up to = less than or equal to
at least = greater than or equal to
The answer is correct
the max weight shall be 80
mass of small box = 5 lb. ( and there are x number of boxes )
Mass of big box = 12 lb. ( and there are y number of boxes )
adding them up shall be less than or equal to 80 ( as the shelf can withstand up to 80 lbs. )
And the minimum number of boxes shall be equal to 4
If we take the x as the number of boxes, then x would be greater than or equal to 4
Hope my answer helps!
Answer:
hight is 12
Step-by-step explanation:
Pythagoras theorem 3:4:5which is3×3=9and 3×4=12and 3×5=15
You would take 10.85 times .4% which gives you 4.34 then you would add 4.34 to 10.85 for a total of 15.19
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>Formulas used:</u>
- sin θ = sin (180 - θ)
- sin θ = opposite/hypotenuse
<u>Opposite:</u>
- y- coordinate of given point = 21
<u>Hypotenuse:</u>
- √x²+y² = √20²+21²= √841 = 29
<u>Then</u>
Correct choice is D
