333 erasers cost \$4.41$4.41dollar sign, 4, point, 41. Which equation would help determine the cost of 444 erasers? Choose 1 ans

Rudiy27

Answer:

Option D will be correct.

Step-by-step explanation:

The 333 erasers cost $4.41.

We have to determine the cost of 444 erasers.

Let the price of 444 erasers is $x.

Therefore, since the number of erasers cost per dollars is constant, hence the equation that would help to determine the cost of 444 erasers will be $\frac{333}{4.41} = \frac{444}{x}$

⇒ $\frac{3}{4.41} = \frac{4}{x}$

Therefore, option D will be correct. (Answer)

John is interested in purchasing a multi-office building containing five offices. The current owner provides the following proba

Elenna [48]

Answer:

Option B.

Step-by-step explanation:

The given table is:

Number of Lease Offices : 0 1 2 3 4 5

Probability : 5/18 1/4 1/9 1/18 2/9 1/12

The expected probability is

Expected probability = $\sum_{i=0}^5 x_{i}p(x_i)$

Expected probability = $0p(0)+1P(1)+2P(2)+3P(3)+4P(4)+5P(5)$

Expected probability = $0\cdot (\frac{5}{18})+1\cdot (\frac{1}{4})+2\cdot (\frac{1}{9})+3\cdot (\frac{1}{18})+4\cdot (\frac{2}{9})+5\cdot (\frac{1}{12})=\frac{35}{18}$

It is given that the yearly lease = $12,000.

The yearly leases for the whole building in a given year is

Yearly leases = $\frac{35}{18}\times 12000=23333.3333333\approx 23333.33$

Therefore, the correct option is B.

At the movie theatre, child admission is $6.40 and adult admission is $9.70. On Monday, 155 tickets were sold for a total sales

Molodets [167]

Less than or equal to 121 adult tickets.

You would do 1180.10/9.70

Which equals 121

Since we don't know how many children tickets were, sold it could be less than or equal to 121.

PLZZZZZZZ HELPP Which ordered pair is the solution to the system of equations? {y=2x−15} {4x+3y=−5} (5, −5) (4, −7) (0, 6) (7

Sophie [7]

solution is (4, - 7 )

given the equations

y = 2x - 15 → (1)

4x + 3y = - 5 → (2)

substitute y = 2x - 15 into (2)

4x + 3(2x - 15) = - 5

4x + 6x - 45 = - 5

10x - 45 = - 5 ( add 45 to both sides )

10x = 40 ( divide both sides by 10 )

x = 4

substitute x = 4 into (1) for corresponding value of y

y = (2 × 4 ) - 15 = 8 - 15 = - 7

solution is (4, - 7 )

Jimmy is selling bracelets for $1.50. So far she has earned $120. She needs to earn more than $135 in order to meet her goal. Ho

Tema [17]

Selling 90 would reach her goal of $135 so she would need to sell 91 to exceed her goal

135/1.5=90 so 91*1.5=136.5
