1/8 + 1/4 estimate the sum or difference

stepladder [879]

When estimating you need to round up or down to find something close to the real answer. Here we would round 1/8 down to 0 and 1/4 down to 0. So 0+0=0.

Your estimated answer is 0

The real answer is 3/8 so 0 is close and that is the point in estimating

The sum of Ellie’s ages an Genya’s age is 60. In 6 years, genus will be 8 times as old as Ellie. How old is Ellie now?

Aleonysh [2.5K]

Ellie's age = 58 years

Genya's age = 2 years

Step-by-step explanation:

Let e represent Ellie's age

and

g be Genya's Age

Then

$e+g = 60\ \ \ Eqn1$

In six years

Ellie will be e+6 years old and Genya will be g+6 years old

then

$g+6 = 8(e+6)\\g+6 = 8e+48\\g = 8e+48-6\\g = 8e+42\ \ \ Eqn2$

Putting g= 8e+42 in equation 1

$e+8e+42 = 60\\9e +42 -42 = 60-42\\9e = 18$

Dividing both sides by 9

$\frac{9e}{9} = \frac{18}{9}\\e=2$

Putting e = 2 in equation 1

$e+g = 60\\2+g = 60\\g = 60-2\\g = 58$

Hence,

Ellie's age = 58 years

Genya's age = 2 years

Any help to solve this problem. Provide steps. Thnx

Answer:

284cm^2

Step-by-step explanation:

first, we split up the shape into seperate sections that we can easily find the areas of.

i will draw vertical lines in the bottom left and right, leaving me with 2 seperate rectangles and 1 irregular pentagon.

we know that these rectangles are 4x8cm, so we do 4 * 8 which gives us 32.

there are 2 of these, so 32 x 2 = 64cm^2.

now, i chose to seperarte the pentagon into a rectangle and a triangle,

and i found the height and width of the rectangle to be (18 - (4+4)) x (8+7), or 10 x 15.

the area of the rectangle is 150cm^2.

now, for the triangle.

the line through the centre of th shape is 22cm long, but we only want the part in the triangle. luckily, there are mesurements that can help us with this.

8 + 7 = 15.

22 - 15 = 7.

now we know that the height of the triangle is 7 cm.

from earlier, we also know the base, which is 10cm.

7 x 10 = 70cm^2.

now we add all these together:

70 + 150 + 64 = 284cm^2
