Answer:

Step-by-step explanation:

7b−4a+6c2

a=2

b=6

c=5

7b-4a+6c2

7x6 - 4x2 + 6x5x2

42-8+60

using Bodmas, we add first

42+52=94

the answer is not in the options, kindly review if theres a mistake in the question

Answer:

Step-by-step explanation:

Statistically this is valid

But, in Alaska average daytime summer temperatures range from approximately 55 to 78 °F (12.8 to 25.6 °C); average daytime winter temperatures are about 5 to 30 °F (−15.0 to −1.1 °C). SO, they don't need cooling when compared to rest of the USA. Therefore this will not be valid.

2. The bottom of a ramp is placed 15 feet from the edge of a stage

Firdavs [7]

Answer:

The slope of the ramp is 1.

Step-by-step explanation:

See the diagram attached.

Here, AC = 15 ft. and ED = 5 ft. while AE = 10 ft.

Then, EC = (15 - 10) = 5 ft.

Now, considering the right triangle Δ EDC, if $\theta$ is the inclination of the ramp, then $\tan \theta = \frac{ED}{EC} = \frac{5}{5} = 1$
