Answer:

(8-(3+b))3

Step-by-step explanation:

first of all, we have to variables, 3 and b that we are told to add

that is, 3+b

we are now told to subtract the answer from 8

that is 8 minis the answer

= 8- (3+b)

lastly we triple the answer to give

(8-(3+b)3

or

3(8-(3+b)

Answer:

Step-by-step explanation:

it is like 9x9=81

but yeah like he said it is a square so all sides are the same

but that is if you want to find the parameter

this question is talking about area

so when a question gives you an area you ask yourself what can be multiplied by what in order to give me the area

or since all sides are the same like he said you could just do simple division and do 81/9 which will =9

and since the question mentions that the area is in square inches it is obvious that the answer would be put in inches

answer: 9 inches

Answer:

p = 7

Step-by-step explanation:

i think there's a proper equation to solve these kinds of problems but you can think about numbers times 6 (1x6 = 6, 2x6 = 12, 3x6 = 18,...)

The value of p will be 7.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

p is a whole number.

And, 6p is greater than 40 and less than 45.

Now,

Since, 6p is greater than 40 and less than 45.

Hence, We can formulate;

⇒ 40 < 6p < 45

Solve for p as;

⇒ 40 < 6p < 45

Divide by 6, we get;

⇒ 40/6 < 6p/6 < 45/6

⇒ 6.67 < p < 7.5

Since, p is a whole number.

Hence, The value of p = 7

Thus, The value of p will be 7.

Answer:

  2x -3y = 21

Step-by-step explanation:

The perpendicular line will have an equation with the x- and y-coefficients swapped and one of them negated. The constant will be the value that makes the equation true at the given point.

  3x +2y = 6 . . . . . given equation

  2x -3y = c . . . . . . coefficients swapped, one negated

  2(6) -3(-3) = c = 21 . . . . . the value of c for the given point

The desired equation is ...

Answer:

  D. (-∞, 4]

Step-by-step explanation:

The range is the vertical extent of the graph. The graph extends off the bottom, so the lower end of the range is -∞. The peak values are y=4, so the upper end of the range is 4.

Expressed in interval notation, the range is ...

  (-∞, 4]

_____

Additional comment

The right-side bracket is square because the value 4 is included in the range. The left side bracket is rounded because there's no specific number equal to -∞. We can only say the lowest value of y is greater than -∞.

Answer: (-∞, 4]

Step-by-step explanation: Top of function stops at 4, and is negatively continuous.

Answer:

Jupiter's diameter is "about" 21 times greater than Mars with an exact answer of around 20.588

Step-by-step explanation:

Jupiter = 1.4 x [tex]10^{5}[/tex] = 140,000

(1.4 "plus 5 places" is how I think of it to make it easier)

Mars = 6.8 x 10³ = 6,800

To find how many times greater Jupiter is than Mars we can divide tje diameter of Jupiter by Mars:

140,000 / 6,800 = 20.588235 etc

I am not sure how far you are rounding, but Jupiter's diameter is "about" 21 times greater than Mars

Answer:

Mao will say more numbers

Step-by-step explanation:

Mao will say more numbers because, to get to 30, you must count by fives 6 times. For example, 5,10,15,20,25,30. There are 6 numbers there. On the contrary, Alana is only going to count 4 times. 10,20,30,40. 6 is greater than 4, therefore Mao will say more numbers. I hope this helps!

Answer:

110 dollars.

Step-by-step explanation:

Since every day you owe him 2 dollars more, and its been 25 days, 25 x 2 is 50.

You originally owed him 60, and 50 dollars in late fees, so 60 + 50 = 110.

You owe him 110 dollars.

Answer:

x ≤14.5

Step-by-step explanation:

4x+16≤74

Subtract 16 from the 74 and that gives you 58

Then divide each side by 4. 58/4=14.5

Hope this helps! sry if I get it wrong! :(

Answer: x ≤ 29/2

Explanation:

Subtract 16 from both sides

4x + 16 - 16 ≤ 74 -16

Simplify

4x ≤ 58

Divide both sides by 4

4x/4 ≤ 58/4

Simplify

x ≤ 29/2

Answer:

262144

Step-by-step explanation:

Geometric sequence : -1 , 4 , -16 , 64 .....

Ratio = 2nd term ÷ 1st term = 4 ÷ (-1)= -4

a =  first term = -1

r = -4

Each term is obtained by multiplying the previous term by (-4)

nth term = [tex]ar^{n-1}[/tex]

10th term = [tex](-1) * (-4)^{9}= -1 * (-262144) = 262144[/tex]

Answer:

<

Step-by-step explanation:

Firstly, you can focus on the scientific notation and calculate which one is bigger. The left side is [tex]10^3[/tex] whereas the right side is [tex]10^4[/tex]. This shows that even if the number before this was bigger, the larger exponent of these two are the bigger number.

[tex]10^3 = 1000\\10^4 = 10000[/tex]

Meaning the correct sign would be the smaller than sign (<) as the right side is bigger than the left.

Hope this helps!
