A traffic cone with a height of 20 in. is ideal for traffic control. Find the lateral area of a cone with a height of 20 in. and a diameter of 12 in. Round the answer to the nearest whole number.​

Answers

The lateral area of the cone is 394 square inches

How to determine the lateral area

The formula for lateral area of a cone is expressed as;

Lateral area = πr √h² + r²

Given that;

height = 20 inDiameter = 12 in, radius = 12/ 2 = 6 in

Substitute the values into the formula

Lateral area = 3. 142(6) √20² + 6²

Lateral area = 18. 85 √436

Lateral area = 18. 85 × 20. 8

Lateral area = 394 square inches

Thus, the lateral area of the traffic cone is 394 square inches

A robot can complete 7 tasks in 4 5 hour. Each task takes the same amount of time. a. How long does it take the robot to complete one​ task? b. How many tasks can the robot complete in one​ hour?

Answers

a. It takes the robot 4/35 hour to complete one tasks

b. The number of tasks the robot can complete in one hour is 8 3/4 tasks

Proportion

From the question, we are to determine how long it takes the robot to complete one task

From the given information,

A robot can complete 7 tasks in 4/5 hour

If the robot can complete 7 tasks in 4/5 hour

Then,

The robot will complete 1 task in 4/5 ÷ 7 hour

4/5 ÷ 7

= 4/5 × 1/7

= 4/35  

Hence, it takes the robot 4/35 hour to complete one tasks

b.

Let the number of tasks the robot can complete in one hour be x

If the robot can complete 7 tasks in 4/5 hour

Then,

The robot will complete x tasks in 1 hour

4/5 × x = 7 × 1

4/5 × x = 7

4 × x = 7 × 5

4x = 35

x = 35/4

x = 8 3/4

Hence, the number of tasks the robot can complete in one hour is 8 3/4 tasks

Su mei is looking at online classified ads. she finds a used cell phone for US$99 plus US$30 for shipping. The same cell phone cost C$199 new at a local store. a) what is the total cost of the used cell phone in canadian dollars. b) Do you think Su Mei should buy the cell phone online why

Answers

The total cost of the used cell phone in Canadian dollars is C$130.16.

Su Mei should buy the used cell phone because it is cheaper than the new cell phone.

Which phone should Su Mei buy?

The exchange rate is the rate at which one unit of a currency is exchanged for another currency. For example, if the exchange rate of the US dollar and the Canadian dollars is 1.00903. It means that 1 unit of the US dollar would buy 1.00903 of the Canadian dollars.

The first step is to determine the total cost of the used cell phone in US dollar. The total cost would be the sum of the used cell phone and the shipping cost.

Total cost of the used cell phone = $99 + $30 = $129

The next step is to convert the cost of the used cell phone that is priced in the US dollar to Canadian dollars.

129 x 1.00903 = $130.16

if 8/9 is multiplied by 3/7 will the product be greater than either of the 2 factors

Answers

If 8/9 is multiplied by 3/7 then the product will not be greater than either of the two factors.

According to the question

on multiplying 8/9 by 3/7 we get

=8/9*3/7

=(8*3)/(9*7)

=24/63

=0.38095         ...(i)

On comparing it with two factors,

8/9 = 0.88888         .....(ii)

and

3/7 = 0.42857        ......(iii)

As we can see that on comparing equation (i) with equation (ii) and

equation (i) with equation (iii)    , we get that the product of 8/9 and 3/7 is less than both 8/9 and 3/7 .

Therefore , if 8/9 is multiplied by 3/7 then the product will not be greater than either of the two factors.

Answers

Answer:

x = 1, x = 4

Step-by-step explanation:

First, let x = u^(2/3)

The problem given has a third power and also a 1.5 power. That is just oof! So choosing "u to the 2/3 power" to substitute in for x will make this equation be a straightforward quadratic that you can factor and solve.

see image.

Substitute

x = u^(2/3)

This gives you:

u^2 - 9u + 8 = 0

Factor.

