Answer:

1. 8.03 x 108 2. 6.8 × 10-9 3. 135,900 4. 2.5x10^-11

Step-by-step explanation:

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 803,000,000New Number: 8.03000000Step 2

Now, to find b, count how many places to the right of the decimal.

New Number:8.03000000Decimal Count:12345678

There are 8 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 8.03 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

8.03 x 108

Step 4

Check your work:

108 = 100,000,000 x 8.03 = 803,000,000

Step-by-step explanation:

860.55 mm

Explanation:

The surface area of an hexagonal prism, also known as an octahedron, is given by the following formula (since we have the apothem):

S= 6*b*(a+h)

where b = is the side of the base, a is the apothem length, and h = the height

S = 6 * 8 * (4√3 + 11) = 48 * 17.92812 = 860.55 sq mm

Could have also have used another formula without the apothem:

S =3 * √3 * b² + 6 * b * h

S = 3 * √3 * 8² + 6 * 8 * 11 = 3√3 * 64 + 528 = 332.55  + 528 = 860.55 sq mm

Answer:

a)

2x/3 = 8. First, multiply both sides by 3 to make 2x = 24. Then, divide both sides by 2: x = 12.

b)

3x/2 = 6. First, multiply both sides by 2 to make 3x = 12. Then, divide both sides by 3: x = 4.

Hope this helps!

Answer:

A.) x = 12

B.) x = 4

Step-by-step explanation:

A.) 2x/3 = 8

First let’s multiply both sides by three to get rid of our division equation,

2x/3 = 8

*3 *3

2x = 24

Now we divide both sides by 2 to single out our variable,

2x = 24

/2 /2

X=12

Let’s check our answer just to be sure this is correct, we do this by plugging in “12” for our x

2(12)/3 = 8

24/3 = 8

8 = 8

Now we know that x = 12 is true,

B.)3x/2 = 6

Again well will multiply both sides by 2 to remove our division equation,

3x/2 = 6

*2 *2

3x = 12

We divide both sides by 3 to remove our coefficient in front of the variable,

3x = 12

/3 /3

x=4

Let’s check our answer once again,

3x/2 = 6

3(4)/2 = 6

12/2 = 6

6 = 6

X = 4 is true

account balance =3500+1400=4900

compound p(1+r)^t

interest earned = 5180-3500= 1680

how much more interest. ; 1680-1400=280

Answer:

Step-by-step explanation:

Simple Interest:

Simple Interest formula is S.I. = P × r × t

Interest Eared: $3,500 × 0.04 × 10 = $1,400

Account Balance formula is A = P ( 1 + rt )

Account Balance: $3,500 + $1,400 = $4,900

Compound Interest:

Compound Interest formula: [tex]A =P(1+r)^{t}[/tex]

Account balance: $5,180.85

Interest Earned: $5,180.85 - 3,500.00 = $1,680.85

Step-by-step explanation:

Eighth-grade students tend to do better on the mathematics section compared to the reading and writing sections.

Bc math is 5 when writing is 3 and the reading is at 1 so math is better

Eighth-grade students tend to do better on the mathematics section compared to the reading and writing sections. Therefore, option D is the correct answer.

Given that, the two-way frequency table shows the number of students in a class whose top scores on a standardized test were on the reading, writing, and mathematics sections.

A frequency table lists a set of values and how often each one appears. Frequency is the number of times a specific data value occurs in your dataset. These tables help you understand which data values are common and which are rare.

By interpreting the given data table we get

Answer:

Step-by-step explanation:

[tex]y =\dfrac{-3}{4}x -6[/tex]

Multiply the entire equation by 4,

[tex]4*y=\dfrac{-3}{4}x*4 - 6*4\\[/tex]

4y = -3x - 24

Add 3x to both sides

3x + 4y = -24

Add 24 to both sides

3x + 4y + 24 = 0

Explanation:

Less Men, means more Days {Indirect Proportion}

Let the number of days be x then,

27 : 36 :: 18 : x

[Please pay attention, we have written 27 : 36 rather than 36 : 27, in indirect proportion, if you get it then chain rule is clear to you :)]

=>27x = 36 * 18

=> x = 24

So 24 days will be required to get work done by 27 men..

Answer:

36 men can complete work in 18 days

so, one man can complete work in 18×36 days

Therefore, 27 can complete work in 18×36/27 = 24 days

Step-by-step explanation:

80% = x

Kenny found 80% of the eggs.

Step-by-step explanation:

y = 3x - 6

the slope of a line is always the factor of x in the equation. in our case here : 3 = 3/1.

the slope is the y/x ratio indicating how many units y changes, when x changes by a certain amount of units (e.g. when going from one point on the line to another).

the perpendicular slope (crosses the original line in a right angle = 90 degrees) turns x and y upside-down and flips the sign.

so, in our case, it is -1/3.

the equation for the perpendicular line looks like this then :

y = (-1/3)×x + b

to get b we use the provided point and it's x and y values.

6 = (-1/3)×-3 + b = 1 + b

b = 5

so, the full equation of the perpendicular line is

y = (-1/3)×x + 5
