Please help me solve this :((

Answer:

35/37

Step-by-step explanation:

In this question, we are to calculate the ratio that represents the cosine of angle O

Firstly, please check the attachment for the diagram of the triangle.

Mathematically, the trigonometric term Cos means the ratio of the length of the adjacent to that of the hypotenuse

The hypotenuse is the longest length which is 37 which represents the length ON

The side adjacent to angle O is the side OP which is 35

Thus, the ratio representing the cosine of angle O is 35/37

Answer:

-1 because if you look you have multiple it

Answer:

Slope = -5/4

y-intercept = 7

Step-by-step explanation:

The equation is y = mx + b.

m is the slope, while b is the y-intercept.

Because -5/4 is where m would be in the equation, it is the slope.

7 is where b would be in the equation, so it is the y-intercept.

Answer:

It is correct actually.

Step-by-step explanation:

141 + 39 = 180

Yeah, that's correct

Explanation: Supplementary angles add to 180 degrees. If angle R is 39 degrees then angle S has to be 141 degrees because 39 + 141 = 180.

Answer:

1.2 OR 1 1/5

Step-by-step explanation:

-3 x 2 x 2 = -12

-3 x 2 = -6

2 x = 4

-12 / -6 - 4 =

-12 / -10 =

1.2 OR 1 1/5

7x/7 = 14/7

x = 2

Answer:

Step-by-step explanation:

6v + 12b = 504       eq1

2v +  5b = 204        eq2

6v +  15b = 612       eq2  times 3    

0     -3b   = 504 - 612        subtraction of the two bolded eqs

         -3b  =  -108                solve for b

            b  =    36

    Another way to solve the problem

6v + 12b = 504        I would eliminate the v term by multiplying the bottom

2v +  5b = 204        equation by -3 on BOTH sides and then add the two eqs

   2v +  5b  = 204

-3(2v +  5b) = -3(204)

 -6v  -  15b  =  -612

6v  + 12b  =   504

-6v  -  15b  =  -612            add the like terms

(6v + (-6v)) + (12b + (-15b)  =  504 + (-612)

(6v -6v)) + (12b - 15b)  =  504 - 612)

    0       +         -3b     =    - 108            solve for b   divide both sides by -3

                           b   =  -108/-3

                             b =  36                  

use eq   2v +  5b = 204       to solve for v       and knowing b = 36

        2v +  5b = 204      b=36

        2v +  5(36)  = 204                 substract 5 times 36 from both sides

                 2v   =   204 - 180

                    v  =    24 / 2

                    v  =  12

NOW CHECK the values for b and v using the OTHER eq

       6v      +     12b      =    504

       6(12)   +   12(36)    =    504

         72    +     432      =    504

                        504      =    504           IT CHECKS

Answer:

Step-by-step explanation:

The roots (zeros) of the function are (1, 0) and (3, 0). The point (2, 2) is the vertex, the maximum in this case.

The domain of any polynomial function is "all real numbers".

The range is y ≤ 2, not y < 2.

Answer:

6

Step-by-step explanation:

[tex]\sqrt{10^{2} -8^{2} }[/tex] = 6

Answer:

b = 6

Step-by-step explanation:

Pythagorean formula:

a² + b² = c²

Work:

a² + b² = c²

8² + b² = 10²

64 + b² = 100

b² = 100 - 64

b² = 36

[tex]\sqrt{b^2} =\sqrt{36}[/tex]

b = 6

Answer: 25%

Step-by-step explanation:

Given

Initial Cost of share [tex]C.P.=16\$[/tex]

After a month, its selling price is [tex]S.P.=20\$\ \text{per share}[/tex]

The gain percentage is given by

[tex]\Rightarrow \text{Gain }\ \%=\dfrac{\text{S.P.-C.P.}}{\text{C.P.}}\times 100[/tex]

[tex]\Rightarrow \text{Gain}\ \%=\dfrac{20-16}{16}\times 100=25\%[/tex]

Answer:

(-4,1)

Step-by-step explanation:

Hey there!

so the solution of two equations is where the two equations cross over

the two equations cross at (-4,1) therefore that is your answer

Answer:

x=4

or, x = 16/4

x = 4

Answer:

d) y = -1/2 + 3

Step-by-step explanation:

Looking at the graph, we can use y = mx + b to find the equation. m is the slope and for slope, we go 1 unit down and 2 units to the right. b is the y variable and our b would be 3.

y = mx + b

y = -1/2x + 3

Answer:

dogs = 2

cats = 80

Step-by-step explanation:

Here I will assume that cats and dogs are proportional

c = y d, if you substitue, you get

10 = y 4, which rearranged, becomes

y = 10/4 = 2.5

now that we know y, we can work out x and y, the missing dogs and cats

4 = 2.5 d

here, dogs = 2

c = 2.5 * 32

2.5 * 32 = 80

here, cats = 80

Answer: -5x+y=6

Step-by-step explanation:

Given

Points on line [tex](-1,1)\ \text{and}\ (0,6)[/tex]

The standard form of an equation is [tex]ax+by=c[/tex]

Using the two-point form of a line

[tex]\Rightarrow \dfrac{y-1}{x+1}=\dfrac{6-1}{0+1}\\\Rightarrow \dfrac{y-1}{x+1}=\dfrac{5}{1}\\\Rightarrow y-1=5x+5\\\Rightarrow y-5x=6\\\Rightarrow -5x+y=6[/tex]

Answer:

A

Step-by-step explanation:

if x=19, 19x3 =57 and 57+123=180 and straight angle = 180 so A

Answer:

X=19

Step-by-step explanation:

123 and 3x are supplementary/they equal 180 added together.

Let's solve your equation step-by-step.

123+3x=180

Step 1: Simplify both sides of the equation.

3x+123=180

Step 2: Subtract 123 from both sides.

3x+123−123=180−123

3x=57

Step 3: Divide both sides by 3.

3x/3 = 57/3

x=19

Have a splendid day.

Answer:

Arithmetic progression is a series of numbers in which each one varies from the one before it by a constant quantity

Geometric progression is a non-zero number sequence in which each term after the first is found by multiplying the previous term by a fixed, non-zero number known as the common ratio.

Answer:

5.7 pints

Step-by-step explanation:

Total pints of paint used = 9.5 pints

Fraction of blue paint used = 2/5 ; while the rest is white paint

Amount od blue paint used :

2/5 * 9.5 = 3.8 pints

Amount of white paint used :

Total pints - blue pints used

9.5 pints - 3.8 pints

= 5.7 pints of white paint.
