Answer:
m∠QKJ = 75°
Step-by-step explanation:
(5x - 9) + (-6 + 9x) = 111
-15 + 14x = 111
14x = 126
x = 9
m∠QKJ = -6 + 9(9) = 75

Beth normally cycles a total distance of 56 miles per week.
She increases her distance by 15% each week for the next three weeks.
How many miles will she cycle in the third week?
(3 marks)
miles
Answers
Answer:
She will cycle 85.169 miles in the third week.
(round if needed)
Step-by-step explanation:
56÷100=0.56 (this is 1%)
0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)
repeat for the other 3 weeks
64.4÷100=0.644
0.644 x 15 + 64.4 = 74.06
74.06÷100=0.7406
0.7406 x 15 + 74.06 = 85.169
Beth will cycle a distance of 85.169 miles in the third week.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If john obtained a score of 57% on his exam, that corresponds to 57 out of 100.
Beth rides her cycle 56 kilometers each week on average.
For the next three weeks, she will increase her distance by 15% each week.
As per the given condition, the required solution would be as
⇒ 56 / 100 = 0.56
⇒ 0.56 × 15 + 56 = 64.4
If we obtain 15%, add 56 (the initial amount) because there is a 15% increase.
Repeat for the remaining three weeks.
⇒ 64.4 / 100 = 0.644
⇒ 0.644 × 15 + 64.4 = 74.06
⇒ 74.06 / 100 = 0.7406
⇒ 0.7406 × 15 + 74.06 = 85.169
Therefore, she will cycle a distance of 85.169 miles in the third week.

In 5 1/2 hours of driving, Samuel traveled 264 miles. At that rate, how long would it take him to travel 348 miles?
Answers
Answer: It will take Samuel 7 1/4hours to travel 348miles
Step-by-step explanation:
Step 1
Time spent in Driving = 5 1/2 hrs
Distance he drove = 264 miles
There the speed he drove at = Distance / Time
Speed = Distance / =Tme
= 264/ 5 1/2= 264/ 11/2= 264 x 2/ 11=528/11= 48 miles per hour
Step 2
At The same rate of 48miles per hour, it will take him to travel 348 miles
Therefore the time taken = Distance / speed
Time = 348 miles/48 miles per hour
Time=7.25 = 7 1/4 Hours

Given, a color printer prints 13 pages in 4 minutes.
To calculate the time taken by the printer to print a single page, we need to divide the total time taken by the printer to the total pages printed in that particular time.
Therefore, to print a page, it will take [tex]\frac{4}{13}[/tex] minutes = [tex]0.31[/tex] minutes.

Angela wants to buy a car worth ₱950,000. He currently has ₱200,000 and plans to borrow the remaining ₱650,000 through the bank. Bank A offers an interest rate of 10% per year for 5 years where interest is computed on a simple interest basis. Bank B, meanwhile, offers an interest rate of 9% per year for 2 years but on monthly compounding. Both banks require payment only at the end of 3 years. Which bank's loan product should she choose?
Answers
Answer:
Bank A
Step-by-step explanation:
Loan amount = 650000
Bank A:
Simple interest after 3 years :
Loan amount * rate * time
650000 * 0.1 * 3 = 195,000
Bank B:
Compound interest formula :
A = P(1 + r/n)^nt
n = number of compounding times per period
A = 650000( 1 + 0.09/ 12)^12*3
A = 650000(1.0075)^36
A = 650000 * 1.3086453
A = 850619.49
Interest on payment = 850619.49 - 650,000 = 200619.49
Interest on Bank A product is lesser than Bank B

Answer: y=12 x =9
Step-by-step explanation:
In a parallelogram the diagonals bisect each other making them equal.
this means 2y + 6 = 30
we can rearrange this as 30 - 6 = 2y
24 = 2y therefore y = 12
3x - 3 = 24
We can rearrange this as 24 + 3 = 3x
3x = 27
27 / 3 = 9
x = 9

The value of ∠BDC is equal to 68°.
Step-by-step explanation:
It is given that,
∠BDA is a straight angle.
ATQ,
∠BDC+∠ADC=180 (Linear pair)
-7x+12+(-8x)+48 = 180
-7x+12-8x+48 = 180
-15x+ 60 = 180
-15x = 180-60
-15x = 120
x = -8
So,
∠BDC = -7x+12
= -7(-8) + 12
= 56+12
= 68°
So, the value of ∠BDC is equal to 68°.
