Answer:

bonds between atoms are broken and new bonds form between different atoms. This breaking and forming of bonds takes place when particles of the original materials collide with one another

Step-by-step explanation:

Answer:

during a chemical reaction, the bonds creating a specific substance break. a bond is made up of the atoms in that material. when the bonds break, they rearrange making a new substance. thus one substances changes into the other, because atoms cannot disappear or appear, they can only rearrange.

Answer:

angle C=88 degrees

Step-by-step explanation:

angles A+B+C+D=360

angles A+C=360-119-65=176

angle A=angle C because it is a kite

2C=176

angle C=88 degrees

Answer:

a

Step-by-step explanation:

-4x3=-12x

-4x-2=8x

-4x4=-16y

8+-12=-4x

-4x-16y

Answer:

A

Step-by-step explanation:

multiply each thing in the parenthesis by -4

-4×3x = -12x

-4×-2x = 8x

-4×4y = -16

-12x + 8x - 16y

combine like terms

-4x - 16y

Step-by-step explanation:

The small number above the 2 is called an exponent, and we use exponents to shorten a number so it's not so large. So here, the 6 is an exponent, and when we have a problem like this where we have to figure out something like 2^6, as shown above, we grab the base number, which in this case is 2, and we multiply it by itself 6 times, since 6 is the exponent. So basically you have to multiply the base number (2) by itself the same number of times as whatever the exponent is. So we have 2 × 2 × 2 × 2 × 2 ×2, and when you multiply all of this, you get 64. So the module has 64 pages.

Scenario a: 4x+7=64

Scenario b: 4(7+x)=64

x represents how much the bags of rice weigh in each scenario.

Answer:

c) y = - 2 x +3

d)  y = 1/2  x + 1

Step-by-step explanation:

For c) Look for the exression that contains "3" as the y-intercept (the "b" in the form y = m x + b)

The only equation is y = - 2 x +3

For d) try in all equations if replacing x with 2, gives you an answer "2" for y as well.

The only equation that does such is   y = 1/2  x + 1

Answer:

12 small boxes

8 large boxes

Step-by-step explanation:

let x be the number of small boxes shipped

let y be the number of large boxes shipped

This means:

the total number of boxes is 20, so

x + y = 20

the number of 50 pound boxes is x and the number of 100 pound boxes is y and together there are 1400 pounds, so

50x + 100y = 1400

Then, solve

First, simplify the equation 50x + 100y = 1400 by dividing both sides by 50

x + 2y = 28

Now, subtract the two equations:

x + 2y = 28

- (x + y = 20)

y = 8

Now plug this into the equation x + y = 20

x + 8 = 20

x = 12

So the number of small boxes is 12 and the number of large boxes is 8.

Here's a graph:

Answer:

-13 and 2

Step-by-step explanation:

xy= -26

x+y= -11

x= -11-y

y(-11-y) = -26

-y^2 -11y +26 = 0

y^2 +11y -26

(y+13)(y-2)

so -13 and 2

Answer:

the number of vegetables did farmer bring in the market is 1764 vegetables

Step-by-step explanation:

The computation of the number of vegetables did farmer bring in the market is shown below:

= 18 bags × 42 kgs + 28 bags × 36 kgs  

= 756 + 1008

= 1764 vegetables

Hence, the number of vegetables did farmer bring in the market is 1764 vegetables

Answer:

Step-by-step explanation:

hypotenuse (h) = 8

base(b) = 2

cos A = b / h

cos A = 2 / 8

cos A = 1/ 4

A = Cos^-1 ( 1/4)

A = 75.52 °

Answer:

Use a straightedge to connect consecutive points.

Step-by-step explanation:

C

Julie must draw a line joining the C to E, then E to D, D to F, and F to C, she will get a square into a circle.

It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).

To construct a square into the circle A.

Let's assume the CD is the diameter of the circle.

By joining the point C and point D we will get a line CD(diameter of the circle)

Draw a line EF which Bisect the line CD.

Join point E and F which are on the circle and join them.

Draw a line joinig the point C to E, then E to D, then D to F, and F to C.

We will get a square inscribed into a circle.

Thus, Julie must draw a line joining the C to E, then E to D, D to F, and F to C, she will get a square into a circle.
