(3-1) x (7+5) because 3-1= 2 and 7+5 is 12 then you multiply 2x12 and then you get 24. You should get smart

Answer: (3-1)×(7+5)

Step-by-step explanation:

There are mainly several ways to get 24

- 2×12

- 3×8

- 4×6

- add all of them together

- complicated ones can include large numbers minus another large number

Use try-check-revise, to find the way that fits 24

For this question, we used 2×12, which results in (3-1)×(7+5)

Hope this helps!! :)

Answer: There are 667 owls for every 1000 squirrels.

Step-by-step explanation:

Since we have given that

Number of owls = 30

Number of squirrels = 45

If the number of owls and squirrels will continue to increase.

If there are 1000 squirrels, then the number of owls would be

$\dfrac{30}{45}=\dfrac{x}{1000}\\\\x=\dfrac{30\times 1000}{45}\\\\x=666.67\\\\x\approx 667$

Hence, there are 667 owls for every 1000 squirrels.

ABC and ACD are both right angled triangles. a) explain why the length of AC is 13cm.

timofeeve [1]

Answer:

In the picture attached, the question is shown.

a) Applying Pythagorean theorem to triangle ABC, and solving for AC:

CB² + BA² = AC²

5² + 12² = AC²

√169 = AC

13 cm = AC

b) Applying Pythagorean theorem to triangle ACD, and solving for AD:

CD² + AC² = AD²

5² + 13² = AD²

√194 = AD

13.9 cm = AD
