Answer:

The nth term is 3n+2.

The given sequence is in A.P.

Here,

First term,a= 5

Common difference,d= 3

Therefore the nth term = a+(n-1)d =5+(n-1)3

=5+3n-3 =3n+2.

For the given triangles △YPM∼△WBE, the length of BE is,  22.86 in.

What is similarity of triangles?

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"

Given that,

The triangle, △YPM

Another triangle, △WBE

Triangle △YPM and △WBE similar,

So,  △YPM∼△WBE

And it is known that

for similar triangles, ratio of lengths of sides are equal for similar triangles

so, PM/PY = BE/BM

⇒ 32/15 = BE/21

⇒    BE  =  22.86

Hence, the length of side BE is 22.86 in.

Answers

Answer:

Step-by-step explanation:

6(g-3)=12

6g-18 = 12

6g = 30

g = 5

Answer:

g = 5

Step-by-step explanation:

→ Expand the bracket

6g - 18 = 12

→ Add 18 to both sides to isolate 6g

6g = 30

→ Divide both sides by 6 to isolate g

To get the area of the badgers in yards, you would have to do 40 yds * 20 yds / 2. Your answer should be 400 yds. Then, you would change it into feet. For every one yard, it is three feet. Therefore you would multiply the 400 yds by 3 to get it into feet. Now that you have it into feet, you can multiply it by the number of 1.25 per square feet.

400 ft * 1.25 =1500.

Step-by-step explanation:

The triangle shown is right angles where;

opposite side = x

adjacent side = 8

Angle of elevation = 39°

Using TOA trigonometry identity

tan 39° = opp/hyp

tan 39° = x/8

x = 8tan39°

x = 6.48

Hence the value of x is 6.5 to the nearest tenth

Five more than three times a number is twenty-six. What is the number

Answer:

x=7

The required number is 7.

What are linear equation?

A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.

Now it is given that, Five more than three times a number is twenty-six.

Let the number be x.

So, Five more than three times a number = 5 +3x

and this is equal to 26

So, the required equation we get,

5 +3x = 26

Subtracting 5 both the side we get,

5 +3x - 5 = 26 - 5

Solving we get,

3x = 21

Dividing both the side by 3 we get,

x = 7

Hence the number is 7.

The half-life of a certain radioactive substance is 14 days. There are 6.6 grams of the substance
present initially. Which equation represents the number of grams of the radioactive substance
on day 42?

Answers

Answer:

A(t) = 0.825 g

Step-by-step explanation:

To solve this for amount remaining, we will use the equation;

A(t) = A_o × (½)^(t/t_½)

We are given;

Initial amount; A_o = 6.6 g

Half life; t_½ = 14

Time elapsed; t = 42

A(t) is amount of substance remaining

Thus;

A(t) = 6.6 × (1/2)^(42/14)

A(t) = 6.6 × (1/2)³

A(t) = 6.6 × ⅛

A(t) = 0.825 g
