The perimeter of a rectangular plot of land
is 46.4m. If the width of the plot is 7.4m.
what is its length?
A. 15.8m
B. 8.8m
C. 13.6m
D. 9.2 m​

Answers

Answer:

A. 15.8

Step-by-step explanation:

First the perimeter of a rectangle = 2 (L +W)

So; 46.4 = 2(L + 7.4)

46.4 = 2L + 14.8

2L = 46.4 - 14.8

2L = 31.6

L =15.8

A market research survey has 15 questions and will be sent to 500 people. What is the total cost to conduct the survey if it has a $1,000 base fee plus $5 per question and $2 per person surveyed?

Answers

Answer:

Total cost to conduct survey = $2075

Step-by-step explanation:

Given that:

Number of questions on survey = 15

Number of people = 500

Base fee = $1000

Per question charge = $5

Per person surveyed = $2

Let,

q be the number of questions

p be the number of people

Total cost = Base fee + 5q + 2p

Total cost = 1000 + 5(15) + 2(500)

Total cost = 1000 + 75 + 1000

Total cost = $2075

Hence,

Total cost to conduct survey = $2075

Answer:

h=(3v)/(pi r^2)

Step-by-step explanation:

you simply have to move everything to one side.

Answer:

h = [tex]\frac{3V}{\pi r^2}[/tex]

Step-by-step explanation:

Given

V = [tex]\frac{1}{3}[/tex]πr²h ( multiply both sides by 3 to clear the fraction )

3V = πr²h ( isolate h by dividing both sides by πr² )

[tex]\frac{3V}{\pi r^2}[/tex] = h

Answers

Answer:

Step-by-step explanation:

From the picture attached,

a). Triangle in the figure is ΔBCF

b). Since, [tex]L_1[/tex] and [tex]L_2[/tex] are the parallel lines and m is a transversal line,

   m∠FBC = m∠BFG [Alternate interior angles]

   Since,  [tex]L_1[/tex] and [tex]L_2[/tex] are the parallel lines and n is a transversal line,

   m∠BCF = m∠CFE [Alternate interior angles]

   By triangle sum theorem in ΔBCF

   m∠FBC + m∠BCF + m∠BFC = 180°

   From the properties given above,

   m∠BFG + m∠CFE + m∠BFC = 180°

   m∠GFE = 180°

Therefore, angle GFE is the straight angle that will be useful in proving that the sum of the measures of the interior angles of the triangle is 180°.

a) The foxes distance starts decreasing from 3 seconds to 6 seconds, since the line is coming down as time increases.
b) the fox is still from 2 seconds to 3 seconds, since the line is flat.
c) let’s look at the slope of the four intervals.

From 1 to 2, the distance increases to 4. The slope is 4/2 = 2.
From 2 to 3, the distance doesn’t change. The slope is 0.
From 3 to 5, the distance decreases to 3. The slope is -1/2.
From 5 to 6, the distance decreases to 0. The slope is -3, which is the greatest magnitude, therefore the fox is moving fastest.

Subtract (2x - 2y) from the sum of (10x - 2y) and (-3y)

Answers

(10x-2y)+(-3y)= 10x-5y
(10x-5y)-(2x-2y)= 8x-3y

ANSWER: 8x-3y

Subtract (2x - 2y) from the sum of (10x - 2y) and (-3y) is 8x -3y.

What is subtraction?

Subtraction is a mathematic operation. Which is used to remove terms or objects in an expression.

The sum of  (10x - 2y) and (-3y).

(10x - 2y) + (-3y),

= 10x -2y -3y

= 10x -5y

Subtract (2x - 2y) from the sum of (10x - 2y) and (-3y),

= 10x -5y - (2x - 2y)

= 8x -3y

Therefore, the expression is 8x -3y.

what is y=6x^2 +96x +388 in vertex form?
please show work

Answers

Answer:

y = 6(x + 8)² + 4

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Using the method of completing the square.

y = 6x² + 96x + 388

The coefficient of the x² term must be 1, so

factor out 6 from 6x² + 96x

y = 6(x² + 16x ) + 388

To complete the square

add/subtract (half the coefficient of the x- term)² to x² + 16x

y = 6(x² + 2(8)x + 64 - 64) + 388

  = 6(x + 8)² - 384 + 388

y = 6(x + 8)² + 4 ← in vertex form
