help geometry. find bdc

Answers

Answer:

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°.

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

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

Step-by-step explanation:

divde

Using division, the given color printer will take 0.31 minutes per page.

What is division?

Division is separating a group of items into an equal number of smaller groups. It is splitting into equal parts or groups. we use ÷ symbol or the / symbol to mean divide.

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.

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.
