Answer:

D. √2

Step-by-step explanation:

Solve for x by applying trigonometric ratio.

Reference angle = 45°

Hypotenuse = 2

Adjacent side = s

Thus:

Cos (45) = adj/hyp

Cos (45) = s/2

2×Cos(45) = s

2 × √2/2 = s (cos (45) = √2/2)

√2 = s

s = √2

Answer:

Unknown

Step-by-step explanation:

Since you have 35 C, you will have 35 G. Without knowing the number of thymine, the number of adenine is unknown .

That is all the information you can get from this. Just because there are 35 C and G, there doesn't have to be an equal number of A and T

Answer:

C.

Step-by-step explanation:

Hi there!

To find the answer to this, plug the number values in for n and then solve.

For the answer to be correct, the sum has to be less than 26.

Answers B and D both have numbers that would be equal to 26, so they aren’t right.

Answer A has numbers that would go over 26.

Every number in C can be added to 15 and the sum would be less than 26.

I hope this helps!

Answer:

Step-by-step explanation:

The area of each rectangle is Length x width

Therefore Area of rectagle is 8cm x 10 cm=

A= 80 cm 2

There are three rectangles with the same measure so multiply the area by 3

80cm squared x 3= 240 cm 2

Now find the are of the triangle:

A- 1/2 x base x height

Base = 8cm

Height = 6.9 cm

A= (1/2) (8cm) (6.9cm)

A= (1/2) (55.2 cm squared)

A= 27.6 cm squared

Since there are two triangle faces with the same dimensions take the area and multiply it by 2

27.6 cm squared times 2 = 55/2 cm squared

Now add up the area of the rectangles and the area of the triangles.

Rectangles= 240 cm squared

Triangles 55.2 cm squared

240cm sq + 55.2 cm sq.= 295.2 cm squared

I'm pretty sure it would be

Answer:

42in

Step-by-step explanation:

First divide up the shape.

The bottom will cut off to form a 6x3 rectangle which will have an area of 18in.  Next is the top portion which is a trapezoid. You can figure out the area two ways. You can divide it further into two triangles and a rectangle. Or you can use the trapezoid formula. In this case I feel like dividing it. So since the top is 2 inches the bases of the two side triangles must be 2 due to the bottom base of the whole shape being 6. (1/2*2*6)*2 = 12in. Lastly the center rectangle is 2*6 (got 6 from 9-3) which is also 12. So the top half added together 12+12 equals 24in. When adding both top and bottom portions (18+24) you get 42in.

Answer: A= 2.5

              B= 12.9

              C= 12

              D= 3 (the 3 is a whole number not added to the fraction.)

              E= 4

Answer:

  88.2

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relevant relation ...

  Tan = Opposite/Adjacent

  tan(10°) = x/500

  x = 500·tan(10°)

  x  ≈ 88.2 . . . . units

_____

If you move the "500" dimension to the top of the figure, you see it is adjacent to the given angle, and the value x is opposite.

Answer:

17x + 22

Step-by-step explanation:

They are supplementary angles...

Which means...

Angle ADE = (4x+15) + (13x+7)

= 17x + 22

So...

Angle ADE = 17x + 22

Answer:

  5 miles

Step-by-step explanation:

Time/speed/distance problems can be worked a number of ways. Here, we want to know the distance walked. We know the total time and the total distance and the two different speeds. So, we can use a variable to represent the value we want to know: w = distance walked (in miles).

The total time is 9:00 -6:50 = 2:10 = 2 1/6 hours = 13/6 hours.

The total time is the sum of times for the two parts of the trip: walking and riding.

  walking time = walking distance/walking speed

  = w/3

  riding time = riding distance/riding speed

  = (20-w)/30

The total time is that given above:

  w/3 +(20-w)/30 = 13/6

  10w +(20 -w) = 65 . . . . . . . . multiply by 30

  9w = 45 . . . . . . . . . . . . subtract 20, collect terms

  w = 5 . . . . . . . . . . . divide by 9

Answer:

There were 56 different choices for the five locations to apply the new ointment.

Step-by-step explanation:

The order of the locations in which the new ointment was applied is not important. So we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

How many different choices were there for the five locations to apply the new ointment

Five locations from a set of 8. So

[tex]C_{8,5} = \frac{8!}{5!(8-5)!} = 56[/tex]

There were 56 different choices for the five locations to apply the new ointment.

[tex]\frac{26}{100}[/tex]×[tex]\frac{5000}{1}[/tex] =1300

Answer:

Step-by-step explanation:

(a)

well since they can lay 7 miles of track every day, the formula i make for the amount of track there is left to lay is:

L=196-Ld

where l is the length of track remaining, L is the length of track they can lay in one day and d is the number of days.

so we replace L for 7 and d for 17 and we get:

L=196-7x17

which works out to be 77 miles of track remaining to lay.

(b)

well since we want them to have 0 length of track remaining, and they can lay 7 miles of track a day, we can work out d. let's give the formula a bash to get:

d=196-l/L

we then replace l with 0 and L with 7 and get:

d=196/7

which works out to be 28. so it will take 28 days or 4 weeks for the railroad crew to lay 196 miles of track.

Step-by-step explanation:

step 1. 6x - 30 = 2(x + 33)

step 2. 6x - 30 = 2x + 66

step 3. 4x = 96

step 4. x = 24.

step 5. mNMO = x + 33 = 24 + 33 = 57°.

Answer:

 h(x) =  -x² + 11 x + 2

Step-by-step explanation:

Explanation:-

Given that the functions are  

                                            f(x) = 2 x² - 5x -3

                                            g(x) = x² + 6x -1

               h(x)  = g(x) - f(x)

                      = x² + 6x -1 - (2 x² - 5x -3)

                     = - x² + 6 x +5x -1+3

                    = -x² + 11 x + 2

            h(x) =  -x² + 11 x + 2

Final answer:-

h(x) =  -x² + 11 x + 2
