That's an easy parallelogram, parallel to the x axis. Let's label the points

A(-4,-1),B(-2,4),C(4,4),D(2,-1)

AD and BC are the sides parallel to the x axis. We'll call those the base, it has length 4 - -2 = 6.

The height is the change in y between the bases, so 4 - -1 = 5.

The area is base times height, 6 × 5 = 30

Answer: 30

The shoelace formula gives us the area of a polygon from 2D coordinates without worrying about the shape:

(-4,-1),(-2,4),(4,4),(2,-1)

(-2,4),(4,4),(2,-1),(-4,-1)

A = \frac 1 2 | -4(4) - (-1)(-2) + (-2)(4) - 4(4) + 4(-1) - 4(2) + 2(-1) - (-1)(-4) |

A = \frac 1 2 |-60| = 30 \quad \checkmark

Mikkel pays a 4 percent state income tax on his earnings. If he earns $1,867, how much state income tax can he expect to pay? $4
lisabon 2012 [21]

Answer:

$74.68

Step-by-step explanation:

Convert the percent to a decimal.

4% = 0.04

Multiply his income by the percentage to find the tax.

$1,867 × 0.04 = $74.68

He can expect to pay $74.68.

Help needed ASAP will give BRAINLIEST
grin007 [14]

Answer:

C.

Step-by-step explanation:

Recall that the sum of the (3) interior angles of a triangle <em>must</em> equate to 180.

In other words:

(55)+(20)+(x)=180

Where x is our unknown angle. So, we need to solve for x.

On the left, add 55 and 20:

75+x=180

Subtract 75 from both sides. The left side cancels:

x=105

Therefore, the third angle is 105 degrees.

Our answer is C.

How to find third coordinate when given midpoint and a point?
IgorLugansk [536]
Example : 
u have an endpoint at (6,5)......ad the midpoint is (4,2)....find the other endpoint.

midpoint formula : (x1 + x2) / 2, (y1 + y2) / 2
one endpoint (6,5)....x1 = 6 and y1 = 5
other endpoint (x,y)...x2 = x and y2 = y
sub into the formula
m = (6 + x) / 2, (5 + y) / 2

okay, so the midpoint is (4,2)....so ur x value will equal 4
(6 + x) / 2 = 4...multiply both sides by 2
6 + x = 4 * 2
6 + x = 8
x = 8 - 6
x = 2 <==

midpoint is (4,2)....so the y value will equal 2
(5 + y) / 2 = 2 ...multiply both sides by 2
5 + y = 2 * 2
5 + y = 4
y = 4 - 5
y = -1 <==

so ur other endpoints are (2,-1)

If the mass of a material is 44 grams and the volume of the material is 6 cm^3, what would the density of the material be?
Svetlanka [38]

Density is mass per unit volume.

For the given material that has a mass of 44 grams occupying a volume of 6 cm^3, we divide the mass by the volume, i.e.

density of material = 44 grams / 6 cm^3 = 44/6 grams/cm^3 = 7.3 g/cm^3 (to two significant figures)

Find the value of x.
alukav5142 [94]

Step-by-step explanation:

The sum of the three angles in a triangle must be 180. Since this triangle has a right angle, we know that it is 90°, so the sum of the remaining two angles must be 90.

We can set up an equation for the two remaining angles to determine the value of x:

(x + 28) + x = 90

2x + 28 = 90

2x = 62

x = 31
