What’s the area of the shape

Mathematics

Answer:

19.63

Step-by-step explanation:

To find the area of a circle you can use the formula πr². The diameter (10) is twice the radius. So, the radius is 5. 5² = 25. 25x π =25π. Then you must divide by 4 because the shape is 1/4 a circle.

Hope this helps ;)

What is the distance covered by a train while slowing down from

alukav5142 [94]

Answer:

The distance covered is 113.75 m

Step-by-step explanation:

As per the question:

The initial velocity of the train, v = 20 m/s

The final velocity of the train, v' = 6 m/s

Uniform deceleration, a = 1.6 $m/s^{2}$

Or uniform acceleration, a = - 1.6 $m/s^{2}$

<em>Here, the body decelerates, i.e., slows down at a uniform rate thus we take acceleration with negative sign.</em>

Now, to find the distance covered, s:

Using the eqn of Kinemetics:

$v'^{2} = v^{2} + 2as$

$6^{2} = 20^{2} + 2(- 1.6)s$

$36 - 400 = - 3.6s$

$s = \frac{- 364}{- 3.6} = 113.75\ m$

Daisy is building a rectangular pen for her chickens along one wall in her back yard. She needs to build a fence

frosja888 [35]

Answer:

Daisy has one side of the rectangular pen along the wall, so she needs one width, w, and two lengths, 2ℓ. She has at most 125 feet of fencing materials to build the fence for her pen

1 second/24 frames

so if he started with 0 frames

time s = (1/24) (additional f)

but he already had at least 250 frames

time s = (1/24)( f-250) or maybe less time if he had more than 250

24 s </= f - 250

f >/= 24 s + 250

Help clear the fractions I need more help

marishachu [46]

Answer:

x = $\frac{43}{6}$

Step-by-step explanation:

Given

$\frac{3}{4}$ x - 5 = $\frac{3}{8}$

Multiply through by 8 ( the LCM of 4 and 8 ) to clear the fractions

6x - 40 = 3 ( add 40 to both sides )

6x = 43 ( divide both sides by 6 )

x = $\frac{43}{6}$
