Answer: 40

ADE = 70 por suma de angulos interiores en triangulo ADE

En triangulos BDE y AED

AE=BE por dato

DE lado comun

AED= BED= 90

por tanto los triangulos son iguales por tener dos lados y el angulo comprendido respectivamente iguales

Luego ADE = BDE = 70 y AD=BD=BC por ser triangulos BDE y AED iguales

Luego triangulo BDC isosceles de base DC

ADE + BDE + BDC = 180 por suma de angulos consecutivos

BDC = 180 - 70 -70 = 40

Ф = BDC =BCD = 40 por ser angulos bases de un triangulo isosceles

A cone has a height of 7ft and a radius of 4ft which equation can find the volume of the cone v=1.3 (7.2)

Answers

Answer:

The volume of a cone is:

V=(hπr^2)/3, where h=height and r=radius  

V=(7π4^2)/3

V=112π/3 ft^3

V≈117.29 ft^3  (to nearest hundredth of a cubic foot)

Step-by-step explanation:

a cuboid has length 4.2 m breadth 1.4 m and height 1.2 m . find the number of cubes each of lengh 20cm ,which canbe cut from the cuboid.

Answers

l= 4.2 m = 4.2 * 100 = 420 cm

b = 1.4 m = 1.4*100 = 140 cm

h =1.2 m =1.2 *100 =120 cm

Volume of cuboid = l*b*h =  420 * 140 * 120  = 705600 cubic cm

Volume of cube = a*a*a = 20*20*20 = 8000 cubic cm

No.of cubes = Volume of cuboid / volume of cube

      = 705600 / 8000 = 882 cubes

or  420*140*120 / 20*20*20 = 42*14*12/2*2*2 = 21*7*6 = 882 cubes

A) Complete the table of values for y= x^2 - 4x


Answers

Answer:

y = x² - 4x

x = -1 y = 5

x = 0 y = 0

x = 1 y = -3

x = 2 y = - 4

x = 3 y = - 3

x = 4 y = 0

x = 5 y = 5

Hope this helps.

The equivalent values to complete the table are 5, -1, -4 and 0

Given the function according to the table shown:

[tex]y= x^2 - 4x[/tex]

When x = -1

[tex]y= (-1)^2 - 4(-1)\\y=1+4\\y=5[/tex]

When x = 1

[tex]y= (1)^2 - 4(1)\\y=1-4\\y=-3[/tex]

When x = 2

[tex]y= (2)^2 - 4(2)\\y=4-8\\y=-4[/tex]

when x = 4

[tex]y= (4)^2 - 4(4)\\y=16-16\\y=0[/tex]

Hence the equivalent values to complete the table are 5, -1, -4 and 0

A biologist uses a box-shaped fish trap that measures 1/4meter by 2/3meter by 3/5meter. What is the volume of the trap in the cubic meters.

Answers

To find the volume of a box-shaped fish trap, we have to multiply the three dimensions of it: 

(1/4 m)* (2/3 m)* (3/5 m)

= (1*2*3)/ (4*3*5) m^(3)

= 6/ 60 m^(3)

= 1/10 m^(3)

= 0.1 m^(3)

The volume of the box-shaped fish trap is 0.1 m^(3).

Which point is in the solution set of the system of inequalities
shown in the accompanying graph?
A. (0,4)
B. (2,4)
C. (-4,1)
D. (4,-1)

Answers

Answer: Option c.

Step-by-step explanation:

The dotted line means that the points in the line do not belong to the system, while the other line has all the points on the line.

Now, the point we are looking for must be a solution for both inequalities, so it must be in the region of the graph that is double shaded. (this would be the area at the left)

You now can take each point and see where it is located in the graph, if it is inside the double shaded area, then it is the correct answer.

Now, you will see that the only point that lies inside the double shaded area is the point (-4,1), so the correct option is c.

The point (-4, 1) is in the solution set of the system of inequalities.

An inequality shows the non equal comparison between two numbers or variables.

Given the inequalities as shown in the graph, the solution set of the inequalities is the point that lies on the dark shaded portion.  

The dark shaded portion is the solution of the inequality.

From the graph the point (-4, 1) lies on the dark shaded portion.

Therefore the point (-4, 1) is in the solution set of the system of inequalities.

What is the slope-intercept form of the equation of the line that passes through the points (−3, 2) and (1, 5)? Help please☹

Answers

Answer:

y=3/4x+17/4

Step-by-step explanation:

Answer:

y = (3/4)x + 17/4

Step-by-step explanation:

The slope-intercept form of the equation of the line is  y = ax + b

This line passes (-3, 2) and (1, 5)

=> 2 = a(-3) + b

=> 5 = a(1) + b

Subtraction 1st equation from 2nd equation, we have:

3 = 4a

=> a = 3/4

From 2nd equation, we have: 5 = 3/4 + b

=> b = 5 - 3/4 = 17/4

=> y = (3/4)x + 17/4
