20 / (3 * 17!)

20 * 19 * 18 * 17 / (6 * 17)

20 * 19 * 18 / 6

20 * 19 * 3

The question is Let h(x)=2x+5  and <span>g(x)=8-3x
what is the value of </span><span>h(g(1.5))
 the answer 

</span>h(g(1.5))= 2g(1.5)+5, and <span>g(1.5)=8-3(1.5)=3.5, so
</span>h(g(1.5))= 2<span>(3.5)+5= 12

John needs 13 bottles of water from the store. john can only carry 3 at a time. what's the minimum number of trips john needs to
Lostsunrise [7]
The minimum amount of trips would be 5. This is because in one trip he can only carry 3, so you would take 5 times 3. You may think it should be 4 trips, but 12 is 1 short of 13,so you would have to make one extra trip to get all 13 bottles.

Step-by-step explanation:

The chip is 14  nanometers

14 * .000000001

.000000014

Move the decimal 8 places to the right, because we need 1 number in front of the decimal for scientific notation.  The exponent will be -8 because  we moved it 8 places to the right

A metal frame is constructed in the form of an isosceles trapezoid. Each base angle measures 80°, the length of the base is 7 fe
jonny [76]
Height of a trapezoid:
h = 5 · sin 80° = 5 · 0.985 = 4.924
x = 5 · cos 80° = 5 · 0.17365 = 0.868
7 - x = 7 - 0.868 = 6.132
By the Pythagorean theorem:
d² = 6.132² + 4.924²
d² = 37.6 + 24.25
d² = 61.85
d = √61.85
d = 7.86 ≈ 8
Answer: The length of a diagonal brace is 8 feet.
