GrogVix [38]

Answer:

12.5

Step-by-step explanation:

89% of 14= 89/100 x 14

=12.46

Rounded to nearest tenth this is; 12.5

In this context *of* means times(x) and % means /100

Randolph is creating rectangle WXYZ so that WX has an equation of y = 1 over 4x + 4. Segment XY must pass through the point (−2,

Sliva [168]

Answer:

The correct option is;

c.) y - 6 = -4(x - (-2))

Step-by-step explanation:

We note that the figure Randolph is creating is a rectangle, therefore, we have;

$\overline{WX}\perp \overline{XY}$ , therefore, we have;

$\overline{WX} = \dfrac{1}{4} x + 4$

∴ Slope $\overline{WX}$ = 1/4

$\overline{XY}$ must pas through the point (-2, 6)

Given that $\overline{WX}\perp \overline{XY}$ , we have;

$Slope \ \overline{XY} = \dfrac{-1}{Slope \ \overline{WX}}$

$\dfrac{y - 6}{x - (-2)} = -1/\dfrac{1}{4} = -4$

y - 6 = -4(x - (-2))

Therefore, the correct option is c.) y - 6 = -4(x - (-2)).

What is the answer to this math question?

oksano4ka [1.4K]

Answer:

The answer is option 3.

Step-by-step explanation:

First we have to find the area of both rectangle and triangle :

Rectangle,

$area = base \times height$

Let base = 9,

Let height = 3,

$area = 9 \times 3 \\ area = 27 \: {m}^{2}$

Triangle,

$area = \frac{1}{2} \times base \times height$

Let base = 3,

Let height = 3,

$area = \frac{1}{2} \times 3 \times 3 \\ area = \frac{1}{2} \times 9 \\ area = \frac{9}{2} \\ area = 4.5 \: {m}^{2}$

Lastly, in order to find the shaded region you have to substract the area of triangle from the area of rectangle :

$area = 27 - 4.5 \\ area = 22.5 \: {m}^{2}$

Ok. You can use equations to find out what number of each meal was eaten.

x*14+y*17=99

If you solve for x and y (I used guess and check- there's only a few possible combinations) and got one chicken dinner and five steak dinners.

How many solutions does the system of equations shown below have?

rjkz [21]

Answer:

one solution with a y value of 5

Step-by-step explanation:

/| x+y-4 = 0| x-y-6 = 0

We try to solve the equation: x+y-4 = 0

x+y-4 = 0 // - x-4

y = -(x-4)

y = 4-x

We insert the solution into one of the initial equations of our system of equations

We get a system of equations:

/| x+x-6-4 = 0| y = 4-x

2*x-10 = 0 // + 10

2*x = 10 // : 2

x = 10/2

x = 5

We insert the solution into one of the initial equations of our system of equations

For y = 4-x:

y = 4-5

y = -1

We get a system of equations:

/| y = -1| x = 5
