Answer:

  see attached

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships between sides and trig functions. The relevant relations here are ...

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

In your diagram, leg 'a' is opposite angle α and adjacent to angle β. Similarly, leg 'b' is opposite angle β and adjacent to angle α. The hypotenuse is 'c' in all cases.

So, filling the table is a matter of identifying adjacent and opposite legs. You will notice that the sine of α is the cosine of β and vice versa.

Answer: 3

Step-by-step explanation:

f(x)= -x + 4

Therefore f(-1)= -(-1)+4= 1+4= 5

h(x)= (3/2)x - 1

Therefore h(2)= (3/2)(2) -1= 3-1= 2

f(-1) - h(2)= 5 - 2= 3

Answer:

Volume = 125 mm^3

Step-by-step explanation:

Here, we want to get the volume of the cube

What we have to do here is to substitute the value of the area

We have this as

:

V = 25^(3/2)

V = (√25)^3

V = 5 * 5 * 5 = 125 mm^3

Answer: 40 pages in total

Step-by-step explanation:

Ms. Vega has read 20% of the book and this translates to 8 pages of the book.

20% = 8 pages

Assume the total number of pages is x:

20% * x = 8

0.2x = 8

x = 8 / 0.2

x = 40 pages in total

Answer:

40 pages in book

Step-by-step explanation:

8 pages read

8/40 = .20

Step-by-step explanation:

3/7 is greater than 1/4

Answer:

solve it yourself

Step-by-step explanation:

length of ist part= 30 cm

breadth of ist part = 21 cm

area of ist part = 630 cm

diameter of 2nd part= 21 cm

area of 2nd part = ¼dπ

π= 22/7

= ¼× 21 ×22/7

=3×10.5

= 31.5cm²

total area = ist part +2nd part + 3rd part

Answer:

M = (4,7)

Step-by-step explanation:

If points are (x₁,y₁) and (x₂,y₂), then the midpoints are given by :

[tex]M=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]

We have,

x₁ = -2, y₁ = 8, x₂ = 10 and y₂ = 6

So,

[tex]M=(\dfrac{-2+10}{2},\dfrac{8+6}{2})\\\\=(\dfrac{8}{2},\dfrac{14}{2})\\\\=(4,7)[/tex]

So, the midpoints of the given points are (4,7).

Answer:

F. $6,840

39,840-33,000 = $6,840

Answer:

Sum of their present ages  = 20 years

Step-by-step explanation:

Present age :

   Neha's age = x years

Reemas' age = x - 4

After 5 years:

       Neha's age = (x +5) years

       Reemas' age = (x - 4 + 5 ) = x + 1

Sum of the ages of Reema and Neha will be 30

Therefore,    

x + 5  + x + 1 = 30

x + x + 5 + 1 = 30

   2x +  6    = 30

            2x = 30 - 6

           2x = 24

             x = 24/2

            x = 12

Neha's age = 12 years

Reema's age = 12 - 4 = 8 years

Sum of their present ages = 12 + 8 = 20 years

Answer:

y=Q+3D

Step-by-step explanation:

the total amount is y=, than A would be quarters. and you add 3 because there's always 3 more dimes than quarters than add D for dimes.

The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

You have $3.10 in dimes and quarters. You have 3 more dimes than quarters.

Let 'x' be the number of dimes and 'y' be the number of quarters. Then the equation is given as,

0.10x + 0.25y = 3.10      ...1

x = y + 3                        ...2

From equations 1 and 2, then we have

0.10(y + 3) + 0.25y = 3.10

0.10y + 0.30 + 0.25y = 3.10

0.35y = 2.8

y = 8

Then the value of 'x' is given as,

x = 8 + 3

x = 11

The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.

Step-by-step explanation:

Answer: [tex]V = 24,416.64m^{3}[/tex]

Step-by-step explanation:

Solve for v  by simplifying both sides of the equation, then isolating the variable.

Formula: [tex]v = \frac{4}{3} \pi r^{3}[/tex]

Plugin the variable: [tex]v = \frac{3}{4}\pi (18^{3})[/tex]

Solve:

[tex]v = \frac{4}{3} 3.14 (5,832)[/tex]

[tex]v = 4.18666666(5,832)[/tex]

[tex]V = 24,416.64m^{3}[/tex]

Answer: 3.9ft²

Step-by-step explanation:

Find the area of the rectangle first:

= Length * Width

= 2 * 1.5

= 3 ft²

Find the area of the semi-circle by finding the area of a circle and dividing it by 2:

= πr²

= 3.14 * 1.5/2 * 1.5/2

= 1.76625‬ft²

Divide by 2:

= 1.76625‬/ 2

= 0.88 ft²

Add the area of the rectangle to the semi-circle:

= 3 + 0.88

= 3.9ft²

Answer:

9.43 ft

Step-by-step explanation:

First, we need to find the area of the entire circle(shaded & unshaded), which is 12.57, with a radius of 2 ft. Next, we find the area of the white area, and NOT the shaded area, which is 3.14, with a radius of 1 ft. Now, we need to subtract the white area(3.14) from the total area(12.57), which is 9.43.

Hope this helps!
