Answer:

The area of the rectangle ABCD is \frac{2}{5} square units.

Step-by-step explanation:

From statement we have that rectangle ABCD is formed by the following points: A(x,y) = (2, 5), B(x,y) = \left(\frac{8}{3}, 5 \right), C(x,y) = \left(\frac{8}{3}, \frac{28}{5}  \right), D(x,y) = \left(2, \frac{28}{5} \right). First, we calculate the length of each side by the Pythagorean Theorem:

AB = \sqrt{\left(\frac{8}{3}-2 \right)^{2}+ (5-5)^{2}}

AB = \frac{2}{3}

BC = \sqrt{\left(\frac{8}{3}-\frac{8}{3}\right)^{2}+\left(\frac{28}{5}-5\right)^{2} }

BC = \frac{3}{5}

CD = \sqrt{\left(2-\frac{8}{3} \right)^{2}+\left(\frac{28}{5}-\frac{28}{5}  \right)^{2}}

CD = \frac{2}{3}

DA = \sqrt{\left(2-2\right)^{2}+\left(5-\frac{28}{5} \right)^{2}}

BC = \frac{3}{5}

Which satisfies all minimum characteristics for a rectangle. The area of the rectangle ABCD is the product of its base and its height, that is:

A = \left(\frac{2}{3}\right)\cdot \left(\frac{3}{5} \right)

A = \frac{2}{5}

The area of the rectangle ABCD is \frac{2}{5} square units.

Help please i am stuck on what to do
nikklg [1K]

Answer:

These are confusing Beth , b/c you have to remember that they will add to 100%

Step-by-step explanation:

so

green = 3*  yellow

100% = green + yellow + 35% + 25%

100% = 3* yellow + yellow +60%

40% = 4* yellow

10% = yellow

30% = green

there are 14 purples in the bag , which is 35% of total

14/.35 = 40

there are a total of 40 pins

so

4    are yellow  (10% of 40  or 40* 0.1)

12 are green    (30% of 40  or 40*0.3)

14  are purple  (35% of 40 or 40*0.35)

10  are grey  (25% of 40  or 40*0.25 )

Write the equation in standard form<br><br> y = -10x + 6
Mumz [18]
Step (1) Flip the equation

−10x+6=y


Step (2) Add -6 to both sides

−10x+6+−6=y+−6

−10x=y−6

Step (3) Divide both sides by -10

−10x−10=y−6−10

ANSWER
x =  \frac{ - 1}{10} y +  \frac{3}{5}

Help please ill give brainliest answer
mihalych1998 [28]

Answer:

ΔLMN ≅ ΔLQP by (SAA)

Step-by-step explanation:

It is given that line (NM) is congruent to the line (PQ), meaning they have the same measure. This is signified by the small red line on each of these sides.

Moreover, it is also given that angle (MNL) is congruent to angle (QPL), this is shown by the red arc around these angles.

Finally one can figure out that angle (NLM) is congruent to angle (PLQ) by the vertical angles theorem. The verticle angles theorem states that when two lines intersect, the opposite angles are congruent.

Thus the two triangles are congruent by side-angle-angle postulate, abbreviated as (SAA).

0.4 is 10 times as much  as ?
dimulka [17.4K]
<span>0.4 is 10 times as much  as ? for answering this, we put x an unknown number such that 0.4 is 10 times as much  as x, so it does mean 0.4 =10x, so for finding the value of x, we divids 0.4 by 10, x= 0.4/10=0.04. the answer is 0.4 is 10 times as much  as 0.04Hope this helps. Let me know if you need additional help!</span>
