Answer:

The first one: 19/15a

second one: b²-4ac = D

Step-by-step explanation:

for first one: take LCM and solve

for second one: you square the expression on both sides then b²= D + 4ac, then when you take 4ac to the left hand side, it becomes b²-4ac= D

Answer:

find y=mx+b

y=-2/3x+4

so m= -2/3

b= 4

what you want to do is start at 4 since b and go down 2 times then right 3 times or go up 2 times and left 3 times or just plug in the equation in desmos graphing calculator

Answer:

BD = 16

Step-by-step explanation:

By applying mean proportional theorem in the given right triangles,

[tex]\frac{AD}{BD}=\frac{BD}{CD}[/tex]

AD × CD = BD²

8 × 32 = BD²

BD = √256

BD = 16

Therefore, measure of side BD = 16 units.

Answer:

14.4222051019 or 14.42

Step-by-step explanation:

a^2 + b^2 = c^2

x^2 + 9^2 = 17^2

x^2 + 81 = 289

x^2 = 289 - 81

x^2 = 208

x = 14.4222051019 or 14.42

Answer:

20÷8=2,5 12÷2,5=4,8 8÷2,5=3,2 10÷2,5=4 5÷2,5=2 therefore 4,8+3,2+4+2=14

Answer:

1 1/2 tons per hour

Step-by-step explanation:

8 1/4 ÷ 5 1/2

1478 cubic feet

First, calculate volume of the shed, then minus that by the volume of the cubes...

Volume(shed) = 12*12*12 = 1728

Volume(cube) = 2.5*2.5*2.5 = 15.625

1728 - 15.625(16) = 1478 cubic feet

Total surface area is: 21 ft²

Lateral area is: 12π ft²

The total surface area of this cone is 21π square feet.

The total surface area of the cone is given by the following formula;

[tex]\rm Surface \ area=\pi r(r+l)[/tex]

Where h denotes the height of the cone and r is the radius and l is the slant height.

The radius of the cone = 3

The height of the cone = 4

Substitute all the values in the formula

[tex]\rm Surface \ area=\pi r(r+l)\\\\\rm Surface \ area=\pi 3(4+3)\\\\\rm Surface \ area=3\pi \times 7\\\\\rm Surface \ area=21\pi[/tex]

Hence, the total surface area of this cone is 21π square feet.

Answer:

En 2001 el pueblo poseía 45.826 habitantes.

Step-by-step explanation:

Un pueblo tenía 13.578 habitantes en 1970. En 1988 la población se incrementó 1,5 veces con respecto a 1970. Para calcular entonces la población en 1988 debes realizar el siguiente cálculo:

13.578*1,5= 20.367

Por lo que en 1988 el pueblo poseía 20.367 habitantes.

En 2001 se incrementó la población 2,25 veces en relación a 1988. Para calcular entonces la población en 2001 debes realizar el siguiente cálculo:

20.367* 2,25= 45.825,75≅ 45.826

Por lo que en 2001 el pueblo poseía 45.826 habitantes.

Step-by-step explanation:

The impulse of the given force is required.

The impulse of the force which is being exerted on an object of 75000 kg is 100000 Ns.

F = Force exerted on a body = 20000 N

t = Time the force was exerted for = 5.00 s

When finding the impulse of a force the mass of the object the force is being applied to does not matter. The only thing that can affect the force is if another force is being applied by the object which here is not doing so.

Impulse is given by

[tex]J=Ft\\\Rightarrow J=20000\times 5.00\\\Rightarrow J=100000\ \text{Ns}[/tex]
