Explain how solving 8+2 can help you solve 80+20.

2 answers:

8 0

First do 8 + 2 and then it's gen right so you do the same just that this time you add a 0 to a 10 like8+2=10 add a zero and get 100

Becuase 80 is the same as 8 but has an extra 0 at the end (which makes it 80) and same for 20 to 2. 8 + 2 = 10 (now add a zero at the end). The answer should be 100.

A line had a slope of 2/3 and a y intercept at (0,14).What is the x intercept of the line?

pychu [463]

Answer:

y=2/3x+14

Step-by-step explanation:

The standard form of an equation in slope-intercept form is y=mx+b where m=slope and b=y-intercept.

Given a y-intercept of 14 and a slope of 2/3, we can plug into the variables and get the equation y=2/3x+14

The x-intercept would be when y=0, so plugging in y=0 to the equation gets us:

0=2/3x+14

-14=2/3x

21=x

So the x-intercept is 21

Two cars leave a rest stop at the same time and proceed to travel down the highway in the same direction one travels at an avera

Alika [10]

The two cars will be 5.5 miles apart after 5.5 hours.

Step-by-step explanation:

Given,

Speed of first car = 57 mph

Time = 5.5 hours

Distance covered by first car = Speed * Time

Distance covered by first car = 57*5.5 = 313.5 miles

Speed of other car = 58 mph

Distance covered by other car = 58*5.5 = 319 miles

Difference = 319 - 313.5

Difference = 5.5 miles

The two cars will be 5.5 miles apart after 5.5 hours.

The length and breadth of rectangular field are 240m and 200m respectively. Find the cost of digging the field at Rs 10 per m^2

Inga [223]

Answer:

Please check the explanation.

Step-by-step explanation:

Given

The length of rectangular field = l = 240m

The breadth of rectangular field = w = 200m

We can determine the area of the rectangular field using the equation

$A=wl$

where

$l$ is the length

$w$ is the width

substituting l = 240m, and w = 200m in the formula

$A=wl$

A = 240 × 200

A = 48000 m²

Given that the cost of digging the field at Rs 10 per m².

Thus,

The cost of digging the field of the area 48000 m² = 10 × 48000

= 480000 Rs

Therefore, the total cost of digging = 480000 Rs
