Alicia will construct a rectangle that has a height of 4 units and an area of up to 48 square units. Which inequality represents all the possible lengths in units of the bases, b, that Alicia can use to construct this rectangle?

Answers

Answer:

b ≤ 12

Step-by-step explanation:

The area of the rectangle is given by length multiplied by breadth.

The area of the rectangle up to 48 units square means that it can be 48 or less than 48.

If the height given is taken as the width of the rectangle then we can find the base which will be the length of the rectangle.

Area = length * breadth

4units * base ≤ 48 units square

base ≤ 48 units square/4 units

base ≤ 12 units

b ≤ 12 units

Which is the most accurate way to estimate 66% of 46?

A: 2/3 x 47
B: 1/3 x 45
C: 1/3 x 47
D: 2/3 x 45

Answers

Answer:

30 Don't use your calculator.

Step-by-step explanation:

This is an estimation question, so you have to throw your calculator out of your reach.

You have to know that 66% is nearly 2/3 So the correct answer cannot be B or C

It must be A or D.

The problem is that 3 doesn't go into 46 so you have to change it to something that is divisible by 3. Of the numbers given, the best one is 45

2/3 * 45 = 2 * 15 = 30

How close is that (remember you have to give 30 as your answer)?

The actual answer is 30.36 which makes your estimate very good.

The acceleration (in m/s/s) of a body is directly proportional to the force (in N for newton) acting on the body. If a certain body accelerates at 10 m/s/s when subjected to a force of 3 N, what will the acceleration be under a force of 8 N??

Answers

Answer:

26.667

Step-by-step explanation:

Force is directly proportional to mass and acceleration.

So Let's first bring the parameters.

F=3N, A=10m/s M=?

F=ma:.

3=Mx10,. 3=10M

M=3/10 M= 0.3

So we will use that to find the acceleration of force 8N.

F=Ma:. 8=0.3xa

8=0.3a

A=8/0.3

A=26.667.

Answer:

14 degrees is right! just wanted to add some credibility(?) idrk. best of luck!

Step-by-step explanation:

The value of x in the polygon that has six sides(hexagon) is 14.

What is a hexagon?

An hexagon is a polygon with six sides.

The exterior angles of the hexagon are as follows:

80°, 56°, 61°, 43°, 92°, and (2x)°.

Therefore,

sum of exterior angle = 360°

Hence,

80 + 56 + 61  + 43 +  92 + 2x = 360

332 + 2x = 360

2x = 360 - 332

2x = 28

x = 28 / 2

x = 14

El área de un rectángulo es 600 cm2 . Calcula las dimensiones del rectángulo sabiendo que su perímetro es 100 metros.

Answers

Answer:

Step-by-step explanation:

The area of ​​a rectangle is 600 cm2. Calculate the dimensions of the rectangle knowing that its perimeter is 100 meters.

The formula for the area of a triangle =

Length × Width = 600 cm²

LW = 600

W = 600/L

Perimeter of a rectangle = 2L + 2W = 100m

2L + 2W = 100

we substitute

2L + 2(600/L ) = 100

2L + 1200/L = 100

Multiple all through by L

2L² + 1200 = 100L

2L² - 100L + 1200 = 0

We factorise

2L² - 60L - 40L + 1200= 0

Las dimensiones del rectángulo serían:

Longitud = 30m

Ancho = 20m

Halla el largo y el ancho

Dado que,

Área del rectángulo = 600[tex]m^2[/tex]

Sabemos,

Área del rectángulo = l × b

entonces,

l × b = 600[tex]m^2[/tex]  

⇒ l = 600/b ...(i)

A continuación, tenemos,

Perímetro = 100m

Lo sabemos,

Perímetro del rectángulo = 2(l + b)

⇒ 100 = 2(l + b)

al poner (i), tenemos,

⇒ [tex]100/2 = (600/b + b)[/tex]

⇒ [tex](600 + b^2)/b = 50[/tex]

al resolver esto, obtenemos;

[tex]b^2 + 600 = 50b[/tex]

⇒ [tex]b^2 - 50b + 600 = 0[/tex]

⇒ [tex]b^2 - 30b - 20b + 600= 0[/tex]

⇒ [tex]b(b - 30) - 20(b - 30) = 0[/tex]

⇒ [tex](b - 20) (b - 30)[/tex]

∵ [tex]b = 20 m, b = 30m[/tex]

poniendo el valor de b, podemos encontrar:

[tex]l = 600/20[/tex]

∵ [tex]l = 30 m[/tex]

∵ Longitud = 30m

Ancho = 20m

Nick needs to raise at least $320 for his trip. He has $80 saved already, and he makes $40 per yard that he mows. Write and solve an inequality to solve for how many yards, "x," Nick must mow to earn the money.

Answers

Answer: Nick must now at least 6 yards.

Step-by-step explanation:

Since Nick has $80 saved already, and he makes $40 per yard that he mows, thus can be put up in an equation as:

= 80 + 40y

where y = number of yards

Since Nick needs to raise at least $320 for his trip, the equation to solve this will be:

80 + 40x ≥ 320

40x ≥ 320 - 80

40x ≥ 240

x ≥ 240/40

x ≥ 6

Therefore, Nick must now at least 6 yards.

In the diagram ABC is congruent to DEF. aging the values of x and y

Answers

Answer:

x = 1, y = 46

Step-by-step explanation:

Since the triangles are congruent then corresponding sides and angles are congruent, then

DE = AB , that is

3x + 6 = 9 ( subtract 6 from both sides )

3x = 3 ( divide both sides by 3 )

x = 1

and

∠ C = ∠ F

10x + y = 56 ( substitute x = 1 )

10(1) + y = 56

10 + y = 56 ( subtract 10 from both sides )

y = 46
