What is 8.57x10-⁴ in standered form ?

So if I had this problem I would multiply 21 x 34= 714 then I would divide it by 14 which would get me 51. There would be 51 blocks in each group!

Shaun would have 51 groups of blocks if he separated them into groups of 14. We found this by calculating the total number of blocks Shaun originally had (714) and dividing by the new group size (14).

The problem is about finding the total number of blocks Shaun has. We first multiply the number of groups Shaun can make (34) by the size of each group (21), which gives us 714 blocks. Then, we find out how many groups he'd have if he separated the blocks into groups of 14 instead, by dividing the total number of blocks (714) by the new group size (14). So, Shaun would have 51 groups of blocks if he divided them into groups of 14.

Answer 82%

Step-by-step explanation:

The probability of drawing a single card from a standard 52-card deck is calculated using the formula 'Desired outcomes/Total outcomes'. For a specific card, the probability is 1/52. For a face card, it's 12/52 or simplified to 3/13.

In the context of your question about drawing a single card from a standard 52 card deck, it's important to first understand the composition of the deck. A standard deck comprises of 52 cards; four suits of 13 cards each. The suits are clubs, diamonds, hearts, and spades, with clubs and spades being black, while diamonds and hearts are red.

To calculate the probability of drawing a specific card, we need to use the formula for probability, which is Desired outcomes/Total outcomes. In your case, drawing a specified single card from a 52-card deck, there is only one desired outcome and the total number of outcomes is 52. Hence, the probability would be 1/52.

If you are looking for the probability of drawing, say a face card (jack, queen, king), remember the deck has 12 face cards. Hence, the probability becomes 12/52 = 3/13.

You are correct

3/(3 - 12i)

To simplify this, multiply both sides by (3 + 12i)

(3 - 12i)(3 + 12i)

Distributive property.

3(3 + 12i) - 12i(3 + 12i)

9 + 36i - 36i - 144i^2

Simplify.

9 - 144i^2

i^2 can be interpreted as -1.

9 + 144

Combine like terms.

153 is the simplified version of the bottom half of the expression.

Now for the top half.

3(3 + 12i)

Distributive property.

9 + 36i

We can simplify this further by factoring.

3(3 + 12i)/153

1 + 4i/17

1/17 + 4i/17 is the simplified version of the expression. (This is your answer.)

To write the expression in standard form, divide 3 by the quantity 3 - 12i and rationalize the denominator by multiplying by the conjugate of the denominator to simplify to (3 + 12i)/51.

To write the expression in standard form, ​​3 divided by (3 - 12i), you need to rationalize the denominator by multiplying both the numerator and denominator by the conjugate of the denominator to eliminate the imaginary part. The conjugate of 3 - 12i is 3 + 12i.

Therefore, multiplying by the conjugate gives you: (3/(3 - 12i)) x ((3 + 12i)/(3 + 12i)).

This simplifies to the standard form: (3(3 + 12i))/(3^2 - (12i)^2) = (3(3 + 12i))/(9 + 144) = (3 + 12i)/51.

To determine when a sunflower reaches a height of 3 meters, given it grows at a rate of 30 cm per week, we divide 300 cm by 30 cm per week to find that the sunflower will reach the height in the 10th week.

The question asks us to determine in which week a sunflower, which can grow 30 cm each week, reaches a height of 3 meters.

Calculation of Weeks Required for Sunflower to Reach 3 Meters:

Firstly, we need to convert the final desired height from meters to centimeters, since the growth rate is given in centimeters per week:

3 meters = 300 centimeters

Next, we divide the final desired height by the weekly growth rate to find the number of weeks:

300 cm / 30 cm/week = 10 weeks

Therefore, the sunflower reaches a height of 3 meters in the 10th week.

AB = 10 → C and BC = 10 → A

to calculate the lengths use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 3, -  4) and (x₂, y₂ ) = (5, 2 )

AB = √(5 + 3 )² + (2 + 4 )² = √(64 + 36 ) = √100 = 10 → C

with (x₁, y₁ ) = (5, 2 ) and (x₂, y₂ ) = (11, - 6 )

BC = √(11 - 5 )² + (- 6 - 2 )² = √(36 + 64 ) = √100 = 10 → A

Distance formula: d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

AB:

1- Substitute A (-3, -4) for (x₁, y₁) and B (5, 2) for (x₂, y₂)

2- Plug them in the formula:  AB = √ (5 - (-3))² + (2 - (-4))²

Lan need to save more than 5 weeks to earn at least $85.00

Step-by-step explanation:

Given :Lan has $25.00 in his piggy bank,and can save $12.00 from his allowance each week.

