First is because it doesn't keep it's pattern

it goes from 10,15, 20 to 30. it should actually be 35

the second is accurate because it keeps going up by 50

A designer creates a drawing of a triangular sign on centimeter grid paper for a new business. The drawing has sides measuring 6

ANTONII [103]

The actual length is 6*40=240 cm, 8*40=320 cm, 10*40=400 cm. And the angle measures of the actual sign will not change. The transformation can be turning over using the hypotenuse as axle. Or rotate the triangular sign 180° using the center of the triangle as the center of rotation. The turning over method will accomplish.

If the length of the minute hand of the clock in London commonly known as "Big Ben" is 11.25' from the center of the clock to th

DochEvi [55]

Answer:

33.15 square inches.

Step-by-step explanation:

Given:

Length of the minute hand is 11.25' from the center of the clock to the tip of the hand.

Question asked:

What is the area swept out by the minute hand as it moves 5 minutes of time?

Solution:

As length of the minute hand is '11.25' from the center of the clock to the tip of the hand means radius of the circle, r = 11.25 inches.

First of all we will find area of circle swept by the minutes hand,

$Area\ of\ circle=\pi r^{2}$

$=\frac{22}{7} \times11.25\times11.25\\\\ =\frac{2784.375}{7} \\ \\ =397.77\ square\ inches$

When minute hand moves 60 minutes, it makes one circle of area 397.77 square inches.

By using unitary method, we will calculate area swept by minute hand in 5 minutes:-

In 60 minutes, area swept = 397.77 square inches

In 1 minute, area swept = $\frac{397.77}{60}$

In 5 minutes, area swept = $\frac{397.77}{60}\times5=\frac{1988.85}{60} =33.15\ square\ inches$

Thus, the area swept out by the minute hand is 33.15 square inches when it moves 5 minutes.

A square with one side length is represented by the expression 4(2x+3)+16+8x. Use the properties of operations to write three di

finlep [7]

Answer:

The other sides of the square are

8x+12+16+8x,(8x+8x)+(12+16) and 16x+28

Step-by-step explanation:

Square:

The all sides of a square equal.
The sum of four angles is 360°.
The diagonals bisect each other.
The length of diagonals are equal.

Distributive property:

a(b+c)= ab+ac

Commutative property:

a+b= b+a

Like terms:

Like terms are terms that have the same variables and the power of the variable also same.

Given the length of the side is

=4(2x+3)+16+8x

=4.2x+4.3+16+8x [ Apply distributive property]

=8x+12+16+8x

=(8x+8x)+(12+16) [ separating like terms]

=16x+28 [Adding like terms]

The other sides of the square are

8x+12+16+8x,(8x+8x)+(12+16) and 16x+28

The solution to the system of equation below is (−2, −1).

diamong [38]

Answer:

Solution is given by (-2,-1)

Step-by-step explanation:

2x-3y = -1

11x-9y = -13

Multiplying equation 1 by -3 and adding it to equation 2 ,we get

-6x+9y = 3

11x -9y = -13

___________

5x = -10

gives x = -2

plugging this value in equation (1) ,we get

2(-2) -3y = -1

-4 -3y =-1

-3y =-1+4

-3y =3

y = -1

solution is (-2,-1)
