The only way the coach can guarantee that he is about to paint a rectangle using only a tape measure is by measuring opposite sides of the field and be assured that they are equal.

This is because the opposite sides of a rectangle are always the same, else it is not a rectangle.

$4,221.00 for online and 6,210.00 for the instore

Step-by-step explanation:

Calculation:

First, converting R percent to r a decimal

r = R/100 = 4.2%/100 = 0.042 per year.

Solving our equation:

A = 6700(1 + (0.042 × 15)) = 10921

A = $10,921.00

The total amount accrued, principal plus interest, from simple interest on a principal of $6,700.00 at a rate of 4.2% per year for 15 years is $10,921.00.

Calculation:

First, converting R percent to r a decimal

r = R/100 = 6.9%/100 = 0.069 per year.

Solving our equation:

A = 6000(1 + (0.069 × 15)) = 12210

A = $12,210.00

The total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 6.9% per year for 15 years is $12,210.00.

Answer:

-3x+42+9x=6x+42

0x=0

x=0

Step-by-step explanation:

there is no solution

Answer:

infinitely many solutions

Step-by-step explanation:

Given

- 3(x - 14) + 9x = 6x + 42 ← distribute and simplify left side

- 3x + 42 + 9x = 6x + 42

6x + 42 = 6x + 42

Since the equation is the same on both sides, then any real value of x is a solution.

That is has infinite solutions

I just got this correct on the test

The linear relationship between c and s is c = 20s and on the graph paper, it will be a line.

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

We have:

Mrs. Robertson is preparing manipulatives for her math class. Each student will receive a plastic cup with 20 two-color counters.

c is the total number of two-color counters

s is the number of students

The linear relationship becomes:

c = 20s

Thus, the linear relationship between c and s is c = 20s and on the graph paper, it will be a line.

Answer:

2500

Step-by-step explanation:

solve brackets first

30+20=50

now multiply 50 × 50 (out of the brackets )

50 × 50 = 2500

Answer:

50 homes

Step-by-step explanation:

Given that:

Total Number of homes = 750

Years at which home is listed = 6

Thus average listing per year = (total number of homes / years)

Average listing per year = 750 / 6

Average listing per year = 125 homes

If 40% of homes in the neighborhood can be listed :

0.4 * 125

= 50 homes

Sales associate should obtain listing of 50 homes

Given : Total 750 houses with listing tendencies every six years.

So, average annual houses listing = 750 / 6 = 125

Also, listings = 40%

Hence, sales associate obtain 40% of 125 = 50

  Volume of a cone =  (1/3) pi x r^2 x h

Volume of a cylinder =  pi x r^2 x h

Volume of the cylinder = pi x 2^2 x 3 = 37.68 cubic inches

Now set the volume for the cone to the volume of the cylinder and solve for the height.

37.68 = (1/3) x pi x r^2 x h

37.68 = (1/3) x pi x 3^2 x h

37.68 = (1/3) x pi x 9 x h

37.68 = 9.42 x h

h = 37.68 / 9.42

h = 4

The height of the cone is 4 cm.

Answer:

d

Step-by-step explanation:

If chord BC passes through the centre then it is a diameter . then

∠ BAC is the angle in a semicircle and x = 90°

y = 180° - (90 + 25) ← angle sum in a triangle

y = 180° - 115° = 65°

Thus

x = 90°, y = 65° → d

In this exercise we have to use the knowledge of triangles inscribed in a circle, in this way it will be possible to calculate the angles, then:

Letter D

Knowing that it is a triangle inscribed in a circle, in this way we can describe it as:

So:

[tex]y = 180 - 115 = 65\\ x = 90\\ y = 65 [/tex]

The slope is 2

Step-by-step explanation:

Given

x   y

2    3

5    9

Required

Determine the slope

First, we have:

[tex](x_1,y_1) = (2,3)[/tex]

[tex](x_2,y_2) = (5,9)[/tex]

The slope is then calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

This gives:

[tex]m = \frac{9-3}{5-2}[/tex]

[tex]m = \frac{6}{3}[/tex]

[tex]m =2[/tex]

Hence, the slope is 2.

Answer:

C

Step-by-step explanation:

Answer:

y = -3x - 2

Step-by-step explanation:

slope (m) = (-8 - -5) / (2 - 1)   ... difference of y/difference of x

m = -3

y = mx + b

y = -3x + b

for (3,-11)    b = y + 3x = -11 + 3x3 = -2

equation: y = -3x - 2

Answer:

A direct variation is when x and y (or f(x) and x) are directly proportional to each other... For example, if you have a chart that says x and y, and in the x column is 1, 2 and 3, and the y column says 2, 4 and 6... then you know it's proportional because for each x, y increases by 2

Answer:

n < - 3 or n > - 2

Step-by-step explanation:

Inequalities of the type | x | > a , have solutions of the form

x < - a or x > a

Then

2n + 5 < - 1 or 2n + 5 > 1

Solve both inequalities

2n + 5 < - 1 ( subtract 5 from both sides )

2n < - 6 ( divide both sides by 2 )

n < - 3

OR

2n + 5 > 1 ( subtract 5 from both sides )

2n > - 4 ( divide both sides by 2 )

n > - 2

Solution is n < - 3 or n > - 2

Step-by-step explanation:

Notice that in n(n + 1)(n + 2)(n + 3):

Exactly 2 of them are multiples of 2,

At least 1 of them is a multiple of 3, and

At least 1 of them is a multiple of 4.

Since one of the multiples of 2 is already counted in the multiple of 4 we can ignore it.

Hence we have 2 * 3 * 4 = 24.

The greater positive integer that must be a factor is 24.

Answer:$2800

Step-by-step explanation: Lets first figure out how much money a box of candy bars is worth. We know that each candy bar is worth $5 and that there are 7 candy bars per box. We can multiply 7*5 to figure out that each box is worth $35.

Now lets figure out how many boxes can be sold each day. Each student can sell two boxes a day. 5 students selling 2 boxes each is 5*2= 10 boxes total sold a day.

Now finally we use what we found to figure out the amount of money made per day. We know that there are 10 boxes being sold and that each box makes them $35. We just multiply 10 boxes by $35 to get $350 dollars each day.

Since they sell for 8 days we just multiply 8*$350 to get $2800.

Answer:

c) x=4

Step-by-step explanation:

Answer:

the equation to use would be D (255-20(5) = ?). To solve, first multiply 20 and 5 and you would get 100 so the equation would be 255 - 100 = ? Then you would subtract 100 from the 255 to get $155 left. To solve for 7 weeks you would replace the 5 in the equation with 7 so your equation would be 255 - 20(7) = ? Next you would multiply 20 and 7 to get 140. the equation would then be 255 - 140 = ? Subtract 140 from 255 and you would get 115. So after 7 weeks she would have $115 left in her account.
