A dressmaker needs to cut 12-inch pieces of ribbon from rolls of ribbon that are 6 feet in length. How many 12-inch pieces can the dressmaker cut from 10 of these rolls of ribbon?
Before you try that problem, answer the question below.
How many \textbf{inches}inches of ribbon does the dressmaker have, in total?

Answers

Answer:

60

Step-by-step explanation:

because 12 inches is one foot so there’s 6 feet per 6 feet of ribbon and there’s 10 of these ribbons so 6 times 10 is 60

The 12-inch pieces the dressmaker can cut from 10 of these rolls of ribbon will be 60 strips .

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is given that the dressmaker has 720 inches of ribbon.

dressmaker needs to cut 12-inch pieces of ribbon from rolls of ribbon that are 6 feet in length.

The amount of rolls she has =  10 rolls

so,

6(strips per roll) x 10(amount of rolls) = 60 strips

Dimensional Analysis Method (also called conversion factor or unit analysis) (Appendix D: Dimensional Analysis, Page 397) o The dimensional analysis method uses equivalences written in _____________________ form. o Because the numerator and denominator of the fraction are equivalent, the value of the fraction is __________ o Multiplying by 1 does not change the quantity, but using an equivalence will change the units (or label) o In order for units to cancel they must be in _____________________________ of the fraction.

Answers

Answer:

The dimensional analysis method uses equivalences written in fractional form. Because the numerator and denominator of the fraction are equivalent, the value of the fraction is 1. Multiplying by 1 does not change the quantity, but using an equivalence will change the units (or label). In order for units to cancel they must be in the numerator and the denominator of the fraction

Step-by-step explanation:

Dimensional analysis is a method of problem solving that takes into consideration the identity property of multiplication whereby the product of a number and 1 will always give the same number, that is 1 × n = n whereby the value "n" remains the same after the multiplication

Therefore, a fraction of two equivalent measurements but different units has a value of 1, and multiplying the equivalent fraction with another measurement with the same unit as the denominator of the fraction with a value of 1 changes the unit to that of the unit of the numerator

Ronin kicks a ball over the gate of the first floor balcony. The function h(t)=-36t^2+288t+9 can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet 1. Find the time in Devon which the ball reaches it maximum height

Answers

Answer: 4 seconds

Step-by-step explanation:

Given: The function [tex]h(t)=-36t^2+288t+9[/tex] can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.

Differentiate the given function with respect to t , we get

[tex]h'(t)=-36(2)t+288=-72t+288[/tex]

Put h'(t)=0

[tex]\Rightarrow\ -72t+288=0\Rightarrow\ t=\dfrac{288}{72}\\\\\Rightarrow\ t=4[/tex]

Also, [tex]h''(t)=-72<0[/tex]

By second derivative test, h(t) is maximum at t=4.

Hence, the time in Devon which the ball reaches it maximum height = 4 seconds

A jacket is on sale for 40% off .The sale price is $90.00.What is the original amount of the jacket

Answers

set up a proportion
90/x = 60/100
60x = 9000
x = 150

if you're wondering why I used 60 instead of 40 in the proportion it is because $90 is 60% of the original price, not 40%

hope this helps!

The original amount of the jacket is $150.

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

A jacket is on sale for 40% off.

The sale price is $90.00.

let the Original price be x.

So, x - 40% of x = 90

x - 40x/100 = 90

x- 0.4x= 90

0.6x= 90

x= 90/0.6

x= 900/6

x= 150

Hence, the Original Price is $150.

Variable:

Equation:



Solution:

Answers

Answer:

Step-by-step explanation:

1.

(im gonna use x as a variable for all of these problems)

first to find how much each square foot costs subtract 80 from the total first

287 - 80 = 207

then divide $207 between 60 square feet

207 / 60 = $3.45

so each square foot is $3.45

our equation to find the cost would be

y = 3.45x + 80

2.

first lets find out how much the scarves are

5 x 12 = $60

then subtract that from the total

125 - 60 = $65

for 5 sister to each have 2 pairs of socks that means theres 10 pairs of socks

divide ypur rmaining money by the 10 pairs

65 / 10 = $6.50

so each pair of socks is $6.50

3.

first lets make an equation for the ymca costs

y = 15x + 20

then plug in 185 for y

185 = 15x + 20

solve for x

165 = 15x

11 = x
