RBT/Z + H/K = M, Solve for H

irakobra [83]

Answer:

H = MK - RBTK/Z

Step-by-step explanation:

Given

RBT/Z + H/K = M

Solving for H

RBT/Z + H/K = M
K×RBT/Z + K×H/K = K×M ⇒ multiplying all terms by K to clear fraction
RBTK/Z + H = MK

RBTK/Z + H - RBTK/Z= MK - RBTK/Z ⇒ subtracting RBTK/Z from both sides

H = MK - RBTK/Z

Hey guys i need help plz will give brainlist

Step-by-step explanation:

Effective resistance in the 30Ω and 40Ω parallel circuit = 1 / (1/30 + 1/40) = 120/7 Ω.

20Ω + 10Ω = 30Ω

Effective resistance in the 50Ω and (20Ω + 10Ω) parallel circuit = 1 / (1/50 + 1/30) = 75/4 Ω.

Now we can add the resistances up:

Effective resistance for circuit

= 120/7 Ω + 75/4 Ω = 1005/28 Ω.

Hence I = V / R

= 9.0V / (1005/28 Ω) = 0.25A. (2s.f.)

PLEASE HELP HOW DO I TRANSLATE IT TO A PROPORTION!!

Answer:

See below.

Step-by-step explanation:

A proportion is setting two ratios equal to each other.

Look at the info you are given for price in $ and area in sq ft:

$385 for 70 sq ft

That allows you to write a ratio. The ratio of dollars to square feet is

385/70 (notice it's dollars divided by sq ft)

Now you look at the part of the problem that has an unknown, and you set up the same type of ratio (dollars to sq ft) using x for the unknown.

x dollars to 200 sq ft

The ratio is

x/200 (notice that, again, it's dollars divided by sq ft)

In both cases the ratios are dollars to sq ft.

To set up a proportion, you just set the ratios equal to each other.

385/70 = x/200

Now we solve the proportion. We can cross multiply.

385/70 = x/200

70x = 385 * 200

70x = 77,000

x = 1100

They would charge $1100 to install 200 sq ft of tile.

The unit price is obtained by dividing a cost by the corresponding area in sq ft. you can use either ratio.

unit price = ($385)/(70 sq ft) = $5.5/sq ft

($1100/200 sq ft also works since it is also equal to $5.5/sq ft)

what is the maximum height of the T-shirt after being fired from the cannon? round to the nearest tenth. Will the fans sitting i

Pie

$h(t)=-16t^2+88t+5$

Based on the given trajectory, the leading numerical coefficient is a negative number, hence, the graph of this function is a parabola opening downwards.

In a parabola opening downwards, the maximum value is the vertex of the parabola. So, in order to determine the maximum height, let's solve for the vertex of the parabola. The formula is:

$t=-\frac{b}{2a}$

where in the quadratic function is in the form of at² + bt + c = 0.

So, in the given trajectory function, a = -16, b = 88, and c = 5. Let's replace the variables in the formula above with their corresponding numerical value.

$t=-\frac{88}{2(-16)}$

Then, solve.

$t=-\frac{88}{(-32)}\Rightarrow t=2.75$

Therefore, at t = 2.75 seconds, the t-shirt reached its maximum height.

So, to determine the maximum height, replaced "t" in the trajectory function with 2.75.

$h(2.75)=-16(2.75^)^2+88(2.75)+5$ $h(2.75)=-121+242+5$ $h(2.75)=126$

Hence, after 2.75 seconds, the t-shirt reached its maximum height which is 126 feet.

Since the maximum height of the t-shirt is 126 feet, then yes, there is a chance that the fans sitting in the bleachers 90ft above the field will catch a T-shirt.
