Mathematics

schepotkina [342]3 years ago

Answer:

Step-by-step explanation:

PART A

The Pythagoras theorem is expressed as

Hypotenuse^2 = opposite side^2 + adjacent side^2

PART 2

The hypotenuse is the longest side of the triangle. Looking at the given triangle, the longest side is the side with the length of 7. Therefore, hypotenuse = 7

PART C

To determine x, we will apply the Pythagoras theorem as stated above.

Opposite side = √14

Adjacent side = x

Therefore

7^2 = x^2 + (√14)^2

49 = x^2 + 14

x^2 = 49-14 = 35

Taking square root of both sides of the equation, it becomes

x = √35

x = 5.92

Please help me with this question!
mixer [17]

Hi! I'm happy to help!

To solve this, we have to divide the 18 pounds, in 1/8 portions. We do this with division. To make this problem easier to solve, we need to turn it into a multiplication problem (opposite of division). To still make the problem correct, we have to take the opposite of one of our numbers. Let's take 1/8, and turn it into 8, now we have the problem:

18×8=

Now all we have to do is multiply:

18×8=

144

He can make 144 croissants!

I hope this was helpful, keep learning! :D

I'm not very good at math
emmasim [6.3K]
Okay so, I am assuming the model is smaller so it would be 0.34m long.

The model has to be 200 times smaller than the actual plane
Divide 68/200 and you get 0.34
Then to check your answer, multiply 0.34 by 200 which is 68 meaning
0.34:68 is equal to 1:200

Assuming the model is bigger (just in case) it would be 13,600m long.

The in this scenario, the model has to be 200 times bigger so it would be 68(200) which is 13,600

Hope this helps

<em>Step-by-step explanation:</em>

<em>r² + 6r - 27 =</em>

<em>= r² + 9r - 3r - 27</em>

<em>= r(r + 9) - 3(r + 9)</em>
