Answer:
percent error=6%
Step-by-step explanation:
Step one:
given data
Patty counted 250
The actual amount of chocolate chips on the tray were 265
Required
The percent error
Step two:
The formula is
percent error= actual-expected/expected*100
percent error= 265-250/250*100
percent error=15/250*100
percent error=0.06*100
percent error=6%
I ate 6 pieces of my candy. This is 75% of the candy I had. How much candy did I have before
Answer:
The amount of candy you had before is 8.
Step-by-step explanation:
75% + 25% makes 100% percent.
If we take 25% off from 8, you get 6.
A quick way to do this is: 8(.25)
If you solve that, you get 2. 8 - 2 is 6, which is what you originally had.

3.7 = 5x + 12.2
Answer:
x= -1.7
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x = -1.7.
Step-by-step explanation:
3.7 = 5x + 12.2
Subtract 3.7 from both sides:
0 = 5x + 12.2 - 3.7
0 = 5x + 8.5
Subtract 5x from both sides:
-5x = 8.5
x = 8.5 / -5
x = -1.7.

1. Triangle ABC and triangle EFD are: *PLEASE HELP
Answer:
Option (3)
Step-by-step explanation:
From the figure attached,
[tex]\frac{BC}{FD}=\frac{AC}{ED}[/tex]
[tex]\frac{3}{1}= \frac{3.9}{1.3}[/tex]
[tex]\frac{3}{1}= \frac{3}{1}[/tex]
Therefore, these corresponding sides are proportional (In the same ratio).
Angle between these sides are also equal. (Given in the picture)
Since, SAS rule of similarity states that, two triangles will be similar if their corresponding two sides are proportional and angle between these two sides are equal.
Option (3) will be the answer.

16 yd
Answer:
50.24 yards=Circumference
Step-by-step explanation:
So first the formula to find circumfence is π*diameter
The diamtere is 16
π is told to be counted as 3.14
3.14*16=50.24
So the Circumfrnce is 50.24

If f(x)=2x-4 and x=4
Solve for f(x):
Answer:
dfyrexbjnyyfdc bgg hi ytdxvjud
Answer:
4
Step-by-step explanation:
f(x)=2x-4
f(x)=2(4)-4f(x)=8-4f(x)=4Just plug in 4 into x. If you get confused on what f(x) means, it basically is the output value or the y value. So when plugging in the number for f(x), I recommend not worrying about the symbol f(x) too much.

Dan,Gordon and malachy share some sweets in the ratio 2:2:5. Dan gets 24 sweets.How many did malachy get?
Answer:
60 sweets
Step-by-step explanation:
The total ratio = 2 + 2 +5 = 9
Let x = total sweets shared
Dan got 2/9 of x. This is equal to 24
the equation for this is - [tex]\frac{2}{9}[/tex] × x = 24
to solve for x, divide both sides by [tex]\frac{9}{2}[/tex]
x = 108 = total sweet shared
sweets malachy got = [tex]\frac{5}9}[/tex] x 108 = 60 sweets

A rectangle has a perimeter of 23 cm. Its area is 33 cm2. Determine the
dimensions of the rectangle. You must show all work to earn full marks. No work
shown & a correct answer will earn a mark of zero.
Answer:
length = 6 cm; width = 5.5 cm
Step-by-step explanation:
Let the length = x. Let the width = y.
We use the formulas for area and perimeter using x and y, and the given values.
area = length * width
perimeter = 2(length + width)
xy = 33
2(x + y) = 23
Solve the first equation for x:
x = 33/y
Substitute 33/y for x in the second equation.
2(33/y + y) = 23
66/y + 2y = 23
Mulrtiply both sides by y.
66 + 2y^2 = 23y
2y^2 - 23y + 66 = 0
(2y - 11)(y - 6) = 0
2y - 11 = 0 or y - 6 = 0
y = 11/2 = 5.5 or y = 6
xy = 33
x * 11/2 = 33
x = 33 * 2/11
x = 6
Answer: length = 6 cm; width = 5.5 cm
