Answer:

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality". Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

Answer:

A) 19.2 ft^2

B) 28.9 ft^3

Step-by-step explanation:

Thickness = 8 inches

Assuming the triangular prism is made up of an equilateral triangle hence all sides are equal

lets assume the side = 10 inches  

lets assume the thickness as the height of the prism = 8 inches

Assume length of the rectangle(l) = 5 feet

A) The surface area of the sandwich triangular prism

total surface area = bh + 2ls + lb

                             = 10*8 + 2(5*10) + ( 5 * 10 )

                             = 80 + 100 + 50 = 230 inches = 19.2 ft^2

B ) The volume of filing in cubic feet to the nearest tenth

V = [tex]\frac{1}{4} h \sqrt{-a^4 +2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4}[/tex]  ------- 1

where : a = b = c = 10 inches

h = 8 inches

input the given values into the equation 1 above

V= 346.41 inches ^3  =  28.9 ft^3

Answer:

Total cost= $235

Step-by-step explanation:

Giving the following information:

Dontae wants to buy 100 tiles for his kitchen floor. The tiles cost $2.35.

To calculate the total cost, we need to use the following formula:

Total cost= 2.35*x

x= number of tiles

For 100 tiles:

Total cost= 2.35*100

Total cost= $235

37 is the remainder when 69,694 is divided by 93

A division is a process of splitting a specific amount into equal parts.

We have to find the remainder when 69,694 is divided by 93

The number which is getting divided here is called the dividend.

69694 is dividend

The number which divides a given number is the divisor.

93 is the divisor.

the number which we get as a result is known as the quotient.

The divisor which does not divide a number completely produces a number, which is referred to as remainder.

69694 can be written as (69657+37)

69657 is divisible completely by 93 and the remainder is 37.

Hence, 37 is the remainder when 69,694 is divided by 93

Answer:

3

Step-by-step explanation:

M is the midpoint of AB. That means that 2 binomials are equal.

4n - 40 = 7* (-2n + 2)                Remove the brackets

4n - 40 = - 14n + 14                   Add 14n to both sides

4n+14n - 40 = -14n+14n + 14     Combine

18n - 40 = 14                             Add 40 to both sides

18n = 14 + 40                           Combine

18n = 54                                   Divide by 18

18n/18 = 54/18                          Combine

Answer:

800 blue marbles

Step-by-step explanation:

Since the ratio of red to blue is 3 to 4, we know that there is 600 red marbles.

Using this information we know that 3 and 600 are both red marbles, now we multiply 3 by 200 to get a total of 600 red marbles. You can also find the value needed to multiply the 3 by dividing 600 by 3.

Since we know that 1 ratio is 200, we multiply 4 by 200 to get 800 blue marbles.

Answer:

we cry bc math is hard JKK unless ?

but fr we can write out an equation by doing (1/5 ÷ 3/4) and then switch the sign to multiplication and we can keep the first fraction the same (in this case 1/5) and then we flip the second fraction BUT when we flip the second fraction upside-down we have to change the symbol to multiplication (1/5x4/3)

then after that all we do is multiply the denominators and numerators :)

A fraction is a way to describe a part of a whole. The result of the division of the fraction is 4/15.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

The division of two fractions is carried out by multiplying the dividend fraction(Numerator) by the reciprocal of the divisor fraction(Denominator).

The divisions of the given fractions are carried out as shown below.

1/5 ÷ 3/4

[tex]=\dfrac{\dfrac{1}{5}}{\dfrac{3}{4}}\\\\\\= \dfrac{1 \times 4}{5 \times3}\\\\=\dfrac{4}{15}[/tex]

Answer: No, the experiment is not binomial

Step-by-step explanation:

From the formula for a binomial distribution :

nCx * p^k * q^(n - x)

n = number of trials (fixed)

x = number of success on trial

p = probability of success (which is the same for each trial).

q = (1 - p) = probability of failure (same for each trial)

Binomial experiment have binary outcome ; Either Success or Failure

The experiment described above :

Number of trials is satisfied (8 picks)

Binary outcome (matches on ticket or match does not exist).

The two statements that are true for parallel lines are:

The lines do not intersect.

The lines have the same slope.

Here, we have,

given that,

Two lines are parallel.

we have, given options are:

The lines do not intersect.

The lines have the same slope.

The lines intersect and form 4 right angles.

The lines intersect and form two pairs of congruent opposite angles, one acute pair and one obtuse pair.

now, we know that,

Parallel lines never intersect, and their slopes are equal.

The other two statements, that the lines intersect and form 4 right angles or two pairs of congruent opposite angles (one acute pair and one obtuse pair), are characteristics of perpendicular lines, not parallel lines.

so, we get,

Answer:

-6 < x < 2

Step-by-step explanation:

-2|2x+4|+10>-6

Subtract 10 from each side

-2|2x+4|+10-10>-6-10

-2|2x+4|>-16

Divide by -2, remembering to flip the inequality

-2/-2|2x+4|>-16/-2

|2x+4|<8

We have two solutions, one positive and one negative( remember to flip the inequality)

2x+4 < 8    and 2x+4 > -8

Subtract 4 from each side

2x+4-4 < 8-4    and 2x+4-4 > -8-4

2x < 4             and   2x > -12

Divide by 2

2x/2 < 4/2             and   2x/2 > -12/2

x <2                and           x > -6

-6 < x < 2

Answer:

x<2 and x>-6

Step-by-step explanation:

First, get rid of anything on the outside of the absolute value bars. Subtract the 10 on both sides first.

-2|2x+4|+10>-6

             -10  -10

-2|2x+4|>-16

Now, divide by -2 on both sides.

-2|2x+4|>-16

/-2           /-2

|2x+4|<8

Just so you know, any time you multiply or divide by a negative, flip the inequality sign. Now because the numbers in the absolute bars are by themselves, you can start to finally solve. But, when you have an equation with absolute bars and you have the numbers in the absolute bars by themselves, you always have to split it into two equations. The equations have to be identical, but the number on the opposite side of the x has to be negative. Now, you solve both equations just like regular ones. Also, flip the sign for the inequality with the negative number.

|2x+4|<8    and     |2x+4|>-8

     -4  -4                     -4  -4

2x<4                      2x>-12

/2  /2                      /2   /2

x<2          and          x>-6
