laila [671]3 years ago

Answer:

15

Step-by-step explanation:

To solve this we need to multiply from left to right:

another way to write 40 is 40/1

so multiply 3/8 and 40/1

(You need to multiply the top with the top and bottom with bottom)

3 times 40 is 120 8 times 1 is 8 so the answer will look like this:

120/8

But we can simplify it:

120 divided by 8 is 15

(If you don't know how to divide long division divide with smaller numbers like 2, 3, 5, 7, and so on)

Alternate way:

Divide by a prime number that can be divided in this case it is 2, stop when that number cannot be divided by that prime number

120: 120/2= 60    60/2= 30     30/2= 15

8: 8/2= 4    4/2= 2     2/2= 1

Hope this helps!

What is x?? I'm so confused!
LiRa [457]

Answer:

x = 468%

Step-by-step explanation:

I see a proportion here.

we want to solve for the variable x in the proportion:

18% / (2 weeks) =   ( x %) / (52 weeks)

here we should multiply 52 to boths sides

(52 weeks) * 18%  / (2 weeks) =   x %

26  * 18% =  x %

x = 468 %

ONE HUNDRED POINT AND BRAINIEST FOR BEST CORRCET ANSWER! PLS HELP ASAP! Cami is comparing the growth rates in the value of two i
Xelga [282]

Answer:

A(t) = 1.032^t

Ring rate grows faster

Annual rate of ring: 4.03%

Step-by-step explanation:

A(t) = (1 + 3.2%)^t

A(t) = (1.032)^t

Ring:

(1 + 0.33%)^(12t)

(1 + 0.0033)^(12t)

(1.0033¹²)^t

1.040326705^t

Increase of (1.040326705 - 1) × 100

= 4.0326705%

Faster rate: ring

An atomic nucleus has a charge of +40e. What is the magnitude of the electric field at a distance of 1.0 m from the center of th
ASHA 777 [7]

Answer:

E=5.76\times 10^{-8}N/C

Step-by-step explanation:

We are given that

Charge of atomic nucleus,q=+40 e=40\times 1.6\times 10^{-19}C

Because

1 e=1.6\times 10^{-19} C

Charge of atomic nucleus=64\times 10^{-19}C

Distance of charge form the center of nucleus=r=1 m

We have to find the magnitude of  electric field at distance r

E=\frac{Kq}{r^2}

Where K=9\times 10^9Nm^2/C^2

Using the formula

E=\frac{9\times 10^9\times 64\times 10^{-19}}{1}=576\times 10^{-10}N/C

E=\frac{576}{100}\times 10^2\times 10^{-10}=5.76\times 10^{2-10}=5.76\times 10^{-8}N/C

Using identitya^x\cdot a^y=a^{x+y}

Hence, the magnitude of electric field=E=5.76\times 10^{-8}N/C
