Answer:

309.33π yd³

Step-by-step explanation:

We can subtract the volume of the sphere from the volume of the cone, but we'd like to point out that said difference is irrelevant to the problem. The sphere does not fit into the cone. We cannot tell exactly how the composite figure is constructed.

Cone volume is ...

V = 1/3πr²h

V = 1/3π(10 yd)²(23 yd) = 2300π/3 yd³

Sphere volume is ...

V = 4/3πr³ = 4/3π(7 yd)³ = 1372π/3 yd³

The difference between the cone volume and the sphere volume is ...

(2300 -1372)π/3 yd³ ≈ 309.33π yd³

The surface area of a rectangular prism is 208 cm2. Two of the dimensions are 2cm and 10cm. Find the measure of the other dimens

aliina [53]

Answer:

7 cm

Step-by-step explanation:

SA = 208 cm^2

SA= 2*a*b + 2*a*c + 2*b*c

where:

a= first dimension = 2 cm

b= second dimension = 10 cm

c= third dimension

so we have:

208= 2*2*10 + 2*2*c + 2*10*c

208= 40 + 4c + 20c

208-40= 24c

168=24c

c =168/24

c = 7cm = third dimension

A car dealer acquires a used car for $14,000, with terms FOB shipping point. compute total inventory costs assigned to the used

Artyom0805 [142]

Given:

A car dealer acquires a used car for $14,000, with terms FOB shipping point.

Transportation cost = $100

Shipping insurance = $120

Car import duties = $970

To find:

The total inventory costs assigned to the used car.

Solution:

We know that,

Inventory costs = Value of used car + Transportation cost + Shipping insurance + Car import duties

Inventory costs = $14,000 + $100 + $120 + $970

Inventory costs = $15,190

Therefore, total inventory costs assigned to the used car is $15,190.

B is the midpoint of AC and D is the mid point of CE solve for x given BD=3x + 5 and AE= 4x+20

Elena L [17]

Answer:triangle BCD is similar to triangle ACE (side, angle C, side)

AC = 2 BC

therefore AE = 2 BD

therefore

4x+20 = 2 (3x+5) solve that