To Find : How many weeks will Ian need to save to earn at least $85.00

Solution :

Lan has $25.00 in his piggy bank

He can save per week = $12

Let x be the number of weeks

So, he can save in x weeks = 12x

So,. total saving in x weeks = 25+12x

Now we are given that Ian needs to save at least $85.00

So, Equation becomes : [tex]25+12x>85[/tex]

So,  [tex]25+12x>85[/tex]

[tex]12x>60[/tex]

[tex]x>5[/tex]

Hence Ian need to save more than 5 weeks to earn at least $85.00 .

The number of small bottles the pharmacist can fill from the larger bottle and still have 250 milliliters remaining can be discovered through a mathematical operation, presumed to be a subtraction-based inequality. This would determine that the amount in the larger bottle, minus the total amount in the small bottles, is equal to or greater than 250 ml.

Unfortunately, the question lacks an inequality to be solved. However, we can assume that the problem may involve a mathematical operation including subtraction, since the pharmacist wants to keep a certain amount of milliliters (250 ml) left in the bigger bottle. In that case, the amount of syrup in the larger bottle minus the total amount of syrup placed into the small bottles should be equal to 250 ml.

Conceptually, this can be understood as follows:

If 'a' is the total quantity in the larger bottle, 'x' is the quantity which each smaller bottle can contain, and 'n' is the number of smaller bottles, we can create an inequality as follows: a - nx >= 250. This inequality means that the pharmacist can fill 'n' number of smaller bottles and still be left with at least 250 ml in the larger bottle.

So, solving this formula would yield the number of bottles that can be filled without reducing the larger bottle's quantity below 250 ml.

The pharmacist can fill any number of small bottles x  that satisfies the inequality:  [tex]\[ x \leq \left\lfloor \frac{L - 250}{S} \right\rfloor \][/tex]

The correct statement describing the number of small bottles the pharmacist can fill is that the pharmacist can fill x small bottles, where x is any integer less than or equal to the quotient of the volume of the larger bottle minus 250 milliliters, divided by the volume of one small bottle.

 To solve this problem, let's denote the volume of the larger bottle as L milliliters and the volume of each small bottle as S milliliters.

The pharmacist wants to fill x small bottles and have 250 milliliters remaining in the larger bottle.

Since the pharmacist can fill the small bottles until there is no more volume left to fill an additional bottle, the inequality that represents this situation is:

[tex]\[ xS \leq L - 250 \][/tex]

To find the maximum number of small bottles that can be filled, we divide both sides of the inequality by S

[tex]\[ x \leq \frac{L - 250}{S} \][/tex]

In summary, the pharmacist can fill any number of small bottles x  that satisfies the inequality:

[tex]\[ x \leq \left\lfloor \frac{L - 250}{S} \right\rfloor \][/tex]

-3.3=[tex]\frac{x}{6}[/tex]

Multiply both sides of the equation by 6 to isolate x.

The total change in the tram's elevation is 567 meters.

The total change in the tram's elevation can be found by multiplying the upward speed by the time it was moving. In this case, the tram moved upward at a speed of 9 meters per second for 63 seconds. So, the total change in elevation would be 9 meters per second multiplied by 63 seconds, which equals 567 meters.

Answer:

Option C. (4, -1, 3)

Step-by-step explanation:

The given system of equations is

x + y + z = 6 -----(1)

x - y + z = 8 ------(2)

x + y - z = 0 -----(3)

We subtract equation 1 by 3

(x + y + z) - (x + y - z) = 6 - 0

z + z = 6

2z = 6

z = 3

Now we subtract equation 1 by 2

(x + y + z) - (x - y + z) = 6 - 8

2y = -2

y = -1

Now we put the values of x and y in equation 1

x + (-1) + 3 = 6

x + 2 = 6

x = 6 - 2 = 4

Therefore, the solution of the equations is (4, -1, 3).

Option C is the answer.
