Darpana solved the equation s = StartFraction a + b + c Over 3 EndFraction for a. Her steps are shown below: 1. Multiply by 3: s = StartFraction a + b + c Over 3 EndFraction. 3 s = a + b + c. 2. Subtract b: 3 s minus b = a + b + c minus b. 3 s minus b = a + c. 3. Divide by c: StartFraction 3 s minus b Over c EndFraction = a. Which statement about Darpana's work is true? In step 1 she needed to divide by 3 rather than multiply. In step 2 she needed to add b rather than subtract. In step 3 she needed to subtract c rather than divide. Darpana solved the equation correctly.

Answers

Answer 1

Answer:

Option (c) is correct.

Step-by-step explanation:

Given equation is :

[tex]s=\dfrac{a+b+c}{3}[/tex]

The equation can be solved for a as follows :

Step 1.

Cross multiply the given equation

[tex]3s=a+b+c[/tex]

Step 2.

Now subtract b on both sides

3s-b = a+b+c-b

3s-b = a+c

Step 3.

Subtract c on both sides

3s-b-c=a+c-c

⇒ a=3s-b-c

The statement that is true for Darpana is " In step 3, she needed to subtract c rather than divide".

Which of the following is the sum of all the odd integers between 5 and 102?
A. 2592
B. 2597
C. 2601
D. 2603

Answers

Answer:

2601

Step-by-step explanation:

The integers between 5 and 102 are

7, 9, 11, 13, 15, 17,19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99, 101

The sum of the odd intergers between 2 and 105 can be calculated as follows

= (N + 1/2)^2

= (101 + 1 /2) ^2

= (102/2)^2

= 51^2

= 2601

Hence the sum of the odd intergers between 5 and 102 is 2601

B. All angles of the triangle has the same measure

D, it is a right triangle

E. None of the sides of the triangle have the same length

F. None of the angles of the triangle have the same measure

Answers

Answer:

c e f

Step-by-step explanation:

C. All rotations take one half of the triangle to the other half of the triangle

E. None of the sides of the triangle have the same length

F. None of the angles of the triangle have the same measure

If a shape has a rotation symmetry, then the shape will look exactly the same after rotation. The conclusions to reach for a triangle that has a rotation symmetry are:

A. All sides of the triangle have the same length

B. All angles of the triangle has the same measure

Of all kinds of triangle, only an equilateral triangle has a rotational symmetry.

This means that:

All sides of the triangle must be the sameAll angles of the triangle must be the sameThe complete length of each side are rotated (not half).

The above points imply that: options (a) and (b) are true

Samuel needs 332 feet of wood to build a fence. The wood comes in lengths of 15 feet.

How many total pieces of wood will Samuel need? Theresa needs twice as many feet of wood as Samuel. How many pieces of wood does Theresa need?

Answers

Answer:

23 and 45

Step-by-step explanation:

This is really just a simple division question.  All we have to do to solve the first half is divide 332 by 15:

[tex]332 / 15 = 22.133333333[/tex]

We'll want to round that up to 23, because it seems they're asking for integers here.

For the next part of the question, all we have to do is double the result of the last operation and round that number up as well:

[tex]22.13333333 *2 = 44.2666667[/tex]

Which rounded gives us 45.

Hope this helps!

Answer:

Samuel will need 23 pieces of wood.

Theresa will need 46 pieces of wood.

Step-by-step explanation:

To find how many total pieces Samuel will need, we have to divide 332 feet into 15, since each piece of wood is equivalent to 15 feet:

[tex]332[/tex] ÷ [tex]15=22.1333[/tex]

Samuel can't have a portion of wood, the wood pieces he has must be represented as a whole number. We have to round up to 23 pieces of wood.

Samuel will need 23 pieces of wood to build his fence.

_

If Theresa needs twice as many feet as wood, we have to multiply Samuel's pieces of wood by its length (15 feet):

[tex]23[/tex] × [tex]15=345[/tex]

Multiply [tex]345[/tex] by 2:

[tex]345[/tex] × [tex]2=690[/tex]

Now, divide [tex]690[/tex] by [tex]15[/tex]:

[tex]690[/tex] ÷ [tex]15[/tex]

[tex]=46[/tex]

Theresa will need 46 pieces of wood.

Now move points E and F around to change the orientation of the transversal. Be sure that point F does not cross and that point E does not cross . Do the relationships among the angles that you studied in questions 2 through 4 change when you change the transversal? If so, how?

Answers

Answer:

NO

Step-by-step explanation:

Pairs of alternate interior angles remain congruent, pairs of alternate exterior angles remain congruent, and pairs of same-side interior angles remain supplementary when the transversal is changed.

Pairs of alternate interior angles remain congruent, pairs of alternate exterior angles remain congruent, and pairs of same-side interior angles remain supplementary when the transversal is changed.

What are the interior angles about?

When a transversal intersects two parallel lines, the same-side interior angles formed on the same side of the transversal are supplementary (their measures add up to 180 degrees). If the transversal or lines are altered and are not parallel, the supplementary relationship between same-side interior angles is no longer maintained.

In summary, these angle relationships only hold true specifically for parallel lines intersected by a transversal. If the transversal or the lines change, these angle relationships may no longer remain valid.
