Step-by-step explanation:

Use Pythagorean theorem a^2 + b^2= c^2.

6^2 + x^2 = 10^2 or 36 + x^2 = 100. Solve for x by subtracting 36 from both sides. X^2 = 64, then take the square root of both sides. X =8

Consider U = {x|x is a negative real number}. Which is an empty set? {x|x ∈ U and x has a negative cube root} {x|x ∈ U and x has a negative square root} {x|x ∈ U and x is equal to the product of a positive number and –1} {x|x ∈ U and x is equal to the sum of one negative and one positive number}

Answers

Answer:

{x\ x e U and x has a negative square root} is an empty set.

Step-by-step explanation:

If x e U, x is a negative real number, and they don't have a square root (they don't have even roots). Their square roots are complex numbers, not real ones.

The set that will give an empty set will be {x|x ∈ U and x has a negative square root}

What is a set?

A set is a collection of numbers or objects. They are not necessarily arranged in pattern.

Given the following sets

r U = {x|x is a negative real number}

We are to determine the set that is empty. This means we need the set of numbers that are not real numbers.

The square root of a negative number will give a complex number. Hence the set that will give an empty set will be {x|x ∈ U and x has a negative square root}

The measures of the three angles whose sum is 160 are in the extended ratio 2:5:9. Find the exact angle measures.

Answers

Answer: 20°, 50° and 90°

Step-by-step explanation:

From the question, we are informed that the measures of the three angles whose sum is 160 are in the extended ratio 2:5:9.

The exact angle measures will then be:

= 2/(2+5+9) × 160°

= 2/16 × 160°

= 20°

= 5/(2+5+9) × 160°

= 5/16 × 160°

= 50°

= 9/(2+5+9) × 160°

= 9/16 × 160°

= 90°

x is 66 degrees, you just subtract 24 to 90 and it gives you 66.

A motarcar is running at the rate of 66 km per hour. Each other its wheels makes 500 revolutios per minute. find the radius of the wheel.

Answers

Answer:

simple

Step-by-step explanation:

The radius of the wheel can be solved from its given speed and RPM.

Converting km/h to m/min

speed = 66 km / h = 66000 m / 60 min

speed = 1100 m / min

Converting one revolution to meters

1100 m / min = 500 revolution / min ... (given)

500 revolutions = 1100 m

1 revolution = 2.2 m

Solving for the radius of the wheels in meters

1 revolution = 2.2 m

2 * pi * radius = 2.2 m

radius = 2.2 m / 2 * pi

radius = 1.1 m / pi

radius = 0.3501 m

Answers

A linear function in slope intercept form is

y = mx + c

To find the equation, you need m and c. This can be found by substituting the points you have.

For example, 5 = -1(m) + c and -7 = 2(m) + c

From here, do simultaneous equations

c = m + 5

-7 = 2(m) + m + 5

3m = -7 -5

m = -4

c = m + 5

c = 1

Rewrite the equation: (This is your answer)

To solve this question, we must know the the angle sum property of a triangle. Therefore the value of ∠⁡⁣B is 85° when ∠A = 75° and ∠C=20° in △ABC

What is angle sum property of a triangle?

According to angle sum property of a triangle, the sum of all angles of a triangle is always 180 degree. It can never be more than or less than 180 degree. If two angles of a triangle is given then the third angle can be calculated by subtracting the sum of two angle from 180°

The sum of the three angles in a triangle = 180° , that is

∠ A + ∠ B + ∠ C = 180°

Substituting the given values in the given equation we get

75° + ∠ B + 20° = 180°

∠ B + 95° = 180°

subtracting 95° from both sides we get

∠ B = 85°

Therefore the value of ∠⁡⁣B is 85° when ∠A = 75° and ∠C=20° in △ABC

We want to find the graph of a system of inequalities. We want to select the correct option, but sadly is really hard to interpret the given text, so I will add a graph of the system at the end.

The system is:

y ≤ -3x + 1y ≤ (1/2)*x+ 3

To graph these we first need to graph the two lines:

y =-3x + 1

Is a line with a negative slope that passes through the y-axis at y = 1.

Because here we have y ≤ -3x + 1 we know that y must be equal or smaller than the line, thus we need to shade below the line, and because y can be equal to any value in the line we need to use a solid line.

For the other equation:

y = (1/2)*x+ 3

We have a positive slope and this line intercepts the y-axis at y = 3.

Similar as before, here we have y ≤ (1/2)*x+ 3 so the shaded area will be below the line and the line must be solid.

With this in mind, we can graph the system, and you can see it below:

3/4 = 9/12

6 goes into 12 twice so multiply both the 1 and 6 by two

What is pattern?

A recurring arrangement of numbers, forms, colours, and other elements constitutes a pattern in mathematics. The Pattern can be connected to any kind of occasion or thing. When a group of numbers are arranged in a particular way, the arrangement is referred to as a pattern. Patterns can also occasionally be referred to as a series.

From the given pattern,

Area of the shape in step 1 is 2 square centimeter

Area of the shape in step 2 is 7 square centimeter

Area of the shape in step 3 is 14 square centimeter

Here, the pattern is 2²-2=2

3²-2=7

4²-2=14

so, the general form is (n+1)²-2

Therefore, the area of the shape in Step n is (n+1)²-2.

Measures of the given angles:

∠S = 25° and ∠R = 47°

What is an angle?

In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle.

There are two main parts related to an angle - the arms and the vertex.

Given,

Measure of angle R is 3 degrees less than twice the measure of angle S

⇒ 2∠S - ∠R = 3°

⇒ ∠R = 2∠S - 3° ------(a)

Sum of R and S

⇒ ∠R + ∠S = 72°

Substituting ∠R in terms of ∠S in above equation from equation (a)

2∠S - 3° + ∠S = 72°

3∠S - 3° = 72°

3∠S = 72° + 3°

3∠S = 75°

∠S = 75°/3

∠S = 25°

Substituting value of ∠S in equation (a)

∠R = 2 × 25° - 3°

∠R = 50° - 3°

∠R = 47°

Hence, ∠S = 25° and ∠R = 47° are the measures of given angles.
