A car bus travels at a speed of 45 km/h. How far will it travel in 36 minutes?

tensa zangetsu [6.8K]

Correct Question:

A car/bus travels at a speed of 45 km/h. How far will it travel in 36 minutes?

(Note- Corrected part is written in bold.)

Solution:

$\sf Speed = 45 \: km/h$

$\sf Time=36 \: mins$

$\sf = \frac{36}{60} \: hour \: (Since \: we \: know,1 \: hour \: = 30 \: mins$

$\sf = \frac{3}{5} \: hour$

$\sf \: Distance = Speed \times Time$

$\sf = \: 45 \times \frac{3}{5} \: km$

$\sf = \frac{45 \times 3}{5} \: km$

$\sf \: Distance=27 \: km$

Hence, a car/bus travels 27 km in 36 mins.

Graph Ex+ 3y = 24 a. b. c. d.

8090 [49]

Answer:

(b)

Step-by-step explanation:

Given

$8x + 3y = 24$

Required

The graph

First, make y the subject

$3y = 24 - 8x$

Divide through by 3

$y = 8 - \frac{8}{3}x$

Let x = 3

$y = 8 - \frac{8}{3}*3 = 8 - 8 = 0$

Let x = 6

$y = 8 - \frac{8}{3}*6 = 8 - 16 = -8$

So, we plot the graph through

$(3,0)$ and $(6,-8)$

I need you show me your answer for number 51

iragen [17]

It's graph C. because on the first pair of numbers you can see that they both line up with the graph. Also, if you find the pattern between the numbers (x-3 and y-1) the graph C. lines up.

Hoped I helped! :)

One side of a square has endpoints (4.7) and (-3,5). What is the perimeter of the square?

Goryan [66]

Answer:

= 4√53 units

that is option(a)

Step-by-step explanation:

all sides of the square are of the same length

so if we get the length if this side, we can calculate its perimeter

there's this formula,

side length between two points, let's say A(x, y) and B(p, q), is equal to 

$\mathsf{ \sqrt{ {(x - p)}^{2} + {(y - q)}^{2} } }$

so here we go,

the same points A and B here are

(4, 7) and (-3, 5)

therefore, side length :-

$= \mathsf{ \sqrt{( {7 - 5})^{2} + {(4 - ( - 3))}^{2} } }$

$= \mathsf{ \sqrt{ {2}^{2} + {7}^{2} } }$

$= \mathsf{ \sqrt{4 + 49} }$

$= \mathsf{\sqrt{53} }$

the side length comes out to be √(53) 

now perimeter of a square is

4 × side length

= 4√53 units
