The rounded value of 5,672,874,627 is 5,673,000,000

What is a rounded value?

When a number is rounded, its value is kept relatively constant while being made easier. The outcome is simpler to use but less precise. Since 73 is closer to 70 than to 80, it is 70 when rounded to the nearest ten. But 76 increases to 80.

5,672,874,627

2 is in the million column

5,672,874,627

The nearest million could be 5,672,000,000 or 5,673,000,000.

To round to the nearest million, look at the digit in the column to the right, the hundred thousands.

5,672,874,627

The number in the hundred thousands column is 8.

The rule is, if the number is 5 or more, round up

5,673,000,000

Therefore, the rounded value of 5,672,874,627 is 5,673,000,000

This statement is False:

"21- to 24-year-olds in the us have the lowest percentage of drivers in fatal crashes with bac levels of .08% or higher."

A traffic collision, also known as a motor vehicle collision, car accident, or car crash, happens when a vehicle strikes another vehicle, a pedestrian, an animal, road debris, or another immovable object, like a tree, pole, or a structure.

An injury that is not fatal under this approach is one that results from prolonged exposure to an outside force or substance (mechanical, thermal, electrical, chemical, or radiation) or from submersion. Both deliberate and inadvertent bodily harm may occur.

Severe injuries are most frequently dealt to the neck, followed by the head, chest, legs, and abdomen/pelvis, for passengers riding on the side of the automobile that was impacted. For those riding in vehicles on the contralateral side of the car, head injuries are most common, followed by chest injuries.

The product of two given numbers in terms of scientific notations is 1.36 × 10^(22).

What are scientific notations?

Scientific notations are a way of representing either a very small or a very large number in the powers of 10. Scientific notations comprise digits from 1 to 9 with powers of 10.

Calculation of the product of two numbers

Given two numbers are 3.2 × 10^(12) and 4.25 × 10^(9)

Multiplying two numbers, we get

= 3.2 × 10^(12) × 4.25 × 10^(9)

= 13.6 × 10^(21)

= 1.36 × 10^(22)

Hence, the product of two numbers in terms of scientific notations is 1.36 × 10^(22).

Answer: m = 13 kg

Step-by-step explanation:

      This question gives us the formula to use. We will plug-in the values we know and solve for the unknown (mass).

   Given:

F = ma

   Plug-in known values:

(65 kg m/s²) = m(5 m/s²)

   Divide both sides of the equation by 5 m/s²:

The m/s² unit cancel out, so we are left with kg.

m = 13 kg

       The mass of the object is 13 kg.

The expression for M from the given function is M = 4π²a²/T²G

The subject of a formula is the variable that is being worked out from a given equation.

Given the equation below;

T² = 4π²a²/GM

We are to make M the subject of the formula

T²GM = 4π²a²

Divide both sides by T²G

T²GM/T²G = 4π²a²/T²G

M = 4π²a²/T²G

Hence the expression for M from the given function is M = 4π²a²/T²G

Answer: B.

Step-by-step explanation:

   First, we will solve both of these given inequalities for x by isolating the variables.

Given:

   6 + 3y < 9

Subtract 6 from both sides of the equation:

   3y < 3

Divide both sides of the equation by 3:

   y < 1

--

Given:

   4y > 3y + 2

Subtract 3y from both sides of the equation:

   y > 2

   Now, our given inequalities are y < 1 and y > 2. These inequalities are easier to view on the graph. We see that these are not equal to (≥ or ≤), so we will have open circles.

   First, we will graph y < 1. We will plot an open circle at y = 1 and then shade to the left of it. Net, we will graph y > 2. We will plot an open circle at y = 2 and then shade to the right of it. This leaves us with answer option B.

Answer:

c=5+1h

Step-by-step explanation:

The equation for where h represents the number of hours and C represents the total cost is C = 5 + nh.

Given that the skates were rented for $5 and pay $1 an hour for skating per person.

We need to write an equation, where h represents the number of hours and C represents the total cost.

To calculate the total cost (C) for a family with h hours of skating, you would need to consider the cost of renting skates ($5) and the cost of skating per person per hour ($1 per person per hour).

Let n be the number of people in the family.

The equation for the total cost (C) can be expressed as follows:

C = 5 + nh

The $5 is added to the equation as a one-time cost for renting skates, which is the same for any number of people.

nh represents the cost for the number of people (n) skating for h hours, at the rate of $1 per person per hour.

The cost per person is multiplied by the number of hours they skate.

Hence the required equation is C = 5 + nh.

A solution of 150 h is administered at a rate of 8 ml / hr.

We express the answer in terms of mg/hr m g / h r

90 mg dopamine / 20 ml = 4.5 mg/ml

4.5 mg/ml * 8 ml/h = 36 mg/h

90 mg * 1 h / 36 mg= 150 h to administer -- using the inverse of 90 mg per 1 hour and cancelling mg in numerator and ml denominator.

Hence, 150 h is administered at a rate of 8 ml / hr.

Let's see a few examples to understand the statement given in the question.

Example 1:

Find the sum of 75.5 + (58.231 + 24.5)

Hence , the sum of 75.2+(57.376+24.8) is 158.231.

75.5 + (58.231 + 24.5)

= 75.5 + (24.5 + 58.231) (using the commutative property of addition)

= (75.5 + 24.5) + 58.231 (using the associative property of addition)

= 100 + 58.231 (by looking at the first two numbers, it is easier to say that the sum is 100.)

= 158.231 (you can write this answer directly without doing any calculation)

Therefore, the sum of 75.2+(57.376+24.8) is 158.231.

Example 2:

Find the product of (25 × 2) × 50

Hence , the product is 2500 .

(25 × 2) × 50

= 25 × (2 × 50) (using the associate property of multiplication)

= 25 × 100

= 2500 ( we can simply add to zeros at the end if an integer number is multiplied by 100.)

Therefore, the product of (25 × 2) × 50 is 2500.

Many challenging questions do not involve numerical or geometrical considerations but call for deductive inferences based chiefly on logical relationships. Such puzzles are not to be confounded with riddles, which frequently rely upon deliberately misleading or ambiguous statements, a play on words, or some other device intended to catch the unwary. Logical puzzles do not admit of a standard procedure or generalized pattern for their solution and are usually solved by some trial-and-error method. This is not to say that the guessing is haphazard; on the contrary, the given facts (generally minimal) suggest several hypotheses. These can be successively rejected if found inconsistent, until, by substitution and elimination, the solution is finally reached. The use of various techniques of logic may sometimes prove helpful, but in the last analysis, success depends largely upon that elusive capacity called ingenuity. For convenience, logic problems are arbitrarily grouped in the following categorie
