What is the answer to this math problem

Answer:

56.9°

Step-by-step explanation:

Assuming you mean a and b as the legs of a right triangle and θ as the bigger angle in a right triangle, we can work out easily that

cos θ = 6/11

so θ ≈ 56.9°(to 1 d.p.)

Answer:

$15.70

Step-by-step explanation:

The formula for a circle's area is πr^2 and so the radius is 10/2 or 5. 3.14*5^2 is 78.54. Multiply this by $0.20 to get the total cost of the pizza. The total cost is $15.70.

Answer:

11/5 = 11 ÷ 5

Step-by-step explanation:

11/5 is a fraction, and every fraction is just a division problem.

Answer:

11/5=11÷5.

You just take the numbers from the fraction and put them into a division equation.

I don't know but 4 could be it

Step-by-step explanation:

Answer: b = 9

Step-by-step explanation:

Given

12 + 5/3b + 11 - 18 = 20

Combine like terms

(12 + 11 - 18) + 5/3b = 20

5 + 5/3b = 20

Subtract 5 on both sides

5 + 5/3b - 5 = 20 - 5

5/3b = 15

Divide 5/3 on both sides

5/3b / (5/3) = 15 / (5/3)

b = 9

Answer:

the inequality will be X > 73

Step-by-step explanation:

Answer:

c = -4    d = 6

Step-by-step explanation:

8 - 2d = c     4c + 3d = 2

                    4(8 - 2d) + 3d = 2

                     32 - 8d + 3d = 2

                     32 - 5d = 2

                          -5d = -30

                              d = 6

8 - 2(6) = c

8 - 12 = -4 = c

Answer:

x = √3

Step-by-step explanation:

Looking at the given triangle,

x is the adjacent side while 2 represents the hypotenuse side.

Now, from trigonometric ratios, we know that;

Adjacent/hypotenuse = cos θ

The angle here will be 30°

Thus;

x/2 = cos 30°

We are told to find x in simplest radical form with a rational denominator.

Thus means we will use the surf value of the angle.

cos 30° in surd form = (√3)/2

Thus;

x/2 = (√3)/2

x = 2 × (√3)/2

x = (√3)/1

x = √3

Answer:

[tex]123.19890025 kg^2[/tex]

Step-by-step explanation:

We are given that

Standard deviation, s=11.0995 kg

Sample size, n=10

We have to find the variance of their weights.

We know that

Variance=[tex](standard\;deviation)^2[/tex]

Using the formula

The variance of their​ weights

=[tex](11.0995)^2[/tex]

=[tex]123.19890025 kg^2[/tex]

Hence, the variance of their​ weights=[tex]123.19890025 kg^2[/tex]

Answer:

First, converting R percent to r a decimal

Solving our equation:

The initial deposit amount is $4,250.00.

Given that,

Based on the above information, the calculation is as follows:

We know that

[tex]SI =P\times R\times T\\\\SI = P\times 2.7\% \times 22\\\\SI = 0.594P[/tex]

Now

Investment worth = P  + SI

= P + 0.594P

= 1.594P  

So,  

1.594P  = 6774.50

P  = $4,250  

Therefore we can conclude that the initial deposit amount is $4,250.00.

Answer:

[tex]G' = (3,1)[/tex]

[tex]H' = (-4,0)[/tex]

[tex]I' = (-2,-3)[/tex]

Step-by-step explanation:

Given

See attachment for points G, H and E

Rotation: 90 degrees clock-wise

Required

Determine the coordinates after rotation

From the attachment:

[tex]G = (-1,3)[/tex]

[tex]H = (0,-4)[/tex]

[tex]I = (3,-2)[/tex]

When a point (x,y) is rotated 90 degrees clockwise, the new point is: (y,-x)

So, we have:

[tex]G = (-1,3)[/tex]

[tex]G' = (3,1)[/tex]

[tex]H = (0,-4)[/tex]

[tex]H' = (-4,0)[/tex]

[tex]I = (3,-2)[/tex]

[tex]I' = (-2,-3)[/tex]

Making the equation false

Answer:

James = £60, Ryan = £40 and Jill = £20

Step-by-step explanation:

James - 3, Ryan - 2 and Jill - 1

3 + 2 + 1 = 6

£120 / 6 = 20

Times 20 by each of the three numbers (3, 2 and 1)

3 x 20 = £60 (James)

2 x 20 = £40 (Ryan)

1 x 20 = £20 (Jill)

Answer:

James gets £60

Ryan gets £40

Jill gets £20

Step-by-step explanation:

Add up the ratio which would be 6 then divide it by the original sum which is £120 so the answer would be 20. You would then multiply 20 by each number so 20x3= 60. 20x2= 40. 20x1=20

All these should add up to your original sum and if they do you know you've done it right!
