The result of the formula  \(12 - 3y2 + (v=4) / (2y - 2)\) for y = 3 is  \(-29/2\)  .

When \(y = 3\) is used, the value of the expression \(12 - 3y2 + (v=4) / (2y - 2)\)  has a value of  \(-29/2\) .

To analyse an algebraic expression is to determine its value when a certain number is used in lieu of the variable. To evaluate the expression, we first replace the variable with the given number, then we use the order of operations to simplify the expression.

If  \(y = 3\) , we can insert it into the expression & simplify as follows to evaluate   \(12 - 3y2 + (v=4) / (2y - 2)\) for  \(y = 3\)  .

\(12 - 3(3)^2 + (√4) / (2(3) - 2)\) (y = 3 replacement)

\(12 - 27 + 2 / 4\s-15 + 1/2\s-29/2\)

Therefore, The result of the formula  \(12 - 3y2 + (v=4) / (2y - 2)\) for y = 3 is  \(-29/2\)  .

6. -3/4

The formula for y in terms of x is y=160​/x^2.

We are given that;

y = 20 when t=4

And t = 8 when x = 2

Now,

To find the value of k by using the fact that y = 20 when t = 4:

20=k⋅4

k=5

Also, y=5t

Next, we use the fact that t is inversely proportional to the square of x. We can write:

t=x2k​

where k is a constant of proportionality. We can find the value of k by using the fact that t = 8 when x = 2:

8=22k​

k=32

Now we know that:

t=x232​

Substituting this into the equation for y:

y=5t=5⋅x232​=160​/x^2

Therefore, by proportions the answer will be y=160​/x^2.

Step-by-step explanation:

why are you panicking ? there is no reason for panic. just take a deep breath and then use common sense and basic logic.

what do you see ?

you see 1 can. in a 1×1 configuration.

you see 4 cans in a 2×2 configuration.

you see 9 cans in a 3×3 configuration.

how will it continue ? what do you think ?

and what is that configuration shape ? hmmm ?

it is a square, plain and simple : the same number of units for the length and the width.

and since every layer is then clearly adding 1 can in every direction, it continues with 4×4, 5×5, 6×6, ...

and the 9th layer is ... hmm ? 9×9 ! Tatah !

and so, the number of cans in every layer are the sequence of square numbers : 1 (1²), 4 (2²), 9 (3²), 16 (4²), ...

and the 9th layer has then 9² (or 9×9) = 81 cans.

you really think this was difficult ?

I cannot believe that.

just take another look without any panic and think it through.

here is the answer 1,000,700

The standard form of "one million seven hundred" is 1,000,700.

The standard form of a number refers to the representation of a number using digits and place value notation. It is also known as the decimal form or the base-10 form.

We have,

"one million seven hundred"

In standard form, numbers are written using place value notation, where each digit is assigned a position based on its place value.

In the case of "one million seven hundred," the digit 1 represents one million, the digit 7 represents seven hundred, and the remaining zeroes represent placeholders for the tens, ones, and smaller place values.

So, by combining the place values, we can express "one million seven hundred" in standard form as 1,000,700, where the 1 represents one million, the 0s serve as placeholders for the smaller place values, and the 7 represents seven hundred.

Answer:

84 cookies

Step-by-step explanation:

First, find the amount she bakes per minute. It is given that Marissa bakes 30 cookies every 15 minutes, or:

30 cookies/15 minutes = 2 cookies/minute.

Marissa bakes 2 cookies per minute. Multiply 2 with 42 minutes to find the total cookies baked in 42 minutes:

42 x 2 = 84

84 cookies is your answer.

~

Answer: 84 cookies

Step-by-step explanation:

30 cookies = 15 minutes

? cookies = 1 minute

30 ÷ 15 = 2

2 cookies = 1 minute

? cookies = 42 minutes

2 x 42 = 84

84 cookies = 42 minutes

Step-by-step explanation:

To simplify the expression x^-2y(x^3y^5)^3, we need to perform the operations inside the parentheses first, using the exponent rule that (a^m)^n = a^(mn):

x^-2y(x^3y^5)^3 = x^-2y(x^(33)y^(53)) = x^-2y(x^9y^15)

Next, we can simplify the expression by multiplying the coefficients (numbers) and adding the exponents of x and y, using the product rule that x^mx^n = x^(m+n) and (xy)^m = x^my^m:

x^-2y(x^9y^15) = (1y/x^2)(x^9*y^15) = y^(15+1)x^(9-2) = y^16x^7

Therefore, the simplified form of x^-2y(x^3y^5)^3 is y^16*x^7.

Note that this expression is defined for all values of x and y except for x=0.

The models that represent the sum 1.2 + 0.3 are

Option 3 and Option 5

For Option 3:

The first square represents 1.2, with all 10 columns shaded in one color. The next two columns represent 0.3, shaded in a different color. The sum of 1.2 and 0.3 is 1.5, which is represented by the combination of the two squares.

For Option 5:

On the number line, the first arrow represents 1.2, starting from 0 and ending 2 marks past 1, which is equal to 1.2. The second arrow represents 0.3, starting from 2 marks past 1 and ending at 5 marks past 1, which is equal to 1.5. The sum of 1.2 and 0.3 is 1.5, which is represented by the end point of the second arrow on the number line.

Since both the divisor and the dividend have the same decimal places, we do the following:

1. We move the decimal point of the divisor all the way to the right

2. We move the decimal point of the dividend the same number of places we moved the decimal point on the divisor

3. We divide as usual

This series of steps will look like this:

= 8.24e3

(scientific e notation)

= 8.24 × 103

(engineering notation)

(thousand; prefix kilo- (k))

= 8240

(real number)

How do you convert from scientific notation to standard form?

To change a number from scientific notation to standard form, move the decimal point to the left (if the exponent of ten is a negative number), or to the right (if the exponent is positive). You should move the point as many times as the exponent indicates.

Answer:

p=1

Step-by-step explanation:

first you need to get rid of the parenthesis

-2p+8=6-7p+7

then combine everything you can on their respective sides

-2p+8=13-7p

then get the variable on one side and for this, it can be done 2 different ways but both ways get the same answer

-2p+8=13-7p

+7p         +7p

5p+8=13

or

-2p+8=13-7p

+2p         +2p

8=13-5p

then, depending on which way you decide to solve it, you would then solve for x like you would in any regualar equation

first way shown above:

5p+8=13

    -8  -8

5p=5

divide them both by 5 and p=1

or the other way shown above

8=13-5p

-13  -13

-5=-5p

divide both sides by -5 and then p=1

The value of the expression |−3d − 6| + |−5 − d²| when d = -3 is 17.

Given expression: |-3d - 6| + |-5 - d²|, and d = -3

Substitute the value of d: |-3(-3) - 6| + |-5 - (-3)²|

Calculate the values inside the absolute value signs:

|-(-9) - 6| + |-5 - 9|

Simplify the inside calculations:

|9 - 6| + |-5 - 9|

Continue simplifying:

|3| + |-14|

Calculate the absolute values:

3 + 14

Add the values together:

3 + 14 = 17

So, the value of the expression |−3d − 6| + |−5 − d²| when d = -3 is 17.
