The bottom of Ignacio's desktop is 74.5cm from the floor. Ignacios sits in his adjustable chair, and the tops of his legs are 49
Xelga [282]

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

Camp Ground A has an area of 300 square yards with a maximum capacity of 25 pup tents. Camp Ground B has an area of 480 square y
Damm [24]

Answer:

40 pup tents

Step-by-step explanation:

Since Ground A has area 300 and maximum capacity is 25 tents, so each tent would take up area of  300/25 = 12 sq yards.

Since Ground B's tents should occupy same area as Ground A's tents (12 sq. yards), the maximum capacity of this tent (480 sq yd) would be:

480/12 = 40 pup tents

This is the maximum capacity.

7²=49

7³=343

So this means the value of x lies between 2 and 3, so here answer 11.71 is unreasonable

b) In this case, to solve the equation, introduce logs both sides

7^x=95

log7^x=log95\\\\\\xlog7=log95\\\\\\x=\frac{log95}{log7} \\\\\\x=2.340
