A Wooden board is leaning against the house the base of the board is 10 feet from the base of the house and the base of the board forms a 35° angle with the ground what is the length of the wooden board

Answers

Answer: 12.20 feet.

Step-by-step explanation:

Observe in the figure attached that a right triangle is formed.

Then, you  need to remember the identity:

cos\alpha=(adjacent)/(hypotenuse)

In this case you can identify that:

adjacent=10\nhypotenuse=x

\alpha=35\°

Then, to find the length of the wooden board (x), you need to substitute values and solve for x.

Therefore, you get:

cos(35\°)=(10)/(x)\n\n(x)(cos(35\°))=10\n\nx=(10)/(cos(35\°))\n\nx=12.20

The length of the wooden board is: 12.20 feet.

13 POINTS.+Betsey is 11 years older than Waldo. Betsey's age is 15 years less than three times Waldo's age. The system below models the relationship between Betsey's age (b) and Waldo's age (w):

b = w + 11
b = 3w − 15


Which of the following methods is correct to find Betsey's and Waldo's age?
Solve w + 11 = 3w − 15 to find the value of w.
Solve b + 11 = 3b − 15 to find the value of b.
Write the points where the graphs of the equations intersect the x-axis.
Write the points where the graphs of the equations intersect the y-axis.

Answers

Answer:

Option 1st is correct

Solve w + 11 = 3w − 15 to find the value of w.

Step-by-step explanation:

Here b represents the Betsey's age and w represents the Waldo's age

As per the statement:

Betsey is 11 years older than Waldo. Betsey's age is 15 years less than three times Waldo's age.

The system below models the relationship between b and w:

b = w+11  

b = 3w-15

Equate these equations to solve for w, we have;

w+11 = 3w-15

Add 15 to both sides we have;

w+26= 3w

Subtract w from both sides we have;

26= 2w

Divide both sides by 2 we have;

13 = w

or

w = 13 years

Substitute in b = w+11 we have;

b = 13 +11 = 24 years.

b = 24 years

Therefore. following methods is correct to find Betsey's and Waldo's age is:

w+11 = 3w-15

w + 11 = 3w - 15 \n 2w=26 \n w=13 \n  b = w + 11 \n  b = (13) + 11=24

Simplify the expression. (8x + 14) + (9x - 5)

Answers

use the associative property that says
a+(b+c)=(a+b)+c
and the commutative property that says
a+b=b+a
use together and get
(8x+14)+(9x-5)=8x+9x+14-5
add like terms
8+9=17
therefor
17x+14-5
14-5=9
17x+9 is the simpliefid form

Rename fraction 2/5 so you can add it to 11/25. Find the sum.

Answers

The sum is 21/25.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

2/5

This can be written as,

Multiply 5 on both the numerator and denominator.

= 2 x 5 / 5 x 5

= 10/25

Now,

10/25 + 11/25

= (10 + 11) / 25

= 21 / 25

Thus,

The sum is 21/25.
