Sara can type 90 words in 4 minutes.About how many words would you expect her to type in 10 minutes?

1 answer:

3 0

90 words in 4 minutes is the same as 45 words in 2 minutes because you divide both sides by 2. 2 goes into 10, 5 times, so 45x5=225.
You can expect her to type 225 words in 10 minutes.

11. Little Sally Walker has a choice between going to an in-state college where she would pay

nalin [4]

Answer:

Step-by-step explanation:

Lets calculate first for in state college

yearly tuition fees = $3,500

monthly living expense = $700

one year has 12 months so yearly living expense =$700 * 12 = $8,400

Yearly expense of the in state college = yearly tuition fees ($3,500 )+ yearly living expense($8,400) = $3,500 + $8,400 = $11,900

____________________________________________________

Lets calculate first for out of state college

yearly tuition fees = $6,000

monthly living expense = $400

one year has 12 months so yearly living expense =$400 * 12 = $4,800

Yearly expense of the out of state college = yearly tuition fees ($3,500 )+ yearly living expense($8,400) = $6,000 + $4,800 = $10,800

What is the volume, in cubic cm, of a cylinder with a height of 8cm and a base radius of 7cm, to the nearest tenths place?

FromTheMoon [43]

Answer:

Volume of the cylinder = $1230.88\,cm^3$

Step-by-step explanation:

Height(h) of the cylinder = $8 cm$

Radius(r) of the base= $7cm$

Volume of a cylinder is:

= $\pi \times r^2\times h$

As,

$\pi =\dfrac{22}{7} = 3.14$

Putting the values in the formula:

Volume is:

$=3.14\times(7\times7)\times8\\\\=3.14\times49\times8\\\\=3.14\times392\\\\=1230.88\,cm^3$

The volume of the cylinder is : $1230.88\,cm^3$
