Answer:

it would be r/8 = 4 , and the other answer 32

Step-by-step explanation:

because the teacher divides the ropes among 8 students so r/8 because you don't know the amount of ropes therefore it would be a variable

you multiply 8×4=32 so 32/8= 4

Advertising A bank manager wants to encourage new customers to open accounts with principals of

schepotkina [342]

Answer:

The poster say, "Open an account of $3,500 and earn at least $10 interest in 1 month!" is correct

Step-by-step explanation:

Given, A bank manager wants to encourage new customers to open accounts with principals of at least $3,500.

He decides to make a poster advertising a simple interest rate of 4.8%.

We have to find what must the principal be if the bank manager also wants to advertise that one can earn $10 the first month

We know that, banks offer simple interest

In our problem, simple interest = $10, rate = 4.8%, time = 1 month

Let us see Can the poster correctly say, "Open an account of $3,500 and earn at least $10 interest in 1 month!"?

So now, in our problem, amount = $3500, rate = 4.8% and time = 1 month =

So, the statement is correct.

Hence, amount to be invested is $2500 and poster says correctly.

which equation and ordered pair represent the correct vertex form and vertex for j(x) = x^2 - 12 x +7?

Aliun [14]

Answer:

see explanation

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

Given the equation in standard form : ax² + bx + c : a ≠ 0

then the x-coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

j(x) = x² - 12x + 7 is in standard form

with a = 1, b = - 12 and c = 7, hence

$x_{vertex}$ = - $\frac{-12}{2}$ = 6

substitute x = 6 into j(x) for y- coordinate

y = 6² - 12(6) + 7 = 36 - 72 + 7 = - 29

vertex = (6, - 29 ) and

j(x) = (x - 6)² - 29 ← equation in vertex form

The volume of a right cylinder is 155.4 ft. 3 The radius is 3 ft. Determine the height of the cylinder.

BigorU [14]

Answer:

The height is approximately 5.4961507

Step-by-step explanation:

The volume of a right cylinder is $v=$ π · r² · h, where r is the radius and h is the height.

We know the radius and volume. We can figure out the height like so:

$v= pi * r^2 * h\\\\\frac{v}{pi * r^2} = \frac{pi * r^2 * h}{pi * r^2}\\\\\frac{v}{pi * r^2} = h$

Now, we just substitute the known values in for their corresponding variables:

$\frac{155.4}{3.1415927 (approx.) * (3)^2} = h\\\\\frac{155.4}{3.1415927 (approx.) * 9} = h\\\\\frac{155.4}{28.2743339 (approx.)} = h\\\\5.4961507 = h$

The height of the cylinder is approximately 5.4961507
