Answer:

Jon types 54 words per minute.

Step-by-step explanation:

If Jon typed 36 words in 2/3 of a minute, we need to divide 36 by 2.

36 ÷ 2 = 18

Therefore, Jon types 18 words in 1/3 of a minute. In order to find how many words are typed per minute, we must multiply 18 by 3.

18 x 3 = 54

Therefore, Jon types 54 words per minute.

Step-by-step explanation:

Making r the subject of the formula, r is solved as: B. r = (27 - P)/3P.

Given the formula, A = P(1 + rt), where:

A = 27 and t = 3

To solve for r, make r the subject of the formula as shown below:

A = P(1 + rt)

Divide both sides by P

A/P = 1 + rt

Subtract 1 from both sides

A/P - 1 = rt

(A - P)/P = rt

Multiply both sides by 1/t

(A - P)/P × 1/t= rt × 1/t

(A - P)/Pt = r

r = (A - P)/Pt

Substitute A = 27 and t = 3 into the formula

r = (27 - P)/P3

r = (27 - P)/3P

Therefore, making r the subject of the formula, r is solved as: B. r = (27 - P)/3P

Step-by-step explanation:

Answer:

158 natural numbers from 78 to 234, and 699 whole numbers from 24 to 721.

Step-by-step explanation:

Natural numbers are positive integers (whole numbers), so all numbers from the range of 78 to 234 would be included, including 78 and 234 itself. That is 158 natural numbers. Whole numbers are numbers without a fraction or decimal, they are integers. So all numbers from 24 to 721 would be included, as well as 24 and 721 itself. That is 699 whole numbers from 24 to 721.

The first equation given as 7x + ( -6 ) = 6x - 2 is True.

The second equation given as 7 + 2x = 3x + 3 = 4 is false

Given data

7x + ( -6 ) = 6x - 2

7 + 2x = 3x + 3 = 4

The first equation

7x + ( -6 ) = 6x - 2

solving for x gives

7x  - 6 = 6x - 2

7x - 6x = 6 - 2

x = 4

checking for the value

7x + ( -6 ) = 6x - 2

7 * 4 - 6 = 6 * 4 - 2

28 - 6 = 24 - 2

22 = 22

Hence we say the expression in the first equation is true

The second equation

7 + 2x = 3x + 3 = 4

7 + 2x = 3x + 3

7 - 3 = 3x - 2x

4 = x

checking for the value of x

7 + 2x = 3x + 3

7 + 2 * 4 = 3 * 4 + 3

7 + 8 = 12 + 3

15 = 15

15 = 15 ≠ 4 false

The first equation is true while the second equation is false

Answer:

16 square feet was left over after he cut out the windows

Step-by-step explanation:

The formula of the area of a rectangle is A = l × w, where

∵ The dimensions of each window are 8-foot by 4-foot

∴ l = 8 feet and w = 4 feet

→ By using the rule above find the area of each window

∵ A = 8 × 4

∴ A = 32 feet²

∴ The area of each window = 32 feet²

∵ He cut 2 windows

∴ The area of the 2 windows = 2 × 32

∴ The area of the 2 windows = 64 feet²

∵ The area of the wall is 80 feet²

→ To find the area of the wall left, subtract the area of the windows from

   the area of the wall

∵ The area left = 80 - 64

∴ The area left = 16 feet²

∴ 16 square feet was left over after he cut out the windows

Answer:

n=-18

Step-by-step explanation:

Steps:

multiply 3 by both sides of the equation

2. cross out the 3 from [tex]3(\frac{2}{3} )[/tex] and you will get 2 and then do -12 x 3 and you will get -36.

3. you now have 2n=-36

4. divide both sides by 2 to isolate n by itself.

[tex]\frac{2n}{2} =\frac{-36}{2}[/tex]

5. divide by crossing out 2 and 2 on the right and then do -36 ÷ 2 which will give you n= -18

Hope this helps :) if you have any questions let me know.

Hi!

To find the value of n in the given equation, multiply both sides by 3.

That way, you'll clear the fractions and solving for n will be easier.

[tex]\implies\boldsymbol{\displaystyle\frac{2}{3} n\times3=-12\times3}[/tex]

Watch what happens:

[tex]\implies\boldsymbol{\displaystyle\frac{2}{\not3} n\times\not3=-36}[/tex]

On the LHS, the 3's cancel out, and we're left with 2n:

[tex]\implies\boldsymbol{2n=-36}[/tex]

Now, divide both sides by 2:

[tex]\implies\boldsymbol{n=-18.}[/tex]

Voila! There's our solution.

Have a nice day!

Answer:

The first time, the ant went 2m away, then we have a₁ = 2m

The second time, the ant went 3m away, then we have a₂ = 3m

The next time, the ant went a distance equal to the sum of the two previous ones, so we can write it in a general case as:

aₙ = aₙ₋₁ + aₙ₋₂

Only if n > 2.

then the third time, we have n = 3.

a₃ = a₂ + a₁ = 2m + 3m = 5m

a₄ = a₃ + a₂ = 3m + 5m = 8m

a₅ = a₄ + a₃ = 5m + 8m = 13m

This means that in the fifth trip, the ant went 13 meters away from its nest.

And if we consider the fact that the ant must go and return, then it will move a total distance of 13 meters two times, or 2*13m = 26 meters.

Answer:

the exact answer is 58.65

Step-by-step explanation:

since she made 85% of her shots, that means in total from her 51 shots, she made 115% more than 51 (you add 15% to 100%). The 15% is from the difference of 100% and 85%. You then change 115% to fraction form (1.15) and multiply it by the amount of shots made, getting you 58.65. Since you can't make a fraction in terms of a real life scenario like this, you prob need to round or something. Diff teachers want diff things

C. From a starting point of 5 meters below sea level, the whale is descending 9 meters per second.

Step-by-step explanation:

Which statement best describes the depth of the whale, given this equation?

A. From a starting point of 9 meters below sea level, the whale is descending 5 meters per second.

B. From a starting point of 9 meters below sea level, the whale is ascending 5 meters per second.

C. From a starting point of 5 meters below sea level, the whale is descending 9 meters per second.

D. From a starting point of 5 meters below sea level, the whale is ascending 9 meters per second.

Solution:

A linear equation is an equation in the form y = mx + b, where m is the rate of change (slope) and b is the initial value of y when x = 0, y is a dependent variable and x is an independent variable.

Given that: y = -9x - 5

Comparing with the equation of a straight line, m = -9 and b = -5

Since m = -9, The negative sign means descending, therefore the whale is descending at 9 meters per second.

b = -5, the negative sign means below sea level, hence the starting point of the whale is 5 meters below sea level,

Therefore, we can classify the polynomial as a quadratic polynomial.

A polynomial is a mathematical expression that consists of variables and coefficients, and involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. Polynomials can have one or more variables and may contain multiple terms. Each term consists of a coefficient and a variable raised to a power. The degree of a term is the power to which the variable is raised, and the degree of a polynomial is the highest degree of any of its terms. Polynomials are used in many areas of mathematics, science, and engineering, such as algebra, calculus, geometry, and physics. They are used to model real-world phenomena, to solve equations, and to approximate complex functions.

Here,

To write the polynomial 14y² - x² - 3xy in standard form, we need to arrange the terms in descending order of degree (highest degree term first) and combine like terms.

First, let's rearrange the terms:

x² - 3xy + 14y²

Now, the polynomial is in descending order of degree. We don't need to do anything else to put it in standard form.

To classify the polynomial, we count the number of terms and the highest degree of those terms. In this case, there are three terms and the highest degree term is 14y², which has degree 2.
