The slope is 2/3

Step-by-step explanation:

you need to use the equation y=rise over run, so the equation would be 2-4 over -2-1 and that would equal 2/3 and to graph you just need to find the y-intercept and put it together with the slope y=2/3+b

Simple interest formula:

Total = start value x (1 + (rate x time))

Total = 13,000 x (1 + (0.047 x 6))

Total = 13000 x 1.282

Total = £16,666

Given:

The measure of the first angle is 40° less than the measure of the second.

To find:

The measures of the complementary angles that satisfy the given condition.

Solution:

Let the measure of first angle be x°.

According to the given condition,

First angle = Second angle - 40°

[tex]x^\circ =\text{Second angle}-40^\circ [/tex]

Add 40° on both sides.

[tex](x+40)^\circ =\text{Second angle}[/tex]

We know that, sum of complementary angles is 90°. So,

First angle + Second angle = 90°

[tex]x^\circ +(x+40)^\circ =90^\circ [/tex]

[tex]2x^\circ +40^\circ =90^\circ [/tex]

[tex]2x^\circ =90^\circ -40^\circ [/tex]

[tex]2x^\circ =50^\circ [/tex]

Divide both sides by 2.

[tex]x^\circ =25^\circ [/tex]

So, the measure of first angle is 25°.

[tex](x+40)^\circ =(25+40)^\circ =65^\circ[/tex]

So, the measure of second angle is 65°.

Answer:

Ans B should be correct.

Complete question is;

Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units. From the net, we can see that there are six equal faces and so we get the total surface area is 6 × 16 = 96 square units.

Find the total surface area of the rectangular prism attached.

Answer:

72 cm²

Step-by-step explanation:

From the rectangular prism attached, we can see that it has 6 sides.

Now, each side has a mirrored part which is of same dimensions with it.

Thus, unfolding to get a net, we have;

2 faces with dimension: 3cm × 6cm

2 faces with dimension: 2cm × 6 cm

2 faces with dimension: 2cm × 3cm

Thus,total surface area is;

2(3cm × 6cm) + 2(2cm × 6cm) + 2(2cm × 3cm) = 36 + 24 + 12 = 72 cm²

Among all there is no condition which will not create a gap or an overlap at a vertex of polygon.

A polygon is a plane figure that is having finite number of sides which are connected to form a closed figure.

In this we have two cases:

case 1: If the polygons are regular.

The sum of all the angles is equal to 360°.

For example: Consider a quadrilateral polygon whose four sides are congruent and each angle is 90°. Then the sum of angles is 90+90+90+90=360°.

case 2: If the polygons are not regular

We know that sum of angles can be found by (n-2)*180°

Suppose polygon is 3 sided so the sum will be (3-2)*180=180° which is less than 360°.

Suppose polygon is 6 sided so the sum will be (6-2)*180°=720° which is greater than 360°.

Hence there is no condition which will not create a gap or an overlap at a vertex of polygons.
