Answer:

It takes 534.54 watts

Step-by-step explanation:

Given :

Mass of the book = 30kg

Distance = 10m

Time = 5.5 sec

To Find:

How much power did it take = ?

Solution:

Step 1: calculate the work done

Work done = $m\times a \times d$

where

m = mass

a = acceleration due to gravity

d = distance

Substituting the values,

Work done = $30\times 9.8 \times 10$

=> 2940 Nm

Step 2: calculate the Power

We know that

$Power = \frac{\text{ work done}}{time}$

Substituting the values,

$Power = \frac{2940}{5.5}$

Power = 534.54 watts

Heidi and Andrew designed two raised flowerbeds for their garden. Heidi's flowerbed was 5 feet long by 3 feet wide, and Andrew's

d1i1m1o1n [39]

Answer:

$V=90\ ft^3$

Step-by-step explanation:

-Given the two heights are similar:

#Heidi's flowered bed dimensions and volume is calculated as:

$v=lwh$

$=5\times 3\times 2\\\\=30\ ft^3$

#The width of Andrew's is twice Heidi's. The width and volume is thus calculated as:

$w_a=2\times 3=6 \ ft\\\\V_a=lwh\\\\=5\times 6 \times 2\\\\=60\ ft^3$

#Total soil volume of the soil used is determined by summing the two different flowerbed volumes:

$V=V_h+V_a\\\\=30+60\\\\=90 \ ft^3$

What is the perimeter of triangle DEF

LuckyWell [14K]

Remember that A squared plus B squared equals C squared.

Since sides F_D and D_E are both 3, the answer cannot be 4.2 or 2.4.

SO basically you just add 3 + 3 = (The side F_E, which you can get by putting numbers in the formula), you should get your answer.

3² + 3² = Line EF²
9 + 9 = Line EF²
18 = Line EF²
√18

You get the idea. Hope this helps!

A cone that is sliced through the vertex would make the shape of a triangle.

You are told the h eight is 10 cm and the radius is 4 cm.

The radius would be half the base, so the base would be 4 * 2 =8 cm.

The area of the triangle is found by multiplying the base by the height, then dividing by two.

Area = 8 x 10 = 80

80 / 2 = 40 square centimeters.
