Mathematics
1 answer:
Nimfa-mama [501]3 years ago
7 0

Answer:

21°

Step-by-step explanation:

Since these are both equivalent right triangles, ∡RQY and ∡PQY are the same. So set them equal to each other.

16x-27=5x+6

x=3

Next plug x into ∡RQY

16(3)-27=21°

It takes the high-speed train x hours to travel the z miles from Town A to Town B at a constant rate, while it takes the regular
STatiana [176]

Answer:

B

Step-by-step explanation:

To solve this, we use ratio.

Firstly, we need to know the number of hours traveled. The total number of hours traveled = x+y

Ratio of this used by high speed train = x/(x +y).

Total distance traveled before they meet = [x/(x + y)] × z

For low speed train = [y/(x + y)] × z.

The difference would be distance by high speed train - distance by low speed train.

= z [ (x - y)/x + y)]

Simplify 4( 3+ 7y) + 6(2 - y) if y =2
UkoKoshka [18]

Answer:

68

Step-by-step explanation:

The expression is given as:

4( 3+ 7y) + 6(2 - y)

It is known that y is equal to 2. Therefore, substitute 2 in for y.

4(3+7(2))+6(2-2)

Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

Solve inside of the parentheses first.

4(3+7(2))+6(2-2)

4(3+14)+6(0)

4(17)+6(0)

Multiply

68+0

A horseback rider travels 2 miles in 12 minutes. At this speed, how long does it take to travel 5 miles?
CaHeK987 [17]

Divide the time he traveled by the distance to find how fast he travels 1 mile, then multiply that by 5 miles:


12 minutes /  2 miles = 6 minutes per mile.


6 minutes per mile x 5 miles = 30 total minutes.

No. of question answered correctly = 16

Percentage of question answered correctly

(\frac{16}{20}) 100 = 80

But in order to get in the exam the student must have to score at least 90 %. But she got only 80 % so she did not qualify the exam.
