Answer:

320,000 dm

Step-by-step explanation:

A decimetre is equivalent to 10 cm or \(\frac{1}{10}\)m. We can use this to work out the answer.

1km is equal to 1,000m or 10,000dm (using the second option above).

This means for 32km, it should be 32×10,000dm.

This gives 320,000 dm.

Answer:

Step-by-step explanation:

Sandy covers a distance of 211 63/78 km in 212 hours.

If Sandy covers 312 km in one hour,

then in 2 hours he will cover 2 x 312 = 624 km, in 3 hours he will cover 3 x 312 = 936 km, and so on.

In 212 hours, he will cover 212 x 312 = 66084 km.

To write this as a mixed fraction,

we can divide 66084 by 312 to get:

66084 ÷ 312 = 211 + 252/312

So Sandy covers 66084 km in 212 hours, which can be written as the mixed fraction 211 252/312.

We can simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 4:

211 252/312 = 211 63/78

So Sandy covers a distance of 211 63/78 km in 212 hours.

Answer: 1/2x + 1/3

Step-by-step explanation:

Given:

1/4(x) + 3/4(x) - 1/2(x) + 1 - 2/3

Step 1: Combine like terms

1/4(x) and 3/4(x) have a common denominator of 4.  This means that you can add them together.

1/4(x) + 3/4(x) = 4/4(x) = x

Step 2: Find the common denominator of x in step 1 and combine like terms  

x - 1/2(x) = 2/2(x) - 1/2(x)

Now that we have the common denominator of x, we can combine like terms.  Its the same as adding or subtracting fractions without a variable.  In this case, you must subtract 1/2(x) from 2/2(x).

2/2(x) - 1/2(x) = 1/2(x)

Step 3: Find the common denominator of the constants and combine like terms

1 - 2/3 = 3/3 - 2/3

Now combine like terms.  Simply subtract 2/3 from 3/3.

3/3 - 2/3 = 1/3

Step 4: Write the simplified equation

1/2(x) + 1/3

This is the answer

Answer:

26 - 11 = 15

Step-by-step explanation:

The value of x must be between -18 and -6. The solution has been obtained using Triangle inequality theorem.

What is Triangle inequality theorem?

The triangle inequality theorem explains how a triangle's three sides interact with one another. This theorem states that the sum of the lengths of any triangle's two sides is always greater than the length of the triangle's third side. In other words, the shortest distance between any two different points is always a straight line, according to this theorem.

We are given three sides of a triangle as 8, 6 and x+20

Using Triangle inequality theorem,

⇒8+6 > x+20

⇒14 > x+20

⇒-6 > x

Also,

⇒x+20+6 > 8

⇒x+26 > 8

⇒x > -18

Also,

⇒x+20+8 > 6

⇒x+28 > 6

⇒x > -22

From the above explanation it can be concluded that x is less than -6 but greater than -22 and -18.

This means that x must lie between -18 and -6.

Hence, the value of x must be between -18 and -6.

Answer: 72.97 Minutes

Step-by-step explanation: We have two cars, A and B, traveling along a straight road. Car A is moving at a constant speed of 77.0 km/h, while car B is moving at a constant speed of 114 km/h. At the starting point (t=0), car B is 45.0 km behind car A.

To figure out how long it takes for car B to catch up and overtake car A, we need to consider their relative speeds. The relative speed is the difference between the speed of car B and the speed of car A.

Relative speed = Speed of car B - Speed of car A

Relative speed = 114 km/h - 77.0 km/h

Relative speed = 37.0 km/h

So, car B is moving 37.0 km/h faster than car A. Now, we need to determine the time it takes for car B to cover the initial distance between them, which is 45.0 km.

To calculate time, we use the formula: Time = Distance / Speed. In this case, the distance is 45.0 km, and the speed is the relative speed of 37.0 km/h.

Time = 45.0 km / 37.0 km/h ≈ 1.2162 hours

Now, let's convert the time to minutes by multiplying it by 60 (since there are 60 minutes in an hour).

Time = 1.2162 hours * 60 minutes/hour ≈ 72.97 minutes

Therefore, it takes approximately 1.2162 hours or 72.97 minutes for car B to catch up and overtake car A.

no of students in each van = 6

no. of students in each bus = 42

This can be solved by equation solving.

An equation is a formula in mathematics that uses the equals sign (=) to represent the equality of two expressions.

