Three friends went to lunch and ordered the special. They had a coupon of $10 off the bill and they spent $35 in all. Write an equation to represent this situation.

Answer:

C. 12/5

Step-by-step explanation:

∆HJK is similar to ∆RST, therefore, the their trigonometric ratios would be equal to each other.

There,

Tan T = Tan K

Tan K = opp/adj

Tan K = 12/5

Therefore,

Tan T = Tan K = 12/5

Tan K = 12/5

Answer:

a. 450 b.  10078.9097

Step-by-step explanation:

a. go with the formula W=FD

F= force

W= work done

D= distance

b. go with the formula F=mgcos(x)

M= mass

G= gravity constant (9.8)

then get to the normal formula of W=FD after getting the Force

Answer:

-10

Step-by-step explanation:

Answer:

So, to find the number we have to subtract 65 from 180 180-65 = 115 So 115 will be added to 65 to get 180.

Step-by-step explanation:

A bucket of paint has spilled on a tile floor. The paint flow can be expressed with the function r(t) = 3t, where t represents time in minutes and r represents how far the paint is spreading.

The flowing paint is creating a circular pattern on the tile. The area of the pattern can be expressed as A(r) = πr2.

Part A: Find the area of the circle of spilled paint as a function of time, or A[r(t)]. Show your work.

Part B: How large is the area of spilled paint after 10 minutes? You may use 3.14 to approximate π in this problem.

Answer:

to differential calculus, because I don't know how to answer this question without

using it.

We're told that Jason's height above the water is  H(t) = -16t² + 16t + 480 .

We can observe many things from this equation:

-- Up is the positive direction; down is the negative direction.

-- The acceleration of gravity is 32 ft/sec² .

-- Jason jumps upward from the cliff, at 16 ft/sec .

-- The cliff is 480-ft above the water.

(This tells us why the question is only concerned with his maximum height,

and then it ends ... 480-ft is one serious cliff, and what happens after the

peak of his arc is too gruesome to contemplate.)

In any case, his vertical velocity is the first derivative, with respect to time,

of his height above the water.

        V = -32 t + 16

At the peak of his arc, where gravity takes over, his velocity changes from

upward to downward, and it's momentarily zero.

                                          0 = -32t + 16

Add  32t  to each side:    32t = 16

Divide each side by  32:      t = 1/2 second

His height at that instant is     H(0.5) = -16(0.5)² + 16(0.5) + 480 =

                                          4-ft above the cliff,  484-ft above the water,

and then he begins falling from that altitude.

The duration of his dive is      484 = 16 t²

                                                  t = √(484/16) = 5.5 seconds

and he hits the water at      V = a t = (32) x (5.5) = 176 ft/sec = exactly 120 mph

Answer: -13

Step-by-step explanation:

1. Isolate x: move 5 to the otherside

=> -2x-6=4*5 => -2x-6=20

2. Move 6 to the otherside: -2x=20+6 => -2x=26

3. Divide both sides by -2

=> x=26/-2 => x=-13

The answer is 3kg

Answer:

[tex]density = mass \div volume \\ 20 = x \div 4 \times 3 \times 5 \\ 20 = x \div 60 \\ 20 \times 60 = x \\ x = 1200 \\ 1200 \div 1000 = 1.2kg[/tex]
