Answer:

14.38

Step-by-step explanation:

1. multiply the 5 packs of pencils times 0.79 each (5x0.79 = 3.95)

2. multiply the 8 packs of pens times 1.19 each (8x1.19=9.52)

3. add the total of pens and pencils together (3.95+9.52=13.44)

4. multiply 13.44 times 7% sales tax (13.44x.07=0.94)

5. add the total plus the sales tax (13.44+0.94=14.38

Two boats leave a dock at the same time. One boat travels south at 32 mi divided by hr32 mi/hr and the other travels east at 60
TEA [102]

Answer: the rate at which the distance between the boats is​ increasing is 68 mph

Step-by-step explanation:

The direction of movement of both boats forms a right angle triangle. The distance travelled due south and due east by both boats represents the legs of the triangle. Their distance apart after t hours represents the hypotenuse of the right angle triangle.

Let x represent the length the shorter leg(south) of the right angle triangle.

Let y represent the length the longer leg(east) of the right angle triangle.

Let z represent the hypotenuse.

Applying Pythagoras theorem

Hypotenuse² = opposite side² + adjacent side²

Therefore

z² = x² + y²

To determine the rate at which the distances are changing, we would differentiate with respect to t. It becomes

2zdz/dt = 2xdx/dt + 2ydy/dt- - - -- - -1

One travels south at 32 mi/h and the other travels east at 60 mi/h. It means that

dx/dt = 32

dy/dt = 60

Distance = speed × time

Since t = 0.5 hour, then

x = 32 × 0.5 = 16 miles

y = 60 × 0.5 = 30 miles

z² = 16² + 30² = 256 + 900

z = √1156

z = 34 miles

Substituting these values into equation 1, it becomes

2 × 34 × dz/dt = (2 × 16 × 32) + 2 × 30 × 60

68dz/dt = 1024 + 3600

68dz/dt = 4624

dz/dt = 4624/68

dz/dt = 68 mph

What is the answer? Please help. Urgent.
MArishka [77]

Given:

A figure that contains a right triangular prism and cuboid.

To find:

The volume of the figure.

Solution:

The dimensions of cuboid are 16 in, 7 in and 3 in.

So, the volume of the cuboid is:

V_1=Length\times Width \times height

V_1=16\times 7 \times 3

V_1=336

The base of the prism is a right angle with base 3 in and height 5 in, and the length of the prism is 6 in. So, the base are of the prism is

B=\dfrac{1}{2}\times Base\times Height

B=\dfrac{1}{2}\times 3\times 5

B=7.5

The volume of a prism is:

V_2=Bh

Where, B is the base area and h is the height of the prism.

V_2=(7.5)(6)

V_2=45

The volume of combined figure is:

V=V_1+V_2

V=336+45

V=381

Therefore, the volume of the figure is 381 cubic in.
