Answer:

Option: A is correct.

A) a part of a line that has one endpoint and extends indefinitely in one direction

Step-by-step explanation:

" A ray is a line that starts at a given point and goes off for ever in some direction. It may pass through another point as it does so "

Hence, option A is correct.

( The definition of Ray is:

A) a part of a line that has one endpoint and extends indefinitely in one direction )

What is the solution to the system? 1. x-y + 2 z = -7 2. y + z =1 3. x-2 y - 3 z = 0

kvv77 [185]

You'd find this problem easier to understand and do if you'd please list the defining equations vertically and line up variables:

1. x - 1y + 2 z = -7

2. y + 1z = 1

3. x - 2 y - 3 z = 0 Now eliminate the line numbers:

x - 1y + 2 z = -7

1y + 1 z = 1

x - 2 y - 3 z = 0

Let's use the elimination method to eliminate variable z: Seeing that z = 1 - y, we transform the first equation into 1x - 1y + 2(1-y) = -7

and the third into x - 2y - 3(1-y) = 0.

Simplifying 1x - 1y + 2(1-y) = -7

and x - 2y - 3(1-y) = 0,

we get

1x - 2y - 3 + 3y) = 0 and 1x - 1y + 2 - 2y = -7

which in turn simplify to

1x + y = 3 and 1x - 3y = -9

Having eliminated the variable z, we now focus on eliminating x. Mult. the 1st equation by -1, obtaining -1x - 1y = -3. Add this result to 1x - 3y = -9:

0 - 4y = -12, which tells us that y = 3. Subbing 3 for y in 1x + 1y = 3 tells us that x = 0.

All we have left to determine is the vaue of z.

Borrowing Equation 3, from above, we get x - 2 y - 3 z = 0, and into this equation we substitute x = 0 and y = 3: 0 -2(3) - 3z = 0.

Thus, -3z = 6, and z = -2.

The solution set is (0, 3, -2). You should check this by substitution.

51% of the tickets sold at a school carnival were early-admission tickets. If the school sold 100 tickets in all, how many early

saul85 [17]

Answer:

51 were the total number of the tickets sold at a school carnival were early-admission tickets.

Step-by-step explanation:

Total number of tickets sold by = 100

Let $x$ be the early-admission tickets sold by the school.

As 51% of the tickets sold at a school carnival were early-admission tickets.

$x=\frac{51}{100}\times 100$

$= 51$

Therefore, 51 were the total number of the tickets sold at a school carnival were early-admission tickets.

Which of the following is the solution to the system of equations?

drek231 [11]

Answer:

B (3/4,5/4)

Step-by-step explanation:

y = 2- x

$\frac{5}{4} = 2 - \frac{3}{4}$

y = 3x - 1

$\frac{5}{4} = 3 \times \frac{3}{4} - 1$

$\frac{5}{4} = \frac{9}{4} - \frac{4}{4}$

Hope this helps ^-^

Tobi Foods grocery began the year with 300 boxes of cookies with a unit cost of $1.89. During the year, the following additional

Flura [38]

we know that

The first-in-first-out method (FIFO), states that the earliest costs (first costs) are assigned to cost of goods sold and the remaining costs (the more recent costs) are assigned to ending inventory.

The FIFO method assumes that the earliest-goods purchased are sold first.

in this problem

Part a) cost of ending inventory

Find the total cost

Total cost=200*$2.1+400*$2.2+250*$2.4=$1,900

Find the cost of ending inventory

475-250=225 boxes

Cost of ending inventory=225*$2.20+250*$2.40=$1,095

therefore

the answer Part a) is

The cost of ending inventory is $1,095

Part b) cost of goods sold

we know that

The cost of goods sold is equal to the total cost minus the cost of ending inventory

cost of goods sold=$1,900-$1,095=$805

therefore

the answer part b) is

The cost of goods sold is $805
