Which expression shows another way to write 36+16?<br> 4(9)+4<br> 4(9+4)<br> 6(6+8)<br> (6+4)(6+4)

allsm [11]

Answer:

36+16= 52

4(9)+4= 40, which does not equal 52.

4(9+4) = 52.

6(6+8) = 84, which does not equal 52.

(6+4)(6+4) = 100, which does not equal 52.

So, 4(9+4) is correct.

Let me know if this helps!

the variable, n represents a number that spectator chooses. what is the result after the calculation of 2n + - n - 4?

Aleks04 [339]

I could be wrong here, but I think n is 4? I plugged it in, but I was a bit unsure of what you were asking. Wish you the best!

Tammy buys a 4-gigabyte memory card for her camera. Dijonea buys a memory card with twice as much storage as Tammy’s. One gigaby

tigry1 [53]

Answer:

Dijonea have 8192 megabytes on her memory card

Step-by-step explanation:

Capacity of Tammy's memory card = 4-gigabyte

given that Dijonea buys a memory card with twice as much storage as Tammy’s

Thus,

Capacity of Dijonea's memory card = 2*Capacity of Tammy's memory card

Capacity of Dijonea's memory card = 2*4-gigabyte = 8-gigabyte

Given that

1 gigabyte = 1,024 megabytes

we have to find value of 8 gigabyte in terms of megabytes

for that we multiple both side in above equation by 8

1 *8 gigabyte = 1,024 *8 megabytes

8 gigabyte = 8192 megabytes

Thus, Dijonea have 8192 megabytes on her memory card

A 12 vdc power supply powers a blue high intensity led with a forward voltage of 4.5 volts. The led is rated to withstand a maxi

dimulka [17.4K]

Answer:

Resister of 0.15 W is to be added.

Step-by-step explanation:

In a given circuit we have the attachments

A power supply of 12 V

High intensity LED with forward voltage = 4.5V

LED is rated to withstand a maximum current of 20 mA or $20.10^{-30} A$

We have to calculate the size of a resister to be connected in series.

Here we will apply the Ohm's law for the calculations

Total voltage of the circuit = voltage of LED + voltage across resistance.

$12=4.5+20.10^{-3}.r$

r = (12 - 4.5)/20.10^{-3}

r = 7.5×10^{3}/20 = 375 ohm

Therefore power of the resistance = i².r

$P=i^{2}\times r$

$=(20\times 10^{-3})^{2}\times 375$

= 0.15 W

Therefore a resister of 0.15 W is to be added.
