A 25ft Ladder Is Leaning Up Against Awall. If The Ladder Makes A 63 Withthe Ground, How Far Is The Base
Answer 2

The distance of the base of the ladder from the wall is 23.01 ft

What are trigonometric identities?

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

We are solving from how far the base of the ladder from the wall and we are representing it as x.

Based on the type of triangle, we are going to use Trigonometry ratios.

We are going to use the cos ratio.

Let opposite be x, base be 25 and theta (angle) be 23.

Cos(23) = x/ 25

Make x the subject;

x = Cos(23)×25

x = 23.0126 ft

Therefore the distance  is 23.01 ft

Your savings account pays 2.5% interest per year. How much interest does the account pay per month.

Answers

Answer:

0.21%

Step-by-step explanation:

2.5/12=0.208 or 0.21

Based on the interest that your savings account pays per year, the interest paid per month is 0.21%.

How much interest is paid per month?

The interest paid per month can be found by dividing the yearly interest by the 12 months of the year.

Therefore, solving gives:

= Annual interest / 12 months

= 2.5% / 12

= 0.21%

In conclusion, this is 0.21%.

Answers

Answer:

Not a valid inference.

Step-by-step explanation:

This is not a valid inference. This is because there may be a slight bias from the classmates he is asking, because, as the question read, he is in math class. Asking math class students if they like math or english more, may have a swayed opinion.

Answer:

No

Step-by-step explanation:

This is a biased survey, due to the fact he only asked his classmates in math. For a unbiased survey, everyone must have an equal chance of being picked.

Answers

Answer:

See attached for a "Neat" quadratic formula.

a = -1

b = 2

c = 1

x = [-2 +- sqr root( 4 -4*-1*1)] / -2

x = [-2 +- sqr root( 4 -4*-1*1)] / -2

x = [-2 +- sqr root(8)] / -2

x1 = (-2 +2.8284271247)  / -2

x1 = .8284271247 / -2

x1 = -0.41421

x2 = (-2 -2.8284271247)  / -2

x2 = ( -4.8284271247)  / -2

x2 = 2.4142135624

So, we can identify this as a transversal, which I will assume you already know what that is. When you have a transversal, you need to follow a certain set of rules, and don't worry, they're very simple.

Angle PSR is a vertical angle of angle OST, which automatically, according to your theorems, postulates, or properties, equal to each other. So with that in mind, you know that STN follows the same rules.

Additionally, where the lines intersect, each corresponding side MUST equal 180 degrees. So to find MTS, all you have to do is 180 minus 73, which gives you 107, completing that line.

A) $21,651.24
B) $65,487.22
C) $45,591.35
D) $12,536.25

Answers

Answer:

A) $21,651.24

Step-by-step explanation:

x = p(1 - r)ⁿ

p = $55000

r = 11%  = 0.11

n = 8 years

x = $55000(1 - 0.11)⁸

= $55000ₓ0.89⁸

= $55000ₓ0.39365888057

= $21651.24

I am going to say that:

x is the number of books that Lindsay owns.

y is the nuber of books that Destiny owns.

z is the number of books that Henry owns.

Lindsay owns one-third the number of books that Destiny owns.

Marla is making a fence to go

Flower garden she planted. The
garden is 5 feet long and 3 feet
wide. How many feet of fencing
does she need?

Answers

Answer:

16 feet of fencing

Step-by-step explanation:

This equation is essentially asking us the perimeter of the fence. If you add 5+3+5+3 you get the sum of 16

Answer:

16 feet

Step-by-step explanation:

She will need to the same amount of fencing as the measurement of her perimeter. To calculate the perimeter, you add length times 2 plus width times 2. 5x2+3x2=16, so the perimeter of the garden is 16 feet meaning she will need 16 feet of fencing :)

I will give you the formula and teach you how to solve this. Let’s start with finding the area of both the right triangles.
The formula is, base x height / 2 = area
Triangle 1 - 2x8/2 = 16/2 = 8
Triangle 2 - 2x8/2 = 16/2 = 8
Rectangle - 8x3 = 24
Add them up: 24 + 8 + 8 = 40 square feet

Answers

Answer:

(a) x = 30°

(b) mRS =  30°

mST =  120°

mTU  = 120°

mUR = 90°

Step-by-step explanation:

(a) In the picture attached, the diagram is shown.

Given that m arc RS = x, from the ratios:

m arc ST = 4x

m arc TU = 4x

m arc UR = 3x

The addition of the four arcs must be equal to 360°, then:

x + 4x + 4x + 3x = 360°

12x = 360°

x = 360°/12 = 30°

(b) m arc RS = x = 30°

m arc ST = 4x = 4*30° = 120°

m arc TU = 4x = 4*30° = 120°

m arc UR = 3x = 3*30° = 90°
