Answer:

number 1

Step-by-step explanation:

The width of the popcorn box that Mayerlin models given its dimensions and the volume is 3.2 inches.

A rectangular prism is a three-dimensional shape that is made up of six faces and 12 sides.

Volume = length x width x height

Width = volume / (length x height)

49 / (2 3/4 x 5 1/2) = 3.2 inches

Answer:3.2

Step-by-step explanation:

When you distribute, you independently multiply each term inside the parentheses by the term outside the parentheses.

So

6 x 7 = 42

and

6 x -4n = -24n

So the final answer is: 42 - 24n

*You cannot combine this answer any further since you are subtracting an unknown variable (n) from a number.

Step-by-step explanation:

Y = 3x - 10

So, 4x + 5y = 7

= 4x + 5(3x - 10) = 7

= 4x + 15x - 50 = 7

= 19x - 50 = 7

= 19x = 7 +50

= 19x = 57

= X = 57/19

X = 3

Volume

Answer:

Volume = 13.3 in³ (nearest tenth)

Step-by-step explanation:

[tex]\textsf{Volume of a cone}=\sf \dfrac{1}{3} \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}[/tex]

[tex]\textsf{Base area of a cone = area of a circle}=\sf \pi r^2[/tex]

[tex]\implies \textsf{Volume of a cone}=\sf \dfrac{1}{3} h \times \textsf{base area}[/tex]

Given:

Substituting the given values into the formula:

[tex]\begin{aligned}\implies \textsf{Volume of a cone} & =\sf \dfrac{1}{3} (8)(5)\\\\ & = \sf \dfrac{40}{3}\\\\ & = \sf 13.3\:in^3\:(nearest\:tenth)\end{aligned}[/tex]

Answer:

option b, 205

Step-by-step explanation:

Each dot on the line plot represents a different length of the ribbon,

To find the total length of the ribbon you add all the different length that was cut,

3(11.5) + 5(12) + 1(12.5) + 2(13.5) + 4(14) + 1(15)

34.5 + 60 + 12.5 + 27 + 56 + 15 = 205

Answer:

LN = 14

Step-by-step explanation:

In parallelogram diagonals bisect each other. That means that one diagonal cuts the other in half.

LJ is the diagonal and LN is a half of the diagonal.

[tex]\text{LN} = \frac{28}{2} = 14[/tex]

Since the variable x is the numerator of the fraction, we first need to multiply each side by 6, since the denominator is 6. After doing this, the equation should now look like this: [tex]18 = x + 31[/tex]. Next, we subtract 31 from 18 following the rule. 18 - 31 = -13. x is equal to -13.

For shown work in order:

[tex](6) 3 = x +31[/tex]

[tex]18 = x + 31[/tex]

[tex]18 - 31 = x[/tex]

[tex]x = -13[/tex]

Answer:

1) (Un) is a geometric sequence.

2) Un+1 - Un ≤ 0.

3) (Un) is decreasing.

4) (Un) is convergent.

5) sum = 155

Step-by-step explanation:

Un+1 = 0.5Un

U₀ = 80

1) U is a geometric sequence (reason : Un+1 = 0.5Un).

2) Un+1 - Un = 0.5Un - Un = Un×(0.5 - 1) = -0.5Un ≤ 0 (because Un ≥ 0).

Remark: use Mathematical induction to prove that Un ≥ 0

3) Un+1 - Un  ≤ 0

then

Un+1 ≤ Un  

then

the sequence U is decreasing.

4) U is decreasing and Un ≥ 0

Then U is convergent.

5)  Since U is geometric sequence with first term U0 = 80 and common ratio = 0.5 .

Important: review the sum of consecutive terms of a geometric sequence.

Then

[tex]U_0+ U_1+ U_2+ U_3+ U_4=U_{0}\times \frac{1-\left( 0.5\right)^{5} }{1-0.5}=160\times(1-\left( 0.5\right)^{5} )=155[/tex]

[tex]\begin{array}{ccll} pens&\$\\ \cline{1-2} 10 & 8\\ 2& x \end{array} \implies \cfrac{10}{2}=\cfrac{8}{x}\implies 5=\cfrac{8}{x}\implies 5x=8\implies x=\cfrac{8}{5}\implies x=1.6[/tex]

Answer:

11% of people preferred outside and non-fiction

Step-by-step explanation:

Table attached,
10/90 = 0.11

0.11 = 11% 

The percent of students in the survey that prefer outdoor activities given they prefer non-fiction is 11%.

The first step is to determine the total number of people that like fiction: 24 + 30 = 54

Now, determine the total number of people that like non-fiction: 90 - 54 = 36

The third step is to determine the total number of people that like indoor activities and non-fiction: 50 - 24 = 26

The fourth step is to determine the total number of people that like outdoor activities given they prefer non-fiction: 36 - 26 = 10

Percentage of people that prefer outdoor activities given they prefer non-fiction = (10 / 90) x 100 = 11%

The total ounces of water Diane brought are 576 ounces and  the fraction of a gallon of water did she start the hike with is 3/16.

The cost price per ounce is the amount of money required to buy one ounce of a brand or goods.

To find the cost price per ounce, divide the total amount of cost of the goods to the total number of goods.

1. There are 8 ounces in 1 cup and 16 cups in 1 gallon. Diane brought 4.5 gallons of water to a campout.  Let x ounces of water, did she bring. Thus,

[tex]x=4.5\times16\times8\\x=576\rm\; ounces[/tex]

Diane started a hike with 24 ounces of water in her backpack. The fraction of gallons in 24 ounces is,

[tex]n=\dfrac{24}{8\times16}\\n=\dfrac{3}{16}[/tex]

Thus, the total ounces of water Diane brought are 576 ounces and  the fraction of a gallon of water did she start the hike with is 3/16.
