Step-by-step explanation:

The formula of a surface area of a sphere:

$SA=4\pi R^2$

<em>R</em><em> - radius</em>

<em />

We have <em>R = 30m</em>.

Substitute:

$SA=4\pi(30^2)=4\pi(900)=3600\pi\ m^2$

My lawn is 17ft wide and 20ft long, each square foot of lawn gets 1350 new snowflakes per min how much snow in kilograms accumul

Alina [70]

Answer:

46.818 kg

Step-by-step explanation:

First, find the surface area of your yard. This is found by multiplying the length and width.

The equation for this is (l*w)=sa

So,

l=20ft

w=17ft

(20*17)= 340 square feet.

So, if each square foot gets 1350 new flakes per minute, you are going to find how much the entire yard gets in a minute by multiplying the surface area by 1350.

So,

(340*1350)= 459000 flakes for the entire yard in one minute.

Since there is 60 minutes in an hour, multiply 459,000 by 60.

459,000*60= 27,540,000 new flakes in the yard per hour.

Now, to find the weight in milligrams:

27,540,000*1.7= 46,818,000 mgs

Finally, because a kilogram is equal to one million milligrams (mg),

46,818,000/1,000,000= 46.818 kg

Answer:

Step-by-step explanation:

We can make this and equation

x • y = 1260

x = 3y +48

Our equation is

(3y +48)y = 1260

We get y = 14

Write and solve a problem involving money that can be solved with a multiplication equation. tell what the variable represents

olganol [36]

Ben wanted to take some money from his Friends to build his family a home. He said that he would give the money back after 12 months. So he would give 1500$ a month. How much money did he borrow?
1500*12=x

Matilda got also money, she told Ben, I got x $ from my dad and y $ from mom. all they gave me was 5000$. If I gave mom Half of the moneys I got from her than I would have 3000$ left to pay. How much did she borrow from her parents?
x+y=5000
and
x+y/2=3000

so x=5000-y
and
5000-y+y/2=3000

so
x=5000-y
and
y=4000

so x=1000 and y=4000
