Answer:

(252π + 20) cm²

Step-by-step explanation:

The surface area of the resulting solid = curved surface area of the cylinder + area of 1 base of the cylinder + 2(slant height of the cone)

✔️Curved surface area of cylinder = 2πrh

r = ½(12) = 6 cm

h = 18 cm

C.S.A = 2*π*6*18 = 216π cm²

✔️Area of 1 base = πr²

r = ½(12) = 6 cm

Area = π*6²

Area = 36π

✔️Slant height of the cone = 10 cm

✅The surface area of the resulting solid = 216π + 36π + 2(10)

= (252π + 20) cm²

Complete question is;

The city just assigned a second garbage truck to empty the bins in Kat’s neighborhood on trash day. The crew from the first garbage truck used to empty all the bins by themselves in 5 hours. In their training, it took the crew from the second garbage truck 8 hours to empty all the bins. When the two crews start working together, what part of all the garbage bins will the first garbage truck empty? To the nearest tenth, the first garbage truck will empty about of all the bins.

Answer:

Part of all bins first garbage truck will empty = 0.6

Step-by-step explanation:

Let the total number of bins emptied be denoted by n.

We are told that the crew from the first garbage truck empties all the bins in 5 hours. Thus

Work rate = (n/5) bins/hr

We are told the second garbage truck empties in 8 hours. Thus;

Work rate = (n/8) bins/hr

When both garbage trucks work together, the total amount of time spent will be denoted by x. Thus;

((n/5) + (n/8))x = n

Divide through by n to get;

x/5 + x/8 = 1

Multiply through by 40 to gwt;

8x + 5x = 40

13x = 40

x = 40/13 hrs

To find the part of all the garbage bins the first garbage truck empty when they work together, we will simply multiply the value of x by the work rate of the first garbage truck. Thus;

Part = (n/5) × (40/13)

Part = (40/65)n = 0.615 of n

To the nearest tenth gives 0.6 of n

Answer:

a= 17√3/ 2 or a≈14.72

Step-by-step explanation:

c = 17 and is the side opposite to the angle C

c=AB =17

a= BC because is the side opposite to angle A

sin 60° = opp./hyp = BC / AB = BC/17

sin 60° = BC /17  multiply both sides by 17

BC = 17* sin 60 = 17√3/2 ≈14.72

Answer:

5/28

Step-by-step explanation:

P(oj, then grape) = 2/8 x 5/7 = 10/56 = 5/28

The probability of pulling out a bottle of orange juice and then a bottle of grape juice is 5/28.

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favorable outcomes / Number of sample

An ice chest contains 2 bottles of orange juice, 5 bottles of grape juice, and 1 bottle of apple juice, all buried in ice.

The probability of pulling out a bottle of orange juice and then a bottle of grape juice is calculated as below:-

Probability = Number of favorable outcomes / Number of sample

P(orange , then grape) = 2/8 x 5/7 = 10/56 = 5/28

Therefore, the probability of pulling out a bottle of orange juice and then a bottle of grape juice is 5/28.

Answer:

  -4arccos(x^(1/4)) +C

Step-by-step explanation:

My machine solver gives an answer that reduces to the expression ...

  -4arccos(x^(1/4)) +C

__

We know that ...

  (d/dx)arccos(x) = -1/√(1-x²)

If you let u = x^(1/4), then you can make the integrand look something like ...

  4 du/√(1 -u²)

which is what you need to get to the arccos function.

this is how i solved it hopefully its correct

Answer:

[tex]Y=\frac{c}{a}-\frac{b}{a}[/tex]

Step-by-step explanation:

Answer:

y=c+b/a (The a is under c+b)

Step-by-step explanation:

Add the b over to c.

ay=c+b

Now divide both sides by a, which will remove the a from y.

y=c+b/a

Ryan runs a total of 94.5 miles over the course of 18 days.

Speed is the ratio of the given distance and time.

It shows how fast an object is moving at a given time.

The formula is Distance / Time.

We can find the distance or time when the required values are given using this formula.

We have,

We can approach this problem by using arithmetic progression.

The first term is 1.5 miles, and the common difference is 0.3 miles.

So,

The nth term is given by:

an = a1 + (n-1)d

where a1 is the first term, d is the common difference, and n is the number of days.

We want to find the total distance Ryan runs over 18 days, which is the sum of the first 18 terms of the arithmetic progression:

S18 = (n/2) (a1 + an)

where n is the number of terms and a1 and an are the first and last terms, respectively.

Substituting the values we have:

a1 = 1.5 miles

d = 0.3 miles

n = 18

an = 1.5 + (18-1)0.3 = 6 miles

S18 = (18/2)(1.5 + 6) = 94.5 miles

Therefore,

Ryan runs a total of 94.5 miles over the course of 18 days.

Answer:

The total distance traveled by the toy car is 14 m

Step-by-step explanation:

Given;

initial velocity of the car, u = 0

final velocity of the car, v = 4 m/s

time of motion, t₁ = 3 s

constant deceleration of the car, -a = 0.5 m/s²

time of motion, t₂ = 4 s

The total distance traveled by the car, is the area of triangle ABC (check the image uploaded).

Hi there, so we know that all triangles add up to 180 degrees so we will take 38 and add it with 25 to get 63 then we subtract 180 by 63 to get 117 which is your awnser!!
