Answer:

Step-by-step explanation:

[tex]\sqrt{}[/tex]A ^ 2 + B ^2 = C ^2 for hypotenuse

20^2 + 5^2 = C

400+25 = 425

[tex]\sqrt{425}[/tex] = 20.61

20.61 is hypotenuse.

X = 180 - 20.61 = 159.39

Answer:

39.6 cm²

Step-by-step explanation:

The formula for the area of a trapezoid is given as:

Area of a Trapezoid = 1/2(a + b) h

Where, from the question:

a = 8.9 cm

b = 5.5 cm

h = 5.5cm

Hence,

1/2 (8.9cm + 5.5cm) × 5.5cm

= 1/2 × 14.4 cm × 5.5 cm

= 39.6 cm²

Area of the Trapezoid = 39.6 cm²

Answer:

[tex]\boxed {\boxed {\sf y=-7x-9}}[/tex]

Step-by-step explanation:

Since we are given a point and the slope, we should use the point-slope  formula.

[tex]y-y_1=m(x-x_1)[/tex]

where (x₁, y₁) is the point the line passes through and m is the slope.

We know the line passes through the point (-3, 12) and the slope is -7. Therefore,

Substitute the values into the formula.

[tex]y-12=-7(x--3)[/tex]

Remember that 2 back to back negative signs become a positive.

[tex]y-12=-7(x+3)[/tex]

Now we have to put the equation in slope-intercept form, or y=mx+b. Therefore, we need to isolate the variable y on one side of the equation.

First, distribute the -7. Multiply each term inside the parentheses by -7.

[tex]y-12=(-7*x)+ (-7*3) \\y-12= (-7x)+(-21) \\y-12= -7x-21[/tex]

12 is being subtracted from y. The inverse operation of subtraction is addition. Add 12 to both sides of the equation.

[tex]y-12+12=-7x-21+12\\y= -7x-21+12\\y=-7x-9[/tex]

The equation of the line is y=-7x-9

Answer:

4/7

Step-by-step explanation:

The radius of a circle is 7 cm. Find its circumference in terms of π.

Radius (r) of a circle = 7 cm. (Given)

We know,

[tex] \dag [/tex] Circumference of a circle is 2πr.

So, its circumference is 2 × π × 7

Its circumference is 14π cm.

Answer:

Radius (r) of a circle = 7 cm. (Given)

We know,

Circumference of a circle is 2πr.

So, its circumference is 2 × π × 7

Its circumference is 14π cm.

Its circumference in terms of π is 14π cm.

Answer:

B) 5

Circle is 360 degr. So (21x+9) +(23x-5) +(26x+6)=360

Combine like terms 70x+10=360

Additive inverse -10 from both sides, 70x= 350

Divide both side by 70 division Property of Equality x=5.

Check your answer by substituting 5 back into original solution!

Step-by-step explanation:

Circle Area = pi × ( radius )^2

_________________________________

pi = 3.14

..&..

radius = diameter / 2 = 24 / 2 = 12

Thus :

Area = 3.14 × ( 12 )^2

Area = 3.14 × 144

Area = 452.16 cm^2

Answer:

Hey Love! Answer: 452.16

Step-by-step explanation:

When trying to determine area of a circle remember the formula is just pi multiplied by the radius squared

Thats just a fancy way of saying the radius x the radius x pi but REMEMBER since we dont have the radius in this problem we have to figure it out but remember that the radius is only half the diameter so our diameter is 24cm now lets divide that by 2 and we get 12cm now lets multiply that by itself so radius x radius which our radius is 12 so 12 x 12 = 144 now all we have to do is multiply that by pi so

3.14 × 144 = 452.16

Answer:

14√6.

Step-by-step explanation:

√54 = √9√6 = 3√6

√486 = √81 √6 = 9√6.

√24 = √4√6 = 2√6.

So √54 + √486 + √24

= 3√6 + 9√6 + 2√6

= 14√6.

Answer: 21.375 cm2

Step-by-step explanation:

Area of rectangle  = length x width = 3.5 x 4.4 = 15.75 cm2

Area of triangle = 1/2 x base x height = 1/2 x 2.5 x 4.5 = 5.625 cm2

Add rectangle and triangle area = 21.375 cm2

Answer:

21 /3/8 cm^2.

Step-by-step explanation:

Area = area of rectangle + area of the triangle

= 3 1/2 * 4 1/2 + 1/2 * 4 1/2 * 2 1/2

=  7/2 * 9/2 + 1/2 * 9/2 * 5/2

= 63/4 + 45/8

=  126/8 + 45/8

=  171/8

= 21 /3/8 cm^2.

Answer:

La longitud del lado del octágono es de 28 unidades.

Step-by-step explanation:

Si las longitudes de los dos lados pertenecen a un octágono regular, entonces se satisface la siguiente condición:

[tex]2\cdot x + 4 = 3\cdot x - 8[/tex] (1)

A continuación, despejamos [tex]x[/tex] en (1):

[tex]3\cdot x - 2\cdot x = 4 + 8[/tex]

[tex]x = 12[/tex]

Ahora, determinamos la longitud del lado del octágono: ([tex]x = 12[/tex])

[tex]l = 2\cdot x + 4[/tex]

[tex]l = 28[/tex]

La longitud del lado del octágono es de 28 unidades.

Answer:

56.52 cm^2

Step-by-step explanation:

curved surface area = 2πrh

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

10 / 2 = 5

2 x 3.14 x5 x 18 = 56.52 cm^2

Answer:

25 cups of tea

Step-by-step explanation:

On the x-axis, we have the number of cups of coffee plotted against the number of cups of tea which are plotted on the y-axis to represent the daily sales goals.

From the graph, when 20 cups of coffee are sold (x = 20), a corresponding sales of 25 cups of tea (y = 25) would be sold as well to meet the sales goal.

Therefore, when employees sell 20 cups of coffee, 25 cups of tea must be sold to meet their goal.

Step-by-step explanation:

Answer:

x=13

Step-by-step explanation:

100(x-3)=1000,  divide both sides by 100

100/100(x-3)=1000/100

x-3=10, add three to both sides

x-3+3=10+3

x=13