(u - 1)(u - 8) = 0

Solve.

u-1 = 0 and u-8=0

u = 1 and u = 8

Substitute back into

x = u^(2/3)

x = 1^(2/3) and

x = 8^(2/3)

Remember some exponent rules and definitions. The 2 in the 2/3 will square the base number and the 3 (actually 1/3) will cuberoot the base number. See image. Hope this helps.

How long does it take to ride a bicycle 100 miles at each of the following speeds: 5 mph, 10 mph, 15 mph, 20 mph, 25 mph? What is always true about the product speed x time?

Answers

Answer:

5 mph ⇒ 20 h10 mph ⇒ 10 h15 mph ⇒ 6 2/3 h20 mph ⇒ 5 h25 mph ⇒ 4 h

  speed × time = 100 miles

Step-by-step explanation:

The graph shows an inverse relation between speed and time. You want to know what is true about the product of speed and time.

Inversely proportional

Two quantities are inversely proportional when one is proportional to the inverse of the other. A constant of proportionality will be involved. The relation can be written ...

  y = k(1/x)

where x and y are the quantities inversely related, and k is the constant of proportionality.

Application

In the present case, we have a graph of the relation ...

  time = distance/speed

where the distance is 100 miles.

Comparing this to the above inverse proportion relation, we see that "distance" is the constant of proportionality (k):

  time = (100 miles)/speed

The times at various speeds are ...

5 mph ⇒ 20 h10 mph ⇒ 10 h15 mph ⇒ 6 2/3 h20 mph ⇒ 5 h25 mph ⇒ 4 h

Multiplying both sides of this equation by speed, we get ...

  speed × time = speed × (100 miles)/speed

  speed × time = 100 miles

The product of speed and time is always 100 miles in this scenario.

How do I do this? A tennis tournament starts with 117 players. If a player is eliminated after losing three matches, what is the least possible number of matches played when four players are left?

Answers

When only 4 players remain, the fewest number of matches that can be played is 37.

What do we mean by algebra?Algebra is one of the many branches of mathematics. Algebra, in broad terms, is the study of mathematical symbols and the rules for manipulating these symbols in formulas; it is a thread that runs through almost all of mathematics.

Given information:

The total number of players in the tournament is 117.number of players to be eliminated after losing three matches = 1, number of matches played when only four players remain = n

When only four players remain, the smallest number of matches that can be played is calculated as follows:

117 - 1(3n) = 4117 - 3n = 43n = 117 - 43n = 113

Now, divide both sides by 3 as follows:

n = 113/3n = 37.67n ≈ 37 matches

Therefore, when only 4 players remain, the fewest number of matches that can be played is 37.

• c. One cannot tell from the information given.
O d. $60,000
O e. $200,000

Answers

Thus the profit of the manufacturer is 240000$ per month

It is given that a product costing 60 cents per unit to produce had been selling at the average rate of 1,200,000 units per month.

After the product was improved, sales increased to an average of 2,000,000 units per month.

It is also given that the new product cost five percent more to produce.

If the manufacturer's selling price in each instance was 75 cents per unit, We are required to find what was the manufacturer's added profit per month with the newer product.

Cost price is the price which the manufacturer pays for each unit

It is given that the cost price of new version is 5 percent more than the previous one.

Thus, the cost price of each unit of product = 60 cents +5 percent of 60 cents = 60+5/100*60=63 cents

It is also given that selling price of each unit is 75 cents

Profit=selling price- cost price

        = 75-63= 12 cents

Thus, total profit on selling the 2000000 products= 2000000x12cents

Now we know that 100 cents = 1 dollar

Thus the profit in dollars will be = 2000000*12/100=240000

Thus the profit of the manufacturer is 240000$ per month

therefore, we can write, x.y = 51 ... (1)  and x + y = 20 .... (2)

Putting  the value of x from equation (2) in  equation (1) we get,

(20 - y).y = 51
