Malia works at a movie theater and is paid hourly. One month, she earned $388.80. The total amount she earns can be found using

AlekseyPX

Answer:

Malia's unit rate is greater than Bill's by $0.05.

Step-by-step explanation:

Consider the provided information.

The total amount she earns can be found using the equation y = 8.1x, where x is the number of hours she works and y is the total amount she earns in dollars.

The unit rate, when written as a fraction, has a denominator equal to one.

The unit price of Malia is $8.1

For Bill works:

Number of hours Total amount earned

18 $144.90

28 $225.40

35 $281.75

Unit price would be:

\begin{gathered}\dfrac{144.90}{18}=\dfrac{y}{x}\\\\8.05=\dfrac{y}{x}\\\\y=8.05x\end{gathered}

18

144.90

=

x

y

8.05=

x

y

y=8.05x

Hence, unit price of Bill is $8.05

Malia's unit rate is 8.1 whereas Bill's unit rate is 8.05,

Thus, Malia's unit rate is greater than Bill's by 8.10-8.05=0.05.

If a farmer gets 340 bushels of corn from 2 acres of land, how many bushels can they get from 15 acres?

kari74 [83]

The number bushels they get from 15 acres of land is 2550

Solution:

Given that, farmer gets 340 bushels of corn from 2 acres of land

To find: Number bushels they get from 15 acres

Let us first find the unit rate, that is we have to find number of bushels from 1 acre of land

From given question,

2 acres of land = 340 bushels of corn

Therefore, for 1 acres of land,

$\text{ number of bushels from 1 acre of land } = \frac{340}{2} = 170$

How many bushels can they get from 15 acres?

So, multiply the number of bushels from 1 acre of land by 15 to get answer

$\text{number of bushels from 15 acre} = \text{ number of bushels from 1 acre } \times 15$

$\text{number of bushels from 15 acre} = 170 \times 15 = 2550$

Thus number bushels they get from 15 acres of land is 2550

6. Using the discriminant, determine the value of k that will give 1 solution (i.e. discriminant equals zero) y = kx²-4x + 4

Gwar [14]

Answer:

k = 1

Step-by-step explanation:

Discriminant

$b^2-4ac\quad\textsf{when }\:ax^2+bx+c=0$

$\textsf{when }\:b^2-4ac > 0 \implies \textsf{two real roots}$

$\textsf{when }\:b^2-4ac=0 \implies \textsf{one real root}$

$\textsf{when }\:b^2-4ac < 0 \implies \textsf{no real roots}$

As we need to determine the value of k that will give one solution, set the discriminant to zero.

Given equation:

$y=kx^2-4x+4$

Therefore:

a = k
b = -4
c = 4

Substitute these values into the discriminant and solve for k:

$\begin{aligned}b^2-4ac & = 0\\\implies (-4)^2-4(k)(4) & = 0\\16-16k & = 0\\16k & = 16\\\implies k & = 1\end{aligned}$

if the midpoint is located at (6,-2) and one endpoint is at (1,7), what is the coordinates of the other endpoint?

Sladkaya [172]

Answer:

(11, -11)

Step-by-step explanation:

The coordinates of the midpoint are the average of the endpoint coordinates.

6 = (x + 1) / 2

x = 11

-2 = (y + 7) / 2

y = -11
