Final answer:

To convert 27 feet to inches, multiply 27 by the conversion factor of 12 inches per foot, resulting in 324 inches.

Explanation:

To convert 27 feet to inches, we use the unit equivalence that 1 foot = 12 inches. We multiply the number of feet by the conversion factor to get the measurement in inches.

27 feet × 12 inches/foot = 324 inches.

Therefore, 27 feet is equivalent to 324 inches. This is a straightforward application of unit conversion, which is a fundamental skill in mathematics, especially useful for various applications in science, engineering, and everyday calculations.

Answer:

y-4 = (-1/3)(x+1)

Step-by-step explanation:

We need to identify the equation in point slope form.

The standard equation of point slope form is:

(y-y₁) = m (x-x₁)

where m is the slope and x₁ and y₁ are the points

We are given point(4,-1) so,

x₁=4 and y₁=-1

And a perpendicular line: y =3x+5

Which is equal to y = mx+b

where m is slope so, slope m = 3

Since the line is perpendicular, so the slope in negative inverse of actual slope that m = -1/m

i.e, m = -1/3

So, the equation in point slope form is:

y-(-1) = (-1/3)(x-4)

=> y+1 = (-1/3)(x-4)

Answer:

The equation in point slope form for the line perpendicular to y=3x+5 that passes through (4,-1) is y = -⅓x + ⅓

Step-by-step explanation:

Given

Let P represent the lind

Equation of P; y = 3x + 5

Let Q represent the other point.

Coordinates of Q; Q(4,-1)

It is said that the line P is perpendicular to point Q.

So, the first thing to do is to calculate the slope of Q;

Since both lines are perpendicular, then we make use of formula for calculating the condition of perpendicularity

This is given as m1m2 = -1

Where m1 = slope of P

m2 = slope of Q

To get m1;

m1 is the coefficient of x in equation of line P.

So, m1 = 3.

Now we can solve for m2

m1.m2 = -1. ---- make m2 the subject of formula

m2 = -1/m1

Substitute 3 for m1

m2 = -1/3

m2 = -⅓

Recall that the coordinates of Q is 4 and -1.

To calculate the equation of Q; we make use of the following

m = (y - y1)/(x - x1)

Where m = m2 = -⅓

x1 = 4 and y1 = -1

By substituton, we have

-⅓ = (y - (-1))/(x - 4)

-⅓ = (y + 1)/(x - 4) --- multiply both sides by 3(x - 4)

-⅓ * 3(x - 4) = 3(x - 4) * (y + 1)/(x - 4)

-(x - 4) = 3(y + 1)

-x + 4 = 3y + 3 --- make y the subject of formula

3y = -x + 4 - 3

3y = -x + 1 --- divide through by 3

3y/3 = (-x + 1)/3

y = -x/3 + 1/3

y = -⅓x + ⅓

Hence, the equation in point slope form for the line perpendicular to y=3x+5 that passes through (4,-1) is y = -⅓x + ⅓

Answer:

Step-by-step explanation:

Divide using synthetic division, remembering to place a zero to denote the terms x³, x² and x

Since division by (x - 3) then evaluate using h = 3

3 | 1  0  0  0  7

    ↓

    1    3  9  27 81

   ----------------------

    1  3  9  27  88 ← degree 3 polynomial

quotient = x³ + 3x² + 9x + 27 , remainder = 88 → c

Follow below steps:

To divide x^4 + 7 by x - 3, we will use polynomial long division. This process is similar to the long division we use with numbers. Let's perform the division step by step:

Divide the term with the highest power in the dividend (x^4) by the highest power in the divisor (x) to get x^3.

Multiply the entire divisor by x^3 and subtract the result from the dividend.

The subtraction will give a new polynomial. Repeat the process until the degree of the remainder is less than the degree of the divisor, or until no further division can be carried out.

The correct result for the division of x^4 + 7 by x - 3 is option (a): x^3 - 3x^2 - 9x - 27 R 88.

Answer:

[tex]x_1=1+\sqrt{89}\\\\x_2=1-\sqrt{89}[/tex]

Step-by-step explanation:

Apply Distributive property:

[tex](x+7)(x-9)=25\\\\x^2-9x+7x-63=25[/tex]

Add like terms and then add 63 to both sides of the equation:

[tex]x^2-2x-63=25\\\\x^2-2x-63+63=25+63\\\\x^2-2x=88[/tex]

Pick the coefficient of the x term, divide it by 2 and square it:

[tex](\frac{2}{2})^2=1[/tex]

Add it to both sides of the equation:

[tex]x^2-2x+1=88+1[/tex]

Rewriting the left side as a squared binomial, we get:

[tex](x-1)^2=89[/tex]

Apply square root to both sides:

[tex]\sqrt{(x-1)^2}=\±\sqrt{89}\\\\x-1=\±\sqrt{89}[/tex]

And finally we need to add 1 to both sides of the equation. Then we get:

[tex]x-1+1=\±\sqrt{89}+1\\\\x=\±\sqrt{89}+1\\\\\\x_1=1+\sqrt{89}\\\\x_2=1-\sqrt{89}[/tex]

Answer:

16π

Step-by-step explanation:

The surface area of a sphere is:

A = 4πr²

where r is the radius, or half the diameter.

