Answer:

a=15

Step-by-step explanation:

Nice you can take your time now XD

c²-a²=b²

39²-36²=a²

1521-1296=a²

a²=225

a²=√225

a=15

Too easy! :D

To find 10, Beau found 32 = 9 and 42 = 16. He said that since 10 is between 9 and 16, 10 is between 3
AlexFokin [52]

Given that:

Consider it is \sqrt{10} instead of 10 on two places.

\sqrt{10} is between 3  and 4. So, Beau thinks a good estimate for \sqrt{10} is = 3.5.

Solution:

To find \sqrt{10}, Beau found 3² = 9 and 4² = 16.

He said that since 10 is between 9 and 16.

Since 10 is close to 9, therefore \sqrt{10} must be close to 3. So, Beau's estimate is high.

Now,

(3.1)^2=9.61

(3.2)^2=10.24

Since, 10 lies between 9.61 and 10.24, therefore \sqrt{10} must be lies between 3.1 and 3.2.

\dfrac{3.1+3.2}{2}=3.15

Therefore, the estimated value of \sqrt{10} is 3.15.

If your scale factor is 3/4, how will the scaled copy compare to the original?
Kisachek [45]
A scaled copy with the scale factor being 3/4 it would be smaller because it’s less than one so whenever there is a fraction that’s less than one then the shape would be smaller aswell

Mark wants to buy a PS5 for $499.00. If tax in her local county is 7.75% of the total sale, what is the final cost?
Effectus [21]

Assuming Mark wants to buy a PS5 for $499.00 and the  tax in her local county is 7.75% of the total sale, what will be the final cost is $538

Using this formula

Final cost =Total sales+ (Total sales×Tax)

Let plug in the formula

Final cost= $499.00+($499.00×7.75%)

Final cost= $499.00+$38.67

Final cost= $537.67

Final cost= $538 (Approximately)

Inconclusion Assuming Mark wants to buy a PS5 for $499.00 and the  tax in her local county is 7.75% of the total sale, what will be the final cost is $538
