Answer:
He needs 4 more pieces
Step-by-step explanation:
Here, we want to know the number of more string pieces that are needed
Firstly, we need to the number of string pieces obtained from the 8 2/5 inch piece
we divide 8 2/5 by 3/5
That will be;
42/5 * 5/3 = 14
So what he will get is 14 pieces from the 8 2/5 inch
The number of pieces needed is thus;
18-14 = 4
Krystal is comparing two internet service plans . Plan 1 costs $134.97 every 3 months. If krystal plans to stay with one service plans for 1 year, which which choose? How much will she save?
Answer: See explanation
Step-by-step explanation:
Here's the correct question:
Krystal is comparing two internet service plans. Plan 1 cost $34.99 per month. Plan 2 costs $ 134.97 every 3 months. If Krystal plans to stay with one service plan for 1 year which should she choose? how much will she save?
Cost of plan 1 per month = $34.99 per month. Therefore, the cost for the year would be:
= 12 × $34.99
= $419.88
Plan 2 cost $134.97 for 3 months. Therefore the cost for the year would be:
= 4 × $134.97
= $539.88
She would choose the first plan as it's cheapee. She would also save:
= $539.88 - $419.88
= $120

Raquela's coworker made price tags for several items that are to be marked down by 35%. Match each Regular Price to the correct Sale Price.
Regular Price: $4.19
Regular Price: $3.09
Regular Price: $3.77
Regular Price: $3.29
.: Sale Price: $2.01
.: Sale Price: $2.45
:: Sale Price: $2.72
: Sale Price: $2.14
9514 1404 393
Answer:
see below
Step-by-step explanation:
I like a spreadsheet for doing repetitive calculations. The matchup is shown in the attachment.
The sale price is 100% - 35% = 65% = 0.65 times the regular price.
__
Here, you can also identify the matches by putting the prices in numerical order. The lowest regular price will correspond to the lowest sale price.
regular, sale

Step-by-step explanation:
y = x - 4 and y = 4x + 2
=> x - 4 = 4x + 2
=> 3x = -6
=> x = -2
y = x - 4 = (-2) - 4 = -6
The solutions are x = -2 and y = -6.
Answer:
x = -2
y = -6
Step-by-step explanation:
y = x - 4
y = 4x + 2
y = y
then:
x-4 = 4x+2
x - 4x = 4 + 2
-3x = 6
x = 6/-3
x = -2
y = x - 4
y = -2 - 4
y = -6
Brian completed a 100 meter race in 11.74 seconds.Luis completed the race in 11.69 seconds.What was the difference between their times expressed as a fraction of a second?
Answer:
1 / 20
Step-by-step explanation:
Brian = 11.74 seconds
Luis = 11.69 seconds
Difference between their times :
11.74 - 11.69 = 0.05
Expressed as a fraction of a second :
0.05 / 1 = (0.05 * 100) / (1 * 100) = 5 /100 = 1/20

Screen-printing a batch of shirts requires 1 minute per shirt in addition to 4 minutes of initial set-up time. If it takes 41 minutes to screen-print a bath of shirts, how many shirts are in the batch?
Answer with the amount of shirts.
Answer:
There are 37 shirts in the batch.
Step-by-step explanation:
Since it takes an initial 4 minutes to set up the screen-printer, we can subtract 4 from 41 minutes to get the time used to print the shirts.
41 - 4 = 37
Since each shirt requires 1 minute of screen printing and there are 37 minutes, we can divide 37 by 1.
37 / 1 = 37
So there are 37 shirts in this batch. Hope this helps.

Can someone please explain how to solve 2.7÷0.8 step by step please
Answer: 3 and 3/8 or 27/8
Step-by-step explanation:
First step, you will need to move the decimal to the side by 1 place value.
0.8 --> 8. and 2.7--> 27.
Then just do your normal dividing.
27/8 = 3 and 3/8
The answer to 2.7÷0.8 can be either a mixed number or an improper fraction.
You have to move the decimal places to the right as many times as you need in order to make the number a while number you move the decimal place the same times as you did to the number outside the box which makes is 8 divided by 27 8 can’t go into 2 so u add a 0 and 8 can go into 27 3 times. You add a decimal point and subtract 24 from 27 u get 3 then you add a decimal point with a 0 8 can go into 30 3 times so it’s 6 add a decimal point to make it 60. Then 8 can go into 60 7 times subtract 56 from 60 and you get 4 add a decimal point and you get 40 8 can go into 40 5 times and your answer is 3.375

