Answer:
a.) 5(3t+2)+ 7(2t+5)
b.) 15t+10+14th+35
c.) $132
Step-by-step explanation:
a.) 5(3t+2)+ 7(2t+5)
b.) 15t+10+14th+35
Simplify to :
29t+45
c.) Substitute
29(3) +45
87+45=132
$132
The answer is 72 (--> second choice).
I can prove it without calculator so you believe me:
![6\sqrt{8}\cdot3\sqrt{2}=6\cdot3\cdot\sqrt{8}\sqrt{2}=6\cdot3\cdo\sqrt{8\cdot2}=\\= 6\cdot3\cdot\sqrt{16}=6\cdot 3\cdot 4 = 72](https://tex.z-dn.net/?f=6%5Csqrt%7B8%7D%5Ccdot3%5Csqrt%7B2%7D%3D6%5Ccdot3%5Ccdot%5Csqrt%7B8%7D%5Csqrt%7B2%7D%3D6%5Ccdot3%5Ccdo%5Csqrt%7B8%5Ccdot2%7D%3D%5C%5C%3D%206%5Ccdot3%5Ccdot%5Csqrt%7B16%7D%3D6%5Ccdot%203%5Ccdot%204%20%3D%2072)
Answer:
528 square inches
Step-by-step explanation:
SA = 2(10·16) + 2(10·4) +2(4·16)
= 2(160)+2(40)+2(64)
= 320 + 80 + 128
= 528 square inches
Answer: 700 miles.
Step-by-step explanation:
1. You know that 23% of the total distance of the flight from Albuquerque New Mexico to Austin Texas is 161 miles.
2. Then, keeping that information on mind, you can calculate the total distance of the flight (which you call
) as following:
![\frac{161miles}{23\%}=\frac{x}{100\%}](https://tex.z-dn.net/?f=%5Cfrac%7B161miles%7D%7B23%5C%25%7D%3D%5Cfrac%7Bx%7D%7B100%5C%25%7D)
Solve for
. Then, you obtain that the result is:
![x=\frac{161miles*100\%}{23\%}\\x=700miles](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B161miles%2A100%5C%25%7D%7B23%5C%25%7D%5C%5Cx%3D700miles)
