The number of minutes will it take him to mow the entire yard will be 50 minutes.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Dad mowed 60% of the yard in 30 minutes.

Let 'A' be the entire area of the lawn and 'x' be the total time to mow the entire lawn. Then 60% of the lawn is given as,

⇒ 60% of A

⇒ 0.60A

The ratio of the area of the lawn to time remains constant. Then the equation is given as,

0.60A / 30 = A / x

x = 30 / 0.60

x = 50 minutes

The number of minutes will it take him to mow the entire yard will be 50 minutes.

Hello,

I hope you and your family are doing well!

To calculate the amount of interest earned on a savings account, you can use the following formula:

interest = principal * rate * time

In this case, the principal is $9,500, the rate is 3.75%, and the time is 1 year. Plugging these values into the formula, we get:

interest = $9,500 * 3.75% * 1 year = $356.25

So, in a year, Alice would earn $356.25 in interest on her savings account.

The equation that represent the product of to consecutive numbers being 182 is x^2 + x -182 = 0

Quadratic equations are second-degree algebraic expressions and are of the form ax^2+ bx + c = 0. The word "Quadratic" is derived from the word "Quad" which means square. In other words, a quadratic equation is an “equation of degree 2.”

let the two consecutive negative numbers be -x and -x-1

their product - x( -x-1) = 182

multiply out you have

x^2 + x = 182

which is finally reduced to

x^2 + x - 182 = 0

What is factor?

In mathematics, an integer m that can be multiplied by another integer to produce n is known as a divisor of an integer n, also known as a factor of n. One can also state that n is a multiple of m in this situation.

Knowing that (x−2) is a factor you can divide the polynomial:

2.....|.......1.........-12.........+36.........-32

........|...................2..........-20.........+32

........|.......1.........-10..........+16...........0

and find:

[tex]x^3-12 x^2+36 x-32=(x-2)\left(x^2-10 x+16\right)[/tex]

We could use the quadratic formula to find the factors of [tex]$q(x)=\left(x^2-10 x+16\right)$[/tex]

or go simply by inspection:

1) q(x) has two changes in sign, so it has two positive real roots.

2) The product of the roots is 16

3) the sum of the roots is 10

It's easy to see that x=2 and x=8 are such roots, and thus:

[tex]x^3-12 x^2+36 x-32=(x-2)^2(x-8)[/tex]

The value of b is -11/2.

What is the slope of the equation?

The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).

To find the value of b, we need to find the slope of the given line and the line that is perpendicular to it.

The slope of the line 8x + 12y = 40 is -8/12 = -2/3.

The slope of a line that is perpendicular to this line is the negative reciprocal of -2/3, which is 3/-2 = -3/2.

The slope of the line y = (5 + b)x - c is 5 + b. Therefore, to find the value of b, we need to set 5 + b equal to -3/2:

5 + b = -3/2

b = -3/2 - 5

b = -11/2

Therefore, the value of b is -11/2.

Answer:

the number of terms N in the series is approximately 8.57, which is approximately equal to 9.

Step-by-step explanation:

The mean of a series is calculated by taking the sum of all the terms in the series and dividing it by the number of terms. In this case, the mean of the continuous series Efm=300+20m is given as x=15+m.

To find the number of terms N in the series, we can use the formula for the mean to solve for N. The formula for the mean is:

mean = sum of terms / number of terms

Substituting the given values, we get:

15+m = (300+20m) / N

We can then multiply both sides of the equation by N to isolate the sum of terms:

(15+m) * N = 300+20m

This simplifies to:

15N + mN = 300 + 20m

We can then combine like terms to get:

(15+20)N = 300

35N = 300

Dividing both sides by 35, we get:

N = 300/35

N = 8.57

Since the number of terms must be a whole number, the number of terms N in the series is approximately 8.57, which is approximately equal to 9.

the 96th term of the arithmetic sequence 3, -14, -25 is -1048.

An arithmetic sequence is an ordered set of numbers that have a common difference between each consecutive term.

The general form of an arithmetic sequence is

aₙ = a₁ + d(n-1)

where aₙ is the nth term, a₁ is the initial term, and d is the common difference.

Given that n =96, a₁=-3, and d = -11

Substituting these value in the above equation

a₉₆ = -3 - 11(96-1) = -3 - (11*95) = -3-1045 = -1048

Answer: Our answer set is( -1,-2 )

Step-by-step explanation:

y = x - 1

y = 3x + 1

We can use the combine method here.

==> - 1y + 1x = 1  (y = x - 1)

==>  -1y +3x = -1 (y = 3x + 1)

- 1y + 1x = 1  

 -1y +3x = -1

To single out any of the two variables, we need them to cancel out. Let us choose to cancel out y. We therefore multiply by negative 1 in the first re-arranged equation.

==> -1* (- 1y + 1x )= (1 ) * -1

Now we add the equations

Answer:

  (c)  12(2v-7)

Step-by-step explanation:

You want the expression resulting from factoring out the greatest common factor from the sum 24v -84.

The greatest common factor here is the GCF of 24 and 84. We note that ...

  24 = 12·2

  84 = 12·7

and 2 and 7 have no common factors. Then the GCF of 24 and 84 is 12.

The factored expression is ...

  24v -84 = 12(2v -7)

__

Additional comment

The GCF can also be found by considering the remainder from dividing 84 by 24. That remainder is 12, which divides both numbers with a remainder of 0. Hence 12 is the GCF.

If the remainder did not divide both numbers with a remainder of 0, then the process is repeated to find the GCF of the smaller number (24) and the remainder. (This is a description of Euclid's algorithm for finding the GCF.)

What is modulus function?

Regardless of whether a number is positive or negative, the modulus function, also known as the absolute value function, determines its magnitude. No matter what the number or variable, it always returns a non-negative value. The expression y = |x| or f(x) = |x|, where f: R (0,) and x R, denotes a modulus function.

When x is a real number, then |x| is its modulus. f(x) will have the same value as x if x is not negative. If x is negative, then f(x) will have the magnitude of x; if x is negative, then f(x) = -x. Here is a summary of the modulus function formula.

As we can see in the graph attached that the f(x) is zero at y=-8 and it is a modulus function so the graph will open upwards

but the graph is little shifted to y=-8 because the equation given to us is |x|-8 =g(x) so it will shift down according to the rule
