Mathematics

Furkat [3]3 years ago

Answer: The value of y is 34 and the correct option is B.

Explanation:

It is given that ABCD is a parallelogram.

From the given figure it is noticed that,

\angle DAB=76^{\circ}

\angle ABC=3y^{\circ}

According to the properties of parallelogram the consecutive angles of parallelogram are supplementary angles and their sum is 180 degree.

From the figure it is noticed that the angle DAB and angle ABC are consecutive angles of the parallelogram.

\angle DAB+\angle ABC=180^{\circ}

76+3y=180

3y=180-76

3y=102

y=34

Therefore the value of y is 34 and option B is correct.

In a parallelogram, consecutive angles are supplementary.

3y + 78 = 180

3y = 102

y = 34

Two similar triangles have have areas of 75 m2 and 12 m2. find the ratio of the perimeters
soldi70 [24.7K]

we know that having similar triangles so the ratio of sides,area and volume are same.

s/s=s^2/s^2

we know that s^2 will be the area of triangle.

s^2/s^2=75/12

so s/s=\sqrt{75/12}

so the ratio of the perimeter of two triangles will be

(s+s+s)/(s+s+s)=(\sqrt{75} +\sqrt{75} +\sqrt{75} )/(\sqrt{12}+\sqrt{12} +\sqrt{12} )

ratio of the perimeter=\sqrt{225} /\sqrt{36}

What is a35 for the arithmetic sequence presented in the table below?
Kryger [21]

Answer: choice B) a35 = -118

=====================================================

Explanation:

When n = 5, an = 32 as shown in the first column of the table. This means the fifth term is 32. Plug in those values to get

an = a1+d(n-1)

32 = a1+d(5-1)

32 = a1+4d

Solve for a1 by subtracting 4d from both sides

a1 = 32-4d

We'll plug this in later

Turn to the second column of the table. We have n = 10 and an = 7. Plug those values into the formula

an = a1+d(n-1)

7 = a1 + d(10-1)

7 = a1+9d

Now substitute in the equation in which we solved for a1

7 = a1+9d

7 = 32-4d+9d ... replace a1 with 32-4d

7 = 32+5d

5d = 7-32

5d = -25

d = -25/5

d = -5

This tells us that we subtract 5 from each term to get the next term.

Use this d value to find a1

a1 = 32-4d

a1 = 32-4*(-5)

a1 = 32+20

a1 = 52

The first term is 52

--------------

The nth term formula is therefore

an = 52 + (-5)(n-1)

which simplifies to

an = -5n + 57

To check this result, plug in n = 5 to find that a5 = 32. Similarly, you'll find that a10 = 7 after plugging in n = 10. I'll let you do these checks.

--------------

Replace n with 35 to find the 35th term

an = -5n + 57

a35 = -5(35) + 57

a35 = -175 + 57

a35 = -118

If you divide the total distance traveled on a car trip (as determined by the odometer) by the elapsed time of the trip, are you
PSYCHO15rus [73]

In general, you're calculating the magnitude of average velocity. In fact, speed is a vector, and as such it also has a direction and orientation.

So, if you compute the average speed, you're assuming that you went directly from point A to point B, which is basically never the case.

If, instead, you actually moved on a straight line from point A to point B, then the two quantities are the same.
