Answer:

7.38 minutes

Step-by-step explanation:

Given

Distance= 8km

speed = 65km/h

Time=?

From physics,

Speed= distance/ time

Then substitute the values to find time

65= 8/ time

Time= 8/65

=0.1231 hrs

To Convert to minutes

1hr= 60 mins

0.1231 hrs = X minutes

Cross multiply, we have

X minutes=( 0.1231 × 60)/1

= 7.38 minutes

Hence, it takes 7.38 minutes for him to cover this distance

mafiozo [28]

Answer:

A. 4

Step-by-step explanation:

Constant of proportionality (k) = y/x

We can use the coordinates of any point on the line to find k.

Let's use (2, 8)

Constant of proportionality (k) = 8/2

Constant of proportionality (k) = 4

:( <br> A=?<br> B=?<br> please help me
Helen [10]

a= 16x+16

b= 40x + 15

Step-by-step explanation:

We know that perimeter of a rectangle is

2(l + b)

So therefore

2(8x + 3 + 5) = a

=  > 16x+ 6 + 10 = a

=  > 16x + 16 = a

Answer= A) that is perimeter is 16x+16

We know that area of a rectangle is l×b

So therefore

(8x + 3) \times 5

= 40x + 15

Answer = b) that is area is 40x + 15

Find the 14th term in the sequence 1, 1/3, 1/9, … Find the sum of the first 10 terms of the sequence above.
pychu [463]

Answer:

This is a geometric progresion that begins with 1 and each term is 1/3 the preceeding term

   Let Pn represent the nth term in the sequence

 

   Then Pn = (1/3)^n-1

 

   From this P14 = (1/3)^13 = 1/1594323

 

5. The sum of the first n terms of a GP beginning a with ratio r is given by

   Sn = a* (r^n+1 - 1)/(r - 1)

 

   With n = 10, a = 1 and r = 1/3, S10 = ((1/3)^11 - 1)/(1/3 - 1) = 1.500
