Answer:

x ≈ 11.5

Step-by-step explanation:

Since the triangle is right use the sine ratio to solve for x

sin35° = \frac{opposite}{hypotenuse} = \frac{AB}{AC} = \frac{x}{20}

Multiply both sides by 20

20 × sin35° = x, hence

x ≈ 11.5 ( nearest tenth )

Answer: x=8.56365

Step-by-step explanation:

You have the angle and hypotenuse and have to find the opposite so you use sin.

Sin#=o/h

Sin35=o/20

Then I just put that into my calculator and got x= 8.56365. (I added the decimals cause idk what you need to round to)

Betsy can clean a b of the house in an hour. How long will it take her to clean the whole house?
kipiarov [429]

Answer:

\frac{b}{a} is the total time taken to clean the house.

Step-by-step explanation:

Given that:

Betsy cleans \frac{a}{b} of the house.

Time taken = 1 hour

To find:

Time taken to clean the whole house = ?

Solution:

We can use unitary method here to solve this problem.

We are given that \frac{a}{b} of the house is cleaned in 1 hour.

We have to find that a total of 1 house will be cleaned in how much time.

(1 house because Betsy's house can be considered as a single unit).

To find this we will divide 1 hour with \frac{a}{b}.

Now, Let us solve this mathematically:

\frac{a}{b} of the house is cleaned in = 1 hour

1 of the house will be cleaned in =  1 hour divided by \frac{a}{b}

\dfrac{1}{\dfrac{a}{b}}\ hours\\\Rightarrow \dfrac{1 \times b}{a}\ hours\\\Rightarrow \dfrac{b}{a}\ hours

So, the <em>answer </em>is:

\frac{b}{a} is the total time taken to clean the house.

-2x + y=5 and -5x + y = -4 cooridbnates of the solution to this system of equation
Viktor [21]

Answer:

(3,11)

Step-by-step explanation:

Turn both equations into linear equations:

y=2x+5

y=5x-4

Then, just graph both equations.

Find the point where the two lines intersect. That point of intersection is  the solution. That coordinate is (3,11).

The distance between (2,7) and (14,12)
Artist 52 [7]

Answer:

Distance = 13

Step-by-step explanation:

A(2,7)  B(14,12)

                     D = √((14-2)² + (12-7)²)

                     D = √(12² + 5²)

                     D = 13
