Andrea used 4 1/3 yards of material to make a dress she has 1 1/4 yards left over how much material did Andrea start with
Answer:
[tex]1\frac{7}{12}\quad[/tex] yards [tex]\left(\mathrm{Decimal:\quad }\:1.58333\dots \right)[/tex]
Step-by-step explanation:
To find how much Andrea started with, subtraction is needed. To subtract, we need to set up fractions;
[tex]4\frac{1}{3}-\frac{11}{4}[/tex]
Convert the mixed number to an improper fraction: [tex]a\frac{b}{c} = \frac{a \cdot c+b }{c}[/tex][tex]4\frac{1}{3}=\frac{4\cdot 3+1}{3}[/tex]
[tex]=\frac{13}{3}[/tex]
[tex]=\frac{13}{3}-\frac{11}{4}[/tex]
Least common multiplier: 3,4 = 12
Adjust fractions based on the LCM
[tex]=\frac{52}{12}-\frac{33}{12}[/tex]
Apply the fraction rule: [tex]\quad \frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]
[tex]\frac{52}{12}-\frac{33}{12}=\frac{52-33}{12}[/tex]
[tex]=\frac{52-33}{12}[/tex]
Add the numbers: [tex]52-33=19[/tex]
[tex]=\frac{19}{12}[/tex]
Convert the improper fraction to mixed numbers: [tex]Quotient \frac{Remainder}{Divisor}[/tex][tex]\frac{19}{12}=1\frac{7}{12}[/tex]
[tex]=1\frac{7}{12}[/tex]
Therefore, Andrea started with [tex]1\frac{7}{12}[/tex] yard material.
What is the 50th term of the sequence that begins -6,0,6,12
a. 292
b. 288
c. 286
d. 290
Answer:
The 50th term of the sequence that begins with - 6 is 288.
Step-by-step explanation:
Definition of Arithmetic ProgressionAn arithmetic progression, also known as an arithmetic sequence, is a set of numbers in which the difference between successive terms remains constant. The sequence 5, 7, 9, 11, 13, 15,... is, for example, an arithmetic progression with a common difference of 2.
Formula -[tex]$a_{n}=a_{1}+(n-1) d$[/tex]
The given sequence is − 6, 0, 6, 12,It is in arithmetic progression as the common difference between all consecutive numbers is 6.
Let a1 be the first term and d be the common difference.
Therefore, a1 = - 6 and d = 6
For 50th term, a50 = a1 + (n - 1) d
= - 6 + (50 - 1) 6
= - 6 + 49 × 6
= - 6 + 294
= 288
Thus, the 50th term of the sequence is 288.

Solve for j jj. j − 2 + 7 = − 12 −2 j +7=
Answer:
j= -10/3
Step-by-step explanation:
j - 2 + 7 = - 12 - 2j + 7
*add -2 and 7 to get 5
j + 5 = -12 - 2j + 7
*add -12 and 7 to get -5
j + 5 = -5 - 2j
*add 2j to both sides
3j + 5 = -5
*subtract 5 from both sides
3j = -10
*divide both sides by 3
j= -10/3

Boston , Massachusetts, and buffalo, New York, are hit by snowstorms that last 3 days . Boston accumulates snow at a rate of 1.5 feet every 36 hours. Buffalo accumulates snow at a rate of 0.01 inches every minute.
What is the ft and in
Question is ;
Complete question is;
Boston , Massachusetts, and buffalo, New York, are hit by snowstorms that last 3 days . Boston accumulates snow at a rate of 1.5 feet every 36 hours. Buffalo accumulates snow at a rate of 0.01 inches every minute.
Which city accumulates more snow in 3 days? How much more snow?
Answer:
- Boston accumulates more snow in 3 days.
- It accumulates 0.6 ft of snow more than Boston
Step-by-step explanation:
Boston accumulates 1.5 feet of snow every 36 hours.
Number of hours in 3 days = 24 × 3 = 72 hours.
Thus, In 72 hours, Boston would have accumulated; (1.5 × 72)/36 = 3 feet of snow.
Now, Buffalo accumulates 0.01 inches of snow every minute.
In 3 days, number of minutes we have = 60 × 24 × 3 = 4320 minutes
Thus, total snow accumulated in 3 days = 0.01 × 4320/1 = 43.2 inches
Now, let's convert this to ft;
12 inches = 1ft
Thus; 43.2 inches = 43.2 × 1/12 = 3.6ft
Thus, Buffalo accumulates more snow in 3 days.
It accumulates 0.6 ft of snow more than Boston

This is a sketch plan of her garden.

5.5m
2.5m
She will leave a 50cm space between the greenhouse and the edge of the garden.
She wants a scaled plan of the garden showing the position of the greenhouse.
Draw a scale plan. Put the scale you use on the plan.
Answer:
See attachment for drawing
Step-by-step explanation:
Given
See attachment for sketch of plan
Required
Draw a scaled plan
From the question, the garden has the following dimensions.
5.5m, 5.5m, 4m and 2.5m
Using a scale of 1m : 50 cm units, the above measurements will be represented as:
[tex]5.5m \to \frac{5.5m}{50cm} \to \frac{5.5m}{0.5m} \to 11cm[/tex]
[tex]4m \to \frac{4m}{50cm} \to \frac{4m}{0.5m} \to 8cm[/tex]
[tex]2.5m \to \frac{2.5m}{50cm} \to \frac{2.5m}{0.5m} \to 5cm[/tex]
From the question, we understand that there will be 50cm space between the greenhouse and the edge.
On the scale drawing, this will be represented as:
[tex]50cm \to \frac{50cm}{50cm} \to 1cm[/tex]
From the question, the green house has the following dimensions.
2m, 2.5m
On the scale drawing, this will be represented as:
[tex]2m \to \frac{2m}{50cm} \to \frac{2m}{0.5m} \to 4m[/tex]
[tex]2.5m \to \frac{2.5m}{50cm} \to \frac{2.5m}{0.5m} \to 5m[/tex]

Avery is currently making $14 per hour at her job. Her boss gives her a 15% raise for showing good work ethic.
If she works 40 hours per week, how much more will Avery be making than before her 15% raise?
A.$15.00
B.$280.00
C.$84.00
D.$116.00
Answer:
C) $84
Step-by-step explanation:
40 x 14 = 560
she made $560 prior to raise
14 x 1.15 = 16.10
her new hourly rate is $16.10
40 x 16.1 = 644
she now earns $644 per week
644 - 560 = 84
