Tisha have 72 books in all.

Step-by-step explanation:

Given,

Number of shelving units = 2

One shelving unit has 3 shelves.

2 shelving units will have = 3*2 = 6 shelves

Books hold by each shelf = 12 books

Books hold by 6 shelves = 12*6 = 72 books

As the shelves are filled with books, therefore,

Tisha have 72 books in all.

Which situation can be modeled by the equation y=3x+25

Gnesinka [82]

For this case we have the following situation:

The monthly cost of a gym in the city is $ 3. The initial registration is $ 25. Write a mathematical expression that models the problem.

So we have to define variables:

x: number of months

y: total cost

The mathematical expression that models the problem is:

$y = 3x + 25$

The circumference of a circular garden is 147.58 feet What is the diameter of the garden? Use 3.14 for and do not round your ans

Stella [2.4K]

Answer:

The diameter is 47

Step-by-step explanation:

Given

$C = 147.58$ --- Circumference

$\pi = 3.14$

Required

Determine the diameter (d)

The circumference of a circle is:

$C = \pi d$

Make d the subject

$d = \frac{C}{\pi}$

$d = \frac{147.58}{3.14}$

$d = 47$

A loaded grocery cart is rolling across a parking lot in a strong wind. You apply a constant force F⃗ =( 35 N )i^−( 37 N )j^ to

Trava [24]

Answer:

-189.8 J

Step-by-step explanation:

We are given that f

Force applied=F=35 Ni-37 Nj

Displacement, s=(-8.7m)i-(3.1m)j

We have to find the work done .

We know that

Work done= $F\cdot s$

Using the formula

Work done= $(35i-37j)\cdot (-8.7-3.1)$

Work done= $-304.5+114.7$

Using $i\cdot i=j\cdot j=k\cdot k=1,i\cdot j=j\cdot i=j\cdot k=k\cdot j=i\cdot k=k\cdot i=0$

Work done=-189.8J

Hence, the work done =-189.8 J
