Answer:
Number of rotations r < 5.25
Step-by-step explanation:
Given: bottom of the desktop is 74.5 cm from the floor.
Top of Ignacio's legs are 49.3 cm from the floor.
Each clockwise rotation on the knob raises Ignacio's legs by 4.8 cm.
To find: Inequality to determine the number of clockwise rotations r, Ignacio could make with the knob without his legs touching the desk.
Solution: Distance between Ignacio's legs and the base of the desktop = 74.5 -49.3 = 25.2
Therefore inequality will be
Height raised in one rotation × r < 25.2
4.8×r < 25.2
r < 25.2÷4.8
r < 5.25
59*3 = 177 (Hope this helps!)
Hey there!
First, we will multiply -100 by a.
-100 x a = -100a
Now we have:
-100a x 56
Let’s multiple this as well.
-100a x 56 = -5600a
Your answer is -5600a.
Hope this helps!
Answer:
18.8 minuites
Step-by-step explanation:
20% of 5 is 1 so the second time is 6 and 30% of 6 is 1.8 so it will be
5+6+7.8=18.8
Answer:
60 °
Step-by-step explanation:
Applying the law of sine we have the following:
160 / Sin B = 80 / Sin 30 °
We solve for B and we have:
160 / Sin B = 80 / 0.5
160 / Sin B = 160
Without B = 160/160
B = Arc Sin (1)
B = 90 °
Now to calculate the other angle (true
course) would be:
A = 180 ° - (B + C)
A = 180 ° - (90 ° + 30 °)
A = 60 °
That is to say that true course is 60 °
