Show how to make a ten to solve 13-7. Write the number sentence.

1 answer:

5 0

-7 + 3 + 10 = -4 + 10 = 10 - 4 = 6.

To turn 13 into 10, you need to break it up into 10 + 3, which does not change the value of 13. Then, you add 3 to -7, which results in -4. Next, you add -4 to 10 (or rather, subtract 4 from 10), which results in 6.

Juliette [100K]

Answer:

Leon is correct. (Option 1)

Step-by-step explanation:

Given that Leon verified that the side lengths 21, 28, 35 form a Pythagorean triple using this procedure.

Step 1: Find the greatest common factor of the given lengths: 7

Step 2: Divide the given lengths by the greatest common factor: 3, 4, 5

Step 3: Verify that the lengths found in step 2 form a Pythagorean triple.

we have to explain whether or not Leon is correct.

As, 3,4,5 forms a Pythagorean triplet i.e satisfies the Pythagoras theorem

$Hypotenuse^2=Base^2+Perpendicular^2$

⇒ $5^2=3^2+4^2$

Let a, b, c forms a Pythagorean triplet

$a^2+b^2=c^2$

Multiplied by 4 on both sides

⇒ $4a^2+4b^2=4c^2$

⇒ ${2a}^2+{2b}^2={2c}^2$

Hence, we say 4a, 4b and 4c also forms a Pythagorean triplet.

∴ multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.

Hence, Leon is correct.

A heron is perched in a tree 50 feet above sea level. Directly below the heron, a pelican is flying 17 feet above sea level. Dir

Elenna [48]

Answer:

Only A, E, and F are correct.

Step-by-step explanation:

The difference between two points is $P_1-P_2$ , thus the difference between the height of the Pelican and the height of the Heron is $P_p-P_h = 17ft-50ft=-33ft$ , and between the Pelican and the trout it is $P_p-P_t=17ft-(-23ft)=40ft$ .

The distance between two points is just the absolute value of the difference between them. Between the Pelican and the Heron it is $|P_p-p_h|= 33ft$ , and the distance between the Pelican and the Trout is $|P_p-P_t|=40ft$ .

Therefore,

A is correct;

B is incorrect (difference is not positive);

C is incorrect (distance cannot be negative);

D is incorrect (difference is not positive);

E is correct;

F is correct;
