Find the value of x. 6 8 4 x
The value of x in the figure which illustrates similar triangles is 3
How to determine the value of x?The figure illustrates similar triangles.
This is represented by the following equivalent ratios
x : 6 = 4 : 8
Express as fraction
x/6 = 4/8
Multiply both sides by 6
x = 6 * 4/8
Evaluate the product
x = 3
Hence, the value of x in the figure is 3

Work out the size of angle x.
105
140
Answer:
Step-by-step explanation:
Sum of angles of a triangle = 180
x + (180 - 105) + (180 -140) = 180
x + 75 + 40 = 180
x = 180 -75 - 40
x = 65

All lines are congruent to one another.
Answer:
This is false. Lines will be congruent if they have the same length, which is not the case in all situations.
Answer:
Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments.
A principal of $3000 was
invested in a savings account
for 3 years. If the interest
earned for the period was
$450, what was the interest
rate?
A=P+Prt
Answer:
r = 0.05 or 5%
Step-by-step explanation:
3450 = 3000 + (3000 · r · 3)
450 = 9000 · r
450/9000 = r
r = 0.05 or 5%

Answer:
mean = 2
median = 2.5
Step-by-step explanation:
There are a total of 20 goals (1*0 + 3*1 + 1*2 + 3*5 = 0 + 3 + 2 + 15 = 20)
There are 10 games, so 20/10 = 2 = mean
Threre are 5 games with goals greater than 2.5 and 5 games with goals below 2.5. So the median is 2.5
Based on historical data, your manager believes that 43% of the company's orders come from first-time customers. A random sample of 243 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is between 0.2 and 0.39?
Answer:
Following are the solution to the question:
Step-by-step explanation:
[tex]p = 0.43\\\\n = 243\\\\\sigma =\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.43 (1 -0.43)}{243}}=0.0013[/tex]
z-score for [tex]\hat{p}=0.2[/tex] will be:
z score for will be:
[tex]z=\frac{\hat{p}-p}{\sigma}=\frac{0.39 - 0.43}{0.0013}=-30.76[/tex]
[tex]P(0.2 <\hat{p}< 0.39) = P(-176.92 < z < -30.76)[/tex] using excel method to calculate the value.

Answer:
1) 2400 sq feet
2) $93.75
3) A (first answer)
Step-by-step explanation:
1) replace the 6 inches with 60 feet and 4 inches with 40 feet. We do this bc 1 inch = 10 feet. Then multiply 60 x 40 to get 2400 sq feet
2) we know that 25% off of 100 is 75. Then to add 25% back to 75 we find 25% of 75. 25% of 75 is 18.75. So we add 18.75 + 75 to get $93.75

Bob can type 2 letters in 4 hours while bill can do it in six. How many hours will it take them, working together, to type six letters
Answer:
7hr 12 min
Step-by-step explanation:
Given that
Bob can type 2 letters in 4 hours
while on the other hand bill can do it in six hours
We need to find out the no of hours in which they type 6 hours
So,
Bob's rate is
= 2 ÷ 4
= 1 ÷ 2 letter per hour
And,
Bill's rate is
= 2 ÷ 6
= 1 ÷ 3 letter per hour
Now
Together rate is
= 1 ÷ 2 + 1 ÷ 3 = 5 ÷ 6 letter per hour
We know that
rate × hours = production
Let us assume the hours be x
So,
(5 ÷ 6)x = 6
x = (6 ÷ 5) × 6
x = 36 ÷ 5
= 7 1 ÷ 5
= 7hr 12 min

A laptop computer is purchased for $2000. After each year, the resale value decreases by 25%. What will the resale value be after years?
Use the calculator provided and round your answer to the nearest dollar.
$[]
Answer:
2000? ... assume $2000
Resale Value = $2000*(1 - 0.25)t/yr
where: t = number of year after purchase
at t = 3 yr
Resale Value = $2000*(1 - 0.25)3 = $843.75
checking: at t = 0 $2000 (purchase price)
at t = 1 yr $2000 - 0.25*$2000 = $2000 - $500 = $1500
at t = 2 yr $1500 - 0.25*$1500 = $1500 - $375 = $1125
at t = 3 yr $1125 - 0.25*$1125 = $1125 - $281.25 = $843.75
