kodGreya [7K]3 years ago
3 0

Answer:

The sentence written as an equation is 3x + 2 = 17

The solution is x = 5

Step-by-step explanation:

First, create the equation

2 more than 3 times a number x can be represented by 3x + 2

Set this equal to 17, to get the equation 3x + 2 = 17

Now, solve for x:

3x + 2 = 17

3x = 15

x = 5

So, the sentence written as an equation is 3x + 2 = 17

The solution is x = 5

Suppose a triangle has two sides of length 2 and 5 and that the angle between these two sides is pi/3. What is the length of the
patriot [66]
We are given two sides of a triangle that are 2 and 5 and the angle between them is pi/3 or 60 degrees. In this case, we can use the cosine law to relate the given dimensions and angle. The cosine rule goes c2 = a2 + b2 - 2abcos C; Substituting, c2 = 4 + 25 - 2*2*5*cos pi/3 ; c2 = 19; c = sqrt 19 = 4.36 units.

What is the difference in area covered by a single 3 inch windshield wiper operating with a central angle of 138 degrees compare
Elena-2011 [213]

Answer:

38.9 square inches.

Step-by-step explanation:

We are asked to find the difference in area covered by a single 3 inch windshield wiper operating with a central angle of 138 degrees compared to a pair of 5 inch wipers operating together each having a central angle of 114 degrees.

We will use area of sector formula to solve our given problem as:

\text{Area of sector}=\frac{\theta}{360}\times \pi r^2, where, r represents radius and theta represents central angle.

Let us find area of sector with central angle 140 degree and radius 3 inch.

\text{Area of sector}=\frac{138}{360}\times \pi (3)^2

\text{Area of sector}=\frac{138}{360}\times 9\pi

\text{Area of sector}=10.83849

Now, we will find area of sector with central angle 114 degree and radius 5 inch and multiply by 2 as:

\text{Area of sector}=2(\frac{114}{360}\times \pi (5)^2)

\text{Area of sector}=2(\frac{114}{360}\times 25\pi)

\text{Area of sector}=\frac{114}{360}\times 50\pi

\text{Area of sector}=49.74188

Let us find difference of area as shown below:

\text{Difference of areas}=49.74188-10.83849

\text{Difference of areas}=38.90339

\text{Difference of areas}\approx 38.9

Therefore, the difference in area covered is approximately 38.9 square inches.
