A jet travels 470 miles in 2 hours. At this rate, how far could the jet fly in 11 hours?

Answers

Answer:

The jet will cover 2585 miles in 11 hours.

Step-by-step explanation:

Given that:

Distance travelled by jet in 2 hours = 470 miles

Speed of jet = [tex]\frac{Distance}{Time}[/tex]

Speed of jet = 470/2

Speed of jet = 235 miles per hour

Time = 11 hours

Distance travelled in 11 hours = Speed * Time

Distance = 235 * 11

Distance = 2585 miles

Hence,

The jet will cover 2585 miles in 11 hours.

[tex]\sqrt{29}[/tex]

Step-by-step explanation:

We are basically trying to find the hypotenuse of the triangle.

The distance between the x is 2, and the distance between the y is 5, which makes a length and a width.

Pythagrenum theorem: a^2+b^2=c^2

2^2 is 4, 5^2 is 25.

4+25 is 29.

73 divided by the difference between 12 and 7


Answers

Answer:

14.6

Step-by-step explanation:

difference: 12-7=5

division: 73/5=14.6

The 73 divided by the difference between 12 and 7 is equal to 14.6.

To properly calculate 73 divided by the difference between 12 and 7, we follow these steps:

Calculate the difference between 12 and 7:

12 - 7 = 5

Divide 73 by the difference obtained:

73 ÷ 5 = 14.6

Therefore, 73 divided by the difference between 12 and 7 is equal to 14.6. This means that if we take the value 73 and divide it by the difference between 12 and 7, the quotient will be 14.6. The difference between 12 and 7 is 5, and when we divide 73 by 5, we obtain 14.6. It is important to note that the result is a decimal value, specifically 14.6.

Round off 54.3223 to 1 decimal place

Answers

Answer:

54.3

Step-by-step explanation:

since it is mentioned 54.3223, then u should see the two decimal places as they are asking to round it off to one decimal place. so we should see 54.32 only

if the second decimal is less than 5, then you should write the first decimal as it is like the above mentioned question (remember we are only supposed to mention one decimal place)

but if it is 5 or more, then you should move the first decimal to the next number. for example, 54.678. for this you should write 54.7 because the second decimal is more than 5

if they are asking to round it off to 3 places then you should see 4 decimal places

As a estimation we are told £3 is €4. Convert £25.50 to euros €

Answers

Answer:

£34

Step-by-step explanation:

→ Find how euros is in a pound

£3 = €4

£1 = €1.33

→ Multiply the euro by 25.50

1.33333 × 25.50 = £34

Answer:

€34

Step-by-step explanation:

First you'll want to find out how much £1 is.

Since we know £3 is equal to €4 we can:

divide £3 by 3 = £1divide €4 by 3 = €1.33

So, £1 = €1.33

With this in mind, we can find out what £25.50 is:

£1 x 25.50 = £25.50€1.33 x 25.50 = €34

Therefore, £25.50 = €34

Energy and mass are related by the formula

m is the mass of the object
c is the speed of light
Solve the equation for the mass of the object, m.

Answers

Answer:

m=E/c².

Step-by-step explanation:

Transposing the formula

E=mc²

we divide both sides by c² then cancel out where necessary so m would stand alone

E/c²=mc²/c²

cancelling c² on the right hand side, equation becomes

m= E/c²

The binomial letters from the table represent like terms are 'B' and 'C'.

What are binomials?

A mathematical expression made up of two terms joined together with a plus or minus sign.

Step 1: Multiplication of binomials:

It is necessary to multiply each phrase of the first binomial by each term of the second binomial when multiplying two binomials. Then, like terms are put together.

Step 2: Calculation for the given binomials:

A = (-2x)×(4x) = -8x²

B = (4x)×3 = 12x

C = 1×(-2x) = -2x

D = 1×3 = 3

As, it is shown from the given expressions that the values for B and C are alike.

Thus, B and C are the letters from the table represent like terms.
