Answer:

-101 feet

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the relevant relation is ...

Tan = Opposite/Adjacent

Opposite = Adjacent × Tan

height = (0.5 × 5280 ft) × tan(47°) ≈ 2831 ft

The usual relation between estimates and errors is ...

error = estimate - actual

Then ...

actual = estimate - error

For the given angle and error, the actual angle is ...

actual angle = 47° -(-1°) = 48°

actual height = (2640 ft)·tan(48°) ≈ 2932 ft

Then the change in the height of the mountain due to the error is ...

2831 ft -2932 ft = -101 ft

The error of -1° in angle estimate creates an error of -101 ft in the height estimate.

The first day of Sam's vacation was a Monday. What day of the week was the Day 36 of Sam's vacation?

makvit [3.9K]

Answer:

A. Monday

Step-by-step explanation:

The solution to this problem can be found by creating a table

If Day 1 was Monday, then

Mon Tues Wed Thur Fri Sat Sun

1 2 3 4 5 6 7

8 9 10 11 12 13 14

...............

We can see that the multiples of 7 are falling on Sundays so we will divide 36 by 7 to get the closest multiple of 7 to 36.

The closest multiple of 7 near 36 is 35 so Day 35th will fall on Sunday and Day 36 will be on Monday

Hence, Option A is the correct answer..

If a is an odd integer and b is an even integer, which of the following makes an odd integer?

Serga [27]

9514 1404 393

Answer:

D.) a+2b

Step-by-step explanation:

The integers 'a' and 'b' can be any, so you can choose a couple and evaluate these expressions to see what you get. For example, we can let a=1 and b=0. For these values, the offered expressions evaluate to ...

A) 3(0) = 0 . . . even

B) 1 +3 = 4 . . . even

C) 2(1+0) = 2 . . . even

D) 1 +2(0) = 1 . . . odd

_____

Additional comment

These rules apply to even/odd:

odd × odd = odd
odd × even = even
even × even = even
odd + odd = even
odd + even = odd
even + even = even

Then A is (odd)(even) = even; B is (odd)+(odd) = even; C is (even)(whatever) = even; D = (odd)+(even) = odd.

An ice cream shop sells 6 different flavors, 4 toppings, and 3 types of cones. How many different combinations of two different

Bas_tet [7]

Answer:

360 combinations

Step-by-step explanation:

To calculate the number of different combinations of 2 different flavors, 1 topping, and 1 cone, we are going to use the rule of multiplication as:

6 * 5 * 4 * 3 = 360

1st flavor 2nd flavor topping cone

Because first, we have 6 possible options for the flavor, then we only have 5 possible options for the 2nd flavor. Then, we have 4 options for the topping and finally, we have 3 options for the cone.

It means that there are 360 different combinations of two different flavors, one topping, and one cone are possible
