The piano has 422 strings, because 37×6=422.

(Choice B)

The piano has 222 strings, because 37×6=222.

(Choice C)

The piano has 6 strings, because 37÷6=6 remainder 1.

Answer: The piano has 222 strings, because 37×6=222.

Step-by-step explanation:

Since we are informed that Leslie tuned a guitar with 6 strings today and that she then tuned a piano with 37 times as many strings.

This simply means that we have to multiply 37 by 6 strings to get the value of the strings of the piano that she tuned. This will be:

= 6 × 37

= 222 strings.

Leslie tuned 222 strings.

Therefore, the piano has 222 strings, because 37×6=222.

Solve the equation x^2+5x+6=0
gayaneshka [121]

Answer:

x=-3    x=-2

Step-by-step explanation:

x^2+5x+6=0

Factor

What 2 numbers multiply to 6 and add to 5

3*2 =6

3+2=5

(x+3)(x+2) =0

Using the zero product property

x+3 =0   x+2=0

x=-3    x=-2

Answer:

a)19.28≈x (rounded to the nearest hundredth)

b)7.66≈x (rounded to the nearest hundredth)

c)x≈8.39(rounded to the nearest hundredth)

d)x≈36.87 (rounded to the nearest hundredth) and y=5

Step-by-step explanation:

I'm going to first assume that all of these are right triangles.

If you look at the hint, it says SOHCAHTOA

This stands for the trigonometric functions

SOH tells us that sine(θ)=opposite/hypotenuse

CAH tells us that cosine(θ)=adjacent/hypotenuse

TOA tells us that tangent(θ)=opposite/adjacent

(ps. θ, or theta, stands for any angle measure)

Now, let's look at problem a.

We have the value of the hypotenuse and the value of an angle. We want to find the side opposite from the angle. So, in this case, we want to use the sine function.

sin(40)=x/30

30*sin(40)=x

19.28≈x (rounded to the nearest hundredth)

We can solve the other problems in a similar fashion.

Problem b

We have the hypotenuse, an angle measure, and we want to find the adjacent side. This is telling us to use the cosine function.

cos(40)=x/10

10*cos(40)=x

7.66≈x (rounded to the nearest hundredth)

Problem c

We have an angle measure, an adjacent value, and we want to find the opposite length, so we're going to use the tangent function.

tan(40)=x/10

10*tan(40)=x

x≈8.39(rounded to the nearest hundredth)

Problem d

We need to first solve for x, the angle measure.

We have an opposite length, an adjacent length, so we can use the tangent function to solve for the missing angle

Let's set up an equation

tan(x)=3/4

Using tan^{-1} or tangent inverse to cancel out the tangent, we get

x=tan^{-1}(3/4)

x≈36.87 (rounded to the nearest hundredth)

Now, let's solve for y, the hypotenuse!

Both the sine and cosine functions work, so I'm just going to pick one.

sine(36.87)=3/y

y*sin(36.87)=3

y=3/sin(36.87)

y=5

Side note: Although I rounded the angle measure, when calculating the y value, on my calculator, I did not round the value. Don't round until the end on your calculator, but it's okay to round on your paper.

PS. I used degrees for the angle measures, not radians, so if you want to retry these problems, make sure your calculator is calculating degrees, not radians, or else you might get some funky answers.

Which describes the reflection of the figure?
olga nikolaevna [1]

Answer:

An object and its reflection have the same shape and size, but the figures face in opposite directions. The objects appear as if they are mirror reflections, with right and left reversed. A reflection can be seen, for example, in water, a mirror, or in a shiny surface.
