Answer 1

Answer:

Answer:

Yes

Step-by-step explanation:

Step 1) Again - recall back to Pythagoras' Theorem: A^2+B^2=C^2 - when the squares of two of the sides of the triangle are equal to the square of the hypotenuse - then it is a Right Triangle.

Step 2) the equation will be written as such: (56/5)^2 + (21)^2 = (119/5)^2 and you render the exponents as: 125.44 + 441 = 566.44

Step 3) Add the numbers on the left: 566.44 = 566.44 - since the left equals the right, it is therefore a Right Triangle.

answer:
5c+4=2(c-5)
opening the parentheses we get:
5c+4=2c-10
putting like terms together we get
5c-2c=-10-4
3c=-14
c=-14/3

so the answer would be A. C = - 4 2/3

Mario bought $5 worth of stamps at the post office. He bought ten more 6-cent stamps than 10-cent stamps. The number of 8-cent stamps was three times the number of 10-cent stamps. He also bought two 20-cent stamps. How many of each kind of stamp did he purchase?

Answers

He bought 2 20-cent stamps.
That is $0.40.
He spent $4.60 on the other stamps.

He bought x 6-cent stamps, y 10-cent stamps, and z 8-cent stamps.

y + 10 = x
z = 3y

6x + 10y + 8z = 460

6(y + 10) + 10y + 8(3y) = 460

6y + 60 + 10y + 24y = 460

40y + 60 = 460

40y = 400

y = 10

x = y + 10 = 10 + 10 = 20

z = 3y = 3(10) = 30

He bought
20 6-cent stamps
10 10-cent stamps
30 8-cent stamps
2 20-cent stamps

Two men decide to drive to a distant town, taking the same route. The first leaves 2 hours ahead of the second and drives at 60 km per hour, while the second man drives at 90 km per hour. How many hours will it take the second man to catch up with the first man?

Answers

Answer:

$t = 6\,h$

Step-by-step explanation:

Given that both men moves at constant speed on the same trail, the motion equations that describes each motion are, respectively:

Man 1

$x = 60 \cdot t$

Man 2

$x = 90 \cdot (t-2)$

Where x is measure in kilometers and t in hours, respectively.

The time taken for both men to meet each other is:

$60\cdot t = 90\cdot (t-2)$

$30\cdot t = 180$

$t = 6\,h$

Answer: 4 hours

Step-by-step explanation:

2 x 60 =120

90-60=30

120/30= 4
