average speed= total distance/total time taken

60+45= 105miles

1 mile= 1.609

105×1.609= 168.945km

168.945/4

Hence answer = 33.79 km/hr

Answer:

To find Alex's average speed for the whole journey, we can use the formula:

Average Speed = Total Distance / Total Time

Let's calculate the total distance traveled first:

Distance1 = 60 miles/hour * 3 hours = 180 miles

Distance2 = 45 miles/hour * 2 hours = 90 miles

Total Distance = Distance1 + Distance2 = 180 miles + 90 miles = 270 miles

Next, let's calculate the total time taken for the whole journey:

Total Time = 3 hours + 2 hours = 5 hours

Now, we can find the average speed:

Average Speed = 270 miles / 5 hours = 54 miles per hour

So, Alex's average speed for the whole journey is 54 miles per hour.

6

Step-by-step explanation:

There are 6 faces on a die so on average, one has to roll a fair die 6 times in order to get number 6 to show.

On average it's 6 as 6 sides a die has

But

i.e

There is 1/6 chances getting any number

Answer:

Explicit rule, because you can find the 40th term directly using the explicit rule. You would need to find the first 39 terms before finding the 40th terms using recursive rule.

Penta Trinomial

Step-by-step explanation:

Highest power is 5 (penta)

Highest number of term is 3 (tri)

Answer:

Step-by-step explanation:

Given polynomial

It has 3 terms so is trinomial

It has degrees as

As the greatest degree is 6, this expression is 6th degree trinomial

what values of a are the following expressions true?

|a-5| =5-a

Try putting values of ( a )

picking random number :-

Putting a = 6 :-

[tex] |a-5| =5-a \\ |6-5| =5-6 \\ | 1| = -1 \\ 1 \cancel = ( - 1) [/tex]

so a is not equal to 6

Putting a = 8

[tex]|a-5| =5-a \\ |8 - 5| =5-8 \\ |3| = - 3 \\ 3 \cancel = - 3[/tex]

a is also not equal to 8

so above values we can find a common result that a not equal to value bigger than 5

picking random number

Putting a equal to 1

[tex]|a-5| =5-a \\|1-5| =5-1 \\ | - 4| =4 \\ 4 = 4[/tex]

a can be equal to 1

Putting a equal to -3

[tex]|a-5| =5-a \\| - 3-5| =5-( - 3) \\ | - 8| = 8\\ 8 = 8[/tex]

a can be equal to -3

So we can have a common result that a can be equal to values less than 5

putting a equal to 5

[tex]|a-5| =5-a \\ |5 - 5| =5-5 \\ |0| =0 \\ 0 = 0[/tex]

So we can say a can be equal to 5

Answer:

$4.79

Step-by-step explanation:

divide $6.88/2

add $1.35 that's it

Money reduction on a paint set during a sale = $1.35

Cost of two paint sets Jenny bought in a sale = $6.88

Given :-

Cost of every paint set is equivalent .

Then :-

Cost of each paint set during the sale :-

[tex] = \frac{6.88}{2} [/tex]

[tex] = $3.44[/tex]

The cost of each painting set during the sale was $3.44 .

Cost of each paint set before the sale :-

[tex] = 3.44 + 1.35[/tex]

[tex] =$4.79[/tex]

Therefore , the cost of each paint set before the sale was = $4.79 .

Answer:

r = 3

Step-by-step explanation:

[tex]\dfrac{r}{2} - 3 = 3(4 - \dfrac{3r}{2} )[/tex]

The first step to solve for "r" is to simplify the distributive property on the RHS. To simplify the distributive property, we need to multiply the term outside the parenthesis with the terms inside the parenthesis.

[tex]\rightarrow \dfrac{r}{2} - 3 = 12 - \dfrac{9r}{2}[/tex]

Now, add 9r/2 and 3 both sides to isolate the constants and variables.

[tex]\rightarrow \dfrac{r}{2} + \dfrac{9r}{2} = 12 + 3[/tex]

Simplify both sides.

[tex]\rightarrow \dfrac{10r}{2}= 12 + 3[/tex]

[tex]\rightarrow 5r = 15[/tex]

Divide 5 both sides.

[tex]\rightarrow \boxed{r = \frac{15}{5} = 3}[/tex]

Answer:

  9) AB, AC, BC   or   c, b, a

  10) EG, (EF, FG)   or   f, (e, g)

Step-by-step explanation:

Sides are in the same order as their opposite angles. Generally the angle has an upper-case letter for its name, and the opposite side has the same lower-case letter for its name.

__

9) angle C is 32°, opposite side c, which is also labeled AB

  angle B is 68°, opposite side b, which is also labeled AC

  angle A is 80°, opposite side a, which is also labeled BC

Shortest to longest, the sides are c, b, a.

__

10) angle F is 50°, opposite side f, which is also labeled EG

The remaining two angles are both 65°, so have no smallest/largest order. Likewise their opposite sides are the same length, so have no shortest/longest order.

  angles E and G are opposite sides e and g, also labeled FG and EF, which are the same length

The shortest side is f; sides e and g are longer and are the same length.

Step-by-step explanation:

let width= 3x and length = 5x

perimeter = 64cm

now perimeter = 2(length+width)

64= 2(3x+5x)

64 = 16x

x = 4

therefore width= 3 X 4 = 12

length = 5 X 4 = 20

Answer:

Reshmi bought more cloth by 4/15...

Step-by-step explanation:

1st equalize the denominator of 2/3 and 2/5

lcm of the denominators 3 and 5 is 15

2/3*5/5=10/15

2/5*3/3=6/15

Rashmi bought 10/15 m cloth

madhu bought 6/15 m cloth .

therefore, Rashmi bought more cloth

by how much more?

10/15-6/15 = 10-6/15=4/15

therefore, reshmi bought more cloth by 4/15
