Answer 1

Given:

The figures of triangles and their mid segments.

To find:

The values of n.

Solution:

Mid-segment theorem: According to this theorem, mid segment of the triangle is a line segment that bisect the two sides of the triangle and parallel to third side, The measure of mid-segment is half of the parallel side.

11.

It is given that:

Length of mid-segment = n+8

Length of parallel side = 6n

Using mid-segment theorem, we get

[tex]n+8=\dfrac{1}{2}(6n)[/tex]

[tex]n+8=3n[/tex]

[tex]8=3n-n[/tex]

[tex]8=2n[/tex]

Divide both side by 2.

[tex]\dfrac{8}{2}=n[/tex]

[tex]4=n[/tex]

Therefore, the value of n is equal to 4.

12.

It is given that:

Length of mid-segment = 5n

Length of parallel side = 8n+10

Using mid-segment theorem, we get

[tex]5n=\dfrac{1}{2}(8n+10)[/tex]

[tex]5n=4n+5[/tex]

[tex]5n-4n=5[/tex]

[tex]n=5[/tex]

Therefore, the value of n is equal to 5.

4. If f(x)=2x+3(x+4)+5 then f(6)=?

Answers

Answer:

f(6)=42

Step-by-step explanation:

We know that the equaiton is f(x)=2x+3(x+4). So that means when it is f(6), we plug in 6 into all of the x. Therefore, the equation will be f(6)=2(6)+3(6+4). We combine like terms to get f(6)=12+3(10). We do 3x10 which is equal to 30. f(6)=30+12. 30+12=42. f(6)=42. Therefore, f(6)=42.

If this has helped please mark as brainliest

Answer: 47

Step-by-step explanation:

That just means replace the x’s with 6 in the equation. So 2*6+3(6+4)+5. 6+4 is 10, 2*6 is 12. So the equation is now 12+3(10)+5. 3*10 is 30. 12+30+5=47.

Lydia buys peanut butter in bulk for $0.20 an ounce. How much does 18 ounces of the peanut butter cost? ​

Answers

Answer:

3.6 dollars

Step-by-step explanation:

Lets go over what we know:

Each ounce of penut butter cost 0.2$, or 1/5$

We need 18 ounces.

To solve this, lets multiply the cost per ounce by the amount of ounces:

0.2*18

Or

1/5*18

=

18/5

This can be simplfied into:

3 3/5

We know each 1/5 is 20 cents(0.2), so 3 cents would be 3*0.2 = 0.6:

3.6 dollars

So the answer is for 18 ounces, it cost 3.6 dollars.

Hope this helps!

What is the sum of the of what is the sum of the given arithmetic series?
5 + 8 + 11 + ... + 92
O 1554
O 1545
O 1455
O None of these

Answers

Answer:

3rd option : 1455

Step-by-step explanation:

here, a = 5, d = 3 , tn = 92, n = ?, Sn = ?

tn = [a + (n - 1) d]

92 = [ 5 + (n - 1)d

92 = 5 + 3n - 3

92 - 5 + 3 = 3n

90 = 3n

n = 90/3

n = 30

By sum of first n terms of an A. P formula,

Sn = n/ 2 [ 2a + (n - 1) d]

Sn = 30/2 [ 2 * 5 + (30 - 1) 3]

Sn = 15[ 10 + 29 ( 3) ]

Sn = 15[ 10 + 87 ]

Sn = 15( 97 )

Sn = 15 * 97

Sn = 1455

Therefore, option 3rd 1455 is correct.

C. 7.1

Step-by-step explanation:

Answer:

The probability that a dart thrown at random within the dartboard will hit the bull's eye is 14.1%

Step-by-step explanation:

[tex]The probability is found by dividing the area of the bull's eye by the total area of the dart board:\[\large P(bull's\ eye)=\frac{\pi\ 6^{2}}{\pi\ 16^{2}}=\frac{36}{256}=0.1406\]Therefore your answer of 14.1% is close.[/tex]

What is the area, in square centimeters, of an equilateral triangle with a perimeter of 15 centimeters? Round the answer to the nearest tenth.

Answers

Answer:

A≈10.83cm²

Step-by-step explanation:

Unit Conversion:

P=15cm

Using the formulas

A=3

4a2

P=3a

Solving forA

A=3P2

36=3·152

36≈10.82532cm²

Answer:

10.8 cm^2 to nearest tenth.

Step-by-step explanation:

You can use Hero's formula to do this:

Area = √[s(s-a)(s-b)(s-c)]   where s = semi-perimeter,  a b and c are the lengths of the 3 sides,

Here s = 15/2 = 7.5 and a, b and c = 5.

area = √(7.5 * 2.5 * 2.5 * 2.5)

= √117.1875

= 10.8253.

Another method would be to use trigonometry

h = 5 sin 60 and 1/2 * base = 1/2 * 5 = 2.5

So area = 5 sin60 * 2.5 = 10.8253,

The following tables show some values from three different functions. which of these functions could be quadratic?

Answers

Answer:

C. III only

Step-by-step explanation:

a quadratic function means that as the maximum power in its arguments it is squaring 1 or more items.

so, let's look at the tables.

table I shows the powers of 2. y = 2^x

2^0 = 1

2^1 = 2

2^2 = 4

2^3 = 8

so, it is not saying anything in general.

table II shows an "identity" equation. y = x

0 = 0

1 = 1

2 = 2

3 = 3

this does not square anything.

table III shows then finally a square equation. y = x^2

0^2 = 0

1^2 = 1

2^2 ≈ 4

3^2 = 9
