Answer:

3 6 pks are required

Step-by-step explanation:

There are 14 people at the party

14 = 6x  where x is the number of 6 pks

Divide each side by 6

14/6 = 6x/6

2 1/3 = x

Since we cannot buy part of a 6 pk, we round up

3 6 pks are required

Answer:

Mean = 28

Step-by-step explanation:

Mean = [tex]\frac{sum of observations}{number of observations}[/tex]

Mean = [tex]\frac{12+24+24+52}{4}[/tex]

Mean = [tex]\frac{112}{4}[/tex]

Mean = 28

Answer:

10,000

Step-by-step explanation:

The bases of the scientific notation are the same, so the answer must be a base of 10. So you just divide [tex]10^{6}[/tex] and [tex]10^{2}[/tex], you should get [tex]10^{4}[/tex], which is equal to 10,000.

Answer:

1 1/2 or 1.5

Step-by-step explanation:

think: half of 4 is 2 so 1 half cup would make it to 2/4

than half of that is 1/4 which is 1/2 of 1/2 a cup

adding that to 2/4 makes it 3/4 so therefore... (Peep the answer)

Acute is the term which does not describe the given triangle.

In the given triangle with sides 11, 11 and angles 30, 30, 120 degrees:

"Acute" is a not a valid term because all angles in the triangle (30, 30, and 120 degrees) are not less than 90 degrees.

"Isosceles" is a valid term because the triangle has two equal sides (11, 11).

"Obtuse" is  applicable because an obtuse triangle have one angle greater than 90 degrees, 120 degrees is greater then 90 degrees.

Therefore, "acute" is the term that does not describe the triangle.

Answer: 112

2x+3x+10=180

5x=170

x=34

3x+10=112

The measure of the largest angle in the diagram is 112 degrees.

An angle is formed when two straight lines or rays meet at a common endpoint.

The sum of two angles is 180 degrees when they are complementary.

2x+3x+10=180

Two times of x plus three times of x plus ten equal to one hundred eighty.

5x+10=180

Five times of x plus ten equal to one hundred eighty.

Subtract 10 from both the sides

5x=170

Divide both sides by 5

x=34

Now substitute x value in 3x+10 which is largest angle.

3(34)+10

102+10

112

Hence,  the measure of the largest angle in the diagram is 112 degrees.

Elise's number is -154/7+16 = -6

Answer:

The height of the kite above the ground is 102 .44 feet

Step-by-step explanation:

To find the height of the kite above the ground, we will follow the steps below:

let h represent the height of the kite above the ground

we will use trigonometric ratio to solve

SOH CAH TOA

sinФ = opposite/hypotenuse

cosФ=adjacent / hypotenuse

tanФ=opposite / adjacent

from the diagram below

opposite = h

hypotenuse = 130 feet

Ф = 52°

The best trig ratio to use is sin

sin Ф = opposite / hypotenuse

sin52° = h / 130

cross-multiply

h = 130 sin 52°

h=102.44°

The height of the kite above the ground is 102 .44 feet

Step-by-step explanation:

Detailed comparison of the answer choices seems to be required. The x^2y terms need to sum to 10x^2y, the 3x terms need to cancel, the constant terms need to sum to -6.

The appropriate choice on this list appears to be the second choice.

Answer:

B. 333 in.2

Step-by-step explanation:

The area of the base is 81^2

lateral is 45 x 4 = 180^2  (9x5x4)

180^2 add the 72 pyramid = 252^2 + base of 81^2 = 333^2

Composite figueres i do like this as shown to you a few seconds ago.

The triangle shows us just the height

4 inches

We can see that height is smaller central isosceles height across the center base point.

We also can remember to use the length 9inches but divide by 2 and get each triangle area this way.

4 x 1/2 base = 4x 1/2 4.5 = 4 x 2.25 = 9^2 each right side triangle

9 x 8 = 72^2

we add the areas 72+ 81+lateral 180 = 333 inches^2

[tex]\dfrac{x}{2}+12=36[/tex]

Step-by-step explanation:

As it is given that

Both Riley and Francesca commute to work.

And, the Riley takes 12 minutes more than as Francesca as Riley takes 36 minutes

So for determining how many minutes is required for Francesca to get to work we need

Let us assume the time taken by Francesca to get to work is x

So, the time taken by Riley is

[tex]= \dfrac{x}{2}+12[/tex]

And, Riley takes 36 minutes to get to work.

So, the equation would be
