Answer:

a year is 12 months so there would be 6 months in half a year

Answer:

6

Step-by-step explanation:

there are 12 months in a whole year so just divide that by 2 and you get 6!

We can name the sides of a right triangle by finding their location given one of the angles.

The sine, cosine, and tangent ratios are the three basic trigonometric ratios:

The given angle in this case ([tex]\theta[/tex]) is the angle that measures 15°.

We're also given the side adjacent to it (that is not the hypotenuse), which measures 300 units.

And finally, we're asked to solve for the side opposite the given angle.

The ratio that involves solving using the opposite and the adjacent sides is the tangent ratio. Plug in all the given values:

[tex]\tan\theta =\dfrac{opposite}{adjacent}\\\\\tan(15^\circ)=\dfrac{x}{300}[/tex]

Isolate x by multiplying both sides by 300:

[tex]300\tan(15^\circ)=x\\\\300\tan(15^\circ)=80.4[/tex]

Therefore, x = 80.4 when rounded to the nearest tenth.

x = 80.4

Answer:

Step-by-step explanation:

using the identity

tan²x = sec²x - 1

consider the left side

(tanx + secx)² ← expand using FOIL

= tan²x + 2tanxsecx + sec²x

= sec²x - 1 + 2tanxsecx + sec²x ← collect like terms

= 2sec²x + 2tanxsecx - 1

We will see that the value of a is 12.

We have a Fibonacci sequence, and the first four terms are:

a, 2a, 3a, 5a.

Because it is a Fibonacci sequence, the next term should be the sum of the two previous ones.

3a + 5a = 8a

Then the sum of the first 5 terms is:

(a + 2a + 3a + 5a + 8a) = 228

We can solve this for a.

(1 + 2 + 3 + 5 + 8)*a = 228

19*a = 228

a = 228/19 = 12

So we conclude that the value of a is 12.

Answer:

160 square units

Step-by-step explanation:

First, lets focus on the triangles.

To find the area of a right triangle, we need to multiply the length by the width, and divide by 2.

(5 * 8) / 2 = 20

(And since there is two triangles, the area of the two is 40.)

To find the area of a rectangle, we need to multiply the length by the width.

15 * 8 = 120

Now we add all the areas together.

120 + 20 + 20 = 160

Is the answer is 160 square units.

Answer:

20 pieces

Each roll has 36 inches of ribbon. This means that 5 rolls have 180 inches of ribbon (5 x 36 = 180).

You can then divide the 180 by 9 to find out how many 9 inch pieces the dressmaker can cut from 5 rolls of ribbon.

Equation representation:

36 inches x 5 rolls = 180 inches in total
(one roll)

180 inches ÷ 9 = 20 peices

In conclusion, the dressmaker can cut 20, 9-inch pieces from 5 rolls of ribbon.

Since the shape is a parallelogram, there are 2 pairs of opposite but equal sides --> "6a+21" and "20a+7"                   "11a" and "4a+7"

The easier pair is

11a = 4a+7              Subject 4a from both sides

7a = 7                     Divide 7 from both sides

a = 1

A = 1    

Answer:

You would do this problem like a normal varible problem. x=10

Step-by-step explanation:

Since 9x is a right angle the inside would also be 9x

9x+4x+10+40=180

180 because that is how much a triangle equals

combine like terms

13x+50=180

subtract 50 from both sides

13x=130

divide by 13

x=10

I'm not too shmert so I will guess, ok?

Answer: I think it would be Decrease but I may not be correct

The correct answer is OA. It is the graph of f(x) translated 11 units to the right.

The transformation g(x) = f(x - 11) represents a horizontal translation of the graph of f(x) = x.

When we substitute x - 11 into the function f(x), it shifts the entire graph 11 units to the right.

This is because for every value of x in f(x), we are now evaluating f(x - 11), which means the x-values are shifted to the right by 11 units.

Therefore, the correct statement is that g(x) is the graph of f(x) translated 11 units to the right.

Answer:

Mrs. Foster's class had the most students in class that Friday

Step-by-step explanation:

Mr Lopez - 92.5%

Mrs Foster - 19/20

Mr Kelly - 0.9

Let's say that there were 40 students in class

92.5% of 40 would be 37

So

Mr Lopez's Class had 37 students.

19/20 of 40 would be 38

So

Mrs Foster's Class had 38 students

0.9 of 40 would be 36

So

Ms Kelly's class had 36 students

Therefore, from looking at this, the answer would be Mrs Foster's Class
