Answers
For the last 4; you cannot have radicals in the denominator, so you have to multiply both top and bottom by the square root, after that you just reduce.
Hope you understand, if you have any questions please let me know.

if a loan is taken out for $991 at 3% and cost 267.57 dollars how long was the loan for
Answers
Answer:
9 years.
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
t = 267.57 / ( 991 × 0.03 ) = 9
t = 9 years
The time required to
accumulate simple interest of $ 267.57
from a principal of $ 991.00
at an interest rate of 3% per year
is 9 years.

So x will be 3.9
The value of x in the given similar triangles ADB and BCE is 4.5.
To solve for x in the given similar triangles ADB and BCE, we can set up the proportion of corresponding sides:
In triangle ADB, we have:
AB/BD = x/DE
Substitute the given values:
3/4 = x/6
Now, cross-multiply and solve for x:
3 * 6 = 4x
18 = 4x
x = 18/4
x = 4.5
So, the value of x is 4.5.

Hope this helped :)
The pressure exerted by the block can be obtained as 60 N/m².
What are arithmetic operations?The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.
Since, the pressure is obtained as the ratio of Force to area.
It can be worked out using the following operation as,
Pressure = Force ÷ Area
⇒ 120 ÷ 2 = 60 N/m².
Hence, the pressure can be obtained as 60 N/m².

Find the amount of the principal on a loan at 6% interest for 140 days if the interest was $253.15, using the exact interest method. (Round to the nearest whole dollar amount)
Answers
Answer:
$11,000
Step-by-step explanation:
Given that :
Time, t = 140 days = 140/365 = 0.3835years
Interest paid = 253.15
Interest % = 6%
Principal, p =?
Using the relation :
Interest = principal * rate * time
253.15 = p * 0.06 * (140/365)
253.15 = 0.0230136p
P = 253.15 / 0.0230136
P = 11000.017
Hence, the principal amount = $11,000

7. A computer software manufacturer wanted to know if its customers were satisfied with
the graphics in a new game program called Zinger they released six months ago. The
company randomly polled 1000 of the 50,000 people who had purchased the program.
Here is part of the results of the poll:
Zinger Program Graphics Percent
Satisfied with Graphics 42%
Not Satisfied with Graphics
No Opinion 13%
a. What percent of the 1000 game users surveyed were not satisfied with the graphics
of Zinger? (2 points)
b. Based on the survey findings, how many of the current 50,000 game users would the
company expect to not be satisfied with the graphics or to have no opinion? (3
points)
c. Based on the survey findings, the software manufacturer has decided to create a new
version of the game program with improved graphics. Why did they make this
decision? (2 points)
Please I don't have any more points
Answers
Answer:
A)
45% of customers were not satisfied with the graphics.
B)
22,500 people are expected to not be satisfied with the graphics.
6,500 people are expected to have no opinion.
C)
The majority of people are unsatisfied with the graphics.
Step-by-step explanation:
The company polled 1,000 out of the 50,000 people who had purchased the program.
42% was satisfied with the graphics.
And 13% had no opinion.
Part A)
When totaled, those satisfied, unsatisfied, and with no opinion should be 100%.
Since 42% are satisfied and 13% have no opinion, this leaves 100 - 42 - 13 or 45%.
So, 45% of customers were not satisfied with the graphics.
Part B)
Since 45% of the polled were unsatisfied with the graphics, 45% of the total 50,000 can also be expected to not be satisfied.
45% of 50,000 is 0.45(50000) = 22500.
So, 22,500 people are expected to not be satisfied with the graphics.
Likewise, 13% had no opinion.
So, 13% of 50,000 is 0.13(50000) = 6500.
6,500 out of the current 50,000 customers are expected to have no opinion with the graphics.
Part C)
Since the majority of people are unsatisfied with the graphics (45% > 42%), it is reasonable to create a new version with improved graphics.

mr iniguez can bike 157 miles in 5 hours . How many miles can he bike 1 hour?
Answers
Answer: its 31.4 i think cuz if you divide 157 and 5 you get 31.4 in an hour
Step-by-step explanation:
I divided
Answer:
If he bikes 157 miles in 5 hours and we need to know hhwo many miles he can bike in 1 hour, we need to divide
157/5=31.4
Step-by-step explanation:
157 divided by 5
5 fits in 15 3 times
5x3=15
15-15=0
we bring down the 7 and 5 only fits in 7 one time
5x1 is 5 so 7-5 is 2
we add a decimal after 157 and drop it down to creat 20
5x4 is 20 so the answer is 31.4

Answers
Answer:
₱445
Step-by-step explanation:
₱18.50(x)
x = number of pineapples purchased
₱18.50(80) = ₱1480
80 - 3 = 77
₱25.00(z)
z = number of pineapples resold.
25.00(77) = ₱1925
₱1925 = ₱1480 = ₱445
