Answer:

Step-by-step explanation:

Use Pythagorean theorem.

Hypotenuse² = base² + altitude²

5)  x²  = 12² + 6²

         = 144 + 36

  x²  = 180

x = √180

x = 13.42 ft

6) 25² = x² + 19²

625 = x² + 361

625 - 361 = x²

x² = 264

x = √264

x = 16.25 m

7)  x² = 7² + 576

        = 49 + 576

        = 625

x = √625

x = 25 in

8)  2.5² = 2²+ x²

6.25 = 4 + x²

6.25 - 4 = x²

x² = 2.25

x = √2.25

x = 1.5 yd

In a unit circle, θ=180, the terminal point is (-1,0)

The terminal point is (-1, 0) in a unit circle at ø=180°.

A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.

In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.

In a unit circle

∵ Ф = 180°

By using the third rule above

Therefore the terminal point is (-1, 0)

2) 50%

3)20%

4)70%

5)75%

6)40%

7)56.25%

8)83.33%

Step-by-step explanation:

1) write it as a fraction 1/10 = 0.10 multiply by 100 to remove the decimal point you are left with 10 so the answer is 10%

2) write as a fraction 10/20. Simplify 10 divided by 10 =1

Answer:

[tex]\boxed {\boxed {\sf 30 \ Joules}}[/tex]

Step-by-step explanation:

Kinetic energy can be found using the following formula:

[tex]KE=\frac{1}{2}mv^2[/tex]

Where m is the mass and v is the velocity.

The robot has a mass of 60 kilograms and a velocity of 1 meter per second.

[tex]m= 60 \ kg \\v= 1 \ m/s[/tex]

Substitute the values into the formula.

[tex]KE=\frac{1}{2} (60 \ kg) (1 \ m/s)^2[/tex]

Solve the exponent first.

[tex]KE= \frac{1}{2} ( 60 \ kg )(1 m^2/s^2)[/tex]

Multiply the numbers in parentheses.

[tex]KE=\frac{1}{2} ( 60 \ kg*m^2/s^2)[/tex]

Multiply by 1/2 or divide by 2.

[tex]KE= 30 \ kg*m^2/s^2[/tex]

[tex]KE= 30 \ J[/tex]

The robot's kinetic energy is 30 Joules

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as isosceles triangle, equilateral triangle, scalene triangle, right angled triangle.

The area of triangle ABC is given as:

Area = (1/2) * AC * BC * sin(C)

But C = 50°, Area = 65.1 ft², BC = 10 ft, AC = b, AB = 13 feet.

Substituting gives:

65.1 = (1/2) * b * 10 * sin(50)

3.83b = 65.1

b = 17 ft

Perimeter of ΔABC = AB + AC + BC = 17 + 13 + 10

Perimeter of ΔABC = 40 feet

Answer:

x = (7/3,0)

y = (0,-14)

Step-by-step explanation:

make an equation

y = 6x - 14

solve

7.25h + 9(20) = 288.75

Multiply 9 by 20:

7.25h + 180 = 288.75

Subtract 180 from both sides:

7.25h = 108.75

Divide both sides by 7.25

h = 108.75 / 7.25

h = 15

Step-by-step explanation:

Answer:

y = -2x-5

Step-by-step explanation:

So to calculate the slope the equation is y1-y2/x1-x2. We substitute in two points, let's use (-3,1) as x1 and y1, and (1,-7) as x2 and y2. Put those points in the equation and you get -7-1/1-(-3), which is -2. Now you have y=-2x+b

To get b plug in a pair of points to the equations, say (1,-7). -7=-2(1)+b, solve that and you get b=-5.

So y=-2x-5.

Answer:

No. of boys = 15

Step-by-step explanation:

Given that,

The ratio of boys to student is 3:7.

Number of girls in the school = 20

We need to find the number of boys in the school.

Let there are 3x boys and 7x number of students.

No. of girls = Total students - no. of boys

= 7x-3x

= 4x

ATQ,

4x = 20

x = 5

No. of boys = 3x

= 3(5)

= 15

Hence, there are 15 boys in the school.

6.52=7

13+3+7=23

Answ

23!!!

Step-by-step explanation:

Answer:

Equation: 2x+1 = 53 (x is 26)

Integers: 26, 27

Step-by-step explanation:

53 is the sum of 2 consecutive integers. That means one of the integers is one larger than the other. This means that twice one integer plus one equals 53, so the equation becomes x + (x + 1) = 53.

x + (x+1) = 53

Combine x and x to get 2x.

2x + 1 = 53

Subtract 1 from both sides to cancel the +1.

2x = 52

Divide both sides by 2 to undo the multiplication by 2.

x = 26

With this we know the first integer is 26. The second is one more than that, so that's 27. So the two integers here are 26 and 27.
