Decide whether or not each equation represents a proportional relationship. A.The remaining length (L) of 120-inch rope after x inches have been cut off: 120−x=L b.The total cost (t) after 8% sales tax is added to an item's price (p): 1.08p=t c.The number of marbles each sister gets (x) when m marbles are shared equally among four sisters: x=m4 d.The volume (V) of a rectangular prism whose height is 12 cm and base is a square with side lengths s cm: V=12s2 Problem 3
Answer and Step-by-step explanation: An equation represents proportional relationship when dividing the quantities of the equation results in a quotient that is always the same. For example, in general:
Equation: y = mx
[tex]\frac{y}{x}[/tex] = m
m is a constant value, which means is the same.
A. Equation: 120 - x = L
Equation from alternative A is NOT proportional since the division of the quantities doesn't result in a constant.
B. Equation: 1.08p = t
Dividing total cost per item's price, will always give the sales tax, which is constant. So, this equation IS proportional.
[tex]\frac{t}{p}=1.08[/tex]
C. Equation: [tex]x=\frac{m}{4}[/tex]
This equation is proportional because dividing marbles per how much each sister gets, always gives the number of sisters:
[tex]\frac{m}{x}=4[/tex]
D. Equation: [tex]V=12s^{2}[/tex]
This equation is NOT proportional because side length is squared, so it is not constant linearly.
Answer:
Step-by-step explanation:
A. Equation: 120 - x = L
Equation from alternative A is NOT proportional since the division of the quantities doesn't result in a constant.
B. Equation: 1.08p = t
Dividing total cost per item's price, will always give the sales tax, which is constant. So, this equation IS proportional.
C. Equation:
This equation is proportional because dividing marbles per how much each sister gets, always gives the number of sisters:

Solve 5x - 10 <_ 20 pls help
Answer:
(-∞, 6]
Step-by-step explanation:
Step 1: Write inequality
5x - 10 ≤ 20
Step 2: Solve for x
Add 10 to both sides: 5x ≤ 30Divide both sides by 5: x ≤ 6Here we see that any value less than or equal to 6 would work.
∴ the 3rd option is our answer.
3/9 can also simplify to.....
3
2/6
1/3
Answer:
1/3
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation: 3/9 can be divided by 3 on top and bottom so 3/9=1/3 because 1 times 3 is 3 and 3 times 3 is 9 which would equal 3/9.

C5.3 PA9Fitbands' estimated sales are: October $131,982 November $195,723 December $249,283 January $124,298 February $124,284 March $124, 273 What are the balances in accounts receivable for January, February, and March if 65% of sales are collected in the month of sale, 25% is collected the month after the sale, and 10% is the second month after the sale?
Answer:
Accounts receivable in January = $68,432.60
Accounts receivable in February = $55,929.20
Accounts receivable in March = $55,958.95
Step-by-step explanation:
65% of sales collected in the month of sales + 25% in the following month + 10% in second month after sales.
In January, total accounts receivable will be the amounts outstanding or unpaid by the end of January. By the end of January, a total of 10% of December sales & 35% of January sales remain outstanding.
Accounts receivable in January = 35% of January sales + 10% of December sales
Accounts receivable in January = (35% * $124298) + (10% * $249283)
Accounts receivable in January = $43504.3 + $24928.3
Accounts receivable in January = $68432.60
In February, total accounts receivable will be the amounts outstanding or unpaid by the end of February. By the end of February, a total of 10% of January sales & 35% of February sales remain outstanding.
Accounts receivable in February = 35% of February sales + 10% of January sales
Accounts receivable in February = (35% * $124284) + (10% * $124298)
Accounts receivable in February = $43,499.4 + $12,429.8
Accounts receivable in February = $55,929.20
In March, total accounts receivable will be the amounts outstanding or unpaid by the end of march. By the end of March, a total of 10% of February sales & 35% of March sales remain outstanding.
Accounts receivable in March = 35% of March sales + 10% of February sales
Accounts receivable in March = (35% * $124373) + (10% * $124284)
Accounts receivable in March = $43530.55 + $12428.4
Accounts receivable in March = $55,958.95
What is the approximate circumference of the pizza?
Answer:
47.1cm
Step-by-step explanation:
multiply 15 cm by 3.14
Given parameters:
Radius of the pizza = 15cm
[tex]\pi[/tex] = 3.14
Unknown:
Approximate circumference of the pizza = ?
Solution:
The pizza is circular and we take the circumference of a circle to find that of the pizza;
Circumference of a circle = 2 [tex]\pi[/tex] r
Input the parameters and solve;
Circumference of a circle = 2 x 3.14 x 15 = 94.2cm
The circumference of the pizza is 94.2cm

Triangle ABC is transformed to triangle A′B′C′, as shown below:
A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes. A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0. A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0.
Which equation shows the correct relationship between the measures of the angles of the two triangles?
The measure of angle CAB = The measure of angle C prime B prime A prime
The measure of angle BCA = The measure of angle A prime B prime C
The measure of angle CAB = The measure of angle C prime A prime B prime
The measure of angle BCA = The measure of angle C prime A prime B prime low
Answer:
The measure of angle BCA = The measure of angle A prime B prime C
