio of the diameter of human red blood cell to that of a cold virus as shown;

diameter of human red blood cell/diameter of a cold virus = 0.000009 m/0.00000003 m

= 9*10^-6/3*10^-8

= 9/3 * 10^-6-(-8)

= 3 * 10^(-6+8)

= 3*10^2

Hence the diameter of a red blood cell is 3*10^2 larger than that of the cold virus

Answer:

Let us consider that the smallest angle is 'x'.

According to the given ratio, the four angles are:

Now, for any quadrilateral, the sum of the all four angles should be equal to 360°.

So,

        x + 2x + 3x + 4x = 360°

        10x = 360°

         x = 36°.

Thus, the four angles are:

Angles B and D are corresponding angles. This means D = B since corresponding angles are congruent when we have parallel lines.

Then note how D+E = 180 as these two angles form a straight angle.

Replace D with B getting B+E = 180 (this is the substitution property).

Alternatively, you can say that G = E and B+G = 180 to lead to B+E = 180. There are many other routes to take as well.

Answer: 210

Step-by-step explanation:

f(x) = 10(3 - 2x)

f(-9) = 10(3 - 2(-9)

f(-9) = 10(3+18)

f(-9) = 10(21)

f(-9) = 210

Answer:

[tex]12 + 5h \leq 18 + 3h[/tex]

Step-by-step explanation:

Given

Represent Derrick's with D and Pauline's with P

For D

Registration Fee = $12

Hourly Charges = $5

For P

Registration Fee = $18

Hourly Charges = $3

Required

Represent as an inequality such that D is at most of P

First, we need to represent both as an expression:

For D

[tex]D: 12 + 5h[/tex]

For P:

[tex]P:18 + 3h[/tex]

Since D is at most of P;

This implies that:

[tex]D \leq P[/tex]

So, we have:

[tex]12 + 5h \leq 18 + 3h[/tex]

Answer:

It would take 45 minutes to get 18 marks

Step-by-step explanation:

30 ÷ 12 = 2.5

2.5 x 18 = 45

It would take 45 minutes to get 18 marks

Answer:

E. People once thought animals were individually create by some superior.

But the solid creation of theory of origin of species by the naturalist Charles Darwin demonstrated a different theory.

Step-by-step explanation:

Before Charles Darwin several scientists were discussing the hypothesis of a theory of evolution. But it was Darwin whom put together all the information with reliable explanation and correlation between animal specialization and environment accordyinly with time.

He spent almost five years on board the ship HMS Beagle, crossing several continents, starting with South America. From there, he returned with dozens of specimens of living species, illustrations and fossils. Those specimens helped Darwin in his discoveries which originated the book On the Origin of Species published in 1859.

Step-by-step explanation:

PIN stands for Personal Identification Number. Option d is correct.

An alphanumeric or numeric string called a personal identification number (PIN) is used to verify a person's identity in a system.

Automated Teller Machines (ATM) for a bank, are the primary use cases for PINs (ATM). PINs are frequently used in place of more complex passwords to unlock mobile devices and authenticate users to applications.

Along with the development of the ATM, PINs were invented in the UK. In 1967, Barclays debuted ATMs as a convenient way for consumers to obtain cash. They also introduced ATM check deposits, which made use of codes printed on checks to help correctly account for such transactions.

Answer:

50°

Step-by-step explanation:

Hope this helps and is correct

60 degrees

This triangle is a right triangle, which means One angle measure of the triangle is 90 degrees. And the given angle is 40 degrees. The total sum of all the angles in a triangle is 180 degrees.

So if you add 40 + 90 + x = 180

You get 130 + x = 180

If you subtract 180 - 130

You get 60.

The value of "x" will be "7".

Given:

When "m" is parallel, then

→      [tex]m_2=m_6[/tex]

By substituting the values, we get

→ [tex]6x+8=8x-6[/tex]

By adding "6" both sides, we get

→ [tex]6x+8+6=8x-6+6[/tex]

→      [tex]6x+14=8x[/tex]

By subtracting "6x" from both sides, we get

→  [tex]6x+14-6x=8x-6x[/tex]

Distance between both points = 13

We have to find value of x[tex].[/tex]

Distance between two points can be measured by using this formula :

⭆ d = √[(x₂ - x₁)² + (y₂ - y₁)²]

⭆ 13 = √[(x - (-2))² + (-7 - 5)²]

⭆ 13² = (x + 2)² + (-12)²

⭆ 169 = (x + 2)² + 144

⭆ (x + 2)² = 169 - 144

⭆ (x + 2)² = 25

⭆ x + 2 = 5

⭆ x = 5 - 2

⭆ x = 3