If the diameter is 4 units, then the radius is 2 units:

A = 4π (2)²

A = 16π

The surface area is 16π square units.

[tex]\bf 2x^2+10x+12\implies 2(x^2+5x+6)\implies 2(x+3)(x+2)[/tex]

recall that 3 * 2 = 6, and 3x + 2x = 5x.

Answer:

Step-by-step explanation:

It is a little easier if you take out the two.

2*(x^2 + 5x +6)

The numbers that multiply to 6 and adds to 5 are 3 and 2

2*(x + 3)(x + 2)

So that's how the trinomial factors.

The expression equivalent to given condition is 56wx - 15yz - 29/3.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given expression,

(8w.7x - 5y.3z - 9) - 2/3

since variables are in the product, so their constants are multiplied,

8w.7x  = 56wx

5y.3z  = 15yz

the equation can be written as,

56wx - 15yz - 9 - 2/3

and   - 9 - 2/3 = (-27 - 2)/3 = -29/3

=> 56wx - 15yz - 29/3

Therefore, the equivalent form of the equation is  56wx - 15yz - 29/3.

Answer:

Step-by-step explanation:

From the picture we have:

4w = 3l

If w = 12 ft, then

3l = 4(12)

3l = 48             divide both sides by 3

l = 16 ft

The dimensions of rectangular floor are 4w × (l + w).

Substitute the values of w and l:

4w = 4(12) = 48 ft

l + w = 16 + 12 = 28 ft

The formula of an area of a rectangle:

A = width × length

Substitute:

A = (48)(28) = 1344 ft²

Answer:

$11,340

Step-by-step explanation:

1 month: 630

18 months: 18×630=11,340

Anna pays a total of $11,340 in rent over the course of 18 months by multiplying her monthly rent of $630 by 18.

To find out how much rent Anna pays over the course of 18 months, we need to multiply her monthly rent by the number of months. Anna pays $630 each month, so over 18 months, she would pay:

$630 times 18 = $11,340.

Therefore, Anna pays a total of $11,340 in rent over the course of 18 months.

Answer:

73 m is equal to 730 dm

Step-by-step explanation:

We Need to convert 73 m into dm

We know that 1 meter is equal to 10 decimeter

We are given 73 m. Multiply it with 10 and we will get value in decimeter

73*10

= 730 decimeter

So, 73 m is equal to 730 dm

Answer:

The correct answer would be 730 dm.

Step-by-step explanation:

M is the abbreviation of Meter and dm is an abbreviation of Decimeter. A meter is a unit of length as prescribed by the international system of units. This unit is used to measure the length. Decimeter is the smaller unit of meter. 10 Decimeter makes one meter, which means 1M equals 10DM. So where there are 73 meters, there would be 73 * 10 Decimeters in it. This is shown as below.

73 m = 73 * 10 = 730 DM

Answer:

No; 1,000 will cause him to exceed 1,800.

Step-by-step explanation:

Given,

The consumed calories = 1,600,

Burned calories = 400,

Thus, the remaining calories = 1600 - 400 = 1200

Since, 1,800 calories per day would be like to keep,

Also, 1200 < 1800

Hence, remaining calories is less than the required calories,

And, the calories left to consume for the day = Required calories - remaining calories

= 1800 - 1200

= 600

Therefore, 600 is the viable solution to this problem.

Note : If 1,000 a viable solution to this problem then the required calories will be more than 1800 or exceed 1800.

Step-by-step explanation:

First things first, you can eliminate the bottom left option. The domain 3≤x≤6 means that the graph will only show points greater than or equal to 3 and less than or equal to 6. That option shows x = 2, which is not in this domain.

The symbols on either side of the x are known as ceiling functions. It means that y equals whatever whole number is greater than or equal to than x.

Basically, whatever y is, round it up to the nearest whole number to get x.

A ratio indicates how many times one number contains another.

The numbers in a ratio may be quantities of any kind, such as counts of people or objects, or such as measurements of lengths, weights, time, etc. In most contexts, both numbers are restricted to be positive.

Ratios can be reduced (as fractions are) by dividing each quantity by the common factors of all the quantities. As for fractions, the simplest form is considered that in which the numbers in the ratio are the smallest possible integers.

Thus, the ratio 40:60 is equivalent in meaning to the ratio 2:3, the latter being obtained from the former by dividing both quantities by 20. Mathematically, we write 40:60 = 2:3, or equivalently 40:60∷2:3. The verbal equivalent is "40 is to 60 as 2 is to 3."

Ratios may also be established between incommensurable quantities (quantities whose ratio, as the value of a fraction, amounts to an irrational number). The earliest discovered example, found by the Pythagoreans, is the ratio of the length of the diagonal d to the length of a side s of a square, which is the square root of 2, formally.
