Answer:

4x³ - 30x² + 54x

Step-by-step explanation:

Length of the rectangular cardboard = 9 inches

Width of the rectangular cardboard = 6 inches

if the square of sides x inches is cut from each corner of the rectangular cardboard and folded to make a tray, then we have

Length of the tray = length of cardboard - 2(side of square )

= 9 - 2x

Width of the tray = width of cardboard - 2( side of square)

= 6 - 2x

height of tray = sides of square

= x

volume of tray = Length × width × height

= (9 - 2x) (6 - 2x) (x)

Open the parenthesis

= (54 - 18x - 12x + 4x²)(x)

= 54x - 18x² - 12x² + 4x³

= 54x - 30x² +4x³

Re-arrange

4x³ - 30x² + 54x

Volume, V of the tray in terms of x = 4x³ - 30x² + 54x

Thanks if you mark brainliest

The sum of all the angles of a triangle is 180 degrees.

A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

The sum of two sides of a triangle is greater then the third side. Mathematically -

a + b > c

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is the sum of the measures of the interior angles of a triangle

As discussed above, the sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

Therefore, the sum of all the angles of a triangle is 180 degrees.

Answer:

200

Step-by-step explanation:

You can use the equation 1300=4x+500

Starting bonus ($500) is like the y intercept so you would get that out of the way by subtracting 500 from both side

1300-500=800

500-500=0

Your equation is now:

800=4x

Now since the question is How many subscriptions did they sell and we know that each magazine is $4 all for have to do is divide both sides by 4 to get the answer.

800÷4=200

4x÷4=x

x=200

Answer:

The probability is 2/9

Step-by-step explanation:

Here , we want to find the probability of getting a violet ball first and a pink ball secondly if the violet ball is replaced

probability = number of balls of same color/total number of balls

The total number of balls = (2 + 4) = 6 balls

Probability of selecting a violet = 2/6 = 1/3

Probability of selecting a pink afterwards with replacement = 4/6 = 2/3

So the probability of selecting the balls in that order will be;

1/3 * 2/3 = 2/9

Answer:

7:17

Step-by-step explanation:

There are 7 girls and 10 boys taking gymnastics lessons. Write the ratio that compares the number of girls taking gymnastics lessons to the total number of students taking gymnastics lessons

Total number of students taking gymnastics classes = 7 girls + 10 boys = 17 students

Hence:

the ratio that compares the number of girls taking gymnastics lessons to the total number of students taking gymnastics lessons

= 7 : 17

The constant of proportionality is 3 inches/week

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation y = Kx also represents direct proportionality. Here, K is called constant of proportionality. It is same as slope.

We have a plant grows at a constant rate.

The data recorded by Daniel is as follows -

Week 4       12 inches

Week 5       15 inches

Week 6       18 inches

The equation y = Kx also represents direct proportionality. Here, K is called constant of proportionality. We have to find the slope of the line represented by the data as -

K = slope

K = (15 - 12)/(5 - 4)

K = 3/1

K = 3

Therefore, the constant of proportionality is 3 inches/week.

Answer:

see below

Step-by-step explanation:

a) ∠1 = 180 - 123  = 57°

b) ∠3 = 100°  (congruent to ∠18)

c) ∠4 = 180 - 100 = 80°

d) ∠5 = 123°  (opposite to ∠2)

e) ∠6 = 57°  (opposite to ∠1)

f) ∠7 = 38° (alternate angle to ∠12)

g) ∠8 = 180 - ∠7 - ∠9 = 180 - 38 - 100 = 42°

h) ∠9 = 100° (congruent to ∠18)

i) ∠10 = 57° (congruent to ∠1)

j) ∠11 = 180 - ∠10 - ∠12 = 180 - 57 - 38 = 85°

k) ∠13 = 100° (parallel angle to ∠3)

l) ∠14 = 80° (parallel angle to ∠4)

m) ∠15 = 123° (parallel angle to ∠5)

n) ∠16 =  57° (parallel angle to ∠6)

o) ∠17 = 80° (opposite angle to ∠14)

Answer: No

Step-by-step explanation: For x 0-2, the y is increasing by +5 every time. However, the moment it hits x=2, it starts decreasing by -5 every time. This means that it does not follow on set pattern (either +5 or -5) and looks more like a ^ than a /.

The answer is 82,361.49

Step-by-step explanation:

after simplifying the equation, the problem is 1290.33 divided by .27 times 3 - the quotient is 82,362.49 (in simplified form)

The amount of money that he originally invested will be $9,151.28. Then the correct option is B.

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

I = (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

When contributed at a yearly loan fee of 4.7%, a record acquired $1,290.33 of straightforward interest in 3 years.

Then the amount of money that he originally invested will be given as,

1290.33 = (P x 4.7 x 3)/100

Simplify the equation, then we have

1290.33 = (P x 4.7 x 3)/100

129033 = 14.1 x P

P = 129033 / 14.1

P = $9,151.28

The amount of money that he originally invested will be $9,151.28. Then the correct option is B.
