Answer:

1) This HAS a right angle

2) This is an obtuse triangle

Step-by-step explanation:

4² + 3² = 5²

16 + 9 = 25

25 = 25 ✅

5² + 6² = 8²

25 + 36 = 64

61 ≠ 64 ❌

Since c is bigger, this is an obtuse triangle

Saiges spaceship traveled 588 kilometers in 60 seconds. Determine whether or not each spaceship trip below has the same speed as

Fiesta28 [93]

Answer:

Part 1) 441km in 45s --> Has the same speed as Saige's spaceship

Part 2) 215km in 25s --> Does not have the same speed as Saige's spaceship

Part 3) 649km in 110s --> Does not have the same speed as Saige's spaceship

Step-by-step explanation:

<u><em>The complete question is</em></u>

Saige's spaceship traveled 588 kilometers in 60 seconds.

Determine whether or not each spaceship trip below has the same speed as Saige's spaceship.

441km in 45s

215km in 25s

649km in 110s

we know that

The speed is equal to divide the total distance traveled by the total time

In this problem we have that

The speed of Saiges spaceship is equal to

$\frac{588}{60}=9.8\ \frac{km}{sec}$

case 1) we have

441km in 45s

Find out the speed of the spaceship trip

$\frac{441}{45}=9.8\ \frac{km}{sec}$

Compare the speed of the spaceship trip with the speed of Saiges spaceship

$9.8\ \frac{km}{sec}=9.8\ \frac{km}{sec}$

therefore

Has the same speed as Saige's spaceship

case 2) we have

215km in 25

Find out the speed of the spaceship trip

$\frac{215}{25}=8.6\ \frac{km}{sec}$

Compare the speed of the spaceship trip with the speed of Saiges spaceship

$8.6\ \frac{km}{sec}\neq 9.8\ \frac{km}{sec}$

therefore

Does not have the same speed as Saige's spaceship

case 3) we have

649km in 110s

Find out the speed of the spaceship trip

$\frac{649}{110}=5.9\ \frac{km}{sec}$

Compare the speed of the spaceship trip with the speed of Saiges spaceship

$5.9\ \frac{km}{sec}\neq 9.8\ \frac{km}{sec}$

therefore

Does not have the same speed as Saige's spaceship

Help what is 4(3q+10)=6(2q-9)

Sergeu [11.5K]

Answer:

No solution

Step-by-step explanation:

12q + 40 = 12q - 54

There is no solution because the two equations aren't equal and each equation has the same slope bu didn't y intercept values. Therefore having no solution.

Need help ASAP! due soon!!!

-BARSIC- [3]

Answer:

Option B

Step-by-step explanation:

First make x = 4 and y = 3 in the equation y = -1/2x + 5

it should look like 3 = -1/2(4) + 5 now we can solve

-1/2 * 4 = -2 → 3 = -2 +5

-2 + 5 = 3 → 3 = 3

Please name all of the property of multiplication for 4*(-3)*5

PIT_PIT [208]

Answer:

Step-by-step explanation:

You can multiply -3 by 4 and then multiply the result of that by 5, or you could write -3, 4 and 5 in other orders (6 possible orders) and obtain the same result.

I would multiply (-3) by 4, obtaining -12, and then multiply this -12 by 5, obtaining -60. But I could also multiply 5 by 4, obtaining 20, and then multiply this 20 by -3, obtaining the same -60.

What I have described here are the commutative and associative properties of multiplication.
