Answer:

8.77 or 8.80

Step-by-step explanation:

sin (20) = 3/x

x (sin)20)) = 3

divide by sin(20)

x= 8.77 or 8.8

Answer:

The answer would be 5.5

Step-by-step explanation:

To prove it, 10 x 2.5 x 5.5 would equal 137.5

Answer:

-5

Step-by-step explanation:

If you add 5 to -5 it will be 0 due to the - in -5. This is because negative numbers are below 0.

Answer:

y = x + 1

Step-by-step explanation:

Answer:

Answer is yes

Step-by-step explanation:

yess it's yes

Answer:

Yes

Step-by-step explanation:

The ratio between x and y is equivalent, one variable is always a constant value times the other.

Answer:

Let the scores on the first two test be x

Let score for third test be 14 exceeds second( or first) = x + 14

Total = 233

x + x + (x + 14) = 233

3x + 14 = 233

3x = 219

x = 73

Score of the third test = x + 14 = 73 + 14 = 87

Therefore, the scores are 73, 73, 87

Answer:

B,48.2

Step-by-step explanation:

To solve this we need to use SOH, CAH, TOA

we have the adjacent and hypotonouse so it's easiest to use CAH

let theta (angle) = x

cos(x)=4/6

to cancel the cos mulitply both sides by cos^-1 (2nd --> cos)

x=48.1896851

which rounds to 48.2

Answer:

x = 11 explanation : " $3 subtracted from the cost of the book just number 8! " As an equation this would be : x - 3 = 8 SOLVE x - 3 = 8   + 3  + 3 x = 11 KEY x = cost of book 

hope it helps

Answer:

the answer is −4x+10y−6z

Answer:

The interval is [4,7]

Step-by-step explanation:

The rate of change is given by

f(x2) - f(x1)

-------------------

x2 -x1

We want the rate of change to be 56

f(x2) - f(x1)

-------------------  = 56

x2 -x1

We also know that the x2 is 7  so f(x2) = 192

192 - f(x1)

-------------------  = 56

7 -x1

192 - f(x1) = 56( 7 -x1)

192 - f(x1) = 392 -56x1

Now we need to pick points from the table and see where it is true

(6,96)

192 - 96 = 392 -56*6

96=56  False

( 5,28)

192 - 28 = 392 -56*5

164=112  False

(4,24)

192 - 24 = 392 -56*4

168=168  True

The interval is [4,7]

Answer:

[tex]P(X \geq 13) = 0.021[/tex]

Step-by-step explanation:

From the question we are told that:

Probability of curing patients P(x)=0.65

Sample size n=14

Generally the Binomial equation is mathematically given by

[tex]P(X) =\frac{(n!)}{X!(n-X)!))} *p^X*(1-p)^(n-X)[/tex]

Generally the equation for Equation for at least 12 cured is mathematically given by

[tex]P(X \geq 13) = P(X = 13)+P(X = 14)[/tex]

For [tex]P(X = 13)[/tex]

[tex]P(X = 13) = (14!/(13!(14-13)!))*0.65^13*(1-0.65)^(14-13) \\\\P(X = 13)= 0.018116[/tex]

For [tex]P(X = 14)[/tex]

[tex]P(X = 14) = (14!/(14!(14-14)!))*0.65^14*(1-0.65)^(14-14) \\\\P(X = 14)= 0.00240318[/tex]

Therefore

[tex]P(X \geq 13) =P(X = 13)+P(X = 14)[/tex]

[tex]P(X \geq 13) = 0.018116+0.00240318[/tex]

[tex]P(X \geq 13) = 0.02051918[/tex]

[tex]P(X \geq 13) = 0.021[/tex]

Answer:

Step-by-step explanation:

let radius of shere A=R

radius of sphere B=r

[tex]\frac{volume~of~sphere ~A}{volume~of~sphere~B} =\frac{\frac{4}{3} \pi R^3}{\frac{4}{3} r^3} =\frac{125}{64} \\(\frac{R}{r} )^3=(\frac{5}{4} )^3\\\frac{R}{r} =\frac{5}{4}[/tex]

Answer:

[tex] {3y}^{3} - 12y \\ = 3y( {y}^{2} - 4) \\ = 3y( {y}^{2} - {2}^{2} ) \\ = 3y(y - 2)(y + 2) \\ = 3y(y + 2)(y - 2)[/tex]

a^2-b^2=(a+b)(a-b)

a=y b=2

3y(y+2)(y-2)

Answer:

75ft^2

Step-by-step explanation:

A = pi*r^2

The circle already gives the diameter and the diameter is two times the radius, so if you were to divide the diameter by two, you would get 5.

Knowing the radius is 5 and seeing how they replaced pi with 3 we can set up the equation.

3*(5)^2 = A

Simplify

3*25

Multiply

Area=75ft^2

Answer:

A

Step-by-step explanation:

Just A!

Answer:

Step-by-step explanation:

Never capitalize the seasons

Answer:

Linear

Step-by-step explanation:

As x increases by 1, f(x) decreases at a constant rate of -5.

Since the rate is constant, the function must be linear.

Answer:

5.14 ft

Step-by-step explanation:

The perimeter of a circle is diameter X 3.14. since its half a circle, take the radius and multiply by 3.14. Since the radius is 1, the answer is pi itself. Then add 2 feet for the flat side of the semi-circle

Answer:

Volume, V = 75.41 cubic inches.

Step-by-step explanation:

Given the following data;

Radius, r = 3 inches

Height = 8

To find the volume of the right circular cylinder;

Mathematically, the volume of a right circular cylinder is given by the formula;

V = πr²h

Where;

Substituting into the formula, we have;

Volume, V = 3.142 * 3 * 8

Volume, V = 3.142 * 24

Volume, V = 75.41 cubic inches.