Given that,

Let, x = no. of students in van

y = no. of students in bus

According to the question:

5x + 4y = 198 .............. (1)

4x + 3y = 150 ............. (2)

Multiply equation (1) by 4 and equation (2) by 5 we get:

20x + 16y = 792

20x + 15y = 750

now after subtractions:

or, y = 42

putting the value of y in equation (1) we get:

5x + 4(42) = 198

or, 5x + 168 = 198

or, 5x = 30

or, x = 6

Thus, no of students in each van = 6

no. of students in each bus = 42

The shortcut of the Converse of the Isosceles Triangle Conjecture can be used to prove the above statement.

Given: m∠a = 65˚; m∠f = 65˚

Since, both angles are equal, we can prove the following statement by using the Converse of the Isosceles Triangle Conjecture.

Thus, the correct option is: Shortcut of the Converse of the Isosceles Triangle Conjecture which states that if two angles of a triangle are congruent, then the sides opposite those angles are congruent.

Hence, option 1 is correct.

In this case, we can see that in triangle ABC, angles B and C are congruent to each other.

That is, m∠b = 65˚ and m∠c = 65˚, and as per the Converse of the Isosceles Triangle Conjecture, the sides opposite to angles B and C, that is, AB and AC must be congruent to each other.

The correct answer is option b. 15.77%. The annual discount rate, also known as the discount rate or the rate of return, can be calculated using the present value formula.

Given that a cash flow of £52 million in 5 years' time is currently valued at £25 million, we can use this information to solve for the discount rate.

The present value formula is given by PV = CF / (1 + r)^n, where PV is the present value, CF is the cash flow, r is the discount rate, and n is the number of years.

In this case, we have PV = £25 million, CF = £52 million, and n = 5. Substituting these values into the formula, we can solve for r:

£25 million = £52 million / (1 + r)^5.

Dividing both sides by £52 million and taking the fifth root, we have:

(1 + r)^5 = 25/52.

Taking the fifth root of both sides, we get:

1 + r = (25/52)^(1/5).

Subtracting 1 from both sides, we obtain:

r = (25/52)^(1/5) - 1.

Calculating this value, we find that r is approximately 0.1577, or 15.77%. Therefore, the annual discount rate is approximately 15.77%, corresponding to option b.

Answer:

$8.72

Step-by-step explanation:

Since the tax rate is 9% of the lunch cost, the tax for this lunch is .72 dollars since 9% of 8 is 0.72(see math below). You add the 0.72 to 8 and the total cost is $8.72.

8 x (9/100) = tax

8 x 0.09 = 0.72

8+0.72 = $8.72

Let's denote the consecutive even integers representing the number of pennies, dimes, nickels, and quarters as 2n, 2n+2, 2n+4, and 2n+6, respectively.

We know that 100 pennies make $1, 10 dimes make $1, 20 nickels make $1, and 4 quarters make $1.

To find the number of coins, we need to set up an equation based on the given information:

2n + 10(2n+2) + 20(2n+4) + 4(2n+6) = 682 (converted $6.82 to cents)

Simplifying the equation:

2n + 20n + 20 + 40n + 80 + 8n + 24 = 682

70n + 124 = 682

70n = 558

n = 8

Now, we substitute the value of n back into the expression for the number of coins:

2n = 2(8) = 16

2n+2 = 2(8)+2 = 18

2n+4 = 2(8)+4 = 20

2n+6 = 2(8)+6 = 22

Therefore, Michelle has 16 pennies, 18 dimes, 20 nickels, and 22 quarters. In total, she has 16 + 18 + 20 + 22 = 76 coins.

Answer:

60 minutes

Step-by-step explanation:

Latitude and longitude are measuring lines used for locating places on the surface of the Earth. They are angular measurements, expressed as degrees of a circle. A full circle contains 360°. Each degree can be divided into 60 minutes, and each minute is divided into 60 seconds.

One degree of latitude is equal to approximately 60 nautical miles or 69 statute miles. Since a minute of latitude is one-sixtieth of a degree, it follows that one degree of latitude is equal to 60 minutes.

This means that there are 60 nautical miles or 69 statute miles between two points that differ by one minute of latitude.

The minute of latitude is a widely used unit for measuring distances on Earth, particularly in navigation and aviation. It allows for precise calculations and is crucial for determining positions accurately. Understanding the relationship between degrees of latitude and minutes helps in determining distances, estimating travel times, and ensuring accurate navigation across the globe.
