Effectus [21]2 years ago
7 0

Answer:

C. The number of multiple-choice questions plus the number of

short-answer questions is 15.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of multiple-choice questions

y is the number of short-answer questions.

Multiple-choice questions are worth 2 points, and short-answer questions are worth 5 points.

This means that:

2x + 5y = 60

The test has 15 questions.

This means that:

x + y = 15.

Which means that option C is the correct answer.

A strip mall generates $215,000 in effective rental income and $3,000 in other income. The same mall has $102,000 in operating e
Gnesinka [82]

Answer: $116,000

Step-by-step explanation:

The net operating income will be the operation profit after deducting the expenses from the accrued revenue (reserve exclusive)

The revenue generated are $215,000 + $3,000

= $218,000

Expenses incurred;

$102,000

The net operating income = $218,000 - $102,000

= $116,000

Note that reserves is not used in business operation. Therefore it cannot be regarded either as revenue or expenses.

Which statement is true using Cavalieri’s principles ?
Kay [80]

Answer:

One of the benefits of Cavalieri's principle is that it allows us to determine the volume of an oblique prism (or oblique cylinder). When dealing with two prisms (or two cylinders), if the base areas are equal and the heights are equal, then the volume is V = Bh regardless of the overall shape.

( i cant see the answers well so estimate to the one that applies)

3. A car starts from rest and accelerates uniformly over a time of 6.21 seconds
Klio2033 [76]

We have,

t = 6.21 s

s = 111 m

u = 0 m/s

To determine: "a" of the particle.

We know,

s = ut + ½ at²

⇒ s = ½ at²

⇒ a = 2s/t²

⇒ a = [2(111 m)]/(6.21 s)²

⇒ a = (222 m)/(38.5641 s²)

⇒ a ≈ 5.75 m/s²
