ABCD is a square and triangle DEF is equilateral. Triangle ADE is isosceles with AD=AE calculate size of angle AEF
Answers
Answer:
∠AEF = 90°
Step-by-step explanation:
The size of angle AEF is given below:
Given that
ABCD is Square
CDF is a straight line
∠ADF = 90°
And triangle DEF is an Equilateral Triangle
So,
∠FDE = 60°
Now
∠ADE = 90° - 60°
= 30°
AD = AE
∠AED = 30°
∠DEF = 60° because of an equilateral triangle
Now
∠AEF = ∠AED + ∠DEF
∠AEF = 30° + 60°
∠AEF = 90°

Simplify 5x + 3 -2x + 1
Answers
Answer:
3x+4
Step-by-step explanation:
When simplifying expressions, you need to combine like terms. 5x and -2x combined would equal 3x. Since the 2x was negative, you needed to subtract. Next, you combine 3 and 1, which should equal 4.
When putting the expression back together, make sure you leave it in the same order as received. This would mean you would put the coefficient with the variable first, and then put the whole number.
Make sure to take the signs into account. If it is negative, you subtract, and if it is positive, you add.

Using PEMDAS method
P is for parenthesis
E is for exponents
M is for multiplication
18+(9*4)-27+9
= 18+36-27+9
Next is Addition

Pizazz manufactures a 5.0 oz. energy drink of the same name. Because the cans are so small, consumers are concerned that they are not receiving the full 5 ounces in each can. A quality engineer at the company is charged with analyzing the filling process and ensuring accurate readings. On 15 different occasions over the past month, she has taken a sample of 6 energy drinks off the production line and recorded their weight. The sum of the sample means is 80.20 ounces and the sum of the sample ranges is 12.68 ounces (Hint: You are already given the sum. You just have to find the x-double bar and R-bar).
Determine the control limits of an x-bar and R-chart. What is your conclusion?
Answers
Answer:
The LCL of the R-chart starts from the origin ( i.e. zero value ) while the LCL of an X -chart did not start from the origin
LCL of R-chart = 0 * 0.84533 = 0
LCL of R-chart = 75.128
Step-by-step explanation:
Given data:
number of observations = 15
sample size ( m ) = 6
sum of sample mean = 80.20 ounces
sum of sample range ( R ) = 12.68 ounces
Determine the control limits of an x-bar and R-chart
for an R-chart
LCL of R-chart = D3 * R(bar) ---- ( 1 )
where : m = 6 , D3 = 0 , R = 12.68
R(bar) = 0.84533
back to equation 1
LCL of R-chart = 0 * 0.84533 = 0
for an X-chart
LCL of X-bar) = ( mean ) - (m x R-bar)
= 80.20 - ( 6 * 0.84533 )
= 75.128
The LCL of the R-chart starts from the origin ( i.e. zero value ) while the LCL of an X -chart did not start from the origin

Answer:
9/16 inch
Step-by-step explanation:
A = 3/4 +1/16
B = 1/4
x = A - B
x = (3/4 +1/16) - (1/4) . . . an equation for the difference
x = (12/16 + 1/16) - 4/16 = (13 -4)/16
x = 9/16
The difference between A and B on the ruler is 9/16 inch.

becky spends 3/5 of her money she has left £60 left. how much money did she start with?
Answers
Answer: $150
Step-by-step explanation:
Becky spends 3/5 of her Money and is left with 2/5 of her money.
Hence 2 parts = $60
And 5 parts = $150
Becky has $150 at first.
Becky starts with $150.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Becky spends 3/5 of her money she has left £60 left.
let Becky earned be x.
so, x- 3/5x= 60
2x/5 = 60
x= 300/ 2
x=$150
Hence, Becky starts with $150.
