Answer:

The solution of the system of equation are (10,15).

Step-by-step explanation:

The given two linear two variable equations are  

- x - 2y = - 40 ........ (1) and  

x + 4y = 70 .......... (2)

Now,adding thoes two equations (1) and (2) we get,

- 2y + 4y = - 40 + 70

⇒ 2y = 30

⇒ y = 15.

Now, putting y = 15 in the equation (2), we get,

x = 70 - 4y = 70 - 4(15) = 10

Therefore, the solution of the system of equation are (10,15). (Answer)

Which of the following sets of lengths could not be the side lengths of a triangle?
docker41 [41]
To find out if the three side lengths can create a triangle, the three smaller lengths must be greater than the longer length.

\bf~Option~A

\sf~3~meters,5~meters,7~meters

\sf3+5=8>7

So this can create a triangle.

\bf~Option~B

\sf1~yard,1.25~yards,1.5~yards

\sf1+1.25=2.25>1.5

So this can create a triangle.

\bf~Option~C

\sf5~inches,10.5~inches,17~inches

\boxed{\sf5+10.5=15.5

So this cannot create a triangle.

\bf~Option~D

\sf15~millimeters,18~millimeters,30~millimeters

\sf15+18=33>30

So this can create a triangle.

Therefore, your answer is Option C.

Answer:

A) 113 m²

Step-by-step explanation:

Use the formula for area of a circle.

Area of a circle = πr²

π = pi = 3.14 (rounded)

r = radius

² = the power of 2, or the radius (in this case) multiplied by itself.

Note that the radius is given, and it is 6. Plug in 6 for the radius:

A (circle) = π(6)²

First, solve the power. Multiply 6²:

6² = 6 * 6 = 36

Next, multiply 36 with π (3.14):

36 x 3.14 = 113.04

A) 113 m² is your closest answer.
