The aircraft A330 flies at an average speed of 600 miles per hour. The expression, 600t gives the distance traveled by the aircraft in t hours. Find the distance traveled by the A330 in 3 hours.

Answer:

An interesting experiment is given. We need to address various questions based on our knowledge of calculus.

Step 2

Part (a)

Time taken for the radius to grow to 2 cm = t1 = r/0.5 = 2/0.5 = 4 hours

Time taken for the radius to become 0 = t2 and the same can be obtained by solving:

r = 2 - √t2 = 0

Hence, t2 = 22 = 4 hours

Hence, the time duration of the entire experiment (from the introduction of the bacteria until its disappearance) = t1 + t2 = 4 + 4 = 8 hours

Step 3

Part (b)

r(t) = 0.5t for 0 ≤ t ≤ 4

and

r(t) = 2 - √(t - 4) for t > 2

Complete question:

Two six-sided dice are rolled (one red one and one green one). Some possibilities are (Red= 1, Green=5) or (Red=2, Green=2) etc.

a)How many total possibilities are there?

For the rest of the questions, we will assume that the dice are fair and that all the possibilities in (a) are equally likely.

b)What is the probability that the sum on the two dice comes out to be 11?

c)What is the probability that the sum on the two dice comes out to be 7?

d)What is the probability that the numbers on the two dice are equal?

Answer:

Kindly check explanation

Step-by-step explanation:

Total probabilities :

Total possible outcomes on each dice = 6

Total probabilities = 6² = 36

b)What is the probability that the sum on the two dice comes out to be 11?

Total required outcome = 2

Total possible outcomes = 36

Probability = required outcome / Total possible outcomes

P(sum on both dice = 11) = 2 / 36 = 1/18

c)What is the probability that the sum on the two dice comes out to be 7?

Required outcome = 6

Possible outcomes = 36

P(obtaining a sum of 7) = 6/36 = 1/6

d)What is the probability that the numbers on the two dice are equal

= required outcome / possible outcomes

Required outcome = 1,1 ; 2,2; 3,3; 4,4 ; 5,5 ; 6,6

= 6/36 = 1/6

Answer:

Volume of the lake = 6.44 × 10¹¹ Litres

Step-by-step explanation:

First, let us unify the units of measurement in the problem by converting the depth from feet to miles

1 mile = 5280 feet

1 foot = 1/5280 miles

∴ 51.0 Feet = 51.0 × (1/5280) miles

= 0.009659 miles

Next, let us calculate the volume of the lake.

Volume = surface area × depth

surface area = 16.0 (mi)²

depth = 0.009659 mi

volume = 16.0 × 0.009659 = 0.15454 (mi)³

Next, since we are asked to report the volume in litres, let us convert from cubic miles to litres

1 cubic mile = 4.168 × 10¹² litres

∴ 0.15454 cubic miles = 4.168 × 10¹² × 0.15454

= 6.44 × 10¹¹ Litres

∴ Volume of the lake = 6.44 × 10¹¹ Litres

The volume of the lake is 6.46×10¹¹ liters.

To get the volume of the lake in liters, we need to calculate the volume in square miles and then convert it to liters.

Please let me know if you have any question

both the father and son worked for 6 hours each.

Let's denote the number of hours that both the father and son worked as "h".

The father charges $12 per hour, so his earnings for h hours of work would be 12h dollars.

The son charges $6 per hour, so his earnings for h hours of work would be 6h dollars.

Since their combined charge for labor was $108, we can set up the equation:

12h + 6h = 108

Combining like terms:

18h = 108

To solve for h, we divide both sides of the equation by 18:

h = 108 / 18

h = 6

Therefore, both the father and son worked for 6 hours each.

There are 0 ones in the number 600 after writing the number in the form of 600 + 00 + 0

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

We have a number:

We can write it as:

600 =       600     +      00    + 0

Number    hundreds   tens    ones

There are 0 ones in the number 600.

Answer:

Salad cost = $4

Sandwiches cost= $6.5

Drinks cist= $2

Step-by-step explanation:

Let salad = x

Sandwiches= y

Drinks= z

2x+2y+z= 23...... equation one

3x+y+3z= 24.5 .... equation two

X= 2z.... equation three

Substituting equation three into equation one and two

2(2z) +2y +z= 23....

3(2z)+y +3z= 24.5....

2y +5z= 23.... equation 4

y + 9z= 24.5...equation 5

Multiplying equation 5 with 2

2y +5z= 23

2y + 18z= 49

Solving simultaneously

13z= 26

Z= 26/13

Z= 2

2y +5z= 23

2y +5(2)= 23

2y= 23-10

2y= 13

Y= 6.5

X= 2z

X=2(2)

X= 4

Salad cost = $4

Sandwiches cost= $6.5

Drinks cist= $2

Answer:

The family will pay 34722 cents more if they take the van

Step-by-step explanation:

Given

Van = 12 miles per gallon

Sedan = 36 miles per gallon

Distance = 2500 miles

Gas = $2.50 per gallon

First, we need to determine the number of gallons that'll be used by both vehicles

This  is done by dividing total distance by number of miles per gallon

[tex]Van = \frac{2500}{12} \ gallon[/tex]

[tex]Sedan = \frac{2500}{36}\ gallon[/tex]

Next, is to multiply this by the cost of gas per gallon;

This gives the total spendable amount on both vehicles

[tex]Van = \frac{2500}{12} * \$2.50[/tex]

[tex]Van = \frac{\$6250}{12}[/tex]

[tex]Van = \$520.833[/tex]

[tex]Sedan = \frac{2500}{36}* \$2.50[/tex]

[tex]Sedan = \frac{\$6250}{36}[/tex]

[tex]Sedan = \$173.611[/tex]

Next is to get the difference between these amounts

[tex]Difference = \$520.833 - \$173.611[/tex]

[tex]Difference = \$347.222[/tex]

Multiply by 100 to convert to cents

[tex]Difference = 347.222 * 100 cents[/tex]

[tex]Difference = 34722.2 \ cents[/tex]

[tex]Difference = 34722\ cents[/tex] (Approximated)

Hence;

The family will pay 34722 cents more if they take the van

x = 3

Step-by-step explanation:

6x + 2x - 5= 19

8x -5 = 19

8x = 24

x = 3

Answer:

x = 3

Step-by-step explanation:

6x + 2x - 5 = 19

Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, combine like terms:

(6x + 2x) - 5 = 19

(8x) - 5 = 19

Next, isolate the variable, x. First, add 5 to both sides:

8x - 5 (+5) = 19 (+5)

8x = 19 + 5

8x = 24

Next, divide 8 from both sides:

(8x)/8 = (24)/8

x = 24/8

x = 3

Answer:

[tex]\frac{511\,\,\sqrt{3} }{99}[/tex]  which is an irrational number

Step-by-step explanation:

Recall that the repeating decimal 0.7373737373... can be written in fraction form as: [tex]\frac{73}{99}[/tex]

Now, let's write the number 147 which is inside the square root in factor form to find if it has some perfect square factors:

[tex]147=7^2\,3[/tex]

384 the next greatest number of tens is 390.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

Note that the tens place is two moves to the right of the decimal point (if it exists).

To determine the greatest number to the nearest ten (nearest 10),

we use the place of the whole number to determine whether the tens place rounds up or stays the same.

The tens place (8) then look at the digit to the right (4):

⇒ 384

The digit to the right (4) is 4 or below. So, we replace it with a 0 (zero) to get 390 as the answer.

So, 384 the next greatest number of tens is 390.
