Answer: 31

Step-by-step explanation:

Janine has 48 hockey cards in one book and 105 hockey cards in another book. Therefore, the total hockey cards will be:

= 48 + 105

= 153 hockey cards

Since the hockey cards come in packages of 5 cards, the number of packages that she will buy will be:

= 153/5

= 30 3/5

= 31

Therefore, she'll buy 31 packages

Answer:

y = 34x - 139 (y = 34x + 2)

y = [tex]\frac{3}{4}[/tex]x - 6 (y = 3/4x +2)

Step-by-step explanation:

(I'm not sure if the two equations were the same or not, but I provided the answers just in case.) Parallel lines are two lines that have the same plane and slope but never intersect. To find the equation, use the formula y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex])

Answer: 60%

If I’m understanding this problem correctly (I believe it wants me to isolate the group), we’re taking 27% (0.27) of the total men who answered the survey which equated to 45% (0.45)

First we’ll change 0.27 and 0.45 to 27 and 45. So, if 45 is our maximum, then if we divide 27 by 45, we’ll get the value 0.6–> if we multiply that by 100, we’ll get 60%.

Thus, 60% of men within that gender group preferred suspense movies.

Answer:

Combination.

167960

58344

Step-by-step explanation:

A.)

Choosing 11 players from 20 ; here the order in which the players are chosen does not matter, hence it is a combination problem.

2.)

Using nCr

n = 20 ; selection, r = 11

nCr = n! / (n-r)!r!

20C11 = 20! / 9!11!

20C11 = 167960

3.)

1 goalie 10 players

3C1 * 17C10

Answer:

7.25

Step-by-step explanation:

Given :

___________ Sample size __ sample mean

Treatment 1 ____ 5 _______ 4

Treatment 2 ____ 10 ______ 8

Treatment 3 ____ 5 _______ 9

Sample size = (5 + 10 + 5). = 20

Overall mean = ((5*4). + (10*8) + (5*9)) / 20

Overall mean = (20 + 80 + 45) / 20

= 145 / 20

= 7.25

Answer:

Get a ruler

Step-by-step explanation:

I can't really answer this because it's a measuring problem.

But I'll walk you through it.

First, grab your ruler. Once you have it, you're gonna measure the icon, so the  square picture. Make sure you measure it in centimeters (cm). Measure EACH side. Once you have the measurement of each sides, add them up to get your perimeter. The perimeter will always be length + width + length + width.

To find the area, take your length and your width and multiply them together.

For the second problem, you're going to take your measured side and multiply EACH of them by 2.5. The scale 1 cm = 2.5 mm means that for every represented centimeter in the image, the actual image is 2.5 mm. Once you have multiplied each sides by 2.5, you're going to repeat the steps above to get the perimeter and the area.

Answer:

The formula is Area = base+base/2 x height.

Step-by-step explanation:

This means that we need to add both bases, then  divide that by 2. The quotient of that gets multiplied by the height, and you have your answer.

A) endothermic process in which energy is absorbed

Step-by-step explanation:

A thermochemical reaction equation is a chemical reaction equation in which the enthalpy of reaction is written after the symbols of reactants and products.

The importance of thermochemical reaction equations is that they show us whether energy was absorbed or evolved in a reaction as well as the magnitude of energy absorbed or evolved.

When the enthalpy of reaction is positive, the reaction is endothermic and energy is absorbed. When the enthalpy of reaction is negative, the reaction is exothermic and energy is evolved or released.

The enthalpy of the reaction  I + I → I2 + 35 kcal is positive hence the reaction is an endothermic process in which energy is absorbed.

The equation shows that the formation of an iodine molecule is an A. endothermic process in which energy is absorbed.

It should be noted that an endothermic process is where heat is transferred from the surroundings to the systems. In this case, the system has gained heat from the surroundings.

The change in enthalpy, delta H is positive for an endothermic process. When the enthalpy of reaction is positive, the reaction is endothermic and energy is absorbed. The enthalpy of the reaction is positive as illustrated in this case.

Answer:

C. 60°

Step-by-step explanation:

The vertical angle formed inside a circle when two chords intersect each other is equal to half the sum of the measures of the intercepted arcs, based on the intersecting chords angle measure theorem.

Thus:

90° = ½(120° + arc TA)

Multiply both sides by 2

2*90 = 120 + arc TA

180 = 120 + arc TA

Subtract 120 from each side

180 - 120 = arc TA

60° = arc TA

Arc TA = 60°
