  1. About 127.3(square root of 16,200, or 90√2)  Look at this problem like a right triangle.  Each leg is 90 feet, so the hypotenuse is the square root of 90^2 + 90^2
  2. About 52.3(square root of 2735.64)  Another right triangle problem!  Once again, with Pythagorean theorem (a^2 + b^2 = c^2) You can deduce that 60^2 = 29.4^2 + the width of the TV^2.
  3. About 11.6(Square root of 134.75)Another right triangle problem, you can deduce that 9.5^2 + The pool length^2 = 15^2

Hope it helps <3

(If it does, please give brainliest, only need one more for rank up :) )

Answer:

2. 18\sqrt{5}

3. 52.303...

4. 11.608...

Step-by-step explanation:

2. Using the Pythagorean Theorem, we can see that a^2+b^2=c^2. Therefore, 90^2+90^2=8100+8100=c^2. We know that 8100+8100 is 16200. The square root of 16200  is 90\sqrt{2}.

3. Same as before, we use the Pythagorean Theorem. This time, we're calculating b instead of c. This means we have to do 60^2-29.4^2=b^2, which gives us 3600-864.36, which equals 2735.64. We can put this in decimal form, which would give us 52.303...

4. This one, we do 15^2-9.5^2, which would give us 134.75. Simplifying this would give us 11.608....

Hope this helped! Just remember the Pythagorean Theorem.

Malory isn’t putting money in two savings accounts.Account A started with $150 and Account B started with $300.Malory deposits $
EastWind [94]

Given:

  • There are two savings accounts - account A has $150 and account B has $300 to begin with.
  • Malorie deposits $16 in account A and $12 in account B every month.

To Find:

The number of months where the balance of both is equal and the balance itself.

Solution:

In 37.5 months, the account balances in both accounts will be equal.

This balance will be equal to $750 in both account A and B.

Calculation:

Let x be the number of months where both the accounts have equal balance.

So, at the end of x months, 16x is the amount of money that will be added to account A (since $16 is added every month).

And the total amount at the end of x months will therefore be $(150+16x)

Similarly, at the end of x months, 12x is the amount of money that will be added to account B (since $12 will be added every month).

And the total amount at the end of x months will therefore be $(300+12x)

By our assumption, x is the number of months it will take for both the accont balances will be equal. Therefore, we have the equation

150+16x=300+12x\\4x=150\\x=37.5

Therefore, in 37.5 months, the account balances in both accounts will be equal.

This balance will be equal to 150+16(37.5)=750 i.e. $750 will be the balance in both account A and B.

(a) use the pythagorean theorem to determine the length of the unknown side of the triangle, (b) determine the perimeter of the
Kisachek [45]

Answer:

(A) 40 km

(B) 90 km

(C) 180 km²

Step-by-step explanation:

To find the missing side of this triangle, let's use the Pythagorean theorem.

a^2+b^2=c^2, assuming that a and b are legs, and c is the hypotenuse.

Assuming the 9km side is a, we need to find the value of b, so we can substitute into the equation.

9^2+b^2=41^2\\81+b^2=1681\\b^2=1681-81\\b^2=1600\\\\b = \sqrt{1600} \\b=40

So, the length of the missing side is 40. Now that we know this piece of information, we can find the perimeter and area of the triangle.

The perimeter is all the sides added together, so 41+9+40 = 90 km is the perimeter.

The area are the two legs multiplied divided by 2.

So,

\frac{9\cdot40}{2} \\\\\frac{360}{2}\\\\180

So the area of this triangle is 180 cm²

I hope this helped!
