Answer:

334 in^2.

Step-by-step explanation:

The surface area = area of the top prism + area of the bottom - 2 * area of the base of the  top smaller prism

= 2(5*3 + 5*3 + 3*3) + 2(9*7 + 9*5 + 7*5) -  2* 3*5

= 2* 39 + 2*143 - 30

= 334

Can someone help me Please
alisha [4.7K]
Jane:  Think:  the hypotenuse of her ramp is 14 inches and the angle opposite the rise is 30 degrees.  Thus, cos 30 deg = (adj side) / (hyp) = (adj side) / (14 in).

Solving for (adj side), we get   (adj side) = (14 in)(sqrt(3)/2) = 7 sqrt(3) inches.

Can someone pls help? ab to fail geometry. any help is nice.
Mamont248 [21]
By the law of cosines, the angle C satisfies

8.77^2=2^2+9^2-2\times2\times9\times\cos C

which reduces to

\cos C=0.2246\implies C=\arccos(0.2246)\approx1.34422\text{ rad}

which converts to approximately 77 degrees (this can be done my multiplying by 180 and dividing by pi).

It’s a right angle! which equals to 90° you already have 20° and 8° so you add them together and you get 28. now you have to subtract 90-28 which equals to 62.

ANSWER: 62°

Suppose you work for a large coffee distribution that has a secret coffee blend it sells to local stores. Gazebo blend with Kona
KATRIN_1 [288]

Answer:

12 Pounds

Step-by-step explanation:

The proportion of the secret blend is 90/27. When there is only 40 pounds of gazebo, your proportion looks like this:  40/X. X being pounds of Kona. When you are to simplify 90/27 you're left with 10/3. Cross multiply 10/3 and 40/X to and simply to get 10x = 120, leaving you with 12 as your final answer. Hope this explanation helps.
