1/2+ 1/4
= 2/4+ 1/4
= 3/4

1/12+ 1/6
= 1/12+ 2/12
= 3/12
= 1/4

Therefore, 1/4+ 1/6+ 1/12
= (1/12+ 1/6)+ (1/12+ 1/6)
= 2*(1/12+ 1/6)
= 2* (1/4)
= 2/4
= 1/2

Hope this helps~

In order to add fractions, they need common denominators
1/2 * 2 = 2/4 + 1/4 = 3/4
1/6 * 2 = 2/12 + 1/12 =3/12, divide by 3 to reduce = 1/4
1/4 * 3, 1/6 * 2 = 3/12 + 2/12 + 1/12 = 6/12, divide by 6 to reduce = 1/2

Step-by-step explanation:

Did you mean:

= (a - b)(a + b)

= a.a + b.a - b.a - b.b

= a² + ba - ba - b²

= a² - b²

Todd wants to find 352 + 116. Break

jekas [21]

Answer

given,

352 + 116

we have to break 116 and use it on open number line

breaking of number 116

116 = 100 + 10 + 6

And addition will be shown in the number line attached below

now,

352 + 100 = 452

452 + 10 = 462

462 + 6 = 468

we know

sum of

352 + 116 = 468

A set of bookshelves rests on a hard floor surface on four legs, each having a cross-sectional dimension of 3.0×4.1cm in contact

tatiyna

Answer:

$5.22\cdot 10^5 Pa$

Step-by-step explanation:

The pressure exerted by an object is given by:

$p=\frac{F}{A}$

where

F is the magnitude of the force

A is the area of the surface perpendicular to the force

In this problem, the force is the weight of the books + the shelf, which is given by

$F=mg$

where

m = 262 kg is the total mass

$g=9.8 m/s^2$ is the acceleration of gravity

Substituting,

$F=(262)(9.8)=2568 N$

The area of the four legs is:

$A=4(3.0 cm\cdot 4.1 cm)=4(12.3 cm^2)=49.2 cm^2 = 49.2\cdot 10^{-4} m^2$

Therefore, the pressure exerted on them is:

$p=\frac{F}{A}=\frac{2568}{49.2\cdot 10^{-4}}=5.22\cdot 10^5 Pa$

A country's population in 1995 was 32 million. In 1997 it was 34 million. Estimate the population in 2003 using the exponential

fomenos

Hello! Looking at the numbers, you can see that the population of a country goes up by 1 million people each year. You could also say that it goes up by 2 million every 2 years. At this rate, the population in 2003 was 40 million. This is because 1997-2003 are 6 years apart. Do 1 million * 6 to get 6 million and add that to 34 million from 1997 to get 40 million in 2003.

Prior to hosting an international soccer match, the local soccer club needs to replace the artificial turf on their field with g

r-ruslan [8.4K]

Answer:

$44,313.75

Step-by-step explanation:

First, we need to turn the km into meters. There are 1000 meters in a km meaning we need to multiply each of these values by 1000.

0.101 km * 1000= 101 meters

0.065 km * 1000 = 65 meters

Now we need to multiply these values together to find the area of the field

101m * 65m = 6,565 $m^{2}$

Finally, we need to multiply this area by the cost per square meter

6,565 $m^{2}$ / 6.75 = $44,313.75

The total repair will cost $44,313.75
