Answer:

x = sqrt(17)

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2

Let the unknown side be x

8^2 + x^2 = 9^2

64 + x^2 = 81

Subtract 64 from each side

x^2 = 81-64

x^2 =17

Taking the square root of each side

x = sqrt(17)

Answer:

x = √17

Step-by-step explanation:

Your question have a right triangle.

So, we could use the Pythagorean Theorem.

Pythagorean Theorem is a² + b² = c².

So, 8² + n² = 9².

8² is 64, and 9² is 81.

So, 'n' is 81 - 64.

Let's see... 81 - 64 is 17.

So, It is √17.

Because when you use the Pythagorean Theorem, it is 8² + (√17)² = 9².

Otherwise, 64 +  (√17)² = 81.

And, √17 is 4.12 when rounding to a hundredth.

Hope it helps!

The measure of an angle is 2°. What is the measure of its supplementary angle?

Answers

Answer:

178

Step-by-step explanation:

Please help! I usally get these right but I'm completelly stumped! ( Please explain in detail )

Answers

Answer:

A.   x = 5

Step-by-step explanation:

2 + 8x = 11x - 13   -------- subtract 2 from both sides

2 + 8x - 2 = 11x - 13 - 2

8x = 11x - 15         -------- subtract 11x from both sides

8x - 11x = 11x - 15 - 11x

-3x = -15

x = -15 / -3

Find the ratio in which y-axis divides the line segment joining the points A(5, -6), and B (-1, -4). Also find the coordinates of the point of division.

Answers

Answer:

Something like this

Step-by-step explanation:

distance √(-1 - 5)² + (-6 - -4)² = √36 + 4 = √40 = 6.32

slope = 2/-6 = -1/3

distance (-1,-4) to (0, -4.63)

√(-1 - 0)² + (-4 - -4.63...)² = √1.4 = 1.18

6.32 - 1.18 = 5.14

1.18 : 5.14

Answer:

ratio 5:1

coordinates (0,-13/3)

Step-by-step explanation:

let any point on y-axis  (0,y)  divides the join of A(5,-6) and B(-1,-4) in the ratio k:1

[tex]0=\frac{-1(k)+1(5)}{k+1} \\or~0=-k+5\\or~ k=5\\\therefore ~y-axis~ divides ~A,B~in~the~ratio~5:1\\y=\frac{5(-4)+1(-6)}{5+1} =\frac{-26}{6} =-\frac{13}{3}[/tex]

so coordinates of point of intersection are (0,-13/3)

Answer:

D. 22.5

Step-by-step explanation:

By the property of intersecting tangent and secant outside of the circle, we have:

x° = 1/2[(4x+5)° - 50°]

2x° = [(4x+5)° - 50°]

2x° = (4x-45)°

2x = 4x - 45

45 = 4x - 2x

45 = 2x

x = 45/2

x = 22.5

Serena makes $9 per hour cutting lawns. Each day, she earns about $15 in tips.

Answers

Answer:

The answer is  15 h + 9 greater-than-or-equal-to 110

Step-by-step explanation:

For us to represent the inequality of the equation for the number of hours worked. let us identify the parameter involved the.

daily earnings in tips = $15

normal daily pay=>$110

number of hours worked is represented by h

Hence the equation for the pay is

15 h + 9 >=110

Note: we use the >= symbol in the equation because $110 is the minimum amount Serena will always receive any amount she must receive must always be greater than $110

What are the coordinates of the point 3/4 of the way for A to B

Answers

Answer:

Coordinates of the point P are [tex](-\frac{29}{7},-1)[/tex]

Step-by-step explanation:

If a point P(x, y) divides the line AB into the ratio of m : n, coordinates of this point will be,

x = [tex]\frac{mx_2+nx_1}{m+n}[/tex]

y = [tex]\frac{my_2+ny_1}{m+n}[/tex]

In the given question m : n = 3 : 4

And the coordinates of A and B are (-5, -4) and (-3, 3) respectively.

x = [tex]\frac{3(-3)+4(-5)}{3+4}[/tex]

x = -[tex]\frac{29}{7}[/tex]

y = [tex]\frac{3(3)+4(-4)}{3+4}[/tex]

y = -1

Therefore, coordinates of the given point P are [tex](\frac{29}{7},-1)[/tex].

A scientist measures the change in the temperature of a chemical solution at the start of the experiment, the solution is at a temperature of -14.96 C the temperature increases 2.9C each hour what is the temperature of the solution after 3 hours rounded to the nearest whole degree?

Answers

Answer:

The temperature of the solution after 3 hours rounded to the nearest whole degree is -6 C

Step-by-step explanation:

From the question, the temperature of the chemical solution at the start of the experiment is -14.96 C.

Now, if the temperature increases by 2.9 C each hour,

Then, after 3 hours, the temperature of the chemical solution would have increased by

2.9 C/h × 3 h

8.7 C

Hence, the temperature of the chemical solution would have increased by 8.7 C after 3 hours.

The temperature of the chemical solution after 3 hours will be

-14.96 C + 8.7 C

= -6.26 C

≅ -6 C (to the nearest whole degree)

Write the following equation in slope-intercept form.
3x - 2y=5

Answers

Answer:

y = 3/2x -5/2

Step-by-step explanation:

Slope intercept form is

y = mx+b  where m is the slope and b is the y intercept

3x- 2y = 5

Solve for y

Subtract 3x from each side

3x -3x- 2y =-3x+ 5

-2y = -3x+5

Divide by -2

-2y/-2 = -3x/-2 +5/-2

y = 3/2x -5/2

Carlos Gonzales, the left fielder for the Colorado Rockies, a major league baseball team, played in 135 games in 2012 and hit 22 home runs. If he plays a total of 1075 games in his career, approximately how many home runs he will hit.

Answers

Answer: About 175 homeruns

Step-by-step explanation:

For every 135 games played, he hit 22 home runs, which makes an average of 1 home run every 6.136 games. Take that number and divide 1075 by it.

1075 / 6.136 = about 175.

Carlos Gonzales hits 175 runs in his total of 1075 games in his career.

What is ratio?

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Number of games played by Carlos Gonzales = 135.

And runs hit by Carlos Gonzales = 22 runs.

To find the runs hit by Carlos Gonzales in 1075 games,

Use ratio property,

In 135 games = 22 runs hit,

in 1 game = 22 / 135 runs hit,

In 1075 games = (22/135)x1075 = 175.18 = 175 (approx)

The runs hit by Carlos Gonzales in 1075 games is 175.
