In this question, you know that the machine packs
of a box every
of a minute. Since it is constant, you simply have to double the half a minute to a full minute and then also double the rate to get
boxes packed per minute. And
is equal to
the inside of quadrilateral is always 360°.So add 75°,90° and 75° and then subyaract from360°.
x+75°+75°+90°=360
×+240°=360°
x=360°-240°
x=120°
2659 Dollars its pretty simple all you have to do is 2931-362 and then you get 2659
Answer:
39
Step-by-step explanation:
1. Subtract the numbers ... 3(3×3+4)
2. Multiply the numbers ... 3(9+4)
3. Add the numbers ... 3×13
4. Multiply the numbers ... 39
The ladder, the wall and the floor form together a triangle rectangle, where the ladder is the hypotenuse of the triangle and the floor and wall are the cathetus. We know from Pythagoreas theorem that the square of the hypotenuse is equal to the sum of the two cathetus squared added, so we can write an equation with the data we have:
hyp^2 = cath1^2 + cath2^2
<span>hyp^2 = wall^2 + floor^2
</span>so we have the hypotenuse value, the floor value and the unknown is the wall height:
(22)^2 = wall^2 + (7)^2
484 = wall^2 + 49
wall^2 = 484 - 49 = 435
wall = √435
wall = 20.9
therefore the ladder touches the wall 20.9 feet above the ground
