In an exothermic reaction, the energy of the reactants is greater than the energy of the
products. Which of the following best explains the difference in energy between the
reactants and products?
Chemical energy from the reactants is destroyed during the reaction
Ambient energy is converted to chemical energy during the reaction
Chemical energy from the reactants is released as heat.
Chemical energy in the products is created during the reaction

Answer:

R1 = {(1, 7) (2, 7) (4, 7) (6, 7)}

R3 = {(x, y) (y, z) (z, t) (t, v)}

R1 and R3 are functions because first element in the ordered pair is not repeating, i.e they have unique images

Answer:

Between 0 and 1 goes 1/4  then after that is 5/8 then between the 1 and the 2 put 1 and 3/8/

Step-by-step explanation:

The reason for this is simply smallest to biggest. Which is bigger 1/4 or 5/8? Well if you want you can put it into a decimal: 1/4 = 0.25 and 5/8 equals 0.625. So 0.25 is closer to 1 and then 5/8 is the next closest to 1 but it is closer to 2. And lastly 1 and 3/8 is more then 0 and it's more then 1 so it goes in between 1 and 2 This is how it goes: 0   1/4    5/8  1     1 and 3/8  2

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Key skills needed: Probability, Possible Outcomes

1) We are given a spinner --> With numbers: 1,2,3,4,5,6,7, and 8

That means there are 8 numbers on the spinner.

2) The problem asks what is the probability that the spinner will not land on 5 or the 8.

To calculate this --> [tex]\frac{acceptedoutcomes}{total}[/tex]

3) The accepted outcomes are when the spinner lands on --> 1,2,3,4,6,7

That is 6 accepted outcomes.

4) The total outcomes is 8 (since there are numbers the spinner can land on).

5) Therefore, the answer would be [tex]\frac{6}{8}[/tex]

[tex]\frac{6}{8}[/tex] can be simplified into [tex]\frac{3}{4}[/tex] as both the numerator (6) and the denominator (8) share a factor of 2.

6) With this --> [tex]\frac{3}{4}[/tex] is the answer.

Answer:

X > -4

Step-by-step explanation:

2x+ 6 -4 > 4(-2+3) - 10

Answer:

x > − 4

(-4 , ∞ )

Step-by-step explanation:

If you remove the parentheses you get 2x+6-4>4*1-10

then calculate to 2x+6-4>4-10

Move the constant to the right 2x+2>-6

calculate again 2x>-6-2

Divide both side 2x>-8

Solution stated above

x > − 4

7/10 answer ///////////

The radius of the circle with point P as its center is 13.5 ft.

A circle is the locus of a point such that its distance from a fixed point is always constant (the same).

The diameter of a circle is a straight line segment that passes through the center of the circle and has endpoints on the circle.

The radius of a circle is half the diameter of the circle.

Given that the diameter of the circle is 27 ft. hence, the radius of the circle is:

Radius = Diameter / 2

Radius = 27 ft / 2 = 13.5 ft.

Hence the radius of the circle is 13.5 ft.

Answer:

$3.90

Step-by-step explanation:

multiply 1.20 x 2.25 and add the answer to 1.20

They would have to add that change up to cents because the store marks up to 225% from the prince it’s pays and we only add the 25 because if we add the 225 that changes the dollar that’s suppose to stay as 1$.

20+25=46 cents. U know it’s equals 45 cents because it’s just like counting by fives.

Answer: C: 64 cm

Step-by-step explanation:

The square has a a side of 4 centimeter meaning the area would be 16 cm. The area of the triangle is determined by half of the area of the base times the height. This mean that 4 x 6 = 24 and then 24/2 = 12. 4 x 12 = 48 (due to four triangles). 48 + 16 = 64. It is C: 64 cm

Answer:

D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.​

Step-by-step explanation:

Given that circumference of circle is: [tex]24 \pi[/tex]

The formula for circumference of circle is:

[tex]C = 2\pi r[/tex]

Comparing both formulas, we get

[tex]24\pi = 2\pi r\\24 = 2r\\r = \frac{24}{2}\\r = 12[/tex]

The radius is obtained by dividing 24 by 2.

We also know that the area of circle is:

[tex]A = \pi r^2[/tex]

The radius is being squared and then multiplied by pi to get the area.

Hence,

The correct answer is:

D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.​