Find the x and y intercepts of the line 2y = 4x - 5
Divide by 2
Y = 2x - 2.5
x intercept: when y = 0
0 = 2x - 2.5
2.5 = 2x, x = 1.25
y intercept: when x = 0
Y = 2(0) - 2.5, y = -2.5
Solution: (1.25, 0) and (0, -2.5)

O is the centre of the circle and ABC and EDC are rangers to the circle. Find the side of angle BCD. You must give reason in your answer. (4marks)PLZZZZZZ HELP!!
Every line from the tangent to the centre is 90°. This is said in the circle theorems.
So angle OBC and ODC are 90°.
angle O is twice the size of angle F. This is another circle theorem.
Therefore angle O is 152°.
The quadrilateral of ODBC would equal to 360°. Which means 90° + 90° + 152° = 332°
360° - 332° = 28°.
The answer is 28°
Answer:
∠BCD = 28°
Step-by-step explanation:
arc BD = 2 x inscribed angle ∠BFD = 2 x 76 = 152
arc BFE = 360 - arc BD = 360 - 152 = 208
tangent-tangent angle ∠BCD = (arc BFE - arc BD)/2 = (208 - 152)/2 = 28

Answer: For #6, domain is {-3≤x<4}, range is {-3<y≤-1}
Step-by-step explanation: For #6 domain, the leftmost point on the graph is -3, with a closed circle. This means that x is greater than or equal to -3 (-3≤x). The rightmost point is 4, with an open circle, meaning that x is less than 4 (x<4). Put them together in the standard format, and you get {-3≤x<4}. Same principle for range; lowest point is -3, with an open circle (-3<y), and highest point is -1, with a closed circle (x≤-1). Result is {-3<y≤-1}.

if a+2b/3=2/c^9
what is 4/b
Answer:
[tex]\frac{4}{b}=\frac{8c^9}{6-3c^9a}[/tex]
Step-by-step explanation:
Given the expression
[tex]a+\frac{2b}{3}=\frac{2}{c^9}[/tex]
subtract a from both sides
[tex]a+\frac{2b}{3}-a=\frac{2}{c^9}-a[/tex]
Simplify
[tex]\frac{2b}{3}=\frac{2}{c^9}-a[/tex]
Multiply both sides by 3
[tex]\frac{3\cdot \:2b}{3}=3\cdot \frac{2}{c^9}-3a[/tex]
Simplify
[tex]2b=\frac{6}{c^9}-3a[/tex]
Divide both sides by 2
[tex]\frac{2b}{2}=\frac{\frac{6}{c^9}}{2}-\frac{3a}{2}[/tex]
Simplify
[tex]b=\frac{6-3ac^9}{2c^9}[/tex]
Calculating 4/b
[tex]\frac{4}{b}=\frac{4}{\frac{6-3ac^9}{2c^9}}[/tex] ∵ [tex]b=\frac{6-3ac^9}{2c^9}[/tex]
[tex]\frac{4}{b}\:=\frac{4\:\times \:\:2c^9}{6-3ac^9}[/tex]
[tex]\frac{4}{b}=\frac{8c^9}{6-3c^9a}[/tex]
Therefore, we conclude that:
[tex]\frac{4}{b}=\frac{8c^9}{6-3c^9a}[/tex]

How much money will be in a bank account after 4 years if $8 is deposited at an interest rate of 5%?
a.
$12.00
c.
$16.00
b.
$10.41
d.
$9.72
Answer:
$9.60
Step-by-step explanation:
The question above is a simple interest question.
The formula for the amount of money after a given period of time using simple interest is given as:
A = P(1 + rt)
Where
P = Initial Amount saved or invested = $8
R = Interest rate = 5%
t = Time in years = 4
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year.
Solving our equation:
A = 8(1 + (0.05 × 4)) = 9.6
A = $9.60
The amount of money that will be in a bank account after 4 years is $9.60
