Answer:

9. 6.6

10. 6

11. 8.9

Step-by-step explanation:

Pythagorean theorem states that a^2 + b^2 = c^2 where a and b are legs, and c is the hypotenuse (the longest side of the triangle).

For the first one, you're given the leg (3.1 in) and the eg (5.8 in), so you can substitute those into the equation:

a^2 + b^2 = c^2

(3.1)^2 + (5.8)^2 = c^2

Then simplify

9.61 + 33.64 = c^2

43.25 = c^2

To isolate c, take the square root of both sides.

The square root of 43.25 is 6.57647322, but they want you to round it to the nearest tenth, so round it to 6.6

For the second one, you're given one leg length and the hypotenuse.

8^2 + b^2 = 10^2

64 + b^2 = 100

To solve for b, subtract 64 from both sides

b^2 = 36

and take the square root of both sides

b = 6

For the last one, you're given a leg length and the hypotenuse

a^2 + 4.3^2 = 9.9^2

a^2 + 18.49 = 98.01

to isolate a, subtract 18.49 from both sides

a^2 = 79.52

then take the square root of both sides

a = 8.91739872 which rounds to 8.9

Answer:

AB = AC×cos theta= cos theta

Given:

The equation is:

[tex]\dfrac{5}{7}y=6[/tex]

To find:

The solution of the given equation by using the reciprocals.

Solution:

We have,

[tex]\dfrac{5}{7}y=6[/tex]

We need to multiply both sides by the reciprocal of [tex]\dfrac{5}{7}[/tex] to isolate the variable x.

The reciprocal of [tex]\dfrac{5}{7}[/tex] is [tex]\dfrac{7}{5}[/tex]. So, multiplying both sides by [tex]\dfrac{7}{5}[/tex], we get

[tex]\dfrac{5}{7}y\times \dfrac{7}{5}=6\times \dfrac{7}{5}[/tex]

[tex]y=\dfrac{42}{5}[/tex]

[tex]y=8.4[/tex]

Therefore, the value of y is 8.4.

Answer:

If the dice are fair and 6 sided then you can roll a 4 in three ways

2    2

1     3

3    1

The total number of ways you can throw two 6 sided dice is 6 * 6 or 36

So P(4) = 3/36 = 1/12

Answer:

[tex]y=-\frac{5}{3} x+5[/tex]

Step-by-step explanation:

Points on the graph: (0, 5) and (3, 0)

Slope:

m=(y2-y1)/(x2-x1)

m=(0-5)/(3-0)

m= (-5)/3

m= -5/3

Slope-intercept:

y - y1 = m(x - x1)

y - 5 = -5/3(x - 0)

y - 5 = -5/3x

y = -5/3x + 5

Answer:

[tex]Y = 20.239[/tex]

Step-by-step explanation:

Given

[tex]Y = 9.1411 + 0.4775X[/tex]

Required

The predicted value of [tex]Y[/tex] when [tex]X = 23.2417[/tex]

To do this, we substitute [tex]X = 23.2417[/tex] in the given equation

So, we have:

[tex]Y = 9.1411 + 0.4775X[/tex]

[tex]Y = 9.1411 + 0.4775 * 23.2417[/tex]

[tex]Y = 9.1411 + 11.0979[/tex]

[tex]Y = 20.239[/tex]

Answer:

[tex]\implies \sec 3 30^o = \dfrac{2}{\sqrt3}=\dfrac{2\sqrt{3}}{3}[/tex]

Step-by-step explanation:

Given :-

And we need to find out its value . Firstly we know that 330° lies in 4th quadrant . And In fourth quadrant , cosine and secant are positive . Therefore , the result will be positive. Now we know that ,

[tex]\implies \sec (360^o-\theta)= \sec\theta [/tex]

Using this ,

[tex]\implies \sec (330^o) \\\\\rm\implies sec(360^o-30^o) \\\\\rm\implies \sec 30^o [/tex]

And the value of sec 30° is ,

[tex]\implies \sec 30^o = \dfrac{2}{\sqrt3}[/tex]

And by question we need to write it with a rational denominator .So on rationalising the denominator , we have ,

[tex]\implies \sec 30^o = \dfrac{2}{\sqrt3}=\boxed{\red{\dfrac{2\sqrt3}{3}}}[/tex]

Hence the required answer is 2√3/3.

This is the way I did it, I don't know if your going to do it this way so use it as an refrence!

10 - 4 = 6

30 ÷ 6 = 5

5 x 10 = 50

Answer:

$50.00

Step-by-step explanation:

This is because 30 is 60% of 50. (100% - 40% = 60%)

You can verify this answer by calculated 40% of 50, which is 30.

Answer:

So you are going to multiply what is in the parentheses by two it will become 6x + 4.This will be for the second statement box. And the next will be 6x=18 and that will be the subtraction property or equality. For the last it would be x=3 and that would be the division property of equality.
